BSO+AUR affected antioxidant enzyme activity.

<p>A–C: FaDu and Cal-27 cells were treated with 0.5 µM AUR and/or 1 mM BSO for 24 h, then analyzed for glutathione reductase (GR) activity (A), glutathione peroxidase (GPx) activity (B), and peroxiredoxin activity (C). Error bars represent the standard error of the mean (SEM) of N = 3 experiments. *, p<0.05 versus control.
