Renormalised expression data from 1570 breast cancer related samples. Homo sapiens

An integration of several studies normalized to enable consistent cross-study comparisons and enrichment of the less frequent breast cancer types, enabling detection of new potential cancer driver genes. Overall design: Raw Affymetrix CEL files were retrieved from the series GSE2034 GSE11121 GSE20194 GSE1456 GSE2603 GSE6532 GSE20437 GSE1561 GSE7390 GSE5847. Samples were then filtered with a three stage quality control resulting in the final dataset. These were subjected to RMA normalization and then placed on a log2 scale. Samples were stratified by levels of MYC expression with the top quartile defined as High and the bottom quartile defined as Low.
