Outline of Research at the Start

慢性腎臓病を含む生活習慣病の新薬には、オルガネラ機能を改善し臓器保護効果を示すものが散見される。このことからオルガネラ相互作用を基軸にオルガネラ研究を更に発展させることは、新たな細胞機能維持機構やその破綻による病因論の解明、ひいては革新的な創薬標的分子の同定に繋がる。
本研究は、オルガネラ研究の中でも新研究領域であるオルガネラコンタクトサイト、特にmitochondria-associated membrane (MAM) に着目し、それらの尿細管における構造や生理活性、尿細管障害(代謝変動、炎症・線維化)との関連性などを分子レベルで解明し、腎臓病学に新たな展開をもたらすことを目指す。

Outline of Final Research Achievements

To assess pathophysiological role of organelle contact site in tubular homeostasis, plasma and urine samplers from diabetic kidney disease (DKD) patients and DKD model rats were examined by metabolomic and lipidomic analyses.
We identified Lysophosphatidylcholine(LPC) as a biomarker of fast decline in kidney function in DKD.
LPC accumulated in the proximal tubular cells decreased mitochondria-associated membrane (MAM) formation, in turn leading to organelle stress (endoplasmic reticulum and mitochondrial dysfunction) in association of metabolic alteration. Further, MAM-related gene expression is altered in tubular damage and linked to tubular phenotypic changes, such as tubular cell death and inflammation.

Academic Significance and Societal Importance of the Research Achievements

本研究は、小胞体、ミトコンドリアなどのオルガネラ研究を発展させ、オルガネラコンタクトサイト、特にmitochondria-associated membrane (MAM)に着目し、それらの腎臓における分子生物学的活性、腎臓細胞障害(代謝変動、炎症・線維化)との関連性などを解明することを目標とした。
一連の腎臓におけるオルガネラ研究、特にオルガネラコンタクトサイト研究の成果は、尿細管細胞恒常性、あるいは病態形成メカニズムを新たな視点から理解し、革新的な腎臓病病因論の確立に繋がることが期待される。
