Beta arrestins found to generate new proteins

Duke University Medical Center researchers have recently discovered that a crucial communications pathway in cells not only stops cells from making proteins, it also makes them go. The team was able to define the way in which proteins called beta arrestins (for their role in stopping signals) also turn on pathways that ultimately lead to the production of new proteins in virtually all tissues in the body.

Metabolic genes tied to inflammatory predictor of heart disease and stroke risk

Two new studies provide evidence that differences in people's blood levels of C reactive protein (CRP) stem in part from natural variation in known metabolic genes. The researchers report their findings in the May American Journal of Human Genetics, a publication of Cell Press.
