Figure 3. Cell viability is affected by H2O2 via activation of the Fas/FasL pathway. Viability of cells pretreated with Kp7–6, a Fas/FasL antagonist, or vehicle and treated
for 2 h with or without H2O2. Results shown as mean ± standard error of the mean (SEM; n=5). Asterisk indicates significant effect of Kp7–6 preventing
cell death caused by H2O2 (one-way ANOVA and the Student–Newman–Keuls (SNK) test; p<0.001).
