Zinc-mediated reduction of apoptosis in cardiac allografts.
Circulation. 2000; (19 Suppl 3): III228-32
Apoptosis is thought to occur during immune-mediated acute rejection of cardiac allografts. In vitro studies have shown that zinc inhibits the activity of the proapoptotic enzyme caspase-3. We hypothesized that ZnCl(2) would reduce acute cardiac rejection in vivo via the blockade of caspase-3-dependent apoptosis. (99m)Tc-labeled annexin V was used to measure apoptosis in cardiac allografts through nuclear imaging. Annexin V binds to phosphatidylserines, which are externalized to the outer membrane of apoptotic cells.
