The reliability of the microarray data generated from our multi-comparison analysis is demonstrated by the consistent identification of a set of genes among multiple comparisons, of which a subset of genes were confirmed by immunocytochemistry. For immunochemistry (IC): +, moderate to strong staining; -, negative staining; +/-, very weak staining. For Affymetrix arrays:+, detected as up-regulated in BCs; --, not detected as up-regulated in BCs.
