Better Therapies For Cardiovascular Disease May Be Product Of Protein Tug Of War

Two proteins are in a tug of war that determines how much the body makes of superoxide, a highly reactive and potentially destructive product of oxygen that's dramatically elevated in cardiovascular disease, researchers report. Their finding indicates an antiulcer drug just may help the body reduce excessive levels. Hsp90 and Hsp70 are both heat shock proteins but appear to have opposite effects on reactive oxygen species production, said Dr. David J.R. Fulton, Interim Director of the Vascular Biology Center at the Medical College of Georgia at Georgia Health Sciences University...
