Messing With Your Head: Cocaine Found to Affect Endorphin Gene in Brain
The effects of the addictive drug cocaine result, in part, from altering the activity of a gene in the brain, report scientists from The Rockefeller University in the May Molecular Brain Research. "Our study is the first report that any drug of abuse, in this case cocaine, alters the expression o...
Low Fat, High Sugar Diets Prompt Production of Saturated Fats
Eating a low-fat diet may not always be as healthy as people wish. Results from a study, reported in the May 1 The Journal of Clinical Investigation by scientists at The Rockefeller University and the University of California, Berkeley, show that people on weight-maintenance diets low in fat bu...
Gene Involved in Brain Development Identified
Astrotactin is a Nerve's Ticket to Ride the Glial Highway Scientists from The Rockefeller University and the Howard Hughes Medical Institute (HHMI) have for the first time identified a gene involved in directing nerve cells to their destinations as the brain grows. Their work appears in the April...
Mucosal Tissue Site of AIDS Virus Replication in Clinically Well HIV-Infected People
Virus appears to continuously replicate in tissues other than the lymph system The mucous membranes that lie above the lymph glands of the throat can be a major site of HIV-1 replication in people infected with the virus that causes AIDS but who have not yet developed clinical symptoms, report sc...
Light Sets the Molecular Controls of Circadian Rhythm
Light sets the circadian rhythm by eliminating a key protein needed for the molecular mechanism of the body's clock, according to scientists in the March 22 Science. The findings, from fruit fly studies, may help explain light's effect on the daily cycle that influences sleep, mental alertness, p...

Cells Leap Frog On The Way To Becoming Nerve Cells
Clues to movement may help design therapies for diseased, injured brains. Kids aren't the only ones who play Leap Frog. Cells destined to become nerves in the brain do too, according to scientists from The Rockefeller University, who published their findings in the Feb. 16 Science. The informatio...
Genes in Overweight Mice, Rats Carry Instructions for Leptin Receptor
The diabetes (db) gene in mice and the fatty (fa) gene in rats are not only the same genes, they also carry instructions to make the receptor for the protein called leptin, which is known to signal the body's fat, report scientists at The Rockefeller University and Millennium Pharmaceuticals Inc...
Mutations in a Leptin Receptor Cause Obesity in Mice
The weight-reducing effects of leptin, a hormone that signals the size of the body's fat stores, result from an interaction with a receptor in the brain's hypothalamus, report scientists from the Howard Hughes Medical Institute (HHMI) at The Rockefeller University in the Feb. 15 Nature. "When we...
