Team Pinpoints Developmental Gene that Regulates Repair and Regeneration in Adult Lungs
The whimsically named sonic hedgehog gene, best known for controlling embryonic development, also maintains the normal physiological state and repair process of an adult healthy lung, if damaged, according to new research.

Video Protocol: Mucociliary Differentiation of Primary Bronchial Epithelial Cells
PUBLICATIONS (Ranked by impact factor of the journal)
KIF7 Controls the Proliferation of Cells of the Respiratory Airway through Distinct Microtubule Dependent Mechanisms
Researchers showed that kinesin family member 7 (Kif7) is required for coordination of the cell cycle, and inactivation of this gene leads to increased cell proliferation in vivo and in vitro. [PLoS Genet] Full Article

High Mobility Group Box 1 (HMGB1) Promotes Extracellular Matrix Synthesis and Wound Repair in Human Bronchial Epithelial Cells
As epithelial cell responses are fundamental drivers of asthma, including abnormal repair-restitution linked to changes in extracellular matrix (ECM) synthesis, scientists tested the hypothesis that HMGB1 promotes bronchial epithelial cell wound repair via toll-like receptor 4 and/or receptor for advanced glycated end products signaling that regulates ECM and integrin protein abundance. [Am J Physiol Lung Cell Mol Physiol] Abstract

BARD1 Mediates TGF-β Signaling in Pulmonary Fibrosis
The authors investigated BARD1 expression as a function of TGF-β in cultured cells, in mice with experimentally induced lung fibrosis, and in lung biopsies from pulmonary fibrosis patients. Full length BARD1 and BARD1β were upregulated in response to TGF-β in epithelial cells and fibroblasts in vitro and in vivo. [Respir Res] Full Article

Correlation of Organic Cation/Carnitine Transporter 1 and Multidrug Resistance-Associated Protein 1 Transport Activities with Protein Expression Levels in Primary Cultured Human Tracheal, Bronchial, and Alveolar Epithelial Cells
Investigators evaluated whether differences in organic cation/carnitine transporter 1 and multidrug resistance-associated protein 1 protein expression govern the respective transport activity in primary cultured human lung cells. [J Pharm Sci] Abstract


MicroRNA-92a Promotes Growth, Metastasis, and Chemoresistance in Non-Small Cell Lung Cancer Cells by Targeting PTEN
Function assays demonstrated that upregulation of microRNA-92a (miR-92a) in non-small cell lung cancer (NSCLC) cells promoted cell proliferation, migration, and invasion, decreased apoptosis and caspase-3 activity, and enhanced chemoresistance of NSCLC cells, whereas downregulation of miR-92a showed the opposite effects. [Tumour Biol] Abstract

Increased Insulin-Like Growth Factor 1 Receptor (IGF1R) Expression in Small Cell Lung Cancer and the Effect of Inhibition of IGF1R Expression by RNAi on Growth of Human Small Cell Lung Cancer NCI-H446 Cell
The expression and clinical significance of IGF1R were investigated in serum and lung cancer tissues from small cell lung cancinoma. Researchers also compared the effect of IGF1R up-regulation and IGF1R inhibition on viability and apoptosis of NCI-H446 cells. [Growth Factors] Abstract

Functional Analyses of ATM, ATR and Fanconi Anemia Proteins in Lung Carcinoma: ATM, ATR and FA in Lung Carcinoma
Scientists undertook functional analyses of ATM, ATR, Chk1 and Fanconi anemia (FA) proteins in lung cancer cell lines. No defects in ATM, ATR or Chk1 kinase activation, or FANCD2 monoubiquitination were identified in the lung cancer cell lines examined, including Calu6, and major alterations in these pathways were not identified in the cancer genome atlas database.

Contrasting Effects of the Cytotoxic Anticancer Drug Gemcitabine and the EGFR Tyrosine Kinase Inhibitor Gefitinib on NK Cell-Mediated Cytotoxicity via Regulation of NKG2D Ligand in Non-Small-Cell Lung Cancer Cells
The authors examined the effect of the cytotoxic drug Gemcitabine and the EGFR tyrosine kinase inhibitor Gefitinib on the expression of NK group 2 member D (NKG2D) ligands as well as the sensitivity of non-small-cell lung cancer cells to the NK-mediated lysis. [PLoS One] Full Article

Post-Translational Modification of E-Cadherin by Core-Fucosylation Regulates Src Activation and Induces Epithelial-Mesenchymal Transition-Like Process in Lung Cancer Cells
Through gain and loss of fucosylation experiments in the giant lung carcinoma cell lines 95C and 95D, the authors revealed that E-cadherin core-fucosylation in 95C cells overexpressing α-1, 6-fucosyltransferase (Fut8) inhibited Fut8-95C cell migration, whereas knockdown of Fut8 in 95D cells enhanced migration of siFut8-95D cells. [Glycobiology] Abstract

Phosphodiesterase 4 Inhibitors for the Treatment of Chronic Obstructive Pulmonary Disease: A Review of Current and Developing Drugs
The authors review the current role of phosphodiesterase-4 inhibitor (PDE4I) in chronic obstructive pulmonary disease treatment emphasizing roflumilast’s clinical efficacy and adverse effects. They also review developing PDE4Is in early clinical trials and in preclinical studies. [Expert Opin Investig Drugs] Abstract

AstraZeneca Presents Respiratory Syncytial Virus (RSV) Study
In collaboration with physicians at 43 US hospitals, AstraZeneca presented results from an ongoing observational study, SENTINEL1. SENTINEL1 was designed to characterize RSV-confirmed hospitalizations among US preterm infants born at 29-35 weeks gestation who did not receive immunoprophylaxis during the 2014-2015 RSV season.
