Outline of Final Research Achievements

The links between obesity in parents and their offspring and the role of genes and a shared environment are not completely understood. In this study, we examined whether the offspring from dams exposed to a high fat diet during pregnancy exhibited hypertension,insulin resistance and hyperlipidemia along with epigenetic changes in the expression of adipocytokine and other obesogenic and diabetogenic genes. Our data demonstrated that the exposure to an HFD in utero might cause a metabolic syndrome-like phenomenon through epigenetic modifications of other obesogenic and diabetogenic important gene as well as adipocytokine, adiponectin and leptin genes.

Academic Significance and Societal Importance of the Research Achievements

母体肥満・耐糖能異常下の子宮内環境による胎児プログラミングの変化がもたらす肥満・耐糖能関連遺伝素因への影響を示す最適なバイオマーカー候補として、アディポサイトカイン遺伝子や肥満・糖脂質代謝関連遺伝子のエピゲノム変化を同定した。生活習慣病発症を抑制し健やかな次世代育成に繋がる“先制医療”の実用化を目指すためヒトでの応用の端緒となる基盤研究結果と考える。
