Abstract
The purpose of the current study was to investigate the effect of Magnesium Isoglycyrrhizinate (GM) on cyclophosphamide (CP)-induced hepatic injury in vivo and in vitro. The results demonstrated that GM exerted a protective effect on CP-induced acute liver injury, as evidenced by the alleviations of hepatic pathological damage and serum transaminase activities. Meantime, GM attenuated serum and HepG2 cell supernatant levels of TNF-α, IL-6, IL-1β, SOD and MDA. Western blot results presented that GM down-regulated the expressions of the microtubule associated protein 1A/1B-light chain 3 (LC3), Lysosome associated membrane protein-1 (LAMP-1), p-phosphatidylinositol 3-kinase (PI3K), p-protein Kinase B(Akt), p-mechanistic target of rapamycin(mTOR), p-ribosomal protein S6 kinase 70 kDa (p70S6K), p-4E binding protein 1(4EBP1), p- inhibitor of NF-κB(IκB)α and p-nuclear factor kappa B(NF-κB)p65 in CP-stimulated hepatic tissue and HepG2 cells. Taken together, our results suggested that GM showed beneficial effect on CP-induced liver injury through NF-κB-mediated inflammation and PI3K/Akt/mTOR/p70S6K/4EBP1 axis-mediated autophagy in vivo and in vitro.
