Outline of Final Research Achievements

The aim of this study was to characterize the intracellular dynamics of metabolites in molecular subtypes of urothelial carcinoma by metabolomics analysis and to identify biomarkers and therapeutic target molecules that predict response and resistance of treatments from a metabolomics perspective.The results revealed that the two metabolites (isopropylmalic acid and gluconic acid) can be classified into three subtypes: Luminal, p53-like, and Basal/squamous. In particular, a common increase in gluconic acid was observed in cisplatin-resistant cell lines.

Academic Significance and Societal Importance of the Research Achievements

今まで進行性または転移性尿路上皮癌に対して白金製剤を中心とする画一的な治療が行われてきた。最近、免疫チェックポイント阻害剤や分子標的治療の新たな治療薬に関するエビデンスが報告されたが、個別化治療のためのバイオマーカーはない。本研究では、分子サブタイプまたはシスプラチン耐性とメタボロームの関連を示したことで、従来網羅的遺伝子発現解析が必要であったサブタイプ分類を簡便に行うことを可能にし、シスプラチン耐性のバイオマーカーや治療標的分子の探索に使用できる可能性がある。
