Systemic inflammation is associated with differential gene expression and airway neutrophilia in asthma - GSE43397

Systemic inflammation is reported to be associated with neutrophilic airway inflammation in asthma, this study aimed to examine the molecular mechanisms of the neutrophilia that is associated with systemic inflammation, and hypothesized that asthma patients with systemic inflammation have a group of genes that are differentially expressed and are assciated with airway inflammation.

50 asthma patients were recruited and grouped as asthmatics with systemic inflammation (n=18) and asthamtics without systemic inflammation (n=16) accroding to the levels of serum CRP and IL-6. RNA was extracted from induced sputum and was reverse-transcribed into cDNA. Gene profiling was performed using Illumina Sentrix HumanRef-8 Version 2 Expression BeadChips, and genes that were differentially expressed between asthmatics with systemic inflammation and asthmatics without systemic inflammation were compared and valided using qPCR.

Systemic inflammation (defined in the dataset-associated publication as high CRP and IL-6 plasma levels) (2021 ICD-10-CM code* = Not Applicable)

Sample and gene profiling results were included in the analysis if the sample was of suitable purity (OD 260/280 ratio between 1.7-2.1) and was successfully amplified (sufficient cRNA generated) and hybridized (95th percentile of fluorescence score>500) and the data passed quality control criteria in GeneSpring GX (correlation coefficients and priciple component analysis plots)
