Effect of 18α-GA on the expression of TGF-β1/Smad signaling pathway related proteins in human and rat HSCs. The protein expression of Smad3, type I and III collagen was significantly decreased, while that of Smad7 dramatically increased at 24 h (P<0.05) and 48 h (P<0.01) after 18α-GA treatment in both cell lines. * P <0.05, ** P <0.01 vs control group.
