Outline of Final Research Achievements

This study aimed to observe the in vivo combined effects of candidate drugs targeting "cancer metabolism" on neuroblastoma for clinical application. We performed expression and metabolite analyses on tumor mouse models by removing the tumors after administration of the candidate drugs. Expression analysis revealed the mechanism of the drug and observed compensatory changes in tumor cells in response to the drug. Meanwhile, metabolite analysis revealed different metabolic profiles in different tumor cell lines, suggesting that the metabolic kinetics of the cells result in different drug effects. We will continue our research to integrate these results to identify candidate concomitant drugs and treatment optimization.

Academic Significance and Societal Importance of the Research Achievements

神経芽腫は小児の悪性固形腫瘍のうち脳腫瘍についで多く、うち半数程度を占める高リスク例の予後は未だに不良である。また、抗がん剤の大量投与による急性期および晩期の合併症も大きな問題である。このため、効果が高く副作用の少ない新規治療戦略が強く求められる。本研究が着目した「がん代謝」の性質は腫瘍細胞に特異的であり、これを標的とした治療は正常細胞への障害が抑えられることが期待できるほか、従来の化学療法とは異なる機序であることから治療効果の上乗せが期待できる。本研究の2つのモダリティによる成果を複合することで、がん代謝を標的とする治療の臨床応用に向けた最適化に役立つことが期待される。
