摘要
【目的】探讨黄芪甲苷对高糖诱导的人绒毛膜滋养层细胞(HTR-8/SVneo)焦亡及侵袭迁移的影响。【方法】将HTR-8/SVneo细胞分为4组:对照组(未处理)、高糖组(高糖刺激)及黄芪甲苷50、100μmol/L组(高糖刺激+黄芪甲苷)。采用细胞计数试剂盒8(CCK-8)法检测细胞活力,分别采用Transwell实验和划痕实验测定细胞侵袭、迁移能力,Hoechst 33342/碘化丙啶(PI)双荧光染色评估细胞焦亡情况,蛋白免疫印迹(Western Blot)法检测细胞NOD样受体热蛋白结构域相关蛋白3(NLRP3)、胱天蛋白酶剪切体(cleaved-Caspase-1)、消皮素D-N端(GSDMD-NT)、白细胞介素18(IL-18)蛋白表达水平。【结果】与对照组比较,高糖组HTR-8/SVneo细胞活力显著降低,细胞迁移率显著降低,侵袭细胞数显著减少,PI阳性细胞比例显著增加,NLRP3、cleaved-Caspase-1、GSDMD-NT、IL-18蛋白表达水平显著升高(P<0.05或P<0.01);与高糖组比较,黄芪甲苷处理组细胞活力显著升高,细胞迁移率显著增加,侵袭细胞数显著增加,PI阳性细胞比例显著下降,NLRP3、cleaved-Caspase-1、GSDMD-NT、IL-18蛋白表达水平显著下降(P<0.05或P<0.01)。【结论】黄芪甲苷可抑制高糖诱导的HTR-8/SVneo细胞焦亡,改善细胞侵袭及迁移能力。
Objective To investigate the effect of astragalosideⅣon high glucose-induced pyroptosis and invasive migration of human chorionic trophoblast cells(HTR-8/SVneo).Methods HTR-8/SVneo cells were divided into 4 groups:control group(untreated),high glucose group(high glucose stimulation)and astragalosideⅣ50 and 100μmol/L group(high glucose stimulation+astragaloside).Cell activity was detected by Cell Counting Kit 8(CCK-8),cell invasion and migration abilities were determined by Transwell assay and scratch assay,respectively,cell pyroptosis was assessed by Hoechst 33342/propidium iodide(PI)dual fluorescence staining.The protein expression levels of NOD-like receptor thermoprotein structural domain(NLRP3),cleaved-Caspase-1,GSDMD-NT,and IL-18 were detected by Western Blot.Results Compared with the control group,HTR-8/SVneo cell viability was significantly reduced in the high glucose group,the rate of cell migration was significantly reduced,the number of invasive cells was significantly reduced,the percentage of PI-positive cells was significantly increased,and the levels of NLRP3,cleaved-Caspase-1,GSDMD-NT and IL-18 protein expression levels were significantly increased(P<0.05 or P<0.01);compared with the high glucose group,cell viability was significantly higher in the astragalosideⅣtreated group,the rate of cell migration was significantly increased,the number of invasive cells was significantly increased,the percentage of PI-positive cells was significantly decreased,and the protein expressions of number of NLRP3,cleaved-Caspase-1,GSDMD-NT,IL-18 were significantly decreased(P<0.05 or P<0.01).Conclusion AstragalosideⅣcan inhibit high glucoseinduced HTR-8/SVneo cell pyrolysis and improve cell invasion and migration ability.
