ABSTRACT
Objective: To determine the expressions of Versican and a distintegrin and metalloprotease with thrombospondin type l motifs (ADAMTS-1) in serum in the polycystic ovary syndrome (PCOS) patients, and to clarify their roles in the pathogenesis of PCOS. Methods: A total of 80 patients with PCOS ( PCOS group) and 100 healthy women (control group) were selected. The heights and body weights of the subjects in two groups were measured; and the body mass index (BMI) was calculated. The levels of serum Versican and ADAMTS-1 of the subjects in two groups were measured by enzyme-linked immunosorbent assay (ELISA) method. The levels of serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), fasting blood glucose (FBG), fasting insulin of the subjects in two groups were detected; insulin resistance was evaluated according to Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). The correlations between Versican, ADAMTS-1 and the metabolic indexes were analyzed by Pearson linear correlation analysis. Results: The serum Versican level of the patients in PCOS group was significantly decreased compared with control group (P=0.004); the serum ADAMTS-1 level was also decreased (P<0.01). The sensitivities, the specificities and the area under receiver operating characteristic (ROC) curve （AUC）of Versican and ADAMTS-1 in prediction of PCOS were 76.74%?vs 63.64% (P=0.018), 52.94% vs 40.73% (P=0.009) and 0675 (0.550-0.795) vs 0.714 (0.601-0.827) (P=0.032), respectively. The correlation analysis showed that in PCOS group the serum level of Versican of the patients was negatively correlated with FBG (r=-0.738, P=0.022), and ADAMTS-1 was negatively correlated with FBG (r=-0.524, P=0.043). Conclusion； Versican and ADAMTS-1 lowly express in the patients with PCOS. They are negatively correlated with the insulin resistance. They may play inhibitory effects in the occurrence of PCOS.
