DNA-RNA correlation for EVI1. A heatmap illustrating the mRNA and DNA correlation for the EVI1 gene and its locus 3q26.2. Red represents gain and high mRNA expression, respectively, whereas green represents no gain and low expression. Black represents intermediate levels of mRNA expression. In the left panel, tumors were clustered hierarchically according to similarity, using both copy number and expression level in the distance calculation (Euclidean). The chemotherapy response status of the samples is indicated vertically for each sample respectively. R = resistant case, S = sensitive case.
