Mitochondrial respiration of tBHP-treated H9C2 cells after the pretreatment of ginseng. Cultured H9C2 cells were treated as in Fig. 6. The basal respiration, proton leak, ATP production, spare respiratory capacity, maximal respiration, and nonmitochondrial respiration were measured. The OCR value was normalized with cellular protein/well by Bradford's method. Data are expressed as Mean ± SD, n = 3, each with triplicate samples. Statistical comparison was made with the sample with the lowest value of corresponding concentration, *p < 0.05, **p < 0.01, ***p < 0.001.
OCR, oxygen consumption rate; SD, standard deviation; tBHP, tert-butyl hydroperoxide.
