     To investigate the effect of SB431542 on the accumulation of TGFβ1 and MMP3 in MM cells, RPMI 8226 cells are treated with 10, 100 and 1,000 nmol/mL SB431542 for 48 h. Western blotting is performed. The results demonstrate that SB431542 significantly decreases the accumulation of TGFβ1 and MMP3 at 100 and 1,000 nmol/mL when compared with the control. Smad2, as a signaling molecule, can be initially activated by TGFβ1. Therefore, the effect of SB431542 on the expression of Smad2 and p-Smad2 in RPM
