Outline of Final Research Achievements |
Adrenomedullin (AM) is an endogenous peptide which exerts a variety of physiological effects. RAMP2 and 3 are receptor activity-modifying proteins that bind to AM’s receptor and regulate its function. In this study, using female RAMP3 knockout mice (RAMP3-/-), we analyzed pathophysiological roles of RAMP3 in postmenopausal obesity. Mice were performed ovariectomy (OVX) and fed a high-fat diet. RAMP3-/- exhibited greater obesity with adipose tissue weight gain, lower oxygen consumption, severer glucose-intolerance and fatty liver compared with wild-type mice. RAMP3-/- also showed downregulation of membrane-type estrogen receptor GPR30. These findings suggest that RAMP3 plays a key role in the regulation of metabolism, and its malfunction will lead to postmenopausal metabolic disorder.
