| Outline of Final Research Achievements |
We investigated the effect of Eicosapentaenoic acid on brown fat functions through one of its receptor, GPR120. GW9508, a specific GPR120 agonist, elevated brown fat specific genes including Ucp-1 in brown adipocytes. Knockdown of GPR120 or addition of MEK1/2 inhibitors canceled the activating effect of GW9508. Eicosapentaenoic acid might activate brown adipocytes through the GPR120 and MAPK pathway.
Morphological and gene expression analyses in perirenal adipose tissue in pheochromocytoma patients revealed that EHMT1, a histon methyltransferase, might play an important role for developing brown adipocytes in adult human.
