Figure 5From: The prosurvival role of autophagy in Resveratrol-induced cytotoxicity in human U251 glioma cells Effects of Res on alterations in mitochondria membrane potential. U251 cells were treated with Res (150 μM) for various lengths of time. Mean percentage of U251 cells stained green (FL 1-H) of all total cells was determined by flow cytometry. Results (mean ± SD) from 3 independent experiments were quantitatively analyzed. *, P < 0.05 compared to the control group.Back to article page
