Abstract

Statement of the Problem: Polycystic ovary syndrome (PCOS) is a common disorder in women that characterized by an increase in follicle number, hyperandrogenism, and ovulatory disfunction. In PCOS patients, anti-mullerian hormone (AMH) has been shown to be two- or three-fold higher as compared to health women. The cause of the increased AMH production in PCOS is unknown; however, increased concentrations may be a consequence of other factors altered in PCOS, for example DNA methylation, a principle mechanism of epigenetic. The objective of this study was to evaluate the methylation level in the promoter region of AMH gene.

Methodology and Theoretical Orientation: To evaluate methylation level in PCOS, we used whole blood from 13 patients compared to health women. Methylation level of AMH promoter in both groups was analysed using methylation-specific PCR (MSP).

Findings: The intensity of AMH methylation bands was found lower among the PCOS, 33.64%, respectively, compared to control (Fig. 1). The methylation level of AMH gene promoter in PCOS patients (12.97±5.13) was significantly different compared to control (46.61±1.77) obtained from healthy women (p<0.001).

Conclusion: Promoter region of AMH gene in PCOS are hypomethylated compared to health women. This hypomethylation in AMH gene might be contribute in increasing the level of AMH in serum from women with PCOS.
