Human SNAI1 encodes SNAI 1, a zinc-finger transcriptional repressor that binds E-box motifs to suppress epithelial gene programs, including CDH1, and promote epithelial–mesenchymal transition (EMT). Through interactions with chromatin remodeling and co-repressor complexes, SNAI 1 reshapes transcriptional networks governing cell polarity, adhesion, migration, and developmental lineage decisions. SNAI1 activity is integrated with TGF-β/SMAD, Wnt/β-catenin, Notch, NF-κB, and hypoxia signaling, linking microenvironmental cues to phenotypic plasticity. Dysregulated SNAI1 expression is frequently associated with tumor progression, invasion and metastasis phenotypes, fibrosis-related remodeling, and altered stem-like programs, making it a relevant target for mechanistic studies of EMT and cellular state transitions.
SNAI 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SNAI1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SNAI1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt SNAI1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of SNAI1-disrupted clones.
