Abstract: Abstract: DNA methylation is a common epigenetic modification， which plays an important role in the regulation of gene expression and is closely related to the process of tumorigenesis. Investigating into the methylation patterns in tumor related genes shares tremendous significance in developing technologies for tumor diagnosis and tumor treatment and in understanding the mechanisms underlying tumorigenesis. This review gives an intensive look into the existing DNA methylation detection methods and a brief comment about their relative merits and applications to provide reference for researchers when selecting a proper detection method.
