Outline of Research at the Start

近年、心不全とアミノ酸代謝異常の関連が報告されている。申請者らは、核酸分解の律速酵素であるAMP deaminase(AMPD)3が糖尿病心筋で増加し、ATP欠乏から心不全発症に寄与することを報告した。AMPD3は骨格筋においてアミノ酸代謝を制御している。本研究では心筋におけるアミノ酸代謝の分子機構と、その制御異常の心不全病態形成における役割を、特に核酸代謝との連関に注目して解明する。

Outline of Final Research Achievements

We discovered that BCKDH, a rate-limiting enzyme in branched-chain amino acid metabolism, localizes not only to mitochondria but also outside mitochondria in cardiomyocytes and that AMPD3, a rate-limiting enzyme in the purine nucleotide cycle, regulates its activity. Furthermore, we found that the imbalanced expression of BCKDH and AMPD3 occurs in diabetic myocardium, which may contribute to impaired energy metabolism in diabetic hearts.

Academic Significance and Societal Importance of the Research Achievements

心不全の病態形成において、BCAA代謝不全の関与が近年示唆されているが、その分子機序は明らかでない。本研究で見出した心筋細胞におけるBCAA代謝の新たな制御機構は、BCAA代謝を標的とした心不全の新規治療法の開発に寄与する可能性がある。高齢化社会を背景に心不全は増加の一途をたどり、治療法の限られた予後不良な疾患である。心不全の発症や重症化を予防する治療法の開発を目指した研究は、社会的意義も大きい。
