Localization of the Nrf2 protein and ARE gene activity in MODE-K cells with PC-induced concentrations and time gradients. (a) Cells were treated with 0, 1, 2.5, and 5 μg/mL PC for 24 h (40x). (b) Cells were treated with 5 μg/mL PC for 0, 3, 6, 12, and 24 h (40x). (c) Effects of PC on ARE gene activity in MODE-K cells. All tests were repeated at least three times. “” represents compared with the control group, and “” represents compared with the control group.
