摘要: 目的 探讨青蒿琥酯(Art)对肾母细胞瘤细胞系(SK-NEP-1)增殖、凋亡和自噬的影响。方法 以不同浓度的Art(0、10、20、40和80 μmol/L)干预SK-NEP-1细胞,MTT法检测细胞增殖抑制率,筛选最佳干预浓度;将SK-NEP-1细胞分为对照组、Art组、3-MA组(Art+自噬抑制剂,3-甲基腺嘌呤)、Rapa组(Art+自噬激活剂雷帕霉素),EdU、流式细胞测量术分别检测细胞增殖、凋亡;丹磺酰尸胺(MDC)染色法检测细胞自噬;DCFH-DA荧光探针检测细胞活性氧(ROS)的水平;Western blot检测细胞中增殖细胞核抗原(PCNA)、细胞抗凋亡因子B淋巴细胞瘤-2(Bcl-2)、Bcl-2相关X蛋白(Bax)、微管连接蛋白1轻链3Ⅱ/3Ⅰ(LC3Ⅱ/LC3Ⅰ)、选择性自噬接头蛋白1(p62)和Beclin-1蛋白表达。结果 与0 μmol/L Art相比,10、20、40和80 μmol/L Art处理后SK-NEP-1细胞增殖抑制率逐渐升高(P<0.05),IC50值为46.881 μmol/L,故选取40 μmol/L Art进行后续实验。与对照组相比,Art组SK-NEP-1细胞凋亡率、相对自噬荧光强度、ROS水平、Bax、LC3Ⅱ/LC3Ⅰ、Beclin-1、PINK1、Parkin蛋白表达水平显著升高,EdU阳性细胞率、PCNA、Bcl-2、p62蛋白表达水平显著降低(P<0.05);自噬抑制剂3-MA可减弱Art对肾母细胞瘤细胞凋亡和自噬的促进作用,对增殖的抑制作用(P<0.05)。结论 Art抑制肾母细胞瘤细胞系的增殖,促进细胞自噬和凋亡。

Abstract: Objective To investigate the effects of artesunate (Art) on the proliferation, apoptosis, and autophagy of nephroblastoma cell line (SK-NEP-1). Methods SK-NEP-1 cells were intervened with different concentrations of Art (0, 10, 20, 40 and 80 μmol/L), and MTT method was applied to calculate the cell proliferation inhibition rate to screen the optimal intervention concentration; SK-NEP-1 cells were separated into control group, Art group, 3-MA group (Art+autophagy inhibitor, 3-methyladenine), and Rapa group (Art+autophagy activator rapamycin). EdU and flow cytometry were applied to detect cell proliferation and apoptosis, respectively; MDC staining was applied to detect autophagy in cells; the level of reactive oxygen species (ROS) in cells was detected by DCFH-DA fluorescent probe; the expression of proliferating cell nuclear antigen (PCNA), anti apoptotic factor B cell lymphomatoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), microtubule junction protein 1 light chain 3Ⅱ/3Ⅰ (LC3Ⅱ/LC3Ⅰ), selective autophagy junction protein 1 (p62), and benzyl chloride 1 (Beclin-1) proteins in cells were detected by Western blot. Results Compared with 0 μmol/L Art, the proliferation inhibition rate of SK-NEP-1 cells was gradually increased after 10, 20, 40 and 80 μmol/L Art treatment (P<0.05), and the IC50 value was 46.881 μmol/L, so 40 μmol/L Art was selected for follow-up experiments. Compared with the control group, the apoptosis rate, relative autophagy fluorescence intensity, ROS level, Bax, LC3 Ⅱ/LC3 Ⅰ, Beclin-1, PINK1, and Parkin protein expression levels of SK-NEP-1 cells in the Art group were obviously increased, the EdU positive cell rate, PCNA, Bcl-2, and P62 protein expression levels were obviously reduced (P<0.05); The autophagy inhibitor 3-MA inhibited the promoting effect of Art on apoptosis and autophagy of nephroblastoma cells and inhibit proliferation (P<0.05). Conclusions Art inhibits the proliferation of nephroblastoma cell line SK-NEP-1, and promotes autophagy and apoptosis.
