Identification of diagnostic DNA methylation markers in the blood of Japanese Alzheimer's disease patients using methylation capture sequencing.

ABSTRACT:

Background

Methylation capture sequencing (MC-seq), which relies on next-generation sequencing technology, offers advantages over the widely used array-based approach that Illumina Inc. developed regarding both resolution and comprehensiveness for detecting DNA methylation changes across genomes. In the present study, MC-seq was employed for the first time to identify DNA methylation markers for Alzheimer's disease (AD).

Results

We compared DNA methylation in the blood of 12 AD patients with brain amyloidosis and 12 cognitively normal elderly Japanese individuals without brain amyloidosis. Candidate methylation differences were validated in the two cohorts using bisulfite amplicon sequencing. Significant differentially methylated regions were identified in the ANKH, MARS, AN
