Effect of 3 weeks of exercise training on ecSOD, Cu/ZnSOD, and eNOS protein expression in aortas of C57BL/6 mice and eNOS^–/– mice. (a) Western analysis of ecSOD protein, Cu/ZnSOD protein, and eNOS protein in aortas of C57BL/6 and eNOS^–/– mice. Both untrained (sham) mice and mice exposed to 3 weeks of exercise training were studied. Twenty micrograms of mouse aorta from C57BL/6 was used as a positive control (PC). Western analyses were performed as described in Figure 6. (b) Densitometric analysis of a. Data are mean ± SEM for n = 6 (C57BL/6) and n = 3 (eNOS^–/– mice [strain A]). The data from eNOS^–/– strain B mice (n = 3) showed similar results. ^AP < 0.01 versus control cells.
