Outline of Research at the Start

子宮体癌は最近増加しており、好発年齢は閉経前後である。これまでの知見から、加齢により子宮内膜細胞は、幹細胞性が低下し細胞老化が誘導されるが、遺伝子変異が生じた細胞を細胞死誘導や細胞競合により排除する機能が低下すると、異常細胞が蓄積し子宮体癌の発生に繋がるのではないかと考えた。本研究では、子宮内膜の老化とがん化を分けるメカニズムを、細胞死誘導や細胞競合に及ぼす影響の観点から解明する。

Outline of Final Research Achievements

We have previously reported that IL-17RB is upregulated in the endometrium during aging. We established an IL-17RB-high expressing cell line and demonstrated that IL17B/IL17RB signaling expresses IL6, IL8, and IL1β through the NF-κB pathway. Using organoid formation in primary cultures of normal endometrium, we found that IL-6 and IL-8 increased the formation capacity, IL-1β decreased it, and only IL-1β increased the percentage of SAβgal-positive senescent cells. JNK pathway was extracted as the most relevant factor for IL17RB expression. IL-6 and IL-8 promoted cell proliferation and IL-1β induced cell senescence via JNK pathway. These results indicate that the types of cytokines secreted by senescent cells are involved in the mechanism that separates normal endometrium senescence from cancer development.

Academic Significance and Societal Importance of the Research Achievements

現在日本において晩婚化・晩産化による少子化が問題となっている。この原因として、加齢による卵や子宮内膜の老化による不妊症の増加が挙げられる。また、子宮体癌は罹患率が急増しているが、罹患率は閉経前後より増加してくる。このように加齢による子宮内膜の老化は不妊症や子宮体癌に関与すると考えられる。本研究により子宮内膜は老化により複数の炎症性サイトカインが分泌され、IL-1βは細胞老化、IL-6, IL-8は増殖に関与していることが明らかとなった。前者は着床不全、後者はがん化につながると考えられ、本研究の内容は学術的・社会的に意義がある。
