title: [Genistein suppresses growth stimulatory effect of growth factors in HCE 16/3 cells].
abstract: OBJECTIVE
  The role of genistein in the effect of growth factors (KGF and EGF) on the growth of HPV 16 DNA-immortalized human cervical epithelial cells (HCE 16/3 cells) was studied.
  
  
  METHODS
  Genistein affected the modulation effect of the growth factors on the growth of HCE 16/3 cells using [3H]-thymidine incorporation, immunocapture assay of uPA and tyrosine kinase assay.
  
  
  RESULTS
  The growth factors stimulated growth of HCE 16/3 cells in serum-free medium. However, genistein suppressed the growth stimulatory effect of growth factors on HCE 16/3 cells and also reduced KGF-enhanced uPA secretion in this cell line. The inhibitory effects might be associated with its attenuation of activity of tyrosine kinases of growth factors.
  
  
  CONCLUSIONS
  The results suggest that genistein have potential value in the prevention and treatment of some tumors in vivo.
