Multiple Cells-of-Origin of Mutant K-Ras-Induced Mouse Lung Adenocarcinoma
Scientists have used technology that enables us to conditionally target K-RasG12D expression in Surfactant Protein C+ alveolar type 2 cells and in Clara cell antigen 10+ Clara cells by use of cell-type-restricted recombinant Adeno-Cre viruses. [Proc Natl Acad Sci USA] Abstract | Full Article

PUBLICATIONS (Ranked by impact factor of the journal)
Nano Aerosol Chamber for In-Vitro Toxicity (NACIVT) Studies
The new NACIVT has been developed and fully characterized regarding its performance. As demonstrated in control experiments, there was no evidence for any adverse effects on human bronchial epithelial cells due to the exposure treatment in NACIVT. [Nanotoxicology] Abstract

Reactive Oxygen Species Contribute to Arsenic-Induced EZH2 Phosphorylation in Human Bronchial Epithelial Cells and Lung Cancer Cells
Previous studies suggested that arsenic is able to induce serine 21 phosphorylation of the EZH2 protein through activation of JNK, STAT3, and Akt signaling pathways in the bronchial epithelial cell line, BEAS-2B. Here, scientists further demonstrated that reactive oxygen species were involved in the arsenic-induced protein kinase activation that leads to EZH2 phosphorylation. [Toxicol Appl Pharmacol] Abstract

Activation of P2RY11 and ATP Release by LXA4 Restores the Airway Surface Liquid Layer and Epithelial Repair in Cystic Fibrosis
Researchers found that lipoxin A4 (LXA4) induced an apical ATP release from non-cystic fibrosis (CF) and CF airway epithelial cell lines and CF primary cultures. [Am J Respir Cell Mol Biol] Abstract

Direct and Indirect Air Particle Cytotoxicity in Human Alveolar Epithelial Cells
The effect of urban air particles from Buenos Aires and residual oil fly ash a surrogate of ambient air pollution, their soluble fractions and conditioned media on A549 lung epithelial cells was examined. [Toxicol In Vitro] Abstract

Cytotoxicity and Gene Expression Profiling of Polyhexamethylene Guanidine Hydrochloride in Human Alveolar A549 Cells
This study was done to elucidate the putative cytotoxic effect of polyhexamethylene guanidine (PHMG) and the PHMG-mediated altered gene expression in human alveolar epithelial A549 cells in vitro. [Toxicol In Vitro] Abstract


Serpins Promote Cancer Cell Survival and Vascular Co-Option in Brain Metastasis
Brain metastatic cells from lung cancer and breast cancer express high levels of anti-plasminogen activator serpins, including neuroserpin and serpin B2, to prevent plasmin generation and its metastasis-suppressive effects. [Cell]

RIP1 Maintains DNA Integrity and Cell Proliferation by Regulating PGC-1a-Mediated Mitochondrial Oxidative Phosphorylation and Glycolysis
Loss of receptor-interacting protein 1 (RIP1) in lung cancer cells suppressed peroxisome proliferator-activated receptor ? coactivator-1a (PGC-1a) expression, impairing mitochondrial oxidative phosphorylation and accelerating glycolysis, resulting in spontaneous DNA damage and p53-mediated cell proliferation inhibition. [Cell Death Differ] Abstract

Substrate Stiffness Regulates Filopodial Activities in Lung Cancer Cells
Researchers investigated the filopodial activities of human lung adenocarcinoma cells CL1-5 cultured on substrates of tunable stiffness using a novel platform. [PLoS One] Full Article

Cephalochromin Induces G0/G1 Cell Cycle Arrest and Apoptosis in A549 Human Non-Small-Cell Lung Cancer Cells by Inflicting Mitochondrial Disruption
The fungus-derived compound cephalochromin, isolated from the fermented broth of Cosmospora vilior YMJ89051501, shows growth-inhibitory and apoptotic activity against human lung cancer A549 cells in a concentration-dependent manner with an IC50 value of 2.8 µM at 48 hours. [J Nat Prod] Abstract

ARID1A Is Downregulated in Non-Small Cell Lung Cancer and Regulates Cell Proliferation and Apoptosis
Researchers found that AT-rich interactive domain 1A (ARID1A) expression was lower in lung cancer cell lines than normal bronchial epithelial HBE cell line. They also explored the involvement of ARID1A in biological behavior of lung cancer cell lines. [Tumor Biol] Abstract

First-Line Treatment of EGFR-Mutated Nonsmall Cell Lung Cancer: Critical Review on Study Methodology
The authors provide an overview of the evolution of the methodology used in eight Phase III trials investigating first-line targeted treatment of nonsmall cell lung cancer, identify key differences in methodology and reporting, and critically assess how these differences should be taken into account when interpreting the findings from such trials.
