Human AHR encodes the aryl hydrocarbon receptor (Ah Receptor), a ligand-activated transcription factor that senses xenobiotics and endogenous metabolites to regulate gene expression programs controlling detoxification, barrier function, and immune modulation. Upon ligand binding, AHR translocates to the nucleus, heterodimerizes with ARNT, and binds xenobiotic response elements to induce targets such as CYP1A1 and CYP1B1, intersecting with oxidative stress responses and inflammatory signaling. AHR activity integrates with pathways including NF-κB, WNT/β-catenin, and TGF-β, influencing cell cycle control, differentiation, and tissue homeostasis. Dysregulated AHR signaling has been implicated in context-dependent tumor biology, chronic inflammatory states, and altered responses to environmental exposures, supporting its utility as a mechanistic node in toxicology and immunology research.
Ah Receptor Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the AHR locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within AHR. 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 AHR 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 AHR-disrupted clones.
