Keywordsエネルギー分配 / DNMT3 / ミジンコ / DNAメチル化
Outline of Research at the Start

本研究では、淡水の主要な1次消費者であるミジンコをモデルとして、動物個体に流入するエネルギーの分配を決定する分子メカニズムを解明する。代表者らは最近、ミジンコにおいてde novo DNAメチル化酵素3.1(DNMT3.1)が飢餓時に稀少な細胞で発現し、エネルギー分配のマスター調節因子として働くことを発見した。そこで、本研究ではDNMT3.1発現細胞をエネルギー分配の中枢細胞と定義し、本細胞でDNMT3.1に制御される遺伝子ネットワークを解明する。

Outline of Final Research Achievements

To understand mechanisms underlying energy allocation in organisms, we used the freshwater zooplankton Daphnia magna which has been used as a model for studying environmental responses. First, we attempted to introduce a reporter gene into the DNMT3.1 gene that controls energy allocation under starved conditions in Daphnia magna. Unexpectedly, attempts to introduce a reporter gene into the DNMT3.1 gene resulted in embryonic lethality. We established a novel DNMT3.1 null mutant and identified another gene responsible for energy allocation. These results contribute to understanding the molecular basis of energy allocation.

Academic Significance and Societal Importance of the Research Achievements

生物において、限られたエネルギーをいかに身体の維持、成長、繁殖などの各生物活動に配分するかは、個体群動態、個体における進化や適応、そして老化や疾患等の理解まで生命システムの幅広い階層における現象を理解する上で根源的な問題であるが、そのメカニズムはほとんど解明されていない。こうした中でミジンコにおけるエネルギー分配のメカニズムの基盤を遺伝子レベルで明らかにした本研究は、個体・個体群レベルでの進化や適応の原理のみならずエネルギー分配機構の生物間の共通性や多様性の理解に貢献できる。
