The goal of these investigations was to measure levels of DNA in the plasma of mice following administration of hepatotoxic agents to induce apoptotic or necrotic cell death and determine any differences in the release of this marker depending upon death pathway. For this purpose, the effects of varying doses of anti-Fas, acetaminophen (APAP) or carbon tetrachloride (CCl4) were assessed in normal mice. Plasma DNA was measured fluorometrically by the dye PicoGreen while lactate dehydrogenase (LDH) and caspase 3, other molecules released with cell injury or death, were measured by enzymatic assays. Histology was used to assess the occurrence of apoptosis or necrosis. Results of these experiments indicate that increased blood DNA levels occurred with all three agents and were highest with anti-Fas and CCl4; caspase 3 levels were much higher with anti-Fas than the other agents. Histological examination confirmed the predominance of apoptotic death with anti-Fas and necrotic death with APAP and CCl4. These results indicate that increased blood DNA is common in hepatotoxic injury and is a feature of both apoptotic and necrotic death.
