Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
