Outline of Research at the Start

生細胞内で核酸の立体構造、安定性、相互作用などの情報を得るためにin-cell NMR法は有望な手法である。本研究では、細胞表面に細孔を形成する毒素蛋白質を用いて様々な構造モチーフを有する核酸を導入し、ヒト生細胞中の核酸のin-cell NMRスペクトルを測定する。これにより、in-cell NMR法を用いたヒト生細胞内核酸の安定性、相互作用の新たな評価方法を提案し、試験管内環境における性質と比較する。

Outline of Final Research Achievements

The intracellular environment is highly crowded with macromolecules and physicochemical properties inside the cells are different from those of in vitro. Therefore, it has long been thought that structures, dynamics, and interactions of nucleic acids can be different in in-cell and in vitro conditions. Here we evaluated the structural properties of nucleic acids in living human cells by in-cell NMR. In terms of intracellular structure, the direct evidence of the formation of parallel and antiparallel triplex structures were provided. Furthermore, base-pair opening dynamics of telomere G-quadruplex structure in living human cells was evaluated at base-pair resolution. We found that all G-G base-pairs open more frequently in living human cells than in vitro. We also detected the interaction of RNA aptamer to its target small molecule in living human cells. The potential of in-cell NMR for investigation of structural properties of nucleic acids in living human cells was demonstrated.

Academic Significance and Societal Importance of the Research Achievements

本研究では、in-cell NMR法により、ヒト生細胞内において核酸の構造、ダイナミクス、相互作用を解析する手法を確立し、その有用性を実証した。核酸が実際に機能を発揮する細胞内において核酸の構造情報を高い空間分解能で解析可能にする本技術は、核酸が関わる多くの基本的な生命現象の理解に貢献すると期待される。
