title: [Compound danshen injection regulated the expression of AQP3 in the human amnion epithelium cells through JNK signal pathway].
abstract: OBJECTIVE
  To explore the role of Compound Danshen Injection (CDI) in regulating the expression of aquaporin 3 (AQP3) in human amnion epithelium cells (hAECs), and to study the relation between c-Jun N-terminal kinase (JNK) signal pathway and AQP3.
  
  
  METHODS
  hAECs were isolated and primarily cultured from term pregnancy with normal amniotic fluid volume and from term pregnancy with oligohydramnios, and then hAECs were further divided into four groups, i.e., the blank control group (A), the SP600125 group (B), the CDI group (C), and the SP600125 +CDI group (D). The cell viability was measured by cell counting kit-8 assay (CCK-8). The expression of total JNK, phosphorylated JNK, and AQP3 were determined by Western blot.
  
  
  RESULTS
  (1) In hAECs with normal AFV or with oligohydramnios: There was no statistical difference in the cell viability or the expression of total JNK among the 4 groups (P > 0.05). But there was statistical difference in the expression of p-JNK (P < 0.05). Compared with A group, the expression of p-JNK was obviously down-regulated in B group, but obviously up-regulated in C group (P < 0.05). The expression of p-JNK was significantly lower in D group than in C group, but higher than that in A group or B group (P < 0.05).The AQP3 expression in the hAECs with normal amniotic fluid volume of C group and D group were higher than that in the A group (P < 0.05). However, there was no statistical difference in the AQP3 expression between C group and D group (P > 0.05). In hAECs with oligohydramnios, the expression of AQP3 obviously decreased in B group, but up-regulated in C group (both P < 0.05). The expression of AQP3 was lower in D group than in C group, but higher than in B group (P < 0.05).
  
  
  CONCLUSIONS
  CDI could regulate the AQP3 expression in hAECs with oligohydramnios via activating the JNK signal pathway.
