title: [Epigenetics in urothelial cancer: Pathogenesis, improving diagnostics and developing novel treatment options].
abstract: Urothelial carcinoma of the bladder is a common tumor for which improvements in diagnostic markers and new therapy approaches, in addition to or combined with standard chemotherapy, are urgently required. Epigenetic alterations could provide both novel diagnostic markers and therapeutic targets as they are emerging as crucial factors in the development and progression of this tumor type, likely contributing to altered differentiation and metastatic potential. These alterations affect DNA methylation, histone modifications, chromatin remodeling, long noncoding RNAs, and microRNAs. Factors involved in histone modifications and chromatin remodeling appear to be particularly frequently inactivated by mutations. Thus, histone-modifying enzymes may represent good targets for rational new therapeutic approaches, although thorough investigation of their complex functions is a prerequisite. DNA methylation changes and altered miRNA expression provide promising biomarkers for diagnosis and prognosis that need further validation in comprehensive and well-standardized studies.
