SRP212620 PRJNA551672 GSE133516 KAT7 maintains myeloid leukemogenesis recruits BRD4 to the promoters of target loci to maintain then MLL-AF9 transcriptional programme Here we investigate the essentiality of lysine acetyltransferase KAT7 in AMLs driven by the MLL-X fusions. We find that KAT7 activity is required for the recruitment of the MLL-fusion associated adaptor proteins such as BRD4 to gene promoters, which are critical for the maintenance of the MLL-AF9 transcriptional programme. Our findings propose that KAT7 is a plausible therapeutic target for this poor prognosis subtype of AML. Overall design: Study KAT7 binding and the effects of its knockout on the transcriptome in MOLM13 and OCIAML3 cell lines GSE133516 pubmed 32764680
