Figure 5. TβRII siRNA interferes with fibronectin and alpha-smooth muscle actin (α-SMA) production. The level of fibronectin secreted and α-SMA expression to the culture media was analyzed by western blotting. Samples were from cultures untreated (lane 3), treated with scrambled siRNA (lane 2), or 80 nM (lane 1) hT3. The fibronectin (Fn) and α-SMA bands are labeled.
