Polycystic Ovary Syndrome (PCOS) is a common endocrine and metabolic disorder that
affects women in their reproductive age. Recent studies have shown that genes have an important
role in the etiology of PCOS. However, the precise way in which these genes are transcriptionally
and post-transcriptionally regulated is poorly understood.
The aim of the present review is to provide updated information on miRNAs and DNA methylation
as epigenetic marks of PCOS.
The data presented here allow concluding that both microRNAs and DNA methylation can be considered
as possible useful biomarkers when choosing the treatment for a specific PCOS phenotype
and thus represent two important tools for the diagnosis and treatment of PCOS patients.
