Project description:Identification of bladder cancer subsets 142 primary bladder tumors including superficial and invasive tumors were arrayed. 73 invasive tumors out of 142 tumors were used for muscle invasive baldder cancer classification
Project description:We aimed to provide a molecular description of Lynch syndrome-associated urothelial cancer in relation to molecular subtypes of sporadic bladder cancer. Whole genome mRNA expression profiles of 41 tumors and immunohistochemical stainings against FGFR3, KRT5, CCNB1, RB1, and CDKN2A (p16) of 37 tumors from Lynch syndrome patients were generated. Pathological data, microsatellite instability, anatomic location, and overall survival data was analyzed and compared with data from sporadic bladder cancer.
Project description:Purpose: The goals of this study are to compare 1. The transcription profile in KDM6A wildtype and KDM6A mutated urothelial bladder carcinoma. 2. The transcriptional changes in KDM6A mutated urothelial bladder carcinoma upon EZH2 inhibitor treatment.
Project description:Bladder cancer is a major and mortal disease in urological area. Cisplatin is a key drug for bladder cancer especially for muscle invasive cases. In most cases of bladder cancer, cisplatin is effective; however, resistance to cisplatin is critical for patient’s prognosis. Thus, treatment strategy for cisplatin resistant bladder cancer is essential to improve current prognosis. In this study, we established cisplatin resistant bladder cancer line (CR cells) using a urothelial carcinoma line UM-UC-3 cells. We screened potential targets for CR cells and found that claspin is overexpressed in CR cells. Claspin mRNA knockdown revealed that claspin has a role in cisplatin resistance in CR cells. In our previous study, we found HLA-A*02:01-restricted CLSPN peptide by an HLA ligandome analysis. We thus generated CLSPN peptide specific CTL clone and found that CLSPN peptide-specific CTL clone recognized CR cells at higher levels compared with that of UM-UC-3 wild type cells. These findings indicate that claspin is a driver for cisplatin resistance and claspin peptide-specific immunotherapy is effective for cisplatin resistant cases.
Project description:Comprehensive evaluation of human cell lines for the transcription dynamics in response to the inhibition of PKC isozymes ε & ζ in bladder cancer.
Project description:Newcastle disease virus (NDV) is an avian virus that selectively replicates and kills many different types of cancer cells and is being developed for cancer treatment. Our aim was to establish persistent infection in EJ28 and TCCSUP bladder cancer cells and identify the dysregulated genes and disrupted molecular pathways associated with persistent infection.
