Penn Researchers Find a New Role for a 'Foxy Old Gene'
August 1, 2008
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called FOXA2 controls genes that maintain the proper level of bile in the liver. FOXA2 may become the focus for new therapies to treat diseases that involve the regulation of bile salts. The study was published online this week in Nature Medicine.

Searching for Shut Eye: Penn Study Identifies Possible Sleep Gene
July 29, 2008
While scientists and physicians know what happens if you don’t get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit flies. In a recent study of fruit flies, they identified a gene that controls sleep.

Detecting Alzheimer’s Disease Earlier: Penn Researchers Identify Promising Indicators
July 28, 2008
Researchers from the University of Pennsylvania School of Medicine have identified two new techniques to detect the progression of Alzheimer’s disease earlier. By catching Alzheimer’s disease before symptoms are apparent, physicians can prescribe treatments to slow down the disease progression. In one study, researchers identified abnormal structural changes in the brains of seemingly normal elderly that indicated mild cognitive impairment, a precursor to Alzheimer’s disease. In a second study, researchers detected changes in cells that may help predict the transition from mild cognitive impairment to Alzheimer’s disease.
