Outline of Final Research Achievements

This study presents biochemical and structural evidence that extracellular m6A is generated from modified-RNA catabolism and is a potent and selective ligand of adenosine A3 receptor. This study provides a framework for understanding the roles played by the complex pantheon of extracellular modified nucleosides.

Academic Significance and Societal Importance of the Research Achievements

RNA修飾の代謝産物が眼房水中や血液といった細胞外液に豊富に含まれていることを示した。その中でもN6-methyladenosine(m6A)が生体内で受容体を強力に活性化して生理作用・病的作用を起こすことを明らかにした。本研究成果により、新しい液性因子としてRNA修飾由来の代謝物が生体機能に関わることが示された。本研究成果が基盤となり新しい核酸医薬開発への発展が期待される。
