Aloe-emodin is an anthraquinone with potential pharmacological properties, including numerous antitumor properties. The purpose of the study was to determine whether aloe-emodin induces mitotic death in cervical cancer cells.
Analysis of morphological changes as surrogate mitotic death indicators in HeLa cells was carried out using optical, fluorescence and electron microscopy. Viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide reduction assay. Cell-cycle analysis was performed using flow cytometry.
Aloe-emodin increased the number of multinucleate cells, giant and micronuclear cells. There was a concentration-dependent decrease in the mitotic index with a predominance of cells in the metaphase of the mitotic process and inhibition of division in the G/M phase of the cell cycle. The presence of cells with abnormal mitosis and cells with injury to the division spindle was also demonstrated.
Aloe-emodin induces mitotic catastrophe in cervical cancer cells.
芦荟大黄素是一种具有潜在药理特性的蒽醌类化合物,具有多种抗肿瘤特性。本研究的目的是确定芦荟大黄素是否能诱导宫颈癌细胞发生有丝分裂死亡。
利用光学显微镜、荧光显微镜和电子显微镜分析HeLa细胞中作为有丝分裂死亡替代指标的形态变化。通过3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴盐还原试验测定细胞活力。使用流式细胞术进行细胞周期分析。
芦荟大黄素增加了多核细胞、巨核细胞和微核细胞的数量。有丝分裂指数呈浓度依赖性下降,有丝分裂过程中期细胞占优势,且细胞周期的G/M期分裂受到抑制。还证实了存在有异常有丝分裂的细胞和纺锤体受损的细胞。
芦荟大黄素可诱导宫颈癌细胞发生有丝分裂灾难。
