Epigenetic mechanisms such as DNA methylation and histone modifications drive stable, clonally propagated changes in genes expression and can therefore serve as molecular mediators of pathway dysfunction in neoplasia. MDS is characterized by frequent epigenetic abnormalities, including the hypermethylation of genes that control proliferation, adhesion, and other characteristic features of this leukemia. Aberrant DNA hypermethylation is associated with a poor prognosis in MDS that can be accounted for by more rapid progression to AML. In turn, treatment with drugs that modify epigenetic pathways (DNA methylation and histone deacetylation inhibitors) induce durable remissions and prolong life in MDS, offering some hope and direction in the future management of this deadly disease.
