TOP STORY

miR-205 Regulates Basement Membrane Deposition in Human Prostate: Implications for Cancer Development
Scientists demonstrated that therapeutic replacement of microRNA-205 (miR-205) in prostate cancer cells can restore basement membrane deposition and three-dimensional organization into normal-like acinar structures, thus hampering cancer progression. [Cell Death Differ] Abstract

PUBLICATIONS (Ranked by Impact Factor of the Journal)

LABORATORY RESEARCH

miRNA-708 Control of CD44+ Prostate Cancer Initiating Cells
Investigators report that miR-708 is a key negative regulator of a CD44+ subpopulation of prostate cancer cells, with important implications for diagnosis and prognosis of this disease. [Cancer Res] Abstract

Regional Cell Proliferation in Microdissected Human Prostate Specimens after Heavy Water-Labeling In Vivo: Correlation with Prostate Epithelial Cells Isolated from Seminal Fluid
Researchers described two novel in vivo metrics of cell proliferation in men with prostate neoplasia. [Clin Cancer Res] Abstract

Targeting Fibroblast Growth Factor Receptor Signaling Inhibits Prostate Cancer Progression
Investigators determined whether targeting fibroblast growth factor receptor (FGFR) signaling from all four FGFRs would have in vitro activities consistent with inhibition of tumor progression and would inhibit tumor progression in vivo.
[Clin Cancer Res] Abstract

Ack1 Mediated Androgen Receptor Phosphorylation Modulates Radiation Resistance in Castration
Resistant Prostate Cancer

Scientists demonstrated that phosphorylated tyrosine-267-androgen receptor is recruited to the ataxia telangiectasia mutated (ATM) enhancer in Ack1 dependent manner to upregulate ATM expression. [J Biol Chem] Full Article

Effect of a Low-Fat Diet Combined with IGF-1 Receptor Blockade on 22Rv1 Prostate Cancer Xenografts
Investigators hypothesized that a low-fat diet combined with IGF-I receptor (IGF-1R) blockade would cause additive inhibition of prostate cancer growth and offset possible untoward metabolic effects of IGF-1R blockade antibody therapy. [Mol Cancer Ther] Abstract

Caffeic Acid Phenethyl Ester Suppresses the Proliferation of Human Prostate Cancer Cells through Inhibition of p70S6K and Akt Signaling Networks
Investigators took a systematic approach to uncover the effects of caffeic acid phenethyl ester from hours to days on the signaling networks in human prostate cancer cells. [Cancer Prev Res]
Abstract | Press Release

Osteoblast-Secreted Collagen Upregulates Paracrine Sonic Hedgehog Signaling by Prostate Cancer Cells and Enhances Osteoblast Differentiation
Researchers investigated the formation of a collagen matrix by osteoblasts cultured with prostate cancer cells, and its effects on interactions between prostate cancer cells and osteoblasts. [Mol Cancer] Full Article

Anti-Inflammatory Effect of Androgen Receptor Activation in Human BPH Cells
Scientists investigated whether hypogonadism was associated with more severe benign prostatic hyperplasia (BPH) inflammation and the in vitro effect of the selective androgen receptor agonist dihydrotestosterone on cultures of stromal cells derived from BPH patients. [J Endocrinol] Abstract

Increased Expression of Basic Helix Loop Helix Transcription Factor E2A (TCF3) in Prostate Cancer Promotes Proliferation and Confers Resistance to Doxorubicin Induced Apoptosis
Researchers demonstrated for the first time that TCF3 could in fact acts as a tumor promoter in prostate cancer. [Biochem Biophys Res Commun] Abstract

CLINICAL RESEARCH

Conformal Postoperative Radiotherapy in Patients with Positive Resection Margins and/or pT3-4 Prostate Adenocarcinoma

Scientists aimed to evaluate outcome and toxicity of high-dose conformal radiotherapy after radical prostatectomy. [Int J Radiat Oncol Biol Phys] Abstract

Multiparametric Magnetic Resonance Imaging of the Prostate Can Improve the Predictive Value of the Urinary Prostate Cancer Antigen 3 Test in Patients with Elevated Prostate-Specific Antigen Levels and a Previous Negative Biopsy
Researchers aimed to evaluate the role of multiparametric magnetic resonance imaging as an additional diagnostic tool for improving the accuracy of the urinary prostate cancer antigen 3 test in patients with an increase in prostate-specific antigen levels and a previous negative prostate biopsy.
