Figure 1. Quercetin treatment could protect APRE-19 cells from the damage induced by H2O2.

Figure 1

RPE cells were treated with l.0 mM H2O2 with/without 50μM quercetin for 2 hrs and were then incubated with normal culture medium for 4hrs. (A) The cell viability was measured by crystal violet staining. (B) The mitochondrial function was measured by MTT assay. (C) The level of cellular apoptosis was measured by Comet assay. The severity of apoptosis was evaluated by the length of comet tails. Bars represent the mean ± S.E. of three independent experiments and indicate fold change relative to control cells. (*: p < 0.05)
