title: [Expression and significance of Skp2 and p27kip1 protein in pathological scar].
abstract: OBJECTIVE
  To study the expression of Skp2 gene (s-phase kinase associated protein 2) in the pathological scars and its relationship with p27kip1 level and to investigate its role and its probable mechanism in the pathogenesis of abnormal scars.
  
  
  METHODS
  Immunohistochemical technique was performed to detect the expression and distribution of Skp2 and p27kip1 protein in hypertrophic scar (42 cases), keloid (18 cases), normal scar (40 cases) and normal skin (50 cases), statistics was used to analyze the data.
  
  
  RESULTS
  The positive rate of Skp2 and p27kip1 protein expression was not statistically different between the hypertrophic scar and keloid (P > 0.05), while they were all remarkably significant in comparison between normal scar and abnormal scar (P < 0.05). In pathological scar the protein of Skp2 and p27kip1 showed a strong inverse correlation (P < 0.01).
  
  
  CONCLUSIONS
  The result indicated that the expression of Skp2 was increased and it may lead to decrease p27kip1 level in the hypertrophic scar and keloid, Skp2 overexpression might play an important role in the proliferation of fibroblasts and in the pathogenesis of pathological scar by adjusting the regulation of cyclins such as p27kip1.
