title: [Regulation of invasion behavior of ERK-mediated trophoblast by focal adhesion kinase].
abstract: OBJECTIVE
  To investigate the role of focal adhesion kinase (FAK) in extracellular signal-regulated kinase (ERK) signaling pathway mediated invadsion of trophoblasts.
  
  
  METHODS
  We established a human extravillous cytotrophoblasts in vitro invasion model. Different concentrations of herbimycin A(FAK inhibitor)and PD98059 (ERK inhibitor) were given to observe the influence on the growth of trophoblast cells, FAK, ERK phosphorylation, and trophoblast invasion abilities.
  
  
  RESULTS
  The expression of phosphorylated FAK in the extravillous cytotrophoblasts (EVCT) was inhibited by herbimycin A in a concentration-dependent manner and expression of phosphorylated ERK1/2 was also partially reduced. PD98059 had no effect on the expression of phosphorylated FAK. Herbimycin A and PD98059 suppressed the in vitro invasion of EVCT to various degrees.
  
  
  CONCLUSIONS
  ERK signaling pathway may be the common pathway for many invasive signals,and play a key role in the regulation of trophoblast invasion.
