LGALS3 encodes galectin-3, a β-galactoside–binding lectin that localizes to the cytoplasm, nucleus, cell surface, and extracellular milieu to regulate cell–cell and cell–matrix interactions. Galectin-3 modulates key processes including apoptosis resistance, cell adhesion and migration, endocytosis, and innate immune signaling through glycan-dependent scaffolding of receptors and integrins. It influences inflammatory and fibrotic programs by shaping macrophage activation and cytokine networks, and intersects with pathways such as MAPK/ERK, PI3K/AKT, NF-κB, and TGF-β signaling. Dysregulated galectin-3 expression is associated with tumor progression and metastasis biology, chronic inflammation, and fibrosis, making LGALS3 a useful node for mechanistic studies in immunology, oncology, and tissue remodeling.
galectin-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LGALS3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LGALS3. 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 LGALS3 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 LGALS3-disrupted clones.
