摘要: 目的

探讨冬凌草甲素对子宫内膜癌HEC-1B细胞增殖、迁移和侵袭的影响,阐明其可能机制。

方法

取对数生长期的子宫内膜癌HEC-1B细胞分为对照组(DMSO培养液)、 阳性对照组(2.5 mg·L-1顺铂)、低剂量(10 μmol·L-1)冬凌草甲素组、中剂量(20 μmol·L-1)冬凌草甲素组和高剂量(40 μmol·L-1)冬凌草甲素组。采用MTT法检测细胞增殖抑制率,流式细胞术检测细胞凋亡率,细胞划痕实验检测细胞迁移能力,Transwell小室实验检测HEC-1B细胞侵袭能力,实时荧光定量聚合酶链式反应(RT-qPCR)法检测各组HEC-1B细胞中长链非编码RNA(lncRNA)结肠癌相关转录因子1(CCAT1)表达水平。

结果

与对照组比较,阳性对照组和低、中及高剂量冬凌草甲素组HEC-1B细胞凋亡率明显升高(P<0.05);细胞划痕愈合率和穿膜细胞数均明显降低(P<0.05);HEC-1B细胞中lncRNA CCAT1表达水平明显降低(P<0.05)。与低剂量冬凌草甲素组比较,中和高剂量冬凌草甲素组HEC-1B细胞凋亡率明显升高 (P<0.05),细胞划痕愈合率和穿膜细胞数均明显降低(P<0.05),HEC-1B细胞中lncRNA CCAT1表达水平明显降低(P<0.05)。与中剂量冬凌草甲素组比较,高剂量冬凌草甲素组HEC-1B细胞凋亡率明显升高 (P<0.05),细胞划痕愈合率和穿膜细胞数均明显降低(P<0.05),HEC-1B细胞中lncRNA CCAT1表达水平明显降低(P<0.05)。

结论

冬凌草甲素可以抑制癌细胞增殖、迁移和侵袭,促进子宫内膜癌HEC-1B细胞凋亡,其作用机制可能与下调lncRNA CCAT1表达水平有关。

Abstract: Objective

To investigate the effects of oridonin on the proliferation, migration and invasion of endometrial cancer HEC-1B cells, and to elucidate its possible mechanism.

Methods

The endometrial cancer HEC-1B cells in logarithmic growth phase were divided into control group(DMSO), positive control group(2.5 mg·L-1cisplatin),low dose(10 μmol·L-1)of oridonin group, medium dose (20 μmol·L-1)of oridonin group and high dose (40 μmol·L-1)of oridonin group. MTT assay was used to detect the inhibitory rates of proliferation of cells. Flow cytometry was used to determine the apoptotic rates of HEC-1B cells. Cell scratch test was used to detect the cell migration ability. Transwell chamber assay was used to detect the invasion ability of HEC-1B cells. Real-time fluorescence quantitative PCR(RT-qPCR) was used to detect the expression levels of lncRNA CCAT1 in the cells.

Results

Compared with control group, the apoptotic rates of HEC-1B cells in positive control group, low,medium and high doses of oridonin groups were significantly increased (P<0.05),the scratch healing rates and the number of transmembrane cells were significantly reduced (P<0.05),and the expression levels of lncRNA CCAT1 in the HEC-1B cells were significantly decreased (P<0.05). Compared with low dose of oridonin group, the apoptotic rates of HEC-1B cells in medium and high doses of oridonin groups were significantly increased (P<0.05),the scratch healing rates and the number of transmembrane cells were significantly reduced (P<0.05),and the expression levels of lncRNA CCAT1 in the HEC-1B cells were significantly decreased (P<0.05). Compared with medium dose of oridonin group, the apoptotic rate of HEC-1B cells in high dose of oridonin group was significantly increased (P<0.05),the scratch healing rate and the number of transmembrane cells were significantly reduced (P<0.05),and the expression level of lncRNA CCAT1 in the HEC-1B cells was significantly decreased (P<0.05).

Conclusion

Oridonin can inhibit the proliferation, migration,and invasion and promote the apoptosis of endometrial cancer HEC-1B cells, and its mechanism may be related to down-regulating the expression level of lncRNA CCAT1.
