title: Demethylation of LHR in dehydroepiandrosterone-induced mouse model of polycystic ovary syndrome.
abstract: The cause of polycystic ovary syndrome (PCOS), a complex endocrine disorder, is unknown, but its familial aggregation implies underlying genetic influences. Hyperandrogenemia is regarded as a major endocrine character of the PCOS. In this study, we employed bisulfite sequencing and bisulfite restriction analysis to investigate the DNA methylation status of LHR, AR, FSHR and H19 in dehydroepiandrosterone (DHEA)-induced mouse PCOS model. The result showed that methylation of LHR was lost in ovary from induced PCOS mouse. However, AR, FSHR and H19 had similar methylation pattern in DHEA-treated group and control groups. These data provide evidence for close linkage between DNA demethylation of LHR and PCOS.
