Figure 5

Concentration-dependent ROS generation in GSE-treated oral cancer Ca9-22 cells. Ca9-22 cells were incubated with indicated concentrations of GSE (0–400 μg/ml) for 24 h. (A) Representative histograms of flow cytometric analysis on ROS levels from GSE-treated cells. (B) Quantitative analysis of ROS intensity by means of DCF positivity percentage. ROS is counted at the intensity of right gated region in (A). Data, mean ± SD (n = 3). Treatments with the same capital letter are nonsignificant.
