Outline of Final Research Achievements

Integrated Stress Response (ISR), a typical metabolic stress response pathway, functions as a defense mechanism in cancer cells. In this study, we focused on the oncogenic signal-mediated regulation mechanisms of the ISR and their roles in tumor growth. As a result, we succeeded in identifying the factors involved in the ISR regulation downstream of oncogenic signals. We further promoted research for a novel therapeutic strategy that can induce synthetic lethality by disrupting the ISR regulation mechanisms.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的特色は、がん細胞の代謝ストレス応答のなかで、がん化シグナルによって制御されるメカニズムを明らかにし、がん特異的にストレス応答を破綻させる方法を開発しようという点にある。基盤的な情報を蓄積することに加え、既に臨床で使用されているがん化シグナル阻害剤を用いた実証的な検討も行った。速やかな臨床応用の可能性も期待される本研究の成果は、新たながん治療法の開発という社会的要請に応えるものと位置づけられる。
