Protective effects of the total saponins from Dioscorea nipponica Makino against carbon tetrachloride-induced liver injury in mice through suppression of apoptosis and inflammation
چکیده انگلیسی


• Total saponins from D. nipponica Makino (TSDN) with purity > 80% was produced.
• TSDN showed protective activity against CCl4-induced liver injury in mice.
• TSDN showed anti-apoptosis, anti-oxidant and anti-inflammatory activities.

The present study was to investigate the effects and possible mechanisms of the total saponins from Dioscorea nipponica Makino (TSDN) against CCl4-induced hepato-toxicity in mice. The mice were orally administrated with TSDN for seven days and then given CCl4 (0.3%, 10 ml/kg i.p.). The results showed that TSDN significantly attenuated the activities of ALT and AST, consistent with hematoxylin–eosin staining. The ALP levels and relative liver weight were significantly decreased by TSDN compared with model group. Moreover, TSDN dramatically decreased MDA, iNOS and NO levels, while the levels of GSH, GSH-Px and SOD were increased. Further investigations showed that TSDN inhibited CCl4-induced metabolic activation and CYP2E1 expression, down-regulated the levels of MAPKs phosphorylation, NF-κB, HMGB1, COX-2 as well as effectively suppressed the expressions of Caspase-3, Caspase-9, PARP and Bak. Quantitative real-time PCR assay demonstrated that TSDN obviously decreased the gene expressions of TNF-a, IL-1β, IL-6, IL-10, Fas, FasL, Bax as well as modulated Bcl-2 mRNA level. This is the first time to report the protective actions of the TSDN against CCl4-induced liver damage in mice through suppression of inflammation and apoptosis. This natural product should be developed as a new drug for treatment of liver injury in future.
