目的:探讨Ghrelin基因在卵巢颗粒细胞中的表达及其与多囊卵巢综合征(polycystic ovarian syndrome,PCOS)的关系。方法:选择47例在重庆医科大学辅助生育中心接受体外受精-胚胎移植治疗的不孕妇女,其中PCOS组11例,对照(Non-PCOS)组36例,采用real-time PCR及免疫印迹法分别测定2组妇女卵巢颗粒细胞中Ghrelin mRNA和蛋白的表达水平。结果:PCOS妇女颗粒细胞中Ghrelin mRNA和蛋白的表达均低于Non-PCOS妇女(0.926±0.206 vs. 1.137±0.105,t=2.73,P=0.015;0.647±0.052 vs. 0.937±0.038,t=7.82,P=0.001)。结论:PCOS妇女卵巢颗粒细胞的Ghrelin mRNA和蛋白表达水平明显低于Non-PCOS妇女,可能与卵泡发育障碍相关。
Abstract
Objective:To determine the expression of Ghrelin gene in ovarian granulosa cells(GCs) of patients with polycystic ovarian syndrome(PCOS) and to discuss the relationship between them. Methods:GCs were obtained at the time of oocyte retrieval from a total of 47 women undergoing in vitro fertilization and embryo transfer(IVF-ET) treatment due to male factors or tubal factors. Eleven PCOS women were taken as PCOS group and 36 non-PCOS women as control group. The expression of Ghrelin mRNA was measured by real-time PCR and Western blot was used to detect the expression of Ghrelin protein in GCs. Results:The expression of Ghrelin mRNA in GCs was significantly lower in PCOS group than in control group(t=2.73,P=0.015) and the expression of Ghrelin protein in GCs was also significantly lower in PCOS group than in control group(t=7.82,P=0.001). Conclusion:The mRNA and protein expressions of Ghrelin in GCs are significantly lower in women with PCOS than in non-PCOS women,suggesting that Ghrelin may be involved in the disturbance of follicular development in PCOS.
