(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is a highly prevalent respiratory disease characterized by airflow limitation and chronic inflammation. MiR-155 is described as an ancient regulator of the immune system. Our objective was to establish a role for miR-155 in cigarette smoke (CS)-induced inflammation and COPD. We demonstrate increased miR-155 expression by RT-qPCR in lung tissue of smokers without airflow limitation and patients with COPD compared to never smokers and in lung tissue and alveolar macrophages of CS-exposed mice compared to air-exposed mice. 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) Our previous study showed that AKR and C57BL/6 mice to cigarette smoke increased lipopolysaccharide (LPS)- induced increased lung vascular permeability. Viremic AKR mice were more susceptible to LPS-induced ALI than C57 on prolonged exposure. In this study we compared the global gene expression patterns to determine the genetic basis for the strain dependent responses to cigarette smoke and LPS-induced ALI. more...

(Submitter supplied) We extracted RNA of sorted lung SPC/GFP+ EpCAM+ cells and performed microarray analyses. Total RNA was extracted from sorted Ep-CAMhigh/GFPhigh cells using TRIzol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer’s protocol. The RNA integrity was examined on an Agilent 2100 BioAnalyzer (Agilent Technologies, Santa Clara, CA). Biotinylated ss-cDNA were prepared according to the standard Affymetrix protocol from 100 ng total RNA using the GeneChip WT PLUS Reagent Kit User Manual (Affymetrix/Thermo Fisher Scientific). more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is characterized by a progressive decline in lung function, caused by exposure to exogenous particles, mainly cigarette smoke (CS). COPD pathogenesis is initiated and perpetuated by an abnormal CS-induced inflammatory response of the lungs, involving both innate and adaptive immunity. Specifically, B cells organized in iBALT structures, as well as macrophages, accumulate in the lungs and contribute to CS-induced emphysema, but the mechanisms thereof remain unclear. more...

(Submitter supplied) Cigarette smoke (CS) imposes a strong oxidative burden on exposed tissues resulting in a severely disturbed oxidant/antioxidant balance, which in the context of chronic exposure is assumed to be a key contributor to CS-related diseases. Because of its emerging central role in orchestrating the general cellular antioxidant response, the pathway leading to the activation of the transcription factor Nrf2 has received mounting attention over the past decade in investigations aimed at elucidating CS-induced patho-physiological mechanisms. more...

(Submitter supplied) We hypothesize that gene expression in the CS-exposed lungs of this strain (A/J) of mice would be able to give clues about the molecular mechanism of emphysema development, thus contributing to this phenotype. More specifically, although imbalance in oxidants/antioxidants and proteinase/antiproteinase pathways drives the pathogenesis of COPD, the molecular mechanisms involved in the development of emphysema are poorly understood. more...

(Submitter supplied) These studies tested the hypotheses that smoke induces changes in mRNA profiles that are dependent on sex and the health status of the lung, and that the effects of smoke are different after 1 day compared to 5 days of smoke exposure. The ways in which the lungs modulate their response to cigarette smoke after repeated exposures are important for understanding the toxicology of smoke, for developing biomarkers of chronic smoke exposure, and for understanding the therapeutic potential in regulatory signaling pathways that are beneficial or detrimental to lung health. more...
