New signaling systems discovered in human cells

The human cell has a wide variety of receptors on its surface that many molecules and therapeutic drugs can bind to in order to activate signals inside the cell to regulate different physiological functions. GPCRs are the largest - and a very important - family of receptors on human cells.

Mutated version of DNA repair protein may illuminate its role in preventing cancer

Two trillion times each day, the cells in a typical human divide to replace old, damaged or dead cells. Before a cell divides, though, it makes an exact copy of its DNA, which will be passed on to the new cells.

Mechanisms preserving cell identity are based on status of proteins housing DNA

The inheritance, not only of DNA, but of changes to proteins that package it, maintains the identity of cells as they multiply, a new study finds.

Scientists identify protein that pulls the brake on nerve growth

During embryonic development, nerve cells form thin, long extensions, which they use to wire up a complex network, the brain. Scientists from the German Center for Neurodegenerative Diseases in Bonn have now identified a protein that regulates the growth of these extensions by pulling a brake.

Researchers reconstruct the evolutionary history of metabolism

By analyzing how metabolic enzymes are built and organized, researchers have reconstructed the evolutionary history of metabolism. Their study shows how metabolic networks - which drive every cellular process from protein building to DNA repair - became less random, more modular and more hierarchical over time, the researchers say.

Nerve cell protection without side effects on erythropoiesis

The hormone erythropoietin (Epo) is a well-known doping substance that has a long history of abuse in endurance sports, such as cycling. In addition to promoting red blood cell production (erythropoiesis), which improves the oxygen supply in the organism, Epo also protects nerve cells from cell death.

White and brown fat cells send very different signals to rest of the body

Many people might not realize that they have different types of body fat. Most of it is white fat that sits on your stomach, hips and thighs, for example. White fat is an energy storage that our body can use when food is scarce.
