PURPOSE We have synthesized and evaluated in vivo 2-(3-{1-carboxy-5-[(6-[(18)F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}-ureido)-pentanedioic acid, [(18)F]DCFPyL, as a potential imaging agent for the prostate-specific membrane antigen (PSMA). PSMA is upregulated in prostate cancer epithelia and in the neovasculature of most solid tumors. EXPERIMENTAL DESIGN [(18)F]DCFPyL was synthesized in t...
BACKGROUND Thapsigargin (TG) is a potent inhibitor of sarcoplasmic/endoplasmic reticulum Ca2+ ATPases (SERCAs). TG-based prodrugs are being developed for the treatment of prostate cancer (PC). To develop optimal TG-based therapeutics it is important to understand the mechanisms of resistance to TG that may potentially occur in cancer cells. METHODS DU145/TG and PC3/TG cells were derived from ...
Prostate cancer remains the second leading cause of cancer deaths among American men. Early diagnosis increases survival rate in patients; however, treatments for advanced disease are limited to hormone ablation techniques and palliative care. Thus, new methods of treatment are necessary for inhibiting prostate cancer disease progression. Here, we have shown that miRNA-29b (miR-29b) expression ...
We previously reported that the transcription factor Zinc Finger Protein 143 (ZNF143) regulates the expression of genes associated with cell cycle and cell division, and that downregulation of ZNF143 induces cell cycle arrest at G2/M. To assess the function of ZNF143 expression in the cell cycle, we established two cells with forced expression of ZNF143 derived from PC3 prostate cancer cell lin...
Prostate cancer is one of the most common malignancies in men. Epidemiological and experimental studies have revealed that stromal cells of the tumour microenvironment contribute to the development of prostate cancers, while long-chain n-3 PUFA-enriched diets reduce the risk of this tumour histotype. These findings prompted us to investigate whether DHA, an n-3 PUFA, may abrogate differentiatio...
Hepatocyte growth factor (HGF) is a glycoprotein that induces prostate cancer cell proliferation, migration and invasion. The activation of transient receptor potential canonical 6 (TRPC6) channels is considered important in promoting prostate cancer cell proliferation. In this study, we assessed the role of endogenous TRPC6 channels in the HGF-induced cell proliferation of prostate cancer. Rev...
AIM To evaluate the antiproliferative activity of contragestazol (DL111-IT) on the human prostate cancer cell line PC3 in vitro and in vivo and to elucidate its potential molecular mechanisms. METHODS The cell killing ability of DL111-IT was measured by the 3-(4,5-dimethylthia-zol,2-yl)-2,5-diphenyltetrazolium bromide (MTT) reagent assay method and the tumor xenograft model. The cell cycle wa...
Hypoxia-inducible factor (HIF)-1α has been reported to be associated with malignancy in a number of types of cancer. However, the role of HIF-1 α in the regulation of prostate cancer (PCa) growth has yet to be elucidated. The present study aimed to investigate the effect of HIF-1α on the biological characteristics of the PCa PC3 cell line. Full-length (fL) HIF-1α and dominant-negative (dn) HIF-...
Epithelial cells lining the prostate acini release, in a regulated manner (exocytosis), nanosized vesicles called prostasomes that belong to the exosome family. Prostate cancer cells have preserved this ability to generate and export exosomes to the extracellular space. We previously demonstrated that human prostasomes have an ATP-forming capacity. In this study, we compared the capacity of ext...
Terazosin is one of classic quinazoline-based selective α1-adrenoreceptor antagonists, which is usually used for the treatment of benign prostate hyperplasia (BPH) patients. Several evidences suggest that terazosin can induce apoptosis of prostatic cancer cells in vitro and suppress prostatic tumor growth in vivo, but molecular mechanism contributing to these processes has not yet been fully el...
