Outline of Final Research Achievements

Precise mechanism of repeat-associated non-AUG (RAN) translation remains obscure. Selective inhibition of RAN translation would be a therapeutic target for C9orf72 FTLD/ALS.
In this study, we identified a candidate regulator of RAN translation. Ever since its identification, we have performed validation experiments from multiple aspects if the candidate indeed modulates RAN translation. Current experimental results support our conclusion.

Academic Significance and Societal Importance of the Research Achievements

前頭側頭葉変性症という行動や言語の障害を引き起こす病気の仕組みを明らかにしようとする研究です。前頭側頭葉変性症の一部では、遺伝子上の特定の配列が異常に長く繰り返されることが原因となっている場合があり、この配列は未解明の特殊なメカニズムで毒性を持ったタンパク質へと翻訳されています。この研究では、細胞負荷の観点から、この特殊な翻訳の調整メカニズムの一端を明らかにし、将来の治療法開発の基盤となる知見を得ました。
