APOA4 encodes apolipoprotein A-IV (apoA-IV), an intestine-derived, lipid-associated apolipoprotein that is secreted with chylomicrons and HDL-like particles during dietary fat absorption. apoA-IV contributes to lipoprotein remodeling and reverse cholesterol transport and influences triglyceride-rich lipoprotein metabolism through interactions with enzymes and transfer proteins that regulate lipid flux in plasma. Through these activities it links intestinal lipid handling to systemic lipid homeostasis and inflammatory signaling associated with atherosclerotic processes. Variation in APOA4 expression or function has been investigated in the context of dyslipidemia, cardiometabolic traits, and lipid-driven inflammatory states relevant to vascular and metabolic disease mechanisms.
apoA-IV Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the APOA4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within APOA4. 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 APOA4 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 APOA4-disrupted clones.
