[Molecular mechanisms involved in epigenetic alterations in cancer].

Abstract excerpt

Epigenetic alterations such as DNA methylation and histone modification play a role in gene silencing in tumorigenesis. DNA methylation affects the expression of genes involved in cell cycle checkpoint, apoptosis, and DNA repair. Recently, epigenetic alterations are shown to play a role in silencing microRNA. Mutations of DNA methyltransferase and histone modification enzymes such as DNMT3A, UTX and EZH2 have...
