After 24-hr treatment with various concentration of tBHQ, OCR was recorded by a Seahorse XFe96 flux analyzer (n=8). (A) OCR recording at baseline and subsequent treatment of 1μM oligomycin, 0.5 μM FCCP, and a 1 μM rotenone and antimycin mixture. Basal respiration (B), ATP production (C), maximum respiration (D) and spare capacity (E) were calculated. All experiments were repeated three times and the results indicate the mean ± SEM. *P < 0.05, ***P < 0.001, ****P < 0.00001 compared to control. (One-way ANOVA, Tukey’s test).
