How the hat fits: Structural biology study reveals shape of epigenetic enzyme complex

— 21 Jan 2011 20:32 | Biology

To 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 | Health

UCSF 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 | Health

The 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…

Penn study on skin formation suggests strategies to fight skin cancer

— 7 Dec 2010 17:22 | Health

In a study published in the journal Developmental Cell, Sarah Millar PhD, professor of Dermatology and Cell and Developmental Biology at the University of Pennsylvania School of Medicine,…

UNC-led team tests commonly used antibodies

— 6 Dec 2010 18:18 | Health

If 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 | Biology

The 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 | Health

Like 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 | Health

By 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…

Stress can control our genes

— 25 Sep 2010 12:05 | Health

Stress has become one of the major disease states in the developed world. But what is stress? It depends on from where you look. You may experience stress as something that affects…

At the crossroads of chromosomes

— 18 Sep 2010 08:34 | Health

On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication can lead…
