Hepatic histopathology was performed, and biochemical parameters for APAP metabolism and necrosis were investigated, including depletion of glutathione\/glutathione-disulfide (GSH+GSSG), \u03b2-nicotinamide adenine dinucleotide (NADH+NAD+), and adenosine triphosphate (ATP); release of aminotransferases and Dnase1; and occurrence of DNA fragmentation. As expected, an APAP overdose in WT mice led to massive hepatocellular necrosis characterized by the release of aminotransferases and depletion of hepatocellular GSH+GSSG, NADH+NAD+, and ATP.
