Real-time quantitative PCR analysis of the gene expression in MCF7 and HepG2 cells. Fold changes was calculated for MAPK1, MDR1, MMP9, TIMP1, Nrf2, HO-1, VEGF, and TNFα genes. Values are given as mean ± SEM (n = 3/group). Various letters [a (highest value)–f (lowest value)] denote significant differences at P < 0.05. All groups were compared to each other
