ERG Induces Taxane Resistance in Castration-Resistant Prostate Cancer
Taxanes are the only chemotherapies used to treat patients with metastatic castration-resistant prostate cancer (CRPC). Scientists show that ​ERG overexpression in in vitro and in vivo models of CRPC is associated with decreased sensitivity to taxanes. [Nat Commun] Full Article

The Long Non-Coding RNA PCAT-1 Promotes Prostate Cancer Cell Proliferation through cMyc12
Researchers describe a role for the oncogenic long non-coding RNAs PCAT-1 in prostate cancer proliferation through cMyc. They found that PCAT-1-mediated proliferation is dependent on cMyc protein stabilization, and using expression profiling, they observed that cMyc is required for a subset of PCAT-1-induced expression changes.

Hsp90 C-Terminal Inhibitors Exhibit Anti-Migratory Activity by Disrupting the Hsp90α/Aha1 Complex in PC3-MM2 Cells
Scientists report that Hsp90α associates with the Aha1 co-chaperone and found this complex to localize in secretory vesicles and at the leading edge of migrating cells. Knockdown of Hsp90α resulted in a defect in cell migration. [ACS Chem Biol] Abstract

Prostate Cancer Cells Induce Osteoblastic Differentiation via Semaphorin 3A
Researchers investigated whether prostate cancer cells can mediate osteoblastic activity through semaphorin 3A (Sema 3A). They cultured osteoprogenitor MC3T3-E1 cells in prostate cancer-conditioned medium, and analyzed levels of Sema 3A protein in diverse prostate cancer cell lines to identify cell lines in which Sema 3A production showed a positive correlation with osteo-stimulation. [Prostate] Abstract

[18F]Fluoromethylcholine as a Chemotherapy Response Read-Out in Prostate Cancer Cells
The effects of docetaxel and cabazitaxel on viable tumor cell number were explored in four prostate cancer cell lines. Cellular uptake of 2-deoxy-2-[18F]fluoro-D-glucose and [18F]fluoromethylcholine was compared with the effects measured using sulforhodamine B assay, cell counting and colony formation assay, as proximators of viable tumor cell number. [Mol Imaging Biol] Abstract

MicroRNA-224 and Its Target CAMKK2 Synergistically Influence Tumor Progression and Patient Prognosis in Prostate Cancer
Calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2) was identified as a target gene of microRNA (miR)-224. Then, scientists found that enforced expression of miR-224 could suppress prostate cancer cell proliferation and cell cycle by regulating the expression of CAMKK2 in vitro. [Tumor Biol] Abstract

Boric Acid Induces Cytoplasmic Stress Granule Formation, eIF2α Phosphorylation, and ATF4 in Prostate DU-145 Cells
Scientists report that treatment of DU-145 prostate cells with physiological levels of boric acid induces endoplasmic reticulum stress with the formation of stress granules and mild activation of eIF2α, GRP78/BiP, and ATF4. [Biometals] Full Article


Denosumab for the Prevention of Skeletal Complications in Metastatic Castration-Resistant Prostate Cancer: Comparison of Skeletal-Related Events and Symptomatic Skeletal Events
In a Phase III trial in patients with castration-resistant prostate cancer and bone metastases, denosumab was superior to zoledronic acid in reducing skeletal-related events. Researchers reassessed the efficacy of denosumab using symptomatic skeletal events as a prespecified exploratory endpoint. [Ann Oncol]

Bevacizumab and the Risk of Arterial and Venous Thromboembolism in Patients with Metastatic, Castration-Resistant Prostate Cancer Treated on Cancer and Leukemia Group B (CALGB) 90401 (Alliance)
The authors investigated the association of bevacizumab treatment and clinical factors with arterial thromboembolism/venous thromboembolism risk in patients who were treated on Cancer and Leukemia Group B (CALGB) trial 90401. Patients with metastatic, castration-resistant prostate cancer were randomized to receive docetaxel and prednisone with or without bevacizumab once every 21 days. [Cancer] Abstract

Role of the Staphylococcal Nuclease and Tudor Domain Containing 1 in Oncogenesis
The staphylococcal nuclease and tudor domain containing 1 (SND1) is a multifunctional protein overexpressed in breast, prostate, colorectal and hepatocellular carcinomas and malignant glioma. The authors describe the crucial role of SND1 in cancer development and progression, and highlight SND1 as a potential target for therapeutic intervention. [Int J Oncol] Abstract
