Outline of Final Research Achievements

Cancer stem cells are promising therapeutic targets for cancer therapy. In this regard, identifying specific genes for cancer stem cells can be a key for therapy development. Through proteomic analyses, we identified S100A10 expression enhanced in cancer stem cells and many malignant tumors. We examined the properties of S100A10 and revealed their roles in cancer cells. First, S100A10 contributes to cancer cell migration and invasion. Second, it supports tumor formation in vivo. Third, S100A10 is not necessary for stem cell-related transcription factors. Fouth, S100A10 supports cytoskeleton organization. Taken together, S100A10 is a valid therapeutic target for cancers.

Academic Significance and Societal Importance of the Research Achievements

悪性度の高い癌の多くはドライバー遺伝子が発見されず、免疫チェックポイント阻害薬が無効な症例も多いことから新たな創薬が求められている。本研究の成果は、悪性度の高い癌に対するS100A10標的治療が有効である可能性を示しており、今後の創薬に繋がる可能性がある。学術的な特徴は、S100A10が細胞骨格制御を担う重要分子であることを明らかにした点にある。S100蛋白質は約20種存在することから、これらの分子ネットワークが支える細胞生物学的役割の解明に繋がる可能性が出てきた。このような点から本研究の学術的意義は高いと考えられる。
