Mitochondrial oxidative stress is activated in M7 cybrids. (A) Mitochondrial ROS was determined in M8 and M7 cybrids by MitoSOX. Relative mitochondrial ROS levels were normalized to M8-1 cybrid. (B) Representative Western blot of mitochondrial quality control proteins, including GRP75, HSP60, LONP1, and CLPP, from whole-cell extracts of M8 and M7 cybrids. ACTIN was used as a loading control. Relative protein levels were normalized to M8-1 cybrid. Data are presented as the mean ± SD from at least 3 independent tests per experiment. *P < 0.05; **P < 0.01.
