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 E?-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
development. Hence, B-cell progenitor numbers were significantly reduced in Moz
haploinsufficient animals. Interestingly, we find a significant overlap in genes
regulated by MOZ, mixed lineage leukemia 1, and mixed lineage leukemia 1 cofactor
menin. This includes Meis1, a TALE class homeobox transcription factor required
for B-cell development, characteristically upregulated as a result of MLL1
translocations in leukemia. We demonstrate that MOZ localizes to the Meis1 locus
in pre-B-cells and maintains Meis1 expression. Our results suggest that even
partial inhibition of MOZ may reduce the proliferative capacity of MEIS1, and
HOX-driven lymphoma and leukemia cells.
