mRNA expression (A) and activity (B) of glutathione peroxidase (GPX) is induced by exercise training but not by TNF-α.

<p>Expression and activity of catalase is not influenced by exercise training or TNF-α administration (C; D). The activity of total superoxide dismutase (SOD) and manganese superoxide dismutase (Mn-SOD) is not affected by exercise training or TNF-α administration (E, F). *p<0.01 vs. sedentary+NaCl, §p<0.05 vs. sedentary+TNF-α, n = 10 per group.
