Outline of Research at the Start

小学6年時の肥満傾向と関連している臍帯血DNAメチル化変化をエピゲノム網羅的解析により同定し、そのメチル化変化から肥満と結びつく胎児期および生後の環境要因を出生コホート研究により実証する。また、遺伝要因も複合的に健康リスク発現に関与していると考えられるため、遺伝子多型による感受性を考慮したハイリスク群を明らかにし、学童期以降の肥満の原因を環境要因と分子機序の両面から明らかにし予防医学に貢献する

Outline of Final Research Achievements

The aim of this study was to identify epigenomic changes involved in fetal environment and postnatal disease and health status. In a case-sub-cohort study including 218 obesity and 282 non-obesity children, we analyzed epigenome wide association study analysis (EPIC) in cord blood DNA. In robust linear regression, methylation rate of only 1 CpG site was significantly differenced with/without maternal pre-pregnancy obesity (FDR q < 0.05). Among only mothers having male offspring, methylation rate of 2 CpG sites were differenced with/without maternal pre-pregnancy obesity (FDR q < 0.1). In KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis, functional pathways of nutrient metabolism, inflammation and immune system were detected as linking to maternal pre-pregnancy's obesity.

Academic Significance and Societal Importance of the Research Achievements

胎児期の環境と出生後の健康リスクを結ぶエピゲノム変化に関する疫学的エビデンスはまだ不十分である。前向き出生コホート研究により、エピゲノムを介する胎児期曝露の健康リスク発現メカニズムを解明できれば、世界的に先駆的な実証的エビデンスとなる。成長後の健康リスク、特に発症前の予測・診断が可能になれば予防的な早期介入により次世代の健康リスク軽減に貢献できると考える。これらにより、最終的には世界に先駆けて「エピゲノムに基づく次世代の疾病予防」の礎を確立することができる。
