Cause of stress-related DNA damage pinpointed: Findings suggest new model for developing novel therapeutic approaches

Posted: 22 Aug 2011 12:10 PM PDT

Sscientists have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

Genetic markers show something fishy with certified Chilean sea bass sales

Posted: 22 Aug 2011 10:18 AM PDT

A population biologist has found that not all certified Chilean sea bass are what they are claimed to be. Some fish sold in stores are not from the fishing grounds certified as sustainable, and some are not Chilean sea bass at all.

Fat signals: Lipid cleaving enzyme produces signaling molecule essential in lipid metabolism

Posted: 22 Aug 2011 06:16 AM PDT

Normal lipid and energy metabolism requires complex regulation by a network of signaling processes. Researchers now show that mice that lack the fat cleaving enzyme ATGL cannot produce signaling molecules needed to regulate nuclear receptors. As a consequence, mitochondria, the power plants of the cells, fail to function properly in these animals. The findings provide a promising therapeutic strategy for patients suffering from Neutral Lipid Storage Disease (NLSD).

Iberian lynx not doomed by its genetics

The low genetic diversity of the Iberian lynx -- the most endangered carnivore in Europe -- may not decrease the species' chance of survival, according to new research by geneticists.

At last, a reason why stress causes DNA damage

Posted: 21 Aug 2011 11:11 AM PDT

For years, researchers have published papers that associate chronic stress with chromosomal damage. Now researchers have discovered a mechanism that helps to explain the stress response in terms of DNA damage.
