abstract = {Gene editing in cultured cells, including the intent of sequence disruption to achieve a functional knockout of the targeted gene, has been greatly facilitated with the advent of Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) technology. Primary cell strains and immortalized cell lines from diverse tissue types have been successfully targeted both for basic research examining the effects of loss of the correlating protein and for modeling select loss-of-function disorders. Such accomplishments have extended to cutaneous cells, especially epidermal keratinocytes given their key structural and functional role in barrier formation and surveillance of and response to surface events such as triggering and processing inflammatory responses. Here we describe disruption of the Tumor Necrosis factor-induced protein 3-Interacting Protein 1 (TNIP1) gene in human HaCaT keratinocytes to generate an ongoing loss of expression as a parallel system to transient knockdown we had previously achieved with siRNA transfection. The TNIP1 protein restricts cytoplasmic progression of inflammatory signals. We cover our CRISPR/Cas9 vector choice, enrichment of transfected cells via positive selection for puromycin resistance, their subsequent cloning, and gene disruption and expression analysis. We also emphasize prior keratinocyte-CRISPR/Cas9 literature as a springboard for other investigators and to illustrate the widespread relevance of such editing to the diverse, yet highly consequentially different, genes expressed in keratinocytes.},

To leverage this technology for cutaneous biology research, we optimized a strategy for efficient gene editing in human keratinocytes, which can be grown into a differentiated organotypic epidermis to extend studies of gene function to a mature 3D tissue model. Here, we describe step-by-step methods for deploying CRISPR/Cas9 to engineer a TERT-immortalized human epidermal keratinocyte line (N/TERT-2G) to generate monoclonal heterozygous and homozygous knockout cell lines. Additionally, we provide a detailed protocol for growing gene-edited keratinocytes into organotypic epidermis, which we have used to model the pathology of monogenic dermatologic disorders that were not replicated in traditional knockout mice.},

abstract = {Marek's disease virus (MDV) and reticuloendotheliosis virus (REV) are two major immunosuppressive oncogenic viruses that severely threaten the global poultry industry. Field co-infection of these two pathogens is prevalent, accompanied by highly similar pathological lesions, making conventional diagnostic technologies incapable of rapid on-site differential identification. Recombinase polymerase amplification (RPA) coupled with the CRISPR/Cas12a system represents an innovative platform for rapid nucleic acid detection. In this study, target-specific crRNAs were designed against the conserved unique genes of MDV and REV, respectively, to establish a CRISPR-based diagnostic system capable of differentiating the two viruses for the first time. Comprehensive optimization of RPA reaction composition, buffer formulation and incubation temperature improved the overall detection performance. Three independent visual signal readout modalities were supported by this assay, including real-time fluorescence quantification, naked-eye fluorescence visualization under blue light, and lateral flow assay (LFA). Sensitivity evaluation demonstrated that the limit of detection (LOD) reached 1 × 10° copies/μL for MDV and 1 × 10[1] copies/μL for REV. Specificity assays verified that the system only generated specific positive signals in response to target viruses without cross-reactivity against other common avian oncogenic viruses and their subgroups. Blind testing of 30 clinical chick fecal specimens revealed that the assay achieved a 100% positive detection rate for both viruses when referenced to qPCR and RT-qPCR, with outstanding diagnostic efficacy and perfect detection consistency. Collectively, the developed RPA-CRISPR/Cas12a assay overcomes the limitations of traditional diagnostic methods and holds great promise for on-site routine screening in poultry farms and epidemiological surveillance of MDV and REV.},

abstract = {Septins are conserved GTP-binding cytoskeletal proteins that regulate cytokinesis, membrane dynamics, and innate immunity. Here, we report the first molecular and functional characterization of septin 8a in rohu (Labeo rohita), an economically important Indian major carp. The full-length septin 8a cDNA encodes a 420-amino acid protein containing conserved GTP-binding motifs (G1-G5) belonging to the SEPT6 subgroup with a predicted molecular weight of ∼48.98 kDa, hydrophilic character and intracellular localization consistent with cytoskeletal scaffolding. Developmental expression analysis revealed peak transcript abundance at fertilization, suggesting maternal deposition and an early embryogenic role. Tissue profiling showed the highest constitutive expression in gills, kidney, and spleen. The challenge experiments with Aeromonas hydrophila, Argulus siamensis, and the viral mimic poly I:C demonstrated a broad pathogen-induced upregulation, particularly in immune tissues. Administration of generated recombinant septin 8a in vivo activated pro-inflammatory cytokines, antimicrobial enzymes, antioxidant genes, and the MX gene, and conferred 55% relative percent survival against A. hydrophila challenge. Indirect ELISA revealed progressive increase in protein levels within liver and kidney tissues during infection. CRISPR/Cas9-mediated F0 mutagenesis in zebrafish caused developmental delay, morphological abnormalities, and a survival rate of 26%, emphasizing its role during early development. Successful mutagenesis in rohu embryos validated cross-species sgRNA efficacy. Following bacterial challenge, exon 2-edited F0 crispants showed the highest mortality (80%) relative to wild-type controls (53.33%), whereas the mortality in exon 4-edited rohu did not differ from controls. These findings establish septin 8a as a multifunctional immune regulator and developmental factor with potential applications in aquaculture disease management.},

abstract = {Hereditary ataxias, caused by expansions of short tandem repeats, are difficult to diagnose using traditional PCR and Southern blot methods, which struggle to detect complex repeat expansions and cannot assess repeat interruptions or methylation. An updated Clinical Nanopore Cas9-Targeted Sequencing workflow is presented for analyzing repeat expansions, now compatible with the Oxford Nanopore Technologies R10 flow cell. The workflow incorporates the Oxford Nanopore Technologies wf-human-variation Epi2Me workflow, including the Straglr tool to analyze base-called reads, ensuring compatibility with past, current, and future sequencing chemistries. It expands the number of genes analyzed from 10 to 27 and introduces new gene panels for ataxia, myopathy, neurodegeneration, and amyotrophic lateral sclerosis/motor neuron disease. Validated with Coriell reference and clinical samples, this method improves the analysis of pathogenic repeat expansions, providing deeper insights into repeat structures while addressing the limitations of traditional approaches. In this work, the use of multiplexing, Flongle flow cells, and single-gene targeting were explored as alternatives to panel-based approaches in the Clinical Nanopore Cas9-Targeted Sequencing workflow, finding that only single-gene targeting provides compatibility and reliable performance.},

abstract = {Pancreatic ductal adenocarcinoma (PDAC) remains a highly lethal malignancy, largely because early-stage symptoms are non-specific and diagnosis is often delayed. Although liquid biopsies (LBs) offer a promising non-invasive strategy for early detection, their clinical translation is hindered by substantial analytical limitations. This review examines the current landscape of nucleic acid-based liquid biopsy biomarkers for PDAC detection. We evaluate key limitations of established diagnostic methodologies, including next-generation sequencing (NGS) and droplet digital PCR (ddPCR). In complex biofluids, these approaches may be confounded by background signal and amplification artifacts, particularly when applied for the detection of ultra-rare targets. To address this diagnostic gap, we discuss the role of CRISPR-based biosensing and bioassay not as a replacement but as an additional specificity layer within existing diagnostic workflows. In this framework, CRISPR technologies can act as sequence-specific molecular filters that introduce an active post-amplification validation step. Although pre-analytical limitations remain to be fully characterized, integrating CRISPR into the diagnostic workflow may contribute to a rapid, cost-effective, and highly specific framework for the early detection of PDAC.},

abstract = {Tumor necrosis factor-α (TNF-α) is an important inflammatory cytokine whose rapid and quantitative detection is essential for disease diagnosis and monitoring. However, conventional methods are often limited by bulky instrumentation and are not well suited for analysis in complex biological environments. Herein, a portable CRISPR/Cas12a-based aptasensor system was developed for detection of TNF-α by integrating aptamer recognition, Cas12a trans-cleavage signal amplification, and a miniaturized fluorescence detection device. An aptamer for TNF-α was designed to regulate the accessibility of the target sequence to the CRISPR RNA (crRNA), and the resulting change in Cas12a activity was converted into fluorescence signals. The portable device integrated light-emitting diode (LED) excitation and photodiode-based detection, with modulated signals wirelessly transmitted to a smartphone for readout. The aptasensor showed concentration-dependent responses, and the inhibition rate exhibited a linear relationship with TNF-α concentration. The applicability of the system was validated in cell culture supernatants and cervical tissue samples, including tumor and adjacent normal tissues. Distinct TNF-α levels were observed between these samples, showing good agreement with enzyme-linked immunosorbent assay (ELISA) results. This portable CRISPR/Cas12a aptasensor system provides a practical approach for point-of-care TNF-α detection and extends CRISPR-based sensing to protein biomarkers.},

abstract = {CRISPR/Cas12a diagnostics have greatly advanced nucleic acid testing, yet their extension to non-nucleic acid targets remains constrained by the intricate preamplification process and by inefficient signal transduction. Herein, we present a non-nucleic acid detection platform that integrates a CRISPR/Cas12a positive-feedback cascade with a single-atom nanozyme. In this strategy, cleavage of the designed double-clasp transition probe (DCTP) activates additional Cas12a ribonucleoprotein (RNP) complexes, enabling cascade signal amplification without a preamplification treatment. Meanwhile, the created single-atom Pt-engineered PdCeB nanozyme (Pt1/PdCeB SAN) functions as an efficient electrochemiluminescence (ECL) nanolabel in the luminol/O2 system, converting dissolved oxygen (O2) into reactive oxygen species (ROS) to produce a robust ECL response without an external coreactant. Using human epidermal growth factor receptor 2 (HER2) as a clinically relevant non-nucleic acid target, the DCTP-driven Cas12a positive-feedback system shortened the cleavage time from 33 min in the conventional Cas12a system to 18 min and achieved a wide linear range from 10-3 to 104 ng/mL, with a low detection limit of 0.513 pg/mL. Furthermore, preliminary analysis of 31 clinical serum samples supported the feasibility of the strategy for quantitative serum HER2 (sHER2) determination, although validation in larger independent cohorts is required.},

abstract = {Rapid and accurate diagnostics are essential for controlling emerging infectious diseases and antimicrobial resistance, yet CRISPR assays with exceptional analytical sensitivity often remain difficult to translate into deployable tests. Existing reviews have commonly organized CRISPR diagnostics by Cas effector, biosensor format, or application, offering limited guidance on how design decisions interact across complete workflows or why promising systems remain at the proof-of-concept stage. We introduce an integrated framework that connects five coupled design layers with five levels of translational evidence. The design layers comprise guide RNA engineering, signal amplification circuits, molecular adaptors, computational design support, and specimen and intended-use implementation. The evidence levels progress from purified-target characterization and spiked-matrix testing to retrospective specimen evaluation, prospective integrated-workflow evaluation, and intended-use operation by target users supported by controls, usability assessment, real-time stability, manufacturing consistency, cost per valid result, and claim-specific regulatory preparation. This dual framework shows how improvements at one layer can shift the dominant bottleneck to another. For example, preamplification can lower the analytical limit of detection while increasing contamination risk and workflow burden, whereas guide designs that improve sequence discrimination may reduce cognate-target activation. The framework supports bottleneck-guided selection of effectors, signal-gain strategies, adaptors, computational tools, and multiplexing formats according to target type and abundance, specimen matrix, intended decision, target users, and deployment setting. High analytical sensitivity or single-nucleotide discrimination under controlled conditions does not establish clinical utility unless such performance improves classification at the intended decision threshold within the complete workflow. Translation requires standardized benchmarking, matrix-aware validation, appropriate controls, stability and manufacturability assessment, prospective intended-use studies, and economic evaluation suited to the intended claim and setting. This framework shifts the evaluation of CRISPR diagnostics from isolated analytical performance toward evidence-based workflow co-design.},

abstract = {Mutations in isocitrate dehydrogenase (IDH) are frequently observed in several aggressive malignancies, including gliomas, chondrosarcomas, and acute myeloid leukemia. Mutant IDH enzymes exhibit neomorphic activity that produces the oncometabolite D-2-hydroxyglutarate (D-2-HG), leading to widespread DNA and histone hypermethylation. This aberrant epigenetic state remodels chromatin accessibility, thereby compromising both DNA repair and replication. However, the mechanisms underlying IDH mutation-induced DNA replication stress and the therapeutic potential of this vulnerability remain elusive. Through a whole-genome CRISPR screen, we defined differential genetic dependencies between IDH1 wild-type and mutant cells. We identified the G2/M checkpoint kinase PKMYT1 as a selective survival factor for IDH1-mutated cells. Pharmacologic or genetic inhibition of PKMYT1 profoundly suppresses the growth of IDH1-mutated tumor cells in vitro and in vivo. Mechanistically, IDH1-mutated cancer cells exhibit profound replication stress, characterized by reduced nucleotide incorporation, slowed replication fork progression, and delayed S-phase entry. D-2-HG elevates H3K9 trimethylation by inhibiting KDM4A, thereby impeding DNA replication initiation and fork progression. PKMYT1 blockade alters cell cycle timing, forcing unscheduled mitotic entry with incompletely replicated genomes, resulting in elevated DNA damage and mitotic catastrophe. Collectively, our findings demonstrate a mechanistic link between IDH1-driven epigenetic dysregulation, replication stress, and heightened reliance on the G2/M checkpoint. Our findings propose PKMYT1 inhibition as a therapeutic strategy that exploits the intrinsic replication deficiency of IDH1-mutant glioma.},

abstract = {Nipah virus (NiV) is a highly lethal zoonotic pathogen, and existing rapid diagnostic tools are scarce and reliant on nucleic acid amplification. In this study, we designed and fabricated a thin-film field-effect transistor with an IGZO channel and, for the first time, combined a discrete AuNP floating gate with the CRISPR/Cas13a system to achieve amplification-free detection of NiV. A pair of partially complementary nucleic acid reporter probes was used to attach AuNPs onto the channel, forming a nucleic acid-functionalized discrete floating gate. Under positive gate voltage, the AuNPs electrostatically induce mirror charges in the IGZO channel, amplifying the sensing signal. Additionally, the electrons can be injected from AuNPs into the channel via the Fowler-Nordheim tunneling effect under negative gate voltage, as a potential complementary sensing mechanism. The AuNPs are immobilized via nucleic acid strands, ensuring good biocompatibility. CrRNA was designed and the CRISPR system was optimized for compatibility with the FET, achieving amplification-free detection of NiV standards down to 10° copies/μL within 10 min. This study not only provides a reliable and rapid detection tool for NiV but also establishes a biosensing framework applicable to other pathogens.},

abstract = {Portable detection of soil-borne pathogens is constrained by laborious soil sample preparation and nucleic acid extraction. Here, we report a centrifugal Soil-on-a-Disc (SoaD) microfluidic chip for rapid soil-to-DNA preparation with automated on-chip clarification and DNA purification, combined with a CRISPR/Cas12a-based quantum dot (QD) fluorescent lateral flow assay (LFA) and smartphone-based fluorescence analysis for the portable detection of Phytophthora infestans (P. infestans). The seven-layer PMMA disc integrates cascaded 5 and 0.8 μm membranes for stepwise particle filtration, together with a silica membrane and active puncture valves for sequential DNA capture, washing, and elution under centrifugal control. The SoaD chip reduced the turbidity of soil suspensions significantly from 12,980 NTU to below the detection limit (∼0 NTU), yielding a clarified sample matrix for downstream DNA extraction, and completed DNA extraction within 20 min. Compared with a commercial soil DNA kit, the relative total DNA recovery efficiency for P. infestans-spiked soils was 94.9 ± 3.3%. Coupled with downstream recombinase polymerase amplification and smartphone-assisted fluorescence readout, the system achieved a limit of detection of 0.135 ng/μL for PiNW-derived RPA products and detected P. infestans in soils spiked at levels as low as 1 spore/g. As a secondary validation of extraction compatibility, 16S rRNA/ITS amplicon sequencing showed that chip-prepared DNA yielded bacterial and fungal community profiles highly consistent with those obtained using the commercial soil DNA kit (r = 0.996/0.923). This work advances portable CRISPR-based sensing toward complex soil samples and provides a field-oriented strategy for molecular surveillance of soil-borne plant diseases.},

abstract = {Fluorescence-based CRISPR diagnostic assays have become a popular platform for nucleic acid detection due to their programmability, configurability, specificity, and compatibility with standard laboratory equipment. However, reported enzymatic kinetic rates and limits of detection for CRISPR trans-cleavage assays vary by several orders of magnitude across the literature. This variation in performance parameters is coupled with, and exacerbated by, inconsistent calibration, incomplete correction of measurement biases, and nonstandardized or incomplete data analysis procedures. We present an experimental protocol and quantitative analysis framework for fluorescence-based enzyme assays using routine laboratory instrumentation, including thermocyclers and fluorescence microplate readers. Building on previous studies of CRISPR enzyme kinetics and fluorescence calibration, we describe procedures for flat-field and background correction; comprehensive fluorescence calibration, including correction for the inner filter effect; quantification and implications of reporter degradation; extraction of Michaelis-Menten kinetic parameters; and determination of assay's limits of detection. We provide step-by-step experimental guidelines and open-source Python implementations for each stage of the workflow. Using representative Cas12 trans-cleavage datasets, we demonstrate that explicit fluorescence calibration and correction procedures substantially reduce systematic bias in measured kinetic rates and improve consistency between experiments. Our framework aims to establish standardized practices for quantitative fluorescence-based CRISPR assays and provides researchers with practical tools for reproducible kinetic characterization and rational assay design.},

abstract = {OBJECTIVE: To determine if common genetic variants at the chromosome 1p13 locus which predisposes to Paget's Disease of Bone (PDB) regulate Macrophage Colony stimulating factor (M-CSF) expression in bone cells and to determine if there is dysregulation of M-CSF in patients with PDB.

