摘 要:BACKGROUND Liver fibrosis is a refractory disease whose persistence can eventually induce cirrhosis or even liver *** liver fibrosis is reversible by *** a member of the transforming growth factor-beta(TGF-β)superfamily,bone morphogenetic protein 7(BMP7)has anti-liver fibrosis ***,little is known about BMP7 expression changes and its potential regulatory mechanism as well as the relationship between BMP7 and TGF-βduring liver *** addition,the mechanism underlying the anti-liver fibrosis function of BMP7 needs to be further *** To investigate changes in the dynamic expression of BMP7 during liver fibrosis,interactions between BMP7 and TGF-β1,and possible mechanisms underlying the anti-liver fibrosis function of *** Changes in BMP7 expression during liver fibrosis and the interaction between BMP7 and TGF-β1 in mice were *** BMP7 was used to treat mouse primary hepatic stellate cells(HSCs)to observe its effect on activation,migration,and proliferation of HSCs and explore the possible mechanism underlying the anti-liver fibrosis function of *** with liver fibrosis received exogenous BMP7 intervention to observe improvement of liver fibrosis by using Masson’s trichrome staining and detecting the expression of the HSC activation indicator alpha-smooth muscle actin(α-SMA)and the collagen formation associated protein type I collagen(Col I).Changes in the dynamic expression of BMP7 during liver fibrosis in the human body were further *** In the process of liver fibrosis induced by carbon tetrachloride(CCl4)in mice,BMP7 protein expression first increased,followed by a decrease;there was a similar trend in the human *** process was accompanied by a sustained increase in TGF-β1 protein *** vitro experiment results showed that TGF-β1 inhibited BMP7 expression in a time-and dose-dependent *** contrast,high doses of exogenous BMP7 inhibited TGF-β1-induced activation
