INF-γ对肝纤维化大鼠TGF-β1/Smad3蛋白表达的影响
Effect of INF-γ on hepatic fibrosis in rats of TGF-β1/Smad3 protein expression
摘要
Abstract
Objective To observe the INF- γ on hepatic fibrosis and changes of TGF- β 1> Smad3 protein expression, and explore the mechanism of INF- γ in treating hepatic fibrosis. Methods Male SD rats were divided into three groups, model group and experimental group were injected with thioacetamide (thioacetamide, TAA) 100 mg/kg, 2 days by intraperitoneal injection to induce rat hepatic fibrosis, The control grounp was injected with equal amount of physiological saline, while the experimental group treated with INF- γ intramuscularly .Model group and control group injected with equal physiological saline. All rats were sacrificed at 8 weeks ,stained with Masson to observate hepatic fibrosis, detected TGF- β 1, Smad3 protein levels with immunohistochemistry in hepatic tissue. Results The degree of experimental group hepatic fibrosis, the expression of TGF- β 1, Smad3 was higher than that in the normal group (P<0. 05), significantly lower than that in the model group (P<0.05). Conclusion IFN- γ may inhibit TGF- β 1/Smad3 protein expression, and thus play a role in hepatic fibrosis.关键词
