摘要
目的:观察Micro RNA100(mi R-100)在对阿霉素耐药的乳腺癌细胞的表达情况。方法:培养并传代人乳腺癌阿霉素耐药细胞(MCF7/ADM)以及人乳腺癌细胞(MCF7),提取细胞中的micro RNA,使用Real-time RT-PCR对mi R-100的表达水平进行相对定量分析,并采用非配对t检验对两种细胞中mi R-100的表达情况进行统计分析。结果:在正常人乳腺癌细胞中,mi R-100表达量非常少,但在MCF7/ADM细胞中mi R-100表达明显上调,与MCF7细胞比较,差异具有统计学意义。结论:mi R-100在对阿霉素耐药的人乳腺癌细胞中呈现高表达,有机会作为一个乳腺癌耐药潜在的治疗、诊断靶点。
objective:Observe Micro RNA100(mi R-100) on adriamycin resistance expression of breast cancer cells.Methods:develop and extend the adriamycin resistance of breast cancer cells(MCF7 / ADM) and human breast cancer cell(MCF7),extract the mirnas in the cell,use the Real-time rt-pcr expression levels of mi R-100 relative quantitative analysis,and using the paired t test for two kinds of cells in the expression of mi R-100 cases were analyzed.Results:in normal human breast cancer cells,the expression of mi R-100 quantity is less,but mi R-100 in MCF7 / ADM cells express raised obviously,compared with MCF7 cells,the difference is statistically significant.Conclusion:mi R-100 in adriamycin resistance show high expression in human breast cancer cells,have the opportunity to as a potential treatment of breast cancer drug resistance,diagnostic targets.
