Effects of caffeine on AhR transactivation. HepG2 cells were transfected with a luciferase construct (pGudLuc1.1) and β-galactosidase expression plasmid. The transfected HepG2 cells were treated with vehicle (DMSO), caffeine, or 3-MC (0.5 μM) for 24 hr, and luciferase assay was performed. Results represent fold changes in luciferase activity by drug treatment relative to vehicle treatment (mean ± S.D.; n = 3). *, p < 0.05 compared with vehicle-treated group.
