摘要:

目的: 探讨双氢青蒿素(DHA)对神经母细胞瘤细胞生长的抑制作用,阐明DHA抗神经母细胞瘤的作用机制。方法: 实验分为空白对照组和DHA组(DHA终浓度分别为0.05、0.50、5.00和50.00 μmol·L-1)。采用MTT法检测DHA作用后SH-SY5Y细胞的增殖率,流式细胞术分析DHA作用后SH-SY5Y细胞周期的变化,ELISA和Western blotting法分析DHA作用后SH-SY5Y细胞中cyclin D1和caspase-3蛋白表达水平的变化。结果: 不同浓度DHA作用SH-SY5Y细胞24、48和72h时均可抑制细胞的生长,与空白对照组比较,0.50、5.00和50.00 μmol·L-1 DHA组SH-SY5Y细胞增殖率明显下降(P<0.05或P<0.01);细胞生长的密度随药物浓度的升高而降低。与空白对照组比较,50.00 μmol·L-1 DHA组SubG1期细胞的百分比增加(P<0.05);G0/G1期细胞百分比先升高再降低,S期与G2/M期细胞的百分比减少。与空白对照组比较,50.00 μmol·L-1 DHA组SH-SY5Y细胞中cyclinD1蛋白表达水平降低(P<0.05);与空白对照组比较,50.00 μmol·L-1DHA组caspase-3蛋白表达水平升高(P<0.05)。结论: DHA可能通过阻滞肿瘤细胞周期、促进肿瘤细胞凋亡而抑制神经母细胞瘤细胞的生长。

Abstract:

Objective: To explore the inhibitory effect of dihydroartemisinin (DHA) on the growth of neuroblastoma cells, and to clarify the anti-tumor mechanism of DHA.Methods: The experiment was divided into blank control group and DHA groups (the final concentrations of DHA were 0.05, 0.50, 5.00 and 50.00 μmol·L-1).The proliferation rates of neuroblastoma SH-SY5Y cells after treated with DHA were examined by MTT assay; the changes of cell cycle of SH-SY5Y cells after treated with DHA were examined by flow cytometry;the expression levels of cyclin D1 and caspase-3 proteins were detected by ELISA and Western blotting methods.Results: The proliferation of SH-SY5Y cells 24, 48, and 72 h after treated with different concentrations of DHA were inhibited.Compared with blank control group, the proliferation rates of SH-SY5Y cells in 0.50, 5.00 and 50.00 μmol·L-1DHA groups were significantly decreased(P<0.05 or P<0.01).The density of cells was decreased with the increasing of DHA concentration.Compared with blank control group, the percentage of SH-SY5Y cells at SubG1 phase in 50.00 μmol·L-1 DHA group was increased(P<0.05), and the percentage of cells at G0/G1 phase was increased first then was decreased; otherwise, the percentages of cells at S and G2/M phase were decreased.Compared with blank control group, the expression level of cyclin D1 protein in 50.00 μmol·L-1 DHA group was decreased(P<0.05), but the expression level of caspase-3 protein in 50.00 μmol·L-1 DHA group was increased(P<0.05).Conclusion: DHA could inhibit the proliferation through arresting the cell cycle and inducing the apoptosis of neuroblastoma cells.
