In addition, cisplatin treatment induced long-term toxicities and the development of therapy resistance emphasize the need for novel therapeutics. In this study, we analyzed the effects of novel histone deacetylase (HDAC) and bromodomain and extraterminal domain-containing (BET) inhibitors to combine them into a potent HDAC-BET-fusion molecule and to understand their molecular mode-of-action. Treatment of (cisplatin-resistant) germ cell tumors (GCT), urothelial, renal, and prostate carcinoma cells with the HDAC, BET, and dual inhibitors decreased cell viability, induced apoptosis, and affected the cell cycle. Furthermore, a dual inhibitor considerably decreased tumor burden in GCT xenograft Molecular cancer therapeuticsEstablishment and Evaluation of Dual HDAC/BET Inhibitors as Therapeutic Options for Germ Cell Tumors and Other Urological Malignancies.PMC9630828GRK21582019-24#362016.041.1-3Nettersheim DAlves Avelar LASeiwert ABremmer FKurz TNiegisch GSkowron MAHofmann SAlbers PPetzsch PHoffmann MJTorres-Gomez HStephan AMuller MRBurmeister AFischer FKohrer KfalseEstablishment and Evaluation of Dual HDAC/BET Inhibitors as Therapeutic Options for Germ Cell Tumors and Other Urological Malignancies.Urological malignancies represent major challenges for clinicians, with annually rising incidences.
