Filter by:Skeletal muscle stem cells (Satellite cells) are indispensable for muscle growth and remodeling following myofibril damage. Skeletal muscle trauma is present in numerous catabolic conditions, characterized by elevated proteolysis and muscle wasting such as, cancer cachexia and muscular dystrophy, which result in physical capacity impairment and a deteriorated quality of life. Recent studies performed in animals and cell cultures indicate that the increased levels of inflammation and oxidative stress and the reduction of antioxidant defense may blunt the satellite cells response and myogenic programming during muscle healing. However, evidence regarding the effects of redox status on satellite cells and muscle myogenic potential in humans is lacking. Exercise-induced muscle damage bears striking similarities with the aforementioned conditions, which makes it a valuable tool to investigate the redox-dependent regulation of satellite cells during muscle healing. Thus, the objectives of the present study are to examine the effects of redox status perturbation (via N-acetylcysteine administration) on intracellular pathways responsible for satellite cells responses at rest and following aseptic muscle trauma induced by damaging exercise.
This research will investigate the hypothesis that resveratrol when given orally to healthy adult smokers induces a decrease in the inflammatory and oxidative mediators which characterize the low-grade systemic inflammatory state and the oxidants-antioxidants imbalance of tobacco users.
