mRNA差异显示技术是一种克隆差异表达基因的方法。由于其简便、快速 ,并不断改进 ,近年来得到了广泛的应用。前列腺表型多样、发生机理复杂。运用该方法已经在前列腺肿瘤中克隆出许多新基因和发现已知基因的新功能 ,表明mRNA差异显示是研究前列腺癌生物学的有力技术 ,有着广阔的应用前景。 mRNA differential display technology is a clone of differentially expressed genes. Due to its simplicity, speed, and continuous improvement, it has been widely used in recent years. Prostate diverse phenotype, complex mechanism of occurrence. Using this method, many new genes have been cloned in prostate tumors and found new genes known function, indicating that mRNA differences display is a powerful technique for the study of prostate cancer biology, which has broad application prospects.
