Outline of Final Research Achievements |
Protein arginine methyltransferase 1 (PRMT1) is involved in multiple cellular functions including differentiation and proliferation. PRMT1 is expressed in vascular endothelial cells (ECs), which are responsible for angiogenesis during embryonic development, but its role has remained elusive. In this study, we generated endothelial-specific prmt1-knockout (Prmt1-ECKO) mice, and found that they died before embryonic day 15. In these embryos, the superficial temporal arteries were poorly perfused with blood, and wholemount 3D imaging revealed dilated and segmentalized luminal structures in Prmt1-ECKO fetuses. Our findings provide evidence that PRMT1 is important for embryonic vascular formation.

Academic Significance and Societal Importance of the Research Achievements |
血管の障害は、様々な疾患の減となる。血管内皮細胞は、全ての血管に存在し、全身の臓器の形成や機能調節に不可欠である。近年、新たな血管制御のメカニズムとして、タンパク質の翻訳後修飾が注目されつつあるが、内皮細胞機能との関連は解明されていない。本研究では、アルギニン残基のメチル化を担う酵素PRMT1に着目して、内皮細胞でPRMT1をもたないマウスを作製したところ、胎児は早期に死亡し、血管網が脆弱であることが判明した。本研究成果は、タンパク質の翻訳修飾を制御することで、血管のメンテナンスや疾患の予防に繋がる可能性を示している。
