|
| 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.
