1 APAP caused rapid GSH depletion, extensive protein adduct formation in liver homogenates and in mitochondria, JNK phosphorylation and mitochondrial translocation of phospho-JNK within 2 h, oxidant stress, and extensive centrilobular necrosis at 6 h. A438079 significantly attenuated GSH depletion, which resulted in a 50% reduction of total liver and mitochondrial protein adducts and substantial reduction of JNK activation, mitochondrial P-JNK translocation, oxidant stress, and liver injury.
