Outline of Final Research Achievements

A novel gene expression system that dramatically increases promoter activity while maintaining cancer specificity can be used as a new technology to strongly label and detect very few free cancer cells. The optimum conditions were also examined, and data for practical use of in vitro diagnostic methods were obtained. In addition, its usefulness has been confirmed as a technique for collecting detected free cancer cells and establishing them as cell lines.

Academic Significance and Societal Importance of the Research Achievements

当該システムを用いることで、血液や尿中に遊離したごくわずかな生きた癌細胞を発光・ラベルさせることが可能となる。今後、臨床の現場において、幅広い癌種について癌転移等の可能性を早期に予測できる診断法につながることが期待される。また、当該システムを応用することにより、生きたまま遊離癌細胞を採取してセルラインとして樹立することが可能となる。遊離癌細胞と原発巣の癌細胞等とを比較して新規転移関連マーカーの探索を行うことや、患者の予後診断、治療に利用できる可能性がある。
