Transcription of the Myc gene was reduced after BRD9 inhibition, in line with prior results in murine and human AML cell lines (refs. 4, 5; Fig. 5; Supplementary Fig. S7, red tracks); however, BAF subunit binding was unchanged at the Myc promoter, supporting a mechanism of gene-distal regulation by ncBAF. Here, MYC is linked to acute myeloid leukemia.
