AHR Gene Editing    

AHR (aryl hydrocarbon receptor) is a class of ligand-dependent transcriptional regulators and belongs to the basic helix-loop-helix (bHLH/Per-Arnt-Sim (PAS) protein family (Figure 1). In the absence of a ligand, AHR remains in the cytoplasm and forms a complex with the chaperone proteins HSP90, AIP (XAP2 or ARA9) and p23. Binding of the ligand results in a conformational change that in turn leads to AHR nuclear translocation. AHR releases from its partner and then binds to the bHLH/PAS domain transcription factor-AHR nuclear transporter (ARNT) to form a dimer, the AHR response element (AHRE), to regulate expression of the target gene (e.g. CYP1A1) (Figure 2).

As a conserved nuclear transcription factor, AHR is expressed in most human cell types, especially in the lung, thymus, kidney, and liver. The main function of AHR is to mediate toxic responses by regulating several metabolic-related enzymes, including cytochrome P450, glutathione S-transferase-α, NAD(P)H reductase-1, and UDP glucose aldehyde, glycosyltransferase. In recent years, AHR research has focused on its effects on inflammation and cancer. However, studies have found that AHR also plays a crucial role in regulating cell proliferation and survival. There is increasing evidence that AHR may regulate several growth factor signaling pathways to induce cell proliferation and survival.

As a conserved nuclear transcription factor, AHR appears to play many roles in cells. Therefore, there is still a need to learn more about the signaling pathways involved in AHR and the more potential functions of AHR.
