摘要: 目的: 观察白英水提物诱导人宫颈癌HeLa 细胞凋亡的作用, 并初步探讨其分子机制。方法: 常规方法制备白英水提物, 体外培养人宫颈癌HeLa 细胞。实验组设白英水提物12.5、25.0、50.0 mg/mL 3种浓度, 以顺铂(25.0 mg/L) 为阳性对照组。采用细胞毒试验(MTT 法) 检测HeLa 细胞抑制率, 荧光显微镜观察HeLa 细胞形态变化, 琼脂糖凝胶电泳检测DNA 梯形泳带, 半定量RT-PCR 法检测凋亡相关基因survivin mRNA 和caspase-3 mRNA 表达的变化。结果: 白英水提物对HeLa 细胞增殖有抑制作用, 且呈明显的时效和量效关系, 并诱导其发生凋亡, 表现为细胞核固缩、染色质凝集、边聚等。琼脂糖凝胶电泳显示DNA 梯形泳带, 半定量RT-PCR 法检测显示survivin mRNA 表达下调、caspase-3 mRNA 表达上调。结论: 白英水提物对HeLa 细胞有较强的增殖抑制和诱导凋亡作用, 其诱导HeLa 细胞凋亡的分子机制可能与上调caspase-3 基因表达、下调survivin 基因表达有关。

Abstract: AIM: To investigate the apoptosis-inducing and proliferation inhibition effect of solanum lyratum thunb (SLT) extract and its molecular mechanism on human cervical cancer HeLa cells. METHODS: Dried whole herbs of SLT were extracted by boiling distilled water.Human cervical cancer HeLa cells were randomly divided into the control group, SLT-treated groups (12.5, 25.0, 50.0 mg/mL) and DDP (25.0 mg/L) group. Morphological changes of apoptosis were observed by fluorescence microscope.DNA ladders were examined by DNA agarose gel electrophoresis and the expression of survivin mRNA and caspase-3 mRNA were detected by semiquantitative RT-PCR. RESULTS: SLT extract displayed a strong proliferation inhibitory effect in a dose-and-timedependent manner in HeLa cells.Nuclear shrinkage, chromatin condensation and margination were observed under a fluorescence microscope in HeLa cells treated with SLT extract and DDP.Survivin mRNA levels were down-regulated while caspase-3 were up-regulated. CONCLUSION: SLT extract displays a strong proliferation inhibitory and apoptosis-inducing effect in a doseand-time-dependent manner in HeLa cells.The molecular mechanism of apoptosis of HeLa cells induced by SLT extract has possibly related to up-regulating expression of caspase-3 gene and down-regulating survivin gene.
