Abstract
Polycystic ovary syndrome (PCOS) is an endocrine metabolic syndrome characterized by ovulation disorders, hyperandrogenemia, and polycystic ovaries, which seriously affect the psychological and physical health of childbearing women. N6-methyladenosine (m6A), as the most common mRNA epigenetic modification in eukaryotes, is vital for developing the female reproductive system and reproductive diseases. In recent years, an increasing number of studies have revealed the mechanisms by which m6A modifications and their related proteins are promoting the development of PCOS, including writers, erasers and readers. In this work, we reviewed the research progress of m6A in the pathophysiological development of PCOS from the starting point of PCOS clinical features, included the recent studies or those with significant findings related to m6A and PCOS, summarized the current commonly used therapeutic methods in PCOS and the possible targeted therapies against the m6A mechanism, and looked forward to future research directions of m6A in PCOS. With the gradual revelation of the m6A mechanism, m6A and its related proteins are expected to become a great field for PCOS treatment.
