At present, the etiology and exact pathogenesis of PCOS are still unclear. Anti-M\u00fcllerian hormone is a local regulator secreted by ovarian granulosa cells, and participates in regulating the occurrence and development of PCOS. Insulin resistance is another important pathophysiological feature of PCOS. Although the expression of anti-m\u00fcllerian hormone receptor (AMHR) and insulin receptor (INSR) in PCOS have been previously reported, the DNA methylation of the genes have not been well characterized. OBJECTIVE: To study AMHR II\/INSR and its role in gene methylation in Ovarian and endometrial pathology of PCOS subjects. METHODS: We recruited seventy-five women with PCOS as cases and twenty healthy women as controls, using immunohistochemical method, study localization, distribution and expression of MHRII\/INSR in ovary and endometrium and then discover the correlation of AMHRII\/INSR gene methylation. RESULTS: Different clinical features in PCOS group AMHRII gene methylation level and insulin resistance relations have significant differences (r= 0.532, P= 0.000); INSR gene methylation level and insulin resistance relations have significant differences (r= 0.281, P= 0.03). CONCLUSIONS: The analysis of DNA methylation suggested that methylation of AMHRII and INSR genes was associated with basic clinical characteristics and insulin resistance of PCOS. These results provide evidence for AMHRII and INSR genes, and their methylation levels are intimately associated with the pathogenesis of PCOS.<\/jats:p>","DOI":"10.3233\/thc-218002","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T13:12:04Z","timestamp":1614690724000},"page":"11-25","source":"Crossref","is-referenced-by-count":31,"title":["DNA
