After partial hepatectomy , liver regeneration was significantly delayed.
The possibility of poly (ADP-ribosyl) ation playing a role during liver regeneration induced by partial hepatectomy (PH) in vivo was examined.
The abundant nuclear enzyme poly (ADP-ribose) polymerase catalyses the synthesis of poly (ADP-ribose) from nicotinamide adenine dinucleotide (NAD +).
Poly (adenosine 5 ' - diphosphate ribose) (poly (ADP-ribose)) is spontaneously ADP-ribosylated when it is incubated with nicotinamide adenine dinucleotide , especially in 0.5 M NaCl and at an alkaline pH..
