In our previous study, it was found that dihydro-stilbene gigantol relieved hepatic inflammation in mice with CCl\n                    <jats:sub>4<\/jats:sub>\n                    -induced acute liver injury. This study aimed to investigate the involvement of arachidonate metabolic cascade in this process. Our results showed CCl\n                    <jats:sub>4<\/jats:sub>\n                    activated AA metabolism with the evidence of cPLA2 phosphorylation, which was dependent on the MAPK\/JNK activation. Pretreatment with JNK inhibitor SU3327 or gigantol abolished the cPLA2 activation, along with the attenuation of liver damage. Besides, gigantol markedly decreased immune cells activation. Metabolomic analysis revealed that gigantol universally reversed the upregulation of major AA metabolites in injured mouse livers induced by CCl\n                    <jats:sub>4<\/jats:sub>\n                    , especially 12-hydroxyeicosatetraenoic acid (12-HETE). Gigantol also decreased the mRNA and protein expression of platelet-, and leukocyte-type 12-lipoxxygenase (LOX) in the liver. Furthermore, pan-LOX inhibitor nordihydroguaiaretic acid (NDGA) and specific 12-LOX inhibitors baicalein and ML351 attenuated the liver injury to the same extent as gigantol. Overall, our study elucidated a comprehensive profile of AA metabolites during hepatic inflammation caused by CCl\n                    <jats:sub>4<\/jats:sub>\n                    , highlighting the role of 12-LOX-12-HETE pathway in this process.
