| Outline of Final Research Achievements |
This study examined the influences of exercise after right femoral arterial ligation on pro-angiogenic factors. Wild-type or Vitamin C knock-out mice were randomized groups (based on the presence/absence of ligation). The oxidative stress level was significantly higher at 1 W and 3 W in the <ligation with exercise> compared to Sham group. HIF-1α values were significantly higher at 3 W in the <ligation with exercise> and <ligation without exercise> compared to Sham group. The values representing the pro-angiogenic factors PGC-1α and IL-6 were significantly higher and those representing the anti-angiogenic factor endostatin were markedly lower in the <ligation with exercise> compared to Sham group. In a mice model of lower-limb ischemia, changes in the oxidative stress level were observed from 1 W. An increased HIF-1α level was also observed at 3 W. In this study, the balance between pro- and anti-angiogenic factors was clarified during a 6-weeks exercise program.
