Aim To investigate the effect of PI3K/AKT/NF-κB signaling pathway in the treatment of physicion-8-O-β-D-monoglu-coside(PMG) on acute liver injury induced by carbon tetracloride(CCl 4) in mice . Methods Mice were randomly assigned into control group, model group, PMG low-dose, medium-dose and high-dose groups and Bifendate groups. After the continuous intervention with PMG for three days, CCl 4oil solution was intraperitoneally injected to establish acute liver injury mouse models, and samples were collected sixteen hours later. HE staining was used to observe the pathological changes of liver tissue. Hoechst 33342 staining was used to detect the number of apoptotic hepatocytes. Western blot was employed to detect the expression levels of caspase-3, PI3K, p-PI3K, AKT, p-Akt, IκB, p-IκB total protein and the nuclear protein NF-κB p65 in mouse liver tissue. The proportion of Th17 cells in mouse liver tissue was detected by FACS. Results After three days of PMG treatment, the pathological injury of liver tissue was relieved, the apoptosis of liver cells and the protein levels of caspase-3(P<0.01) were induced compared with model group.PMG could significantly decrease the nuclear expression of NF-κB p65 in the liver of mice with acute liver injury(P<0.05 or P<0.01). The phosphorylation levels of PI3K, AKT and IκB significantly decreased by PMG(P<0.05 or P <0.01). Otherwise, the proportion of Th17 cells in liver tissue was significantly reduced after PMG treatment(P<0.01). Conclusion PMG can alleviate CCl4 - induced acute liver injury through PI3K/AKT/NF-κB signaling pathway.
