Cholesterol-Metabolism Study Suggests New Diagnostic, Treatment Approach for Aggressive Prostate Cancer
Researchers have discovered a link between prostate cancer aggressiveness and the accumulation of a compound produced when cholesterol is metabolized in cells, findings that could bring new diagnostic and treatment methods.

Ablation of the Oncogenic Transcription Factor ERG by Deubiquitinase Inhibition in Prostate Cancer
Scientists showed that ubiquitin-specific peptidase 9, X-linked, a deubiquitinase enzyme, binds E-twenty-six related gene (ERG) in VCaP prostate cancer cells expressing TMPRSS2-ERG and deubiquitinates ERG in vitro. [Proc Natl Acad Sci USA] Abstract | Full Article | Press Release

TR4 Nuclear Receptor Functions as a Tumor Suppressor for Prostate Tumorigenesis via Modulation of DNA Damage/Repair System
Knocking down testicular nuclear receptor 4 (TR4) in human RWPE1 and mouse mPrE normal prostate cells promoted tumorigenesis under carcinogen challenge, suggesting TR4 may play a suppressor role in prostate cancer initiation. [Carcinogenesis] Abstract

Arachidonic Acid Induction of Rho-Mediated Transendothelial Migration in Prostate Cancer
Microscopic analysis and measurement of adhesion and invasion of prostate cancer cells through bone marrow endothelial cells was undertaken with arachidonic acid stimulation and/or simvastatin treatment. [Br J Cancer] Abstract

Exposure to Bisphenol A Correlates with Early-Onset Prostate Cancer and Promotes Centrosome Amplification and Anchorage-Independent Growth In Vitro
In vitro studies examined centrosomal abnormalities, microtubule nucleation, and anchorage-independent growth in four prostate cancer cell lines and two immortalized normal prostate epithelial cell lines. Exposure to low doses of bisphenol A increased the percentage of cells with centrosome amplification two- to eight-fold. [PLoS One] Full Article | Press Release

Comparative Genomic and Transcriptomic Analyses of LNCaP and C4-2B Prostate Cancer Cell Lines
Exome sequencing detected 2188 and 3840 mutations in LNCaP and C4-2B cells, respectively, of which 1784 were found in both cell lines. Surprisingly, the parental LNCaP cells have over 400 mutations that were not found in the C4-2B genome. [PLoS One] Full Article

GPNMB/OA Protein Increases the Invasiveness of Human Metastatic Prostate Cancer Cell Lines DU145 and PC3 through MMP-2 and MMP-9 Activity
Researchers investigated the role of non-metastatic glycoprotein melanoma protein B (GPNMB)/osteoactivin (OA) in the progression of human metastatic DU145 and PC3 prostate cancer cells. [Exp Cell Res] Abstract

Development and Screening of a Series of Antibody-Conjugated and Silica-Coated Iron Oxide Nanoparticles for Targeting the Prostate-Specific Membrane Antigen
Antibody and prostate-specific membrane antigen (PSMA)-specific targeting of the optimized nanoparticle was evaluated using an isogenic PSMA-positive and PSMA-negative cell line pair. [ChemMedChem] Abstract

Rsf-1 Overexpression in Human Prostate Cancer, Implication as a Prognostic Marker
Researchers analyzed the expression pattern of Rsf-1 in human prostate cancer tissues and found that Rsf-1 was overexpressed in 45% of prostate cancer specimens. In addition, small interfering RNA knockdown in DU145 cells with high endogenous Rsf-1 expression decrease cell proliferation, colony formation, and invasion. [Tumor Biol] Abstract


Randomized Controlled Trial of Early Zoledronic Acid in Men with Castration-Sensitive Prostate Cancer and Bone Metastases: Results of CALGB 90202 (Alliance)
This Phase III study evaluated the efficacy and safety of earlier treatment with zoledronic acid in men with castration-sensitive metastatic prostate cancer. [J Clin Oncol] Abstract

Quantification of Skeletal Metastases in Castrate Resistant Prostate Cancer Predicts Progression Free and Overall Survival
Scientists reported a simplified and effective method for substratification of M1 castrate resistant prostate cancer by correlating progression free and overall survival with simple numeric quantification of skeletal metastases. [BJU Int] Abstract

Current Trends for the Use of Androgen Deprivation Therapy in Conjunction with Radiotherapy for Patients with Unfavorable Intermediate-Risk, High-Risk, Localized, and Locally Advanced Prostate Cancer
This review examines the clinical evidence underpinning the use of androgen deprivation therapy and radiotherapy among patients with high-risk localized and locally advanced disease in the United States. This review also considers the rationale for moving from traditional luteinizing hormone-releasing hormone agonists to more recently developed gonadotrophin-releasing hormone antagonists.

Dendreon Announces Plans to Make PROVENGE® Commercially Available in Europe
Dendreon Corporation announced that it plans to make PROVENGE® available in Europe, beginning with Germany and the United Kingdom. PROVENGE is approved in the European Union for the treatment of asymptomatic or minimally symptomatic metastatic (non-visceral) castrate resistant prostate cancer in male adults in whom chemotherapy is not yet clinically indicated. [Dendreon Corporation] Press Release

Saskatchewan Grants Access to ZYTIGA® for Men with Metastatic Prostate Cancer Prior to Chemotherapy
The inclusion of ZYTIGA® (abiraterone acetate) on the Saskatchewan Cancer Agency Drug Formulary makes it the fourth province, following British Columbia, Québec and Ontario, to fund ZYTIGA® through a provincial drug benefit plan for the treatment of metastatic castration-resistant prostate cancer in men who are asymptomatic or mildly symptomatic after failure of androgen deprivation therapy.
