title: Epigenetics in gastric carcinogenesis: TET genes as important players.
abstract: Epigenetic processes including aberrant promoter methylation of tumor suppressor gene play a key role in gastric carcinogenesis. TET proteins are involved in DNA demethylation; many cancers, haematological or solid, present loss-of-function mutations and aberrant expression/regulation of TET. In gastric cancer there are few studies reporting a decreased expression of TET and associations between these proteins and signaling pathways involved in carcinogenesis. Identifying connections between aberrant expression of TET, disruption of the balance between DNA methylation and demethylation and their association with gastric carcinogenesis might be useful for the development of novel therapeutic approaches.
