DNA Methylation in Cancer and Aging

DNA methylation is known to be abnormal in all forms of cancer, but it is not really understood how this occurs and what is its role in tumorigenesis. In this review, we take a wide view of this problem by analyzing the strategies involved in setting up normal DNA methylation patterns and understanding how this stable epigenetic mark works to prevent gene activation during development. Aberrant DNA methylation in cancer can be generated either prior to or following cell transformation through mutations. Increasing evidence suggests, however, that most methylation changes are generated in a programmed manner and occur in a subpopulation of tissue cells during normal aging, probably predisposing them for…
