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

ABSTRACT: 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.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1b treatment (Betaferon, 250 µg every other day) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 25 MS patients within the first two years of IFN-beta administration. EDTA blood samples were drawn from all patients immediately before first, second, month 1, 12, and 24 IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy [HG-U133_Plus_2]

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 gene expression profiles of peripheral blood mononuclear cells from 6 MS patients within the first month of IFN-beta treatment. EDTA blood samples were taken from all patients immediately before first, second and third 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 Human Genome U133 Plus 2.0 arrays to quantify the mRNA levels. This GEO entry provides the U133 Plus 2.0 microarray data.

Expression data of multiple sclerosis patients receiving subcutaneous Interferon-beta-1a therapy [U133 Plus 2.0]

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1a treatment (Rebif, 22 µg or 44 µg three times a week) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 12 MS patients within the first two years of IFN-beta administration. EDTA blood samples were taken from all patients immediately before first and second IFN-beta injection as well as after 1 month, 1 year and 2 years. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix Human Genome U133 Plus 2.0 arrays to quantify the mRNA levels. This GEO entry provides the U133 Plus 2.0 microarray data.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy

Project description:The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 Âµg once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration. Keywords: Multiple sclerosis, Interferon, Pharmacogenomics, Affymetrix EDTA blood samples were taken from all patients immediately before first, second and fifth IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.

Gene expression data: Plasmacytoid dendritic cells (pDCs) of healthy donors and MS patientes before and after IFN beta treatment

Project description:Multiple Sclerosis (MS) is an immune-mediated chronic inflammatory disease affecting the central nervous system. The cause of MS is not known and the mechanism of IFN-beta, a disease-modifying treatment (DMT) approved for MS, is not well-understood. Oligonucleotide microarrays were used to study gene expression in plasmacytoid denditic cells (pDCs) which are antigen-presenting cells implicated in MS pathogenesis. We analyzed gene expression in pDCs of healthy controls, untreated and IFN-beta treated MS patients. We were able to identify 60 genes which were abnormally expressed in untreated MS patients and were corrected after treatment with IFN-beta. PDCs were separated from healthy donors and MS patients at two time points: before and 3 months after initiation of treatment with IFN-beta for RNA extraction and hybridization on Affymetrix microarrays. Gene expression data analysis of was done by GeneSpring software (Agilent Technologies). An unpaired t-test was applied to select genes with significant difference in expression between healthy donors and untreated MS patients. A paired t-test was applied to select genes with significant difference in expression in MS patients before and after IFN-beta treatment. To select differentially expressed/regulated genes, the cut-off criteria consisted of a P value < 0.05 and fold change >1.5.
