The past few decades have seen a revolution in the understanding of mechanisms of epigenetic inheritance - the passing on from one generation of cells to another of information that affects phenotype but does not alter the actual DNA sequence. One of the longest known epigenetic modifications is the methylation of cytosines in DNA which is typical of organisms with large genomes whose cells undergo many divisions over the organism s lifetime. In recent years the realization that inappropriate methylation of promoters of tumor suppressor genes may contribute to oncogenesis has sparked renewed interest in DNA methylation. Despite many years of work however how changes in DNA methylation status occur during normal cell differentiation and whether these changes have a role in regulating gene expression still remain unclear. .
