Abstract: Objective:To study the influence and mechanism of bufalin on apoptosis and calcium metabolism in human colorectal cancer cell HCT 8. Methods:We used the method of CCK-8 to detect the proliferation of HCT 8 treated with bufalin of different concentrations at 24 hours or the same one at different time. And then , the apoptosis of the cell with different concentrations was detected by Annexin V / PI double staining apoptosis kit. Finally, we investigated the effect of different concentrations of bufalin on intracellular Ca2 + by using Ca2+ fluorescence probe Fluo-3 AM to mark its intracellular Ca2+. Results:The inhibition of human colorectal cancer cell HCT 8 with bufalin showed dose and time dependent manner obviously by the method of CCK-8. The result of apoptosis with flow cytometry illustrated that bufalin can induce apoptosis in the cell HCT 8, and represented a dose-dependent manner. According to the results of the intracellular Ca2+ labeled by calcium fluorescent probe calcium, there was a higher concentration of intracellular calcium when the cell treated at a higher concentration of bufalin. Conclusion:Bufalin can induce apoptosis in the cell of HCT 8, and it may be related to the metabolism of intracellular Ca2+.