METHODS: The regions surrounding single nucleotide polymorphisms (SNP) previously associated with PDB at a genome wide significant level were deleted in clones of MG63 osteoblast-like cells using CRISPR/Cas and levels of M-CSF mRNA and protein were evaluated in cells with and without deletions. Serum M-CSF was measured by ELISA in PDB and controls and values in patients were related to clinical features of PDB and biochemical markers of bone remodelling.

RESULTS: Deletion of the region surrounding rs484959 increased expression of M-CSF mRNA by 1.31 fold [95%,1.04-1.58], p = 0.026 and M-CSF protein by 1.91 fold [1.25-2.57], p = 0.013, compared with control cells. Serum M-CSF was significantly elevated in PDB versus controls (mean ± SD = 781.7 ± 678 vs. 541 ± 491 pg/mL, p < 0.001). Furthermore, M-CSF levels were associated with number of affected bones (p = 0.029), bodily pain assessed by SF-36 (p = 0.026) and biochemical markers of bone turnover.

CONCLUSION: The rs484959 SNP is a regulatory variant which modulates M-CSF mRNA and protein expression in osteoblasts. Serum M-CSF is increased in PDB, is associated with pain, disease extent and biochemical markers of bone remodelling. This suggest that there is dysregulation of M-CSF in PDB and that this cytokine may play a role in pathogenesis of the disease.},

abstract = {This protocol describes a method for endogenous protein tagging in postmitotic primary neurons using homology-independent targeted integration (HITI), a CRISPR/Cas9-based approach that exploits non-homologous end joining (NHEJ). Unlike homology-directed repair (HDR), HITI does not require cell division, making it uniquely suited for postmitotic neurons. SpCas9 is delivered by a replication-incompetent simian immunodeficiency lentiviral vector (pLenti SIV), while the sgRNA, donor tag cassette, and a fluorescent plasma membrane marker are co-packaged in a single AAV vector. The two vectors are co-delivered at DIV5, and endogenous tagging is assessed at DIV15-23. The workflow is illustrated using Junctophilin-3 (JPH3) tagged with mEmerald at its endogenous locus. Airyscan microscopy imaging of endogenously tagged JPH3 at native expression levels revealed its localization at endoplasmic reticulum-plasma membrane (ER-PM) contact sites and uncovered a periodic distribution of ER-PM junctions along the dendritic arbor, enabling identification of a previously unrecognized ladder-like organization of the ER in neuronal dendrites. Genomic integration of the tag is validated at both 5' and 3' junctions by next-generation sequencing. The protocol can be adapted to other neuronal proteins by redesigning the guide RNA and donor sequence, and supports fluorescent proteins as well as epitope and self-labeling tags. The plasma membrane marker can also be replaced with other fluorescent reporters or markers for intracellular organelles to assess infection efficiency and verify subcellular localization of the protein of interest. The full workflow takes 5-6 weeks. © 2026 The Author(s). Current Protocols published by Wiley Periodicals LLC.

abstract = {Expanded CAG/CTG repeats cause more than 15 different diseases that all remain without a disease-modifying treatment. Because repeat length accounts for most of the variation in disease severity, contracting CAG/CTG repeats presents an attractive therapeutic avenue. Here, we show that the CRISPR-Cas9 nickase targeted to CAG/CTG repeats leads to efficient repeat contractions in Huntington's disease (HD) patient-derived neurons and astrocytes and in myotonic dystrophy type 1 patient-derived neurons. The approach was allele selective and free of detectable off-target mutations. Injection of the Cas9 nickase into the striatum of the R6/1 mouse model of HD using adeno-associated viral vectors led to repeat contractions in more than half of striatal neurons. Upon injection, we observed a reduction in the number of inclusion bodies, an improved gene expression profile, and amelioration of locomotion deficits in the open field test. The effects were greater than expected from the contractions induced, suggesting that non-cell autonomous mechanisms may be involved. Our results provide the proof of concept that correction of CAG/CTG repeats can improve HD phenotypes in a mouse disease model.},

However, whether other counter-CRISPR mechanisms exist remains unexplored. Here, we report a phage-encoded two-protein system, termed Healer, which neutralizes CRISPR immunity via a post-cleavage DNA repair mechanism. This phage replication-associated system comprises two proteins: Gp63 (a DUF669 domain-containing protein), and Gp64 (an AAA domain-containing protein). Mechanistic investigations elucidate that Gp63 acts as a rapid-response effector of CRISPR-induced DNA breaks. After Gp63 binds ssDNA, it promotes Gp64-mediated homologous recombination, which repairs CRISPR-generated phage DNA breaks and supports phage viability. Notably, co-expression of the Healer system with Cas9/Cas12 in E. coli, P. aeruginosa, and A. baumannii demonstrated high phage genome-editing efficiency. Collectively, our findings reveal an important anti-CRISPR complementary strategy, providing a promising tool for genome engineering.},

abstract = {INTRODUCTION: Glycogen is a universal carbon and energy reserve that plays crucial roles in fungal stress adaptation, cellular homeostasis, and predatory activity. However, the role of glycogen metabolism in nematode-trapping fungi has largely remained unexplored. Here, we performed a systematic functional characterization of AfGsy2, the glycogen synthase-encoding gene in the biocontrol fungus Arthrobotrys flagrans.

METHODS: Using a CRISPR-Cas9-mediated deletion mutant, together with overexpression and complementation strains, we investigated the involvement of AfGsy2 in mycelial growth, stress tolerance, trap formation, nematicidal activity against Caenorhabditis elegans, chlamydospore production and germination, and glycogen accumulation. Subcellular localization was examined using an AfGsy2-GFP fusion protein.

RESULTS: Deletion of AfGsy2 reduced hyphal growth on both nutrient-rich and nutrient-poor media but enhanced tolerance to osmotic, salt, and oxidative stresses, suggesting that blocked glycogen synthesis may trigger metabolic rerouting toward alternative stress-protective compounds. Notably, the ΔAfGsy2 mutants exhibited reduced trap production and nematicidal activity against C. elegans, whereas overexpression of AfGsy2 accelerated these processes, suggesting a link between glycogen metabolism and predatory activity. Moreover, AfGsy2 positively regulated chlamydospore production, glycogen accumulation, and chlamydospore germination. AfGsy2-GFP predominantly localized to the vacuoles of chlamydospores, and complementation restored the mutant phenotypes to wild-type levels.

DISCUSSION: Collectively, these findings uncover a link between glycogen metabolism and growth, stress resilience, sporulation, and predatory activity in A. flagrans, and establish a molecular foundation for the rational improvement of nematode-trapping fungi. Together, these results identify AfGsy2 as a pleiotropic regulator linking glycogen metabolism to biocontrol-related traits.},

abstract = {Brassicaceae crops are globally important economic plants, whose yield and quality directly affect the supply of edible oil and vegetables. Most of these crops are polyploids with complex genomes and numerous homoeologous gene copies, which demand high efficiency and specificity from gene editing tools, while providing ideal models for studying the rules of polyploid genome editing. Traditional breeding methods, such as crossbreeding and mutation breeding, are constrained by long cycles, low efficiency, and poor specificity, making them insufficient for precise genetic improvement. Gene editing technologies, characterized by precision, efficiency, and targeting specific genomic loci, are core tools for crop breeding. Among these, ZFNs and TALENs rely on protein-DNA recognition and are complicated and costly to design; CRISPR-Cas, which achieves precise recognition through base pairing between guide RNA and target DNA, is simple, efficient, and the most widely used editing tool. Base and prime editors enable single-nucleotide substitutions or small fragment insertions without generating double-strand breaks, making them suitable for directed modification of point mutations. This review summarizes the progress of gene editing in Brassicaceae for bolting/flowering, plant architecture, nutritional quality, tolerance to abiotic stresses (temperature, salinity, drought, heavy metals), and resistance to biotic stresses (diseases, pests). We analyze challenges, including off-target effects, difficulties in polyploid genome editing, and imperfect genetic transformation systems, and discuss future directions integrating gene editing with multi-omics and artificial intelligence. This review aims to provide a theoretical basis and technical support for precise molecular breeding of Brassicaceae crops.},

We generated a new GnRH-P2A-iCreERT2-P2A-tdTomato (hereafter referred to as the GnRH-CT-tdT line) knock-in mouse line utilizing CRISPR/Cas9 technology. Characterization analysis of this line revealed that tdTomato expression precisely recapitulates endogenous GnRH expression and iCreERT2 recombines in GnRH neurons with excellent specificity and sensitivity. Therefore, this newly constructed GnRH-CT-tdT mouse line provides a useful tool to perform genetic manipulation in GnRH neurons. As a proof-of-principle, we used this line to investigate the role of Chd7 (Chromodomain helicase DNA-binding protein 7), a gene with its loss-of-function associated with isolated gonadotropin-releasing hormone deficiency (IGD). Surprisingly, ablation of Chd7 in GnRH neurons does not affect the number of GnRH neurons, pubertal onset, and reproductive organ morphology. Therefore, Chd7 is dispensable in GnRH neurons after they have initiated GnRH expression. In summary, the GnRH-CT-tdT mouse line is a valuable tool to study gene function in GnRH neurons and to dissect the pathogenesis of IGD.},

The highly selective and programmable characteristics of CRISPR have enabled its broad application. Recent advances in CRISPR biotechnology have promoted its widespread use in various biomedical fields, such as CRISPR screening. Ongoing preclinical and clinical trials will help determine the full capabilities of CRISPR in disease therapy. The efficacy of CRISPR-based applications is fundamentally dependent on optimized delivery strategies. Multiple approaches for delivering the CRISPR components have been investigated, primarily relying on physical, viral and non-viral delivery methods. Each method has specific strengths and limitations. Notably, non-viral delivery systems hold significant promise for CRISPR applications, offering distinct advantages such as transient expression, low immunogenicity, and fewer size constraints for cargo delivery. Various biomaterials demonstrate strong potential for delivering CRISPR components to achieve gene editing, including inorganic nanoparticles, polymeric nanoparticles, lipid nanoparticles, metal-organic frameworks, DNA origami, and virus-like particles. Therefore, this review provides an overview of recent research on the molecular principles of CRISPR and its biomedical applications. Recent advances in CRISPR-based treatments and their delivery vectors are also reviewed. Finally, the challenges faced by CRISPR technology are discussed.},

Beginning with an adenosine-producing strain, we first knocked-out the apt and adeC genes, which were involved in product degradation pathways, and deleted the purR gene to alleviate the feedback inhibition on purine operon through CRISPR-Cas9 technology. Then, we overexpressed the nucleoside hydrolase RihC, PRPP amidotransferase PurF, and ribokinase RbsK to enhance the de novo adenine biosynthesis and enable the recycling of D-ribose. The production of adenine reached 18 g/L after the fed-batch fermentation, and the titer continued to reach 78 g/L when adenosine was added as the substrate subsequently, revealing the significant catalytic role of RihC produced during the fermentation. This work innovatively integrated de novo biosynthesis and enzymatic conversion strategies to achieve high yield adenine production in Bacillus subtilis, demonstrating a promising scalable process for industrial adenine manufacturing.},

abstract = {Noncoding RNAs, including long noncoding RNAs, enhancer RNAs, circular RNAs, and small nuclear and nucleolar RNAs, represent a major, yet still largely uncharacterized, regulatory layer in the eye. A subset of these molecules, chromatin-associated RNAs (caRNAs), physically interacts with DNA and nuclear protein complexes to influence genome organization, transcriptional output, and stress responses. Although caRNAs have emerged as essential regulators of chromatin topology and gene expression in diverse tissues, their identity, dynamics, and mechanisms in the retina and retinal pigment epithelium (RPE) remain elusive. Recent high-resolution genomic studies, disease transcriptomes, and mechanistic studies implicate dysregulated caRNAs in age-related macular degeneration, glaucoma, and diabetic retinopathy, yet causal chromatin-level functions have rarely been demonstrated. In this review, we summarize current understanding of ncRNA-mediated regulation in vision, highlight emerging evidence for caRNA involvement in retinal development, photoreceptor and RPE specialization, and disease-associated epigenetic remodeling, and outline major mechanistic gaps that must be addressed. We then survey the rapidly expanding CRISPR toolbox, including base and prime editors, CRISPRi/a, Cas13 knockdown and editing platforms, and RNA-recruitment and spatial repositioning systems, that now enable targeted perturbation of both caRNA genomic loci and transcripts. These technologies provide the first practical route to move beyond correlative RNA-chromatin maps toward the mechanistic dissection of how caRNAs organize regulatory hubs, modulate enhancer-promoter communication, and shape long-range genome interactions in the eye. As the catalog of pathogenic noncoding variants grows, the ability to decode and engineer caRNA networks will be central to future precision therapeutic strategies for ocular disorders.},

abstract = {The presence of the potent carcinogen aflatoxin B1 (AFB1) in agricultural products poses a grave threat to food safety and human health, underscoring the imperative development of highly sensitive detection methodologies. Despite the considerable efforts that have been dedicated to aptamer-based biosensors, the sensitivity of typical nucleic acid-integrated aptasensors is still limited by inefficient strand displacement. To address this limitation, a "three-in-one" multireadout lateral flow assay for AFB1 was developed, integrating CRISPR/Cas12a single-stranded DNase activity with PtPdRu nanozyme-mediated colorimetric signal amplification. The detection process initiates with a "locked activator" DNA configuration, wherein aptamer-specific recognition of AFB1 activates the nonspecific ssDNA cleavage activity of CRISPR/Cas12a, resulting in a fluorescence output. The integrated PtPdRu functions as both a colorimetric probe and a peroxidase mimic, allowing for catalytic amplification based on 3,3',5,5'-tetramethylbenzidine for improved colorimetric detection. The signal-amplified aptasensor achieves ultrasensitive detection with a limit of detection of 0.22 pg/mL, which is 13-fold and 2.7-fold lower than those of the fluorescence mode and the intrinsic colorimetric mode, respectively. Coupled with a smartphone app, the "samples‑in, signal‑out" strategy exhibits high specificity in moldy corn and peanut samples. The triple-modal outputs provide a versatile tool for sensitive detection of AFB1 in agricultural products.},

