Abstract

Hepatic ischemia-reperfusion (IR) injury remains the major cause of liver damage post-liver surgery or transplantation. Diminishing oxidative stress and inflammatory responses is a powerful channel to reduce the rate of morbidity and mortality. Gastrodin (GSTD), a bioactive compound extracted from the traditional Chinese herbal agent with a long history of clinical application in nervous system diseases, is suggested to possess anti-oxidative effects on liver diseases, such as nonalcoholic fatty liver disease. However, the therapeutic potential of GSTD in liver IR injury remains unclear. In this paper, we performed surgery to set up the 70% hepatic IR injury models in mice after a three-day pretreatment of GSTD. We found the administration of GSTD reduced liver damage, which correlated with lower histological Suzuki's score, lower serum alanine transaminase (AST) and alanine transaminase (ALT) levels, less oxidative stress, and cell apoptosis in a dose-responsive manner, as compared to the parallel control. Meanwhile, we observed a great induction of heme oxygenase-1 (HO-1) and an activation of the p38 mitogen-activated protein kinases/nuclear factor erythroid 2-related factor 2 (p38MAPK/Nrf2) pathway in response to the GSTD pr...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
