Neuronal accumulation of poly(ADP-ribose) after brain ischaemia.
Animal and in vitro studies suggest that overactivation of poly(ADP-ribose) polymerase (PARP) in response to oxidative DNA damage makes a substantial contribution to cell death after brain ischaemia. We have recently shown that global brain ischaemia due to cardiac arrest in man induces a rapid increase in the amount of neuronal and glial PARP that can be detected by immunohistochemistry. In the present study we sought evidence of a corresponding increase in the amount of poly(ADP-ribose) wit...Expand abstract
