Figure 3. Inhibit expression of laminin after transfection with pSup-Smad7 siRNA. There is significance among expression of laminin protein in the HTM of Smad7siRNA group, TGF-β2 group, control group, and TGF-β2 plus vehicle group (p<0.01). Downregulation of laminin was detected in HTM transfected with pSup-Smad7 siRNA.
