| Polycystic ovary syndrome (PCOS) is a multifactorial disease, which is resulted from the three common features,
hyperandrogenism (HA), ovulatory dysfunction (OD), and polycystic ovarian morphology (PCOM). The environmental
inducers (like diet, lifestyle, chemicals, drugs, and ageing) and cardiometabolic risk factors (such as
insulin resistance, metabolic syndrome, and obesity) are involved in pathogenesis of PCOS. The growing body of
evidence has been shown that there exist endothelial cell dysfunction (ECD) in women with PCOS independent
of age, weight and metabolic abnormalities. It has been shown that a broad spectrum of cardiovascular risk
markers are involved in ECD- induced cardiovascular disease. It is well described that there are no worldwide
treatments for PCOS and all of pharmacological treatments are off -label without any approval. MNAM is one of
potential therapeutic factor, which produced by nicotinamide N-methyltransferase (NNMT) via consumption of
S-adenosyl methionine (SAM) and nicotinamide. Only one study has shown higher expression of its producer
enzyme, NNMT, in the cumulus cells of women with PCOS. Therefore, we reviewed beneficial effects of MNAM
on modulation of cardiometabolic risk factors, which are associated to PCOS and try to describe possible mode of
action of MNAM in the regulation of these markers. |
