title: [Effects of endothelial lipase on mRNA expression of adhesion molecule of human umbilical vascular endothelial cells].
abstract: OBJECTIVE
  To explore the relationship between human umbilical vascular endothelial cells (HUVECs) and endothelial lipase (EL), and the effect of EL on expression of endothelial cell adhesion molecule (ICAM).
  
  
  METHODS
  HUVECs was treated with tumor necrosis factor-alpha(TNF-alpha) 10 microg/L and the mRNA of adhesion molecules [intercellular adhesion molecule-1 (ICAM-1), vascular cellular adhesion molecule-1 (VCAM-1) and E-selectin] were detected by reverse transcription-polymerase chain reaction (RT-PCR). Then the effect of 50 microg/L anti-endothelial lipase (anti-EL) antibody on the influence of TNF-alpha on these adhesion molecules was observed.
  
  
  RESULTS
  After being treated with TNF-alpha, the mRNA of adhesion molecules expressed by HUVECs were significant up-regulated, there was significant difference compared with control group (all P<0.01). These effects of TNF-alpha were significantly abolished by 50 microg/L anti-EL antibody (P<0.05 or P<0.01).
  
  
  CONCLUSIONS
  EL can affect the expression of adhesion molecules on endothelial cell adhesion molecule. This effect of EL may play a role in the pathophysiologic process in the pathogenesis progress of atherosclerosis.
