Fig. 1. Resveratrol upregulates TTS expression in BMDCs. (A), After IFN-γ (100 U/ml) treatment, the cells were harvested at the indicated times. (B), BMDCs were pretreated for 1 h in the absence or presence of resveratrol (25-50 μm) and incubated with IFN-γ (100 U/ml) for 18 h. The protein levels in the cell lysates were analyzed by Western blot analysis using the indicated antibodies. The mean and standard error values shown represent three independent experiments. ^* and ^*** represent significant differences at P ＜ 0.05 and P ＜ 0.001, respectively, compared with unstimulated cultures.
