Influence of Bufalin on the Growth and Proliferation of Human Glioma Cell Line U251 / 中国药师

ABSTRACT

Objective:To explore the effects of Bufalin on the growth and proliferation of human glioma cells U251. Methods:Methyl thiazolyl tetrazolium(MTT)assay was used to detect the effect of Bufalin on the proliferation of human glioma cells U251. An in-verted microscope was used to observe the changes of cell number,morphology and activity. AnnexinV/ PI was used to measure the in-duction of cell apoptosis caused by Bufalin. Results:Bufalin at different concentrations(0. 001 - 10. 0μmol·L - 1 )inhibited the pro-liferation of U251 cells in a dose and time-dependent manner. Compared with that of the control group,the apoptosis rate of Bufalin group was increased significantly(P < 0. 01). Conclusion:Bufalin can inhibit the growth and proliferation of U251 cells in a dose and time-dependent manner,and induce the apoptosis of U251 cells.
