Outline of Final Research Achievements

Brain metastases show strong treatment resistance, and the current situation is that current anticancer drugs, molecular-targeted therapies, and radiation therapy do not provide fundamental efficacy. Therefore, it is essential to elucidate the treatment resistance rooted in the true nature of cancer and to develop a treatment method. According to our research results, the regulation of anaerobic glycolysis by the key molecule MPC (mitochondrial pyruvate transporter) of the Warburg effect induces epithelial-mesenchymal transformation (EMT) to make cancer stem cells, and multiple It was revealed that the treatment resistance to the anticancer drug was acquired. For cancer cells that are relatively prone to brain metastasis as a mechanism, the role of MPC in early brain metastasis is investigated by single cells from the three-dimensional reconstruction of the cell group that constitutes the blood-brain barrier (BBB) toward the future clinical application.

Academic Significance and Societal Importance of the Research Achievements

より精密な診断のためのバイオマーカーの探索や、新たな治療標的を提示することができるようになり、がん代謝を介したMPCと細胞の形質転換の関連性を通じて、創薬の標的化、機序の解明、抵抗性の予測を通じて、難治がんの精密医療に貢献することができた。手術切除試料を用いた動物モデル(PDX: patient derived xenograft)と、三次元組織構築を構成する細胞群の解析から、早期の転移浸潤における責任分子の役割を究明し、創薬の標的化、機序の解明、抵抗性の予測を通じて、難治がんの精密医療に貢献することができた。
