A new type of epigenetic regulation

Research conducted by a Swiss team and Anna Mattout of the LBCMCP shows for the first time that there is, in the worm, another level of post-transcriptional regulation, which specifically degrades RNA from heterochromatin. In addition to a better general understanding of post-transcriptional regulation, this discovery opens up therapeutic possibilities from a completely new angle in various pathologies, particularly cancer. This study was recently published in Nature Cell Biology.
