Effect of resveratrol and methylthiostilbenes on EGFR activation in HaCaT (a) and A431 (b) cells. Levels of the protein were assessed by Western blot analysis. Representative immunoblots and data (mean ± SEM) from three independent experiments run in duplicate are presented. β-actin was used as an internal control. The asterisk above the bar denotes statistically significant differences from the control cells (DMSO), p < 0.05
