There is more to losing weight than diet and exercise, according to investigators the Research Institute at the McGill University Health Centre (MUHC). Their study is the first to identify a new receptor protein present on fat cells that may play a role in fat metabolism. The findings, published recently in the Journal of Biological Chemistry, have implications for the many individuals suffering from obesity.
"We have identified a receptor protein on fat cells that when stimulated may increase the amount of lipid stored in fat reservoirs," says MUHC researcher Dr. Katherine Cianflone. "This protein, C5L2, is made by fat tissue, is on the surface of fat cells and binds a specific hormone to increase fat production."
Cianflone, an Associate Professor at McGill University, with colleagues from McGill University and the United Kingdom characterized the binding activities of C5L2. They showed that this protein is a cell surface receptor that binds acylation stimulating protein (ASP), a protein known to affect fat production.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
