摘要: 目的: 研究冬凌草甲素诱导人前列腺癌PC-3细胞凋亡及与PTEN基因表达的关系。方法: MTT比色法测定冬凌草甲素诱导PC-3细胞的增长抑制;流式细胞术分析DNA倍体测定细胞凋亡;RT-PCR半定量分析冬凌草甲素诱导人前列腺癌PC-3细胞后PTEN mRNA的表达情况。结果: MTT比色法测得冬凌草甲素对PC-3细胞具有明显的增殖抑制作用,并随冬凌草甲素浓度的升高及作用时间的延长而增强;流式细胞术分析PC-3细胞经冬凌草甲素诱导后,细胞凋亡比率随作用时间延长而增加。RT-PCR测得PTEN基因mRNA的表达随细胞凋亡的增加而逐渐增高。结论: 冬凌草甲素能够明显抑制PC-3细胞的增殖,并诱导前列腺癌细胞凋亡,其作用途径可能与上调PTEN mRNA表达有关。

Abstract: AIM: To investigate apoptosis of human prostate cancer cell line PC-3 induced by oridonin and the expression relationship with PTEN gene. METHODS: The growth inhibition of PC-3 cell induced by oridonin was analyzed by MTT assay.The apoptosis of cell was detected by analyzing DNA ploid with flowcytomery.The mRNA expression of PTEN gene were detected by reverse transcription polymerase chain reaction (RT-PCR) assay. RESULTS: The proliferation effect of PC-3 cell was significantly inhibited induced by oridonin with dose-and time-dependent manners.The percentage of apoptosis in PC-3 cells was increased with a time-dependent induced by oridonin.With the increasing of apoptosis cell,the mRNA expression of PTEN gene was gradually enhanced. CONCLUSION: Oridonin obviously inhibits the proliferation of PC-3 cell and induces the apoptosis of prostate cancer,and its pathways of action maybe relate with up-regulated the expression of PTEN mRNA.
