The expression of p53, pFoxO-1 and MuRF1 protein in skeletal muscle during intensity endurance training.
ABSTRACT
The aim of this study was to investigate the expression of p53, p-FOXO-1, and MuRF-1 protein in the skeletal muscle of Sprague-Dawley rats during intensity endurance exercise (26 m/min, 10°, 15 min, 30 min, 45 min, 60 min, 90 min). The expression of p53, p-FoxO1, and MuRF1 protein in skeletal muscle by western blotting. The expression of p53, p-FoxO1, and MuRF1 protein significantly were increased at 15min to 30 min during intensity endurance exercise and then gradually returned to bofore exercise level. These finding suggest that p53, p-FoxO1, and MuRF1 protein plays a role in the maintennance of homeostasis in skeletal muscle during intensity endurance exercise.
Key words: Intensity endurance exercise, Sprague-Dawley rat, Skeletal muscle, p53, p-FoxO1, MuRF1
