Outline of Final Research Achievements |
In this study, we revealed that prostaglandin (PG) E2 promotes lipolysis in white adipose tissue via EP4 receptor by counteracting insulin signaling, and regulates lipid homeostasis and thermogenesis. Moreover, we found that this receptor modulates the quality of adipose tissue such as fibrosis and the capacity of lipid storage by stimulating collagen production.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、プロスタグランジン受容体による生体内の脂質代謝調節機構の一端が明らかとなった。また、今回の研究結果はマウスだけでなく、ヒトのSNPs解析においても再現されており、本研究で得られた知見を肥満や糖尿病、脂肪肝といった生活習慣病の治療や予防に応用できれば、その社会的意義は大きい。
