Hierarchical clustering of ovarian cancer gene. Heat maps depicting hierarchical clustering of gene expression in healthy ovarian tissue, benign ovarian tumours, ovarian cancer and ovarian cancer cell lines. Graphics were generated by means of Partek Genomics Suite™ software. Differentially expressed gene values were included only when fold-change was > 3 and false discovery ratio < 0.005 and only the number of genes clustering to over- expression (top), no significant changes (middle) and under-expression (bottom) are shown. Gene names, RefSeq, and other details are shown in Additional file 2.
