Androgen Receptor Interacting Protein HSPBAP1 Facilitates Growth of Prostate Cancer Cells in Androgen-Deficient Conditions
Investigators performed an RNAi screen on 2068 genes, including kinases, phosphatases, epigenetic enzymes and other druggable gene targets. High-content cell spot microarray screen was performed in VCaP cells in the presence and absence of androgens with detection of Ki67 and cleaved ADP-ribose polymerase as assays for cell proliferation and apoptosis.

Sortilin Regulates Progranulin Action in Castration-Resistant Prostate Cancer Cells
Scientists show that sortilin is expressed at very low levels in castration-resistant PC3 and DU145 cells. Significantly, enhancing sortilin expression in PC3 and DU145 cells severely diminishes progranulin levels, and inhibits motility, invasion, proliferation and anchorage-independent growth.

Complex Impacts of PI3K/AKT Inhibitors to Androgen Receptor Gene Expression in Prostate Cancer Cells
Four human prostate cancer cell lines with different genetic backgrounds were treated with five PI3K/AKT inhibitors and or AKT siRNA. PI3K/AKT inhibitors had various impacts on androgen receptor (AR) protein expressions primarily through alterations of AR gene transcription initiation and RNA splicing. [PLoS One]

TNFα-Mediated Loss of β-Catenin/E-Cadherin Association and Subsequent Increase in Cell Migration Is Partially Restored by NKX3.1 Expression in Prostate Cells
Altered β-catenin signaling upon TNFα exposure, and relation to loss of function of the tumor suppressor NKX3.1 was examined in prostate cancer cells. Researchers used an in vitro prostate inflammation model to demonstrate altered sub-cellular localization of β-catenin following increased phosphorylation of Akt^(S473) and GSK3β^(S9).

RNA-Seq Profiling of a Radiation Resistant and Radiation Sensitive Prostate Cancer Cell Line Highlights Opposing Regulation of DNA Repair and Targets for Radiosensitization
Using an in vitro model to screen for novel biomarkers of radioresistance, transcriptome analysis of a radioresistant and radiosensitive prostate cancer cell line was performed. [BMC Cancer] Abstract | Full Article

The Anti-Proliferative Effects of Enterolactone in Prostate Cancer Cells: Evidence for the Role of DNA Licencing Genes, mi-R106b Cluster Expression, and PTEN Dosage
Researchers investigated what concentration(s) of enterolactone can restrict proliferation in multiple stages of prostate cancer using an in vitro model system of prostate disease. [Nutrients] Full Article

Angiopoietin-Like Protein 2 Induces Androgen-Independent and Malignant Behavior in Human Prostate Cancer Cells
Androgen-dependent LNCaP and androgen-independent LNCaP/AI cells, respectively, were cultured in fetal bovine and charcoal-stripped medium. Cell proliferation, androgen dependence, migration and invasion, respectively, were examined under the overexpression and knockdown of angiopoietin-like protein 2 (ANGPTL2) by transfection of ANGPTL2 cDNA and its small-interfering RNA.

CLINICAL RESEARCH

Chromosomal Instability in Cell-Free DNA Is a Serum Biomarker for Prostate Cancer
DNA was extracted from serum of 204 patients with prostate cancer, 207 male controls, and patients with benign hyperplasia and prostatitis. DNA was amplified by use of random primers, tagged with molecular identifiers, sequenced on a SOLID system, and aligned to the human genome. [Clin Chem] Abstract

A Phase II Trial Evaluating the Efficacy and Safety of Efavirenz in Metastatic Castration-Resistant Prostate Cancer
Preclinical studies demonstrated that non-nucleoside reverse transcriptase inhibitors used for the treatment of HIV could antagonize tumor development. This led the authors to assess the efficacy of efavirenz in patients with metastatic castration-resistant prostate cancer in a multicenter Phase II study. [Oncologist]
