DCFH-DA assay. Intracellular Reactive Oxygen Species (ROS) in breast cells treated with (+)-pinoresinol (in a range from 0.001 – 100 μM) for 24 h under basal conditions a and after H2O2-induced oxidative stress b. Data are presented as the mean ± SEM of three independent experiments and *(for MDA-MB-231), † (for MCF7) and ∆ (for MCF10A) represent statistically significant differences (p < 0.05) with respect to the control, which was set as 100 %
