Outline of Final Research Achievements

Peritoneal dissemination is the most common form of metastasis in gastrointestinal cancer, and is associated with an extremely poor prognosis. We developed a new approach to visualize floating tumor cells using a green fluorescent protein (GFP)-expressing attenuated adenovirus in which the telomerase promoter regulates viral replication (TelomeScan, OBP-401). Moreover, we used a unique TelomeScan derivative (TelomeScan-F45, OBP-1101) that have a strict replication control function by micro-RNA together with targeting properties through CD46; however, unfortunately, the combination strategy was not able to show the usefulness.

Academic Significance and Societal Importance of the Research Achievements

テロメラーゼ特異的蛍光標識ウイルス製剤TelomeScan(OBP-401)では、EpCAMなど上皮系マーカーを指標としたCellSearchシステムでは検出不能であった、より悪性化して上皮間葉転換(EMT)を生じたがん細胞も標識することができ、鋭敏で高精度な検出感度が確認できた。TelomeScan-F45(OBP-1101)を併用するデュアル体外診断システムの確立は困難であったが、TelomeScanによる臨床的に有用なプラットフォームは構築できたと考える。
