Figure 9.
Effect of resveratrol (R), piceatannol (ROH), piceid (RG), ionising radiation, and their combinations on the glutathione peroxidase (GPx) activity of MCF-7 cells. GPx activity was measured after incubation of the cells for 48 h. Cells were treated with stilbene derivatives at concentrations of 5 μM (a) and 25 μM (b). The presented data are the average of three independent experiments, shown as the mean ± SD (two-way analysis of variance (ANOVA) followed by Tukey’s post hoc test, p < 0.05). The mean difference (*) was compared with the control and (#) with IR.