abstract = {Early screening and timely treatment of bladder cancer are crucial to improving patient survival rates. However, the lack of sensitive and noninvasive diagnostic approaches remains a major challenge. Herein, we developed an electrochemical biosensor for urinary miRNA-182 in bladder cancer detection based on the primer exchange reaction (PER) and CRISPR/Cas12a one-pot cascade reaction. Specifically, the presence of the target miRNA-182 initiated the PER reaction to generate multiple CRISPR/Cas12a activation sequences, which subsequently activated the trans-cleavage activity of CRISPR/Cas12a and induced the cleavage of methylene-blue-labeled signal probes (SP-MB). The uncleaved SP-MB was captured by the complementary sequence (CS) immobilized on the electrode surface, generating an electrochemical response signal that decreased with increasing target concentration, thereby enabling the quantitative detection of miRNA-182. Notably, the detection performance of biosensors constructed on different DNA nanostructure-modified interfaces (S, H, TDN, and TDR) containing CS was systematically compared to elucidate the regulatory mechanism of the biosensing interface. The optimized interface significantly improved the dynamic detection range, with a low detection limit of 1.60 pM. This study not only provides a promising noninvasive diagnostic strategy for bladder cancer but also provides fundamental insights into the rational design of DNA nanostructure-based biosensing interfaces for high-performance electrochemical biosensors.},

abstract = {Accurate and rapid detection of RNA biomarkers is crucial for early disease diagnosis and infectious disease management. Although RT-qPCR remains the gold standard, its utility for point-of-care testing is limited by run-to-run variability and dependence on specialized instrumentation. Conversely, colorimetric assays offer operational simplicity but generally fall short of the sensitivity and specificity demanded for reliable applications. To bridge this gap, we present an innovative cut-and-bind colorimetric RNA detection platform that synergistically integrates the sequence-specific programmable cleavage fidelity of CRISPR/Cas12a with zinc finger protein-mediated gold nanoparticle assembly (termed CasFinger-Gold). Strategically engineered ssDNA-dsDNA hybrid overhang probes sharpened target discrimination while minimizing off-target background, ensuring robust readouts within complex biological matrices. When coupled with reverse transcription-recombinase polymerase amplification, the CasFinger-Gold system achieved visually interpretable RNA detection with a limit of detection of 1.8 × 103 copies μL-1 for HCoV-OC43 viral RNA and 0.4 ng total RNA μL-1 for the long non-coding RNA PCA3. The platform further enabled direct, rapid (<120 min), purification-free PCA3 detection from cell-derived extracellular vesicles (EVs) at clinically relevant vesicle inputs (down to ∼106 EVs μL-1). Notably, no cross-reactivity was observed against four phylogenetically distinct respiratory viruses or in PCA3-negative cell lines. By delivering instrument-free visual readouts comparable to RT-qPCR, CasFinger-Gold represents a versatile diagnostic modality poised to expand the molecular diagnostic toolbox toward accessible point-of-care solutions.},

abstract = {Timely and reliable identification of bacterial infections in emergency settings remains a major challenge. To address this challenge, here we utilized CRISPR/dCas9-mediated self-assembly to develop a colorimetric and Raman dual-mode biosensor (referred to as dCARD) and applied it to point-of-care bacterial detection. Briefly, dCARD utilized the CRISPR/dCas9-mediated precise recognition of target amplicons to build bridges, attaching gold nanoparticle (GNP)-probe loaded with 4-aminothiophenol (4-ATP) onto the surface of GNP-streptavidin (GNP-SA). The dispersion-to-aggregation change of particles triggered a significant color change from red to purple, along with the formation of Raman hotspots. As a result, the presence of target bacteria was translated into cross-validated color and Raman signals, showcasing high reliability. This biosensor not only maintained the simplicity of visual readout but also integrated the quantitative function of a portable Raman spectrometer, allowing operators to flexibly switch signal modes in different scenarios. The specific primer-based isothermal amplification and CRISPR/dCas9-mediated precise recognition of amplicons together improved the specificity of dCARD, enabling accurate detection of the target bacteria down to about 10 CFU/mL without interference from non-target bacteria. By using a simplified preprocessing strategy, the assay time could be further reduced to less than 30 min. The robustness and programmability of dCARD were also demonstrated by detecting three common bacteria in real urine specimens. We expect this biosensor to evolve into a universal and field-deployable screening tool for bacterial infections.},

abstract = {The multiplex detection of nucleic acid biomarkers, including circulating tumor DNAs (ctDNAs) and microRNAs (miRNAs), holds promise for improving the accuracy of molecular diagnostic techniques. In this study, we developed a CRISPR/Cas9-based sensing platform capable of simultaneously detecting multiple nucleic acid biomarkers. This approach leverages the activation of the CRISPR/Cas9 system through the generation of monomeric substrates mediated by rolling circle amplification (RCA). Specifically, upon the presence of a specific target, the RCA process is initiated, producing concatemeric DNA products. By incorporating an endonuclease and complementary reporter molecules, the RCA products are cleaved into monomeric substrates. Subsequently, Cas9/sgRNA complexes recognize and bind these monomeric substrates, activating the CRISPR/Cas9 systems, which further cleave the substrates to produce amplified fluorescence signals. Compared to conventional RCA methods, which often suffer from product aggregation, the monomeric substrate generation strategy demonstrated enhanced sensing capabilities and analytical performance, with signal intensities nearly double those observed in traditional approaches. To enable multiplex detection, three distinct sets of padlock probes, reporter molecules, and sgRNAs were designed to selectively target three different nucleic acid sequences. The platform exhibited high sensitivity and simultaneous detection of multiple ctDNAs and miRNAs, achieving limits of detection (LODs) ranging from 1.28 fM to 1.50 fM for ctDNAs and 0.61 fM to 0.97 fM for miRNAs. Additionally, analyses of clinical serum samples confirmed the method's accuracy and applicability within complex biological matrices. Collectively, this work introduces a multiplex nucleic acid biomarker detection platform with significant potential for advancing molecular sensing and clinical diagnostic applications.},

abstract = {Achieving precise control over CRISPR-Cas12a activity remains a fundamental challenge in the development of versatile sensing platforms, particularly for applications in diagnostics. Herein, we report an allosteric strategy that employs modular loop-engineered hairpin (MLEH) to precisely control Cas12a activation, thereby establishing a plug-and-play sensing framework with enhanced versatility. The MLEH comprises both the loop‑embedded ssDNA activator sequence and its complementary blocking domain. The input-triggered linearization of the MLEH via toehold-mediated strand displacement governs the accessibility of the activator, thereby controlling the binding and activation of Cas12a. A distinct advantage of this strategy is its elimination of the reliance on protospacer adjacent motif (PAM) sequences, customized CRISPR RNA (crRNA), or external activators. By merely substituting the responsive region of the MLEH, the system can be flexibly reconfigured to detect a wide range of targets, encompassing nucleic acids, proteins, and small molecules. MLEH-Cas12a broadens the scope of CRISPR technologies, offering a robust tool for diverse diagnostic applications. Collectively, our work delineates a novel allosteric regulatory mechanism for Cas12a activation and highlights the potential of engineered hairpins as key components in next-generation molecular sensing platforms, overcoming current limitations in CRISPR-based diagnostics and enabling broader target detection.},

abstract = {Most existing CRISPR/Cas12a methods for small molecules detection employ DNA aptamers as an intermediary, while RNA aptamers remain underexplored. The conventional CRISPR/Cas12 system offers limited programmability due to its partially conserved crRNA sequence. In this study, we developed an aptamer-regulated CRISPR/Cas12a system based on split crRNA. We divided the full crRNA into a crRNA handle segment (RH) and a crRNA spacer segment that is identical to the RNA aptamer sequence of target (RS-Apt). RS-Apt was endowed with dual functions: activating the activity of Cas12a and binding to target small molecules, ingeniously linking non-nucleic acid targets with the CRISPR system. The strong affinity between the target and RS-Apt reduces the amount of RS-Apt available to participate in the CRISPR system, resulting in a decrease in the fluorescence signal of the system. Within 1.5 h, the system for theophylline (TP) exhibited a linear range from 50 nM to 200 µM and a detection limit (LOD) of 2 nM, while the system for tobramycin (TOB) showed a linear range of 200 nM to 100 µM with an LOD of 63 nM. Notably, visual semi-quantitative detection of TP and TOB was achieved via lateral flow strips. Moreover, the system achieved satisfactory recovery and visual detection of TP using lateral flow strips in TP-spiked serum samples. This system can detect different targets simply by changing the sequence of the RS-Apt and activator, without the need for complex sequence design of the chains or large-scale instruments, providing a new strategy for CRISPR/Cas12a in the detection of small molecules.},

The electrode-modification steps were evaluated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The impedance response increased linearly with miR-331-5p concentration over the experimentally evaluated range of 5-400 pM. The limit of detection and limit of quantification were 7.82 and 23.71 pM, respectively. Responses to the non-target miRNAs miR-146a-5p, miR-19 b-3p, miR-24-3p, and miR-7-5p were substantially lower than the response to miR-331-5p. Triplicate spike-recovery measurements in healthy human serum and storage-stability studies supported the analytical applicability and reproducibility of the platform. These findings demonstrate a CRISPR-dCas13a/EIS-based proof-of-concept analytical platform for miR-331-5p detection. Validation in well-characterized clinical cohorts will be required before any diagnostic application can be established.},

abstract = {BACKGROUND: Triphenyl phosphate (TPP), a ubiquitous organophosphate flame retardant and plasticiser, has emerged as a pervasive environmental contaminant with suspected endocrine-disrupting properties.

METHODS: In this study, we employed an integrated approach combining epigenetic CRISPR-Cas9 knockout screening, spatial transcriptomics, and metabolic flux analysis to explore the response of glioma cells to in vitro exposure to a nominal TPP concentration of 11 μM. Targeted cellular, biochemical, promoter-occupancy and signalling assays were performed.

RESULTS: TPP exposure was associated with changes in several cellular readouts in glioma cells, including a higher CCK-8 signal, differences in MMP secretion, Rac1 activity and matrix adhesion and differences in glucose, lactate and mitochondrial-respiration readouts. TPP exposure was also associated with increased BRG1 occupancy at the assayed epidermal growth factor receptor (EGFR) promoter region, together with higher EGFR- and epiregulin (EREG)-related readouts. This pattern is consistent with a candidate EREG-EGFR/MAPK-ERK pathway association but does not prove a self-sustaining loop or direct chemical recruitment. Spatial transcriptomic analysis described regional heterogeneity in mitochondrial-gene expression within public glioblastoma tissue.

CONCLUSION: Our findings support a candidate BRG1-associated cellular framework in which nominal TPP exposure is associated with BRG1-related chromatin and EGFR/metabolic readouts in glioma cells.},

abstract = {This review focuses on the critical role of CDPKs in advancing plant immunity research, highlighting how their functions can uncover key defence mechanisms and bridge critical knowledge gaps in the field. Calcium serves as the cornerstone of immune signalling, propagating pathogen-induced signals through specific sensors and decoders. Among these, calcium-dependent protein kinases (CDPKs) stand out as plant-specific signal transducers, directly converting calcium fluxes into defence activation. By modulating key immune components, CDPKs act as key hubs in plant immunity. Deciphering their role and crosstalks with other signalling networks is crucial for understanding the complexities of plant defence mechanisms. Although functional redundancy and extensive crosstalk among CDPK family members have historically hindered precise functional characterization, these features also highlight the robustness and adaptability of plant immune systems. Recent advances including high-throughput transcriptomics, comprehensive CDPK family-wide analyses, and multiplex genome-editing approaches such as CRISPR-Cas-based multi-gene targeting are now enabling finer functional resolution of CDPK members within complex multigene families. This review synthesizes current insights into CDPK-mediated signal transduction, with particular emphasis on their roles in coordinating defence responses and integrating with major signalling pathways, including mitogen-activated protein kinase (MAPK) cascades, reactive oxygen species (ROS) signalling, and WRKY transcription factor-mediated gene regulation. Importantly, the continued development of integrative and high-resolution approaches is poised to overcome longstanding limitations in the field, facilitating deeper dissection of CDPK-specific functions. Collectively, these advances position CDPK research at the forefront of plant immunity studies, with strong potential to reveal novel regulatory mechanisms.},

abstract = {Infant neuroblastoma (NB), defined by diagnosis during the first year of life, represents a clinically heterogeneous disease spectrum ranging from localized tumours with favourable outcomes and a capacity for spontaneous regression, to high-risk metastatic disease requiring intensive multimodal therapy. In infants, treatment intensity is determined by disease stage, tumor biology, MYCN status, risk classification, symptoms, response to therapy, and metastatic involvement, particularly relevant to high-risk disease, consequently the potential toxicity of intensive treatment is specific to high-risk disease, as compared to favorable risk tumors which can be managed with surgery, reduced frequency techniques, or observations. Important determinations of neuroblastoma biology and prognosis are genetic alterations involving MYCN and ALK, but the predominately investigated field with therapeutic feasibility of targeting these changes with CRISPR/Cas9 is in preclinical neuroblastoma models rather than in infants. An investigational hypothesis is accordingly considered by their potential relevance to infant neuroblastoma rather than an established clinical application. The safe and efficient in vivo delivery of CRISPR/Cas9 components remains a major challenge, owing to cargo size, immunogenicity, and degradation, particularly within the delicate physiological environment of infants. This review emphasises the need for advanced delivery systems, focusing on the potential of nanoparticle-mediated approaches. Emerging preclinical findings support the feasibility of nanoparticle-mediated CRISPR/Cas9 delivery, although direct evidence in infant neuroblastoma remains limited. Importantly, the evidence for nanoparticle-mediated CRISPR/Cas9 therapy remains largely preclinical. Studies performed in general neuroblastoma models, non-cancer models, or adult cancers should not be interpreted as direct evidence of efficacy in infant neuroblastoma.},

abstract = {Fluorogenic RNA aptamers have emerged as powerful molecular tools for cancer imaging, biosensing, and biomarker detection due to their high specificity, low background fluorescence, and genetic encodability. These short RNA molecules activate fluorescence upon binding specific fluorogens, enabling real-time visualization of intracellular targets and dynamic molecular processes in living systems. Recent advances in RNA structural engineering, fluorophore optimization, and biosensor integration have significantly expanded the translational applications of fluorogenic aptamers in oncology. This mini-review summarizes the structural principles, fluorescence activation mechanisms, and cancer-related applications of fluorogenic RNA aptamers and related nucleic acid biosensors. Foundational studies describing the architecture of fluorogenic aptamer families, including Spinach, Broccoli, Mango, Pepper, Squash, and Beetroot, are discussed with emphasis on G-quadruplex-mediated fluorogen stabilization and fluorescence enhancement. Furthermore, recent developments in CRISPR/Cas-assisted fluorogenic biosensors, dual-color RNA imaging systems, fluorogenic DNAzymes, and amplification-driven aptamer platforms are highlighted. Direct applications across multiple malignancies, including brain, breast, colorectal, liver, lung, prostate, and skin cancers, demonstrate the growing utility of these technologies for tumor-associated RNA detection, epigenetic biomarker analysis, molecular imaging, and therapeutic monitoring. In addition, advances in fluorescence brightness, structural stability, and multiplex imaging strategies have improved the sensitivity and adaptability of fluorogenic RNA systems for complex biological environments. Despite current limitations related to RNA stability, intracellular delivery, and tissue penetration, fluorogenic RNA aptamers represent highly promising tools for next-generation precision oncology. Continued integration with nanotechnology, live-cell imaging, artificial intelligence, and molecular diagnostics is expected to enhance further their clinical and translational potential in cancer research and personalized medicine.},

