Duke team finds compounds that prevent nerve damage

EurekAlert! - Chemistry, Physics and Materials Sciences  Mon, 09/22/2008 - 23:00

(Duke University Medical Center) Duke University Medical Center scientists have made a significant finding that could lead to better drugs for several degenerative diseases including Huntington's disease and Alzheimer's disease.

Compounds that block the activity of a specific enzyme prevented brain injury and greatly improved survival in fruit flies that had the same disease process found in Huntington's disease.

EurekAlert! - Chemistry, Physics and Materials Sciences  Wed, 05/21/2008 - 23:00

(Duke University Medical Center) Researchers at Duke University Medical Center have published a study in Science that provides compelling evidence that the nitric oxide system in cells is very broad-based and important, resembling in its essence the much-studied system of phosphorylation.

The findings may offer new insights into how cells work and the basis of many diseases.
