Outline of Final Research Achievements

Our previous studies have suggested a link between genomic DNA methylation modification and gene expression characteristic of endometriosis. The objective of this study was to narrow down the diagnostic molecule marker candidate genes using 1,811 DNA methylation modifications located on 93 genes identified by genome-wide DNA methylation analysis of endometriotic cells. The major results suggest that "methylation modification of enhancer characteristic of endometriotic cells results in gene expression characteristic of endometriotic cells". Gene expression under the control of methylation modification of the enhancer in endometriosis may become a diagnostic molecular marker candidate for endometriosis.
