JinSanE decoction, a chinese herbal medicine, inhibits expression of TGF-beta1/Smads in experimental hepatic fibrosis in rats.

The study is to investigate the effects of a Chinese herbal medicine, JinSanE decoction, on the TGF-beta1/Smads signal transduction pathway in a carbon tetrachloride (CCl(4))-induced hepatic fibrosis model in rats. Rats were randomly divided into 4 study groups: namely, a normal control group, a hepatic fibrosis model group, and 2 treatment groups with different doses of JinSanE (6 and 12 g/kg). Ten rats in each group were sacrificed at 4 and 8 weeks after exposure to CCl(4) respectively.

Effects of Chinese traditional compound, JinSanE, on expression of TGF-beta1 and TGF-beta1 type II receptor mRNA, Smad3 and Smad7 on experimental hepatic fibrosis in vivo.

Aim: The transforming growth factor-beta (TGF-beta)/Smad signaling pathway system plays a prominent role in the control of cell growth and extracellular matrix formation in the progression of liver fibrogenesis. Smad proteins can either positively or negatively regulate TGF-beta responses. In this study, the therapeutic effects of Chinese traditional compound decoction, JinSanE, and the changes of TGF-beta/Smad signaling pathway system in carbon tetrachloride (CCl(4))-induced rat experimental liver fibrosis were examined.

Objective: To investigate the therapeutic effects of perindopril, an angiotensin-converting enzyme inhibitor, and valsartan, an angiotensin II receptor blocker on TGFbeta1 and TGFbeta receptor II mRNA, Smad3 and Smad7 on rat liver fibrosis.

Methods: 60 Wistar rats were randomly divided into four groups (each group, n=15). Group 1 rats were not treated and served as healthy controls.
