CDH1 encodes E-cadherin, a Ca2+-dependent adherens junction protein that mediates homophilic cell–cell adhesion and maintains epithelial polarity and tissue architecture. Through linkage to β-catenin, p120-catenin, and the actin cytoskeleton, E-cadherin coordinates junctional remodeling, contact inhibition, and mechanotransduction, and it indirectly modulates Wnt/β-catenin signaling by influencing β-catenin availability. Disruption of CDH1 perturbs epithelial barrier integrity and promotes cellular dedifferentiation programs such as epithelial–mesenchymal transition, processes frequently studied in invasion, metastasis-associated phenotypes, and altered tissue morphogenesis. CDH1 loss or dysfunction is recurrent in epithelial cancers and is also implicated in hereditary diffuse gastric cancer, making it a key locus for investigating adhesion-dependent signaling and epithelial homeostasis in human models.
E-cadherin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CDH1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CDH1. 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 CDH1 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 CDH1-disrupted clones.
