Fig. 1From: 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 cells when Dox or H2O2 were added to a fresh or 1-day-old medium. The representative pictures of 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 and C, respectively. Unlike H2O2, the effects of Dox were not significantly different when Dox was applied to fresh vs old medium. **p < 0.01 vs non-treated control; ##p < 0.01 vs fresh mediumBack to article page
