摘要: 目的:探讨水通道蛋白7和8(aquaporin 7,AQP7;aquaporin 8, AQP8)的表达与睾丸生精功能的关系,以及人参二醇皂苷(PDS)对睾丸水通道蛋白表达的影响。 方法:4、12周龄Wistar大鼠分为盐水对照组(Con组)(n=6)和PDS腹腔注射组(PDS组)(n=6)。PDS组每日给予PDS腹腔注射(25 mg•kg-1•d-1,1 mL),Con组注射等体积生理盐水,给药2周。采用半定量RT-PCR和Western blotting比较睾丸AQP7与AQP8的mRNA和蛋白质表达水平。 结果:随增龄睾丸AQP7和AQP8 mRNA和蛋白表达明显增高;4周龄大鼠PDS腹腔注射2周后睾丸AQP7和AQP8表达增强,PDS对4周龄大鼠睾丸AQP7蛋白质表达有明显的上调作用,12周龄大鼠接受14 d PDS腹腔注射后其AQP8蛋白质表达水平略有下降。 结论:睾丸AQP7和AQP8的表达随性成熟明显增高;PDS对睾丸水通道表达有明显的调节作用。

Abstract: Objective To investigate the relationship between the expressions of aquaporin 7 (AQP7) and aquaporin 8(AQP8) and the spermatogenesis of rat testis, and the effects of panaxadiol saponins(PDS) on expressions of AQP7 and AQP8. Methods Wistar rats of 4 and 12 weeks old were divided into saline control (Con group) and PDS groups. The rats in PDS group were injected with PDS in abdominal cavity (25 mg•kg-1•d-1,1 mL) every day, and saline was used in Con group with equal volume for 2 weeks. Semi-quantitative RT-PCR and Western blotting were employed to detect the mRNA and protein expression levels of AQP7 and AQP8. Results Expression levels of AQP7 and AQP8 were elevated when the age of rats increased; two weeks after injection of PDS, the expressions of AQP7 and AQP8 were upregulated in 4 weeks old rats, but the expressions of AQP7 and AQP8 in 12 weeks old rats were inhibited. Conclusion The expression levels of AQP7 and AQP8 are increased significantly with the sexual maturation; PDS can regulate the expressions of AQPs in testis.
