【摘要】Objective To investigate the mechanism of AS2 O3 inducing the apoptosis of myelodysplastic syndrome(MDS) cell line SKM-1 .Methods SKM-1 cells were incubated with AS2 O3 ,and then the cellular morphology was observed ,flow cytometry was used to determine the apoptosis ,RT-PCR was used to detect the expressions of Bcl-2 ,Bax and caspase-3 mRNA .Results 0 .25、0 .50 μmol/L AS2 O3 could not markedly induce the apoptosis of SKM-1 cells (P>0 .05) .But 2 .00、8 .00、32 .00 μmol/L of AS2 O3 could obviously promote the apoptosis of SKM-1 cells .With the increase of the acting time and concentration of AS2 O3 ,the apoptosis rate increased ,too(P<0 .01) ,the expressions of anti-apoptotic gene Bcl-2 mRNA decreased (P<0 .01) ,the expressions of promoting apoptosis gene Bax and caspase-3 mRNA increased (P<0 .01 ,P<0 .05) .Conclusion 2 .00、8 .00、32 .00 μmol/L of AS2O3 may promote the apoptosis of SKM-1 cells through down-regulating the expression of Bcl-2 gene and up-regulating the ex-pressions of Bax and caspase-3 genes .%目的：探讨三氧化二砷（ AS2O3）诱导骨髓增生异常综合征（MDS）SKM-1细胞的凋亡机制。方法将AS2O3与SKM-1细胞共
