Figure 3. Relative transcription levels of the pro-apoptotic genes cytochrome c and caspase 9 (A) and antioxidant molecules catalase (CAT), glutathione-disulfide reductase (GSR), glutathione peroxidase 1 (GPX), glutathione synthetase (GSS), and superoxide dismutase 1 (SOD1) (B). The analyses were performed using HepG2 cells exposed to the Arianor Ebony dye. Data are reported as means±SE from at least three independent experiments. *P<0.05, **P<0.01, ***P<0.001 compared to NC (one-way analysis of variance (ANOVA) followed by Dunnett's test). NC: negative control; PC: positive control.
