摘要
Various therapeutic approaches are conducted for regression of liver fibrosis and prevent possible further carcinogenic transformation. This study was aimed to assess the prospective therapeutic potential of bromelain against thioacetamide (TAA)-induced liver fibrosis using in-vitro and in vivo approaches. In vitro study, HSC-T6 cell line was used to evaluate the effect of bromelain on HSC-T6 cell viability and apoptosis. In vivo, Rats were treated by TAA for 6 weeks for induction of hepatic fibrosis followed by post treatment by different doses of bromelain and silymarin for further 4 weeks to assess the regression of hepatic fibrosis. The in-vitro findings indicated that bromelain hindered the proliferation of HSCs in concentration dependent manner compared with the untreated cells. The in vivo study revealed that treatment of TAA fibrotic rats with different doses of bromelain and silymarin induced a significant restoration in liver function biomarkers, attenuation of oxidative stress, upregulation of total antioxidant capacity and thereby decline of fibrotic biomarkers and improving histopathological and immunohistochemical changes. In conclusion, This study indicates that bromelain can regress TAA induced hepatic fibrosis in rats via inhibiting HSCs activation, α-SMA expression and the ECM deposition in hepatic tissue in addition to its antioxidants pathway, these findings prove the promising therapeutic potential of bromelain as a novel therapeutic approach for chronic hepatic fibrotic diseases.
