Ceramide and dihydroceramide are proliferation and death associated sphingolipids. Recent cancer research are focused on clarifying cancer-sphingolipid metabolism. In last years, ceramide as a key molecule in sphingolipid metabolism relationship has been investigated for its anticancer activity via augmenting its intracellular level by ceramidase inhibitor application. Prostate cancer is amoung the most frequent human cancers and is reported as second most common cancer-related death cause. Prostate cancer is common at ages older than 65. The aim of this study was to investigate the potential cytotoxic activity of a ceramidease inhibitor (1S,2R)-D-erythro-2-(N-Myristoylamino)-1-phenyl-1-propanol (D-erythro-MAPP) on human prostate cancer DU-145 cells by using MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay, flow cytometry, confocal and TEM microscopy. MTT findings showed that D-erythro-MAPP caused toxicity in low doses on DU-145 cells. Confocal and TEM microscopy findings indicated hole formation in cytoskeleton, chromatin condensation, horseshoe-shaped cell nuclei as morphological changes and blebbings on cell membrane, fragmentation of nuclei, chromatin condensation and loss of criastae of as ultrastructural changes, respectively. Flow cytometry findings showed that D-erythro-MAPP triggered apoptosis in short term application of 24 hours on DU-145 cells. According to results it can be conculded that D-erythro-MAPP decreased viability of DU-145 cells in dose-dependent manner.  Our findings stated the anti-cancer and cytotoxic potential of D-erythro-MAPP on DU-145 and this agent might be used in drug developing for cancer treatment after the further in vitro and in vivo studies. </span> </span> <br /> </p>}, publisher={Bilecik Seyh Edebali University}
