Outline of Research at the Start

本研究は、抗がん剤治療が血管内皮細胞 (EC)のpoly ADP-ribose polymerase (PARP)活性化を介して将来の血行性がん転移を促進させる機序を、マウスモデルや細胞実験、TCGA解析などを用いることで解明し、現在臨床で使用され始めているPARP阻害薬の血行性がん転移予防への適応拡大を目指すものである。

Outline of Final Research Achievements

In the present study, we investigated the mechanisms of chemotherapy-induced tumor metastasis via endothelial cell (EC)-derived poly ADP-ribose polymerase (PARP) activation to find possibilities that PARP inhibitors can be applied also as inhibitors against tumor metastasis during cancer therapies. We found that cisplatin (CDDP) induced PARP activation in ECs, CDDP pre-administration induced melanoma tumor cell metastasis and a PARP inhibitor, olaparib administration suppressed its effect in a mouse model.

Academic Significance and Societal Importance of the Research Achievements

本研究により、抗がん剤によるEC由来PARP活性化を介した血行性がん転移促進機序が解明されることにより、(1)すでに臨床で使用されているPARP阻害薬の血行性がん転移予防への適応拡大の可能性、(2)将来の血行性がん転移制御も考慮した効率的がん治療戦略の開発、に向けて一石を投じることが可能となる。
