Keywordsクロマチン / ヒストン置換 / H3t / 精子形成
Outline of Research at the Start

精子形成過程では、「次世代へ伝播される遺伝情報」を形成するためクロマチン構造の再構成が起こる。この過程で起こる精子形成固有の現象が、体細胞型のヒストンから精巣特異的ヒストンへの置換である。我々はこれまでに、精子細胞には複数の機能未知のヒストンが発現しており、そのうちヒストンH3tは精子形成の最初期に必須であることを報告し、精子形成過程ではH3tを起点に従来の知見を超えた多彩且つ複雑なヒストン置換が起こっている可能性が高いことを示した。そこで、本研究では、体細胞型ヒストンから精子特異的ヒストンバリアントH3tへの置換を起点として、精子形成過程でのクロマチン構造変換とその制御機構の解明を目指す。

Outline of Final Research Achievements

We used ChIL-seq to evaluate the behavioral changes in the location of H3t incorporation into genome during spermatogenesis. Visualization of H3t localization in spermatogonial cells revealed that H3t formed a domain and H3.1/2 localized around it in many cases. The somatic histone H3.1/2 was incorporated into the genome before meiosis, suggesting that H3t functions during meiosis by replacing somatic histone H3.1/2.

Academic Significance and Societal Importance of the Research Achievements

これまでに精巣特異的に発現するヒストンバリアントの同定とその機能解析が行われてきたが、その多くがプロタミン置換などの精子形成過程の後期に関与していることが報告されている。一方で、ヒストン修飾酵素の研究により、減数分裂期に必須の酵素などが同定されている。本研究成果は精子形成の初期に機能しうるヒストンバリアントが作るクロマチン構造の存在が明らかとなった。これまでのヒストン修飾酵素などの知見と相俟って、生殖細胞形成におけるクロマチン動態の全容解明の一助となった。
