title: [Molecular mechanism of the sensitivity of myocardial cell injury after severe hypoxia].
abstract: OBJECTIVE
  To explore the molecular mechanism of the sensitivity of myocardial cell injury after severe hypoxia.
  
  
  METHODS
  Differential expression of the genes in rat myocardium and skeletal muscles after severe hypoxia for 6 hours was determined by DNA chip containing 4096 mice genes.
  
  
  RESULTS
  There were high expressions of 125 genes in skeletal muscles and 111 genes in myocardial cells after 6 hours of severe hypoxia. Among them, high expression genes in myocardial cells included those encoding apoptosis activator Mtd, complement C3, vascular cell adhesion molecule-1, integrin beta subunit and lipopolysaccharide binding proteins (LBP).
  
  
  CONCLUSIONS
  Activation of apoptosis of myocardial cells and inflammatory mediators played important roles in myocardial cell injury after 6-hour severe hypoxia.
