FIGURE 6.
Western blot. Protein kinase B (Akt) phosphorylation was increased in male and female trained animals in comparison with control counterparts. This alteration was more pronounced in exercised female exercised rats compared to male ones. We have not found any differences regarding the phosphorylation of p38 mitogen activated protein kinase (MAPK) and glycogen synthase kinase (GSK)-3β. Extracellular signal-regulated kinase (Erk) 1/2 (p42/44 MAPK) phosphorylation was decreased in female animals, and remained unaltered in male rats after the training program. Phosphorylation of mammalian target of rapamycin (mTOR) showed exercise-induced alteration only in female animals, while phosphorylation of S6 ribosomal protein was increased only in male exercised animals. MCo, male control group; MEx, male exercised group; FCo, female control group; FEx, female exercised group. Values are means ± SEM. ∗p < 0.05 vs. MCo, #p < 0.05 vs. FCo, pi: interaction p-value of two-way analysis of variance (ANOVA).
