(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease typified by not fully reversible and often progressive airflow obstruction, along with persistent respiratory symptoms. This gap is due to lack of animal models that more closely mimic human COPD are needed to bridge translational gaps. Commonly used mice model produces primarily emphysematous disease and do not develop features pathognomonic for chronic bronchitis. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD), the fourth leading cause of death globally, is influenced by both cigarette smoking and genetic determinants. We have previously identified iron-responsive element binding protein 2 (IRP2) as a candidate COPD susceptibility gene based on genetic association studies, with IRP2 increased in the lungs of COPD patients. Here we demonstrate that mice deficient in IRP2 are protected from cigarette smoke (CS)-induced COPD. more...

(Submitter supplied) Whole lung tissue transcriptomic profiling studies in chronic obstructive pulmonary disease (COPD) have led to the identification of several genes associated with the severity of airflow limitation and/or the presence of emphysema, however, the cell types driving these gene expression signatures remain unidentified. T-distributed stochastic neighbor embedding and clustering of scRNA seq data revealed a total of 17 distinct populations. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) has the highest increased risk due to household air pollution arising from biomass fuel burning. However, knowledge on COPD patho-mechanisms is mainly limited to tobacco smoke exposure. In this study, a repeated direct wood smoke (WS) exposure was performed using normal- (bro-ALI) and chronic bronchitis-like bronchial (bro-ALI-CB), and alveolar (alv-ALI) lung mucosa models at air-liquid interface (ALI) to assess broad toxicological end points. more...

(Submitter supplied) The goal of this study is to use newly designed ferret Agilent arrays to compare transcriptome profiles between wild type, CF3959(-/-) and CF3959(+/-) ferrets. Lung and trachea tissues from newborn and 15 day-old ferrets were RNA-extracted and subsequently analyzed by microarray.

(Submitter supplied) The domestic ferret (Mustela putorius furo) has been used as animal model for decades, largely because its susceptibility to infection with a large number of pathogens such as influenza virus, SARS Corona virus and Canine distemper virus. Despite its importance for biomedical research, little is known about the genome of the M. Furo. The number of reagents for molecular and immunological analysis is thus restricted. more...

(Submitter supplied) Multiple gene expression studies have been performed separately in peripheral blood, lung, and airway tissues to study COPD. We performed RNA-sequencing gene expression profiling of large-airway epithelium, alveolar macrophage and peripheral blood samples from the same set of COPD cases and controls from the COPDGene study who underwent bronchoscopy at a single center. Using statistical and gene set enrichment approaches, we sought to improve the understanding of COPD by studying gene sets and pathways across these tissues, beyond the individual genomic determinants.

(Submitter supplied) Our data demonstrates enrichment of the GO term extracellular region among the decreased lung transcripts of JF1 throughout the process of lung development and maturation in consistent to the altered elastin to collagen ratio. Our microarray data showed increased ~4 fold increased elastin transcripts in JF1 lungs at P70. Specific CL‐saline/air ratio in JF1 mice compared to C3H (JF1-male: 2.68±01.10 versus C3H-male: 2.15±0.42, p<0.05; JF1-female: 3.22±0.88 versus C3H-female: 2.27±0.23, p<0.05) suggests that surface tension contributes more than the elastic recoiling properties of lung in determining the lung compliance as assessed by air filling. more...

(Submitter supplied) We analyzed gene expression profiling of lung tissue to define molecular pathway of COPD using recent RNA sequencing technology.Lung tissue was obtained from 98 COPD subjects and 91 subjects with normal spirometry. RNA isolated from these samples was processed with RNA-seq using HiSeq 2000. Gene expression measurements were calculated using Cufflinks software. Differentially expressed genes and isoforms were chosen using t-test. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of morbidity and mortality in the world and is predicted to be the third leading cause of death. It is characterized by chronic airway inflammation, lung destruction and remodeling, resulting in irreversible airflow obstruction. We utilized single cell RNA-sequencing (scRNA-Seq) to identify ferroptotic differences and associated biological processes involved in the pathogenesis of COPD. more...

(Submitter supplied) Although cigarette smoke (CS) is the primary risk factor for COPD, the underlying molecular mechanisms for the significant variability in developing COPD in response to CS are incompletely understood. We performed lung gene expression profiling of two different wild-type murine strains (C57BL/6J, NZW/LacJ) and two genetic models with mutations in COPD GWAS genes (HHIP, FAM13A) after 6 months of chronic CS exposure and compared the results to human COPD lung tissues. more...
