Outline of Final Research Achievements

We have elucidated the mechanism of metabolic kidney disease, namely chronic kidney disease associated with metabolic disorders, including diabetes, dyslipidemia and obesity, focusing on the organ-organ associations. This study aimed to investigate pathophysiology of the disorders, introducing the new viewpoint, DNA damage response (DDR). As a result, DDR in the kidney causes metabolic alterations, and metabolic disorders also cause DDR alteration, which drives progression of CKD.

Academic Significance and Societal Importance of the Research Achievements

高齢化社会において増加する高血圧、糖尿病を背景に、慢性腎臓病は増加傾向にあり、代謝腎臓病の新たな治療戦略の開発は喫緊の課題である。本研究は、慢性腎臓病におけるDNA損傷とそれに伴って惹起されるエピゲノム変化が、代謝変化と双方向性に関与し合い、病態の進展をもたらすという新しいコンセプトを提案したものであり、学術的に新規性・独創性が高い。また、新規治療標的の候補分子を複数提案しており、疾患人口が増加する中で、社会的意義も大きいと考える。
