Outline of Final Research Achievements

Treatment with 2-deoxyglucose, a glycolysis inhibitor, mitigated bilateral renal ischemia-reperfusion injury. It was because 2-deoxyglucose promoted beta oxidation of free fatty acids and pentose phosphate pathway in renal tubule cells, which resulted in an increase in intracellular ATP.
In addition, we showed that Mint3 mitigated fibrosis in murine chronic kidney disease by inducing anti-apoptotic molecules via NF-κB up-regulation.

Academic Significance and Societal Importance of the Research Achievements

慢性腎臓病には根本的治療がなく,そのため透析導入などに繋がっている.そこで慢性腎臓病の進行に関わる炎症についてその機序の解明を目指し,主に二つのことを見出した.一つは,解糖系の阻害により腎尿細管細胞の代謝を変容させると,腎障害を軽減しうることである.二つめは,Mint3という分子がNF-κBを介してアポトーシスという細胞死を抑制することで,尿細管傷害を減弱し,慢性腎臓病の線維化を抑制することである.これらのことから,マクロファージなどの炎症細胞だけでなく,炎症を惹起する尿細管細胞などの上皮細胞傷害も炎症に重要な役割と果たすことが明らかとなった.