abstract = {In this study, we sought to comprehensively map ubiquitin signaling networks at the crossroads of cellular proliferation and proteostasis, both crucial in cancer. Genome-wide CRISPR knockout screening in the presence of the ubiquitin E1 inhibitor TAK-243 identified 239 genes whose ablation sensitizes cells to ubiquitination blockade. Follow-up studies reveal a role for the nuclear protein, C16orf72/HECT, UBA, and WWE domain containing E3 ubiquitin protein ligase 1 (HUWE1)-Associated Protein modifying Stress Responses (HAPSTR1), in chromatin proteostasis and DNA replication. We show that HAPSTR1 recruits the E3 ligase HUWE1 to the chromatin, keeping the chromatin-associated proteome in check, and is itself turned over by HUWE1 during cell cycle progression. Structural modeling of the HAPSTR1/HUWE1 complex, supported by mutational analysis, demonstrates that loss of HUWE1 binding renders HAPSTR1 unable to support cellular proliferation when ubiquitin signaling is suppressed. Consequently, HAPSTR1 ablation impairs clearance of chromatin-associated proteins, triggering global transcriptional and proteostatic adaptations. Under diminished ubiquitin signaling, these adaptive mechanisms give way to replication stress and premature S phase entry, culminating in cell cycle collapse and DNA damage. Our findings uncover protein networks exhibiting synthetic lethality with ubiquitin signaling blockade and highlight vulnerabilities of actively proliferating cells to proteostatic imbalance at the chromatin.},

abstract = {Oncogenic gene fusions are key drivers of cancer, yet most remain undruggable by current therapies. Here, we establish CRISPR-PspCas13b as a personalizable platform for systematic silencing of various fusion transcripts. We reveal that recognition and cleavage of the breakpoint sequence by PspCas13b disrupt the fusion transcript, resulting in efficient protein depletion. PspCas13b cleavage produces aberrant, translation-incompetent target RNA species, a subset of which harbors internal deletions proximal to the cleavage site. We demonstrate that targeting the BCR::ABL1 breakpoint sequence efficiently degrades both wild-type and drug-resistant BCR::ABL1 mutants, which are the primary drivers of tyrosine kinase inhibitor resistance and relapse in chronic myeloid leukemia. Molecular profiling revealed that PspCas13b impairs BCR::ABL1 tyrosine phosphokinase activity and triggers extensive transcriptomic and proteomic remodeling, leading to erythroid differentiation and apoptosis in drug-resistant cells. Beyond BCR::ABL1, personalized design of PspCas13b effectively silences other undruggable oncogenic fusions. Collectively, this study establishes a molecular framework for precise targeting of undruggable or drug-resistant oncogenic transcripts.},

abstract = {Rolling circle amplification (RCA) is a powerful nucleic acid amplification strategy, yet conventional RCA-based biosensing often relies on target-specific padlock probes for circular template construction, which increases probe-design complexity and may introduce nonspecific ligation and background amplification. Here, we develop a padlock-free RCA strategy for CRISPR-based pathogen detection through primer-programmed circular template generation (PPCTG) strategy. Asymmetric recombinase polymerase amplification (RPA) with rationally designed phosphorylated primers generates target-derived single-stranded DNA (ssDNA), which subsequently undergoes universal splint-mediated circularization to form amplification templates without target-specific padlock probes. By integrating target recognition into the amplification-derived ssDNA intermediate, PPCTG couples target amplification with circular template generation while simplifying probe design and reducing nonspecific background. The resulting circular templates support continuous RCA, generating long ssDNA scaffolds that provide abundant activator sites for CRISPR-Cas12a, thereby enabling cascaded signal amplification through trans-cleavage of fluorophore-quencher reporters. The platform achieved a limit of detection of 3.47 aM for Staphylococcus aureus with high analytical specificity. Moreover, extraction-free detection was demonstrated in crude sputum and exhaled breath condensate, with recovery rates of 96.4%-105.5% and good agreement with qPCR results. Overall, PPCTG provides a padlock-free strategy for programmable circular template generation and integrates target amplification, RCA, and CRISPR-Cas12a signal amplification into a streamlined workflow, offering a low-background and ultrasensitive approach for pathogen detection in complex biological matrices.},

abstract = {CRISPR-dCas9 epigenome editing represents a paradigm shift from static DNA sequence editing to dynamic reprogramming of gene expression, offering a powerful and precise toolbox with the potential to develop stable and climate-resilient crops without altering DNA sequences. The escalating challenges of global food security, driven by climate change and population growth, necessitate innovative crop improvement strategies that extend beyond conventional breeding. Although CRISPR-Cas9 has revolutionized plant biotechnology through direct genome editing, CRISPR-based epigenome editing has emerged as a new frontier. By repurposing nuclease-dead Cas9 as a programmable targeting platform fused to epigenetic effector domains, researchers can precisely modulate gene expression without altering the DNA sequence. This approach has already yielded compelling successes, such as the engineering of durable resistance to cassava bacterial blight through targeted epigenetic silencing of a susceptibility gene. This review focuses primarily on the current state of CRISPR-based epigenome editing systems, including acetyltransferases, demethylases, DNA methyltransferases, and deacetylases, and their applications in crop improvement research. We critically evaluate their mechanisms in rewriting epigenetic regulatory information, their demonstrated efficacy in enhancing yield components, disease resistance, and abiotic stress tolerance, and their potential to create stable meiotically heritable epialleles, although most demonstrations remain at the proof-of-concept stage in model plants, with field validation in major crops still limited. This review provides a balanced analysis of key challenges, including editing specificity, context-dependency, delivery limitations, and regulatory considerations. Finally, we outline future directions focusing on technological refinement, multi-omics integration, and field validation. Epigenome editing shows promise as a conceptually distinct and transformative approach in crop biotechnology, through targeted modulation of a plant's epigenetic landscape. However, its full potential hinges on overcoming challenges related to stability, predictability, and field-scale validation.},

abstract = {Phage therapy represents a promising strategy against multidrug-resistant bacteria, but its clinical effectiveness is increasingly compromised by the emergence of phage-resistant traits (PRTs). This resistance develops through multiple interconnected mechanisms that operate at different levels of bacterial defense. At the primary level, mutations in phage receptors, cell surface glycoconjugates (lipopolysaccharide, capsule polysaccharide, exopolysaccharide), outer membrane proteins, drug efflux pumps, and surface layer proteins provide the first line of defense by preventing phage adsorption. These receptors are highly diverse across Gram-negative bacteria, Gram-positive bacteria, and acid-fast bacteria, with PRT being particularly dominant in Gram-negative species. At the secondary level, bacteria deploy sophisticated antiphage defense (APD) systems, including CRISPR-Cas, restriction-modification systems, and abortive infection mechanisms. The recent discovery of over 150 distinct APD systems underscores the remarkable complexity of bacterial immunity. Concurrently, bacteriophages have evolved anti-antiphage defense (AAPD) systems to counter bacterial immunity, establishing a dynamic coevolutionary arms race. This continuous interplay between APD diversification and AAPD counteradaptation drives the rapid emergence of PRT, which threatens the long-term viability of phage therapy. This systematic review examines the molecular basis of phage resistance across diverse bacterial taxa, analyzes the evolutionary and coevolutionary forces shaping APD and AAPD systems, and highlights previously overlooked aspects of phage-bacteria interactions. By integrating these perspectives, we aim to inform strategies for advancing modern phage therapy and guiding future research directions.},

abstract = {Clinical use of CRISPR-Cas proteins for genome engineering is constrained by their large size, limiting in vivo delivery. To address this, we engineered an ultracompact and versatile platform from a minimally active, 400-amino acid Cas12f protein from Blautia lenta. A multi-stage strategy of structure-guided protein mutagenesis and systematic single guide RNA (sgRNA) optimization transformed BlCas12f into a "CasNano" as a potent genome targeting tool for mammalian cells. When a catalytically dead CasNano (dCasNano) is fused to a VPR domain, it activates endogenous genes with an efficiency and specificity comparable or superior to the benchmark SpCas9 system for the guide RNAs (gRNAs) and loci tested under equal-mass plasmid transfection; as editor expression was not quantified and stoichiometric differences would, in any case, preclude equivalent normalization, these comparisons describe functional output rather than intrinsic activity. We established the platform's versatility for bidirectional epigenetic editing by fusing dCasNano to a DNA methyltransferase (DNMT3A) for gene silencing or a dioxygenase (TET1) for gene activation. TET1-mediated reactivation persisted for 5 months in human embryonic stem cells (hESCs), whereas DNMT3A-deposited methylation was not retained at 2 weeks in a dividing reporter line. CasNano's small size and distinct CCN PAM sequence highlight its potential for future therapeutic applications constrained by viral delivery cargo capacity.},

Given the increasing number of different aptamer-CRISPR/Cas systems developed recently, particularly for infectious diseases, we provide a comprehensive overview of these platforms designed for detecting significant viruses such as SARS-CoV-2, Monkeypox virus, Hepatitis B virus and bacteria that include Mycobacterium tuberculosis, Staphylococcus aureus and Salmonella. Current challenges that impede the deployment of aptamer-CRISPR/Cas for point-of-care pathogen detection were also mapped, including primary barriers such as clinical matrix effect and stability. Several strategies to mitigate these issues were also set forth, predominantly the integration of artificial intelligence and machine learning to accelerate the transition of aptamer-CRISPR/Cas system to the clinical translation and commercialization phase, paving the way towards widespread implementation in global health.},

Leveraging the programmable precision of CRISPR/Cas12b system, which has significantly advanced the field of molecular diagnostics, we developed a rapid, high-sensitivity assay for the dual detection of HTNV and SEOV. Each virus was detected in a separate, target-specific single-tube reaction. The assay combines recombinase polymerase amplification (RPA) with CRISPR/Cas12b-mediated fluorescence detection and uses virus-specific sgRNAs and RPA primers targeting conserved genomic regions. Using recombinant plasmid standards, both targets were detected at 1 × 10[1] copies/test in three technical replicates; this is a preliminary analytical detection threshold and does not incorporate extraction losses or matrix-associated inhibition. No cross-reactivity was observed within the evaluated four-organism non-target panel. In a preliminary feasibility assessment, all nine RT-qPCR-positive rodent samples (seven HTNV and two SEOV) were positive by the RPA-CRISPR/Cas12b assay, indicating complete positive agreement in this all-positive sample set. Because no negative samples were included, negative agreement, diagnostic specificity, false-positive rate, and overall clinical diagnostic accuracy could not be assessed. These results support further development of the assay as a potential screening tool; larger studies using well-characterized positive and negative clinical or field specimens are required.},

Conventional methods, including viral culture, immunological assays, and reverse-transcription real-time quantitative PCR (RT-qPCR), provide important diagnostic benchmarks but are constrained by long turnaround times, dependence on specialized equipment, or reduced sensitivity in low-viral-load specimens. This review summarizes recent advances in influenza virus detection, with emphasis on molecular diagnostics, biosensors, point-of-care testing, and high-throughput sequencing. Digital PCR offers precise absolute quantification, whereas isothermal amplification technologies such as reverse transcription loop-mediated isothermal amplification (RT-LAMP) and reverse transcription recombinase polymerase amplification (RT-RPA) reduce reliance on thermal cycling and support portable testing. CRISPR-Cas systems further improve sequence specificity and are increasingly being integrated with isothermal amplification, lateral-flow readouts, and microfluidic platforms. Biosensor strategies based on optical, electrochemical, multimodal, and smartphone-assisted readouts provide promising routes for rapid, multiplexed, and point-of-care detection, although standardization and large-scale clinical validation remain key barriers. High-throughput sequencing complements rapid testing by enabling viral typing, variant monitoring, and emerging-pathogen monitoring. Overall, future influenza diagnostics are expected to move toward integrated, low-cost, "sample-in, answer-out" systems that combine sensitivity, speed, portability, and surveillance connectivity.},

Its toolkit now spans genome resources, efficient nuclear transformation, homologous recombination, CRISPR/Cas editing, marker recycling, defined integration sites, and modular multigene assembly. Researchers have used these capabilities to alter carbon allocation, triacylglycerol accumulation, EPA synthesis and lipid-class partitioning, carotenoid metabolism, recombinant-protein production, specialty-metabolite formation, and cultivation robustness. This review assesses whether these advances are sufficient to support Nannochloropsis as a predictable, reusable, and process-aware chassis. The evidence shows that the genus has moved beyond basic transformability. Targeted genome modification and pathway construction are feasible, and native and non-native products have reached biologically relevant and, in some cases, process-relevant levels. However, outcomes remain strongly influenced by genomic locus, strain background, intracellular compartment, physiological state, and cultivation regime. Platform maturation will therefore depend on reusable genomic architectures, reliable organelle-targeting rules, dynamic regulation, and phenotyping suited to iterative design-build-test-learn workflows. Strain design must also be coupled more closely to cultivation, harvesting, product recovery, and deployment. Product-specific chassis configurations are likely to be more practical than a universal strain for EPA-rich oils, pigments, recombinant products, and specialty metabolites. Nannochloropsis thus provides a useful test of how an industrially relevant, non-model photosynthetic eukaryote can become a more designable marine production host.},

CheckM2 estimated 99.99% genome completeness and 0.5% contamination, whereas BUSCO recovered 99.2% of the conserved bacterial single-copy orthologs. Annotation with Prokka v1.15.6 identified 1,897 protein-coding sequences, 52 tRNA genes, four rRNA genes, and one tmRNA. Genome-based phylogenetic and digital DNA-DNA hybridization analyses supported the assignment of strain AP1 to P. acidilactici. Functional annotations generated using Prokka, RAST, eggNOG-mapper, and InterProScan indicated genes putatively associated with carbohydrate fermentation, stress adaptation, exopolysaccharide biosynthesis, peptide transport and proteolysis, cell-surface interactions, and CRISPR-Cas defense. Gene-based functional assignments represent predictions and require experimental validation.

These methods are compared in terms of regulatory levels, technical advantages, limitations, and suitable applications. Together, these tools cover multiple layers of regulation, ranging from transcriptional and post-transcriptional control to protein-level manipulation, and provide powerful approaches for developmental biology, aging, inter-tissue signaling, and disease models, while also establishing a methodological foundation for dissecting cell-autonomous and non-cell-autonomous regulatory mechanisms in complex biological processes.},

abstract = {BACKGROUND: Adult stem cell-derived organoids are invaluable tools for disease modeling and translational medicine owing to their tissue-specific correspondence. However, their complex three-dimensional structure and low genome-editing efficiency have posed significant challenges for functional genetic studies. To address these limitations, this study aimed to establish porcine lung organoid (PLOs) and to develop a robust, high-efficiency genome-editing platform by leveraging the high physiological and anatomical similarity between pigs and humans.

METHODS: PLOs were derived from lung tissues and characterized by immunofluorescence and immunohistochemistry analysis. To enhance genome-editing efficiency using CRISPR/Cas9 and prime editing, a GFP-guided enrichment strategy was used by co-targeting a GFP transgene and endogenous loci, followed by the selection of GFP-negative organoids. Clonal expansion from single organoids was performed to generate genetically homogenous lines. Genetic modifications were validated through cDNA sequencing and western blot analysis. Structural integrity was assessed using AlphaFold2 modeling, and functional changes were evaluated using the forskolin-induced swelling assay.

