ABSTRACT
c-Jun N-terminal kinase (JNK) is activated during hepatic reperfusion, and JNK inhibitors are known to protect other major organs from ischemia-reperfusion (I/R) injury. We attempted to determine the effect of SP600125, a JNK inhibitor, on hepatic I/R injury using a partial ischemia model in mice. Compared to a vehicle-treated group, the SP600125-treated group showed a greater increase in serum ALT levels 24 h after reperfusion with more severe parenchymal destruction and leukocyte infiltration. Similarly, tissue myeloperoxidase and malondialdehyde levels were higher in the SP600125-treated group, and chemokine expression was also higher in the SP600125-treated group. These data, which are contradictory to previous results, indicate that JNK inhibition by SP600125 may be harmful in hepatic I/R injury. Therefore, care must be taken when investigating the therapeutic use of JNK inhibitors in hepatic I/R injury, especially in the context of the effects of JNK inhibition on inflammatory infiltration.
