The effects of carvones on the ligand-inducible expression of the prototypical AhR target gene CYP1A13 were examined in a complementary set of AhR-competent human cell lines, including primary human hepatocytes, HepG2 hepatocarcinoma cells, LS180 colon adenocarcinoma cells, and HaCaT immortal keratinocytes23. Here, AHR is linked to colon adenocarcinoma.
