Outline of Final Research Achievements

In the present study, we investigated the significance of REV7 in spermatogenesis. In consequence, we demonstrated a possibility that REV7 plays an important role in self-renewal of the spermatogonial stem cells. Induced deletion of REV7 in adult mice caused alterations of expression of genes involved in spermatogenesis in the testis. We identified various proteins interacting with REV7 using germ cell tumor cell lines, and we also found several candidates of transcription factors that control REV7 expression. In addition, using biopsy specimens of the testes in patients with male infertility, we immunohistochemically revealed that REV7 expression in the germ cells in seminiferous tubes was associated with severity of impairment in sperm maturation. These results indicate that REV7 is essential in adult spermatogenesis, and it is necessary to elucidate the functional mechanism of REV7 in spermatogenesis.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、生殖細胞維持・精子形成においてREV7が必須の蛋白であることが初めて明らかになったことから、精子形成過程をコントロールする新たな分子メカニズムを提唱することができる。それにより、生殖細胞研究に今までと異なった新しい視点を提案することができ、今後の生殖細胞研究の進展が期待できる。また、REV7の欠損が引き起こす病態を詳しく解析することにより、遺伝子発現異常による男性不妊症の発症機序の一端を解明できる可能性があり、将来的に精子形成不全、無精子症などの男性不妊症の原因解明、治療の開発に貢献することができる可能性がある。
