Outline of Annual Research Achievements |
次世代シーケンサー(NGS)を効率的に用いて転写サイクルの解明に資するゲノムアッセイを行うことを目的に研究を進めている。平成26年度は、導入したIon Protonの稼働率を向上させ班内連携を進めた。スタンダードタイプとデスクトットタイプのNGS特性に合わせた効率的な解析フローを確立させ解析を進めている。転写サイクル異常に関わる疾患として解明を進めているCoffin-Siris症候群はBAF複合体の5つのサブユニットをコードするいずれかの遺伝子の突然変異が原因であることを、本研究において突き止めたが、さらに解析を継続して、あらたな原因遺伝子であるSOX11の突然変異を2例で同定した。この変異は、HMGドメイン内に存在し、構造解析やin vitroの機能解析で明らかな病的効果を示した。さらにゼブラフィッシュを用いたsox11のノックダウン解析とレスキュー実験においてCoffin-Siris症候群に類似した小頭症、脳細胞のアポトーシス等が出現し、ヒトSOX11のmRNAで一定のレスキュー効果を見出した。SOX11はBAFの下流に位置する転写因子で脳プロげニター細胞の維持や分化と関連することが明らかにされている。

Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
平成26年度は、Coffin-Siris症候群に関するあたらな原因遺伝子のSOX11の同定に成功した。SOX11はBAF複合体の下流に位置する転写因子でこれら一連の遺伝子異常が、類似の臨床症状を呈していることが大変興味深い。またこれら一連の研究が、転写サイクル研究に資すると考える。
|
Strategy for Future Research Activity |
次世代シーケンサーを用いた技術開発研究とともにヒト疾患に関わる転写サイクル関連因子の異常の同定を積極的に進める予定である。現在様々な疾患の解析も進めており、その一部に転写サイクルに密接に関連する分子の異常を呈しており、機能面を含めた解析を進める予定である。
