ABSTRACT
Objective To explore the effect of atorvastatin on the proliferation and apoptosis of K562 cells andto investigate its mechanisms.Methods The cells were treated by different concentrations of atorvastatin.The CCK-8 assay was employed to detect the cell proliferation.The cell apoptosis was detected by AnnexinV-FITC/PI dual staining;the flow cytometry was used to detect the cellular cycle;the activities of caspase-3,-8,-9 were detected by the colorimetric method;qRT-PCR was employed to measure the mRNA expression levels of Bcl-2 and PDCD5 in K562 cells.Results Atorvastatin could inhibit the proliferation of K562 cells in a time-and dose-dependent manner(P<0.05);and induced the apoptosis of K562 cells,the percentage of G0/G1 phase cells was increased after atorvastatin treating k562 cells(P<0.01),while the percentage of S phase cells was decreased(P<0.01),moreover which showing the concentration dependence(P<0.01);atorvastatin activated the caspase-3,-8,-9 (P<0.01);down-regulated Bcl-2 mRNA expression and up-regulated PDCD5 mRNA expressionin a concentration dependence(P<0.01).Conclusion Atorvastatin can inhibit the proliferation and induce apoptosis in K562 cells.
