Identification of genes involved in breast cancer metastasis. The schematic representation of the research strategy for cross-species integrative expression profiling. The numbers indicate the differentially expressed genes after each comparison. Differential expression was calculated for the highly metastatic cell line versus the poorly metastatic cell line data sets using an algorithm provided by Bead Studio. Fold enrichment values were used to obtain the list of candidates with greater than a 2-fold change.
