Action of VA on ROS production and mitochondrial function. Intracellular ROS levels, Mitochondrial Membrane Potential and Mitochondrial Mass were analyzed in MCF-7 and MDA-MB-231 cells. The ratio between mitochondrial membrane potential and mitochondrial mass is also displayed. Untreated cells (C) were used as negative control. Values represent the mean of three triplicate independent experiments *p < 0.05 vs C. **p < 0.005 vs C
