Gene expression data on lungs of wild-type and Rora (Retinoic acid related orphan receptor) mutant mice exposed to room air and smoke

ABSTRACT: Gene expression data on wild-type and Rora mutant mice exposed to room air and smoke. The results provide a general insight into the relationship of Rora to known DNA damage response pathways and its role in cigarette smoke-induced airspace enlargement.

Haploinsufficiency of Hedgehog interacting protein causes increased emphysema induced by cigarette smoke through network rewiring

Project description:BACKGROUND: The HHIP gene, encoding Hedgehog interacting protein, has been implicated in chronic obstructive pulmonary disease (COPD) by genome-wide association studies (GWAS), and our subsequent studies identified a functional upstream genetic variant that decreased HHIP transcription. However, little is known about how HHIP contributes to COPD pathogenesis. METHODS: Here, we exposed Hhip haploinsufficient mice (Hhip+/-) to cigarette smoke (CS) for 6 months to model the biological consequences caused by CS in human COPD risk-allele carriers at the HHIP locus. Gene expression profiling in murine lungs was performed followed by an integrative network inference analysis, PANDA (Passing Attributes between Networks for Data Assimilation) analysis. RESULTS: We detected more severe airspace enlargement in Hhip+/- mice vs. wild-type littermates (Hhip+/+) exposed to CS. Gene expression profiling in murine lungs suggested enhanced lymphocyte activation pathways in CS-exposed Hhip+/- vs. Hhip+/+ mice, which was supported by increased numbers of lymphoid aggregates and enhanced activation of CD8+ T cells after CS-exposure in the lungs of Hhip+/- mice compared to Hhip+/+ mice. Mechanistically, results from PANDA network analysis suggested a rewired and dampened Klf4 signaling network in Hhip+/- mice after CS exposure. CONCLUSIONS: In summary, HHIP haploinsufficiency exaggerated CS-induced airspace enlargement, which models CS-induced emphysema in human smokers carrying COPD risk alleles at the HHIP locus. Network modeling suggested rewired lymphocyte activation signaling circuits in the HHIP haploinsufficiency state. Total RNA was obtained from the lung tissue of C57BL/6J mice exposed to cigarette smoke (CS) or filtered air (air) for 6 months. Six mice from each of four groups with different genotypes (Hhip+/+ or Hhip+/-) and treatments (air or CS) were randomly chosen for gene expression profiling

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.

Mepenzolate bromide displays beneficial effects in a mouse model of chronic obstructive pulmonary disease

Project description:For the clinical treatment of chronic obstructive pulmonary disease (COPD), it is important not only to improve the airflow limitation by bronchodilation but also to suppress emphysema by controlling inflammation. In this study, we have screened for compounds that prevent elastase-induced airspace enlargement in mice from medicines already used clinically. Mepenzolate bromide, a muscarinic antagonist used to treat gastrointestinal disorders was selected. Intratracheal administration or inhalation of mepenzolate bromide decreased the severity of elastase-induced airspace enlargement, alteration of lung mechanics and respiratory dysfunction. While mepenzolate bromide showed bronchodilatory activity, most of other muscarinic antagonists tested did not improve the elastase-induced pulmonary disorders. Mepenzolate bromide suppressed elastase-induced pulmonary inflammatory responses and production of superoxide anions, and reduced the level of cigarette smoke-induced airspace enlargement and alteration of lung mechanics. Based on these results, we propose that this drug is therapeutically effective for COPD as a consequence of both its anti-inflammatory and bronchodilatory activities.

Nanostring immune profiling of air and cigarette smoke exposed wildtype bone marrow hematopoietic cells and Nanostring immune profiling of air and cigarette smoke exposed bone marrow hematopoietic cells from mice containing Jak2V617F mutant cells

Project description:Extrinsic stressors must have a role in driving clonal hematopoiesis since only a fraction of individuals with clonal hematopoiesis of indeterminate potential (CHIP) develop hematologic malignancy. Smoking behavior is associated with CHIP, but the effects of cigarette smoke on hematopoietic stem cells (HSCs) are unknown. The exploding use of electronic (E)-cigarettes has led to significant concern on their health effects. In this project, we aimed to determine the impact of cigarette smoke on the frequency and numbers of HSCs and inflammatory gene expression changes in bone marrow hematopoietic cells using wildtype mice. We also determined if cigarette smoke drives clonal expansion in mosaic mice containing both wildtype and Jak2V617F mutant cells. We also performed gene expression profiling on the wildtype fraction of bone marrow hematopoietic cells from mosaic mice exposed to cigarette smoke or air to determine if the presence of mutant cells alters the signature of wildtype cells.
