Effect of cyproterone acetate (CPA) on the transactivation activity of the aryl hydrocarbon response element (AHRE) in mouse cells. Reporter plasmids, pAhRDtkLuc3 and RSV-lacZ, were transfected into Hepa-1c1c7 cells. (a) Hepa-1c1c7 cells were treated with CPA (30 μM) for 2–8 h. (b) Hepa-1c1c7 cells were treated with CPA (10, 20, 30, 60, and 90 μM) for 6 h. (c) Hepa-1c1c7 cells were pretreated with 10 μM CH-223191 (CH) for 1 h, followed by treatment with 30 μM CPA and 1 μM β-NF for 6 h. At the end of incubation with the test compounds, cells were harvested, and cell lysates were collected for an activity assay of luciferase and β-galactosidase. Results are expressed as the mean ± SD, n = 3. **p < 0.01, and ***p < 0.001.
