FOXA3 encodes hepatocyte nuclear factor 3 gamma (HNF-3γ), a forkhead/winged-helix transcription factor that regulates chromatin accessibility and coordinates tissue-specific transcriptional programs during endoderm development. In differentiated cells, HNF-3γ contributes to liver and gastrointestinal epithelial gene networks controlling glucose and lipid metabolism, xenobiotic handling, and secretory function through interactions with nuclear receptor and hepatocyte transcription factor pathways. Altered FOXA3 expression or regulatory circuitry has been linked to dysregulated metabolic homeostasis and lineage-state changes observed in hepatobiliary and gastrointestinal disorders, making it a useful node for studying transcriptional control of cell identity. FOXA3 is also used as a marker and modulator in reprogramming and differentiation models where pioneer factor activity shapes enhancer and promoter usage.
HNF-3γ Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FOXA3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FOXA3. 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 FOXA3 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 FOXA3-disrupted clones.
