TranscriptomicsTranscription profiling of human alveolar macrophages in response to P. aeruginosa and B. cepacia infections
To determine if differences in the severity of pulmonary infection in cystic fibrosis been seen in late isolates od Pseudomonas aeruginosa and Burkholderia cepacia are associated with differences in the initial repsonse of alveolar macrophages (AM) to these pathogens, we assessed gene expression cha...

TranscriptomicsTranscription profiling of human airway epithelium, large airways, from phenotypically normal smokers vs non-smokers
Upregulation of Expression of the Ubiquitin Carboxyl Terminal Hydrolase L1 Gene in Human Airway Epithelium of Cigarette Smokers; The microarray data deposited here is from 11 HG-U133A GeneChips, from 5 normal non-smokers and 6 phenotypic normal smokers, large airways. Samples from the small airways ...

TranscriptomicsEpithelial Expression of Toll-like Receptor 5 is Modulated in Healthy Smokers and Smokers with Chronic Obstructive Lung Disease
The toll-like receptors (TLRs) are important components of the respiratory epithelium host innate defense, enabling the airway surface to recognize and respond to a variety of insults in inhaled air. Based on the knowledge that smokers are more susceptible to pulmonary infection and the airway epith...

TranscriptomicseQTL analysis of many thousands of expressed genes while simultaneously controlling for hidden factors
Motivation: Identification of eQTL, the genetic loci that contribute to heritable variation in gene expression, can be obstructed by factors that produce variation in expression profiles if these factors are unmeasured or hidden from direct analysis. Methods: We have developed a method for Hidden Ex...

TranscriptomicsModulation of Cystatin A Expression in Human Airway Epithelium Related to Genotype, Smoking COPD and Lung Cancer
Cystatin A (gene: CSTA), is up-regulated in non-small-cell lung cancer (NSCLC) and dysplastic vs normal human bronchial epithelium. In the context that chronic obstructive pulmonary disease (COPD), a small airway epithelium (SAE) disorder, is independently associated with NSCLC (especially squamous ...

TranscriptomicsSmoking-dependent Reprogramming of Alveolar Macrophage Polarization: Implication for Pathogenesis of COPD
Background: When exposed to specific stimuli, macrophages exhibit distinct activation programs, M1 and M2 polarization, that define macrophage function as inflammatory/immune effectors or anti-inflammatory/tissue remodeling cells, respectively. Due to their position on the lung epithelial surface, a...

TranscriptomicsSmoking-induced Disarray of the Apical Junctional Complex Gene Expression Architecture in the Human Airway Epithelium
The apical junctional complex (AJC), composed of tight junctions and adherens junctions, is essential for maintaining epithelial barrier function. Since cigarette smoking and chronic obstructive pulmonary disease (COPD), the major smoking-induced disease, are both associated with increased lung epit...

TranscriptomicsRNA-Seq Quantification of the Transcriptome of Genes Expressed in the Small Airway Epithelium of Nonsmokers and Smokers
The small airway epithelium (SAE) the pseudostratified epithelium that covers the majority of the human airway surface from the 6th generation to the alveoli, is the major site of lung disease caused by smoking, and the cell population that exhibits the earliest manifestations of smoking-induced dis...

TranscriptomicsCigarette Smoking Induces Small Airway Epithelial Epigenetic Changes with Corresponding Modulation of Gene Expression
The small airway epithelium (SAE), the first site of smoking-induced lung pathology, exhibits genome-wide changes in gene expression in response to cigarette smoking. Based on the increasing evidence that the epigenome can respond to external stimuli in a rapid manner, we assessed the SAE of smokers...

TranscriptomicsThreshold of Biologic Response of the Small Airway Epithelium to Low Levels of Tobacco Smoke
Background: Healthy individuals exposed to low levels of cigarette smoke have a decrement in lung function and higher risk for lung disease compared to unexposed individuals. We hypothesized that healthy individuals exposed to low levels of tobacco smoke must have biologic changes in the small airwa...
