Outline of Research at the Start

複雑な細胞機能の理解を深めるためには,タンパク質や核酸などの機能性生体高分子の 時空間的な機能発現を系統立てて研究することが重要だ.しかし,細胞自身が生産する生 体分子を天然のままで解析可能な方法は少なく技術的に難しい.本研究では,採択者が開発した「機能性RNAと小分子化合物」を研究ツールとして利用し,哺乳動物細胞内でRNA機能を操り,タンパク質の機能発現機構を解析できる革新的方法の確立を目指す.

Outline of Final Research Achievements

To understand complex cellular functions, it is important to systematically investigate the spatio-temporal functional expression of bioorganic molecules such as proteins and nucleic acids. However, there are few methods that allow analysis of endogenous bioorganic molecules in living cells, making it technically difficult. In this research, we established an innovative method to regulate RNA functions in mammalian cells and to analyze gene expression by using "a functional RNA and a small molecule" as a research tool.

Academic Significance and Societal Importance of the Research Achievements

本研究では生細胞内でRNA機能を操る新たな研究手法を創出し、未知の生命現象を解き明かす研究ツールとして利用することを目指した。研究期間内で大きな成果を得ることに成功し、国際的評価が最も高い核酸化学専門誌であるNucleic Acids Research誌(IF=19.160)への2報の報告を含む、4報への国際誌に研究成果を報告した。
