Resveratrol (RES) is the most effective natural products used for the treatment of a variety of cancers. In this study, we tested the effect of RES in enhancing the efficacy of docetaxel (DTX) treatment in prostate cancer (PCa) cells. The C4-2B and DU-145 cell lines were treated with RES, DTX and combination followed by evaluating the apoptosis and cell cycle progression. The combined drug treatment up-regulates the pro-apoptotic genes (BAX, BID, and BAK), cleaved PARP and down regulates the anti-apoptotic genes (MCL-1, BCL-2, BCL-XL) promoting apoptosis...

Connexins (Cxs), the subunits of gap junction channels, are involved in many physiological processes. Aberrant control of Cxs and gap junction intercellular communication may contribute to many diseases, including the promotion of cancer. Cd exposure is associated with increased risk of human prostate cancer and benign prostatic hyperplasia. The roles of Cxs in the effects of Cd on the prostate have, however, not been reported previously. In this study, the human prostate epithelial cell line RWPE-1 was exposed to Cd...

Pyrroline-5-carboxylate reductase 1 (PYCR1) is an enzyme involved in cell metabolism, which has been shown to be up-regulated in cancers. However, the functions of PYCR1 in prostate cancers (PCa) are still largely unknown. In the present study, we found that PYCR1 was highly expressed in prostate cancer tissues and then knocked down PYCR1 in PCa cell lines (DU145, PC-3 and LNCap) via lentivirus-mediated gene delivery and analyzed its biological function. Both qRT-PCR and western blotting indicated that PYCR1 was suppressed efficiently after sh-PYCR1 infection...

Nuclear factor-kappa B1 (NF-κB1) is a pleiotropic transcription factor and key contributor to tumorigenesis in many types of cancer. Numerous studies have addressed the association of a functional insertion (I)/deletion (D) polymorphism (-94ins/delATTG, rs28362491) in the promoter region of NFKB1 gene with the risk of various types of cancer; however, their conclusions have been inconsistent. We therefore conducted a meta-analysis to reevaluate this association. PubMed, EMBASE, China National Knowledge infrastructure (CNKI), and WANFANG databases were searched through July 2016 to retrieve relevant studies...

Malignant tumors display remarkable heterogeneity to the extent that even at the same tissue site different types of cells with varying genetic background may be found. In contrast, a relatively consistent marker the scavenger receptor type B1 (SR-B1) has been found to be consistently overexpressed by most tumor cells. Scavenger Receptor Class B Type I (SR-BI) is a high density lipoprotein (HDL) receptor that facilitates the uptake of cholesterol esters from circulating lipoproteins. Additional findings suggest a critical role for SR-BI in cholesterol metabolism, signaling, motility, and proliferation of cancer cells and thus a potential major impact in carcinogenesis and metastasis...

Epigenetic silencing of tumor suppressor genes is a phenomenon frequently observed in multiple cancers. Ras-association domain family 1 isoform A (RASSF1A) is a well-characterized tumor suppressor that belongs to the Ras-association domain family. Several studies have demonstrated that hypermethylation of the RASSF1A promoter is frequently observed in lung, prostate, and breast cancers. Phenethyl isothiocyanate (PEITC), a phytochemical abundant in cruciferous vegetables, possesses chemopreventive activities; however, its potential involvement in epigenetic mechanisms remains elusive...

CWF-145, a synthetic 2-phenyl-4-quinolone derivative exerted potent cytotoxicity against prostate cancer. CWF-145 inhibited prostate cancer cell lines PC-3, DU-145 and LNCap. It had a very low IC50 about 200 nM against castrate-resistant prostate cancer (CRPC) PC-3. We found that CWF-145 had a similar effect to clinical trial antimitotic agents in cancer cells and normal cells. CWF-145 arrested cell cycle at G2/M phase by binding to the β-tubulin at the colchicine-binding site then disrupted microtubule polymerization...

