(Submitter supplied) We report the impact of side-stream cigarette smoking on baseline tracriptional status of enriched epithelium from the distal lung of both male and female control mice or mice harboring a mutation in the nicotinc alpha7 recptor that selectivley diminshes the calcium current (E260A).

(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...

(Submitter supplied) Human alveolar epithelial cells were exposed to cigarette smoke extract (CSE) for 1, 3 and 5 weeks at 1%, 5% and 10%, and gene expression was evaluated by complete transcriptome microarrays. In this study we explored the effect of cigarette smoke on the gene expression profile.

(Submitter supplied) Our study shows that the aging lung microenvironment shapes the transcriptional phenotype of alveolar macrophages during aging. Except during acute injury when alveolar macrophage differentiation is incomplete, cellular ontogeny makes little difference in determining the transcriptional response of alveolar macrophages. Studies with parabiosis suggest the age-related changes in the alveolar microenvironment occur independently of circulating factors or cells. more...

(Submitter supplied) Smoking is associated with increased airway histamine responsiveness and elevated histamine levels. Transcript levels of histidine decarboxylase (HDC; histamine synthesis) and histamine N-methyltransferase (HNMT; histamine degradation) were evaluated in small airway epithelial (SAE) cells obtained from smokers or non-smokers. Histamine+ SAE cells increased in smokers compared to nonsmokers (p< 0.03). more...

(Submitter supplied) The human small airway epithelium (SAE) plays a central role in the early events in the pathogenesis of most chronic inherited and acquired lung disorders. Little is known about the molecular phenotypes of the specific cell populations comprising the SAE, and the contribution of specific cell populations to the pathogenesis of human disease. There was cell type-specific expression of the genes relevant to the pathogenesis of the inherited pulmonary disorders, genes associated with risk of chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF), and (non-mutated) driver genes for lung cancers. more...
