TOP STORYTRIB1 Induces Macrophages to M2 Phenotype by Inhibiting IKB-Zeta in Prostate Cancer Flow cytometry and enzyme-linked immunosorbent assay were used to examine THP-1 cells cultured in conditioned medium from prostate cancer cells overexpressing TRIB1 and showed that overexpression of TRIB1 promoted the secretion of CXCL2 and interleukin (IL)8 by PC3 cells, which increased the secretion of IL12 by THP-1 cells as well as the expression of CD163 on THP-1 cells.

PUBLICATIONS(Ranked by impact factor of the journal)Epithelial cells showed focal DNA double‐strand breaks (DSB), 8‐oxoguanine, and protein tyrosine‐nitrosylation, fingerprints of exposure to peroxinitrite. Cultured epithelial cells induced M1‐polarization and showed focal DSB and underwent apoptosis. [J Cell Physiol] Abstract UV Light-Inactivated HSV-1 Stimulates Natural Killer Cell-Induced Killing of Prostate Cancer Cells Scientists demonstrated that ultraviolet light–inactivated Herpes Simplex Virus-1 (UV-HSV-1) stimulated peripheral blood mononuclear cells to lyse both androgen-sensitive and androgen-independent prostate cancer cell lines, but not the benign prostatic hyperplastic epithelial cell line, BPH-1, and was 1000–10,000-fold more potent at stimulating this killing than ultraviolet light-inactivated vesicular stomatitis virus, adenovirus, reovirus or cytomegalovirus. [J Immunother] Abstract Enzalutamide was able to radiosensitize both androgen-dependent and androgen-independent human prostate cancer models in cell culture and xenografts in mice, as well as a treatment-resistant patient-derived xenograft. [PLoS One] Full Article Metastatic Prostate Cancer Cells Are Highly Sensitive to 3-Bromopyruvic Acid The authors examined how 3-bromopyruvate affects the survival and mobility of rat and human metastatic prostate cancer cell lines. [Life Sci] Abstract Scientists demonstrated that the perylene derivatives, PM2 and PIPER, could suppress hTERT expression and telomerase activity in the short-term treatment of LNCaP and PC3 prostate cancer cells. [Biol Pharm Bull] Abstract MicroRNA-302a Upregulation Mediates Chemo-Resistance in Prostate Cancer Cells Researchers investigated whether miRNA-302a is involved in mediating chemo-resistance to paclitaxel in prostate cancer, a series of in vitro analyses were performed in paclitaxel-resistant prostate cancer PC-3PR cells and non-resistant prostate cancer PC-3 cells. [Mol Med Rep] Abstract The efficacy of two different oHSVs in prostate cancer sphere-forming cells (PCSCs) was tested alone and in combination with radiation, chemotherapy, and inhibitors of PI3K, Wnt, and NOTCH in vitro, and G47Δ with the PI3K inhibitor BKM120 in a PCSC-derived tumor model in vivo. [Mol Ther Oncolytics] Abstract | Full Article Investigators generated docetaxel-resistant PC/DX25 and DU/DX50 CRPC cells from PC-3 and DU-145 PCa cells, respectively. They investigated the mechanism behind why PC/DX25 and DU/DX50 cells exhibited higher migration and invasion ability.

POLICY NEWSFTC Hits Predatory Scientific Publisher with a $50 Million Fine The Federal Trade Commission (FTC) has won a summary judgement that just might cause some predatory publishers to step back from their business model. An India-based predatory publisher has been hit with a $50 million dollar judgement for deceptive business practices, along with permanent injunctions against most of the activities that made it money. [Ars Technica] Editorial Bioethicists Concerned over Japan’s Chimera Embryo Regulations Japanese regulators have effectively given the green light to research involving human-animal chimera embryos. Many researchers see the move to relax the rules as a welcome change, yet some are worried the revisions don’t take public concerns enough into consideration. [The Scientist] Editorial
