(Submitter supplied) Comparison of severely emphysematous tissue removed at lung volume reduction surgery to that of normal or mildly emphysematous lung tissue resected from smokers with nodules suspicious for lung cancer. Data obtained from the 18 patients with severe emphysema and 12 patients with mild/no emphysema. Research may provide insights into the pathogenetic mechanisms involved in chronic obstructive pulmonary disease (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...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is a major public health problem. The aim of this study was to identify genes involved in emphysema severity in COPD patients. Gene expression profiling was performed on total RNA extracted from non-tumor lung tissue from 30 smokers with emphysema. Class comparison analysis based on gas transfer measurement was performed to identify differentially expressed genes. more...

(Submitter supplied) Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characterized by varying degrees of emphysematous lung destruction and small airway disease, each with distinct effects on clinical outcomes. There is little known about how microRNAs contribute specifically to the emphysema phenotype. We examined how microRNA expression is altered with regional emphysema severity within the lung and how these microRNAs regulate disease-associated gene-expression networks. more...

(Submitter supplied) BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease consisting of emphysema, small airway obstruction, and/or chronic bronchitis that results in significant loss of lung function over time. METHODS: In order to gain insights into the molecular pathways underlying progression of emphysema and explore computational strategies for identifying COPD therapeutics, we profiled gene expression in lung tissue samples obtained from regions within the same lung with varying amounts of emphysematous destruction from smokers with COPD (8 regions x 8 lungs = 64 samples). more...
