HIF1A encodes hypoxia-inducible factor 1α (HIF1α), a central oxygen-sensing transcription factor that accumulates under low oxygen and drives adaptive gene programs controlling glycolysis, angiogenesis, erythropoiesis, and cell survival. Stabilized HIF1α heterodimerizes with ARNT (HIF1β) and binds hypoxia-response elements to regulate targets such as VEGFA, SLC2A1, and LDHA, integrating signaling from PI3K–AKT–mTOR, MAPK, and mitochondrial ROS. Under normoxia, prolyl hydroxylation promotes VHL-mediated ubiquitination and proteasomal turnover, coupling oxygen availability to transcriptional output. Dysregulated HIF1A/HIF1α activity is implicated in tumor hypoxia biology, ischemia-related stress responses, inflammation, and metabolic reprogramming, making it widely used in pathway and disease-model research.
HIF1a Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HIF1A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HIF1A. 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 HIF1A 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 HIF1A-disrupted clones.
