LABORATORY RESEARCH

Selective Inhibitory Effect of HPMA Copolymer-Cyclopamine Conjugate on Prostate Cancer Stem Cells
Here, researchers designed an HPMA (N-(2-hydroxypropyl)methacrylamide)-based cyclopamine delivery system as a cancer stem cell-selective macromolecular therapeutic with improved drug solubility and decreased systemic toxicity. [Biomaterials] Abstract

Profiling of Antibody Production Against Xenograft-Released Proteins by Protein Microarrays Discovers Prostate Cancer Markers
This study describes a novel xenograft-based biomarker discovery platform and proves its usefulness in the discovery of serum markers for prostate cancer. [J Proteome Res] Abstract

FOXA1 Promotes Tumor Progression in Prostate Cancer and Represents a Novel Hallmark of Castrate-Resistant Prostate Cancer
Researchers investigated the correlation of forkhead box protein A1 (FOXA1) expression with clinical parameters, prostate-specific antigen relapse-free survival, and hormone receptor expression in a large cohort of prostate cancer patients at different disease stages. [Am J Pathol] Abstract

Progression of Prostate Carcinogenesis and Dietary Methyl Donors: Temporal Dependence
Researchers looked at the effect of excess methyl donors on the growth rate of prostate cancer (PCa) in vivo, the ability of 5-aza-2′-deoxycytidine to demethylate in the presence of excess dietary methyl donors and the effect of in utero feeding of excess methyl donors to the later onset of PCa. [Cancer Prev Res] Abstract

ERG Deregulation Induces PIM1 Over-Expression and Aneuploidy in Prostate Epithelial Cells
Here researchers provide the first evidence for an ERG-mediated PIM1 up-regulation in prostate cells in vitro and in vivo, suggesting a direct effect of ERG transcriptional activity in the alteration of genetic stability. [PLoS One] Abstract

Caveolin-1 Upregulation Contributes to c-Myc-Induced High-Grade Prostatic Intraepithelial Neoplasia and Prostate Cancer
Researchers’ results suggest that caveolin-1 is associated with c-Myc in the development of high-grade prostatic intraepithelial neoplasia and prostate cancer. [Mol Cancer Res] Abstract

MiR-146a Suppresses Tumor Growth and Progression by Targeting EGFR Pathway and in a p-ERK-Dependent Manner in Castration-Resistant Prostate Cancer
Given the emerging roles of microRNA (miRNA) as a key regulator of castration-resistant prostate cancer (CRPC) researchers postulated that miRNA may play a significant role in CRPC formation. [Prostate] Abstract

Hsp90 Inhibitor 17-AAG Inhibits Progression of LuCaP35 Xenograft Prostate Tumors to Castration Resistance
This study addresses whether targeting heat shock protein 90 (Hsp90) regulation of androgen receptor can inhibit prostate cancer progression to castration resistance. [Prostate] Abstract

Phenethyl Isothiocyanate Suppresses Inhibitor of Apoptosis Family Protein Expression in Prostate Cancer Cells in Culture and In Vivo
The present study was designed to determine the role of inhibitor of apoptosis family proteins in phenethyl isothiocyanate-induced apoptosis induction. [Prostate] Abstract

TMPRSS2–ERG-Specific Transcriptional Modulation Is Associated with Prostate Cancer Biomarkers and TGF-Beta Signaling
Researchers studied large-scale gene expression profiles in 47 prostate tumor tissue samples and in 48 normal prostate tissue samples taken from the non-suspect area of clinical low-risk tumors using Affymetrix GeneChip Exon 1.0 ST microarrays. [BMC Cancer] Abstract

CLINICAL RESEARCH

Discrepancy in Prostate Cancer Localization between Biopsy and Prostatectomy Specimens in Patients with Unilateral Positive Biopsy: Implications for Focal Therapy
Scientists evaluated the discrepancy in prostate cancer localization between unilateral positive biopsy and radical prostatectomy. [Prostate] Abstract

Assessing the Clinical Role of Genetic Markers of Early-Onset Prostate Cancer Among High-Risk Men Enrolled in Prostate Cancer Early Detection
Scientists evaluated clinical information from six polymorphisms associated with early-onset prostate cancer (PCA) in a longitudinal cohort of high-risk men enrolled in PCA early detection with significant African American participation. [Cancer Epidemiol Biomarkers Prev] Abstract

Correlations Among Cardiovascular Risk Factors, Prostate Blood Flow, and Prostate Volume in Patients with Clinical Benign Prostatic Hyperplasia
The objective of this study was to investigate the relationships among the cardiovascular risk factors, prostate blood flow, and prostate volume in patients with clinical benign prostatic hyperplasia. [Urology] Abstract
