Effects of D on HO-1 expression and HO activity in PC12 cells. (a) Cells were incubated with various concentrations of D for 24 h. (b) Cells were incubated for indicated periods with 10 μM of D. Expression of HO-1 was determined by Western blot analysis, and representative blots of three independent experiments are shown. (c) HO activity was determined via bilirubin formation at 24 h after treatment with various concentrations of D. (d) PC12 cells were treated with 10 μM of D, and HO activity was measured at the indicated time points. Each bar represents the means ± SD of three independent experiments with triplicates. compared with control. compared with control. compared with control.

Effects of D on Nrf2 nuclear translocation in PC12 cells. Cells were treated with 10 μM D for 0, 1, 3, and 6 h, after which the nuclear (a) and cytosolic (b) Nrf2 proteins were determined by Western blot analyses. Data shown represent the means ± SD expressed as fold of 0 h group values obtained from three separated experiments with triplicates. compared with 0 h group. compared with 0 h group.
