Epigenetic signals are responsible for the establishment, maintenance and reversal of metastable transcriptional states that are fundamental for the cell's ability to “remember” past events, such as changes in the external environment or developmental cues. Complex epigenetic states are orchestrated by several converging and reinforcing signals, including transcription factors, non-coding RNAs, DNA methylation, and histone modifications. Although all these pathways modulate transcription from chromatin in vivo, the mechanisms by which epigenetic information is transmitted through cell division remain unclear. Because epigenetic states are metastable and change in response to the appropriate signals, a deeper understanding of their molecular framework will allow us to tackle the dysregulation of epigenetics in disease.
