Abstract

Sarcopenia, age-related muscle atrophy, weakening muscle strength, and exercise capacity, generally accompany imbalances in protein metabolism. Chrysanthemum morifolium Ramat. extract (CME) and its active compound, isochlorogenic acid A (IcA), have been reported to have anti-oxidative, anti-diabetic, and neuroprotective effects. However, the roles of CME and IcA in the regulation of muscle protein turnover-related signaling pathways to attenuate sarcopenia have not been explored. In this study, we investigated CME and IcA based regulation of protein turnover in synthesizing muscle in vitro and in vivo. At the molecular level, CME and IcA promoted phosphorylation of PI3K/Akt and mTOR pathways, which stimulate synthesis of muscle proteins, and suppressed FoxO3a and E3 ubiquitin ligases during protein degradation. In vivo, CME and IcA increased grip strength, exercise capacity, muscle mass and volume, and cross-sectional area of myofibers in middle-aged C57BL/6J mice. These results suggest that CME and IcA may have roles as functional food supplements for delaying sarcopenia by enhancing muscle mass recovery and function.
