TOP STORYThe Aryl Hydrocarbon Receptor Controls Cyclin O to Promote Epithelial Multiciliogenesis Epithelia function as barriers against environmental insults and express the transcription factor aryl hydrocarbon receptor (AhR). However, AhR function in these tissues is unknown. Scientists showed that AhR regulates multiciliogenesis in both murine airway epithelia and in Xenopus laevis epidermis.

PUBLICATIONS(Ranked by impact factor of the journal)Investigators determined if the frequency of radiation-induced transformation and cancer progression differed in three-dimensional compared to two-dimensional culture. [Sci Rep] Full Article Activation of the IL-13 receptor leads to signal transducer and activator of transcription 6 activation and subsequent induction of SAM pointed domain containing ETS transcription factor and chloride channel accessory 1, increasing secretion of the gel-forming mucin, MUC5AC. Researchers examined the effect of clarithromycin IL-13 signaling leading to production. [Antimicrob Agents Chemother] Abstract The authors investigated the effects of four essential oil components, trans-anethole, estragole, eugenol and isoeugenol, on the reduction in inflammation induced by particulate matter with an aerodynamic diameter below 2.5 μm, in human bronchial epithelial and human liver carcinoma cell lines. [Environmental Chemistry Letters] Full Article | Press Release Expansion of Human Airway Basal Stem Cells and Their Differentiation as 3D Tracheospheres Researchers report a protocol that dramatically increases the long-term expansion of primary human airway basal cells while maintaining their genomic stability using 3T3-J2 fibroblast coculture and ROCK inhibition. They also describe techniques for the differentiation and imaging of these expanded airway stem cells as three-dimensional tracheospheres containing basal, ciliated, and mucosecretory cells. [Methods Mol Biol] Abstract LUNG CANCERThe authors report that SerpinB2 is down-regulated in gefitinib-resistant (H292-Gef) cells compared to gefitinib-sensitive (H292) cells. The low SerpinB2 levels in H292-Gef cells were also associated with an enhancement in invasiveness and increase in the length of invadopodia-like structures in the cells. [Sci Rep] Full Article The authors investigated the possibility that Spalax p53 can activate autophagy. Using two complementary assays, they established that over-expression of the Spalax p53 in p53-null cells, potently induces autophagy. As Spalax is considered highly resistant to cancer, they further studied the relative contribution of autophagy on the outcome of H1299 cells, following transfection with Spalax p53. [Oncotarget] Full Article Scientists demonstrated that tumor necrosis factor-alpha (TNF-α) promoted lung cancer cell migration by up-regulation of matrix metalloproteinase-13. By gene silencing or kinase inhibition, they proposed that ataxia-telangiectasia mutated is a key up-stream regulator of TNF-α activated ERK/p38-NF-κB pathway. [Oncotarget] Full Article Researchers showed that overexpression of 14-3-3ζ was frequently detected in lung adenocarcinoma tissues and was significantly associated with lymph node metastasis and poor outcome. [Exp Cell Res] Abstract The authors examined the expression and clinical significance microRNA-383 in non-small cell lung cancer both in vitro and in vivo. [Biomed Pharmacother] Abstract | |

REVIEWSB Cells in Chronic Obstructive Pulmonary Disease: Moving to Center Stage The authors outline the evidence that links B cells and B cell-rich lymphoid follicles to the pathogenesis of COPD and the mechanisms involved. They also review the potential and limitations of B cells as therapeutic targets to slow the progression of human COPD.

POLICY NEWSSpecial: Obama’s Science Legacy The United States will elect a new president in November 2016. Nature is tracking the battle between Republican Donald Trump and Democrat Hillary Clinton — and analyzing how the election outcome could affect science. [Nature] Editorial New Leader of NIH’s Research Watchdog Faces Staff Revolt The Office of Research Integrity (ORI) in Rockville, Maryland, which guards against misconduct in biomedical research, usually attracts attention with its findings, not its internal workings. But two years ago, its director, David Wright, quit in a public huff, complaining that ORI was hobbled by a dysfunctional federal bureaucracy. Now, his successor is encountering her own rough waters, Science has learned. [ScienceInsider] Editorial Putin Appoints Church Historian as Science Minister Russian President Vladimir Putin has appointed a church historian as the country’s new science and education minister. The president announced that Olga Vasilyeva would succeed the current science minister, Dmitry Livanov, who will become presidential envoy on trade and economic relations with Ukraine, according to the Russian news agency Interfax. [Nature News] Editorial Obama’s Science Legacy: Betting Big on Biomedical Science Ambitious bids to map the brain and cure cancer have not boosted overall research funding. [Nature News] Editorial US Personalized-Medicine Industry Takes Hit from Supreme Court Rejections for US patents related to personalized medicine have spiked after recent Supreme Court decisions tightened the rules for such claims, an analysis of more than 39,000 patent applications reveals. [Nature News] Editorial Chemistry Group Throws Out Election Results after Fears of Vote Rigging Members of the Society of Biological Inorganic Chemistry are reacting with puzzlement and shock after learning that the results of a recent online leadership election have been thrown out because of voting irregularities—raising concerns over possible manipulation. [ScienceInsider] Editorial Updated: Companies Settle Gene Technology Patent Fight that Was Shrouded in Mystery Illumina Inc. and Oxford Nanopore Technologies have reached a settlement in this legal battle, according to a U.S. International Trade Commission document released last week. Oxford has agreed not to import or sell any product containing a pore with an amino acid sequence at least 68% similar to Mycobacterium smegmatis porin — the protein at the heart of Illumina’s infringement claim — and to destroy any inventory of such products.
