Effect of red wine on survival of A549 cells. Cells were incubated with the indicated concentrations of red wine, resveratrol or ethanol (to match the ethanol in 2% wine-treated cells) for 7 days followed by fixing and staining with 0.05% methylene blue and colonies (> 50 cells) were counted. Results are expressed as the surviving fraction compared to untreated control. RSV = Resveratrol, *P < 0.05, **P < 0.01 vs. control.
