<p class="Abstract">Prostate cancer is major cause of cancer related deaths worldwide in men. There are new treatment methods and drugs are being developed with promising results in two of the prostate cancer cell lines (PPC-1 and TSU-Pr1). These two cells were treated with 20 uM of axitinib combined with dasatinib for 6-72 hours. The cell viability assessed by the cytotoxicity assay. Various regulatory genes such as c-KIT, cell cycle and apoptosis and angiogenic factors were also studied. The enzyme activity of apoptosis efector caspase-3 was colorimetrically determined. Axitinib and dasatinib combination lowered the survival rate of PPC-1 cells but enhanced the survival rate of TSU-Pr1 cells. The protein expression levels in apoptosis and angiogenesis factors were also found to be in contrast between the two cell lines. PPC-1 and TSU-Pr1 cells displayed a different response to axitinib with dasatinib, which explains different expression levels of regulators of cell-cycle, apoptosis and angiogenesis.</p><p> </p>

Abstract Background: Wilms’ tumor 1-associating protein (WTAP) plays an important role in cell physiological function and have attracted increased interest in cancer research recently. Cyclin-dependent protein kinases (CDKs) are known to participate in regulating the cell cycle and often connected to many malignancies in tumor. We aim to explore whether WTAP or CDKs could play an role in the initiation and progression of prostate cancer(PCa) and hope to provide new insights into PCa treatment and prognostic. Methods: Quantitative real-time PCR, western blotting and immunohistochemistry were performed to explore the expression of WTAP and CDK4 in prostate cancer tissues and cell lines. The survival analysis was used to investigate the association between WTAP expression and the clinical outcomes of prostate cancer. Prostate cancer cell lines were stably transfected with lentivirus approach. CCK-8 assay, colony formation assay, cell invasion and migration assay, cell cycle assay and tumorigenesis in nude mice were performed to study the effect of WTAP in prostate cancer cell lines. RNA immunoprecipitation assay, dual-luciferase reporter assay and siRNA transfection were performed to verify the direct binding sites of WTAP with CDK4 transcript.Results: In prostate cancer tissues and cell lines, WTAP was significantly up-regulated and high expression of WTAP was connected to poor clinical outcomes. Additionally, cell function test indicated that overexpression of WTAP in prostate cancer cell lines could promote cell proliferation, while knocking down showed an opposite results. Subcutaneous xenograft tumor model revealed that overexpression of WTAP could induce tumorigenesis in vivo. Mechanism study showed that CDK4 expression could regulate the expression level of WTAP. Moreover, WTAP could directly bind to 3’-UTR of CDK4 transcript and enhance its stability. Furthermore, specific inhibitors of CDK4 as well as small interfering RNA (siRNA) of CDK4 reversed the promotion of proliferation induced by WTAP.Conclusions: These data indicated that WTAP may act as an oncogenic in prostate cancer by directly binding to CDK4 3’-UTR and stabilizing its transcript which might provide new insights into prostate cancer treatment and prognostic.

Prostate cancer patients whose tumors develop resistance to conventional treatment often turn to natural, plant-derived products, one of which is sulforaphane (SFN). This study was designed to determine whether anti-tumor properties of SFN, identified in other tumor entities, are also evident in cultivated DU145 and PC3 prostate cancer cells. The cells were incubated with SFN (1–20 µM) and tumor cell growth and proliferative activity were evaluated. Having found a considerable anti-growth, anti-proliferative, and anti-clonogenic influence of SFN on both prostate cancer cell lines, further investigation into possible mechanisms of action were performed by evaluating the cell cycle phases and cell-cycle-regulating proteins. SFN induced a cell cycle arrest at the S- and G2/M-phase in both DU145 and PC3 cells. Elevation of histone H3 and H4 acetylation was also evident in both cell lines following SFN exposure. However, alterations occurring in the Cdk-cyclin axis, modification of the p19 and p27 proteins and changes in CD44v4, v5, and v7 expression because of SFN exposure differed in the two cell lines. SFN, therefore, does exert anti-tumor properties on these two prostate cancer cell lines by histone acetylation and altering the intracellular signaling cascade, but not through the same molecular mechanisms.
