Outline of Final Research Achievements

Using our new endometrial cancer mouse models, we found that the Pten in uterine stroma represses malignant transformation of Pten null uterine epithelium. We further demonstrated that Pten in uterine epithelium is essential to repress uterine stromal sarcoma in mouse model. We also found some aggravating factors for endometrial cancer initiation and progression in this study.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた子宮がん発生への周辺組織の影響および卵巣ホルモンの子宮がん発生・進行への関与はこれまでの常識を覆す結果を含んでおり、学術的意義がある。また、本研究で新たに発見された子宮体癌発生・進行を促進する憎悪因子は、子宮体癌の新たな治療ターゲットとなり、新規治療薬の開発につながると考えられ、社会的意義がある。
