Multiple Sclerosis Blood Cell mRNA Transcriptome

ABSTRACT: We measured mRNA expression for all known genes in whole blood from 144 individuals, 99 with MS (43 PPMS, 36 RRMS and 20 SPMS). Analysis of gene expression and genotype in these individuals has indicated the dominant genetic association with T cell regulation is matched by the dominant pattern of dysregulation of T cell gene expression in MS and its clinical subtypes. Whole blood mRNA expression was compared between different types of MS and age-matched healthy control to identify differentially expressed genes between them. The supplementary file 'GSE17048_non-normalized_data.txt' contains non-normalized data for Samples GSM426595-GSM426738.

Multiple sclerosis (MS) is an autoimmune disease with a genetic component, caused at least in part by aberrant lymphocyte activity. The whole blood mRNA transcriptome was measured for 99 untreated MS patients: 43 primary progressive MS, 20 secondary progressive MS, 36 relapsing remitting MS and 45 age-matched healthy controls. The ANZgene Multiple Sclerosis Genetics Consortium genotyped more than 300 000 SNPs for 115 of these samples. Transcription from genes on translational regulation, oxidati ...[more]

Whole blood RNA-seq data of SPMS vs RRMS patients from paper titled \"Relapsing remitting and secondary progressive multiple sclerosis are characterised by distinct metabolomic and transcriptomic signatures that could aid patient management strategies\\

Project description:We combined analysis of serum metabolomics and whole blood transcriptomics in patients with RRMS and SPMS to build an integrated network describing these different phases of MS and to help improve our understanding of the potential mechanisms driving disease progression. Transcriptomic analysis of whole blood was performed to assess differential gene expression between five patients with RRMS and eight patients with SPMS.

Novel Biomarkers and Interferon Signature in Secondary Progressive Multiple Sclerosis

Project description:Transcriptome analysis of RNA samples from human PBMCs of IFN-beta-1a (Rebif) therapy in secondary progressive multiple sclerosis (SPMS) patients. Objective: Untreated multiple sclerosis is inflammatory, with decreased immune control and subnormal type I interferon (IFN) signaling. IFN-ß therapy corrects abnormal IFN-ß signaling, reduces inflammation on MRI, exacerbations, and disease worsening in relapsing-remitting MS (RRMS). For unclear reasons, secondary progressive MS (SPMS) exhibits waning attacks, relentless neurodegeneration, and diminished benefits of therapy. Methods: Peripheral blood mononuclear cells and serum were from 10 healthy controls (HC), 9 therapy-naive RRMS, 20 therapy-naïve SPMS, and 10 IFN-ß-treated SPMS patients after therapy washout and four hours after IFN-ß-1a injection. Global gene expression was assayed with sensitive RNA microarrays and multiplexed serum immune and neuroprotective protein assays. Results: Therapy-naive RRMS cells displayed 8,723 differentially expressed genes (DEG), compared to HC, vs. d only 3,936 DEG in therapy-naive SPMS. In SPMS, gene expression was subnormal in the WNT/ß-catenin pathway that suppresses inflammation and enhances blood-brain barrier integrity. Olfactory receptor (OR) genes, linked to lymphocyte migration, were overexpressed in RRMS (111 DEG), intermediate in SPMS (34 DEG) vs. HC, differentiating RRMS from SPMS (p < 0.007). IFN-ß injections in SPMS decreased expression of pro-inflammatory genes and increased anti-inflammatory, anti-oxidant metallothionein genes. Pro-inflammatory and anti-inflammatory protein levels were balanced in HC, disrupted in RRMS, and intermediate in SPMS. Interpretation: Aberrant gene expression seen in RRMS wanes in SPMS, paralleling fewer clinical exacerbations and diminished therapeutic responses. Novel biomarkers for SPMS suggest new targets to correct subnormal immune regulation and brain repair in this neurodegenerative disease.

CSF B cells in relapsing multiple sclerosis are driven towards an antigen-experienced, inflammatory fate

Project description:Central nervous system B cells have several potential roles in multiple sclerosis (MS): secretors of proinflammatory cytokines and chemokines, presenters of autoantigens to T cells, producers of pathogenic antibodies, and reservoirs for viruses that trigger demyelination. To interrogate these roles, single-cell RNA sequencing (scRNA-Seq) was performed on paired cerebrospinal fluid (CSF) and blood from subjects with relapsing-remitting MS (RRMS; n = 12), other neurologic diseases (ONDs; n = 1), and healthy controls (HCs; n = 3). Single-cell immunoglobulin sequencing (scIg-Seq) was performed on a subset of these subjects and additional RRMS (n = 4), clinically isolated syndrome (n = 2), and OND (n = 2) subjects. Further, paired CSF and blood B cell subsets (RRMS; n = 7) were isolated using fluorescence activated cell sorting for bulk RNA sequencing (RNA-Seq). Independent analyses across technologies demonstrated that nuclear factor kappa B (NF-?B) and cholesterol biosynthesis pathways were activated, and specific cytokine and chemokine receptors were up-regulated in CSF memory B cells. Further, SMAD/TGF-ß1 signaling was down-regulated in CSF plasmablasts/plasma cells. Clonally expanded, somatically hypermutated IgM+ and IgG1+ CSF B cells were associated with inflammation, blood–brain barrier breakdown, and intrathecal Ig synthesis. While we identified memory B cells and plasmablast/plasma cells with highly similar Ig heavy-chain sequences across MS subjects, similarities were also identified with ONDs and HCs. No viral transcripts, including from Epstein–Barr virus, were detected. Our findings support the hypothesis that in MS, CSF B cells are driven to an inflammatory and clonally expanded memory and plasmablast/plasma cell phenotype.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy [miRNA-2_0]

Project description:The purpose of this study was to investigate the expression dynamics of mRNAs and microRNAs in response to subcutaneous IFN-beta-1b treatment (Betaferon, 250 Âµg every other day) in patients with clinically isolated syndrome (CIS) suggestive of multiple sclerosis (MS) or relapsing-remitting type of the disease (RRMS). By using Affymetrix microarrays, we obtained microRNA expression profiles of peripheral blood mononuclear cells from 3 MS patients within the first month of IFN-beta treatment. EDTA blood samples were taken from all patients immediately before first IFN-beta injection as well as after 1 month. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix GeneChip miRNA 2.0 arrays to quantify the expression of small non-coding RNA transcripts. This GEO entry provides the GeneChip miRNA 2.0 microarray data.

Identification the proteins interacted with SNHG26 in human keratinocytes

Project description:The cell transition from an inflammatory phase to a subsequent proliferative phase is crucial for wound healing, yet the driving mechanism remains unclear. By profiling lncRNA expression changes during human skin wound healing and screening lncRNA functions, we identified SNHG26 as a pivotal regulator in keratinocyte progenitors underpinning this phase transition. To study the proteins interact with SNHG26, we performed RNA pull-down assay in human keratinocyte progenitors. The mass spectrometry (MS) analysis was performed to identify the proteins interacted with SNHG26.
