Figure 3From: The effect of transforming growth factor-β1 on nasopharyngeal carcinoma cells: insensitive to cell growth but functional to TGF-β/Smad pathwayThe expression of the TGF-β receptor II and the Smads in CNE2 and NP69 cells. Expression level of the TβRII, Smad 2, Smad 3, Smad 4, Smad 7 in CNE2 cells and NP69 cells by western blot. Actin was used as a protein loading control and was further to normalize. Relative density was account between NP69 and CNE2 group.Back to article page
