Grant number: 300013

Abstract

In Australia, coronary heart disease (CHD) leading to heart attacks or strokes is the largest cause of death, claiming a staggering 28,000 lives a year. Oxidative stress, resulting from increased production of oxygen free radicals in arteries, appears to be an important cause of CHD, heart attacks and strokes. We seek to understand how such oxyradicals are produced in the cells that make up the artery wall. Using novel DNA-type molecules we have recently discovered that a protein called Nox4 is crucial for the production of oxygen free radicals by blood vessels. Furthermore, we have identified a class of drugs that selectively block the activity of Nox4 in blood vessels. We now wish to direc..
