ABSTRACT
Objective@#To analyze the effects of Clostridium difficile toxin B (TcdB) on the proliferation and apoptosis of colon cancer cell line SW480 and the possible mechanisms related to cell apoptosis.@*Methods@#SW480 cells were treated with different concentrations of TcdB. Cell proliferation was detected by MTT assay. Cell apoptosis and mitochondrial membrane potential were measured with flow cytometry.@*Results@#TcdB significantly inhibited the proliferation of SW480 cells in a time-concentration dependent manner and the inhibition rate reached 46.36% at 48 h. Flow cytometry results showed that TcdB could induce the apoptosis of SW480 cells in a time-concentration dependent manner and a 20.83% apoptosis rate was induced by 800 ng/ml of TcdB at 48 h.@*Conclusions@#TcdB could inhibit the proliferation and induce the apoptosis of colon cancer SW480 cells, and the possible mechanisms might be relate to the initiation of mitochondrial apoptosis pathway.
