Figure 6. TGFβ receptor antibody and TGFβ receptor inhibitor rescued the effect of TAZ siRNA on cell growth. A: NHC cells were treated with TGFβ receptor type I antibody together with mock siRNA or TAZ siRNA. Relative cell density was analyzed from three replicates. a: a significant reduction of cell density after TAZ siRNA treatment. “b”: the cell growth inhibition was rescued by TGFβ receptor I antibody treatment. B: NHC cells were treated with TGFβ receptor inhibitor (SB431542) together with mock siRNA or TAZ siRNA. Relative cell density was analyzed from three replicates. “a’”: a significant reduction of cell density after TAZ siRNA treatment. “b’”: cell growth inhibition was rescued by SB431542. Data were represented as mean±se (p<0.05).
