摘要: 目的:研究黑种草子总皂苷提取物(TSNG)对人宫颈癌SiHa细胞的增殖、迁移、凋亡和自噬等生物学行为的影响。方法:将SiHa细胞分为空白对照组和不同浓度(0.8、0.9、1.0、1.1、1.2、1.4、1.6、1.8 mg/mL)的TSNG作用组,以及10 μmol/L羟氯喹(HCQ)干预组;四甲基噻唑蓝(MTT)法检测各组细胞的生长抑制率;划痕实验检测细胞的相对迁移率;流式细胞术Annexin V-FITC/PI染色法检测细胞凋亡率;Hoechst染色观察细胞核凋亡现象;单丹磺酰戊二胺(MDC)染色观察细胞内自噬体数量;Western blot实验检测LC3-Ⅱ和p62蛋白表达。结果:与空白对照组相比,TSNG对细胞的生长有抑制作用且呈剂量效应关系(P<0.05或0.01);0.9、1.0、1.1 mg/mL TSNG处理组细胞相对迁移率分别为(20.40±2.49)%、(15.14±0.39)%、(5.05±1.04)%,均低于空白对照组的(36.63±2.52)%(P<0.01);1.0、1.2、1.4 mg/mL TSNG处理组细胞的凋亡率分别为(39.10±0.22)%,(68.37±0.58)%和(80.93±0.12)%,均高于空白对照组的(10.73±0.82)%(P<0.05或0.01);与空白对照组比较,TSNG处理组细胞核表现出凋亡现象细胞数量增多,且细胞内自噬体数量增加,LC3-Ⅱ和p62蛋白表达上升(P<0.05或0.01);相较于TSNG作用组,HCQ预处理组LC3-Ⅱ蛋白表达无显著变化(P>0.05)。结论:TSNG对SiHa细胞体外增殖、迁移表现出明显的抑制作用,并在诱导细胞凋亡的同时阻断细胞自噬流。

Abstract: OBJECTIVE: To investigate the effects of total saponins from the seeds of Nigella glandulifera Freyn (TSNG) on proliferation,migration,apoptosis and autophagy of SiHa cells. METHODS: SiHa cells were divided into untreated control group,TSNG (0.8,0.9,1.0,1.1,1.2,1.4,1.6,1.8 mg/mL) treatment group and HCQ (10 μmol/L) intervention group. Growth inhibition was detected by using the MTT assay. Anti-migration effects were detected by the cell scratch assay. Apoptosis rates were determined using the flow cytometry assay with Annexin V-FITC/PI staining. Nuclear apoptosis was observed after Hoechst staining. The formation of autophagosomes was detected after MDC staining. Protein expressions of LC3-Ⅱ and p62 were detected by Western blotting. RESULTS: Compared with the control group,TSNG had an inhibitory effect on cell growth which shows a dose-dependent effect relationship (P<0.05 or 0.01). The relative migration rates from the 0.9,1.0,1.1mg/mL TSNG treatment groups were (20.40±2.49)%,(15.14±0.39)% and (5.05±1.04)%,which were lower than those of the control group (36.63±2.52)% (P<0.01). The apoptosis rates from the 1.0,1.2,1.4 mg/mL TSNG treatment groups were (39.10±0.22)%,(68.37±0.58)% and (80.93±0.12)%,respectively,which were higher than those of the control group (10.73±0.82)% (P<0.05 or 0.01). Compared with the control group,the cell nuclei from thef TSNG treated group showed more apoptotic changes, increased autophagosomes,and increased the LC3-Ⅱ and p62 protein expressions (P<0.05 or 0.01). Compared with the TSNG treatment group,LC3-Ⅱ protein expressions had no significant changes after HCQ pretreatment. CONCLUSION: TSNG exposure caused inhibition of proliferation and of migration,induced apoptosis and blocked autophagy in SiHa cells.
