PURPOSE: Polycystic ovary syndrome (PCOS) is considered one of the most common endocrine disorders with heterogeneity. There are also reports that liver receptor homolog 1 [LRH-1 or nuclear receptor subfamily 5 group A member 2] plays an important role in the reproductive system. But up to now, there are no reports related to the link with PCOS and LRH-1. In this study, we aimed to detect the LRH-1 expression in the ovarian granulosa cell (GC) of PCOS patients and explore the potential relationship between LRH-1 and PCOS.
METHODS: In all, 146 follicular fluid samples were collected in this study, including 72 from PCOS patients and 74 from control patients who underwent intracytoplasmic sperm injection or in vitro fertilization-embryo transfer. The ovarian GCs were extracted from the patient's follicular fluid by magnetic-activated cell sorting method, and real-time quantitative PCR was used to measure the expression of LRH-1 in ovarian GCs. Then we analyzed the correlation between the expression level of LRH-1 and the clinical characteristics of the patient by using Pearson Correlation analysis.
RESULTS: The expression of LRH-1 was significantly higher in PCOS patients ovarian GCs than that in the control patients [(1.38 ± 0.47) vs (1.03 ± 0.32), t = 5.327, p < 0.0001], and it was positively correlated with antral follicles counting (r = 0.3607, p < 0.0001) and the serum anti-Mullerian hormone (r = 0.2662, p = 0.0012), luteotropic hormone (r = 0.2518, p = 0.0022), testosterone (r = 0.2794, p = 0.0006) in all patients. No statistical significance between LRH-1 and body mass index, follicle-stimulating hormone, homeostasis model assessment of insulin resistance, dehydroepiandrosterone sulfate, progesterone.
CONCLUSIONS: Compared with the control group, we found that LRH-1 was highly expressed in the ovarian GCs of PCOS patients. Our study has revealed the relationship between the LRH-1 expression and PCOS, which suggested that LRH-1 may play an important role in ovulation disorders. While this finding provided new ideas for the study of pathogenesis, it also provided a theoretical basis for the clinical diagnosis and treatment for PCOS.
