Pathway discovered to influence fat accumulation

admin — Mon, 02 Jul 2007 20:01:39 -0400

In a remarkable breakthrough for weight research, scientists have reported the discovery of a neurochemical pathway that stimulates the accumulation of fat in animals laboring under chronically high stress and exposed to a diet of junk food. Inhibiting the pathway prevented weight gain in mice but selectively spurring the mechanism allowed for the strategic accumulation of weight--potentially opening a new pathway to mold larger breasts, firmer buttocks and younger faces.

New drug controls body's signals for eating

admin — Mon, 11 Jun 2007 20:01:39 -0400

A research team at Hebrew University on Jerusalem has developed a drug that mimics the activity of the hormone aMSH, which spurs the feeling of fullness. The hormone binds to a receptor in the brain that sends out the signal to the body that it is full. The researchers, led by a grad student, developed a synthetic peptide called BL-3020 that was able to enter the bloodstream, make its way to the receptor and emit the 'full' signal. Testing the therapy on mice over 24 hours, researchers …

Gene deletion study defuses disease risk from fat

admin — Mon, 07 May 2007 20:01:39 -0400

A new study in mice raises the possibility that humans may one day be able to eat any kind of fat they want without raising their risk of heart disease. The study involved deleting a gene in the mice that causes production of ACAT2, an enzyme that alters the molecular structure of cholesterol so that it can be transported to the body's cells.

"We deleted an enzyme in mice and they could eat any type of fat and not get heart disease," said Lawrence Rudel, Ph.D., a professor of …

Drug switches on fat-burning gene in mice

admin — Mon, 30 Apr 2007 20:01:39 -0400

Ronald M. Evans, an investigator at The Salk Institute in San Diego, has developed a drug that switches on the PPAR-d gene in mice, protecting them against weight gain from high-calorie and high-fat diets. The drug--which mimics fat--triggers their metabolisms and generates a physical response similar to exercising. After treatment, the mice had lower levels of fatty acids, triglyceride and sugar levels. These mice also exhibited much greater stamina, allowing them to exercise twice as …
