| 摘 要： | 目的:检测cathepsin D蛋白在多囊卵巢综合征(polycystic ovarian syndrome,PCOS)患者卵巢组织中的表达。方法:采用Western blot免疫印迹法检测卵巢组织中cathepsin D蛋白的表达,并进行半定量分析;免疫组织化学法观察cathepsin D蛋白的分布定位。结果:PCOS组患者卵巢中cathepsin D蛋白表达显著低于对照组(2.06±0.39 vs 4.76±1.43,P<0.05);cathepsin D在卵泡和卵巢间质细胞上均有表达,其中在卵泡颗粒细胞上染色最深,主要定位在胞浆和胞膜。结论:cathepsin D蛋白在PCOS患者卵巢组织中表达水平显著下调,这可能是PCOS卵泡发育异常的机制之一。

| Abstract: | OBJECTIVE: To investigate the expression of cathepsin D in ovary of patients with polycystic ovarian syndrome (PCOS). METHODS: Western blot was performed to detect the expression of cathepsin D and immunohistochemistry was used to detect the protein distribution in ovarian tissue. RESULT: Semi-quantity values of cathepsin D expression in PCOS and control group were 2.06 +/- 0.39 and 4.76 +/- 1.43 (P<0.05), respectively. Immunostaining for cathepsin D was obvious in both follicles and stromal cells, and the strongest immunostaining was seen in granulosa cells of follicles. Immunochemical study showed the protein was mainly located on the cytoplasm and cell membrane. CONCLUSION: Cathepsin D expression is down-regulated in ovaries of PCOS patients, which may provide a clue for the abnormality of follicle development in PCOS. |
