Comparison of bronchial epithelial cells obtained by bronchoscopy from mild asthma patients, moderate asthma patients, severe asthma patients and healthy controls

ABSTRACT: In this study we explore the underlying differences in bronchial epithelial cells from asthma patinets compared to healthy controls. In addition we also explore the differential gene expression of severe asthma patients compared to mild and moderate asthma patients to determine if there are genes that lead to severity of the disease

Comparison of bronchial epithelial cells obtained by bronchoscopy from severe asthma patients before and after thermoplasty treatment

Project description:In this study we explore the underlying differences in bronchial epithelial cells from severe asthma patients obtained before and after thermlasty treatment. The effect of the treatment on bronchial epithelial cells will be revealed based on the genes differentialy expressed post treatment.

Expression data from bronchial epithelial cell obtained before and after bronchial thermoplasty treatment in severe asthma

Project description:Biological mechanisms explaining asthma control improvement following bronchial thermoplasty are still not well understood. We used a large-scale transcriptomic approach to evaluate the transcriptome of bronchial epithelial cell (BEC) obtained before and after bronchial thermoplasty treatment (BT).

Gene signature profiles in bronchial tissues from severe asthma patients treated with bronchial thermoplasty

Project description:Bronchial thermoplasty (BT) is an endoscopic therapy employed for the treatment of refractory asthma. However, no predictive factors are available that determine the effectiveness of BT in treating asthma patients. The present study aimed to comprehensively analyze RNA samples from the airway bronchial tissues of 8 patients with severe asthma treated by BT, and to characterize each patient as a BT responder or non-responder. Total 24 RNA samples (three per patient prior to BT1 [baseline], prior to BT2 [after 1st time treatment], and prior to BT3 [after 2nd time treatment]) were obtained. There were 975 differentially expressed (DE) genes in the bronchial tissues of 8 patients between prior to BT1 (baseline) and prior to BT2 (after 1st time treatment), with significant differences (FDR-adjusted P<0.05). Subjects with an Asthma Quality of Life Questionnaire score change of >0.5 for a period of 12 months were considered BT responders. Non-responders exhibited a score change of <0.5 for 12 months. Transcriptome analysis at baseline identified 67 genes that were differentially expressed between responders and non-responders, including SLPI, MMP3, and MUC19 which were upregulated in responders.

Whole lung transcriptomics of a house dust mite model of mild/moderate asthma

Project description:Purpose: Identify whole lung gene expression patterns in a house dust mite model of mild/moderate asthma Methods: Lung gene expression profiles of 10 week old BALB/c female mice were generated by ribosome-depleted, 150 nt, paired-end, stranded RNA-seq with Illumina HiSeq v4. Sequence reads that passed quality filters after trimming were analyzed with Sailfish-cir to identify linear RNAs and circular RNAs. Differential expression of linear RNAs was assessed with Deseq2 . QRT–PCR validation was performed using TaqMan and SYBR Green methods. Results: 100 million sequence reads per sample were mapped to the mouse genome (build mm10) using Sailfish-cir to identify linear and circular RNA transcripts. Pathway analysis of differentially expressed genes identified upregulation of gene sets for human asthma, mouse lung allergic inflammation, Muc5ac regulated genes and smooth muscle genes after allergic sensitization. Gene level exppression in each asthma-related pathway was reduced by the miR-145 antagonist. The miR-145 antagonist and several nontargeting oligos also upregulated interferon signaling pathways suggesting a general antiinflammatory effect of LNA/DNA oligos in the lung. Conclusions: Lung-directed delivery of LNA/DNA oligonucleotides with cationic lipid nanoparticles is an efffective means to prevent inflammatory gene expression in a house dust mite model of mild/moderate asthma.

Expression data from peripheral blood mononuclear cells(PBMCs) of patients with bronchial asthma and normal controls

Project description:Bronchial asthma is a heterogeneous disease with distinct disease phenotypes and underlying pathophysiological mechanisms. LncRNAs involves in numerous functionally different biological and physiological processes. The aim of this study is to identify the differentially expressed lncRNAs and mRNAs in patients with asthma and to further explore the functions and interactions between lncRNAs and mRNAs. Ten patients with asthma and 9 healthy controls were enrolled in this study. We used microarray analysis to identify lncRNA and mRNA expression in their PBMC.

Distinct molecular profiles underpin mild to moderate equine asthma cytological profiles

Project description:This project used a state-of-the-art, multi-omics approach to improve our understanding of the aetiopathogenesis of a highly prevalent, performance-limiting disorder of racehorses; mild to moderate equine asthma (MMEA). This advanced knowledge is a prerequisite to improving prophylactic, management and therapeutic options for this condition. Although a number of risk factors for MMEA have been identified, incomplete understanding of the precise aetiopathogenesis of this syndrome means that options for intervention are currently limited. This study aimed to apply a multi-omic approach, reveal key inflammatory pathways involved in inflammatory cell recruitment to the lower airways and highlight pathways specific to different MMEA inflammatory cell profiles (MMEA endotypes). Thus, we compared BALF cell gene and protein expression data from horses with normal bronchoalveolar lavage fluid (BALF) cytology (n = 8) with those isolated from horses with neutrophilic (n = 4), mastocytic (n = 8), mixed neutrophilic/mastocytic (n=4) and mixed eosinophilic/mastocytic (n=3) inflammation. Analyses on transcriptomic and proteomic data derived from BALF cells from horses with neutrophilic cytology showed enrichment in classical inflammatory pathways, while horses with mastocytic cytology showed enrichment in pathways involved in hypersensitivity reactions related to non-classical inflammation that could mimic a Th2 immune response. The mixed eosinophilic/mastocytic group also presented with a non-classical inflammatory profile while, the mixed neutrophilic/mastocytic group revealed profiles consistent with both neutrophilic inflammation and hypersensitivity. Our adopted multi-omics approach (both gene and protein expression) has enabled a more holistic assessment of the immunological status of the lower airways associated with the different cytological profiles of equine asthma.

Expression profiling in blood from subjects with severe asthma, moderate asthma, and non-asthmatics collected in the U-BIOPRED study

Project description:Severe asthma is a collection of disease entities with varying pathophysiological characteristics (7) that result in symptoms of cough, wheeze and breathlessness, with frequent exacerbations. To address the problem of phenotypic difference and heterogeneity, the Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED) project was set up as a public-private partnership within the framework of the Innovative Medicines Initiative (IMI), engaging academia, the pharmaceutical industry and patient groups. The goal of this investigation was to identify transcript fingerprints in whole blood that characterize patients with severe asthma and to determine whether subgroups of severe asthmatics can be identified. Furthermore, we were interested in elucidating the biological pathways that showed differences between subgroups.
