Outline of Final Research Achievements

m6A modification of lncRNA named pncRNA-D regulates cell cycle by controlling the expression of cyclin D1.
RNA is also methylated or acetylated, and this time I focused on the most abundant RNA modification, m6A. pncRNA-D is a long noncoding RNA transcribed from the promoter region of cyclin D1. m6A modification of pncRNA-D altered interaction with RNA binding proteins, and half-life of this RNA. in summary, I discovered m6A modification of pncRNA-D is deeply related with cell cycle and cell growth of cancer cell lines.

Academic Significance and Societal Importance of the Research Achievements

本研究では複数のがん細胞由来の細胞株の増殖を抑えるRNA修飾を発見した。これはつまり、がん細胞間で保存された細胞増殖メカニズムを抑制するRNA修飾であることを意味する。本研究をさらに進めると、多くのがん細胞の増殖を抑えられるRNA断片の作製に繋がることが期待される。
