| Outline of Final Research Achievements |
Tumor cells often undergo cellular senescence when treated with DNA-damaging agent or radio-therapy (TIS: therapy-induced senescence) in addition to cell death. TIS cells are thought to survive longer time, and promotes relapse and/or emergence of therapy-resistant tumors by various mechanisms. In this study, we tried to understand metabolic reprograming during TIS, and to explore it as new therapeutic target in order to improve adjuvant therapy of mammary tumors.

| Academic Significance and Societal Importance of the Research Achievements |
近年、補助療法として各種分子標的治療の発展は目覚ましいが、それらの恩恵を受けられるのは一部患者に限られる。よって、従来型の化学療法・放射線療法は今後も引き続き重要で、より一層の治療効果向上や副作用改善が求められている。とくに前者に関し、治療抵抗性の解明が大きなブレークスルーになると期待されている。本研究にて、TISに伴う代謝変化や関連表現型、およびそれらの分子メカニズムの一部を明らかにすることが出来た。新たな乳がん補助療法の開発への応用が期待される。
