Resumen del estudio

Further studies showed that IQ promoted IRβ/AKT-related insulin signaling, mTOR/S6K1-mediated protein synthesis, and AMPK/PGC1α-driven mitochondrial function pathway in skeletal muscle (all p < 0.05) and C2C12 myotubes (all p < 0.05). Additionally, IQ (400 mg/kg) treatment effectively reduced colon inflammation (2.58-fold lower of IL-1β) and gut barrier permeability (1.66-fold lower of ZO-1), as well as reshaped gut microbial community and modulated bile acid composition in obese mice. Overall, these results provide novel evidence that IQ supplementation has the potential for mitigating obesity-related muscle
