Age- and Organ-Specific Differences in Mitochondrial Bioenergetics in Brown Norway Rats

Figure 4

Age-dependent changes in activities of Complex II (a) and Complex IV (b) enzymes in different organs. Values are expressed as means ± SEM from n = 5 observations/group. The differences between pairwise comparisons were considered statistically significant at . Significantly different from 1M rats; significantly different from 4M rats; ^Asignificantly different from lung; ^Bsignificantly different from liver; ^Csignificantly different from heart; ^Dsignificantly different from frontal cortex; SEM, standard error of the mean. Grey-scale bars represent frontal cortex data from our previous report (adapted from Pandya et al. [23], with permission).
