Figure 7: The effect of mesuagenin C 3 on total intracellular GSH level. Pretreatment with mesuagenin C 3 dose-dependently aggrandized intracellular GSH level after H2O2 challenge in the NG108-15 cells. Values are means ± S.E. from at least three independent experiments. The asterisk indicated significantly different values from H2O2-treated cells (* ).
