Outline of Final Research Achievements |
Activation of brown/beige adipose tissue has been suggested as a therapeutic strategy for metabolic disorders. While activation of brown/beige adipose tissue is associated with mobilization of both glucose and lipids, few studies have focused on the role of glycolytic enzymes in regulating adipose tissue function. We generated mouse models with specific deletion of the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1) from adipose tissue. Our results suggest a cell-autonomous mechanism, in which inhibition of glycolysis leads to beiging of visceral WAT secondary to downregulation of autophagy by mTor. Targeting this mechanism is potentially a novel therapeutic strategy for obesity and diabetes.
