DNMT3A and acute myeloid leukemia: For example, miR‐29b has been shown to be deregulated in AML and directly targets DNA methyltransferases, DNMT3A and 3B.[[qv: 5b]],[[qv: 7b]] Although the bulk population transfected with either miR‐29b synthetic mimic molecules or miR‐29b expression plasmid showed decreased level of DNMT3A and 3B, there is no evidence to show the direct correlation between miR‐29b and DNMT3A and 3B in a single cell.