Previously, we reported that 6-(3,4-dihydro-1H-isoquinolin-2-yl)-N-(6-methylpyridin-2-yl) nicotinamide (DIMN) analogues inhibited the growth of prostate cancer cells as an anti-androgenic compound. In the present study, we evaluated cytotoxic effects of these DIMN derivatives and found that DIMN-26 most potently inhibited the proliferation of the LNCap-LN3 androgen-dependent and DU145 androgen-independent prostate cancer cells through induction of G2/M phase cell cycle arrest and subsequent apoptosis. The G2/M phase arrest was found due to increases in the activation of cdc2 (also known as cyclin-dependent kinase 1, CDK1)/cyclin B1 complex...

Prostate cancer (Pca) is one of the most common types of cancer for elder men. Aberrant expression of epidermal growth factor receptor (EGFR) and EGFR downstream signaling have been known to contribute to disease progression in prostate cancer. EGF-stimulated EGFR is internalized and the process of endocytic degradation of EGFR mediates its signaling which is frequently dysregulated in many kinds of cancer. In the present study, we demonstrated that endophilin B1 expression was inhibited and EGFR expression was significantly increased in prostate cancer cell lines...

BACKGROUND: Nowadays, highly specific aptamers generated by cell SELEX technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. Prostate Specific Membrane Antigen (PSMA), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. The aim of the present study was to select single-stranded DNA aptamers against LNCap cells highly expressing PSMA, using cell-SELEX method which can be used as a diagnostic tool for the detection of prostate cancer cells...

Prostate cancer (PCa) is known to develop resistance to chemotherapy. Growth arrest-specific 6 (GAS6), plays a role in tumor progression by regulating growth in many cancers. Here, we explored how GAS6 regulates the cell cycle and apoptosis of PCa cells in response to chemotherapy. We found that GAS6 is sufficient to significantly increase the fraction of cells in G1 and the duration of phase in PCa cells. Importantly, the effect of GAS6 on G1 is potentiated during docetaxel chemotherapy. GAS6 altered the levels of several key cell cycle regulators, including the downregulation of Cyclin B1 (G2 /M phase), CDC25A, Cyclin E1, and CDK2 (S phase entry), while the upregulation of cell cycle inhibitors p27 and p21, Cyclin D1, and CDK4...

Recent studies indicate that a high level of nesfatin-1/Nucleobindin-2 (NUCB-2) is associated with poor outcome and promotes cell migration in breast cancer and prostate cancer. However, the role of NUCB2 is not well known in colon cancer. In this study, NUCB-2 level in colon cancer tissue was higher than that in non-tumor tissue. Suppression of NUCB-2 in a colon cancer cell line SW620 inhibited migration and invasion. The microarray analysis showed that low expression level of transcription factor ZEB1 in NUCB-2 knockdowned SW620 cells...

Despite state of the art cancer diagnostics and therapies offered in clinic, prostate cancer (PCa) remains the second leading cause of cancer-related deaths. Hence, more robust therapeutic/preventive regimes are required to combat this lethal disease. In the current study, we have tested the efficacy of Andrographolide (AG), a bioactive diterpenoid isolated from Andrographis paniculata, against PCa. This natural agent selectively affects PCa cell viability in a dose and time-dependent manner, without affecting primary prostate epithelial cells...

Atrazine, a widely used pesticide, is frequently detected in soil and surface water, which alarms epidemiologists and medical professionals because of its potential deleterious effects on health. Indeed, atrazine is a potent endocrine disruptor that increases aromatase expression in some human cancer cell lines. Both animal and human studies have suggested that atrazine is possibly carcinogenic, although discrepant results have been reported. In this study, RM1 cells were used to explore the atrazine effects on prostate cancer...

The Eph receptors are transmembrane proteins that belong to the receptor tyrosine kinases superfamily. Elevated Eph/ephrin expression levels have been associated with angiogenesis and tumor vasculature in many types of human cancers, including breast, lung, and prostate cancers, melanoma, and leukemia. In glioblastoma (GBM), the dysregulated expression of Eph receptors and of corresponding ephrin ligands has been associated with higher tumor grade and poor prognosis making them effective targets for therapeutic drugs...
