Knockdown of Bmi-1 impairs growth and invasiveness of human gastric carcinoma cells.
The effect of B cell-specific MLV integration site-1 (Bmi-1) RNA interference (RNAi)-mediated inhibition of Bmi-1 expression on the proliferation, apoptosis, and invasiveness of human gastric carcinoma AGS cells was investigated. RT-PCR and Western blot analyses demonstrated that Bmi-1 expression and the Bmi-1 protein level were significantly decreased in Bmi-1 shRNA transfected AGS cells compared to untransfected and nonspecific shRNA transfected AGS cells. Bmi-1 RNAi-mediated inhibition of Bmi-1 expression significantly affected cell growth and invasiveness, and resulted in increased AGS cell apoptosis. This was not observed in untransfected and nonspecific shRNA transfected AGS cells. Inhibition of Bmi-1 expression in human gastric carcinoma cells affects cell proliferation and invasiveness.
