摘要: 目的 研究肿瘤坏死因子α(TNF-α)对猪卵泡内膜睾酮分泌及细胞增殖情况的影响,探讨TNF-α在多囊卵巢综合征(PCOS)发病机制中的作用。 方法 在体外培养的猪卵泡内膜细胞培养液中加入TNF-α(10、100和1 000 pg/mL),采用放射免疫分析法(RIA)观察细胞上清液中睾酮浓度的变化,CFDA SE细胞增殖检测试剂盒和流式细胞仪观察TNF-α对卵泡内膜细胞增殖情况的影响。 结果 在体外培养的卵泡内膜细胞培养液中加入TNF-α后,在24、48和72 h 3个时间点分别与空白对照组(TNF-α 0 pg/mL)相比,睾酮水平未见明显变化; 72 h后TNF-α(100和1 000 pg/mL)组卵泡内膜细胞平均荧光强度(MFI)明显低于对照组(分别为53.2±11.59和66.87±14.8,P=0.013;47.55±7.31和66.87±14.8,P=0.001)。 结论 TNF-α没有直接促进睾酮分泌的作用,但却具有促进卵泡内膜细胞增殖的功能,这个功能可能与PCOS患者发生卵巢白膜增厚、卵泡内膜细胞增生病变有关。

Abstract: Objective To study the influence of tumor necrosis factor-alpha(TNF-α) on the secretion of testosterone and the proliferation in theca interna cells,and to investigate the role of TNF-α in the pathogenesis of polycystic ovary syndrome(PCOS).   Methods Different concentrations of TNF-α(10,100 and 1 000 pg/mL) were treated with theca interna cells. The secretion of testosterone in theca interna cells were detected by radioimmunoassay(RIA),and the proliferation of theca interna cells were detected by CFDA SE kit and flow cytometry. Results The testosterone level had no difference among the groups(10,100 and 1 000 pg/mL)and the control group(0 pg/mL)at 24 h,48 h and 72 h in theca interna cells. After 72 h,the mean fluorescence intensities(MFI) in theca interna cells with TNF-α 100 pg/mL and 1 000 pg/mL were obviously lower than those in the control group(53.2±11.59 and 66.87±14.8,P=0.013;47.55±7.31 and 66.87±14.8,P=0.001). Conclusions Although TNF-α does not affect the secretion of testosterone,it can promote the proliferation of theca interna cells. This function may explain that PCOS usually accompanies thick ovarian tunica albuginea and proliferative theca cells.
