Gene-Altered Mouse May Provide New Insights To Parkinson's Disease, Substance Abuse And Schizophrenia
...e, said Caron. The mouse research maypoint the way toward
drugs that maintain the higher levels of dopamine inthe brains of Parkinson's sufferers. In Parkinson's disease, dopamine-producing neurons in the brain's motorcontrol center, called the substantia nigra, slowly deteriorate and die.Thus, Parkinson'...
New Cancer Switch Discovered By Duke Medical Center Pharmacologists
...ntists in October and November, all of which point toward
new ways to interfere with the malignant machinery of cancer cells to kill them. In a second paper in the October issue of Molecular and Cellular Biology, the scientists reported new understanding of how cancer cells acquire the ability to avoid the ...
New 'Twist' In Proteins Offers Possible Route To Improved Antibiotics
...e of its bound substrates. In a first step toward
developing antibiotics that would block the enzyme'sactivity, the Duke scientists also are planning to survey known chemicalsthat might fit into the cleft of the active site. "Conceptually, it would seem feasible to design drugs that could a...
Computer Program For Quicker, More Detailed Mapping

Fast Measurement Technique Reveals Early Steps In Protein Folding
...anding how proteins fold is a necessary first step toward
the eventualgoal of tailoring designed proteins. But, to study how proteins fold, researchersfirst must unfold them. Gruebele and his colleagues -- graduate students Richard Ballew and JobiahSabelko -- do this by supercooling the proteins in an aqu...
