目的 探讨苦参碱对体外培养的人横纹肌肉瘤RD细胞中X连锁凋亡抑制蛋白(XIAP)表达的影响.方法 体外培养人横纹肌肉瘤RD细胞并分为对照组及0.5 g/L、1.0 g/L、1.5 g/L苦参碱干预组.采用四甲基偶氮唑蓝比色法及流式细胞术分别检测RD细胞在不同质量浓度苦参碱作用下的细胞增殖抑制率及凋亡率的变化,反转录PCR法检测RD细胞中XIAP mRNA的表达.结果 不同质量浓度苦参碱干预组及对照组中RD细胞的增殖抑制率[0.5 g/L苦参碱干预组:(15.84±2.58)%、1.0 g/L苦参碱干预组:(23.13±4.19)%、1.5 g/L苦参碱干预组:(30.32±3.02)%、对照组:(8.92±1.23)%]、凋亡率[0.5 g/L苦参碱干预组:(12.33±1.15)%、1.0 g/L苦参碱干预组:(16.67±0.99)%、1.5 g/L苦参碱干预组:(25.33±1.91)%、对照组:(9.47±0.96)%]及XIAP mRNA表达(0.5 g/L苦参碱干预组:0.633 ±0.046、1.0 g/L苦参碱干预组:0.441 ±0.055、1.5 g/L苦参碱干预组:0.326±0.065、对照组:0.794±0.029)均有差异,且差异有统计学意义(F=14.15、83.37、50.57,P均<0.01).随着苦参碱质量浓度的增加,RD细胞的增殖抑制率及凋亡率明显增加,而XIAP mRNA的表达明显降低,且呈剂量依赖性.结论 苦参碱对人横纹肌肉瘤RD细胞具有抑制增殖及诱导凋亡的作用,且该作用可能与下调凋亡抑制基因XIAP的表达有关.

Objective To investigate the effect of Matrine on the expression of X-linked inhibitor of apoptosis protein (XIAP) in human rhabdomyosarcoma RD cells in vitro.Methods Cultured human rbabdomyosarcoma RD cells were divided into Matrine intervention groups (0.5 g/L,1.0 g/L and 1.5 g/L) and a control group.The proliferation-inhibition rates in RD cells treated with different concentrations of matrine were detected by methylthiazolyl blue colorimetric assay.Flow cytometry analysis was performed for the apoptosis rates of RD cells.Reverse transcription-polymerase chain reaction analysis was used to measure the XIAP mRNA expression.Results There was a significant difference in the proliferation-inhibition rates [0.5 g/L Matrine group:(15.84 ± 2.58)%,1.0 g/L Matrine group:(23.13 ±4.19)%,1.5 g/L Matrine group:(30.32 ±3.02)%,and the control group:(8.92 ± 1.23)%];apoptotic rates [0.5 g/L Matrine group:(12.33 ± 1.15)%,1.0 g/L Matrine group:(16.67 ± 0.99)%,1.5 g/L Matrine group:(25.33 ± 1.91)%,and the control group:(9.47 ± 0.96)%];XIAP mRNA expression(0.5 g/L Matrine group:0.633 ± 0.046,1.0 g/L Matrine group:0.441 ± 0.055,1.5 g/L Matrine group:0.326 ± 0.065,control group:0.794 ±0.029)in RD cells among 0.5 g/L,1.0 g/L,1.5 g/L Matrine groups and the control group (F =14.15,83.37,50.57,all P < 0.05).The proliferation-inhibition and apoptotic rates in RD cells were gradually increased with the increasing Matrine concentration.The expression of XIAP mRNA was significantly decreased in different Matrine groups compared with the control group,exhibiting a dose-dependent manner.Conclusions Matrine can inhibit the proliferation of RD cells and induce the apoptosis in a dose-dependent manner,which may be related to the down-regulated XIAP mRNA.
