Outline of Final Research Achievements

It has been previously reported that in cancer cells, glucose metabolism is biased toward anaerobic metabolism. Our research so far has focused on amino acid metabolism. We examined the residual cancer cells during surgery. We succeeded in detecting cancer cells left in the tissue.
We also clarified the metabolism of cancer cells and clarified that the sensitivity of anticancer drugs is changed by blocking some pathways of amino acid metabolism.

Academic Significance and Societal Importance of the Research Achievements

がん細胞特有のアミノ酸代謝を複数経路見出すことができた。また、その経路を遮断することにより抗がん剤への感受性が変化した。がん治療の中で化学療法を行う際には特殊な条件を設定することにより抗がん剤の効果を増大させたり、副作用低減させたり可能性が示唆された。
