Outline of Final Research Achievements |
With the aim of elucidating the long-term effects of fetal changes in DNA chemical modification on health and physiological function after birth, we have developed an experimental system which enables us to manipulate gene function of Dnmt3a, a critical enzyme for regulating DNA chemical modification. Using mouse embryonic stem cells, we engineered Dnmt3a gene to generate a mutant allele which conditionally restores its function from deficient state to normal state. We validated its operation in embryonic stem cells.

Academic Significance and Societal Importance of the Research Achievements |
本課題で作製したDnmt3a遺伝子アリル(Dnmt3a-floxSTOP)は、胎生期におけるエピジェネティック状態変化の役割や長期的影響を明らかにするためのあらたなツールとなりうる。近年、胎生期・発達期といったライフステージの初期において経験する環境因子が、将来の健康と疾患のかかりやすさに影響を及ぼしうると考える学説が注目されている。本研究がそのしくみの基礎的理解に寄与することが期待される。
