Chlorogenic Acid Stimulates the Thermogenesis of Brown Adipocytes by Promoting the Uptake of Glucose and the Function of Mitochondria.
JOURNAL OF FOOD SCIENCE(2019)
Abstract
Brown adipose tissue (BAT) prevents obesity and related diseases by uncoupling oxidative phosphorylation with adenosine triphosphate. Previous studies have demonstrated that polyphenols can promote the thermogenesis of BAT in mice. Chlorogenic acid (CGA) is a common phenolic acid found in fruits and vegetables, as well as traditional Chinese medicine, which is responsible for a variety of physiological activities. However, it is still unclear whether CGA has positive effects on the thermogenesis of BAT. In this study, CGA enhances the thermogenesis and proton leak of brown adipocytes, however, no changes are evident regarding the differentiation of C3H10T1/2 into brown adipocytes. Surprisingly, CGA promotes the uptake of glucose by upregulating the glucose transporter 2 and phosphofructokinase. Moreover, CGA increases the number and the function of mitochondrial. Taken together, CGA stimulates thermogenesis of brown adipocytes by promoting the uptake of glucose and the function of mitochondria. Practical Application Chlorogenic acid (CGA) is widely found in fruits, vegetables, and traditional Chinese medicines, which has been considered to have antibacterial and anti-inflammatory function. However, whether it has the function of resisting obesity and promoting thermogenesis is still unclear. In this study, brown adipocyte was used to explore the function and mechanism of CGA on thermogenesis. It provides new ideas for the utilization of foods rich in CGA and traditional Chinese medicine.
