摘要:

目的:观察20(s)-原人参二醇(PPD)对体外培养人宫颈癌Siha细胞凋亡的作用,阐明其抗肿瘤作用机制。方法:体外培养人宫颈癌Siha细胞,将其分为阴性对照组(乙醇)、阳性对照组(40 μg/L顺铂)及PPD 10、20和40 μmol/L组。分别用乙醇、顺铂和PPD处理细胞48 h后,利用光学显微镜观察细胞形态学改变,采用Annexin V-EGFP/PI双染色法、TUNUL染色法检测细胞凋亡情况,分别采用RT-PCR、Western blotting方法检测bax基因的转录及蛋白表达情况。结果:不同剂量的PPD处理后,Siha细胞变圆回缩并出现碎片,Annexin V-EGFP/PI染色呈现不同程度的绿染和红染,TUNUL染色可见绿色荧光,bax基因的转录与蛋白表达升高。结论:PPD可诱导人宫颈癌Siha细胞出现凋亡,其作用与bax基因表达上调有关。

Abstract:

Abstract:Objective To study the effect of 20(s)-proto-panaxdiol(PPD)on apoptosis of Siha cells in vitro,and clarify the mechanism of its anticancer action. Methods Siha cells cultivated in vitro were treated with alcohol,40 μg/L Platinol(Pt),10 μmol/L PPD,20 μmol/L PPD,40 μmol/L PPD for 48 h,respectively.The morphological changes of Siha cells were observed under optical microscope.Apoptosis was detected by Annexin V-EGFP /PI staining and TUNUL staining.The transcription and the protein expression of bax were analyzed by RT-PCR and Western blotting.Results After treated with PPD,the cells were round,recovery,and broken.Green and red fluorescence was shown in Annexin V-EGFP/PI staining,green fluorescence was evident in TUNUL staining.The transcription and the protein expression of bax were up-regulated.Conclusion PPD may induce the apoptosis of Siha cells,and its mechanism may be related to the up-regulation of bax expression.
