Not all genes are active at all times. DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression. This straightforward experiment demonstrated that it was not ...

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 ...

Inside each cell of the human body are proteins that control which genes are expressed at the right place and time. However, intriguingly, many of the most important proteins involved in gene ...

Turning genes on and off is like flipping a light switch, controlling whether genes in a cell are active. When a gene is turned on, the production of proteins or other substances is promoted; when ...

Mice and newts were applied to the one-step Cre-loxP organism creation technology by TAx9. In this study, the researchers succeeded in synthesizing a Cre-loxP integrated vector by placing a short DNA ...

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 ...
