Abstract
En 中文
• Autophagy is central to muscle health and declines with aging. • Spermidine counteracts aging by activating autophagy and extending lifespan. • Polyamine metabolism is activated during muscle regeneration and differentiation. • SMOX levels are elevated in healthy muscle and decreased in atrophic muscle. • Spermidine and exercise show synergistic anti-atrophic effects.
