Outline of Research at the Start

本研究課題では、新たに開発されたゲノム編集技術(VIKING法)と生化学的手法を組み合わせることで、極微量の脂肪細胞由来の未知昇圧因子を同定し、その解析を行うことで肥満高血圧発症の分子機序解明を目的としている。この研究は、肥満高血圧の治療法開発のための分子基盤となり新たな創薬標的の提案や新規診断法の開発に繋がるのみならず、これまで同定不可能だった微量の活性因子の同定に応用されることが考えられ既存の研究アプローチを大きく変革・転換させる潜在性を有する。

Outline of Final Research Achievements

Hypertension is a frequently observed complication among obese patients with metabolic syndrome. In this study, we aim to identify the undetermined adipocyte-derived factor(s) that stimulate aldosterone synthase gene (CYP11B2) expression and aldosterone secretion that may induce obesity-related hypertension. We first differentiated mouse fibroblast 3T3-L1 cells into adipocytes, and collected their supernatants. The supernatants were incubated with human adrenocortical carcinoma H295R cells, and their CYP11B2 mRNA expression was measured by quantitative PCR with reverse transcription. The supernatants were then purified by anion-exchange chromatography and were further fractionated by LC-MS/MS. We then identified several candidate proteins and are investigating their function by shRNA.

Academic Significance and Societal Importance of the Research Achievements

本研究の遂行により、脂肪細胞由来の未知の液性昇圧因子の本態が初めて明らかとなるとともに新規創薬のターゲットが明確化されることから、本邦で2,700万人と推定されるメタボリック症候群・予備軍患者中に数多く存在する肥満高血圧患者の診断・治療に大きな福音をもたらす事が可能となる。特に、肥満高血圧患者において顕著な治療抵抗性高血圧に対しては、新規創薬・治療法の開発に向けて大きく貢献できると期待される。
