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.
Project description:RNA was isolated from fresh cerebrospinal fluid samples of multiple sclerosis and control patients and analyzed by hybridization of HG U133 plus 2.0 arrays in order to investigate disease mechanisms of multiple sclerosis and to identify transcriptional biomarker
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 µg 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.
