Brown adipose tissue (BAT) has long been recognized as an energy-consuming organ and a possible target for combating metabolism disorder. Although numerous studies have demonstrated the ability of phytochemical phenolic acids to improve obesity by activating BAT, the underlying mechanism or mechanism therein remain obscure. In this study, diet-induced obese mice, genetically obese mice, and C3H10T1/2 cells were used to examine the effects of p-Coumaric acid (CA) on metabolism profiles. The results showed that CA prevented metabolic syndromes in the two mice models through the activation of BAT. This phenomenon was closely linked to the upregulation of uncoupling protein 1 (UCP1) and the accelerated burning of fatty acids and glucose, which consequently enhanced the energy expenditure and thermogenesis. Similar results were also obtained in vitro. Importantly, these effects were mediated by the mammalian target of rapamycin complex 1 (mTORC1)-RPS6 pathway. These findings reveal, to the best of our knowledge for the first time, the close correlation between mTORC1-RPS6 and BAT-mediated thermogenesis, and, in addition, the key role played by mTORC1-RPS6 in mediating phenolic acids-induced activation of BAT, thus preventing obesity.
