Selenium-mediated alleviation of skeletal muscle atrophy through enterotype modulation in mice.

Skeletal muscle is crucial for health, and glucocorticoid-induced atrophy poses a significant clinical challenge. This study utilized a dexamethasone (Dex)-induced mouse model to assess the impact of selenium supplementation on skeletal muscle atrophy during and after Dex treatment. Increasing evidence suggests the existence of a 'gut-muscle axis', where gut microbiota plays a regulatory role in muscle metabolism and function.
