Outline of Final Research Achievements

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension with autonomous excess aldosterone production. DNA methylation array and transcriptome analysis revealed VDR is the most associated factor related with Ca2+ homeostasis in aldosterone producing adenoma (APA). Immunohistochemical analysis showed VDR is strongly expressed in ATP1A1 mutated APA. These findings suggests VDR might associates with tumor growth and aldosterone production in ATP1A1 mutated APA.

Academic Significance and Societal Importance of the Research Achievements

高血圧患者の5-10%を占める原発性アルドステロン症(PA)は高血圧のみならず、心血管疾患や慢性腎臓病の合併率が高いが、PA患者におけるアルドステロン合成・分泌制御機構については充分に明らかにされていない。本研究において、ATP1A1変異をもつアルドステロン産生腫瘍ではVDRがアルドステロン合成及び腫瘍増殖に関与していることが示唆され、創薬標的因子の同定につながる可能性が期待される。
