TOP STORY
MicroRNA-1 Is a Candidate Tumor Suppressor and Prognostic Marker in Human Prostate Cancer
Researchers’ findings indicate that microRNA-1 acts as a tumor suppressor in prostate cancer by influencing multiple cancer-related processes and by inhibiting cell proliferation and motility. [Nucleic Acids Res] Abstract

LABORATORY RESEARCH

Efficient Delivery of Sticky siRNA and Potent Gene Silencing in a Prostate Cancer Model Using a Generation 5 Triethanolamine-Core PAMAM Dendrimer
In the present study, researchers demonstrate that a triethanolamine-core PAMAM dendrimer of generation 5 is able to deliver sticky siRNAs bearing complementary An/Tn 3′-overhangs effectively to a prostate cancer model in vitro and in vivo and produce potent gene silencing of the heat shock protein 27, leading to a notable anticancer effect. [Mol Pharm] Abstract

PTEN Regulates PDGF Ligand Switch for PDGF Receptor β Signaling in Prostate Cancer
In this study, researchers examined the role of the tumor suppressor phosphatase and tensin homologue deleted on chromosome 10 (PTEN) in the regulation of platelet-derived growth factor (PDGF) expression levels using both a prostate-specific, conditional PTEN-knockout mouse model and mouse prostate epithelial cell lines established from these mice. [Am J Pathol] Abstract

Salinomycin Inhibits Prostate Cancer Growth and Migration via Induction of Oxidative Stress
Researchers studied the growth inhibitory potential of salinomycin in a panel of prostate cells. [Br J Cancer] Abstract

Prostate Cancer Cell Lines under Hypoxia Exhibit Greater Stem-Like Properties
In this report, researchers investigated the effects of hypoxia on human prostate cancer cell lines, PC-3 and DU145. [PLoS One] Abstract

High Mobility Group Protein AT-Hook 1 (HMGA1) Is Associated with the Development of Androgen Independence in Prostate Cancer Cells
In this study, researchers evaluate the effect of HMGA1 on developing androgen independency, which is associated with the progression of prostate cancer. [Prostate] Abstract

Cediranib Inhibits Both the Intraosseous Growth of PDGF D-Positive Prostate Cancer Cells and the Associated Bone Reaction
In the current study, scientists developed a clinically relevant in vivo intraosseous tumor model overexpressing the platelet-derived growth factor D (PDGF D) to test the efficacy of a newly characterized vascular endothelial growth factor receptor/PDGFR inhibitor, cediranib. [Prostate] Abstract

LNCaP Prostate Cancer Cells with Autocrine Interleukin-6 (IL-6) Expression Are Resistant to IL-6-Induced Neuroendocrine Differentiation Due to Increased Expression of Suppressors of Cytokine Signaling
LNCaP-S17, an LNCaP subline that secretes IL-6, and LNCaP-C3, a control subline that does not express IL-6, were analyzed for IL-6-induced neuroendocrine differentiation, activation of JAK2 and STAT3 pathways, and expression of IL-6/IL-6R signaling proteins and downstream target genes. [Prostate] Abstract

Deficiency of DNA Repair Nuclease ERCC1-XPF Promotes Prostate Cancer Progression in a Tissue Recombination Model
Researchers examined the effect of excision repair cross complementing (Ercc1) gene deletion in the development of prostate cancer in a prostate recapitulation model. [Prostate] Abstract

T Cells Localized to the Androgen-Deprived Prostate Are TH1 and TH17 Biased
Researchers investigated the phenotype and cytokine expression of T cells at various time points in the prostates of Lewis rats following surgical castration, and used adoptive transfer of prostate-infiltrating lymphocytes to determine whether the infiltration by T cells was mediated by effects of castration on the prostate or lymphocytes. [Prostate] Abstract


CLINICAL RESEARCH

Sixteen-Year Longitudinal Changes in Serum Prostate-Specific Antigen Levels: The Olmsted County Study
The objective of this study was to determine the distribution of longitudinal changes in serum prostate-specific antigen levels from a population-based sample of men. [Mayo Clin Proc] Abstract

Weight Change and Prostate Cancer Incidence and Mortality
Scientists investigated associations between reported weight and BMI at age 18 years and measured at study entry, height, weight change between age 18 years and study entry and prostate cancer incidence and mortality. [Int J Cancer] Abstract

Phase II Study of Long-Term Androgen Suppression with Bevacizumab and Intensity-Modulated Radiation Therapy (IMRT) in High-Risk Prostate Cancer
Researchers report a Phase II trial assessing the acute and late toxicities of IMRT, long-term androgen suppression, and bevacizumab in patients with high-risk localized prostate cancer. [Int J Radiat Oncol Biol Phys] Abstract

Phase I Trial of Tremelimumab in Combination with Short-Term Androgen Deprivation in Patients with PSA-Recurrent Prostate Cancer
Researchers hypothesized that treatment with androgen deprivation, followed by an anti-CTLA-4 antibody, could augment a tumor-specific immune response elicited by androgen deprivation. [Cancer Immunol Immunother] Abstract