RESULTS: The established PLOs exhibited sustained self-renewal capacity and expression of surfactant protein C alongside both proximal epithelial and mesenchymal markers, reflecting a composite lung organoid identity. GFP-guided enrichment significantly enriched edited cells; the mutation ratio in the GFP-negative group was significantly higher than that in the GFP-positive group. This system successfully generated fully gene-edited clones with high genetic homogeneity, and effectively enriched for precisely edited organoids, even when applying complex modalities such as prime editing.

CONCLUSIONS: The PLOs and genome-editing platform developed in this study provide a powerful resource for translational medicine. By enabling precise genetic manipulation in a model that closely mimics human lung physiology, this system offers an essential platform for recapitulating human lung pathologies, studying zoonotic infectious diseases, and validating the efficacy of gene therapies.},

abstract = {Plant adaptation to drought, salinity, temperature extremes, pathogens, and herbivorous insects depends on coordinated hormone signalling, transcriptional control, and metabolic reprogramming. The jasmonic acid (JA) pathway is a major regulator of defence and the growth-defence trade-off, and the bHLH transcription factor MYC2 is a central node in JA output. Mechanistically, MYC2 is controlled through demonstrated protein-protein interactions with JAZ repressors, MED25, and selected transcriptional or chromatin regulators; it binds G-box-related cis-elements to regulate specific promoters, whereas many reported links to LOX/AOS, CBF, and antioxidant pathways are transcriptional or pathway-level rather than physical interactions. This integrative narrative review compares MYC2 orthologues across species, distinguishes MYC2-specific functions from those shared with MYC3/MYC4 or other clade IIIe bHLHs, and organises beneficial and detrimental stress phenotypes around pathogen lifestyle, target-gene polarity, tissue and developmental context, paralogue redundancy, and experimental design. We integrate genome-wide DNA-binding, transcriptomic, metabolomic, and protein-level studies, and critically evaluate demonstrated versus prospective applications of CRISPR/Cas genome editing. The synthesis identifies regulatory strategies that may exploit MYC2 networks whilst limiting growth, defence, and quality trade-offs.},

In recent years, it has become clear that biofilm development is a highly orchestrated and dynamic process, controlled by complex genetic networks, transcriptional regulators, two-component systems (TCSs), and environmental signals. The present review covers the molecular mechanisms involved in the initiation, maturation, maintenance, and dispersal of biofilms in general, and in particular, the coordinated functions of adhesins, the icaADBC operon, components of the extracellular matrix (ECM), global regulators (agr, sarA, and sigB), and two-component regulatory systems, as well as emerging insights from transcriptomic studies on biofilm adaptation. We then review the roles of these regulatory pathways in metabolic heterogeneity, antibiotic tolerance, immune evasion, and persistence in clinically relevant biofilm-associated infections, including infective endocarditis, osteomyelitis, prosthetic joint infection, catheter-associated infection, and diabetic foot infection. The review further outlines the latest developments in antibiofilm therapeutics, including matrix-degrading enzymes, quorum-sensing inhibitors, antimicrobial peptides, bacteriophage-based therapeutics, lysins, nitric oxide donors, nanoparticle-assisted therapeutics, and CRISPR-Cas-based antimicrobials. Incorporating molecular regulation into infection-specific pathogenesis and emerging therapeutic strategies, this review offers a new perspective on the biology of S. aureus biofilms and highlights opportunities to develop mechanism-based interventions to combat chronic biofilm-associated infections.},

CRISPR-Cas systems, while best known for their role in bacterial adaptive immunity, also shape bacterial physiology and host-microbe interactions, yet their influence on gastrointestinal carcinogenesis is poorly understood. This review brings together current evidence on the functions of CRISPR-Cas systems in H. pylori and the gut microbiota, highlighting their potential impact on cancer risk, diagnostics, and therapy. Key themes synthesized in this review include their role in bacterial immunity, contributions to microbial imbalance and virulence regulation, and emerging applications in cancer detection, microbiome modulation, and precision oncology. CRISPR profiles are being explored as biomarkers, while engineered systems show promise in targeted editing, phage therapy, and highly sensitive diagnostic platforms such as Cas12a-based assays. Despite this progress, challenges remain, including the risk of off-target effects, technical difficulties in detecting CRISPR signatures within complex microbial communities, and a lack of longitudinal human studies.

abstract = {Conventional and transgenic approaches to crop improvement are increasingly constrained by biosafety concerns, stringent regulatory frameworks, and limited public acceptance, necessitating new precision breeding methods. DNA-free genome editing using the CRISPR/Cas9 approach has emerged as a transformative approach that enables precise, targeted genetic modifications without the stable integration of a foreign gene (transgene). This strategy transiently introduces CRISPR/Cas9 ribonucleoprotein (RNP) complexes, or in vitro transcribed mRNA, into plant cells. This review focuses primarily on CRISPR/Cas-mediated DNA-free genome editing and its applications in crop improvement. After targeted genome cleavage, the editing elements are rapidly degraded, leaving only the desired genomic modification and resulting in plants indistinguishable from those developed through conventional breeding. To achieve targeted, DNA-free genome editing, researchers have developed numerous molecular platforms and delivery systems, such as protoplast transfection, biolistic bombardment, nanoparticle-based systems, and emerging pollen- and meristem-targeted systems, for major crop species. Researchers have successfully enhanced several notable traits, including disease and pest resistance, nutritional quality, abiotic stress tolerance, and agronomic performance, in cereals, vegetables, oilseeds, and perennial crops. Recent advancements, including base editing, prime editing, and multiplex gene editing, are further expanding the precision, efficiency, and scope of DNA-free genome editing. Overall, CRISPR/Cas-mediated DNA-free genome editing offers a route to crop improvement that avoids stable transgene integration, though its wider deployment depends on progress in regeneration, molecular validation, and regulatory convergence.},

abstract = {A critical phase of mammalian brain development takes place after birth. Neurons of the mouse neocortex undergo dramatic changes in their morphology, physiology, and synaptic connections during the first postnatal month, while properties of immature neurons, such as the capacity for robust axon outgrowth, are lost. The genetic and epigenetic programs controlling prenatal development are well studied, but our understanding of the transcriptional mechanisms that regulate postnatal neuronal maturation is comparatively lacking. By integrating chromatin accessibility and gene expression data from two subtypes of neocortical pyramidal neurons in the neonatal and maturing brain, we predicted a role for the Krüppel-like factor (KLF) family of transcription factors in the developmental regulation of neonatally expressed genes. Using a multiplexed CRISPR interference (CRISPRi) knockdown strategy, we found that a shift in expression from KLF activators (Klf6, Klf7) to repressors (Klf9, Klf13) during early postnatal development functions as a transcriptional 'switch' to first activate, then repress a set of shared targets with cytoskeletal functions including Tubb2b and Dpysl3. We demonstrate that this switch is buffered by redundancy between KLF paralogs, which our multiplexed CRISPRi strategy is equipped to overcome and study. Our results indicate that competition between activators and repressors within the KLF family regulates a conserved component of the postnatal maturation program that may underlie the loss of intrinsic axon growth in maturing neurons. This could facilitate the transition from axon growth to synaptic refinement required to stabilize mature circuits.},

To date, ex vivo CRISPR/Cas-based gene therapies represented by Casgevy have achieved significant clinical advances. Nevertheless, cumbersome operational workflows and prohibitive treatment costs severely hinder their widespread clinical accessibility. In contrast, in vivo CRISPR/Cas-based gene therapies stand out with convenient administration procedures and reduced overall costs, endowing them with enormous translational potential. Although it holds great promise, the clinical translation of in vivo CRISPR/Cas-based gene therapies remains hampered by a number of factors. Among those multiple obstacles restricting the clinical translation of in vivo CRISPR/Cas-based gene therapies, delivery systems constitute the core bottleneck dominating in vivo editing efficiency and therapeutic potency. Centered on delivery platforms for in vivo CRISPR/Cas-based gene therapies, this review systematically summarizes prevailing in vivo CRISPR/Cas nano delivery systems, recapitulates relevant preclinical and clinical outcomes, discusses translational hurdles, and prospects the evolution of next-generation delivery systems, aiming to facilitate further development of in vivo CRISPR/Cas-based gene therapies.},

abstract = {Bacteria-phage interactions are often studied in relatively simple experimental systems involving a single bacterial strain infected by a single phage.[1] In natural environments, however, bacteria typically inhabit complex multispecies communities where species compete for limited resources and ecological niches.[2][,][3][,][4] Recent studies show that the microbial community context can have profound effects on the evolution of phage resistance.[5] For example, Pseudomonas aeruginosa evolves phage resistance primarily through receptor loss when grown in isolation but switches to CRISPR-based immunity in the presence of bacterial competitors.[6][,][7] Previous work showed that interspecies competition can favor CRISPR-immune bacteria over surface mutants after phage resistance has evolved.[6] However, it remains unknown whether competition also alters the initial generation of CRISPR immunity by changing CRISPR-Cas expression and spacer acquisition before selection among resistance phenotypes occurs. Here, we show that interbacterial competition can trigger CRISPR-Cas activation and adaptation in P. aeruginosa. When co-cultured with Acinetobacter baumannii, P. aeruginosa exhibited markedly increased expression of CRISPR-Cas genes and a higher frequency of new spacer acquisition, whereas no such induction occurred in monoculture or mixed communities lacking A. baumannii. This upregulation was associated with markers of DNA damage and stress signaling, indicating that competition-induced stress primes the bacterial adaptive immune response. These findings identify interbacterial antagonism as an ecological and physiological trigger for CRISPR activation, linking competitive interactions to enhanced antiphage defense. More broadly, our results suggest that bacteria sense and respond to competitive stress in complex microbial communities by increasing the generation of more adapted genotypes.},

This review critically summarizes the principles and recent applications of CRISPR/Cas12, Cas13, and emerging Cas14-based diagnostic approaches in veterinary parasitology, covering protozoan, helminthic, and arthropod-borne parasites. It further compares CRISPR platforms and discusses their integration with isothermal amplification, lateral flow assays, fluorescence detection, and portable biosensors to improve diagnostic performance. Moreover, current challenges, including sample preparation, assay standardization, multiplex detection, regulatory approval, and commercialization, are highlighted. Finally, future perspectives on amplification-free CRISPR assays, artificial intelligence-assisted diagnostics, and point-of-care platforms are discussed.

This article provides a detailed overview of the development of B. cereus detection techniques in food, transitioning from traditional methods to a series of current technologies such as immunology, molecular biology and MALDI-TOF-MS. The principles, advantages and disadvantages of various detection techniques, as well as their application progress, were outlined. Furthermore, the application and advantages of combining different techniques in the detection of B. cereus in food were demonstrated. The CRISPR/Cas system possesses the characteristics of high specificity, high sensitivity and ease of operation, and shows great potential in the field of foodborne pathogen detection. This article also explains that the combination of CRISPR/Cas technology with RPA, LFA and AI technologies can further enhance the detection rate and accuracy. The aforementioned technology can enable the early detection and prevention of B. cereus in food, ensuring food safety and preventing the outbreak of foodborne diseases. This article has certain reference value in the research on the detection techniques of B. cereus and other foodborne pathogens in food, and provides strong support for safeguarding food safety and maintaining human health.},

They can influence horizontal gene transfer, phage resistance, and antimicrobial resistance (AMR) dynamics. Although these systems have been investigated in several Klebsiella species, information on historically defined Raoultella species remains limited. In this study, 103 complete genomes representing Raoultella species, currently placed within the broader Klebsiella lineage, were analyzed to characterize the distribution, architecture, and diversity of CRISPR-Cas systems. CRISPR-Cas loci were identified using CRISPRCasFinder and CRISPRone, followed by subtype classification, direct repeat and leader sequence analyses, spacer matching, Cas1-based phylogenetic analysis, and AMR determinant screening. Complete CRISPR-Cas systems were detected in 23 genomes, predominantly in R. ornithinolytica strains. All complete systems were chromosomally located, whereas plasmid-associated orphan CRISPR arrays were observed in selected R. ornithinolytica strains. Two major architectures were identified, with Type I-E being dominant and Type I-F restricted to fewer strains. Direct repeat analysis revealed six consensus sequences, while leader regions displayed conserved AT-rich motifs and strain-specific divergence. Spacer analyses suggested historical interactions with phages and plasmids, particularly mobile genetic elements associated with Klebsiella and other Enterobacteriaceae. Cas1 phylogeny showed subtype-dependent clustering, indicating that CRISPR-Cas evolution does not strictly follow core genome phylogeny. The coexistence of predicted CRISPR-Cas loci and AMR determinants indicates that the presence of these loci does not necessarily preclude the carriage of resistance determinants. Overall, this study expands current knowledge of CRISPR-Cas diversity among the analyzed Raoultella genomes and provides a genomic framework for future functional studies.},

abstract = {Collagens are synthesized in the endoplasmic reticulum (ER), where their biosynthesis, quality control, and secretion are tightly coordinated to maintain collagen proteostasis. TANGO1L is an ER exit site protein required for efficient collagen secretion; however, whether it contributes equally to the secretion and intracellular homeostasis of different collagen types remains unclear. Here, we systematically examined the consequences of TANGO1L deficiency using CRISPR/Cas9-generated TANGO1L knockout human fibroblasts. Loss of TANGO1L reduced the secretion of multiple major collagen types and delayed secretion of newly synthesized collagen I. Intracellular responses, however, differed markedly among collagen types: collagen V accumulated intracellularly, whereas collagens I, III, and IV avoided intracellular retention despite markedly reduced extracellular secretion. This differential response was accompanied by decreased collagen gene expression and selective remodeling of the ER collagen biosynthetic machinery, suggesting that these cells adjust collagen synthesis to a reduced secretory capacity. TANGO1S protein was consistently upregulated through a post-transcriptional mechanism, suggesting an adaptive response to chronic TANGO1L deficiency. Biochemical analysis of collagen purified from the culture medium revealed a trend toward modestly increased lysine post-translational modifications, including hydroxylysine glycosylation, without altered triple-helical structure or thermal stability, indicating that TANGO1L deficiency compromises the quantity rather than the quality of secreted collagen. Together, these findings establish that the requirement for TANGO1L differs among collagen types and that its loss induces adaptive remodeling of intracellular collagen proteostasis rather than simply impairing collagen secretion, providing a framework for understanding how secretory cells maintain collagen homeostasis when secretion is compromised.},

abstract = {Cucumber (Cucumis sativus L.) is an economically important vegetable crop cultivated worldwide, but its sustainable production is increasingly threatened by Cucumber green mottle mosaic virus (CGMMV). CGMMV is a positive-sense single-stranded RNA virus belonging to the genus Tobamovirus and represents a major constraint on cucurbit production because of its efficient seed transmission, mechanical spread, environmental persistence, and broad host range. Infection can cause leaf mosaic and mottling, growth suppression, and severe fruit symptoms, including internal discoloration, water-soaked tissues, and flesh deterioration, resulting in substantial losses in yield and commercial quality. Recent advances in cucumber genomics, resistance-germplasm screening, host-virus interaction studies, and molecular breeding have provided new opportunities for improving CGMMV resistance. However, progress remains constrained by the scarcity of well-characterized resistance donors, the limited functional validation of cucumber-specific resistance genes, isolate-dependent resistance responses, and the relatively low efficiency of cucumber transformation and genome editing. This review summarizes current knowledge of CGMMV infection processes, host susceptibility factors, antiviral defense pathways, resistance resources, and resistance-associated loci in cucumber and related cucurbits. Evidence is interpreted according to host species and the level of experimental validation. It further evaluates the potential of marker-assisted selection, genomic selection, genome editing, and RNA-based engineering and outlines an integrated framework for translating molecular findings into durable CGMMV-resistant cucumber cultivars.},

