Aryl Hydrocarbon Receptor-Dependent Up-Regulation of the Heterodimeric Amino Acid Transporter LAT1 (SLC7A5)/CD98hc (SLC3A2) by Diesel Exhaust Particle Extract in Human Bronchial Epithelial Cells
Researchers analyzed the effects of diesel exhaust particle extract (DEPe) on LAT1/CD98hc expression in bronchial epithelial BEAS-2B cells. Exposure to DEPe up-regulated LAT1 and CD98hc mRNA levels in a concentration-dependent manner, with DEPe EC₅₀ values relevant to environmental situations. [Toxicol Appl Pharmacol] Abstract

Interferon Response of the Cystic Fibrosis Bronchial Epithelium to Major and Minor Group Rhinovirus Infection
Scientists assessed the antiviral response of cystic fibrosis and healthy bronchial epithelial cells to rhinovirus (RV) infection. They measured the levels of interferons (IFNs), pattern recognition receptors and IFN-stimulated genes upon infection with major and minor group RVs and poly(IC) stimulation.

Comparison of Innate Immune Responses towards Rhinovirus Infection of Primary Nasal and Bronchial Epithelial Cells
Researchers used primary paired nasal epithelial cell and bronchial epithelial cell cultures established from healthy subjects and compared the replication of rhinoviruses belonging to the major and minor group, and the cellular antiviral and proinflammatory cytokine responses towards these viruses.

Dasatinib Induces DNA Damage and Activates DNA Repair Pathways Leading to Senescence in Non-Small Cell Lung Cancer Cell Lines with Kinase-Inactivating BRAF Mutations
No canonical pathways explain dasatinib-induced senescence in kinase-inactivating BRAF mutations (^KIBRAF) non-small cell lung cancer (NSCLC). To investigate the underlying mechanism, scientists used two approaches: gene expression and reverse phase protein arrays. Both approaches showed that DNA repair pathways were differentially modulated between ^KIBRAF NSCLC cells and those with wild-type BRAF. [Oncotarget] Full Article

miR-181b Regulates Cisplatin Chemosensitivity and Metastasis by Targeting TGFβR1/Smad Signaling Pathway in NSCLC
The authors identified miR-181b and its mechanism in the chemosensitivity and metastasis of non-small cell lung cancer (NSCLC). They found that miR-181b expression levels were lower in A549/DDP cells compared with A549 cells. [Sci Rep] Full Article

Quercetin Inhibits Multiple Pathways Involved in Interleukin 6 Secretion from Human Lung Fibroblasts and Activity in Bronchial Epithelial Cell Transformation Induced by Benzo[a]Pyrene Diol Epoxide
The authors showed that benzo[a]pyrene diol epoxide-induced human bronchial epithelial cell transformation was enhanced by interleukin 6 in vitro. [Mol Carcinog] Abstract

CD44 Is Functionally Crucial for Driving Lung Cancer Stem Cells Metastasis through Wnt/β-Catenin-FoxM1-Twist Signaling
Scientists found that CD133⁺CD44⁺ cells which were derived from primary lung adenocarcinoma possessed cancer stem cell-like features. Furthermore, CD44 was demonstrated functionally crucial to drive metastatic potential of CD133⁺CD44⁺ lung cancer stem cell-like cells by in vitro and in vivo experiments. [Mol Carcinog] Abstract

Study of Bioreductive Anticancer Agent RH-1-Induced Signals Leading the Wild-Type p53-Bearing Lung Cancer A549 Cells to Apoptosis
Researchers investigated the involvement of different signaling molecules in cytotoxicity induced by RH-1 by using wild-type tumor suppressor p53-bearing non-small cell lung carcinoma A549 cells as a model. [Chem Res Toxicol] Abstract

NCCN Collaborates with Bristol-Myers Squibb to Study PD-L1 Expression and Test Interpretation in Lung Cancer
To improve the scientific knowledge concerning PD-L1 protein expression and help pathologists understand the diagnostic nuances associated with lung cancer treatment, the National Comprehensive Cancer Network^® (NCCN^®) Oncology Research Program and Bristol-Myers Squibb (BMS) are collaborating on the NCCN/BMS Thoracic Pathology Protocol Development Team.
