Mapping of disease-associated expression polymorphi...
RNA was obtained from peripheral blood CD4+ lymphocytes at four study centers. Peripheral blood (17 cc) was collected into BD Vacutainer CPT tubes (BD Diagnostics, Franklin Lakes, New Jersey) and placed on ice. Samples were centrifuged within 1 hour of collection for 20 minutes at 1700RCF, followed by mononuclear cell layer isolation and suspension in 10 ml of PBS. We isolated CD4+ lymphocytes using anti-CD4+ microbeads by column separation (Miltenyi Biotec, Auburn, CA) using 20 µl anti-CD4+ ...

Lung biopsies from asthmatics pre- and post- steroid...
Endobronchial biopsies from 27 asthmatics and 13 healthy controls were assayed on expression microarrays. Biopsies were obtained from asthmatics before and one week after treatment with Flovent, an inhaled corticosteroid commonly used to treat asthma.

Expression data from human bronchial airway smooth m...
To evaluate IL-17A-inducible gene transcripts, primary human bronchial ASM cells from 3 mild asthmatic and 3 healthy donors were treated for 2h with IL-17 [10ng/ml] and were probed with the Affymetrix GeneChip array. The 2h time point was carefully chosen in order to identify primary response gene targets and to avoid confounding autocrine mechanisms mediating indirect, or late-phase gene expression responses. Non-stimulated ASM cells from the same patients were used as controls.

A sputum gene expression signature of six biomarkers...
Gene expression profiles were generated from induced sputum samples from 47 asthma patients and were grouped by the inflammatory phenotype assigned using sputum cell counts into neutrophilic asthma (n=12), eosinophilic asthma (n=17) and paucigranulocytic asthma (n=18). RNA was extracted, amplified and hybridised to Illumina Sentrix HumanRef-8 Version 2 Expression BeadChips, and genes that were differentially expressed between asthma inflammatory phenotypes were compared.

Asthmatics with exacerbation during acute respirator...
Upon the onset of ‘common cold’, volunteers were instructed to attend the first of three required visits to the study clinic. The first and second visits were designed to obtain samples and clinical data during the early and late stages of symptomatic illness respectively, whereas the third visit would occur when volunteers were asymptomatic and serve as a prospective baseline (BL) for the study.

Expression data from airway epithelial cells from pa...
17 subjects were included in a cross-sectional study (6 allergic asthma and allergic rhinitis; 5 allergic rhinitis; 6 healthy controls). RNA was extracted from isolated and cultured epithelial cells from bronchial brushes and nasal biopsies, and analyzed by microarray (Affymetrix U133+ PM Genechip Array).

To identify gene markers which differentiate between...
Total 24 AERD (Aspirin-exacerbated respiratory disease) and 18 ATA(aspirin-tolerant asthma) samples were used to find bio-markers using 35K op-array.
