title: [Gene expression of extracellular-signal regulated protein kinase 1/2 and their MAPKKs in hypertrophic scars].
abstract: OBJECTIVE
  To explore the change of extracellular-signal regulated protein kinase 1/2 (ERK1/2) and their mitogen activated protein kinase kinases(MAPKKs) gene expression in normal skins versus hypertrophic scars underlying their biological significances.
  
  
  METHODS
  After total RNAs were isolated from 8 specimens of hypertrophic scars and 8 specimens of normal skins, and then were purified to mRNAs, the gene expression of ERK1/2 and MEK1/2 were examined with reverse transcription-polymerase chain reaction (RT-PCR).
  
  
  RESULTS
  In normal skins, the intensity of gene expression of ERK1/2 and MEK1/2 were weak. In hypertrophic scar, the expression intensities of these 4 genes were 1.1 times, 1.2 times, 2.2 times and 2.5 times of normal skins, respectively. The expression of these 4 genes was significantly elevated in comparison with normal skins.
  
  
  CONCLUSIONS
  The activation of MEK1/2, ERK1/2 gene expression in hypertrophic scars versus in normal skins might be one of the mechanisms controlling the formation of hypertrophic scars.
