Abstract:

In the present study, we found that oyster peptide (OP) could ameliorate hepatic fibrosis through the NF-κB/iNOS signaling pathway. A total of 50 male Sprague-Dawley rats were randomly divided into five groups by the random digital table method: control group, model group, low-dose (0.5 g/kg) OP group, medium-dose (1.0 g/kg) OP group, and high-dose (2.0 g/kg) OP group, with 10 rats in each group. The rat model of hepatic fibrosis was established by subcutaneous injection of 50% carbon tetrachloride (CCl4). In OP therapy groups, the expressions of collagen I, collagen III, and TGF-β1 in the liver with CCl4-induced hepatic fibrosis were significantly lower than those in the model group (P < 0.05). OP could down-regulate the expressions of NF-κB and iNOS in the liver tissue of rats with hepatic fibrosis. Collectively, OP ameliorated hepatic fibrosis, possibly through the NF-κB/iNOS signaling pathway.
