Outline of Final Research Achievements

The efficiency of in vitro fertilization and early development was significantly lower in the MTH1/OGG1/MUTYH triple knockout (TOY-KO) mice compared with wild type. This is considered to be due to an increased spontaneous mutation frequency in the germ lineage cells of the TOY-KO parent mice. To search the mouse strain with milder mutator phenotype, we prepared MTH1/OGG1, OGG1/MUTYH and MTH1/MUTYH double knockout mice, and MTH1, OGG1 and MUTYH single knockout mice in addition to TOY-KO mouse. By germline mutation analysis using whole exome sequencing, MTH1/MUTYH double knockout mouse showed decreased (about 1/10) mutation frequency with different mutation spectrum from TOY-KO mouse.

Academic Significance and Societal Importance of the Research Achievements

2016年,我が国の全出生数に対する体外受精で生まれた子の割合は5.5%に達し,さらにその8割以上が凍結保存処置を経たものであった。これらの処置を経て生まれた体外受精児の約2%に何らかの異常の発生が報告されている。採卵,培養,凍結処置時に生じるゲノムへのダメージは一生涯,さらに子孫にまで引き継がれるものであり,その発生は極力抑制されなければならない。不妊治療に伴う次世代へのゲノムダメージの蓄積の実態解明を進め,その抑制方法を探すことは重要な課題である。
合わせて,ヒトの生殖・出産の適齢年齢は20歳~30歳であるという事実を広く知らしめ,不妊治療に頼らずにすむ社会環境構築の重要性を喚起したい。
