DNA methylation is an epigenetic modification that contributes to essential biological processes such as retrotransposon silencing, cell differentiation, genomic imprinting and X-chromosome inactivation. DNA methylation generates a stable epigenetic mark associated with silencing of gene expression. Aberrant DNA methylation is associated with the development of different tumor types. Reversing DNA methylation is a rational strategy to restore gene re-expression and induce cell differentiation in cancer. DNA hypomethylating agents is a class of drugs that demonstrated efficacy in different tumors. In this chapter, the classification of DNA hypomethylating agents, their pharmacodynamics and their potential drawbacks will be discussed.
