Effect of whey protein concentrate (WPC), rapamycin, and their combination on the redox status of breast cancer cells. (a) Glutathione (GSH) levels in non-tumorigenic MCF-10A cells and MDA-MB-231 cells after incubation with 10 mg/mL WPC for 48 hours. Effect of 48-hour treatment with 10 mg/mL WPC, 1 μM rapamycin, and their combination on (b) GSH levels and (c) reactive oxygen species (ROS) content in MDA-MB-231 cells, displayed as representative flow cytometry histograms and (d) a bar graph indicating fold-change relative to control levels. Data represent the means ± SD from three experiments. *P < 0.05; n.s.: not significant.
