Asthma

ABSTRACT: Bronchial Epithelial Cells were isolated processed as described (Chu et al., 2002 and Zhao et al., 2011). The objective of the study was to identify differentially expressed genes between normal control (NC), mild-moderate asthmatic (MMA) and severe asthmatic (SA) patients. Isolated fresh bronchial epithelial cells were placed into trizol for further analysis.

Severe refractory asthma is associated with enhanced nitrative stress. To determine the mechanisms for high nitrative stress in human severe asthma (SA), 3-nitrotyrosine (3NT) was compared with Th1 and Th2 cytokine expression. In SA, high 3NT levels were associated with high interferon (IFN)-γ and low interleukin (IL)-13 expression, both of which have been reported to increase inducible nitric oxide synthase (iNOS) in human airway epithelial cells (HAECs). We found that IL-13 and IFN-γ synergist ...[more]

Project description:Bronchial Epithelial Cells were isolated processed as described (Chu et al., 2002 and Zhao et al., 2011). The objective of the study was to identify differentially expressed genes between normal control (NC), mild-moderate asmathic (notSA) and severe asthmatic (SA) patients. For demographics data, contact Dr.Sally Wenzel (wenzelse@upmc.edu) Bronchoscopy with endobronchial epithelial brushing was performed as previously described (Chu et al., 2002; Zhao et al., 2011). The bronchial brushings generally comprised >90% epithelial cells and were placed into Trizol for mRNA analysis. Total RNA extracted using Trizol according to the manufacturer's instructions. Cy3-CTP labeled RNA was prepared according to the standard Agilent protocol from 50ng total RNA. Labeled RNA was hybridized for 17 hr at 65 C on Agilent gene expression array. Arrays were washed according to the manufacturer's protocol. Slides were scanned immediately after washing on the Agilent DNA Microarray Scanner (G2505B) using one color scan setting for 4X44K array slides. Agilent Feature Extraction v10.7.3.1 was used with default parameters. Normalized signal intensity data are presented in the matrix. The data set was normalized by cyclic-LOESS with use of Bioconductor package as described previously (Wu W et. al. 2005)

DNA methylation in airway epithelial cells isloated by pronase and bronchial brush from individuals with and without asthma

Project description:The airway epithelium forms the interface between the inhaled environment and the lung. The airway epithelium is dysfunctional in asthma and epigenetic mechanisms are considered a contributory factor. We hypothesised that the DNA methylation profiles of cultured primary airway epithelial cells (AECs) would differ between cells isolated from individuals with asthma (n=17) versus those without asthma (n=16). AECs were isolated from patients by two different isolation techniques; pronase digestion (9 non-asthmatic, 8 asthmatic) and bronchial brushings (7 non-asthmatic and 9 asthmatic). DNA methylation was assessed using an Illumina Infinium HumanMethylation450 BeadChip array. DNA methylation of AECs clustered by isolation technique and linear regression identified 111 CpG sites differentially methylated between isolation techniques in healthy individuals. As a consequence, the effect of asthmatic status on DNA methylation was assessed within AEC samples isolated using the same technique. In pronase isolated AECs, 15 DNA regions were differentially methylated between asthmatics and non-asthmatics. In bronchial brush isolated AECs, 849 differentially methylated DNA regions were identified with no overlap to pronase regions. In conclusion, regardless of cell isolation technique, differential DNA methylation was associated with asthmatic status in AECs, providing further evidence for aberrant DNA methylation as a signature of epithelial dysfunction in asthma.

IL-13 stimulation of primary human bronchial epithelial cells in control individuals and patients with asthma.

Project description:We performed RNA sequencing of gene expression of differentiated primary human bronchial epithelial cells derived from control and asthmatic patients, stimulated with IL-13. The Type 2 Asthma mediator IL-13 was described to induce airway hyperresponsiveness, goblet cell metaplasia, mucus hypersecretion and airway remoddeling including impairment of epithelial barrier integrity. We investigated differential expression of SARS-CoV-2 related host gene expression as well as genes involved in N-linked glycosylation upon IL-13 in bronchial epithelial cells. Top IL-13 affected pathways included ion- and transmembrane transport, lipid metabolic processed and protein glycosylation.

A new approach for the study of lung smooth muscle phenotypes and its application in asthma

Project description:We developed a new method for the isolation of bronchial smooth muscle cells. This method is built upon a double fluorescent mouse SMA-GFP;NG2-DsRed and cell sorting. Using this method, we isolated bronchial smooth muscle cells from control and asthmatic C57BL/6J mice for gene profiling. Double fluorescent mice were induced to develop asthma using OVA. Bronchial smooth muscle cells were purified from asthmatic and control mice for mRNA array.

Alterations in bronchial airway microRNA expression for lung cancer detection

Project description:We have previously shown that gene-expression alterations in cytologically normal appearing bronchial epithelial cells can be used as a biomarker for lung cancer detection in smokers (Whitney et al., BMC Medical Genomics 2015; Silvestri et al., NEJM 2015). In this study, we have established that there are also alterations in bronchial microRNA-expression of smokers with lung cancer. Importantly, the performance of an existing bronchial mRNA-biomarker has been improved by integrating microRNA with mRNA expression.
