Organism Homo sapiens
Characteristics reference: Universal Human Reference RNA (Stratagene)
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 Fragmentation, hybridization and washing for the spotted arrays were carried out using Agilent Gene Expression Hybridization Kit (Agilent Technologies ) and Gene Expression Wash Buffer Kit (Agilent Technologies) according to the manufacturer’s protocol in a low ozone environment.
Scan protocol Scanned using a Agilent G2565CA Microarray scanner
Description K014
Data processing Scanned images were quantified by Gene Pix Pro 6.0 (Molecular Devices). 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. The 92 samples were processed together with 154 other breast tumor samples. ComBat method was used for adjustment of the batch effects across the different spotting batches [PMID: 16632515]. 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).
