Saponins from the roots of Platycodon grandiflorum ameliorate high fat diet-induced non-alcoholic steatohepatitis
چکیده انگلیسی


- CKS ameliorates HFD-induced hepatic fibrosis.
- CKS inhibits HFD-induced pro-inflammatory cytokines and fibrotic markers.
- The effect relies on the activation of antioxidant enzyme and fatty acid oxidation.

Platycodon grandiflorum has been healthy effects due to its various nutritious compounds and is considered as a functional food. Platycodon grandiflorum root-derived saponins (CKS) have been reported to show a variety of effects including anti-inflammatory and anti-oxidative activity. Although CKS have been studied on various bioactivities, the inhibitory effect of CKS on non-alcoholic steatohepatitis (NASH) is not examined. In this study, the inhibitory effects on HFD-induced NASH by CKS were determined. CKS suppressed HFD-induced hepatic lipid peroxidation level, collagen deposition, pro-fibrogenic and pro-inflammatory cytokines expression. CKS treatment suppressed HFD-induced COX-2 expression via inhibition of NF-κB p65 nuclear translocation and IκBα degradation. CKS treatment restored HFD-reduced Nrf2-mediated antioxidant enzymes expression. Furthermore, CKS treatment reinstated HFD-reduced peroxisomal proliferator-activated receptor alpha (PPARα)-regulated acyl-coA oxidase and carnitine-palmitoyl-coA transferase-1 expression. These findings suggest that CKS reduces HFD-induced NASH by up-regulation of Nrf2-mediated anti-oxidant enzymes and PPARα-regulated fatty acid oxidation.
