From: Inhibition of human lung cancer cell proliferation and survival by wine
Effects of white wine on clonogenic survival of A549 cells. Cells were incubated with the indicated concentrations of white wine (Riesling), resveratrol or ethanol (to match the concentrations found in 2% white 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 of 3–5 individual experiments. RSV = resveratrol, **P < 0.01 vs. control.
