Sample GSM827820 Query DataSets for GSM827820
Status Public on Dec 06, 2011
Title Patient 3, 24 months after start of IFN-beta therapy
Sample type RNA
 
Source name Peripheral blood mononuclear cells
Organism Homo sapiens
Characteristics gender: female
age at ifn-beta therapy onset (baseline blood sampling): 35
duration from ms diagnosis to therapy initiation (in months): 25
edss at baseline: 3.0
edss after 1 year: 2.0
edss after 2 years: 3.0
edss after 5 years: 4.0
number of relapses during the year prior to treatment: 0
number of relapses during 1-year follow-up: 0
number of relapses during 2-year follow-up: 0
number of relapses during 5-year follow-up: 0
time from start of therapy to the first relapse (in months): >60
completed years of ifn-beta therapy: >=5
Treatment protocol Patients were treated with subcutaneous IFN-beta-1a (Rebif, Merck Serono) at standard doses.
Growth protocol Patient blood samples were taken immediately before first IFN-beta injection as well as two days, one month, one year and two years post therapy initiation.
Extracted molecule total RNA
Extraction protocol Blood was separated using isopycnic centrifugation (Ficoll), and peripheral blood mononuclear cells were lysed using chaotropic buffer and cleaned by RNeasy (Qiagen) according to the manufacturers' protocol.
Label Biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 µg total RNA (Expression Analysis Technical Manual, Affymetrix).
 
Hybridization protocol Following fragmentation, 15 µg of cRNA were hybridized for 16 h at 45°C on Affymetrix HG-U133 Plus 2.0 arrays. Microarrays were washed and stained in the Affymetrix Fluidics Station 450.
Scan protocol GeneChips were scanned using the Affymetrix GeneChip Scanner 3000.
Description Gene expression data from a multiple sclerosis patient treated with IFN-beta
Data processing The raw probe-level signals were converted to expression values using the MAS5.0 algorithm and custom GeneAnnot-based chip definition files (version 2.1.0, available at http://www.xlab.unimo.it/GA_CDF). Data normalization was performed by a loess fit to the data with span=0.05 (using R package affy). Each chip yielded mRNA levels of 18,862 human genes.
