【Abstract】 To investigate the inhibition mechanism of calmodulin inhibi to r TFP in the proliferation of BGC-823 cells, the effect of TFP on the prolifera tion of BGC-823 and the level of p16INK4a and cyclinD are assayed respect ively by MTT, FCM and western blot. These results show that TFP inhibits the pro liferation of BGC-823 cells. The level of p16INK4a increases great ly. On the contrary, the level of cyclin D1 decreases obviously. This may be on e of the melecular mechanisms which is involved in the regulation of proliferati on in BGC-823 cells by TFP.更多还原
