    Abstract:
    BACKGROUND: The aim of our study was to explore the anti-tumoral potential of the Nitric Oxide-Donating Non-Steroidal Anti-Inflammatory Drugs (NO-NSAID) NCX1102 (nitrosulindac), on three human prostatic epithelial cell lines at varying degree of transformation (PNT1A, LNCaP, and PC3). METHODS: Cytotoxicity, anti-proliferative effects, cell-cycle alterations, morphological changes, and apoptosis were investigated after treatment with nitrosulindac in comparison to the native molecule sulindac. Involvement of the polyamine pathway in the action of nitrosulindac was also examined. RESULTS: Nitrosulindac but not sulindac exerted a cytotoxic effect on all cell lines and an anti-proliferative effect on LNCaP and PC3 cells only. Nitrosulindac differentially altered the cell cycle, induced mitotic arrest and displayed a pro-apoptotic activity in all cell lines. Finally, the polyamine pathway does not seem to be involved in the mechanism of nitrosulindac action. CONCLUSIONS: Our results demonstrate the anti-proliferative and proapoptotic activity of nitrosulindac on prostate cancer cell lines and suggest its potential interest for new strategies in the management of prostate cancer.
