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.
