SCUBE Proteins in Polycystic Ovary Syndrome (IPSOS)

This study investigates circulating levels of SCUBE-1 and SCUBE-3 proteins in women with polycystic ovary syndrome (PCOS) compared with healthy controls. Differences between normoinsulinemic and hyperinsulinemic PCOS subgroups will be evaluated, as well as correlations with clinical and metabolic parameters related to inflammation and cardiovascular risk.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and is frequently associated with insulin resistance, chronic low-grade inflammation, and increased cardiovascular risk. SCUBE proteins (Signal peptide-CUB-EGF domain-containing proteins) are recently identified molecules involved in inflammation, angiogenesis, and platelet activation. Their role in PCOS has not been fully elucidated. This interventional, non-randomized study will measure circulating SCUBE-1 and SCUBE-3 levels in women with PCOS and healthy controls. PCOS patients will be stratified into normoinsulinemic and hyperinsulinemic subgroups based on previously performed metabolic assessments. Blood samples will be collected during routine clinical practice and analyzed using ELISA assays. The study aims to assess SCUBE proteins as potential biomarkers of inflammation and cardiovascular risk in PCOS.
