Research Abstract

近年、SPAK/OSR1を制御する分子の変異により遺伝性の高血圧を発症することが明らかになった。これは、細胞の浸透圧応答とイオンバランスの制御がヒトの病態と深く関わることを示す一例である。本研究の結果得られた分子群により説明される浸透圧応答メカニズムはこのような病態の理解と治療に新たな道を拓くものになると期待できる。本年度は、ショウジョウバエのRNAiスクリーニング系の立ち上げ、脱リン酸化酵素など特殊な注目分子に限定したスモールスケールのスクリーニング、そして全ゲノムの網羅的なスクリーニングへと段階的に進めて、細胞レベルの浸透圧ストレス応答の受容、情報伝達、応答に関わる分子群を遺伝学的に同定した。特にS2細胞のRNAiスクリーニングでは、ASK3やSPAK/OSR1の活性制御に関与する分子が明らかになった。また、ターゲットを絞り込んだスモールスケールのスクリーニングを行い、全遺伝子スケールにおけるスクリーニングのために、ハイスループット化が可能な方法の開発を着実に進めることができた。
