| Outline of Final Research Achievements |
This study was conducted to evaluate the roles of Npc1 gene in the development of acetaminophen (APAP)-induced liver injury in mice. We observed that Npc1 null mice were protected from hepatotoxicity induced by APAP overdose compared with wild-type mice. Although significant difference was mot observed in CYP2E1 expression and toxic metabolite production in liver, the key mediators in APAP hepatotoxicity, such as JNK phosphorylation, nitrotyrosine formation and DNA fragmentation were significantly attenuated in Npc1 null mice.
These results suggest that Npc1, at least in part, play a important role in the development of APAP-induced liver injury.
