Project description:The purpose of this study was to analyze the transcriptional effects induced by glatiramer acetate treatment (GA; Copaxone, 20 mg injected subcutaneously once daily) in blood monocytes of patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of monocytes from 8 MS patients within the first two months of GA administration. EDTA blood samples were taken from all patients immediately before first and second GA injection as well as after 1 week, 1 month and 2 months. Total RNA of CD14+ monocytes isolated by magnetic-activated cell sorting (MACS) 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:We performed gene expression profiling on paired cerebrospinal fluid (CSF) and peripheral blood lymphocyte (PBL) samples from 26 Multiple sclerosis patients without immunomodulatory treatment sampled in relapse or in remission, and 18 controls with other non-inflammatory neurological disorders using Human Genome U133 plus 2.0 arrays (Affymetrix).
