Abstract:
Epigenetics, a combination of DNA modifications, chromatin organization, and variations in its associated proteins, configure a new entity that regulates gene expression throughout methylation, acetylation, and chromatin remodeling. In addition to silencing as a result of mutations, loss of heterozygosity, or classical genetic events epigenetic modification symbolizes essential early events during carcinogenesis and tumor development. The reversion of these epigenetic processes restoring normal expression of tumor-suppressor genes has consequently become a new therapeutic target in cancer treatment. Aberrant patterns of epigenetic modifications will be, in a near future, crucial parameters in cancer diagnosis and prognosis.
