Structural data reveals key aspects of function Professor Jan Breslow and colleagues, including biomedical fellow Raymond Soccio, recently discovered a novel subfamily of the START domain lipid transfer proteins, which are thought to shuttle lipids such as cholesterol within cells. In addition, ...

A killer protein named Reaper. A protective protein in bits and pieces. And a dead cell. This is the scene of one of the body's most perfect crimes: programmed cell death. This vital process occurs throughout life as a means to, among other purposes, eliminate potentially cancerous cells. Now, by...

Researchers identify a key ingredient in development of body fat The future of a young body cell is filled with uncertainties. Will it mature into a red blood cell and carry oxygen to remote tissues? Or might it become a liver cell and help rid the body of dangerous toxins? Ultimately, its destin...

The first three-dimensional images of the initiating form of the molecular machinery in bacteria that "transcribes" genetic information from DNA into RNA — the crucial first step for making proteins — is reported in a pair of papers in the May 17 issue of the journal Science. These research fin...

Rockefeller scientists redefine role of proteins responsible for bundling DNA into cells Histones, the proteins that help roll several feet of DNA into the microscopic span of a single nucleus, are turning out to be much more than just packaging material. Instead, recent studies indicate that the...

Diversity in PKC signaling enzymes yields clues to tolerance The difference between good and evil matters as much in the immune system, it turns out, as it does to humankind. The problem is understanding how the immune system's cells perceive the difference. In the April 25 issue of the journal N...

Possible insight to multiple sclerosis and other neurodegenerative diseases that destroy nerve cell "insulation" In the May 3 issue ofÌýScience, scientists at Rockefeller University and New York University School of Medicine report that the nerve damage that leads to a loss of sensation and disab...

Brain opiate may explain why some people are less susceptible to addiction Some people's brains may harbor their own built-in defense system against the addictive powers of cocaine. According to new research at ÐÓ°É, a naturally occurring brain opiate called dynorphin may, i...

Loss of protection at tips of chromosomes may explain why older cells cease to reproduce As we grow older, our hair turns gray, our bones grow thin and, among other changes, our telomeres shrink. But, more than markers of the passage of time, telomeres, the tips of chromosomes, may harbor answers...

In a systematic study of 13 genes on human chromosome 22 in an area of the chromosome previously linked to schizophrenia, a team of scientists in the United States and South Africa identified two genes from this group that contribute to susceptibility to this psychiatric disorder. The report, pub...
