Relative levels of proteins involved in cell respiration. (A)—Cyc1, cytochrome c-1 (13.5 kDa, protein of the respiratory chain, located between complexes III and IV); (B)—Cox4i1, cytochrome c oxidase (16 kDa, protein of complex IV of the respiratory chain); (C)—ATP5a1, ATP synthase F1 (56 kDa, subunit of ATP synthase); (D)—Gapdh, glyceraldehyde-3-phosphate dehydrogenase (37 kDa, catalyzes one step of the glycolytic breakdown of glucose). * p < 0.05 compared with the static control mean. Typical Western blots for each protein were performed and are shown in the histogram. The data are presented as the mean ± standard error of the mean (M ± SE).
