Assessment of the Oxidative Potential of Nanoparticles by the Cytochrome C Assay: Assay Improvement and Development of a High-Throughput Method to Predict the Toxicity of Nanoparticles
Researchers studied the effect of insoluble nanoparticles on the human bronchial epithelial cell line NCI-H292 by measuring the cytotoxicity, pro-inflammatory response and antioxidant defense induction. [Arch Toxicol] Abstract

Knockout Mice Reveal a Major Role for Alveolar Epithelial Type I Cells in Alveolar Fluid Clearance
The specific contribution of the β1 subunit and relative contributions of alveolar epithelial type II (AT2) vs type I (AT1) cells to alveolar fluid clearance were investigated using two cell type-specific mouse knockout lines in which β1 subunit was knocked out in either AT1 cells or in both AT1 and AT2 cells. [Am J Respir Cell Mol Biol] Abstract

Epithelial Cell-Derived Secreted and Transmembrane 1a (Sectm1a) Signals to Activated Neutrophils During Pneumococcal Pneumonia
Researchers aimed to identify unique contributions of epithelial cells during lung infection. In order to differentiate genes induced selectively in epithelial cells during pneumonia, they compared genome-wide expression profiles from three sorted cell populations: epithelial cells from uninfected mouse lungs, epithelial cells from mouse lungs with pneumococcal pneumonia, and non-epithelial cells from those same infected lungs. [Am J Respir Cell Mol Biol] Abstract

The South Pacific Epidemic Strain of Zika Virus Replicates Efficiently in Human Epithelial A549 Cells Leading to IFN-β Production and Apoptosis Induction
The authors evaluated the susceptibility of human lung epithelial A549 cells to South Pacific epidemic strain of Zika virus (ZIKV) isolated in 2013. They showed that ZIKV growth in A549 cells is greatly efficient. [Virology] Full Article

The Novel H7N9 Influenza A Virus NS1 Induces p53-Mediated Apoptosis of A549 Cells
Apoptotic effect and features of H7N9/NS1 in the human A549 alveolar basal epithelial cell line were examined by caspase 3/7 activity assay and western blotting of apoptotic associated proteins. Effects of H7N9/NS1on mitochondrial membrane potential were investigated by flow cytometry. [Cell Physiol Biochem] Full Article


Arsenite and Cadmium Activate MAPK/ERK via Membrane Estrogen Receptors and G-Protein Coupled Estrogen Receptor Signaling in Human Lung Adenocarcinoma Cells
Investigators examined the effect of cadmium chloride (CdCl2) and sodium arsenite (NaAsO2) on the proliferation of human lung adenocarcinoma cell lines. Results demonstrated that both CdCl2 and NaAsO2 stimulated cell proliferation at environmentally relevant nM concentrations in a similar manner to 17β-estradiol in H1793, H2073, and H1944 cells, but not in H1792 or H1299 cells. [Toxicol Sci] Abstract

Uncoordinated 51-Like Kinase 2 Signaling Pathway Regulates Epithelial-Mesenchymal Transition in A549 Lung Cancer Cells
Scientists provide evidence that uncoordinated 51-like kinase 2 regulates epithelial-mesenchymal transition (EMT). Induction of autophagy by inhibition of mammalian target of rapamycin complex 1 (mTORC1) or by disruption of mTORC1 by silencing raptor significantly enhanced EMT, however, disruption of mTORC2 by silencing rictor had no effect. [FEBS Lett] Abstract

MicroRNA-124 Functions as a Tumor Suppressor by Regulating CDH2 and Epithelial-Mesenchymal Transition in Non-Small Cell Lung Cancer
Significantly decreased expression of microRNA-124 (miR-124) was found in non-small cell lung cancer (NSCLC) specimens and cell lines. Overexpression of miR-124 apparently suppressed the proliferation and invasion of NSCLC cell lines in vitro. [Cell Physiol Biochem] Full Article

MiR-1244 Sensitizes the Resistance of Non-Small Cell Lung Cancer A549 Cell to Cisplatin
Scientists investigated the function of miRNAs in cisplatin (DDP)-resistant non-small cell lung cancer A549 cell. Both miR-589 and miR-1244 were significantly down-regulated in A549/DDP cell compared to the parental A549, while the expression of miR-182 and miR-224 were increased in A549/DDP cell.

Perifosine and ABT-737 Synergistically Inhibit Lung Cancer Cells In Vitro and In Vivo
The authors explored the potential synergism between the novel Bcl-2 antagonist ABT-737 and the AKT inhibitor perifosine in lung cancer cells. They showed that perifosine and ABT-737 synergistically induced growth inhibition and apoptosis in both established and patient-derived lung cancer cells. [Biochem Biophys Res Commun] Abstract

Cells and Culture Systems Used to Model the Small Airway Epithelium
The authors focus on the commonly used small airway epithelial cells, their 2-dimensional and 3-dimensional culture techniques, and their comparative phenotype when cultured under these systems. [Lung] Abstract
