ABSTRACT
OBJECTIVE:
To explore the effect of arsenic trioxide combined with itraconazole on proliferation and apoptosis of KG1a cells and its potential mechanism.METHODS:
The cell morphology was observed with Wrighe-Giemsa staining; cell survival rate was examined by CCK-8; and colony formation capacity was measured by methylcellulose colony formation test; the flow cytometry was used to analyse the cell apoptosis rate and cell cycle; the protein expressions of BCL-2,caspase-3,BAX,SMO,Gli1 and Gli2 were detected by Western-blot.RESULTS:
The arsenic trioxide and itraconazole alone both could inhibit the KG1a cell proliferation in dose-and time-dependent manner. In comparison between single and combined drug-treatment group, both the cell survival rate and the colony number of the single drug-treatment group were significantly lower(P<0.05), and the apoptosis rate was higher in the combined drug-treatment group. In the combined-treatment group, the protein expression of Caspase-3 and BAX was upregulated, while the protein expression of BCL-2,SMO,Gli1 and Gli2 was downregulated.CONCLUSION:
Arsenic trioxide combined with itraconazole can inhibit the KG1a cell proliferation and induce apoptosis, which may be related with the inhibition of Hh signaling pathway and upregulation of both Caspase-3 and BAX protein expression, and provided experimental data of arsenic trioxide combined with itraconazole for the treatment of refractory AML.
