Potential effect of recombinant thrombomodulin on ischemia-reperfusion liver injury in rats. Hepatol Res 2018; 48:391-396. [PMID: 29168258 DOI: 10.1111/hepr.13005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 10/18/2017] [Accepted: 11/18/2017] [Indexed: 02/08/2023]
Abstract
AIM Liver ischemia-reperfusion (I/R) injury is a severe complication of liver surgery. However, the responsible molecular mechanism remains unclear. High-mobility group box 1 (HMGB1) is released from the nuclei of cells and behaves as a damage-associated molecular pattern. The aim of this study is to reveal the roles of HMGB1 and the effects of recombinant thrombomodulin (rTM) in I/R liver injury. METHODS Rats underwent partial hepatic ischemia followed by reperfusion, and changes in HMGB1 were assessed. Recombinant thrombomodulin was used as an inhibitor of HMGB1. RESULTS In rats with I/R injury, the HMGB1 level significantly decreased in the liver tissue and significantly increased in the serum after surgery (P < 0.001 for both). No difference in the HMGB1 level in the hepatocytes was observed between the rTM(-) group and rTM(+) group after surgery. Conversely, the serum HMGB1 level was significantly lower in the rTM(+) group than the rTM(-) group after surgery (P < 0.001). The levels of tumor necrosis factor-α and interleukin-6 in the liver tissue 24 h after surgery were significantly lower in the rTM(+) group than the rTM(-) group (P < 0.001). The plasma alanine aminotransferase level at 24 h after surgery of the rTM(+) group was significantly decreased after surgery compared with that of the rTM(-) group (P < 0.001). The necrotic area of the liver tissue 24 h after surgery was significantly smaller in the rTM(+) group than the rTM(-) group (P < 0.001). CONCLUSIONS Recombinant thrombomodulin can serve as a treatment for I/R liver injury by inhibiting HMGB1.
