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 ...

The expression of genes has to be carefully regulated in cells; active genes give cells their identity and ability to function. Epigenetic features are just one way that cells control gene expression, ...

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 which a segment of DNA is copied into RNA and then RNA helps make the proteins ...

An innovative CRISPR-Cas12f-based activator system may hold significant potential in the future of gene therapy and biological research, suggest researchers of a new study. The study highlights the ...

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 ...

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 ...
