PUBLICATIONS (Ranked by impact factor of the journal)
Lipoxin A4 Prevents Tight Junction Disruption and Delays the Colonization of Cystic Fibrosis Bronchial Epithelial Cells by Pseudomonas aeruginosa
Investigators report a protective effect of lipoxin A4 against tight junction disruption caused by P. aeruginosa bacterial challenge together with a delaying action against bacterial invasion in cystic fibrosis (CF) airway epithelial cells from patients with CF and immortalized cell lines. [Am J Physiol Lung Cell Mol Physiol] Abstract

DJ-1 Modulates Nrf2-Mediated Protection in Human Primary Alveolar Type II Cells in Smokers
Scientists isolated primary alveolar type II cells from de-identified organ donors whose lungs were not suitable for transplantation. They analyzed the cell injury obtained from non-smokers, moderate smokers and heavy smokers. [Am J Respir Cell Mol Biol] Abstract

Cigarette Smoke Induces Human Airway Epithelial Senescence via GDF15 Production
Researchers analyzed expression of growth differentiation factor 15 (GDF15) and cellular senescence markers in airway epithelial cells of current smokers and nonsmokers. They then determined the role of GDF15 in cigarette smoke-induced airway epithelial senescence by using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated-9 genome editing approach. [Am J Respir Cell Mol Biol] Abstract

Alteration of Canonical and Non-Canonical WNT-Signaling by Crystalline Silica in Human Lung Epithelial Cells
Researchers utilized pathway analysis to designate connections between genes altered by silica in WNT-signaling networks. They confirmed microarray findings by QRT-PCR and demonstrated both activation of canonical and down-regulation of non-canonical signaling in immortalized and primary human bronchial epithelial cells. [Toxicol Appl Pharmacol] Abstract

Diminished COX-2/PGE2-Mediated Antiviral Response Due to Impaired NOX/MAPK Signaling in G6PD-Knockdown Lung Epithelial Cells
The role of glucose-6-phosphate dehydrogenase (G6PD) on the inflammatory response was determined in both scramble control and G6PD-knockdown A549 cells upon tumor necrosis factor-α stimulation. A decreased expression pattern of induced COX-2 and reduced production of downstream PGE2 occurred upon TNF-α stimulation in G6PD-kd A549 cells compared with scramble control A549 cells.

The Replication of Bangladeshi H9N2 Avian Influenza Viruses Carrying Genes from H7N3 in Mammals
Researchers characterized H9N2 influenza viruses carrying internal genes from highly pathogenic H7N3 viruses, which were isolated from chickens or quail from live-bird markets in Bangladesh between 2010 and 2013. They studied their replication kinetics in normal human bronchoepithelial cells and swine tracheal and lung explants, which exhibit many features of the mammalian airway epithelium and serve as a mammalian host model.

LUNG CANCER

Modulation of Membrane Properties of Lung Cancer Cells by Azurin Enhances the Sensitivity to EGFR-Targeted Therapy and Decreased β1 Integrin-Mediated Adhesion
Scientists demonstrated that azurin, an anticancer therapeutic protein originated from bacterial cells, controls the levels of integrin β1 and its appropriate membrane localization, impairing the intracellular signaling cascades downstream from these receptors and the invasiveness of cells. [Cell Cycle] Abstract

Oridonin Inhibits Gefitinib-Resistant Lung Cancer Cells by Suppressing EGFR/ERK/MMP-12 and CIP2A/Akt Signaling Pathways
Scientists investigated the antitumor activity and underlying mechanisms of oridonin. They demonstrated that this compound dose-dependently inhibited the proliferation, invasion, and migration of the gefitinib-resistant non-small cell lung cancer cells in vitro. [Int J Oncol] Abstract

HDAC6-Mediated EGFR Stabilization and Activation Restrict Cell Response to Sorafenib in Non-Small Cell Lung Cancer Cells
Overexpression of histone deacetylase 6 (HDAC6) confers resistance to sorafenib in non-small cell lung cancer (NSCLC) cells. Inhibition of HDAC6 with selective inhibitors synergizes with sorafenib to kill NSCLC cells via inhibition of sorafenib-mediated epidermal growth factor receptor (EGFR) pathway activation. [Med Oncol] Abstract

Activation of G-Protein-Coupled Estrogen Receptor Inhibits the Migration of Human Non-Small Cell Lung Cancer Cells Via IKK-β/NF-κB Signals
While there are limited data concerning the roles and effects of G-protein-coupled estrogen receptor (GPER) on the progression of non-small cell lung cancer (NSCLC), the authors revealed that the expression of GPER in NSCLC cells is obviously greater than that in lung fibroblast cell line MRC-5. [DNA Cell Biol] Abstract

REVIEWS
Oncogenic Roles and Drug Target of CXCR4/CXCL12 Axis in Lung Cancer and Cancer Stem Cell
The authors provide an evaluation of CXCL12/CXCR4 as the potential therapeutic target for lung cancers; they also focus on the synergistic effects of inhibition of CXCL12/CXCR4 axis and immunotherapy as well as chemotherapy. [Tumor Biol] Abstract
