| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated using TRIZOL reagent (Invitrogen) followed by RNeasy mini kit with DNase on-column digestion (Qiagen). RNA was quantified with NanoDrop ND-1000 followed by quality assessment with the 2100 Bioanalyzer (Agilent) according to manufacturer’s protocol
|
| Label |
Cy3
|
| Label protocol |
Total RNA was labeled using Agilent Low RNA Input Fluorescent Linear Amplification Kit (Agilent) following the manufacturer’s instruction with minor modifications. Briefly, 0.4 µg RNA was reverse-transcribed into cDNA by MMLV-RT using an oligo dT primer (System Biosciences) that incorporated a T7 promoter sequence. The cDNA was then used as a template for in vitro transcription in the presence of T7 RNA polymerase and Cyanine-3 labeled CTPs (Perkin Elmer). RNA spike-in controls (Agilent) were added to RNA samples before amplification and labeling. The labeled cRNA was purified using RNeasy mini kit (Qiagen).

| Hybridization protocol |
Total 0.825 µg of each Cy3-labeled sample was used for hybridization on Agilent 4x 44K whole human genome microarray at 65ºC for 17 hours in a hybridization oven with rotation.
|
| Scan protocol |
Slides were scanned using the Agilent Microarray Scanner controlled by Agilent Scan Control 7.0 software.

| Description |
N2
|
| Data processing |
Microarray data were extracted with Agilent Feature Extraction 9.5.3.1 software and imported into GeneSpring GX 9.0.1 (Agilent). Normalization was done with all intensities higher than 5, log2 transformation and cross-array quartile normalization. Features with intensities smaller than 300 at all time points were excluded from the analysis.
