Figure 8. Downregulation of caveolin-1 increased the TGF-β1-induced collagens production.

Figure 8

HAFs in the siRNA-cav group were transfected with the caveolin-1 siRNA using Hiperfect transfection reagent following protocols provided by the manufacturer, and then HAFs were treated with 100 ng TGF-β1 for 48 h. HAFs in TGF-β1 group were only treated with 100 ng TGF-β1 for 48 h for western blot or 24 h for qRT-PCR. Note that downregulation of caveolin-1 with the caveolin-1 siRNA increased the TGF-β1-induced the mRNA level (B) and protein level (A) of collagen I and III production in HAFs. HAFs, human atrial fibroblasts. siRNA-Cav, the caveolin-1 siRNA. *P<0.05 vs. control group. #P<0.05 vs. TGF-β1 group. n = 3 per group; measurement in triplicate for each single experiment.
