title: [Follicle stimulating hormone inhibits cisplatin induced apoptosis in ovarian cancer cells].
abstract: OBJECTIVE
  To investigate whether the follicle stimulating hormone (FSH) can inhibit apoptosis in ovarian cancer cells induced by cisplatin (DDP) and its possible mechinism.
  
  
  METHODS
  DNA fragmentation assay, (TdT-mediated dUTP nick end labling TUNEL), Western blot were used to analyze the changes in expression levels of Survivin and bcl-2 protein. The relative activity of caspase-3 was also determined.
  
  
  RESULTS
  200 mIU/ml FSH could regulate down the percentage of apoptotic cells and DNA fragmentation induced by 5.0 micrograms/ml cisplatin, while 200 mIU/ml FSH increased Survivin protein expression but could't influence the expression of bcl-2 protein.
  
  
  CONCLUSIONS
  FSH can inhibit ovarian cancer cells apoptosis induced by cisplatin. The possible mechinism is up-regulation of Survivin expression and down-regulation of caspase activity.
