Abstract:
The aim of the paper is to detect insulin resistance (IR) biomarkers via metabolomics. It is important to understand the PCOS pathophysiology, diagnosis measures and, subsequently, to improve treatment type and time of IR in PCOS. In most cases, almost half of the women with PCOS have IR which is triggered by inflammation, glucotoxicity and lipotoxicity. In this work was conducted a systematic review of all the papers that used metabolomics for detecting IR biomarkers in PCOS women. The exclusion criteria were: reviews, study population with women bellow 18 years of age, studies including animals and articles not in English, remaining 4 records. The results from the literature shown that phosphatidylcholines were decreased in IR PCOS women when compared to controls. Nonetheless, trans-2-hexenoylcoa, linoleic acid, leucine, myristic acid and palmitic acid regarding lipid metabolism and tyrosine, lysine, phenylalanine a-aminoadipic acid regarding amino acid metabolism were also corelated to IR in PCOS women when compared with healthy or IR controls. Lactate was the only increased metabolite related to glucose metabolism in IR PCOS women. Metabolic alteration in PCOS women with IR when are compared with controls and results that those are brought by both PCOS and IR. Lyso-phosphatidylcholine have an important pro-inflammatory and altered insulin signaling effect, both alterations being considered hallmarks of PCOS women. Serine hyperphosphorylation of the receptor accentuates IR by decreasing the signaling of insulin receptor. Moreover, high levels of lactate correlated with IR in PCOS women may indicate high muscle glycolysis, hepatic glucose production and peripheral glucose uptake. IR biomarkers in PCOS women were evidenced by metabolomics technique.
