For instance one study in a Rhabdomyosarcoma cell line, has shown that both the CE and the Myod TSS region are nucleosome free, and are associated with high levels of H3K4me1 and H3K4me3 respectively, while in colorectal cancer cells, where Myod is not expressed, both the CE and promoter contain nucleosomes (Table 2; Taberlay et al. 2011). Here, MYOD1 is linked to rhabdomyosarcoma.
