Regional heterogeneity in response of airway epithelial cells to cigarette smoke

ABSTRACT: To investigate the biochemical and genetic alterations that occur in response to cigarette smoke exposure among airway epithelial cells from different sites in the lungs, we performed microarray-based analysis using small airway epithelial cells (SAEC) and normal human bronchial epithelial cells (NHBE) following 24 h of cigarette smoke extract (CSE). In microarray-based analysis, the small airway showed higher susceptibility to CS compared to the large airway, such as enhanced expression of inflammatory-related pathways including the TNF signaling pathway. Among the TNF-related genes, PTGS2, also known as COX-2, showed the greatest difference in expression levels, with higher CSE-induced increments of both mRNA and protein expression in SAEC compared to NHBE.

Cigarette Smoke Activates NOTCH3 to Promote Goblet Cell Differentiation in Human Airway Epithelial Cells

Project description:Chronic obstructive pulmonary disease (COPD) is the 3rd leading cause of death in the United States and is caused primarily by cigarette smoking. Increased numbers of mucus-producing secretory (“goblet”) cells defined as goblet cell metaplasia or hyperplasia (GCMH), contributes significantly to COPD pathophysiology. The objective of this study was to determine whether NOTCH signaling regulates goblet cell differentiation in response to cigarette smoke. To this end, primary human bronchial epithelial cells (HBECs) from nonsmokers and COPD smokers were differentiated in vitro on air-liquid interface and exposed to cigarette smoke extract (CSE) for 7 days. NOTCH signaling activity was modulated using (1) the NOTCH/γ-secretase inhibitor Dibenzazepine (DBZ), (2) lentiviral over-expression of the NOTCH3-intracellular domain (NICD3) or (3) NOTCH3-specific siRNA. Cell differentiation and response to CSE were evaluated by qPCR, Western blotting, immunostaining and RNA-Seq. Our data demonstrate that CSE exposure of nonsmoker airway epithelium induced goblet cell differentiation characteristic of GCMH. Treatment with DBZ suppressed CSE-dependent induction of goblet cell differentiation. Furthermore, CSE induced NOTCH3 activation, as revealed by increased NOTCH3 nuclear localization and elevated NICD3 protein levels. Over-expression of NICD3 increased expression of the goblet cell associated genes SPDEF and MUC5AC, whereas NOTCH3 knockdown suppressed CSE-mediated induction of SPDEF and MUC5AC. Finally, CSE exposure of COPD airway epithelium induced goblet cell differentiation in a NOTCH3-dependent manner. These results identify NOTCH3 activation as one of the important mechanisms by which cigarette smoke induces goblet cell differentiation, thus providing a potential strategy to control GCMH-related pathologies in smokers and patients with COPD.

Time course of NHBE cells exposed to whole cigarette smoke

Project description:Gene expression patterns were assessed in normal human bronchial epithelial (NHBE) cells exposed to cigarette smoke from a reference cigarette (2R4F, University of Kentucky) and a typical American brand of "light" cigarettes ("Lights") in order to develop a better understanding of the genomic impact of tobacco exposure, which can ultimately define biomarkers that discriminate tobacco-related effects and outcomes in a clinical setting. NHBE cells were treated with whole cigarette smoke for 15 minutes and alterations to the transcriptome assessed at 2, 4, 8 and 24 hours post-exposure using high-density oligonucleotide microarrays. Keywords: time course, cigarette smoke exposure

Human airway epithelial responses to rhinovirus infection and cigarette smoke extract alone and in combination

Project description:This study was performed to test the hypothesis that cigarette smoke extract would alter the responses of primary cultures of human bronchial epithelial cells to infection with purified human rhinovirus 16. The data show marked alterations in rhinovirus-induced expression profiles of a number of genes in the presence of cigarette smoke extract (CSE). Cultured epithelial cells from each of 4 donors were exposed to medium alone, rhinovirus 16 (RV16) alone, CSE alone, or RV16 in the presence of CSE. After a 24 h incubation gene expression was assessed.

Human alveolar epithelial cells (A549) exposed to cigarette smoke extract

Project description:Human alveolar epithelial cells were exposed to cigarette smoke extract (CSE) for 1, 3 and 5 weeks at 1%, 5% and 10%, and gene expression was evaluated by complete transcriptome microarrays. In this study we explored the effect of cigarette smoke on the gene expression profile. Human alveolar epithelial cells stimulated with three different concentractions of CSE (1%, 5% and 10%) and for 1, 3 and 5 weeks were used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Analysis of 2 cultured normal lung cell lines, Normal Human Bronchial Epithelial (NHBE) and Human Small Airway Epithelial (SAEC) cells (Lonza, Walkersville, MD), following treatment with 5-aza-dC to induce DNA demethylation. These results provide insight into the role of epigenetic alterations, specifically demethylation, in differential gene expression in various lung neoplasms.

The Effect of Repeated Whole Cigarette Smoke Challenge on Human Air-Liquid Interface Lung Epithelial Cultures

Project description:Airway epithelial cells are the first cells of the lungs to be exposed to the toxic agents contained within cigarette smoke. Accordingly, the response of these cells to this challenge is of considerable interest in the context of diseases in which cigarette smoke is a major aetiological factor. We used Affymetrix microarrays to study the effects of repeated cigarette smoke challenge on three-dimensional human lung airway epithelial cultures.
