Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntingtons disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the disease.
HD is a devastating, inherited, neurodegenerative disease that is progressive and always fatal. The disease-causing gene produces a protein that is toxic to certain brain cells, and the subsequent neuronal damage leads to the movement disorders, psychiatric disturbances and cognitive decline that characterize this disease.
"Many of the current approaches aimed at treating HD are indirect and target the symptoms of the disease. RNA interference gives us the first opportunity to attack the fundamental problem and reduce protein expression from the disease gene," said Beverly L. Davidson, Ph.D., the Roy J. Carver Chair in Internal Medicine and UI professor of internal medicine, physiology and biophysics, and neurology. "Our study is the first demonstration that a therapy designed to inhibit protein production has a beneficial effect."

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
