Flt1 encodes Flt-1/VEGFR1, a high-affinity receptor tyrosine kinase for VEGF-A, VEGF-B, and PlGF that regulates vascular development, endothelial cell migration, and permeability. In mouse tissues, VEGFR1 modulates VEGF signaling flux through PI3K–AKT, MAPK/ERK, and PLCγ-associated pathways, acting in both pro-angiogenic signaling and ligand sequestration depending on receptor isoforms and cellular context. Flt1 activity influences vascular patterning, inflammatory cell recruitment, and tissue remodeling, linking it to models of pathological angiogenesis, ischemia-associated neovascular responses, and tumor microenvironment vascularization. Altered VEGFR1 signaling is also relevant to studies of retinopathy and developmental vascular defects where VEGF pathway balance is critical.
Flt-1/VEGFR1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Flt1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Flt1. 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 Flt1 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 Flt1-disrupted clones.
