학위논문(박사)--서울대학교 대학원 :의과대학 의학과,2020. 2. 이은식.Introduction: We investigated the antitumor effects and the possible molecular mechanisms of MutT homolog 1 (MTH1) inhibitors, TH588 or TH287, in cisplatin-sensitive (T24) and -resistant (T24R2) human bladder cancer cell lines. Methods: Cell Counting Kit-8 (CCK-8) and clonogenic assays were performed to assess the anti-proliferative effect of TH588 or TH287 on T24 and T24R2 cells. The generation of reactive oxygen species (ROS) in T24 and T24R2 cells was evaluated with 2,7-dichlorofluorescein diacetate using the IncuCyte® ZOOM System. Flow cytometry was performed to analyze the changes in cell cycle and apoptosis. The expression of proteins related to apoptosis and cell cycle was determined by w...