abstract = {Gene editing therapy represents a promising strategy to permanently cure cystic fibrosis (CF). This paper presents the results of correcting the most common CF mutation, F508del, in the CFTR gene in airway basal cells (BCs) obtained from patients, using both classical CRISPR-Cas9-mediated homology-directed repair (HDR) and prime editing techniques. Our findings demonstrate that both methods achieve mutation correction with efficiencies reaching up to 18.9% of alleles in successfully transfected cells. However, the CRISPR-Cas9 approach results in insertions and deletions (indels) in approximately 15% of alleles at the editing site, whereas prime editing induced only minimal indel events. Functional analysis evaluating the effectiveness of gene editing revealed that prime editing of the F508del mutation in the CFTR gene-using the pegRNA4 combined with the PE2-NG variant-restores CFTR channel conductance, comparable to triple therapy with CFTR modulators (ivacaftor/tezacaftor/elexacaftor). While both prime editing and CRISPR-HDR resulted in successful correction of the CFTR-F508del mutation in patient BCs, prime editing exhibited a low frequency of unintended modifications both within and outside the editing locus, making this approach a promising candidate for the development of gene therapy strategies for CF.},

abstract = {Huanglongbing (aka: citrus greening) associated with 'Candidatus Liberibacter asiaticus' (CLas) is one of the most impactful citrus diseases throughout the world. The aim of this project was to support the sensitive and rapid detection of CLas to prevent the continued spread and destruction of US citrus crops by this psyllid vector-borne disease. Two multicopy targets specific to CLas were selected for assay development: the five-copy nrdB (ribonucleotide reductase-RNR) gene and a four-copy locus 4cp (4CP). Published RNR RPA primers were used to develop a one-pot RPA-CRISPR assay, and RPA primers for 4CP were designed. crRNAs for both RNR- and 4CP-RPA-CRISPR/Cas assays were designed, evaluated through preliminary testing, and the best candidate primers and crRNA combinations were selected. The 4CP assay was selected and subjected to a battery of validation tests and determined fit-for-purpose. A field extraction protocol was also developed using commercial reagents, syringes and filters to bring kit sensitivity to the field. When combined with the assay, the complete workflow was able to detect CLas in infected citrus, down to a single infected leaf per subsample; the field workflow showed similar sensitivity to the laboratory-based workflow. While the extraction and assay proved useful, particularly for symptomatic leaves, its performance with asymptomatic leaves for early detection was not evaluated. The complexity of the assay in its current form hinders widespread practical applicability. In the future, revalidation of lyophilized reagents in a convenient kit can be performed for practical deployment; preliminary testing has shown success.},

abstract = {Tomato improvement often involves trade-offs between fruit yield and quality, sweetness and fruit size, disease resistance and growth, reproductive performance and stress adaptation, and shelf life and flavour. Although CRISPR-Cas-mediated genome editing enables targeted modification of tomato genes, DNA-level precision does not guarantee an agronomically favourable phenotype because pleiotropy, functional redundancy, allele dosage, linkage, epistasis, genetic background, and environmental conditions can alter editing outcomes. This review evaluates genome editing as a strategy to manage, rather than merely document, these trade-offs. We examine how knockout, multiplex, cis-regulatory, base, prime, and direct allele-repair approaches can match the causal architecture of a breeding constraint. We critically assess representative studies involving plant architecture, reproductive development, fruit size, sugar accumulation, ripening, nutritional composition, disease resistance, and heat resilience, with an emphasis on heritability, molecular identity, multi-trait effects, and agronomic penalties. We further consider domestication-associated variation, structural variation, transformation and regeneration limitations, genotype-by-environment interactions, breeding deployment, and regulatory translation. We propose a trade-off-aware framework that links causal-allele identification, mechanism-matched editing, quantitative allele design, multidimensional phenotyping, and validation across generations, genetic backgrounds, and production-relevant environments. This framework can guide the development of balanced, breeding-ready tomato cultivars rather than lines optimized for a single trait.},

abstract = {Genome editing is becoming an important tool for crop improvement by enabling precise modification of genetic variation. CRISPR-Cas technologies have expanded beyond nuclease-induced mutations to include base and prime editing, transcriptional and epigenetic regulation, multiplex editing, organelle editing and targeted DNA insertion. These advances support the development of agronomically valuable alleles and extend crop improvement beyond conventional selection, recombination and random mutagenesis. Applications now include plant architecture, yield-related traits, resistance to biotic and abiotic stresses, seed composition and nutritional quality, and extend to de novo domestication, haploid induction and hybrid breeding. Current research is increasingly moving from single-gene modification toward the engineering of promoters, cis-regulatory elements, quantitative alleles and multiple-gene editing, particularly in polyploid crops. Wider breeding applications will depend on efficient delivery and regeneration, recovery of transgene-free and heritable edited germplasm, reliable targeted insertion and validation across relevant environments. Integration with pangenomics, multi-omics, phenomics, artificial intelligence and predictive breeding may further improve target identification, allele design and prediction of editing outcomes, thereby supporting the development of more precise and efficient crop-breeding strategies.},

abstract = {Porcine reproductive and respiratory syndrome virus (PRRSV) remains a major economic burden on the global swine industry. Identifying host factors that mediate viral invasion is critical for developing antiviral strategies. Here, using a CRISPR screen targeting genes encoding cell surface CD proteins combined with yeast two-hybrid screening, we identified the tetraspanin CD81 as a novel host factor that promoted PRRSV infection by directly interacting with viral glycoprotein 5 (GP5). CD81 knockdown reduced PRRSV infection, whereas CD81 overexpression enhanced it. Consistently, antibody-mediated blockade of CD81 restricted infection in both Marc-145 cells and primary porcine alveolar macrophages. Mechanistic analysis showed that CD81 mainly facilitated viral internalization, and its C-terminal transmembrane region was required for GP5 binding and efficient infection. During infection, CD81 underwent autophagic degradation mediated by the selective autophagy receptor NDP52, suggesting a host restriction response that reduced CD81 availability. PRRSV countered this process by promoting NDP52 degradation, thereby stabilizing CD81 and favoring infection. These findings identify CD81 as both a key factor in PRRSV pathogenesis and a potential target for antiviral intervention.IMPORTANCEPorcine reproductive and respiratory syndrome virus (PRRSV) remains one of the most economically important swine pathogens worldwide, yet effective antiviral strategies are lacking because of its extensive genetic diversity and immune evasion. Here, we identified the tetraspanin CD81 as a previously unrecognized host factor that promoted efficient PRRSV infection. CD81 directly interacted with the viral glycoprotein GP5 to facilitate viral internalization, whereas disruption of CD81 by genetic depletion or antibody blockade markedly restricted infection. We further demonstrated that CD81 abundance was controlled by NDP52-mediated selective autophagy as an intrinsic antiviral mechanism, which PRRSV overcame by degrading NDP52 to stabilize CD81 and enhance viral replication. These findings reveal a previously unrecognized virus-host interaction that governs PRRSV entry and identify CD81 as a promising host-directed therapeutic target.},

An important advantage of this method is the possibility to maintain the unedited HLA‑E gene. The antigen-presenting function of the resulting cells was successfully restored by transduction of a single HLA class I allele. Cells expressing monoallelic HLA‑A, after processing SARS-CoV‑2 epitopes, induced the allele-specific immune response in leukocytes isolated from patients who had recovered from COVID-19.

abstract = {OBJECTIVES: Zinc is widely present in the oral microenvironment and can influence the growth of oral bacteria. ZccR is a MerR-type transcriptional regulator that controls zinc efflux in Streptococcus mutans (S. mutans), but its role in biofilm virulence and interspecies competition with oral commensals remains unclear. This study aimed to investigate the role of ZccR in the formation of single-species biofilms of S. mutans and dual-species biofilms with oral commensal streptococci, and its underlying regulatory mechanisms.

METHODS: We constructed an in-frame zccR knockout mutant of S. mutans. The growth curve, crystal violet staining, anthrone method, scanning electron microscopy, fluorescence in situ hybridization, and deferred antagonism assay were used to assess growth, biofilm development, dual-species biofilm composition, and interspecies competitive capacity. RNA-seq was employed to identify genome-wide transcriptional alterations, and promoter-lacZ reporter strains were constructed to confirm the transcriptional regulation mode of ZccR on zccE and on itself.

RESULTS: The deletion of zccR significantly suppressed biofilm formation and water-insoluble exopolysaccharide production of S. mutans at 150 μM Zn[2+], a concentration that only modestly affected planktonic growth. In dual-species biofilms containing Streptococcus gordonii (S. gordonii), the mutant exhibited reduced oxidative stress tolerance and weaker inhibition of S. gordonii, despite upregulation of bacteriocin genes. RNA-sequencing identified 89 differentially expressed genes (67 upregulated and 22 downregulated), including downregulation of the mutanobactin cluster and FAD-dependent oxidoreductases, upregulation of iron-uptake genes, induction of HomR-tcy-linked cystine-uptake pathways, glutamine biosynthesis, and CRISPR-Cas genes, and a shift from sucrose import (scrA/msmX) toward lac-dependent lactose/galactose metabolism. Most of these shifts tracked intracellular zinc accumulation rather than direct ZccR control. Promoter-lacZ assays revealed that ZccR activates zccE and represses its own promoter, and zinc acts on these promoters through ZccR-dependent and ZccR-independent routes.

CONCLUSIONS: ZccR links zinc homeostasis with biofilm formation and oral interspecies ecology of S. mutans, thus offering a future intervention point for cariogenic biofilm control.},

Among the reported variants, USP26 cluster variants (c.370_371insACA/c.494 T > C/c.1423C > T) represent a frequently reported variant pattern in certain populations. Rapid and convenient detection of USP26 cluster variants may serve as a powerful tool for male infertility-associated cohorts. Here, we develop a CRISPR/Cas12a-based assay to rapid detection USP26 variants in human samples. Candidate CRISPR RNAs (crRNAs) and RPA primers were screened and optimized, followed by incorporation of restriction enzymes to reduce wild-type-derived amplification interference. Using controlled artificial DNA mixtures, the assay detected mutant-template fractions down to 5% under the tested conditions. The complete workflow could be performed within 60 min using basic laboratory equipment. The results of the CRISPR/Cas12a system are consistent with Sanger sequencing in 91 male infertility research samples. Overall, our study establishes a rapid molecular detection method for detecting USP26 cluster variants and provides an alternative approach for genetic studies of male infertility-associated cohorts.},

However, most BGCs are transcriptionally silent under standard testing conditions and may require a complex, integrated approach for activation. In this review, we revisit previous approaches to activating BGCs, focusing on polyketides. We additionally discuss how integrating genome mining strategies with multi-omics integration, synthetic biology methods, and precise genome-editing tools is providing increasingly precise strategies for the discovery and engineering of polyketide-producing Streptomyces. We further discuss how to couple artificial intelligence (AI)-designed promoters could enable the production of novel compounds with improved yields, expanded chemical diversity, and enhanced industrial potential. We further examine how state-of-the-art CRISPR-Cas systems, including base editing, facilitate precise editing of high-GC-content genomes while circumventing the genome instability and Cas9-associated cellular toxicity that frequently accompany double-strand break formation in Streptomyces, and how chromatin topology rewiring dismantles transcriptional silencing. Unlike reviews that address genome mining, pathway engineering, or genome editing as separate approaches, this review presents an integrated framework linking computational BGC prediction, multi-omics validation, and precision engineering to prioritize and activate cryptic polyketide pathways in Streptomyces. We propose comprehensive computational genomics prediction approaches and integrate them with experimental validation through promoter engineering, transcription factor decoys, and chassis strain optimization, highlighting how these methods and tools are advancing the field from descriptive BGC catalogs to scalable, predictive models for next-generation drug discovery. Future efforts to couple AI-generated, sequence-orthogonal promoter libraries with biology-based modeling hold great promise.},

In this issue of the JCI, Sivakumar et al. harnessed CRISPR/Cas9 editing of endogenous hematopoietic stem and progenitor cells (HSPCs) to excise the frataxin gene (FXN) repeat expansion ex vivo, followed by autologous transplantation. A single, systemic infusion of corrected HSPCs resulted in long-term engraftment and sustained multiorgan benefit in a humanized mouse model of FRDA. This improvement in brain, cardiac, and pancreatic symptoms, mediated by myeloid progeny of the engrafted stem cells, provides strong support for the potential effectiveness of this approach in humans and bypasses the need to correct the FXN deficiency in the affected tissue and cells directly.},

RECENT FINDINGS: There are two ongoing clinical trials in humans to edit PCSK9 using CRISPR-Cas9 base editing technology packaged within lipid nanoparticles (LNPs). Preliminary interim and preclinical data suggest that this strategy is effective for long-term reduction of PCSK9 and LDL-C following a single IV infusion. Monoclonal antibodies that neutralize circulating PCSK9 have demonstrated the utility of PCSK9 inhibition for reducing LDL-C and ASCVD. Although there is an increasing number of pharmacologic strategies for inhibiting PCSK9, gene editing is an attractive option due to its potential to permanently reduce circulating PCSK9 levels and by extension LDL-C and ASCVD. There are two ongoing clinical trials in humans investigating the safety and efficacy of gene editing for PCSK9 with encouraging preliminary results. In this review, we will describe the background of PCSK9 as a target, the gene editing machinery and the preliminary results. We also explore the unique safety challenges of this technology and propose considerations for appropriate patient populations to maintain net positive benefits despite unknowns.},

abstract = {CRISPR-based technologies have transformed experimental biology by enabling precise, efficient, and programmable manipulation of the genome and epigenome. This chapter provides a comprehensive and practical guide to genetic and epigenetic editing using CRISPR technology, with a particular focus on applications in Ewing sarcoma cell models. We describe strategies for CRISPR-mediated gene knockout (CRISPR KO) via nonhomologous end joining (NHEJ), precise gene knock-in (CRISPR KI) through homology-directed repair (HDR), and reversible transcriptional modulation using CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa). We emphasize the use of ribonucleoprotein (RNP) delivery of Cas9 and single guide RNAs, which offers improved editing efficiency, reduced off-target activity, and enhanced safety compared to plasmid-based approaches. Detailed protocols are provided for guide RNA design, RNP assembly, electroporation-based delivery, single-cell cloning, and molecular validation of edited clones. In addition, we outline best practices for HDR template design, discuss strategies to improve KI efficiency, and address common challenges such as polyploidy, variable editing rates, and DNA-mediated cytotoxicity. For CRISPRi and CRISPRa applications, we describe plasmid-based systems employing catalytically inactive Cas9 fused to transcriptional repressors or activators, enabling potentially tunable and reversible control of endogenous gene expression. Throughout the chapter, practical advice, troubleshooting tips, and critical considerations are included to facilitate successful implementation across diverse experimental settings. Collectively, this chapter serves as a detailed methodological resource for researchers aiming to employ CRISPR-based engineering for functional studies.},

abstract = {Since the discovery of the clustered regularly interspaced short palindromic repeat (CRISPR)-associated (Cas) system, genome-editing technologies have advanced rapidly, and the field has expanded substantially. In parallel, artificial intelligence (AI) has progressed at an unprecedented pace and is transforming genetic engineering. Early AI applications primarily addressed predictive tasks, including guide RNA (gRNA) activity, off-target effects, and editing outcomes for CRISPR-Cas nucleases, base editors, and prime editors. Recently, transformer-based protein language models (PLMs) and generative AI have expanded the role of AI beyond prediction to direct molecular design. Thus, AI-driven frameworks can now evolve genome-editing proteins, design molecular architectures, and generate de novo genome-editing enzymes. This review discusses how AI is reshaping genome engineering, from gRNA activity prediction to the design of next-generation editors.},

