MAPK信号通路在复方丹参注射液调节人羊膜上皮细胞AQP3表达中的作用研究
The Role of MAPK Signal Pathway in the Regulation of AQP3 Expression Induced by Compound Danshen Injection in Human Amniotic Epithelial Cells
摘要
Abstract
Objective To investigate the role of m itogen-activated protein kinases (MAPKs)-extracellular signal regulated kinase1/2 (ERK1/2) signal pathway in the regulation of Compound Danshen Injection (CDI) induced AQP3 expression in the human amniotic epithelial cells (hAECs).Methods hAECs of term pregnancy with normal amniotic fluid volume (AFV) or isolated oligohydramnios were primarily cultured.And the cells were equally divided into four groups,i.e.,the vehicle control group,the U0126 group,the CDI group,the CDI + U0126 group.The expressions of phosphorylated ERK1/2 (pERK1/2)and AQP3 in hAECs were detected using Western blot analysis.Results (1) When compared with the control group,the expression level of p-ERK1/2 in hAECs in those with normal AFV and oligohydramnios obviously decreased in the U0126 group (P <0.05).The expression level of p-ERK1/2 could be elevated in the CDI group (P <0.05).The expression level of p-ERK1/2 in hAECs was higher in the CDI +U0126 group than in the U0126 group,but lower in the CDI + U0126 group than in the CDI group (P <0.05).(2) There was no obvious change in AQP3 expression in hAECs with normal AFV between the U0126 group and the vehicle control group (P >0.05).There was no statistical difference in the expression level of AQP3 between the CDI group and the U0126 +CDI group (P >0.05),but they were higher than those in the vehicle control group (P <0.05).(3) Compared with the vehicle control group,the expression level of AQP3 in hAECs with oligohydramnios significantly decreased in the U0126 group and increased in the CDI group (P <0.05).The expression level of AQP3 was lower in the U0126 +CDI group than in the CDI group,but higher in the U0126 +CDI group than in the U0126 group (P <0.05).Conclusion CDI could regulate AQP3 expression level in hAECs with oligohydramnios via activating the MAPK-ERK1/2 signal transduction pathway.关键词
