FGF5 encodes fibroblast growth factor 5 (FGF-5), a secreted ligand that signals primarily through FGFR1/FGFR2 with heparan sulfate as a cofactor to activate MAPK/ERK, PI3K–AKT, and PLCγ pathways. It contributes to regulation of cell proliferation, differentiation, survival, and extracellular matrix remodeling in development and tissue homeostasis. In skin and hair follicle biology, FGF-5 is a key regulator of anagen-to-catagen transition, linking it to hair growth phenotypes. Dysregulated FGF-5/FGFR signaling has been associated with altered growth factor networks in oncology and with aberrant wound repair and fibrotic remodeling contexts.
FGF-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FGF5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FGF5. 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 FGF5 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 FGF5-disrupted clones.
