Effect of Exogenous Fetuin-A on TGF-β/Smad Signaling in Hepatic Stellate Cells

Figure 3

The protein abundance of Smad2, Smad3, and Smad7. (a) Representative bands showing the changes of Smad2, Smad3, Smad7, and GAPDH. Lane A: blank control group; Lane B: TGF-β1 experimental group; Lane C: TGF-β1 + fetuin-A experimental group; Lane D: TGF-β1+ asialofetuin-A experimental group. (b) Densitometric analysis of Smad2, Smad3, Smad7, and GAPDH. Relative protein expression was analyzed by western blot. Experimental treatments were analyzed in quadruplicate. The positive bands were quantitatively analyzed by Gel Pro 4.0 Analysis software after their integrated optical density (IOD) was measured. The housekeeping gene (GADPH) was used as an internal control. Data were represented as mean ± SD. Statistics were obtained with a one-way analysis of variance (ANOVA) test. Asterisk represents .
