Outline of Research at the Start

目的達成のために計画している研究項目は、(1)NRF2やHIF活性が変化するモデル動物を用いた網羅的解析、(2)システムバイオロジー解析によるバイオマーカー候補分子の選定、(3)疾患モデル動物を用いた実証研究の3つである。研究計画では、最初の2.5年間で、1)および2)を、残りの1.5年間で3)を完成させることになっている。2023年度までには、上記(1)のうち、NRF2活性が変化する薬理学的モデル動物を用いて1種類のmRNAを候補分子として発見している。HIFの活性化薬(PHD(プロリン水酸化酵素)阻害薬)を用いた解析では、鉄代謝に関与する分子を候補分子として見出している。

Outline of Final Research Achievements

Oxygen homeostasis in the kidney is maintained by two master regulators, including NF-E2-related factor 2 (NRF2) and hypoxia-inducible factor (HIF). Their activities detected by biomarkers (BM) are useful for early diagnosis of kidney disease. We searched BM reflecting NRF2 or HIF activity using urinary extracellular vesicles (exosomes). As a result, it was thought that obtaining reliable data for HIF would be difficult due to the inability to collect sufficient samples; however, it may be possible to detect NRF2 activity by using the Pirin gene in urinary extracellular vesicles. Based on these results, it is anticipated that future clinical studies will progress.

Academic Significance and Societal Importance of the Research Achievements

腎特異的な酸素状態の変化を非侵襲的に早期に検出する技術の開発は思いの外難しい。その理由は、全身性の酸素状態の変化との区別が容易でないからである。しかし、由来が腎細胞である細胞外小胞をソースとしたバイオマーカー(BM)を用いるとその問題をクリアできる。我々の、腎特異的な酸素状態の変化を細胞外小胞BMによって検出できる可能性を示す研究成果は、生理機構の破綻から発生する病態を描出する新技術であり、細胞外小胞バイオロジー分野に新しい視座をもたらす。加えて、人医、獣医両領域の腎臓病を克服するための早期診断法の開発において、重要な意義を持つ。
