Analysis of the TGFβ-Induced Program in Primary Airway Epithelial Cells Shows Essential Role of NF-κB/RelA Signaling Network in Type II Epithelial Mesenchymal Transition
Researchers applied next generation sequencing in primary human airway epithelial cells to understand the gene program controlling type II epithelial mesenchymal transition and how cytokine-induced inflammation modifies it. [BMC Genomics] Full Article

The Kinetic Response of the Proteome in A549 Cells Exposed to ZnSO₄ Stress
The authors investigated the time-dependent differential expression of the proteome in A549 cells after administered with ZnSO₄ for both 9 and 24 hours using 2DE. 123 differentially expressed protein spots were detected, most of which were up-regulated by Zn²⁺ treatment. [PLoS One] Full Article

Maresin1 Inhibits Epithelial-to-Mesenchymal Transition In Vitro and Attenuates Bleomycin Induced Lung Fibrosis In Vivo
Scientists investigated whether MaR1, a kind of pro-resolving lipid mediators, could inhibit TGF-β1 induced epithelial to mesenchymal transition in vitro and lung fibrosis in vivo. In in vitro studies, mouse type II alveolar epithelial cells were treated with different doses of MaR1 for 30 minutes and were exposed to TGF-β1 for 48 hours. [Shock] Abstract

Cigarette Smoke Affects IL-17A, IL-17F and IL-17 Receptor Expression in the Lung Tissue: Ex Vivo and In Vitro Studies
In vitro, human epithelial cell line 16HBE and A549 as well as PBMC from normal donors were stimulated with cigarette smoke extract to evaluate the IL-17A, IL-17F and IL-17R expression by flow cytometry. [Cytokine] Abstract

EGCG Reverses Human Neutrophil Elastase-Induced Migration in A549 Cells by Directly Binding to HNE and By Regulating α1-AT
Investigators demonstrated a novel mechanism by which EGCG reverses the neutrophil elastase-induced migration of A549 cells. [Sci Rep] Full Article

Synergistic Effects between mTOR Complex 1/2 and Glycolysis Inhibitors in Non-Small-Cell Lung Carcinoma Cells
By employing automated spectrophotometry, scientists found the level of glucose uptake was decreased in non-small-cell lung carcinoma (NSCLC) A549, PC-9 and SK-MES-1 cells treated with rapamycin or siRNA against Raptor, indicating that the inhibition of mammalian target of rapamycin (mTOR) complex 1 attenuated glycolytic metabolism in NSCLC cells.

Resveratrol Analogue 3,4,4′-Trihydroxy-Trans-Stilbene Induces Apoptosis and Autophagy in Human Non-Small-Cell Lung Cancer Cells In Vitro
Treatment with 3,4,4′-trihydroxy-trans-stilbene concentration-dependently inhibited cell viability. It did not cause cell necrosis, but induced apoptosis accompanied by up-regulation of cleavaged PARP, caspase3/9 and Bax, and by down-regulation of Bcl-2 and surviving. [Acta Pharmacol Sin] Abstract

7-Epiclusianone, a Benzophenone Extracted from Garcinia brasiliensis (Clusiaceae), Induces Cell Cycle Arrest in G1/S Transition in A549 Cells
The authors investigated the mechanisms involved with antiproliferative activity of 7-epiclusianone in A549 cells. They showed that 7-epiclusianone reduced the viability of A549 cells in a concentration-dependent manner. [Molecules] Abstract | Download Full Article

Primary Airway Epithelial Cell Culture and Asthma in Children–Lessons Learnt and Yet to Come
The authors first explore how the challenges of studying nasal and bronchial airway epithelial cells (AECs) in children have been addressed and then summarize the results of studies of primary AEC function in children with and without asthma. [Pediatr Pulmonol] Abstract
