Outline of Final Research Achievements

In this research project, we established the separation analytical method of the prostanoids by mass spectrometry and mass spectrometry imaging. As a result of examination using the tail-suspension model in in vivo, the data was shown that the production of prostanoid from the immune system cells participated in muscular atrophy. In the examination using the inhibitor of prostanoids production, an improvement effect of the muscular atrophy was observed. These data indicated that prostanoids regulated progression of muscular atrophy in the model of disuse diseases.

Academic Significance and Societal Importance of the Research Achievements

本研究課題の実施により、質量分析および質量分析イメージングによるプロスタノイドの解析基盤を確立した。さらに、廃用性筋萎縮の進行にはプロスタノイドが関与することを明らかとした。将来の廃用性筋萎縮やサルコペニア、ロコモティブシンドロームの治療につながる分子標的としてのプロスタノイド産生阻害剤の開発や遺伝子治療、天然由来機能性因子を活用し、新規な治療薬や治療因子の開発につなげてゆきたい。
