| Abstract: |
Carbon tetrachloride (CCl4)-induced lipid peroxidation associated with hepatic oxidative stress and cell death is an important mechanism of acute liver injury (ALI). Ginsenoside Rd is considered an active ingredient of ginseng. Evidence suggests that ginsenoside Rd may improve ischaemic stroke, nerve damage, cancer and other diseases involving apoptosis, inflammation, oxidative stress, mitochondrial injury and autophagy. However, the effects of ginsenoside Rd on CCl4-induced ALI and its underlying mechanisms are still unclear. In this study, 0.25% CCl4 was injected intraperitoneally in mice to establish a CCl4-induced ALI model. In the Rd treatment group, Rd (10, 20 mg/kg) doses were injected intraperitoneally 1 h before and 23 h after CCl4 administration. Ferroptosis inducer imidazole ketone erastin (IKE) was injected intraperitoneally 4 h before CCl4 administration to explore the mechanism. The blood and liver were collected 24 h after CCl4 administration to investigate the effect and mechanism of ginsenoside Rd on CCl4-induced ALI. Our results showed that ginsenoside Rd inhibited CCl4-induced ALI in mice. Ginsenoside Rd also downregulated CCl4-induced serum and liver iron, 4-hydroxynonenal, and 8-hydroxy-2 deoxyguanosine levels. Furthermore, it upregulated glutathione and glutathione peroxidase 4 levels. In addition, ginsenoside Rd downregulated the expression of cGAS and STING. Subsequently, the ferroptosis inducer imidazole ketone erastin significantly reversed the hepatoprotective effect and influence of ginsenoside Rd with regard to the indicators mentioned above. Our study confirmed that ginsenoside Rd ameliorated CCl4-induced ALI in mice, which was related to the reduction of ferroptosis. Simultaneously, the ginsenoside Rd-mediated inhibition of the cGAS/STING pathway contributed to its antiferroptosis effect. In conclusion, our results suggested that ginsenoside Rd inhibited ferroptosis via the cGAS/STING pathway, thereby protecting mice from CCl4-induced ALI. These results suggested ginsenoside Rd may be used as a potential intervention treatment against CCl4-induced ALI. [ABSTRACT FROM AUTHOR] |
