Fig. 4. Effects of genistein and 17β-estradiol on cell viability (A) and mitochondrial membrane potential (B) in Huh7.5 cells in presence of tumor necrosis factor (TNFα). Data were normalized against the control value. G: genistein; E: 17β-estradiol. C=control (non-treated cells); FFAs=free fatty acids. Reported data are means ± SD of five independent experiments for each experimental protocol. Significance between groups: * P <0.05 vs. C; # P <0.05 vs FFAs; χ P <0.05 vs. TNFα.
