| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was isolated using TRIzol reagent (Invitrogen), followed by RNA clean-up using the QIAGEN Rneasy mini kit (Qiagen GmbH, Hilden, Germany) according to manufacturers instructions. RNA concentration was measured spectrophotometrically and the fragment sizes were determined using RNA 6000 Nano Labchip kit.

| Description |
Note: this sample is previously uploaded under GEO accession number GSM564794. However, the current sample is normalized on a different dataset.
|
| Data processing |
For the expression array, unprocessed data were collected from BeadStudio and processed using variance-stabilizing transformation (vst) and robust spline normalization (rsn) with the Bioconductor package lumi. The processed data was analyzed using LIMMA (linear models for microarray data) analysis, which uses moderated t-test to detect differentially expressed genes between two groups by taking into account natural variance within these groups and correcting for multiple testing using false discovery rate indicating the number of differentially expressed genes between two groups.
Raw data file description: On the Illumina BeadChips, each sample is hybridized on 2 chips, which together compromise all probes per sample. There are four columns in each file. The first column represents the bead (there are approximately 30 replicate beads per probe on random positions on the Illumina BeadChip arrays, so the data that is generated is higly robust), the second the signal, and the other 2 the X and Y locations on the chip. These 2 raw files can be imported into BeadStudio, the program developed by Illumina for analyzing these data, or into R package beadarray.
