ATAC-seq peaks indicating chromatin accessibility regions upstream the TCF4 locus in MM057 control cells (DMSO) and following exposure to the BET-inhibitor ARV-771. The ATAC-seq profiles of untreated MM099 and of two melanocytic MM lines (MM001 and MM011), which were previously described, are also shown. The previously described BRD4 binding site is highlighted in the red rectangle.
