OBJECTIVE: To investigate the correlation between endometrial receptivity with expressions of interleukin-1 (IL-1) and vascular endothelial growth factor (VEGF) in rats with polycystic ovary syndrome (PCOS).
MATERIALS AND METHODS: A total of 24 female Sprague-Dawley (SD) 21 days old were randomly divided into control group (n=12) and PCOS group (n=12). Rats in the control group were normally raised, and PCOS model was established in rats of the PCOS group. All the rats were sacrificed when they grew to 80 days old. Immunohistochemistry was applied to detect the expressions of IL-1 and VEGF. Western blotting was performed to measure the relative expressions of IL-1 and VEGF proteins. Quantitative Polymerase Chain Reaction (qPCR) was utilized to determine the relative messenger ribonucleic acid (mRNA) expressions of IL-1 and VEGF. Data related to endometrial receptivity were detected.
RESULTS: The expression levels of IL-1 and VEGF in the PCOS group declined markedly compared with those in the control group, and the differences were statistically significant (p<0.05). PCOS group had notably lower protein expressions of IL-1 and VEGF than the control group, with statistically significant differences (p<0.05). The mRNA expressions of IL-1 and VEGF in PCOS group were significantly lower than those in the control group, displaying statistically significant differences (p<0.05). Compared with that in the control group, the endometrial receptivity of rats in the PCOS group was reduced evidently, and the difference was statistically significant (p<0.05). Both IL-1 and VEGF had positive correlations with the endometrial receptivity.
CONCLUSIONS: Both IL-1 and VEGF are positively correlated with the endometrial receptivity in the case of PCOS, which can serve as therapeutic targets for PCOS and improve endometrial receptivity in the future.
