Outline of Research at the Start

本計画研究では、様々な環境要因で変動する核酸構造に依存した遺伝子の発現調節(多元応答)に着目し、生命システムに維持されている「多元応答」の分子機構を解明する。そのために、
1. 生物種がさらされ得る環境変動に対する「多元応答」の網羅的解析
2. バイオインフォマティクス解析による「多元応答」を誘起する核酸構造の抽出
3. 生物種間に存在する「多元応答」機構の共通点、相違点の解析
の研究課題を進める。

Outline of Final Research Achievements

This research project aimed to analyze nucleic acid structures involved in "Dimensional Response", which modulates gene expressions depending on various environmental factors. To demonstrate such nucleic acid structures maintained in living systems, this project performed genome wide and transcriptome wide analyses with biochemical and bioinformatic technologies. For the guanine quadruple (G4) structure, we extracted the G4-forming potential regions from the genomes of approximately 6,000 species and registered them in a newly constructed G4 database. In addition, we experimentally demonstrated that G4 structures can be formed in regions more than previously expected on the genome under molecular crowding environments. Experimental analyses also demonstrated that RNAs forming unique structures bind to specific proteins and can be involved in the regulation of protein functions and epigenetic chemical modifications of nucleic acids.

Academic Significance and Societal Importance of the Research Achievements

様々な生物種のゲノムを網羅的に解析し、遺伝子の発現調節に関与し得る核酸構造をデータベースとして蓄積した。G4構造については、既にデータベースの公開準備が整っている。さらに、分子環境に応答して特定の核酸構造を形成できる領域、タンパク質の機能調節に関与する核酸構造などをゲノムワイド、トランスクリプトームワイドに解析して明らかにした。本研究のように、生物種の分類枠組みを超えて核酸構造による遺伝子の発現調節機構の共通点や相違点を明らかにしていく試みはほとんどなく、得られる成果の学術的意義は大きい。また、核酸構造を変化させて遺伝子発現を制御する技術の開発といった社会的意義の高い研究への展開も期待される。
