Effect of RSV treatment on the protein expression levels of antioxidant enzymes. The effect of RSV treatment (25 μM) for 72 h on the expression level of superoxide dismutase, catalase, and glutathione peroxidase in HEK293T (A), PC-3 (B), HepG2 (C), and MCF-7 (D) cells. Protein expression levels were determined by Western blot analyses. Expression levels were quantified by ImageJ software. Results are mean ± SEM (n = 3); RSV(−): non-treated; RSV(+): treated; **P ≤ 0.01 and *P ≤ 0.05, analyzed by one-way ANOVA and LSD post-hoc test.
