Abstract:
Objective To investigate the effect of FTY720 and gemcitabine on the proliferation and apoptosis of H520 and A549 cells in non-small cell lung cancer(NSCLC) cell line.Methods The interventional influence on the in vitro cultured NSCLC A549 and H520 cells was performed by selecting 0,2,4,6,8,10 μmol/L concentrations of FTY720,then the absorbance value was detected at 24,48,72 h after culture and the proliferation inhibiting effects of FTY720 on A549 and H520 were observed under the condition of different concentration of FTY720;adding single 7 μmol/L of FTY720,single 0.2 μmol/L gemcitabine and 37 μmol / L FTY720 combined with 0.2 mol/L gemcitabine into A549 and H520 cells lines,then the differences of inhibition and apoptosis after 48 h in the cells of each group were observed.Results The inhibitory effect of different concentrations of FTY270 on NSCLC A549 and H520 cell lines was statistically significant difference (P＜0.05).The proliferation inhibiting effect of FTY720 on NSCLC H520 and A549 cell lines had the correlation with the concentration and time.The apoptosis rate of FTY720 combined with gemcitabine on A549 and H520 cells was significantly higher than that of single use in these two drugs (P＜0.05).Conclusion FTY720 combined with gemcitabine can significantly inhibit the proliferation of A549 and H520 in human NSCLC,and can effectively promote the apoptosis of cancer cells,and has the higher clinical value.
