Comet assay. DNA oxidative damage in MDA-MB-231 a MCF7 b or MCF10A c after (+)-pinoresinol treatments expressed as Olive_TM (mean ± SEM). The comet assay was performed under basal and H2O2-induced injury conditions. Data are expressed as the percentage relative to the basal (untreated) control, which was set as 100 %. Statistically significant differences (*, † or ∆) were established relative to basal or H2O2-treated control (p < 0.05). d Representative comet assay images showing different treatments on MDA-MB-231, MCF7 and MCF10A cells
