However, the effects of FRG extract on muscle atrophy and the underlying molecular mechanisms remain unclear. This study aimed to elucidate the effects of FRG extract on muscle atrophy using both\n                    <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                    and\n                    <jats:italic toggle=\"yes\">in vivo<\/jats:italic>\n                    models. In vitro experiments used dexamethasone (DEX)-induced C2C12 myotubes to assess cell viability, myotube diameter, and fusion index. In vivo experiments were conducted on hind limb immobilization (HI)-induced mice to evaluate grip strength, muscle mass, and fiber cross-sectional area (CSA) of the gastrocnemius (GAS), quadriceps (QUA), and soleus (SOL) muscles. Molecular mechanisms were investigated through the analysis of key signaling pathways associated with muscle protein synthesis, energy metabolism, and protein degradation. FRG extract treatment enhanced viability of DEX-induced C2C12 myotubes and restored myotube diameter and fusion index. In HI-induced mice, FRG extract improved grip strength, increased muscle mass and CSA of GAS, QUA, and SOL muscles. Mechanistic studies revealed that FRG extract activated the insulin-like growth factor 1\/protein kinase B (Akt)\/mammalian target of rapamycin signaling pathway, promoted muscle energy metabolism via the sirtuin 1\/peroxisome proliferator-activated receptor gamma-coactivator-1\u03b1 pathway, and inhibited muscle protein degradation by suppressing the forkhead box O3a, muscle ring-finger 1, and F-box protein (Fbx32) signaling pathways. FRG extract shows promise for ameliorating muscle atrophy by modulating key molecular pathways associated with muscle protein synthesis, energy metabolism, and protein degradation, offering insights for future drug development.\n
