title: [Role of phorbol 12-myristate 13-acetate on cytokine expression in JAR trophoblast cell line].
abstract: OBJECTIVE
  To investigate whether phorbol 12-myristate 13-acetate (PMA) modifies the invasive ability of trophoblast cells by regulating their cytokine productions.
  
  
  METHODS
  Reverse transcriptase-polymerase chain reaction was used to examine the effect of PMA on the expression of cytokines which regulated the invasive ability of trophoblast cells.
  
  
  RESULTS
  Prior to PMA treatment, expressions of the cytokins including hepatocyte growth factor (HGF), interleukin (IL)-1beta, insulin-like growth factor (IGF)-II, transforming growth factor (TGF)- beta and vascular endothelial growth factor (VEGF) were all detected in JAR cells, only with the exception of IGF-I. After incubation with 100 nmol/L PMA for 24 h, the cells showed strong expression of IL-1beta, HGF and IGF-II, with reduced expression of TGF-beta2 and TGF-beta3.
  
  
  CONCLUSIONS
  By regulating the autocrine of these cytokines, PMA exercises its effect to enhance the invasive ability of trophoblast or choriocarcinoma cells.
