ABSTRACT
AIM:
To study if the effect of arsenic sulfide combined with IFN-α can be increased on K562 cells.METHODS:
Telomerase activity was determined by PCRELISA. Flow cytometry was used to analyze the cell apoptosis. The final concentration of IFN-α and arsenic sulfide was 10 000 U/mL and 0.6 mg/L.RESULTS:
The rates of apoptosis was 37.8% and 37% in K562 cells treated with IFN-α or arsenic sulfide alone for 8 days; The rates of apoptosis and inhibition of telomerase activity was 59.9% and 81.2% in K562 cells treated with IFN-α and arsenic sulfide simultaneously for 8 days, or 60.37% and 78.8% in K562 cells was treated with arsenic sulfide for 5 days after affected by IFN-α for 3 days. 71.3% telomerase activity was inhibited in K562 cells by arsenic sulfide alone for 8 days.CONCLUSION:
Combination of arsenic sulfide and IFN-α can increase the apoptosis and inhibit the telomerase activity of K562 cells obviously comparing with the two drugs used alone. IFN-α maybe promote arsenic sulfide inducing apoptosis of K562 cells.
