Suppression of α/β-domain hydrolase-6 (ABHD6), a monoacylglycerol (MAG) hydrolase, promotes glucose-stimulated insulin secretion by pancreatic β cells. We report here that high-fat-diet-fed ABHD6-KO mice show modestly reduced food intake, decreased body weight gain and glycemia, improved glucose tolerance and insulin sensitivity, and enhanced locomotor activity. ABHD6-KO mice also show increased energy expenditure, cold-induced thermogenesis, brown adipose UCP1 expression, fatty acid oxidation, and white adipose browning. Adipose browning and cold-induced thermogenesis are replicated by the ABHD6 inhibitor WWL70 and by antisense oligonucleotides targeting ABHD6. Our evidence suggests that one mechanism by which the lipolysis derived 1-MAG signals intrinsic and cell-autonomous adipose browning is via PPARα and PPARγ activation, and that ABHD6 regulates adipose browning by controlling signal competent 1-MAG levels. Thus, ABHD6 regulates energy homeostasis, brown adipose function, and white adipose browning and is a potential therapeutic target for obesity and type 2 diabetes. |
