Outline of Final Research Achievements

We examined the associations of obesity tendency at 12 years of age with prenatal exposure to Perfluoroalkyl substances (PFASs) and genome-wide DNA methylation changes in cord blood. Of the 8 PFASs analyzed, perfluorooctanoic acid (PFOA) were inversely associated with obesity tendency (per log10-unit: odds ratio (R)=0.23, 95% confidence intervals (95% CI), 0.06 to 0.89). While, in adjusted robust linear regression models, there was no CpG with significant epigenome-wide methylation alteration (FDR q-value < 0.05). In a previous study, we found a PFOA associated-down methylation region on the GFPT2 gene, which is suggested to be associated with adiposity in childhood. However, no significant association between methylation levels at CpG sites on t the GFPT2 gene and obesity tendency was found.
We are currently conducting exposure measurements to investigate in detail the association with DNA methylation changes, childhood obesity, and prenatal PFASs exposure.

Academic Significance and Societal Importance of the Research Achievements

母体の環境要因によるエピゲノム変化が次世代の健康リスクの上昇・低下に関与するため、エピゲノムを介したメカニズムを解明することは環境化学物質のリスク評価および疾病予防にとって重要である。
本研究は、難燃剤などで多用される有機フッ素系化学物質の胎児期曝露に起因する臍帯血DNAのメチル化変化を介して、曝露が児の発育・成長に与える影響を出生前向きコホート研究により明らかにすることを目的とする。エピゲノムを介した胎児期環境による健康影響を引き起こすメカニズムが解明されれば、次世代の健康リスクの軽減や影響を減らすことに大きく貢献できる。
