Hirudin Ameliorates Renal Interstitial Fibrosis via Regulating TGF-β1/Smad and NF-κB Signaling in UUO Rat Model

Figure 4

Effect of hirudin on the expression of TGF-β1/Smad signaling in UUO rats. (a–c) Western blot of TGF-β1, p-Smad2, Smad-2, p-Smad3, and Smad3; GAPDH was used as the loading control. (d–f) Protein levels of TGF-β1, p-Smad2/Smad-2, and p-Smad3/Smad-3 in each group. Data are expressed as mean ± SD. For comparison among the UUO group and the control group, indicates . For comparison among the hirudin-treated groups and UUO group, indicates and indicates .
