The effects of pretreatment of MitoQ or SKQ1 on Dox-induced cell viability reduction. The representative pictures of cells (100 X) after pretreatment are shown in A (scale bar: 50 μm). The effects of MitoQ and SKQ1 pretreatment on Dox-induced cell damage are illustrated in B. Higher doses of MitoQ or SKQ1 significantly improved cell viability when given as pretreatment. Moreover, MitoQ exerted significantly higher protection than SKQ1. *p < 0.05; **p < 0.01 vs Dox; ##p < 0.01 vs SKQ1
