title: [Effects of keratinocyte growth factor on the expression and activity of extracellular signal-regulated kinase in Hep-2 cell line].
abstract: OBJECTIVE
  To observe effects of keratinocyte growth factor (KGF) on the proliferation of Hep-2 cell line; the activity and expression of extracellular signal-regulated kinase (ERK).
  
  
  METHODS
  Cell line proliferation was measured by Flow cytometry and MTT assay; ERK activity was measured by ERKl/2 immuno-precipitation kinase assay kit; and p ERK expression was assessed by Western blot.
  
  
  RESULTS
  KGF can improve the proliferation of Hep-2 cell line. The intracellular ERK activity and p-ERK expression were increased by different concentrations of KGF.
  
  
  CONCLUSIONS
  KGF can stimulated proliferation of Hep-2 cell line with enhancing activity of ERK and expression of p-ERK.
