Outline of Research at the Start

子宮体がんではPTEN不活性を高頻度に認め、発がんにおけるその重要性は多数の研究で立証されているが、他の高頻度な遺伝子異常の子宮内膜発がんとの関連については未だ不明な点が多い。申請者はマウス正常上皮オルガノイド(OR)を用いた「ex vivo発がんモデル」を消化系がんを中心に確立し、子宮内膜ORにおいても複数の遺伝子異常の再現により悪性化に成功している。そこで本研究では、このex vivoアプローチをさらに発展させ、ホルモンの影響も統合した包括的な子宮体がんモデルを確立するとともに、樹立済みの高転移性腺癌ORの解析を通して子宮内膜の発がんおよび転移促進的な新たな遺伝学的相互作用を明らかにする。

Outline of Final Research Achievements

We reconstituted genetic aberrations in endometrial organoids (EmOR) from various genetically engineered mice by lentivirally introducing cDNA and shRNA, and examined their tumorigenicity by inoculation into dorsal skin of nude mice. We found that EmOR carrying mutant Kras and Cdkn2a knockdown or Trp53 loss developed carcinosarcoma. Unlike an earlier in vivo study, EmOR with mutant Kras and concomitant Pten knockdown never developed tumor, whereas late-passage EmOR exclusively gave rise to adenocarcinoma with lymph node metastasis. Through the analyses of the resultant tumor, we found that Tgfbr2 loss may be critically implicated in endometrial carcinogenesis. The validation experiments revealed that KrasG12D-expressing early-passage EmOR with Tgfbr2 loss indeed developed carcinoma, whereas additional knockdown of Cdkn2a or Pten almost invariably induced metastasis. Thus, we gained novel insights into the carcinogenesis and metastasis of endometrial cancer using organoid models.

Academic Significance and Societal Importance of the Research Achievements

子宮体がんの発がんおよび転移機構を解明するために、一般的に利用される遺伝子改変マウスの作製とは異なる方法で発がんモデルの確立を試みた。具体的には、オルガノイド培養法でマウス正常子宮内膜細胞を培養し、遺伝子異常の導入後に免疫不全マウスに移植、腫瘍原性の有無を評価した。ヒト子宮体がんで高頻度の遺伝子異常やシグナル経路の異常をマウス子宮内膜オルガノイドに再現することで発がんだけでなく転移性腫瘍の誘導に成功した。本アプローチを利用することで、子宮体がんで同定された意義不明な遺伝子異常の発がんに与える影響の検証も可能となり、子宮体がんの本態解明や治療標的探索など様々な研究を促進することが期待される。
