Abstract

The histone acetyltransferase MOZ (MYST3, KAT6A) is the target of recurrent chromosomal translocations fusing the MOZ gene to CBP, p300, NCOA3, or TIF2 in particularly aggressive cases of acute myeloid leukemia. In this study, we report the role of wild-type MOZ in regulating B-cell progenitor proliferation and hematopoietic malignancy. In the Eμ-Myc model of aggressive pre-B/B-cell lymphoma, the loss of just one allele of Moz increased the median survival of mice by 3.9-fold. MOZ was required to maintain the proliferative capacity of B-cell progenitors, even in the presence of c-MYC overexpression, by directly maintaining the transcriptional activity of genes required for normal B-cell deve..
