| Research Abstract |
1) We conducted a multi-institutional retrospective outcome-study on the patients with invasive bladder cancer who underwent radical cystectomy. This outcome study enrolling more than 1000 patients showed the clinical significance of the patient's selection in terms of chemo-sensitivity, and also indicated that the response of primary tumor to the chemotherapy might be a useful surrogate endpoint for the prediction of the survival benefit of the patients. In order to overcome drug-resistance of cancer cells, we focused attention on NQO1, an enzyme with ROS activity and specifically over-expressed in bladder cancer cells. In this analysis suggested that dicoumarol, an inhibitor against NQO1, could enhance cytotoxicity of CDDP in urogenital cancer cells with wild-type p53 through the p53/p21/JNK pathway.
2) By using cDNA microarray analysis on RCC specimens, we revealed more than 10 genes associated with clinical outcome of RCC, and the functional analysis on these genes are now ongoing. In addition, we have just started a multi-institutional outcome study enrolling more than 1000 RCC patients.
3) By using tissue-microarray analysis, we investigated the association between the expression pattern of prostate cancer related proteins and the clinical outcome. In addition, we established a novel androgen-dependent prostate cancer xenograft, and showed the molecular mechanism of hormone-independency associated with AR mutations.
