Fig. 1

Skeletal muscle aging can increase insulin resistance by promoting mitochondrial dysfunction, IMCL accumulation, inflammation, oxidative stress, PTP1B expression, ER stress, decreased autophagy, sarcopenia and over-activated RAS. In addition, skeletal muscle mitochondrial dysfunction promotes IMCL accumulation and induces oxidative stress and ER stress, moreover, IMCL accumulation, oxidative stress, and ER stress can induce inflammation.
