TranscriptomicsTranscription profiling of human airway epithelium, large airways, phenotypically normal smokers vs non-smokers, MAS5 (HuGeneFL)
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 44 HuGeneFL GeneChips, from 9 normal non-smokers and 13 phenotypic normal smokers, large airways, 2 samples per individual, one ...

TranscriptomicsTranscription profiling of human alveolar macrophages from phenotypically normal smokers compared to non-smokers to identify new genes linking to early events in the molecular pathogenesis of COPD
Cigarette smoking is the leading cause of the respiratory diseases collectively known as chronic obstructive pulmonary disease (COPD). While the pathogenesis of COPD is complex, there is abundant evidence that alveolar macrophages (AM) play an important role. Based on the concept that COPD is a slow...

TranscriptomicsThe Human Airway Epithelial Basal Cell Transcriptome
Background. The human airway epithelium consists of 4 major cell types: ciliated, secretory, columnar and basal cells. During natural turnover and in response to injury, the airway basal cells function as stem / progenitor cells for the other airway cell types. The objective of this study is to bett...

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...

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...

TranscriptomicsDisparate Oxidant-related Gene Expression of Human Small Airway Epithelium Compared to Autologous Alveolar Macrophages
Disparate Oxidant-related Gene Expression of Human Small Airway Epithelium Compared to Autologous Alveolar Macrophages in Response to the In Vivo Oxidant Stress of Cigarette Smoking The oxidant burden of cigarette smoking induces lung cell dysfunction, and play a significant role in the pathogenesis...

TranscriptomicsSmoking-induced Wnt pathway downregulation
The Wnt pathway plays a central role in controlling differentiation of epithelial tissues; when Wnt is on, differentiation is suppressed, but when Wnt is off, differentiation is allowed to proceed. Based on this concept, we hypothesized that expression of key genes in the Wnt pathway are suppressed ...

TranscriptomicsCigarette Smoking Induces Overexpression of a Fat Depleting Gene AZGP1 in the Human Airway Epithelium
Smokers weigh less and have less body fat than non-smokers, and increased body fat and weight gain are observed following smoking cessation. To assess a possible molecular mechanism underlying the inverse association between smoking and body weight, we hypothesized that smoking may induce the expres...

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...

TranscriptomicsPOU2AF1 Functions in the Human Airway Epithelium to Regulate Expression of Host Defense Genes [RNA-Seq]
In the process of seeking novel lung host defense regulators by analyzing genome-wide RNA sequence data from normal human airway epithelium, we detected expression of POU2AF1, a known transcription co-factor previously thought to be expressed only in lymphocytes. Lymphocyte contamination of human ai...
