TOP STORYIRE1α-XBP1s Pathway Promotes Prostate Cancer by Activating c-MYC Signaling The authors report that an IRE1α RNase-specific inhibitor, MKC8866, strongly inhibits prostate cancer (PCa) tumor growth as monotherapy in multiple preclinical models in mice and shows synergistic antitumor effects with current PCa drugs.

PUBLICATIONS(Ranked by impact factor of the journal)Researchers designed two antisense oligonucleotides (AONs) directed against cryptic splicing signals within the androgen receptor (AR) pre-mRNA. These two AONs, AON-ISE and AON-ESE, demonstrated high efficiency in silencing AR-V7 splicing without affecting full-length AR expression. [Oncogene] Full Article The authors synthesized a multifunctional liposomal system containing celecoxib and genistein drugs. The combinatorial effect of these drugs leads to the selectively induce the apoptosis of prostate cancer cells than normal fibroblast cells. [Cancer Lett] Abstract MicroRNA 141 Is Associated to Outcome and Aggressive Tumor Characteristics in Prostate Cancer Researchers explored the prognostic role of miR-141 and miR-145 in prostate cancer. Tumor epithelial and tumor stromal areas were evaluated separately and combined. In situ hybridization was used to evaluate the expression of the miRNAs. [Sci Rep] Full Article SP1 and RARα Regulate AGAP2 Expression in Cancer Investigators identified SP1 as a transcription factor bound to arf GAP with GTP-binding protein-like domain, ankyrin repeat and PH domain 2 (AGAP2) promoter and required for AGAP2 expression in two different types of cancer cells. [Sci Rep] Full Article Significant biological effects were detected in PC-3 and DU-145 cell lines where curcuminoids extracted with innovative techniques and effectively loaded by polymeric nanobubbles were able to inhibit adhesion and migration, to promote cell apoptosis and to affect cell viability and colony-forming capacity in a dose-dependent manner. [Nanotechnology] Abstract Downregulated NOX4 Underlies a Novel Inhibitory Role of MicroRNA‐137 in Prostate Cancer Scientists explored the effect of miR‐137 in prostate cancer via regulating NADPH oxidase 4 (NOX4). Initially, microarray analysis was performed to obtain prostate cancer‐related differentially expressed genes and miRs that regulated NOX4, followed by detecting the expression of miR‐137 and NOX4 and its target relationship. [J Cell Biochem] Abstract Antitumor Effect of a Dual Cancer-Specific Oncolytic Adenovirus on Prostate Cancer PC-3 Cells Crystal violet staining and MTS results showed that the proliferation ability of PC-3-luc cells decreased significantly. Hoechst, JC-1, and Annexin V experiments demonstrated that Ad-VT mainly induced apoptosis to inhibit PC-3-luc cell proliferation. [Urol Oncol] Abstract Scientists developed and characterized a human 3D prostate organoid co-culture model that incorporates prostate stroma. Primary prostate stromal cells increased organoid formation and directed organoid morphology into a branched acini-structure similar to what is observed in vivo.

REVIEWSThe authors review prostate cancer (PCa) preclinical model cell lines and their sublines, patient-derived xenografts, and patient-derived organoid and spheroid models. These PCa models will be applied to the development of new strategies for cancer precision medicine.

INDUSTRY NEWSSTEMCELL Technologies has released mTeSR™ Plus, an enhanced version of mTeSR™1, the most widely published feeder-free human pluripotent stem cell maintenance medium. The new medium has undergone successful beta testing with several members of the Stem Cell COREdinates group and has completed rigorous in-house validation testing. [STEMCELL Technologies, Inc.] Press Release Trovagene, Inc. announced the issuance of a new patent, entitled Combination Therapies and Methods of Use Thereof for Treating Cancer, by the U.S. Patent and Trademark Office. [Trovagene, Inc.] Press Release NCI Awards $1.7 Million to UIC for Research on Southeast Asian Fruit For generations, traditional healers in Southeast Asia have used the mangosteen fruit to treat skin infections, wounds, dysentery and urinary tract infections. A new $1.7 million grant from the National Cancer Institute will enable researchers at the University of Illinois at Chicago (UIC) to study the fruit and its potential as a treatment for prostate cancer.

POLICY NEWSScientists Relieved but Wary as US Shutdown Nears End The US government is poised to re-open after a historic 34-day shutdown that has paralyzed the National Science Foundation, NASA and other key science agencies. [Nature News] Editorial Brazil’s New President Has Scientists Worried. Here’s Why Brazil has long been a frontrunner in climate change policy and environmental diplomacy. The international conventions on climate change and biological diversity, for example, were born during the historic United Nations Earth Summit in Rio de Janeiro in 1992, and Brazil played a key role in crafting and implementing both agreements. That legacy is now at risk. [ScienceInsider] Editorial Number of EU Research Students in Britain Drops from Pre-Referendum High The number of postgraduate researchers at UK universities who come from other European Union (EU) countries has fallen since the Brexit referendum in June 2016. [Nature News] Editorial CRISPR-Baby Scientist Fired by University The scientist who announced last year that he had produced the world’s first gene-edited babies has been fired by his university.
