TOP STORYThe authors provide evidence that expression of the innate immune receptor Toll-like receptor 4 (TLR4) and the extracellular matrix glycosaminoglycan hyaluronan on type 2 alveolar epithelial cells (AEC2s) are important for AEC2 renewal, repair of lung injury and limiting the extent of fibrosis.

PUBLICATIONS(Ranked by impact factor of the journal)Researchers showed by analysis of conditional double mutants that the two T-box transcription factor genes Tbx2 and Tbx3 act together in the lung mesenchyme to maintain branching morphogenesis. [Dev Cell] Abstract | Graphical Abstract Researchers investigated the effects of HYDAMTIQ, a potent poly(ADP-ribose) polymerases-1 (PARP-1) inhibitor, in a murine model of lung fibrosis. They evaluated the role of PARP on transforming growth factor-β (TGF-β) expression and TGF-β/SMAD signaling pathway in lungs. [J Cell Mol Med] Full Article To determine if neutrophils influence alveolar epithelial repair in vivo, scientists developed a unilateral acid injury model that creates a severe yet survivable injury with features similar to acute respiratory distress syndrome. [Am J Physiol Lung Cell Mol Physiol] Abstract Molecular Impact of Electronic Cigarette Aerosol Exposure in Human Bronchial Epithelium Researchers sought to determine the molecular impact of electronic cigarette (ECIG) aerosol exposure in human bronchial epithelial cells. Gene expression profiling was conducted in primary human bronchial epithelial cells grown at Air Liquid Interface and exposed to one of four different ECIG aerosols, traditional cigarette smoke, or clean air. [Toxicol Sci] Abstract MUC18 Regulates Lung Rhinovirus Infection and Inflammation The in vivo role of MUC18 in the context of viral infections remains poorly understood. The goal of this study was to define the in vivo function of MUC18 during respiratory rhinovirus infection. [PLoS One] Full Article Protocadherin-1 Localization and Cell-Adhesion Function in Airway Epithelial Cells in Asthma The asthma gene PCDH1 encodes Protocadherin-1, a putative adhesion molecule of unknown function expressed in the airway epithelium. Scientists characterized the localization, differential expression, homotypic adhesion specificity and function of PCDH1 in airway epithelial cells in asthma. [PLoS One] Full Article LUNG CANCERResearchers investigated the collaborative effect of epithelial-to-mesenchymal transition and extracellular matrix in the metastatic process, which revealed increased collagen deposition in metastatic tumor tissues as a direct consequence of amplified collagen gene expression in ZEB1-activated mesenchymal lung cancer cells. [Oncogene] Abstract Investigators examined cytotoxic effect of GL-9 peptide on A459 cell line through studying the changes in TNF-α and CD44 gene expression and ROS production. Real-time PCR analysis showed that the treated A549 cells highly over expressed TNF-α, which was associated with a significant reduction of CD44 gene expression levels.

REVIEWSEGFR as a Pharmacological Target in EGFR-Mutant Non-Small-Cell Lung Cancer: Where Do We Stand Now? Ongoing clinical trials will provide evidence for optimal strategies for patients with epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer in the near future. Numerous new agents are specifically addressing resistance mechanisms; mature data are related to the T790M mutation and MET pathway activation. The authors provide a comprehensive review of new perspectives on how to optimize the management of this molecular disease.

POLICY NEWSDramatic Twists Could Upend Patent Battle over CRISPR Genome-Editing Method The 9-month-old patent battle over CRISPR, a novel genome-editing tool that could have immense commercial value, has taken two surprising twists. Last week, attorneys for the Broad Institute in Cambridge, Massachusetts, one of the research organizations vying for CRISPR rights, submitted motions that could let it win even if it loses. [Science Insider] Editorial Democratic Databases: Science on GitHub Scientists are turning to a software–development site to share data and code. [Nature Toolbox] Editorial UK Bioethicists Eye Designer Babies and CRISPR Cows From designer babies to engineered mosquitoes, advances in genome-editing technologies such as CRISPR–Cas9 have raised the possibility of tremendous scientific advances — and serious ethical concerns. [Nature News] Editorial Biologists Plan Scoring System for Antibodies Biomedical experts plan to create a scoring system that will help researchers choose reliable antibodies for their experiments. The only problems: figuring out how such a ranking would work — and getting manufacturers to adopt the standard. [Nature News] Editorial
