Epigenetic mechanisms are increasingly considered major factors contributing to MB pathogenesis. Particularly, dysregulation of epigenetic/chromatin mod- ifiers, including histone acetylation/methylation marks, is very common in in Group 3 and Group 4 MBs, com- pared with other subgroups. Histone acetylation marks play important roles in regulating gene transcription, including transcription of MYC oncogene. These marks are written by histone acetyltransferases (HATs), erased by histone deacetylases (HDACs) and read by bromodomain extra-terminal (BET) proteins. Importantly, HDACs and BET proteins have been shown to regulate MYC transcription and its associated tumori-genic programs, making them rational targets for MYC-driven MB therapy.
