Drug That 'Tags' Decision-making Areas Of The Brain May Aid
Along with aiding efforts to study addictedsmokers, a new drug that attaches only to areas of the brain that havebeen implicated in may help studies of people battling other disorders such as Alzheimer’sdisease and schizophrenia.Developed by UC Irvine Transdisciplinary Tobacco Use Research Centers...50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel
Researchers at the University of Chicago have found that a recently discovered biological process known as sumoylation -- until now thought to be active only in the nucleus -- also occurs near the cell's surface where it regulates at least one and possibly many kinds of proteins, providing a novel target for the development of new drugs. The discovery, published in the 8 April 2005 issue o...Hopkins scientists uncover 'tags' that force proteins to cell surface
Discovery likely to streamline drug and vaccine development Johns Hopkins scientists have discovered internal "shipping labels" that allow -- and perhaps force -- hundreds if not thousands of proteins to get to the surface of cells and stay there. Two natural proteins that use one of these "tags" are the ion channel that lets heart cells contract on cue, and the docking point that allows...High-tech tags on marine animals yield valuable data for biologists and oceanographers
Researchers are enlisting seals, sea lions, tunas, and sharks to serve as ocean sensors, outfitting these top predators with electronic tags that gather detailed reports on oceanographic conditions and, in many cases, transmit the data via satellite. The data are proving useful to both biologists and oceanographers, yielding new information about the migrations and behavior of the animals and abo...
