Polygonatum sibiricum Polysaccharides (PSP) Improve the Palmitic Acid (PA)-Induced Inhibition of Survival, Inflammation, and Glucose Uptake in Skeletal Muscle Cells

The underlying molecular mechanisms of PSP in improving insulin resistance (IR) in skeletal muscle remain unclear. PA induced an IR model in L6 myotubes. After treatment, cell proliferation was measured using the CCK8.
