Conclusions
GZFL may prevent the progression of liver fibrosis by regulating the Nrf2/ heme oxygenase-1 and NF-κB signaling pathways, thereby highlighting its role in the management of liver fibrosis.
Methods
Male ICR mice by intraperitoneally administered with 20% CCl (mixed 1∶4 in soybean oil) to induce liver fibrosis. Mice that underwent CCl were orally with GZFL. Using hematoxylin and eosin and Masson staining to examine the pathological changes in liver tissue. Serum biochemical parameters, antioxidant enzyme activity and proinflammatory cytokines was assessed. Nuclear factor-kappaB (NF-κB) pathway and nuclear factor-erythroid 2-related factor 2 (Nrf2) family members were evaluated by Western blotting.
Objective
To evaluate the protective effects and the underlying mechanism of Guizhifuling pill (, GZFL) on carbon tetrachloride (CCl)-induced hepatic fibrosis in mice.
Results
Our findings indicated that GZFL could effectively suppress the progression of liver fibrosis in mice, which was determined based on the improvement in liver function and reduction of collagen deposition. GZFL treatment also decreased the level of cytokines and increased the activity of antioxidant enzymes in liver tissue. Moreover, GZFL exerted anti-inflammatory and antioxidant effects through regulating the Nrf2-mediated antioxidant system and inhibiting the NF-κB pathway. Conclusions: GZFL may prevent the progression of liver fibrosis by regulating the Nrf2/ heme oxygenase-1 and NF-κB signaling pathways, thereby highlighting its role in the management of liver fibrosis.
