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.

Academic Significance and Societal Importance of the Research Achievements |
閉経後の女性では、内臓脂肪型肥満、インスリン抵抗性、脂質代謝異常など、心血管病のリスクが著しく増加する。閉経後のエストロゲンの減少が、その基盤となることが示唆されており、ホルモン補充療法の効果が期待されるが、副作用などの問題から、新たな治療の登場が望まれている。 アドレノメデュリン(AM)は多彩な生理活性を有する内因性ペプチドである。本研究では、AMの受容体活性調節タンパクであるRAMP3と、閉経後代謝障害係や膜型エストロゲン受容体GPR30との関係が明らかとなり、治療標的として有望であることが示された。これらの研究成果は、将来的に加齢性疾患の性差医療につながることが期待される。
