Sample GSM1007868 Query DataSets for GSM1007868
Status Public on Nov 15, 2012
Title 5388438026_E
Sample type RNA
 
Source name Dissected spine
Organism Mus musculus
Characteristics strain: BALB/c
genotype/variation: IL4 knockout
treatment: proteoglycan-induced spondylitis
Extracted molecule total RNA
Extraction protocol Spines were dissected from 4 control and 4 PGISp-affected mice and flash frozen in liquid nitrogen. For the PGISp mice, only mice showing severe peripheral arthritis were selected.
RNA was extracted from the spines using Trizol as per the manufacturers protocol with the extra spin step included as recommended for bone samples then cleaned up using RNAeasy columns.
Label Cy3
Label protocol 500ng of RNA was used in the Illumina TotalPrep cRNA Amplification Kit according to the standard protocol. Samples were hybridised to Mouse Ref-8 Expression BeadChips.
 
Hybridization protocol Standard Illumina hybridization protocol
Scan protocol Standard Illumina scanning protocol
Description RNA extracted from flash frozen mice spines using Trizol
Data processing Array data were processed using the Illumina BeadStudio software then the processed data were assessed for quality control and normalised in Lumi. Analysis of gene expression patterns was performed in BRB-ArrayTools. For quality control scanned images of the arrays were visually inspected for artefacts in Illumina BeadStudio followed by the graphical analysis of density plots in Lumi. The microarray data were transformed by variance stabilization transformation (VST) then normalized by robust spline normalization (RSN). Post-normalization quality control was carried out using density plots to ensure all samples had similar distribution and variance. To reduce background noise in the data analysis all probes that were not expressed in any of the samples, i.e. whose intensity was below background in all samples, were excluded from the analysis. This did not exclude probes for genes whose expression was either “switched-on” or “switched-off”.
