The mRNA level of the TGF-β receptor II and the Smads in CNE2 and NP69 cells. (A) Expression level of the TβRII, Smad 2, Smad 3, Smad 4, Smad 7 in CNE2 cells and NP69 cells by RT-PCR using specific primers. β-actin was used as a control and was further to normalize. (B) Bar diagram of the TβRII, Smad 2, Smad 3, Smad 4, Smad 7 mRNA level from densitometric measurement of three real-time quantitative PCR from three separate treatments. * Statistically significant (P < 0.05, t-test) as compared with NP69 group.** Statistically significant (P < 0.01, t-test) as compared with NP69 group.
