Purpose: Polycystic ovary syndrome (PCOS) is considered as one of the most common endocrine disorder with heterogeneity. There are also reports that liver receptor homolog 1 [LRH-1 or nuclear receptor subfamily 5 group A member 2 (NR5A2)] 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 of PCOS patients and explore the potential relationship between LRH-1 and PCOS.
Methods: 146 follicular fluid sample were collected in this study, including 72 from PCOS patients and 74 from control patients who underwent intracytoplasmic sperm injection (ICSI) or in vitro fertilization-embryo transfer (IVF-ET). The ovarian granulosa cells were extracted from the patient's follicular fluid by magnetic-activated cell sorting (MACS) method, and the real-time quantitative PCR (qRT-PCR) was used to measure the expression of LRH-1 in ovarian granulosa cells. Then we analyzed the correlation between the expression level of LRH-1 and the clinical characteristics of patient by using Pearson Correlation analysis.
Results: The expression of LRH-1 was significantly higher in PCOS patients ovarian granulosa cells than that in the control patients [vs(1.38±0.47)vs(1.03±0.32), t=5.327, p<0.0001], and it was positively correlated with antral follicles counting (AFC) (r=0.3607, p<0.0001)and the serum AMH(r=0.2662, p=0.0012)\LH(r=0.2518, p=0.0022)\T(r=0.2516, p=0.0022) in all patients. No statistical significance between LRH-1 and BMI, FSH, HOMA-IR, DHE-S, progesterone.
Conclusions: Compared with the control group, we found that LRH-1 was highly expressed in the ovarian granulosa cells 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 the pathogenesis, it also provided a theoretical basis for the clinical diagnosis and treatment for PCOS.
