The MCF-7 cell viability under the effect of 5 (a) or 25 μM (b) of resveratrol (R), piceatannol (ROH), and piceid (RG) alone and in combination with ionising radiation (IR) (dose of 2 or 6 Gy) was determined using an MTT test after 48 h of incubation. All results are presented as the mean ± SD of three independent repetitions. Treatments were compared by a 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.
