Insulin-like growth factor binding protein 4 (IGFBP4) is a secreted modulator of IGF-I and IGF-II bioavailability that regulates receptor engagement and downstream PI3K–AKT and MAPK signaling, shaping cellular proliferation, survival, and differentiation programs. By binding IGFs in the extracellular milieu, IGFBP4 can tune growth factor gradients and paracrine/autocrine responses within tissue remodeling contexts, including vascular and stromal microenvironments. Altered IGFBP4 expression or processing has been associated with dysregulated growth signaling observed in fibrosis, metabolic dysfunction, cardiovascular remodeling, and multiple cancer-related phenotypes. Consequently, IGFBP4 is frequently studied as a context-dependent regulator of IGF axis activity and extracellular signaling dynamics.
IGFBP4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IGFBP4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IGFBP4. 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 IGFBP4 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 IGFBP4-disrupted clones.
