Activation of the poly(ADP-ribose) polymerase after oxidative damage is implicated in different responses of the cells, for example, cell recovery after sublethal damage or cell death after lethal damage. However, the extent and mechanism of involvement of the enzyme in

The cardioprotective properties of inhibition of poly (ADP-ribose) synthetase (PARS) were investigated in the isolated perfused heart of the rat. Hearts were perfused in the Langendorff mode and subjected to 23 min total global ischaemia and reperfused for 60 min.

The activation of poly (ADP-ribose) synthetase (PARS) subsequent to DNA damage caused by reactive oxygen or nitrogen species has been implicated in several pathophysiological conditions, including ischemia-reperfusion injury and shock. The aim of this study was to investigate whether PARS

Endothelial cells (EC) are subject to oxidative-induced cell death. Activation of poly(ADP-ribose) polymerase (PARP) occurs early in oxidant-induced EC injury and putatively mediates cell death by depleting its substrate, NAD(+). In this study, the role of PARP in H(2)O(2)-induced EC
G M Wray et al.
Shock (Augusta, Ga.), 10(1), 13-19 (1998-08-04)
The nuclear enzyme poly(ADP-ribose) synthetase (PARS) is activated by DNA strand breakage, caused, for example by nitric oxide (NO), peroxynitrite, or oxygen-derived free radicals. Activation of PARS can cause intracellular energy depletion and cell death in vitro and may play