abstract = {Exosomes are an evolved sub-type of extracellular vesicles (EVs) that have gained popularity in recent years as a novel biological nanocarrier system for targeted precision therapy in cancer owing to their excellent biocompatibility, low immunogenicity, and high stability. While other artificial systems can only deliver specific types of drug, exosomes have been found to effectively carry different types of therapeutic cargo, such as chemotherapeutic agents, proteins, peptides, mRNA, siRNA, miRNA, and even CRISPR/Cas gene editing elements. Recent progress in exosome engineering technologies, such as surface modification, donor cell modification, bionic hybrid vesicles, and stimuli-responsive exosomes, has improved their targeting efficacy, cargo-loading capacity, and controlled drug release properties. Apart from their therapeutic use, exosomes play an active role in promoting tumor development by regulating the tumor microenvironment, angiogenesis, metastasis, immune escape, maintenance of cancer stem cells, and drug resistance. This review provides a brief insight into the biological properties of exosomes, recent developments in isolation and characterization methods, engineering approaches, therapeutic cargo loading, and their uses in targeted chemotherapy, gene and RNA therapy, immunotherapy, phototherapy, sonodynamic therapy, chemo-dynamic therapy, and combinational therapy. Moreover, the existing issues in exosome research, such as exosome heterogeneity, large-scale production, quality control, and regulatory issues, are addressed. Finally, new approaches involving artificial intelligence, multi-omics technology, and personalized engineering of exosomes are presented as potential solutions to enhance the clinical use of exosomes.},

abstract = {Prolidase (PEPD) is a metalloproteinase that hydrolyzes imidodipeptides containing proline or hydroxyproline at the C-terminus and also participates in the non-catalytic regulation of cellular stress responses and p53 availability. Here, we characterized population-level responses associated with transient CRISPR/Cas9-directed targeting of PEPD in heterogeneous MCF7 breast cancer cultures using three independent sgRNAs. PEPD enzymatic activity was quantified in three independent biological experiments, whereas PEPD and p53/apoptosis-related proteins were examined by representative Western blotting and exploratory immunofluorescence microscopy. All three PEPD-targeting constructs were associated with reduced population-average PEPD activity, and representative immunoblots showed directionally concordant reductions in PEPD protein signal. Representative protein analyses additionally revealed a qualitative pattern involving p53, MDM2, cleaved caspase-9, cleaved caspase-7, and cleaved PARP-1. These protein observations were not supported by independent biological replication suitable for inferential analysis and are therefore interpreted descriptively. Editing of the endogenous PEPD locus was not directly confirmed or quantified by genomic analysis. During prolonged puromycin selection, the persistence of adherent PEPD-targeted cells decreased under the conditions tested; however, this experiment was qualitative and was not designed as a formal viability or rescue assay. Collectively, the data demonstrate a replicated population-level reduction in PEPD enzymatic activity following PEPD-directed CRISPR/Cas9 perturbation and identify an associated exploratory p53/MDM2- and apoptosis-related protein pattern. A contribution of Cas9-mediated DNA-damage signaling to the latter cannot be excluded.},

abstract = {Toxic metal contamination of soil remains a critical global challenge due to the persistence, bioaccumulation, and irreversible toxicity of these metals. Cadmium (Cd), lead (Pb), mercury (Hg), arsenic (As), chromium (Cr) and nickel (Ni) are the most common toxic metals that threaten food security, ecosystem stability, and human health. While conventional physicochemical remediation technologies provide rapid pollutant removal, they are constrained by high economic costs, secondary pollution risks, and long-term soil degradation. Biological approaches, particularly phytoremediation and microbial mitigation, offer environmentally compatible alternatives; however, their field-scale performance is often limited by low biomass production, restricted metal bioavailability, microbial instability, and heterogeneous soil conditions. This review critically synthesizes recent advances that move beyond standalone biological strategies toward integrated, multi-scale remediation frameworks. We evaluate the mechanistic basis and performance of nano-assisted phytoremediation, biochar-mediated stabilization, omics-guided plant-microbe optimization, and clustered regularly interspaced short palindromic repeats/CRISPR-associated protein systems (CRISPR/Cas) for enhancing metal transport, chelator biosynthesis, antioxidant defense, and microbial detoxification pathways. Emerging evidence indicates that nano-enabled amendments and biochar composites can reduce bioavailable Cd fractions by up to 75%, while omics-driven microbial consortia and targeted genome editing improve tolerance and accumulation efficiency in key crops such as rice and sorghum. Importantly, we assess translational barriers including nanoparticle ecotoxicity, off-target genome effects, regulatory constraints, biomass disposal, and life-cycle sustainability that currently limit large-scale deployment. By integrating mechanistic insights with field validation data, risk assessment considerations, and technology readiness evaluation, this review proposes a conceptual roadmap for scalable, eco-efficient soil restoration. The convergence of nanotechnology, systems biology, microbiome engineering, and precision genome editing represents a transformative pathway for next-generation remediation strategies capable of restoring contaminated soil while safeguarding environmental and public health.},

abstract = {BACKGROUND: Gonorrhea, caused by the human obligate pathogen Neisseria gonorrhoeae, is the second most common bacterial sexually transmitted infection worldwide. In the absence of an effective gonococcal vaccine, convenient and accurate diagnosis of N. gonorrhoeae infection is essential for optimal patient management and for interrupting ongoing transmission.

METHODS: A custom-designed gold nanoparticle-based lateral flow biosensor (AuNP-LFB) was employed. The unique LAMP primers and a specific single-guide RNA (sgRNA) were designed to target the orf1 gene of N. gonorrhoeae. The key diagnostic conditions, including detection temperature and time, were optimized. The sensitivity and specificity of the assay were validated, and its clinical feasibility was validated using seventy-eight genital secretion samples from patients suspected of N. gonorrhoeae infection.

RESULTS: The custom-designed AuNP-LFB was successfully fabricated. The Ng-CRISPR-One-Pot assay achieved a limit of detection (LoD) as low as 7 copies per test and exhibits no cross-reactivity with other tested microbial species. The entire detection workflow, including nucleic acid extraction (10 min), LAMP-CRISPR/Cas12b detection (56 °C, 50 min), and AuNP-LFB visual readout (< 2 min), can be completed within 65 min without requiring specialized instrumentation. Compared with a reference N. gonorrhoeae-qPCR method, our assay achieved 100% sensitivity (95% CI: 93.94-100.00%) and 100% specificity (95% CI: 82.35-100.00%).

CONCLUSIONS: Collectively, these preliminary results indicate that the Ng-CRISPR-One-Pot assay holds promise as a practical point-of-care (POC) diagnostic tool, enabling accurate and convenient detection of N. gonorrhoeae, particularly in resource-limited settings.},

abstract = {Gene amplification plays a critical role in evolution and disease and is widely utilized to overexpress valuable gene products in biotechnology. To broaden these applications, we previously developed break-induced replication (BIR)-mediated tandem repeat expansion (BITREx), a method utilizing Cas9 nickase (nCas9) to amplify genetic sequences by driving tandem array expansion through ectopic BIR. Since BITREx efficiency depends on the guide RNA (gRNA) recruiting nCas9 to the array's flanking regions, here we develop a plasmid-based reporter system in budding yeast for the rapid identification of high-performing gRNAs. Furthermore, we introduce BITREx 2.0, a dual-nicking strategy that targets both sides of the gene array. We demonstrate that BITREx 2.0 is effective for both natural and synthetic arrays, enhancing expansion efficiency by up to an order of magnitude compared to the original single-nicking format. These advancements significantly broaden the applicability and efficiency of nCas9-mediated gene amplification across diverse biological and biotechnological contexts.},

abstract = {Most cases of autosomal dominant polycystic kidney disease (ADPKD) are caused by mutations in PKD1, which reduce polycystin-1 (PC1) levels below a critical functional threshold. Normalizing PC1 dosage mitigates disease progression; therefore, we sought to develop a CRISPR activation (CRISPRa) strategy to transcriptionally upregulate endogenous PKD1. We systematically screened multiple single-guide RNAs using an EGFP-reporter platform and identified potent candidates targeting the proximal PKD1 promoter in mouse and human cell models. Our results demonstrate that CRISPRa effectively increased endogenous Pkd1 mRNA in the mouse collecting duct-derived Pkd1[RC/-] cell model and in the primary renal epithelial cells from PKD mice. In Pkd1[RC/-] cells, CRISPRa of Pkd1 increased PC1 protein levels and significantly reduced cell proliferation and in vitro cyst formation in 3-D cultures. Mechanistically, Pkd1 activation improved mitochondrial membrane potential, reduced dependency on aerobic glycolysis, and corrected signaling pathways involved in cystogenesis, specifically reducing intracellular cAMP, cMyc, pCreb, and pErk levels, while increasing pYap1 levels. We confirmed the translational potential of this platform by successfully activating PKD1 in primary renal epithelial cells from human kidneys. We observed a heterogeneous response across both normal and ADPKD patient-derived donor lines, with significant upregulation achieved in two of the tested cell preparations. These findings provide a compelling proof-of-concept that CRISPRa-mediated gene augmentation can increase PC1 levels, establishing a foundation for promising gene therapies aimed at successfully suppressing the pathogenic features of ADPKD.NEW & NOTEWORTHY This study provides proof-of-concept for a CRISPR activation (CRISPRa)-based approach to ADPKD. CRISPRa targeting the PKD1 promoter increased polycystin-1 levels in mouse and human cells. Upregulation of a hypomorphic Pkd1 allele increased functional polycystin-1, corrected dysregulated signaling pathways, and suppressed cell proliferation and in vitro cyst formation. These results establish CRISPRa as a promising therapeutic approach to restore polycystin levels above a critical threshold and suppress cystogenesis in ADPKD.},

abstract = {BACKGROUND: The SLC25A38 is one of the genes of the heme biosynthesis pathway and disruptive alterations therein cause autosomal recessive congenital sideroblastic anemia (CSA). Primary patient-derived fibroblasts can be used as a valuable source for disease modeling, cell therapy studies, and the generation of induced pluripotent stem cells. In addition, they are easy to isolate and grow rapidly in vitro. Therefore, effective gene correction in these cells could be an important step towards personalized therapies.

METHODS: In this study, fibroblast cells were isolated from a CSA patient and stained, determined by flow cytometry, and detected by immunocytochemistry. Subsequently, transfection optimization was performed with Lipofectamine.

RESULTS: After 24 h of transfection with Cas9/sgRNA3 expression plasmid and single-stranded oligodeoxynucleotide (ssODN) donor, a transfection efficiency of 49.64% was achieved. The presence of the ssODN donor in the target gene region was examined by PCR-RFLP and PAGE, observing two fragments with approximate sizes of 116 and 161 bp. These results are consistent with insertion of the ssODN donor into the target gene region in fibroblast cells isolated from the patient.

CONCLUSIONS: The findings of this study indicate that the use of the CRISPR/Cas9 system with the designed oligo donor, under the tested conditions, has the potential to produce the expected changes at the target gene locus in patient fibroblast cells. Complementary studies using sequencing, along with examining different transfection conditions, could help more accurately confirm the findings of this study and further optimize this approach for future studies.},

abstract = {As the non-human primate models with the closest genetic relationship to humans, laboratory monkeys are indispensable in life sciences research, drug development, and biological product evaluation. However, infectious diseases either endemic in laboratory monkey colonies or acquired during breeding and husbandry-for example, B virus and Mycobacterium tuberculosis-threaten animal welfare and colony security, while also elevating zoonotic transmission risks and compromising the reliability of research data. The diversity, complexity, and clinically insidious nature of diseases in laboratory monkeys impose stringent demands on veterinary diagnostic capabilities. This review summarizes the current status and recent advances in mainstream veterinary diagnostic techniques applied to laboratory monkey disease surveillance. We analyze the specific applications, strengths, and limitations of molecular, immunological, imaging, and conventional microbiological methods for detecting major viral, bacterial, and parasitic pathogens of laboratory monkeys, covering quantitative PCR (qPCR), CRISPR-based assays, ELISA, IFA/IHC, and other established platforms. By comparing these techniques across sensitivity, specificity, cost-effectiveness, and operational feasibility, we delineate their suitability for distinct use cases: high-precision laboratory testing, large-scale colony screening, and point-of-care clinical diagnosis. Current veterinary diagnostic assays for laboratory monkeys achieve robust analytical performance. In several studies, qPCR delivers 100% sensitivity and 100% specificity for B virus detection, digital PCR (dPCR) attains a limit of detection as low as 45 copies/ml for monkeypox virus; and CRISPR/Cas-based assays have demonstrated 100% sensitivity and 100% specificity in clinical validation cohorts. Building on these advances, we further identify practical bottlenecks in diagnostic deployment and propose targeted countermeasures. Finally, we explore emerging trends and application prospects for point-of-care testing, multiplex pathogen detection, and artificial intelligence-assisted diagnosis, which collectively support the development of accurate, efficient, and intelligent disease diagnostics for laboratory monkeys. This work aims to provide a theoretical and practical reference for clinical practice and scientific research focused on laboratory monkey disease prevention and control.},

Within MADS, the MAD3-MAD4 module has been proposed to function as an ATPase-nuclease module related to the OLD nuclease family, but the molecular basis of its assembly and function remains unknown. Here, we combined cryo-electron microscopy, X-ray crystallography, biochemical assays, and mutagenesis to elucidate the architecture and assembly mechanism of the MAD3-MAD4 complex. We found that MAD3 and MAD4 assemble into a stable 2:2 heterotetramer. Structural and biochemical analyses revealed that MAD3 alone lacks detectable ATPase activity, whereas MAD4 is insoluble when expressed alone. Assembly of the MAD3-MAD4 complex induces a conformational rearrangement in which MAD3 adopts an ATPase-competent dimeric conformation, while MAD4 is stabilized through intersubunit interactions. This heterotetrameric assembly exhibits both ATPase and DNA cleavage activities. Overall, our findings reveal the molecular basis of MAD3-MAD4 heterotetramer assembly and provide the first structural and biochemical insights into the function of the MAD3-MAD4 module within the MADS defense system.},

As genome editing advances toward clinical applications, incorporating population diversity becomes essential for ensuring therapeutic efficacy across diverse populations.

