Here, we present a lentivirus-mediated CRISPR activation and interference (CRISPRa/i) platform for somatic gene modulation in the prairie vole brain. This system enables non-mutagenic, titratable regulation of gene expression in the adult brain without germline modification. Our dual-vector system includes one construct expressing dCas9-VPR (VP64-p65-Rta) referred to as CRISPRa or dCas9-KRAB-MeCP2 (Kruppel-associated box-methyl CpG binding protein 2), referred to as CRISPRi under a neuron-specific promoter, and a second construct delivering a U6-driven sgRNA (single guide RNA) alongside an elongation factor 1 alpha (EF1α)-driven mCherry reporter. We detail the design, production, and stereotaxic delivery of these tools and demonstrate their application by targeting four genes implicated in social behavior (<i>Oxtr, Avpr1a, Drd1,</i> and <i>Drd2</i>) across two mesolimbic brain regions: the nucleus accumbens and ventral pallidum. Gene expression analyses confirmed robust, bidirectional transcriptional modulation for selected targets, establishing a proof of concept for CRISPRa/i in this non-traditional model. The dual-vector design is readily adaptable to other gene targets, cell types, and brain regions, and can be multiplexed to provide a flexible and scalable framework for investigating gene function in behaviorally relevant circuits. These advances represent the first successful implementation of somatic CRISPRa/i in prairie voles and expand the genetic toolkit available for this species.</p>","PeriodicalId":73086,"journal":{"name":"Frontiers in genome editing","volume":"7 ","pages":"1602983"},"PeriodicalIF":5.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12162470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grain legumes have long been identified as a valuable nutritional source for humans. However, their significance extends beyond nutrition to global food security, reducing reliance on chemical fertilizers, improving soil health and increasing resilience to climate change. Recognizing their vital importance in nutrition and agricultural production, scientists have worked persistently to uncover new genetic traits in legumes, resulting in enhanced yields, improved nutritional value and increased stress tolerance. Recently, the availability of genomic resources for new traits in grain legume plants has greatly increased, laying the groundwork for the adoption of advanced breeding technologies. Gene editing has shown significant potential to improve crop outcomes. This review critically examines the latest developments in gene-editing techniques specific to major grain legumes, focusing on their application in enhancing legume crops with significant agronomic characteristics. The article also shows the potential advantages associated with these advancements. Over the years, advancements in technologies such as Transcription Activator-Like Effector Nucleases (TALENs), Zinc Finger Nucleases (ZFNs), Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR/Cas9), and the more recent Prime Editing technique have significantly contributed to genetic enhancements. These innovations have improved nutritional and market traits, boosted farming incomes, and increased the accessibility of affordable nutritious food, particularly in developing nations. Studies show that CRISPR/Cas9 is the most extensively applied gene editing technology in grain legumes. The advent of this technology has transformed genetic modification by offering exceptional precision and efficiency. This progress has enabled the creation of grain legumes that are more resistant to climate change and enhanced with improved nutritional content. Our research highlights that soybeans have been the primary focus of CRISPR/Cas9 gene editing efforts, surpassing any other grain legume, unlocking significant potential for innovation and improvement.

Due to their low prevalence, these diseases often attract limited research and commercial interest, leading to significant unmet medical needs. In a therapeutic landscape where treatments are targeted to manage symptoms, gene editing therapy emerges as a promising approach to craft curative and lasting treatments for these patients, often referred to as \"one-and-done\" therapeutics. CRISPR-dependent base editing enables the precise correction of genetic mutations by direct modification of DNA bases without creating potentially deleterious DNA double-strand breaks. Base editors combine a nickase version of Cas9 with cytosine or adenine deaminases to convert C·G to T·A and A·T to G·C, respectively. Together, cytosine (CBE) and adenine (ABE) base editors can theoretically correct ∼95% of pathogenic transition mutations cataloged in ClinVar.
