Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...
Scientists at the MRC Laboratory of Medical Sciences (LMS) have discovered a DNA-based “dimmer switch” that regulates the activity of a critical developmental gene, Cdx2. This work could pave the way ...
Molecular biologists have long believed that the beginning of a gene launched the process of transcription—the process by ...
A figure from the paper illustates a key finding of "compromised compartmentalization": chromatin that was locking genes down in health became more open in Alzheimer's, while chromatin that was open ...
