Based on these results, the published ChIP-seq results showing that these promoters are occupied by Myb proteins in ACC tumors, and the tight correlation between MYB/MYBL1, EN1 and SOX4 RNA levels in ACC tumor samples, we conclude that EN1 and SOX4 are likely to be direct targets of regulation by Myb proteins in ACC tumors. This evidence concerns the gene MYBL1 and adrenal cortex carcinoma.
