Figure 2From: The prosurvival role of autophagy in Resveratrol-induced cytotoxicity in human U251 glioma cells DNA flow-cytometric analysis of U251 cells after treatment with Res. The cells at the sub-G1 fraction were determined by DNA flow-cytometric analysis. Differences between control, UNT and 150 μM of Res treatment for 24 h or 48 h were observed; *, p < 0.001 (n = 6); data are presented as means ± SD.Back to article page
