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.
Abstract:
PURPOSE: A composition for diagnosing Alzheimer's disease is provided to diagnose Alzheimer's disease by identifying the methylation of a heme oxygenase 1 (HMOX1) gene promoter using a biomarker. CONSTITUTION: A composition for diagnosing Alzheimer's disease contains a formulation which measures the methylation level of a HMOX1 gene promoter. A method for providing information for diagnosing Alzheimer's disease comprises the steps of: measuring the methylation level of the HMOX1 gene promoter from a biological sample of a patient who is suspected to have Alzheimer's disease; and comparing the measured methylation level with the methylation level of a control group sample.
