ARNT (aryl hydrocarbon receptor nuclear translocator; HIF-1β) encodes a basic helix–loop–helix PAS transcription factor that functions as an obligate dimerization partner for AHR and hypoxia-inducible factors, including HIF-1α and HIF-2α. Through these complexes, Arnt 1 integrates xenobiotic sensing with oxygen and metabolic signaling to regulate transcriptional programs controlling detoxification enzymes, angiogenesis, glycolytic metabolism, mitochondrial adaptation, and cell fate decisions. ARNT-dependent gene regulation contributes to cellular responses to hypoxia and environmental ligands, with relevance to inflammation, barrier biology, and tumor microenvironmental adaptation. Dysregulated AHR/HIF pathway activity implicates ARNT in contexts such as carcinogenesis, metabolic disease mechanisms, and altered immune or vascular phenotypes, making it a key node for pathway dissection.
Arnt 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ARNT locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ARNT. 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 ARNT 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 ARNT-disrupted clones.
