Figure 1

Treeview of differential gene expression data from bone metastatic breast cancer cell line, MDA-231BO vs. primary breast cancer cell line, MDA-231). Treeview demonstrates the differential gene profiles in the bone metastatic breast cancer cell line compared to primary breast cancer cell line. Up-regulation is indicated by red, down-regulation by green, and no significant change by dark. Figure 1 shows 50 genes with greatest differential expression in five cDNA microarray experiments.
