Extracted molecule total RNA
Extraction protocol Total RNA was extracted from freshly frozen tumor tissue using Trizol Reagent (Invitrogen) and RNeasy Micro Kit (Qiagen).
Label Cy3
Label protocol RNA was amplified and labeled using the Amino Allyl MessageAmp II aRNA Amplification Kit (Ambion) according to the manufacturer’s protocol.
 
 
Hybridization protocol Hybridization and washing were performed according to manufacture’s recommendations in a low ozone environment.
Scan protocol Scanned using a Agilent G2565CA Microarray scanner
Description A173
Data processing Scanned images were quantified using Agilent Feature Extraction Software (version 10.7.3.1). Bad quality features flagged during feature extraction were removed and the remaining data were pre-processed. Data were background corrected (normexp, offset=50), then within-array normalized by loess normalization method and between-array normalizatized by the quantile method. The normalized values were used to calculate log2 transformed Cy5/Cy3 ratios. Replicate probes were collapsed by calculating the median. Probes without gene symbol annotation were filtered out. In cases of multiple probes per gene symbol only the probe with the maximum mean (Cy5) intensity was kept. Missing expression values were imputed by k-nearest neighbors averaging (k = 10).
