TOP STORY

Integrin α11β1 Regulates Cancer Stromal Stiffness and Promotes Tumorigenicity and Metastasis in Non-Small Cell Lung Cancer
The growth of A549 lung adenocarcinoma cells and two patient-derived non-small cell lung carcinoma xenografts in integrin α11 knockout mice was significantly impeded, as compared with wild-type severe combined immune deficient mice. [Oncogene] Full Article

PUBLICATIONS (Ranked by impact factor of the journal)

Burkholderia pseudomallei Survival in Lung Epithelial Cells Benefits from miRNA-Mediated Suppression of ATG10
Based on microarray screening, scientists found that ATG10 was downregulated following B. pseudomallei infection in A549 human lung epithelial cells. Forced expression of ATG10 accelerated the elimination of intracellular B. pseudomallei by enhancing the process of autophagy. [Autophagy] Abstract

Mono- and Cocultures of Bronchial and Alveolar Epithelial Cells Respond Differently to Proinflammatory Stimuli and Their Modulation by Salbutamol and Budesonide
Researchers investigated the changes in transport and effectiveness of salbutamol sulfate and budesonide following stimulation with transforming growth factor-β in mono- and coculture models of bronchial and alveolar epithelium. [Mol Pharm] Abstract | Graphical Abstract

Junctional Abnormalities in Human Airway Epithelial Cells Expressing delF508 CFTR
The authors examined changes to CFTR function, tight junctions, and gap junctions in NuLi-1 and CuFi-5. Cells were studied at air-liquid interface and compared to primary human bronchial epithelial cells. [Am J Physiol Lung Cell Mol Physiol] Abstract

Modulation of Cytokines and Chemokines Expression by NAC in Cadmium Chloride Treated Human Lung Cells
Researchers studied the immunomodulatory effect of a well-known antioxidant, N-acetylcysteine (NAC) on cadmium chloride treated human lung A549 cells through human cytokine array 6. [Environ Toxicol] Abstract

LUNG CANCER

RhoB Loss Induces Rac1-Dependent Mesenchymal Cell Invasion in Lung Cells through PP2A Inhibition
Scientists identified the small GTPase RhoB as a key regulator of bronchial cell morphology in a three-dimensional (3D) matrix. RhoB loss, which is frequently observed during lung cancer progression, induced an epithelial-mesenchymal transition characterized by an increased proportion of invasive elongated cells in 3D. [Oncogene] Abstract

Neuropilin 1 Expression Correlates with the Radio-Resistance of Human Non-Small-Cell Lung Cancer Cells
Investigators determined the correlation between over-expression of the neuropilin 1 gene and growth, survival, and radio-sensitivity of non-small cell lung carcinoma cells. [J Cell Mol Med] Full Article

The Topoisomerase 1 Inhibitor Austrobailignan-1 Isolated from Koelreuteria henryi Induces a G2/M-Phase Arrest and Cell Death Independently of p53 in Non-Small Cell Lung Cancer Cells
Researchers showed that austrobailignan-1 inhibited cell growth of human non-small cell lung cancer A549 and H1299 cell lines in both dose- and time-dependent manners, the IC₅₀ value of austrobailignan-1 were 41 and 22 nM, respectively. [PLoS One] Full Article

MicroRNA-410 Promotes Cell Proliferation by Targeting BRD7 in Non-Small Cell Lung Cancer
The authors showed that the expression of miR-410 was up-regulated in both human NSCLC tissues and cells. Overexpression of miR-410 promoted cell proliferation, migration, and invasion of NSCLC. [FEBS Lett] Abstract

REVIEWS

Genomic Alterations in Lung Adenocarcinoma
Data clearly suggest that lung adenocarcinoma is associated with distinct genomic alterations compared with other lung cancer subtypes, and highlight the widespread molecular heterogeneity that underlies the disease. In this review, the authors discuss some of the key findings from genomic studies of lung adenocarcinoma. [Lancet Oncol] Abstract
