Fig. 2From: Mitochondrial targeted antioxidants, mitoquinone and SKQ1, not vitamin C, mitigate doxorubicin-induced damage in H9c2 myoblast: pretreatment vs. co-treatmentEffects of Dox or H2O2 on H9c2 cell viability by a calcein staining assay when Dox or H2O2 were added to 1-day-old medium. The representative pictures of stained cells (100 X) after Dox or H2O2 incubation are shown in A (scale bar: 50 μm). Dose-dependent effects of Dox or H2O2 on cell viability are shown in B. Dox or H2O2 dose-dependently reduced cell viability. **p < 0.01 vs non-treated controlBack to article page
