The Role of Oxidative Stress and Apoptosis in the Pathogenesis of Heart Failure

Apoptotic cell death has been implicated in cardiovascular pathologies such as congestive heart failure, myocardial ischemia, cardiomyopathy and atherogenesis. A growing body of literature suggests apoptosis induced by oxidative stress plays a key role in the pathogenesis of heart failure. Our preliminary results suggest that there is increased expression of antiapoptotic Bcl-2 proteins and decreased expression of antiapoptotic protein Mcl-1 in ischemic heart disease patients as compared to the control group. This increase in Bcl-2 expression is accompanied by a decrease in expression of proapoptotic Bax proteins when compared to controls. We believe that irrespective of proapoptotic or antiapoptotic protein influences, the ratio of Bcl-2/Bax proteins plays a major role in determining c... view moreĀ»
