摘要 目的探讨在HEK293T细胞中miRNA-17对其靶基因整合素受体β8(ITG-β8)调控作用,从而为治疗心血管疾病寻找新的靶点。方法通过实时定量PCR法检测转染重组表达载体pCDNA3.1+miRNA-17后成熟miR-NA-17的表达水平。应用生物信息学预测软件对miRNA-17的靶基因进行预测,将靶基因ITG-β8的3'UTR融合到pMIR荧光素酶基因下游,通过双荧光素酶报告基因检测miRNA-17对靶基因ITG-β8的3'UTR的调控作用。设计合成反义寡核苷酸序列(ASO-miRNA-17),通过ITG-β8转染于HEK293T细胞。结果双荧光素酶报告基因分析表明,miRNA-17能够作用于ITG-β8基因的3'UTR。反义寡核苷酸技术进一步证实,ASO-miRNA-17抑制性调控miR-NA-17的表达。结论 miRNA-17可以负性调节靶基因ITG-β8的表达。
