Puerarin attenuates palmitate-induced mitochondrial dysfunction, impaired mitophagy and inflammation in L6 myotubes

High level of saturated fatty acids leads to mitochondrial dysfunction and inflammation in the development of insulin resistance in skeletal muscle. We recently found that puerarin improved impaired insulin signaling in skeletal muscle in diabetic animals and in myotubes in vitro. However, whether puerarin can act directly on muscle cells to alleviate lipid-induced mitochondrial dysfunction and inflammation remains obscure. This study was...
