| Research Abstract |
We studied anti-aging mechanism of exercise via protein acetylation. Aged rats were exercised on treadmill 60 min/day and 4 times per week, for 8 weeks. We analyzed changes of liver protein. 2D-DIGE (two-dimensional difference gel electrophoresis) showed 13 significantly changed protein spots (10 increased and 3 decreased) from a total of 662 spots. However, these spots were below two fold changes, and intensity of each spot was very weak. Protein acetylation of liver mitochondria decreased with age by western blot analysis with anti-acetyl lysine antibody, however, exercised rats increased acetylation of protein.
