title: Increased synthesis of poly(ADP-ribose) in isolated liver nuclei from autoimmune NZB/NZW mice.
abstract: The synthesis and degradation of poly(ADP-ribose) were investigated in isolated liver nuclei from autoimmune NZB/W mice and four strains of normal mice. Compared to normal mice the maximum levels of incorporation of [3H]NAD into poly(ADP-ribose) were increased about 2-fold in the autoimmune mice. The kinetics of incorporation suggested that this change was due to an increase in the activity of the polymerase rather than a decrease in the level of degradative enzymes. Thus there may be a connection between autoimmunity and poly(ADP-ribose) metabolism.
