TOP STORY
Bronchioalveolar Morphogenesis of Human Bronchial Epithelial Cells Depending Upon Hepatocyte Growth Factor
The authors investigated morphogenic abilities of HBE135 human bronchial epithelial cells immortalized by E6/E7 oncogene in three-dimensional cultures. When HBE135 cells were cultured alone or co-cultured with endothelial cells, the cells formed spherical colonies without branching. [J Cell Mol Med] Abstract | Full Article

PUBLICATIONS (Ranked by impact factor of the journal)
IL-13 Augments Compressive Stress-Induced Tissue Factor Expression in Human Airway Epithelial Cells
Researchers investigated the role of IL-13, a type 2 cytokine, alone and in combination with compressive stress, which mimics asthmatic bronchoconstriction, on tissue factor (TF) expression and release of TF-positive extracellular vesicles from primary normal human bronchial epithelial cells. [Am J Respir Cell Mol Biol] Abstract

Posttranscriptional Silencing of the lncRNA MALAT1 by miR-217 Inhibits the Epithelial–Mesenchymal Transition via Enhancer of Zeste Homolog 2 in the Malignant Transformation of HBE Cells Induced by Cigarette Smoke Extract
The authors investigated the effects of an miRNA (miR-217) on levels of an lncRNA (MALAT1) and examined the role of these factors in the epithelial–mesenchymal transition induced by cigarette smoke extract in human bronchial epithelial (HBE) cells. [Toxicol Appl Pharmacol] Abstract

Continuous Activation of Nrf2 and Its Target Antioxidant Enzymes Leads to Arsenite-Induced Malignant Transformation of Human Bronchial Epithelial Cells
By establishing transformed human bronchial epithelial cells via chronic low-dose arsenite treatment, scientists showed that in acquiring this malignant phenotype, continuous low level of ROS and sustained enhancement of nuclear factor-erythroid-2 p45-related factor (Nrf2) and its target antioxidant enzymes levels were observed in the later-stage of arsenite-induced cell transformation. [Toxicol Appl Pharmacol] Abstract

Synergistic Proinflammatory Responses by IL-17A and Toll-Like Receptor 3 in Human Airway Epithelial Cells
Investigators demonstrated that IL-17A and polyI:C, the ligand of toll-like receptor 3, synergistically induced the expression of proinflammatory cytokines and chemokines, but not type I interferon in primary culture of normal human bronchial epithelial cells. [PLoS One] Full Article

Wedelolactone Protects Human Bronchial Epithelial Cell Injury against Cigarette Smoke Extract-Induced Oxidant Stress and Inflammation Responses through Nrf2 Pathway
Scientists investigated the effects of wedelolactone (WEL) on normal human bronchial epithelial (NHBE) cell injury induced by cigarette smoke extract (CSE) in vitro. They showed that the pretreatment WEL resulted in a significant protective effect on 10% CSE-induced cell death in NHBE cells. [Int Immunopharmacol] Abstract

LUNG CANCER

Ursolic Acid Exerts Anti-Cancer Activity by Suppressing Vaccinia-Related Kinase 1-Mediated Damage Repair in Lung Cancer Cells
Scientists found that ursolic acid (UA) inhibits the catalytic activity of vaccinia-related kinase 1 (VRK1) via direct binding to the catalytic domain of VRK1. UA weakens surveillance mechanisms by blocking 53BP1 foci formation induced by VRK1 in lung cancer cells, and possesses synergistic anti-cancer effects with DNA damaging drugs. [Sci Rep] Full Article

MiR-140-3p Suppressed Cell Growth and Invasion by Downregulating the Expression of ATP8A1 in Non-Small Cell Lung Cancer
Researchers identified MicroRNA (miR)-140-3p as a downregulated microRNA in most cancer tissues including lung cancer tissues, compared with their normal counterparts. MiR-140-3p was observed to perform its tumor suppressor function via its inhibition on cell growth, migration and invasion but its induction of cell apoptosis. [Tumour Biol] Abstract

The Iron Component of Particulate Matter Is Antiapoptotic: A Clue to the Development of Lung Cancer after Exposure to Atmospheric Pollutants?
The authors investigated transition metallic compounds, particularly iron, in order to decipher their underlying molecular mechanisms that prevent apoptosis. Human bronchial epithelial cells were exposed for four hours to different particulate matter samples with established antiapoptotic effect or not or to their metallic components before apoptosis induction by the calcium ionophore A23187 or Staurosporine. [Biochimie] Abstract

Placental Growth Factor Promotes Metastases of Non-Small Cell Lung Cancer through MMP9
The authors found that placental growth factor (PLGF) and matrix metalloproteinase 9 (MMP9) levels both significantly increased in the non-small cell lung cancer (NSCLC) specimens and were strongly correlated. Overexpression of PLGF in NSCLC cells increased the levels of MMP9 and cell invasiveness, while inhibition of PLGF in NSCLC cells decreased the levels of MMP9 and cell invasiveness.

SCIENCE NEWS
Two Positive Studies of Genentech’s Investigational Cancer Immunotherapy Atezolizumab in Specific Type of Lung Cancer Presented
Genentech announced positive results from two Phase II studies that evaluated the investigational cancer immunotherapy atezolizumab in people with advanced non-small cell lung cancer. [Press release from Genentech, Inc. discussing research presented at the European Cancer Congress (ECC 2015), Vienna] Press Release

GIOTRIF® (Afatinib) Demonstrates Superior Survival Compared to Tarceva® (Erlotinib) for Patients with Previously Treated Advanced Squamous Cell Carcinoma of the Lung, Independent of EGFR Mutation Status
Boehringer Ingelheim announced new data from the Phase III LUX-Lung 8 trial which further highlights the benefits of afatinib compared to erlotinib for the treatment of patients with previously treated advanced squamous cell carcinoma of the lung. [Press release from Boehringer Ingelheim GmbH discussing research presented at the European Cancer Congress (ECC 2015), Vienna] Press Release

Novel Tool Can Identify COPD
A novel approach for the identification of chronic obstructive pulmonary disease (COPD) has been developed. The findings could speed up current diagnosis times for the disease and uncover COPD before serious exacerbations and further loss of lung function have occurred. [Press release from the European Lung Foundation discussing research presented at the European Respiratory Society’s (ERS) International Congress, Amsterdam] Press Release

New Data Demonstrate Sustained Long-Term Efficacy of OFEV® on Slowing Disease Progression and Safety in Patients with IPF
An interim analysis of the INPULSIS®-ON extension trial has confirmed the efficacy and safety of OFEV® (nintedanib) previously observed in the INPULSIS® trials. The results confirm that OFEV® has a long-term effect on slowing disease progression and a manageable side effect profile in patients with idiopathic pulmonary fibrosis (IPF).

Severe Asthma Patients Less Responsive to Treatment
People with severe asthma, who are often described as ‘steroid-dependent’, are actually less likely to respond to the treatment they depend on, when compared to people with mild asthma. The study represents the first analysis of a cohort of patients from an unparalleled research project that will collect over three million samples from 300 children and 700 adults with severe and non-severe asthma, and without asthma.
