Bone-Induced c-Kit Expression in Prostate Cancer: A Driver of Intraosseous Tumor Growth
Researchers showed that c-kit expression promotes migration and invasion of prostate cancer (PCa) cells. They also found that c-kit expression in PCa cells parallels BRCA2 downregulation. [Int J Cancer] Abstract

Effects of Functional Genetic Polymorphisms in the CYP19A1 Gene on Prostate Cancer Risk and Survival
Scientists investigated the functions of CYP19A1 polymorphisms and their associations with prostate cancer risk and clinical outcome. The functions of single nucleotide polymorphisms were determined by reporter gene assays in PC3 and DU145 cell lines. [Int J Cancer] Abstract

The Combination of the Prodrugs Perforin-CEBPD and Perforin-Granzyme B Efficiently Enhances the Activation of Caspase Signaling and Kills Prostate Cancer
Researchers showed that the combination of a perforin (PF)-CCAAT/enhancer binding protein delta (CEBPD) prodrug and a PF-granzyme B prodrug showed an additive effect in triggering the apoptotic pathway and enhancing apoptosis in prostate cancer cells. [Cell Death Dis] Full Article

Pigment Epithelium-Derived Factor Expression Prolongs Survival and Enhances the Cytotoxicity of Low-Dose Chemotherapy in Castration-Refractory Prostate Cancer
Scientists report the anti-tumor effect of the angio-inhibitory pigment epithelium-derived factor in the metastatic LNCaP-derivative castration-refractory prostate cancer CL1 model and explore PEDF anti-neoplasic efficacy in combination with low-dose chemotherapy. [Cell Death Dis] Full Article

COX-2 Inhibitors Arrest Prostate Cancer Cell Cycle Progression by Down-Regulation of Kinetochore/Centromere Proteins
Treatment with the COX-2 inhibitors celecoxib and CAY10404 or knockdown of COX-2 significantly inhibited prostate cancer cell proliferation. [Prostate] Abstract

NPM1 Silencing Reduces Tumor Growth and MAPK Signaling in Prostate Cancer Cells
To better understand nucleophosmin (NPM1) functions in prostate cancer cells, researchers sought to characterize its impact on prostate cancer cells behavior and decipher the mechanisms by which it may act. They showed that NPM1 favors prostate tumor cell migration, invasion and colony forming. [PLoS One]

Distinct Phenotypes of Human Prostate Cancer Cells Associate with Different Adaptation to Hypoxia and Pro-Inflammatory Gene Expression
Scientists explored how different features, including differentiation and aggressiveness, of prostate tumor cell lines impact on the hypoxic remodeling of pro-inflammatory gene expression and malignancy. [PLoS One]

AKT and AMPK Activation after High-Fat and High-Glucose In Vitro Treatment of Prostate Epithelial Cells
Investigators analyzed the proliferation profile of nonmalignant human prostate epithelial cells after exposure to elevated levels of fat and glucose. [Horm Metab Res] Abstract

CLINICAL RESEARCH

A Randomized Phase II Study of Cediranib Alone versus Cediranib in Combination with Dasatinib in Docetaxel Resistant, Castration Resistant Prostate Cancer Patients
Phase II studies of cediranib and dasatinib in castration-resistant prostate cancer (CRPC) have shown single agent activity. Docetaxel-pretreated CRPC patients were randomized to arm A: cediranib alone versus arm B: cediranib plus dasatinib given orally on four-week cycles. [Invest New Drugs] Abstract

The Impact of Multiparametric Pelvic Magnetic Resonance Imaging on Risk Stratification in Patients With Localized Prostate Cancer
Scientists determined the impact of multiparametric magnetic resonance imaging of the prostate on established risk stratification criteria in patients with clinically localized adenocarcinoma of the prostate. [Urology] Abstract

Prostate Cancer Foundation Announces Over $8.4 Million Donation to Advance Prostate Cancer Research
The Prostate Cancer Foundation (PCF) has received over $8.4 million from its partner Movember raising vital funds and awareness for men’s health. PCF will allocate the over $8.4 million to find better treatments and ultimately a cure, by funding first in field research. [The Prostate Cancer Foundation] Press Release
