Effect of PTE pretreatment (24 h) on ROS production by H2O2 in dIMR32 cells. The data are expressed as mean ± SEM, n = 3. The label UT = untreated control cells. Statistical significance was analyzed with one-way ANOVA followed by Dunnett’s multiple comparison post-hoc test. Differences with p value less than p < 0.0001, p < 0.001 and p < 0.05 against 300 μM H2O2treatment were considered statistically significant. ****p < 0.0001, ***p < 0.001 and **p < 0.05
