Outline of Final Research Achievements

Tumor microenvironment plays an important role in cancer growth and metastasis. The applicant has so far found and reported that cancer cells remaining under nutrient deprivation under hypoxia promote malignant transformation and resistance to cancer treatments. This study elucidated the mechanism of malignant transformation of cancer induced by hypoxia and nutrient starvation from detailed analysis of cancer stem cells, and a novel cancer control method targeting cancer stem cells resistant to hypoxia and nutrient starvation. Research was aimed to development of novel anti-cancer strategy, we elucidated malignant transformation mechanisms caused by tumor microenvironments such as hypoxia, nutrient starvation and acidic pH, and a new target that can be expected to have a synergistic effect in combination with existing chemotherapy and angiogenesis inhibition therapy for molecular basis of and therapeutic application.

Academic Significance and Societal Importance of the Research Achievements

本研究の低酸素・低栄養の培養系を用いて樹立した細胞株を利用することにより、低酸素・低栄養の腫瘍微小環境における癌悪性化と治療抵抗性のメカニズムを解明し既存の抗癌剤や血管新生阻害剤と併用可能な新しい制癌法を開発することが可能になる。これら抵抗性の克服は、次世代の抗癌剤や血管新生阻害剤の開発にきわめて重要と考えられ、本研究は、
(1)大腸がん、乳がん、肝がんなどの血管新生阻害療法が承認されている癌治療についてさらに改良を加えること
(2)Hypovascularな膵臓癌や、高転移性な脳腫瘍などの抗癌剤や血管新生阻害療法の効果が見られない難治癌のモデル系として非常に有用で意義のある研究と考えられる。
