Outline of Final Research Achievements |
We focused on the diversity of albumin molecules as a disease-progressing factor of the chronic kidney disease. We investigated 1) the molecular mechanism of skeletal muscle atrophy induced by uremic substances and 2) its therapeutic strategy, 3) the molecular mechanism of secondary hyperparathyroidism (SHPT)-induced hyperuricemia, and 4) the inhibition of CYP3A expression in SHPT, and 5) the molecular mechanism of renal tubular injury associated with renal fatty acid fluctuations, then found that indoxyl sulfate, parathyroid hormone and oxidized albumin were identified as negative humoral factors in chronic kidney disease. We also proposed a therapeutic target based on their molecular mechanism.

Academic Significance and Societal Importance of the Research Achievements |
慢性腎臓病(CKD)の場合、死亡や要介護状態の原因となる心血管疾患(CVD)や筋力低下(サルコペニア)・骨萎縮を合併しやすいが、既存の治療方法ではその進行を抑制できず、新たな治療戦略の構築が希求されている。本申請課題は、悪玉となる液性因子の探索と、それを基軸とした新規CKD個別化診断・治療戦略の道を拓く循環型のトランスレーション研究である。本研究成果はCKDを基軸とした多臓器連関に対する早期診断・治療に繋がるため、臨床的、社会的意義と波及効果は非常に高く、医療経済的観点からも緊急性は高いと思われる。
