Outline of Research at the Start

本研究では、Forward Geneticsを遺伝性腎線維化疾患モデルiPS細胞由来の腎臓オルガノイド上で応用し、我々の開発した腎線維化を可視化できる腎臓オルガノイド技術を加えることで、腎線維化による間質尿細管障害の進展を制御する分子群の同定を行い、CKD進行を支配する因子を明らかにすることを目指す

Outline of Final Research Achievements

AMP sensing by AMPK and the molecular mechanisms underlying its dysfunction in CKD remained unclear. In this project, we elucidated and reported the mechanism of AMPKγ AMP binding control mediated by ULK1-mediated phosphorylation of the AMPKγ subunit and its dysfunction in CKD (Yanagi T, et al. Kidney Int. 2024). Additionally, we conducted pathophysiological elucidations and therapeutic development for NPHP1-deficient nephronophthisis models using kidney organoids, leading to the identification of new signaling pathways in renal fibrosis and the screening of potential therapeutic candidates (patent applying).

Academic Significance and Societal Importance of the Research Achievements

腎線維化に関わる因子としてエネルギー恒常性に関わるAMP活性化プロテインキナーゼ(AMPK)に注目した研究をすすめた。我々はAMPKのAMP感知/結合力が生理的に制御されていること、また、疾患によってこのAMP結合感知能が低下することで細胞/臓器のエネルギー恒常性が破綻することを発見し、学術的意義の強いものであった(Kidney Int.2024)。また、慢性腎臓病の新しい治療薬シーズの発見、NPHP1欠損ネフロン癆の新しい治療薬候補の発見にも至っており、社会的意義は大きい。
