The Effects of Wortmannin on Leukemia Cells Proliferation Cycle and BCL-2 Expression / 中国医师杂志

ABSTRACT

Objective To investigate the effects of wortmannin (WT) on leukemia cells cycle and BCL-2 protein expression. Methods 0 25?mol/L PI-3 kinase inhibitor wortmanin was used to treat K562 cells for 24 hours, and Arac was simultaneously used to induce the cell apoptosis. The specific fluoresent staining and FCM analysis were adopted to measure the cell cycle distribution and BCL-2 expression. Results Compared with the control cells, the proliferation index(PI) of the K562 cells treated by wortmannin was significantly lower, the cell number of G1 phase and the percentage of cell apoptosis increased, and the BCL-2 protein expression significantly decreased. Conclusion Wortmannin could inhibitedtheproliferationofK5 6 2cells ,andwascellcyclespecificagent (CCSA) .
