Abstract:
The present invention relates to a composition, a kit, and a method of diagnosing metastasis of ovarian cancer or predicting the metastasis probability by detecting methylation levels of CpG sites of prostaglandin-endoperoxide synthase 2 (PTGS2) genes.
Abstract:
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 quickly diagnose the risk of metastasis, and to develop a convenient diagnostic kit with high accuracy. CONSTITUTION: A composition for diagnosing ovarian cancer metastasis or the risk of metastasis contains an agent which measures methylation levels of CpG site of an IFITM1(interferon-induced transmembrane 1) 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 a GABRP gene promoter; and a primer which is specific to a non-methylated sequence of the GABRP gene promoter. A method for measuring methylation levels of CpG site comprises: a step of treating genome DNA 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 amplifies CpG site.
Abstract:
The present invention relates to a composition for diagnosing metastatic characteristics or estimating the metastasis riskness of ovarian cancer by detecting the CpG methylation status of NTN4 (netrin 4) genes, a kit, and a method thereof. The composition for diagnosing metastatic characteristics or estimating the metastasis riskness of ovarian cancer contains an agent for measuring the CpG methylation status of the NTN4 (netrin 4) genes. The agent contains: a compound deforming a non-methylated cytosine base or a methylation sensitive restriction enzyme; a primer specific to a methylated sequence of a CpG domain of the NTN4 genes; and a primer specific to a non-methylated sequence.
