Gallic acid (GA) is a widespread naturally occurring phenolic acid and one of the main active monomers that forms polyphenols such as tannins. In recent years, GA has been found as a potential regulator in lipid metabolism. However, effects and possible mechanisms of GA on cell growth and lipid metabolism of bovine subcutaneous adipocytes remain unknown. In this study, we investigated whether GA could affect proliferation and adipogenesis of subcutaneous adipocyte in beef cattle. We found that GA possesses inhibitive effects on proliferation and adipogenesis of bovine subcutaneous adipocyte via activating the metabolic master factor AMP-activated protein kinase alpha (AMPKα) to promote programmed cell death and lipolysis. The findings prove GA is a key substance to inhibit proliferation and adipogenesis of bovine subcutaneous adipocyte in vitro. Further in vivo study needs conducted to verify the reductive effects of GA on subcutaneous fat in beef cattle.
