The DNA-dependent protein kinase (DNA-PK) is a heterotrimeric enzyme that binds to double-stranded DNA and is required for the rejoining of double-stranded DNA breaks in mammalian cells. It has been proposed that DNA-PK functions in this DNA repair pathway by

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

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.

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
