Specifically, it puts emphasis on the regulation of gene expression, through DNA methylation, chromatin, and posttranslational modification of proteins such as histones. Arrows indicate possible functional interactions between them. DNA hypermethylation, histone hypoacetylation and inactive chromatin repress transcription. In contrast, a transcriptionally active condition may encourage DNA hypomethylation, histone hyperacetylation and active chr
