BCL6 target genes are preferentially repressed in BCR and GCB-type DLBCLs. The figure shows a graphical representation depicting the abundance of BCL6 targets among genes that are either repressed or up-regulated in (A) BCR versus OxPhos and (B) GCB versus ABC DLBCLs. Each panel contains a plot in which the x-axis represents all of the genes contained in our promoter arrays distributed according to whether they are repressed preferentially in BCR (A left) or OxPhos (A right), or in GCB (B left) or ABC (B right). The y-axis represents the percentage of these genes that were found to be BCL6 targets by ChIP-on-chip. The dotted line represents the percentage of genes that would be expected to be BCL6 targets if the BCL6 targets were uniformly distributed across the range of relative expression values. The statistical significance of the enrichment for BCL6 target genes is indicated by the heatmap that is below each of the plots, as shown in the heatmap color code at the bottom of the figure.
