Abstract:
Genetic studies of epigenetic modifiers such as DNA methyltransferases and histone acetyltransferases have revealed a critical role for epigenetic regulation during brain development and function. Alteration of epigenetic modifications have been documented in a variety of brain disorders, including neurodevelopmental, psychiatric, and neurodegenerative diseases. Development of epigenome editing tools enables a functional dissection of the link between altered epigenetic changes and disease outcomes. Here, we review the development of epigenome editing tools, summarize proof of concept applications focusing on brain disease-associated genes, and discuss the promising application and challenges of epigenome editing to tackle brain disorders.
