Salusins, newly identified regulators of hemodynamics and mitogenesis, increase in polycystic ovarian syndrome.

In the current study, we aimed to investigate whether serum salusin α and β levels are different in PCOS subjects. Fifty women with PCOS and 50 healthy, age- and body mass index matched controls were included to the prospective cross-sectional study. All subjects underwent venous blood drawing on the early follicular phase after an overnight fasting. Serum salusin α and β levels were measured with EIA, and ELISA respectively. The relationships between serum salusin levels and anthropometric and metabolic parameters were also assessed. Plasma salusin α and β levels were higher in women with PCOS compared to control group. Serum salusin α level correlated positively with salusin β and fasting serum insulin levels. The serum salusin β levels were correlated positively with HOMA-IR, TG, LDL-C, LH, FSH, and total testosterone levels. Our results indicate that salusins, newly identified regulators of hemodynamics and mitogenesis, are increased within the serum of women with PCOS.
