A study in The Journal of Biological Chemistry provides what the authors say is proof of concept that dying photoreceptors can be rescued by cell transplantation.

Two new studies on oral bacterium that causes lethal heart valve infection


Two back-to-back studies published in The Journal of Biological Chemistry have provided significant insights into virulence of Streptococcus sanguinis, which causes a potentially lethal infection of heart valves.

Realizing when proteins go bad


In the journal Molecular & Cellular Proteomics, researchers report that changes in two major blood proteins, considered by some scientists to be signs of cardiovascular disease, actually correlate with improper handling and storage.

A critical lipoprotein receptor reduces metabolic disorders brought on by low testosterone


In a paper in the Journal of Lipid Research, investigators demonstrate that the effects of testosterone on metabolism may be altered by the low-density lipoprotein receptor, a critical protein for the transport of lipid-modified proteins and the regulation of blood cholesterol levels.
