AHR and hepatocellular carcinoma: For this purpose, we incubated stably transfected human hepatoma AZ-AHR cells for 24 h with triptans (maximal tested concentrations were selected based on limited solubility of individual compounds) in the presence or the absence of diverse AhR agonists, including TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin), BaP (Benzo[a]pyrene) and FICZ (6-Formylindolo[3,2-b]carbazole).
