Ageing and PARP.

Abstract

Poly(ADP-ribosyl)ation, which is the posttranslational modification of proteins with poly(ADP-ribose), is catalysed by poly(ADP-ribose) polymerases. DNA-strand break induced catalytic activation of two PARP isoforms, namely PARP-1 and -2, are in involved in DNA base-excision repair and other repair pathways. A body of correlative data suggests a link… (More)
