Gene repression can be sex-specific

Researchers have shown for the first time that embryonic cells destined to become either egg or sperm rely on different methods of repressive gene regulation.

A histone modification essential for tissue integrity

Chemical modifications of histones, the small proteins around which DNA is wrapped, are known to affect gene expression. In a study conducted in C. elegans, researchers from the Gasser group show that the defining modification ...

How to turn specific genes on and off

All the cells in an individual's body bear the same genetic code. It is the reading and writing of this code—the "turning on" and "turning off" of specific genes in specific cells—that gives the cells their identities. ...

There's more to genes than DNA: How Mum and Dad add something extra

Biologists at the Universities of Bath and Vienna have discovered 71 new 'imprinted' genes in the mouse genome, a finding that takes them a step closer to unraveling some of the mysteries of epigenetics—an area of science ...
