The aim of the present study was to investigate the role of autophagy in celecoxib-induced apoptosis in human hormone-insensitive prostate cancer cell line PC3 cells and to explore the underlying molecular mechanism leading to autophagic activation. A cell viability assay was applied to investigate the effect of various concentrations of celecoxib (0, 40, 60, 80, 100 and 120 µmol/l) on PC3 cell...
In the present study, we investigated if the intracellular Cl(-) affects cell growth and cell cycle progression of androgen-independent prostate cancer PC3 cells. PC3 cells cultured in a medium containing 113 mM Cl(-) for 96 h grew up 9-fold in cell number, while PC3 cells cultured in an 8 mM-Cl(-)-containing culture medium showed complete arrest of cell growth even after culture for 96 h. Expo...
In the recent years, the role of LOX enzymes in the cause of neoplastic diseases such as colorectal, skin, pancreatic and renal cancers has been confirmed. A new series of 1,3,4-thiadiazole derivatives bearing 2-pyridyl moiety was synthesized and their cytotoxicity was assessed using MTT protocol. Enzyme inhibitory activity of prepared compounds was also tested against 15-lipoxygenase-1 as nove...
Here we have developed a hypoxia response element driven imaging strategy that combined the hypoxia-driven expression of two optical reporters with different half-lives to detect temporal changes in hypoxia and hypoxia inducible factor (HIF) activity. For this purpose, human prostate cancer PC3 cells were transfected with the luciferase gene fused with an oxygen-dependent degradation domain (OD...
BACKGROUND The current study was undertaken to characterize the effect of anti-metabolites on inducing CXCL8 signaling and determining whether the constitutive and/or drug-induced CXCL8 signaling in metastatic prostate cancer (CaP) cells modulates their sensitivity to this class of agent. METHODS The response of metastatic CaP cells to 5-Fluorouracil (5-FU), Pemetrexed or Tomudex was determin...
The aim of the present study was to determine the role of androgen receptor in the effect of dexamethasone on cell proliferation and migration of multiple prostate cancer cells. The prostate cancer cell lines LNCaP, 22Rv1, C4‑2 and PC3 were cultured in vitro. For glucocorticoid‑induced experiments, the cells were transferred and cultured in RPMI‑1640 medium with 10% charcoal‑stripped serum from...
PURPOSE Clinical and epidemiologic data suggest that obesity is associated with more aggressive forms of prostate cancer, poor prognosis, and increased mortality. C-terminal-binding protein 1 (CtBP1) is a transcription repressor of tumor suppressor genes and is activated by NADH binding. High calorie intake decreases intracellular NAD(+)/NADH ratio. The aim of this work was to assess the effect...
OBJECTIVES To investigate the effects of serotonin and melatonin (MLT) on the regulation of malignant growth and the activity of serotonin receptors (5HTR1a/-1b) in prostate cancer (PCa) cell lines. MATERIALS AND METHODS In four PCa cell lines (LNCaP, 22RV1, PC3, DU145) and two reference cell lines 5HTR1a and -1b, relative mRNA expression levels were assessed. Different serotonin and MLT rece...
PURPOSE Despite most epidemiologic studies reporting that an increase in milk intake affects the growth of prostate cancer, the results of experimental studies are not consistent. In this study, we investigated the proliferation of prostate cancer cells treated with casein, the main protein in milk. MATERIALS AND METHODS Prostate cancer cells (LNCaP and PC3), lung cancer cells (A459), stomach...
PTTG1 protein, the human securin, has a central role in sister chromatid separation during mitosis, and its altered expression has been reported in many tumor types. Paclitaxel is a widely used chemotherapeutic drug, whose mechanism of action is related to its ability to arrest cells in mitosis and the subsequent induction of the intrinsic apoptotic pathway. By using two prostate cancer cell li...
