The ligand-activated transcription factor Aryl Hydrocarbon Receptor (AHR) regulates cellular detoxification, proliferation, and immune evasion in a range of cell types and tissues, including cancer cells. In this study, we used RNA-seq to identify the signature of AHR target genes regulated by the pollutant 2,3,7,8-tetrachlorodibenzodioxin (TCDD) and the endogenous ligand kynurenine (Kyn), a tryptophan-derived metabolite. This approach identified a signature of six genes (CYP1A1, ALDH1A3, ABCG2, ADGFR1, and SCIN) as commonly activated by endogenous or exogenous ligands of AHR in multiple colon cancer cell lines...
