Gene expression analysis. Expression level fold change for differential expressed genes after knockdown of GATA-1 in K562 cells. The proportion of differential expressed genes in the different clusters is shown above each bar, where purple indicates overexpression, while cyan displays underexpressed genes. Only the known genes that are univocally associated to a single cluster are shown. Bonferroni corrected p-values of Fisher’s exact test on the percentage of overexpressed genes (as explained in Method) are shown with asterisks (with codes: <0.001 ‘***’, <0.01 ‘**’, <0.05 ‘*’). Gene expression analysis results obtained with less and more restrictive definition of promoter regions can be found in Additional file 1: Figure S15
