LABORATORY RESEARCH GATA2 Facilitates Steroid Receptor Coactivator Recruitment to the Androgen Receptor Complex Researchers demonstrate that GATA-binding protein 2 (GATA2) directly promotes expression of both full-length and splice-variant androgen receptor (AR), resulting in a strong positive correlation between GATA2 and AR expression in both prostate cancer cell lines and patient specimens. [Proc Natl Acad Sci USA] Abstract The Systemic Delivery of an Oncolytic Adenovirus Expressing Decorin Inhibits Bone Metastasis in a Mouse Model of Human Prostate Cancer Scientists created Ad.dcn, a recombinant oncolytic adenovirus carrying the human decorin gene. Infection of PC-3 and DU-145, the human prostate tumor cells, with Ad.dcn or a non-replicating adenovirus Ad(E1-).dcn resulted in decorin expression; Ad.dcn produced high viral titers and cytotoxicity in human prostate tumor cells. [Gene Ther] Abstract Omega-3 Fatty Acids and Other FFA4 Agonists Inhibit Growth Factor Signaling in Human Prostate Cancer Cells Scientists examined effects of omega-3 fatty acids (n-3 FAs) in human prostate cancer cell lines. Initial studies established that the long-chain n-3 FAs, eicosapentaenoic acid and docosahexaenoic acid, inhibit proliferation of DU145 cells in response to lysophosphatidic acid, a mitogenic lipid mediator. [J Pharmacol Exp Ther] Abstract | Full Article A Small Molecule Inhibitor of ETV1, YK-4-279, Prevents Prostate Cancer Growth and Metastasis in a Mouse Xenograft Model SCID-beige mice were subcutaneously implanted with fusion-positive LNCaP-luc-M6 and fusion-negative PC-3M-luc-C6 tumors. Animals were treated with YK-4-279, and its effects on primary tumor growth and lung metastasis were evaluated. [PLoS One] Full Article | Press Release P2X7 Mediates ATP-Driven Invasiveness in Prostate Cancer Cells Scientists demonstrated that P2X7 was highly expressed in some prostate cancer cells. Down-regulation of P2X7 by siRNA significantly attenuated ATP- or BzATP-driven migration and invasion of prostate cancer cells in vitro, and inhibited tumor invasiveness and metastases in nude mice. [PLoS One] Full Article Elevated Expression of Glutaminase Confers Glucose Utilization via Glutaminolysis in Prostate Cancer Researchers show the loss of glutaminase function by RNA interference or inhibitor diminished the rates of glucose utilization, growth and invasiveness of prostate cancer cells. [Biochem Biophys Res Commun] Abstract SUV39H1/H3K9me3 Attenuates Sulforaphane-Induced Apoptotic Signaling in PC3 Prostate Cancer Cells Investigators demonstrated that sulforaphane induces posttranslational modification of histone methyltransferase SUV39H1 in metastatic, androgen receptor-negative PC3 prostate cancer cells. [Oncogenesis] Full Article CLINICAL RESEARCH The Association of an Elevated Plasma Fibrinogen Level with Cancer-Specific and Overall Survival in Prostate Cancer Patients In recent studies, an elevated plasma fibrinogen level has been associated with poor prognosis in different types of cancer. Researchers analyzed the prognostic impact of an elevated fibrinogen level in prostate cancer patients. [World J Urol] Abstract Efficacy and Toxicity of Molecular Targeted Therapies in Combination with Docetaxel for Metastatic Castration-Resistant Prostate Cancer: A Meta-Analysis of Phase III Randomized Controlled Trials Scientists conducted a meta-analysis to assess the efficacy and toxicity of the addition of molecular targeted agents to docetaxel-based chemotherapy for the treatment of metastatic castration-resistant prostate cancer.
