Outline of Research at the Start

網羅的なエピゲノム解析を行って、アレルギーのエピジェネティックな制御のメカニズムを解明する。

Outline of Final Research Achievements

We tested the possibility that allergic predisposition induced in the parents could be inherited by the offspring using a mouse model of OVA allergy and found that pups from allergen-sensitised mice were significantly more sensitised and allergic than pups from normal male and female crosses. This result was obtained with high reproducibility. Therefore, sperm were collected from allergen-induced and normal males, respectively, and analysed comprehensively by RNAseq. The results showed that non-coding RNA (ncRNA) contributed significantly to these phenomena.

Academic Significance and Societal Importance of the Research Achievements

アレルギー素因の遺伝に関する報告は、世界的にもまだ存在しない。また、生殖細胞のmicroRNA発現の変化が次世代の生理・免疫・記憶・形態にどの様に影響を与えるかの分子機構に関しては世界中の研究者が鎬を削って研究を進めているが明確な「解」は得られていない。それゆえに、本研究の成果は、分子遺伝学に全く新たな知見を与えるであろう。そしてアレルギー疾患に留まらず癌・精神的疾患・糖代謝異常など多くの疾患の予防・治療戦略に大きく影響を与える成果をあげるであろう。
