NQO1 and HO-1 are induced by the AHE and its fractions in HCT116 cells. (A) Measurement of AHE-induced QR activity in HCT116 cells. The cells were treated with the indicated concentrations of the AHE (0–200 μg/mL) for 24 h. (B) Measurement of butanolic fraction of AHE (AHB)–induced QR activity in HCT116 cells. The cells were treated with the indicated concentrations of the AHB (0–200 μg/mL) for 24 h. Each value represents the mean±SD from three independent experiments. NQO1 (C) and HO-1 mRNA expression (D) in response to treatment with the AHE or AHB in HCT116 cells. The cells were treated with 25, 50, 100, and 200 μg/mL of the AHE or AHB for 24 h. The results represent the mean±SD; n=3. Asterisks denote significant differences compared to the control (*P<.05; **P<.01).
