Project description:A large, prospective, non-interventional study was designed to study gene expression changes in peripheral blood mononuclear cells (PBMCs) associated with asthma exacerbations over the course of a year. PBMC samples were collected from subjects at the time of the study visits defined as 1) Quiet: during stable disease at 3 month intervals, 2) Exacerbation: during a 14 day period of deteriorating asthma and 3) Follow-up: within 14 days after cessation of an exacerbation. Gene expression levels during stable asthma, exacerbation, and two weeks after an exacerbation were compared. This series of samples comprises of peripheral blood mononuclear cells (PBMCs) collected during the following study visits (a) quiet (N=394 samples from 118 subjects), (b) exacerbation (N=166 samples from 118 subjects) and (c) follow-up (N=125 samples from 102 subjects)

Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.

Project description:Type 1 diabetes mellitus (T1D) is a common autoimmune disease mediated by autoimmune attack against pancreatic b cells.Dys-regualtion of the component of peripheral blood mononuclear cells (PBMCs), including T-cells and B-cells, and smaller amounts of NK cells and dendritic cells, have all been implicated in this process This study sought to identify T1D associated differently expressed genes in the peripheral blood mononuclear cell (PBMC).

Peripheral blood mononuclear of newly diagnosed type1 diabetes patients and normal controls were purified by LymphoprepTm gradient purification according to the manufacturer’s instructions (Axis-Shield PoC AS, Oslo, Norway) for futher microarray analysis.

Project description:Background: Epigenetic marks, like asthma, are heritable. They are influenced by the environment, direct the maturation of T cellslymphocytes, and have been shown to enhance the development of allergic airways disease in mice. Thus, we hypothesized that epigenetic marks are associated with allergic asthma in inner-city children. Methods: We compared methylation patterns and gene expression in inner-city children with persistent atopic asthma versus healthy controls, using DNA and RNA from peripheral blood mononuclear cells (PBMCs) from inner city children aged 6-12 years with persistent atopic asthma children and healthy controls. Results were externally validated with the GABRIELA study population. Results: Comparing asthmatics (N=97) to controls (N=97), we identified 81 regions that were differentially methylated. Several immune genes were hypomethylated in asthmatics, including IL-13, RUNX3, and a number of specific genes relevant to natural killer cells (KIR2DL4, KIR2DL3, KIR3DL1, and KLRD1) and T cells lymphocytes (TIGIT). 14 differentially methylated regions (DMRs) were associated with the serum IgE concentration of IgE, including RUNX3. These results were internally and externally validated with a global methylation assessment using a different methodology in our inner-city cohort and an independent European cohort (GABRIELA). Hypo- and hypermethylated genes tended to be associated with increased and decreased gene expression, respectively (P<0.6x10-11 for asthma and ; P<0.01 for IgE). To further explore the relationship between methylation and gene expression, we created a matrix of genomic changes in methylation versus transcriptional changes (methyl eQTL) for asthma, and identified cis- and trans-regulated genes whose expression was related to asthma asthma-associated methylation marks. peripheral blood mononuclear cells (PBMCs) from 97 atopic asthmatic and 97 nonatopic nonasthmatic children
