摘要: 目的 探究雌激素与星形胶质细胞增殖和侵袭的相关性。方法 体外培养星形胶质细胞系U-87,分别进行0、10-12、10-10、10-8和10-6 mol/L雌激素处理,通过qPCR、Western blot、ELISA、CCK8法以及Transwell小室法分析相关基因、蛋白质表达以及细胞增殖和侵袭功能。结果 相比对照组,雌激素呈浓度依赖性降低细胞因子IL-1β、TNF-α、IL-6的表达,升高NGF、PGE2表达(P<0.05),抑制水通道蛋白2(AQP2)的表达(P<0.05);同时相比对照组,雌激素呈浓度依赖性促进星形胶质细胞的增殖和侵袭(P<0.05),细胞活性显著提高。结论 雌激素下调AQP2的表达,下调细胞因子的表达,升高NGF、PGE2表达,促进星形胶质细胞的增殖和侵袭。

Abstract: Objective To explore the relationships between the estrogen and astrocyte cell proliferation as well as invasion. Methods Astrocyte cell line U-87 was cultured in vitro and treated with 0, 10-12, 10-10, 10-8 and 10-6 mol/L estrogen. The gene and protein expressions were analyzed by qPCR, Western blot, ELISA; and the cell proliferation and invasion was analyzed by CCK-8 kits and transwell experiments. Results Estrogen significantly inhibited IL-1, TNF-α, IL-6 expression and promoted the expression of NGF and PGE2 (P<0.05). Furthermore, estrogen inhibited aquaporin 2(AQP2) expression (P<0.05). The proliferation and invasion experiments showed that estrogen promoted the U-87 cell proliferation and invasion (P<0.05). Conclusions Estrogen down-regulates the expression of inflammatory factors, inhibites the expression of AQP2, promotes the proliferation and invasion of U-87 cells.

Key words: estrogen, astrocyte, aquaporin 2, proliferation
