How the hat fits: Structural biology study reveals shape of epigenetic enzyme complex
— 21 Jan 2011 20:32 | BiologyTo understand the emerging science of epigenetics - a field that describes how genes may be regulated without altering the underlying DNA itself - scientists are deciphering the many…
UCSF team views genome as it turns on and off inside cells
— 20 Jan 2011 17:10 | HealthUCSF researchers have developed a new approach to decoding the vast information embedded in an organism's genome, while shedding light on exactly how cells interpret their genetic material…
Tools used to decipher 'histone code' may be faulty
— 18 Dec 2010 13:57 | HealthThe function of histones - the proteins that enable yards of DNA to be crammed into a single cell - depends on a number of chemical tags adorning their exterior. This sophisticated…

UNC-led team tests commonly used antibodies
— 6 Dec 2010 18:18 | HealthIf a strand of your DNA was stretched out completely, it would be more than six feet long. It's hard to imagine that it can fit inside the nucleus of one of your cells, but that's exactly…
On the trail of the epigenetic code
— 13 Oct 2010 16:30 | BiologyThe genetic inherited material DNA was long viewed as the sole bearer of hereditary information. The function of its packaging proteins, the histones, was believed to be exclusively…
Ticking of cellular clock promotes seismic changes in the chromatin landscape associated with ageing
— 4 Oct 2010 08:14 | HealthLike cats, human cells have a finite number of lives-once they divide a certain number of times (thankfully, more than nine) they change shape, slow their pace, and eventually stop…
Epigenomics discovery yields new information about fat cells
— 1 Oct 2010 10:27 | HealthBy creating a 'map' of histone modifications in fat cells, investigators have discovered two new factors that regulate fat formation, a key step on the road to better understanding…
