LGALS7 encodes galectin-7, a β-galactoside–binding lectin enriched in stratified epithelia that contributes to keratinocyte differentiation, cell–cell and cell–matrix interactions, and regulation of apoptosis. Galectin-7 modulates glycan-dependent signaling at the cell surface and within the cytosol, influencing pathways linked to epithelial homeostasis, stress responses, and inflammatory remodeling. Altered LGALS7 expression has been associated with dysregulated epidermal barrier function and context-dependent effects on cell survival and migration in epithelial pathologies, including cancer-relevant phenotypes. These properties make galectin-7 a useful node for investigating glycan-mediated signaling, epithelial development, and microenvironmental regulation of cell fate.
galectin-7 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LGALS7 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LGALS7. 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 LGALS7 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 LGALS7-disrupted clones.
