Outline of Final Research Achievements

Metabolic reprogramming of central carbon metabolism played important roles in the acquisition of anti-oxidative capacity in various types of cancer cells. In this study, we focused the metabolic interactions between cytoskeleton and glycolytic enzymes to acquire chemoresistance. We observed higher modification levels of glycolytic enzymes in paclitaxel-resistant cells than control cells. Furthermore, we compared metabolic characteristics between naive and Paclitaxel-resistant cells using mass-labelled glucose. Using metabolome analyses, we demonstrated metabolic features in Paclitaxel-resistant cells; activation of glycolysis, Serine synthetic pathway, and sulfur-containing amino acid metabolism. Our results illustrate that carbon derived from glucose is used for the production of antioxidants from sulfur-containing metabolites.

Academic Significance and Societal Importance of the Research Achievements

元来、抗がん剤に対する耐性獲得機構は遺伝子変異によって説明されているのが多いが、本研究では特定の酵素の翻訳後修飾レベルの変化によっても化学治療に対する感受性が変化することを見出した。また、微小管安定化剤によって解糖系が亢進し、分岐経路より耐酸化ストレス能が増すことから本研究をさらに発展させ、人為的介入により分岐経路を遮断することでストレス脆弱性を惹起できる可能性が示唆される。また、エネルギー代謝酵素の修飾レベルを調べることで有糸分裂阻害型抗がん剤の治療効果の奏効を予測するマーカーとなりうるのではないかと考えている。
