Here we investigate the role of epigenetics in the formation, transcription regulation, maintenance and termination of several non-canonical chromatin structures. Using two examples, we demonstrate how studying non-canonical structures may reveal underlying mechanisms with implications for disease and propose intriguing epigenetic avenues for further exploration. Human DNA, approximately 3 billion base pairs in length, is organized into chromosomes.

AbstractChromosomal instability (CIN) and epigenetic alterations are characteristics of advanced and metastatic cancers1,2,3,4, but whether they are mechanistically linked is unknown. Here we show that missegregation of mitotic chromosomes, their sequestration in micronuclei5,6 and subsequent rupture of the micronuclear envelope7 profoundly disrupt normal histone post-translational modifications (PTMs), a phenomenon conserved across humans and mice, as well as in cancer and non-transformed cells.