RESULTS: We present CRISPR-HAWK, a framework integrating individual- and population-scale variants and haplotypes into gRNA design. Analyzing therapeutic targets across 79 648 genomes reveals that genetic variants substantially alter guide performance. For the clinically approved sickle cell disease therapeutic guide targeting BCL11A, we identify haplotypes that completely abolish predicted cutting activity. Across seven therapeutic loci, 82.5% of guides contain variants modifying on-target activity. Variants also create novel protospacer adjacent motif sites generating individual-specific guides invisible to reference-based design. These findings demonstrate that variant-aware selection is critical for equitable genome editing.

abstract = {Botrytis cinerea is a polyphagous fungal pathogen affecting a wide range of ornamental and agricultural crops. Previous studies on natural populations have revealed substantial intraspecific morphological, physiological, and genetic diversity. The field isolate B459 exhibits a distinctive mycelial phenotype, characterized by the lack of sporulation and sclerotia formation, and is unable to infect Vitis vinifera or Phaseolus vulgaris leaves, gerbera petals and tomato fruits. Genetic analysis traced these phenotypes to a mutation in the transcription factor gene Bcin04g03490, introducing a premature stop codon and resulting in a truncated protein. To further investigate the function of Bcin04g03490, CRISPR/Cas9-based strategies were employed to generate B459 transformants either carrying a functional B05.10 allele under the control of the constitutive olicC promoter from Aspergillus nidulans integrated at the niaD locus, or repaired at the endogenous locus through a marker-free approach involving targeted cleavage upstream of the repair template. In both cases, restoration of sporulation and pathogenicity was observed. Notably, complemented and repaired strains also recovered the toxin profile characteristic of the reference aggressive B05.10 isolate, including the production of botrydial (sesquiterpene) and botcinins (polyketides), indicating reactivation of key secondary metabolism pathways. These findings extend the functional scope of Bcin04g03490, demonstrating that it controls developmental processes, pathogenicity, and secondary metabolism pathways critical for virulence. Furthermore, this work provides a proof-of-concept for long-range homology-directed repair in B. cinerea at the Bcin04g03490 locus, offering valuable methodological insights for marker-free genome editing in filamentous fungi.},

However, accurate detection of diverse mutations occurring at the same locus remains technically challenging. The CRISPR/Cas system, with its unique programmable nucleic acid recognition capabilities, provides a promising solution. Here, we elucidated that CRISPR/LwaCas13a is tolerant to consecutive substitutions but highly sensitive to insertions or deletions (indels) at specific positions of the spacer sequence, enabling rational CRISPR RNA (crRNA) design for multiplex detection of same-site indels. Guided by these principles, we achieved effective detection of ultra-multiplex nucleophosmin 1 (NPM1) c.863_864 4-bp insertions with a single crRNA, while maintaining specificity against the wild-type transcripts. We further established a one-pot CRISPR system, CRISPR-Scan, by integrating recombinase polymerase amplification with LwaCas13a cleavage. CRISPR-Scan enabled detection of mutations in backgrounds as low as 0.01%. In clinical validation, it identified NPM1 mutations in 43 of 120 AML patients, consistent with next-generation sequencing (NGS). Continuous monitoring of four AML patients indicated early recurrence with higher sensitivity than first-generation sequencing (FGS) and full concordance with NGS. A microfluidic chip and portable device further facilitate accurate AML mutation detection. This platform offers an efficient and convenient approach for early AML diagnosis and measurable residual disease (MRD) monitoring.},

abstract = {The CRISPR/Cas system, known for its high precision and efficiency in genome editing, has garnered significant interest and demonstrated potential in diagnostics, owing to advantages such as sensitivity and cost-effectiveness. However, the application of the CRISPR/Cas system in diagnostics is constrained by two inherent challenges. On one hand, the sensitivity of the CRISPR/Cas system for the direct detection of low-abundance targets remains to be further improved for the demands of practical detection. On the other hand, the integration of nucleic acid amplification with the CRISPR/Cas system in one-pot assays presents difficulty of balance between target amplification and cleavage of Cas proteins. To overcome these constraints, researchers have encouragingly developed diverse strategies for precisely adjusting the cleavage activity of the CRISPR/Cas system. This review systematically summarizes advancements across six major strategies, including protein engineering, crRNA engineering, activator engineering, reporter engineering, the influence of metal ions and small molecules, and aggregation-mediated enhancement. These approaches either enhance cleavage efficiency for amplification-free, ultrasensitive detection, or temporarily suppress the cleavage activity to coordinate kinetics in integrated one-pot systems. Furthermore, future perspectives are discussed, which will contribute to the development of cleavage activity adjustment of the CRISPR/Cas system, providing insights for next-generation diagnostic technologies.},

Congenital hydrocephalus (CH), characterized by enlarged ventricles filled with cerebrospinal fluid (CSF), is a leading cause of pediatric brain surgery, but its molecular mechanisms remain unclear. We have identified what we believe to be novel, recurrent, damaging missense variants in the SH3-binding domain of the adaptor protein growth factor receptor-bound protein 2 (GRB2) in unrelated patients with CH. GRB2 is significantly coexpressed with 1 of its known upstream RTK partners, CSF1R, in the developing human brain, particularly in a microglial subtype associated with regulation of neural stem cells. IP validated GRB2-CSF1R binding in mouse microglial cells and a human monocyte cell line. Cx3cr1-Grb2fl/fl mice engineered with conditional deletion of Grb2 in microglia exhibit congenital absence of microglia and early postnatal severe communicating (nonobstructive) hydrocephalus, mimicking the condition of patients with the GRB2 mutation. The severe ventriculomegaly of Cx3cr1-Grb2fl/fl mice is associated with both depletion of cerebral cortical neurons and impairment of glia-lymphatic-mediated CSF flow. Together, these findings implicate a role of GRB2 in microglia that could be essential for brain development and CSF homeostasis.},

abstract = {Gene delivery and the various routes of administration used to deliver viral vectors constitute a rapidly evolving field, with recent success in restoring hearing in children with OTOF variants in ongoing clinical otoferlin trials. With the rise of gene therapy for major hereditary hearing disorders, both syndromic and nonsyndromic, there has been parallel progress in the development of new delivery methods. Advances in intratympanic injection of antibiotics and corticosteroids, along with nearly half a century of experience in cochlear implantation surgery, have enabled multiple local and systemic approaches to access the inner ear. Recent industry investment in gene therapy and delivery technologies has accelerated scientific progress, underscoring the need for continuous evaluation of the most suitable gene delivery strategies for different causes of hearing loss. Although most gene delivery in animal models has been performed via round window membrane injection, yielding promising results in cochlear hair cell transduction, potential drawbacks remain for clinical translation-particularly limited vector distribution, which may result in a basal-to-apical gradient. Venting procedures such as stapes footplate fenestration or canalostomy have been explored to mitigate these limitations, and recent intrathecal or even in utero injections have been investigated as alternative approaches. Hearing loss can be inherited in multiple ways, and patient treatment with gene delivery, or even the type of gene therapy itself, may vary with the recent success of CRISPR/Cas-based editing tools. Understanding the genetic etiology of inner ear disorders has facilitated the identification of therapeutic targets and innovative delivery approaches. This review summarizes the current understanding of delivery routes for gene therapy, highlighting their respective strengths and limitations as demonstrated in translational and clinical research to date. Furthermore, it examines advances in drug delivery and clinical applications in the context of emerging therapeutics, providing an integrated overview and perspective on the future direction of gene delivery strategies.},

The vast majority of these biosensors are currently limited to in vitro applications, highlighting the need for cellular platforms. Here, we provide a perspective on the potential of type III CRISPR-Cas systems as a platform for real-time RNA biosensing in living cells. We discuss the unique properties that distinguish type III from other CRISPR-Cas types, including their intrinsic cyclic oligoadenylate (cOA) signal amplification cascade, PAM-free RNA targeting and the extensive biochemical diversity of their downstream CARF and SAVED effector proteins. We outline the fundamental design principles of a genetically encoded type III cellular biosensor, comprising a programmable guide RNA, a multi-subunit sensing complex and a cOA-sensing effector protein capable of generating optical or electrochemical readout signals. A remaining challenge for type III cellular biosensors is the inherent cytotoxicity of canonical cOA-activated effectors. We propose several strategies to re-engineer these outputs towards non-cytotoxic reporter systems. While cellular biosensors present a natural route toward in vivo sensing, they face many challenges beyond the choice of the output signal and hardware strategy. We conclude that type III CRISPR-Cas is a promising platform for programmable real-time RNA sensing in living cells, utilizing its diverse modular effector outputs, representing a significant expansion of the CRISPR biosensor toolkit, while emphasizing appropriate deployment scenarios that enables full potential of these biosensors.},

abstract = {BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with remarkably poor prognosis. Splicing dysregulation is emerging as a hallmark and possible therapeutic target of PDAC.

METHODS: We performed high-throughput RNA sequencing analyses in PANC-1 cells treated with three drugs targeting the U2 small nuclear ribonucleoprotein (U2 snRNP): Pladienolide B, Thailanstatin A and Indisulam. The efficacy of splicing inhibitors, Talazoparib, Alisertib, AZD7762 and Barisertib, alone or in combination, was assessed in PDAC cells and patient-derived organoids (PDOs) by cell viability assays. RT-PCR, western blot and cell cycle assays were performed to evaluate the expression of DNA repair and mitotic genes and the execution of mitosis. PANC-1 cells were engineered to stably co-express GFP-tagged H2b histone and RFP-tagged β-tubulin by CRISPR/Cas-9 technology and used for time-lapse confocal microscopy and immunofluorescence analyses.

RESULTS: Genes encoding for the U2 snRNP, which recognizes the 3' splice site, are upregulated in advanced PDAC. U2 snRNP-targeting drugs impair the DNA damage response (DDR) pathway in homologous recombination-proficient PDAC cells and PDOs, thus enhancing their sensitivity to PARP inhibitors. Genes whose splicing was disrupted by all three drugs are characterized by higher expression, more exon-intron junctions, weak 5' splice sites and atypical GC content. These features are enriched in mitotic genes (e.g. AURKA, AURKB, CHEK1), whose expression is strongly deregulated by splicing perturbation. Accordingly, splicing inhibition causes severe mitotic defects, leading to the accumulation of cells with misaligned condensed chromosomes on monopolar or bipolar spindles. Notably, high expression of AURKA, AURKB and CHEK1 correlates with poor prognosis in PDAC patients, whereas combined treatments with inhibitors of these mitotic kinases strongly impair the viability of PDAC cells and PDOs.

CONCLUSIONS: These findings uncover gene features associated with sensitivity to splicing inhibitors in PDAC cells and suggest that the DDR and mitosis are biological processes highly sensitive to splicing perturbation.},

By screening root-derived bacterial isolates across genetically diverse Caenorhabditis elegans strains, we identified striking phenotypic heterogeneity, ranging from lifespan extension to accelerated aging. Combining classical genetic analysis, quantitative trait locus (QTL) mapping and CRISPR-Cas9 allelic recapitulation, we identify skn-1 (Nrf2) and gsy-1 (glycogen synthase) as key host determinants. We demonstrate that strains with mutations or specific natural variants in these loci exhibit a compromised redox buffering capacity, leading to systemic oxidative stress, loss of tissue integrity, and premature death upon microbial challenge. Conversely, robust hosts utilize the same microbial signals to promote longevity. Notably, lifespan defects in susceptible individuals were rescued by antioxidant supplementation. These findings establish redox homeostasis as a central axis in host-microbe-aging interactions and provide a mechanistic framework for precision microbiome interventions tailored to host genetic backgrounds.},

abstract = {Rare genetic liver diseases collectively affect millions of individuals worldwide and encompass a heterogeneous group of monogenic disorders including Wilson disease, alpha-1 antitrypsin deficiency, glycogen storage diseases, urea cycle disorders, progressive familial intrahepatic cholestasis, and acute hepatic porphyrias. While conventional management relies on dietary modification, pharmacotherapy, and ultimately liver transplantation, the advent of clustered regularly interspaced short palindromic repeats (CRISPR)-based gene editing has opened transformative therapeutic avenues. This review provides a comprehensive and critical appraisal of the current landscape of CRISPR-based therapies for genetic liver diseases, from preclinical proof-of-concept studies to landmark clinical trials. We examine the evolution from conventional Cas9 nuclease-mediated editing to precision tools including base editors and prime editors, which enable single-nucleotide corrections without inducing double-strand DNA breaks. The role of lipid nanoparticle delivery systems in achieving efficient hepatocyte-targeted delivery is discussed, alongside emerging challenges in pediatric dosing and immunogenicity. We highlight the paradigm shift toward personalized, patient-specific CRISPR therapies, exemplified by the first-in-human bespoke gene editing treatment delivered in 2025. Competing nucleic acid technologies, including RNA interference and antisense oligonucleotides, are compared in terms of durability, safety, and cost-effectiveness. Finally, we critically evaluate the evolving regulatory landscape and propose a priority framework for selecting genetic liver diseases most amenable to CRISPR-based correction. This review underscores that CRISPR gene editing is transitioning from experimental promise to clinical reality for genetic liver diseases, with personalized approaches poised to redefine the treatment paradigm.},

In this study, we functionally modelled two novel SAMD9L variants-p.N697Y and p.K1294*-alongside two previously reported variants (p.T233N and p.H880Q). We generated heterozygous knock-in cellular models in the Human leukemia (HL-60 myeloid cell line) for each variant using homology-directed repair-based Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR/Cas9) gene editing. Functional assays, focused on proliferation and protein translation, confirmed that the p.T233N, p.N697Y and p.K1294* variants all caused a decreased rate of protein translation.

Here, we present a temporally and conditionally controlled m[5]C writing platform engineered through integrating abscisic acid (ABA)-mediated chemically induced proximity with split-dCas13b-NSUN2/NSUN6 technology. This system enables the writing of m[5]C by reconstituting the split dCas13b-based m[5]C editing complex at the guide RNA (gRNA)-targeted RNA transcript sites under the control of the inducer ABA. The deposition of m[5]C is inducible, reversible and selective. The deposited m[5]C is biologically active and influences the stability of endogenous mRNA transcripts. Moreover, by incorporating ABA prodrugs, the m[5]C writing can be triggered by signals associated with distinct physiological or disease conditions (e.g., tumor microenvironment and senescence). This conditional m[5]C editing strategy provides a new programmable tool for studying m[5]C biology in a context-dependent manner and expands the repertoire of RNA modification editing technologies.},

Effective outbreak management is hindered by the lack of rapid diagnostic methodologies deployable in field settings. Current testing approaches are limited by slow turnaround times for microbial culture and the dependence of qPCR on centralized laboratory infrastructure, both of which are poorly suited for field settings. To address this gap, we developed a highly sensitive, isothermal diagnostic platform coupling Recombinase Polymerase Amplification with CRISPR-Cas12a detection targeting the conserved uvrC gene. The optimized assay requires less than 1 h at 37°-39°C and achieves an analytical limit of detection of approximately 8 copies, comparable to that of the gold-standard quantitative PCR. Clinical validation using 110 samples from bison and cattle demonstrated 100% concordance with PCR and complete differentiation from closely related species, including Mycoplasma canis and Mycoplasma felis. Overall, these data establish the RPA-CRISPR/Cas12a assay as a sensitive and specific isothermal approach for detecting M. bovis in clinical specimens, providing a field-adaptable framework for future instrument-free surveillance in resource-limited agricultural settings and supporting improved herd health management in both commercial cattle and bison conservation operations.},

abstract = {BACKGROUND: Neuroinflammation is a characteristic feature of many neurological diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. Uncontrolled activation of microglia and astrocytes results in the production of proinflammatory mediators that contribute to neuronal dysfunction and degeneration.

PURPOSE: CRISPR/Cas9 genome-editing technology provides highly precise targeting of genes involved in these pathways, enabling the deletion, correction, or modulation of disease-associated genetic alterations. Nonetheless, effective delivery of CRISPR components to the central nervous system (CNS) remains a major challenge because of protective barriers such as the blood-brain barrier (BBB), as well as concerns regarding genomic instability and immunogenicity.

METHODS: Nanotechnology-guided delivery platforms, such as lipid nanoparticles, liposomes, dendrimers and polymeric carriers, have been developed as promising strategies to address these challenges. These nanosystems can improve biodistribution, pharmacokinetic behavior, and cellular uptake, while potentially reducing off-target effects and systemic toxicity.

RESULTS: The preclinical studies demonstrate successful modulation of key neuroinflammatory targets, including the NLRP3 inflammasome, triggering receptor expressed on myeloid cells 2 (TREM2), Janus kinase (JAK) signaling, and the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway, with potential therapeutic relevance to neurodegenerative diseases. In addition, novel techniques, such as mitochondrial base editing, prime editing, and epigenetic modulation, expand the scope of CRISPR-mediated therapeutic strategies. Although outcomes from animal models are promising, translation to the clinical setting requires careful consideration of safety, ethical concerns, and long-term efficacy.

CONCLUSIONS: This review highlights the potential of integrating CRISPR/Cas9 with nanodelivery systems to advance precision medicine for neuroinflammatory disorders, while emphasizing their potential for therapeutic applications in complex CNS conditions. Ongoing studies aimed at optimizing delivery and reducing off-target effects will be essential for advancing these approaches toward clinical practice.},
