Human VEGFD encodes VEGF-D, a secreted member of the VEGF family that regulates lymphangiogenesis and angiogenesis by engaging VEGFR-3 (FLT4) and VEGFR-2 (KDR). Proteolytic processing increases receptor binding and promotes endothelial cell migration, survival, and vessel remodeling through downstream PI3K–AKT, MAPK/ERK, and PLCγ signaling. VEGF-D–dependent signaling contributes to lymphatic vessel development, tissue fluid homeostasis, and immune cell trafficking in the tumor microenvironment. Dysregulated VEGF-D expression or pathway activity has been associated with altered lymphatic remodeling and metastatic dissemination in multiple cancer contexts, as well as inflammatory and edematous phenotypes relevant to vascular biology research.
VEGF-D Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the VEGFD locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within VEGFD. 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 VEGFD 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 VEGFD-disrupted clones.
