Outline of Final Research Achievements

In this study, we investigated the pathophysiology of polyPR peptide, produced from ALS-causative C9orf72 gene, and the treatment methods through comprehensive analysis of proteome and cytotoxic pathways. As a result, we found that polyPR accumulated in nucleoli and inhibited protein translation, and caused phase separation to inhibit the function of many proteins. In addition, we have identified a compound that suppresses the production of polyPR and we are continuing the experiments for future clinical application.

Academic Significance and Societal Importance of the Research Achievements

我々はALSの最も重要な原因遺伝子であるC9orf72遺伝子産物polyPRの毒性機構解析を行い、特異的に核小体に集積し、蛋白翻訳抑制を介して神経細胞死を起こすことを見出した。本知見は様々なグループから追試されており、蛋白翻訳抑制はpoly-PRによる毒性機構として広く認知されている。また、今回同定したpolyPRの産生を抑制する化合物はすでに他疾患で臨床応用に向けた治験が進んでおり、臨床化されればその社会的意義は極めて大きい。
