•DNA methylation is an important epigenetic mechanism regulating gene expression.•DNA methyltransferases add repressing or activating methyl “marks” to DNA.•Ten-eleven translocation enzymes help to remove methyl marks from DNA.•DNA methyltransferase and ten-eleven translocation genes play key roles during normal and pathologic hematopoiesis.
DNA methylation is an important epigenetic modification that can have profound and widespread effects on gene expression and on cellular fate and function. Recent work has indicated that DNA methylation plays a critical role in hematopoietic development and hematopoietic disease. DNA methyltransferases and Ten-eleven translocation enzymes are required to add and remove methyl “marks” from DNA, respectively, and both sets of genes have been found necessary for proper formation and maintenance of hematopoietic stem cells and for differentiation of downstream hematopoietic lineages during development. DNA methylation and demethylation enzymes have also been implicated in hematopoietic disorders such as acute myeloid leukemia and myelodysplastic syndrome. Here, we review some of the recent literature regarding the role of DNA methylation in hematopoietic health and disease.
