Acetylation of histones by lysine acetyltransferases (KATs) is essential for chromatin organization and function. The MYST family of KATs (KAT5-8) includes the oncogenes KAT6A (MOZ) and KAT6B (MORF/QKF). KAT6A has essential roles in normal hematopoietic stem cells and is the target of recurrent chromosomal translocations, causing acute myeloid leukemia. Similarly, chromosomal translocations in KAT6B have been identified in diverse cancers. KAT6A suppresses cellular senescence via regulation of suppressors of the CDKN2A locus, a function that requires its KAT activity. Loss of one allele of KAT6A extends the median survival of mice with MYC-induced lymphoma from 105 to 413 days. These findings suggest that inhibition of KAT6A and KAT6B may provide a therapeutic benefit in cancer. We have produced a series of highly potent, selective inhibitors of KAT6A/B including WM-8014 and WM-1119, which we anticipate will be useul in accelerating development of therapeutics. For comparison purposes, we also generated an inactive analogue WM-2474 as a control treatment. The data here focus on WM-2474 and present RNA-seq profiling of mouse embryonic fibroblasts (MEFs) treated with either WM-2472 or DMSO.
