研究紹介

  1. 認知症における糖鎖関連遺伝子の発現変化を網羅的に解析し、どのような遺伝子が関与するかを明らかにします。また、Aβ産生機構と糖鎖の関連を解析し、新たな治療および予防法の開発を目指します。
  2. 老化モデルマウス(Klotho)における責任遺伝子産物の生理機能の解明を目指します。さらに、老化モデルマウスで得られた研究成果の自然老化マウスでの検証および老化関連疾患との関連性を明らかにします。
  3. 神経や筋肉における糖鎖の生理機能や生合成機構を解明し、老化や疾患に伴う変化の実体と病態との関連性を明らかにします。

生命の設計図であるゲノムの遺伝子情報は翻訳されてタンパク質が作られますが、半数以上のタンパク質はこのままではまだ働きが不十分で、そこにリン酸や糖鎖というものがくっついてリン酸化タンパク質や糖タンパク質となり初めて機能的に働きます。これをタンパク質の翻訳後修飾といい、生物のさまざまな機能にかかわっています。本研究グループは細胞どうしの認識や細胞内外の情報伝達において重要な役割を果たしているタンパク質の翻訳後修飾に焦点を当て、老化に伴う機能変化の解明および老化に伴う病態の解明を目指しています。
