Outline of Final Research Achievements |
In this study, we found the molecular interaction between full-length SREBF1 and ARMC5, the causal gene of bilateral macronodular adrenal hyperplasia (BMAH). ARMC5 recruited ubiquitin ligase complex containing CUL3 and ubiquitinated full-length SREBF1. In adrenocortical cells, ARMC5 regulated cholesterol synthesis and cell proliferation, which resulted in progression of BMAH.

Academic Significance and Societal Importance of the Research Achievements |
クッシング症候群の一部である両側性大結節性副腎皮質過形成の発症機構を明らかにし、その治療に貢献する可能性がある。また、SREBFは脂質合成やコレステロール合成を介して、肥満、脂肪肝、血中コレステロール濃度にも寄与しており、ARMC5を介したhealthy adipose expansion、脂肪肝、高コレステロール血症の制御にもつながる可能性があると考えられる。
