%X Ectopic lipid accumulation in muscle is important not only for obesity and myopathy treatment, but also for meat quality improvement in farm animals. However, the molecular mechanisms involved in lipid metabolism in muscle satellite cells are still elusive. In this study, SB216763 reduced GSK3¦Â activation by increasing the level of pGSK3¦Â (Ser9) and decreasing the level of total GSK3¦Â protein. GSK3¦Â inhibition decreased lipid accumulation and downregulated the expression level of lipogenesis-related genes in the adipogenic differentiation of goat muscle satellite cells. Furthermore, SB216763 treatment increased the levels of pAMPK¦Á (T172) and pACC (Ser79). Further, we found that GSK3¦Â inhibition promoted levels of LC3B-II and reduced the protein levels of p62 to induce the autophagy in muscle satellite cells. Taken together, our results provide new insight into a critical function for GSK3¦Â: modulating lipid accumulation in goat muscle satellite cells through activating the AMPK pathway
