Outline of Final Research Achievements |
Primary aldosteronism (PA) is the most frequent cause of secondary hypertension. The diagnosis and treatment of PA are extremely important because excess aldosterone secretion not only causes hypertension but is also associated with a high rate of cardiovascular and renal dysfunction. In this study, we aimed to elucidate the mechanism of aldosterone synthesis via cell adhesion factors and intercellular signaling, which have not been focused on so far. We selected candidate factor A by single-cell analysis of aldosterone-producing adenoma (APA). Analysis is currently underway to infer the mechanism of aldosterone synthesis and APA tumorigenesis.

Academic Significance and Societal Importance of the Research Achievements |
30歳以上の日本人男性の60%,女性の45%以上が高血圧と言われ、また高血圧患者の5-10%程度を原発性アルドステロン症 (PA) が占めることから、PAは極めて頻度の高い疾患である。PAはアルドステロンを過剰分泌することにより、高血圧を来すだけではなく心血管疾患や腎機能障害を高率に合併するため、その診断・治療は極めて重要である。本研究ではこれまで着目されていない機序を介したアルドステロン合成機構に関与する候補因子を選抜し、PAの新しい治療戦略の開発に役立つ可能性がある。
