摘要: 目的: 以livin mRNA 为靶点设计反义硫代脱氧寡核苷酸(PS-ODNs), 探讨其体外抗肿瘤效应及其机制。方法: 设计以livin mRNA 为靶点的反义核酸并作用于MCF-7 乳癌细胞, 用MTT、RT-PCR 和流式细胞仪检测等方法对其进行评价研究。结果: 在设计的一些反义核酸中, YMZ05 能够有效地抑制livin 基因的表达, 增加caspase-3 的活性, 诱导MCF-7细胞凋亡, 明显抑制其生长, 结论: 通过抑制livin 基因的表达能够抑制MCF-7 乳癌细胞生长、诱导其凋亡, livin 可能会成为抗肿瘤的新靶点。

Abstract: AIM: To design antisense phosphorothioate oligodeoxynucleotides (PS-ODNs) which targeted to livin mRNA and investigate the anti-cancer effects and the mechanism in vitro.METHODS: Several antisense PS-ODNs were designed and exposed to MCF-7 breast cancer cells.MTT, RT-PCR, flow cytometry and caspase-3 assay were tested in the experiment.RESULTS: The level of livin mRNA was decreased and the activity of caspase3 was increased by YMZ05 in several PS-ODNs designed.The growth of MCF-7 was inhibited and the cell apoptosis was induced by PS-ODN.CONCLUSION: The inhibition of livin can inhibit the growth of MCF-7 breast cancer cells and induce the apoptosis of it.The livin may become a new potential target of anticancer therapy.

Key words: antisense, phosphorothioate oligodeoxynucleotides (PS-ODNs), livin mRNA, MCF-7 cell, cell apoptosis
