Abstract:

In eukaryotes,as a common mechanism of epigenetic regulation,DNA and histone methylations mainly affect chromatin structure and gene transcription expression,especially in gene expression regulation of mammalian cells and maintaining genome stability. This paper reviews DNA methylation modification and its role in gene expression regulation,gene expression regulation mode,function and research progress of histone methylation modification,as well as the interaction between DNA and histone methylations in epigenetic regulation.

Key words: gene expression, epigenetic regulation, DNA methylation, histone methylation
