Tumorigenesis is traditionally thought to be caused by the imbalance between oncogenes and tumor-suppressor genes. Epigenetics is a recently described phenomenon that uses an alternative mechanism to explain the transcriptional inactivation of tumor-suppressor genes predominantly by hypermethylation of the promoter regions. Hypermethylation of these regions has been described extensively in many neoplasms, including cutaneous melanoma. Histone modification, primarily by acetylation and deacetylation, is a current potential target for melanoma therapy, but more research is required to understand the mechanisms involved and the therapeutic effectiveness of regimens involving these agents. These mechanisms not only are important for understanding the origin and progression of neoplasms but also have important potential therapeutic implications. Understanding the epigenetic mechanisms involved in melanoma can provide valuable information with significant implications in diagnosis, treatment, and prevention.
