Human APOA1 encodes apolipoprotein A-I, the major protein component of high-density lipoprotein (HDL) particles and a central mediator of reverse cholesterol transport. APOA1 interacts with ABCA1 and ABCG1 to promote cellular cholesterol and phospholipid efflux, driving nascent HDL biogenesis and supporting lecithin–cholesterol acyltransferase (LCAT)-dependent HDL maturation. Through these processes, APOA1 influences lipid homeostasis, macrophage foam cell formation, and inflammatory signaling in vascular and hepatic contexts. Altered APOA1 expression or function is associated with dyslipidemia and atherosclerosis-related phenotypes, making it a key target for mechanistic studies of lipoprotein metabolism.
Apolipoprotein A I/APOA1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the APOA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within APOA1. 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 APOA1 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 APOA1-disrupted clones.
