Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

Very low LDL cholesterol levels appear to be safe for heart patients on statin therapies

"There was no apparent safety concern for patients whose resultant LDL on intensive therapy was lower than current guidelines. There was a trend toward improved clinical outcomes in the lowest LDL groups," said Stephen D. Wiviott, M.D., from Brigham and Women's Hospital in Boston, Massachusetts.

New discoveries help explore the function of regulatory T cells in autoimmune disease and in cancer

More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.

Real-world treatment of patients with acute coronary syndromes

A review of more than 56,000 cases of acute coronary syndromes reveals that older patients are less likely to receive treatment recommended by guidelines, even though they benefit as much or more than younger patients when the recommended treatment is provided, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.

Defibrillator implantations performed by physicians with low volume are more likely to have adverse outcomes

As the implantation of cardioverter-defibrillator devices to prevent sudden cardiac death becomes increasingly popular, patients are likely to get the best results when they are treated by physicians who perform the procedures frequently, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.
