Abstract:
Objective To explore the effects of overexpression of hypoxia inducible factor 1? (HIF 1?) mRNA on vascular endothelial growth factor (VEGF) and novoendotheliasis in venous autografts Methods Wistar rats were randomly divided into two groups with 28 rats in each group A rat experimental model of autogenous vein graft was established by transplanting the right external jugular vein into between the interrupted right common carotid artery The transplanted vein in the experimental group was first immersed into a solution containing recombinant adeno associated virus (rAAV) HIF 1? for 45 minutes Vein grafts and blood simples were taken at 7 or 14 days after transplantation RT PCR, ELISA, immunohistochemistry were used to detected HIF 1? mRNA and VEGF expression Results HIF 1? mRNA and VEGF protein remarkably increased in experimental group, and serum level of E selectin significantly decraesed at day 14 The novoendotheliasis and myo endothelium junction in vein grafts were remodeled at day 14 in the experimental group Conclusion Re establishment of the structure and function of the autograft vein graft endothelium was accelerated by overexpressed HIF 1? mRNA
