    • PURPOSE: A composition for diagnosing metastatic ovarian cancer is provided to measure methylation levels of a certain gene promoter site of genome DNA isolated from a patient's sample by MSP(Methylation-Specific PCR), to diagnose the risk of metastasis, and to develop a convenient diagnostic kit with high accuracy. CONSTITUTION: A composition for diagnosing ovarian cancer metastasis or predicting the risk of metastasis contains an agent which measures methylation levels of CpG site of MUC13(mucin 13) gene promoter. The agent contains a compound which modifies non-methylated cytosine or a methylation-sensitive restriction enzyme, a primer which is specific to a methylated sequence of GABRP gene promoter, and a primer which is specific to a non-methylated sequence of GABRP gene promoter. A method for measuring methylation levels of CpG site of the gene promoter comprises: a step of treating genome DNA in a sample with the compound which modifies non-methylated cytosine or the methylation-sensitive restriction enzyme; and a step of amplifying the treated DNA by PCR using a primer which is able to amplify CpG site of MUC13 gene promoter.
    • 目的:提供一种用于诊断转移性卵巢癌的组合物,以测量通过MSP(甲基化特异性PCR)从患者样品中分离的基因组DNA的某个基因启动子位点的甲基化水平,以诊断转移的风险,并开发方便 诊断套件具有高精度。 构成:用于诊断卵巢癌转移或预测转移风险的组合物含有测量MUC13(mucin 13)基因启动子CpG位点甲基化水平的试剂。 该试剂含有修饰非甲基化胞嘧啶或甲基化敏感性限制性酶的化合物,对GABRP基因启动子的甲基化序列特异的引物和对GABRP基因启动子的非甲基化序列特异的引物。 用于测量基因启动子的CpG位点的甲基化水平的方法包括:用修饰非甲基化胞嘧啶或甲基化敏感性限制酶的化合物处理样品中的基因组DNA的步骤; 以及使用能够扩增MUC13基因启动子的CpG位点的引物通过PCR扩增处理的DNA的步骤。
