Outline of Research at the Start

妊娠糖尿病(GDM)合併妊婦およびその出生児は共に将来的に2型糖尿病発症リスクが高い.母体において生活環境・遺伝要因,児では生活環境・遺伝要因に加えエピゲノム変化がその発症機序に関与すると推測されるが,日本人を対象とした網羅的検討はなされていない.本研究の目的は ,臨床遺伝リスクスコアを用いたGDM既往女性の産後糖代謝異常発症予測指標の作成および母体糖代謝異常における胎児エピゲノム変化の解析である.長期予後に着目した日本人GDMにおける遺伝因子・エピゲノム因子情報は,日本人GDM既往女性の産後管理指針の作成および出生児のDevelopmental Origin of Health and Disease仮説の解明に繋がるものと期待される.

Outline of Final Research Achievements

Neonates born to mothers with gestational diabetes mellitus (GDM) are at risk of metabolic syndrome in the future. Epigenetic modifications as well as environmental and genetic factors are thought to predispose offspring to develop metabolic disorders, however, data on Japanese subjects are not reported. Our genome-wide methylation analysis demonstrated that neonates in well-controlled GDM may not differ in DNA methylation compared with those born to mothers without GDM. Additionally, changes in DNA methylation might be associated with neonatal plasma glucose 1 hour after birth.

Academic Significance and Societal Importance of the Research Achievements

本検討により,血糖管理良好なGDM例の臍帯血DNAメチル化は健常例と同等であること,GDM母体からの新生児血糖値は胎児期のメチル化変化に関連することが示唆された.今後,同様のDNAメチル化解析データは児のエピゲノム変化に関する新たな情報となり,Developmental Origin of Health and Disease仮説の解明にも繋がるものと期待される.
