Abstract:
1. A method for diagnosing Alzheimer's disease, the method comprising the steps of: (a) measuring a methylation level of a CpG site located at −374 from a transcription start site of HMOX1 (Heme oxygenase 1) gene in a biological sample of a human individual, the CpG site corresponding to position 627 of SEQ ID NO. 1, (b) comparing the methylation level to a methylation level of a corresponding gene in control samples without Alzheimer's disease, and (c) determining that the human individual has Alzheimer's disease when the methylation level measured in the sample of the human individual is lower than the methylation level measured in the control samples, wherein step (a) comprises the steps of: treating genomic DNA in the biological sample with bisulfite, amplifying the bisulfite-treated genomic DNA using a set of primers consisting of SEQ ID NOS: 10 and 13, a set of primers consisting of SEQ ID NOS: 11 and 13, or a set of primers consisting of SEQ ID NOS: 14 and 15, and determining the methylation level of the CpG site by a methylation-specific polymerase chain reaction, real time methylation-specific polymerase chain reaction, pyrosequencing, or bisulfite sequencing.
