Abstract
Objective: To investigate the expressions of eNOS3 and Ve-cadherin at the first week of reperfused acute myocardial infarction (AMI). Methods:16 of mini-swines (20 to 30 Kg) were randomly assigned to the sham-operated group and the AMI group. Pathologic myocardial tissue was collected at 7-day of LAD reperfusion and assessed by immunofluorescence and laser co-focus microscope scan, in-situ hybridization, real-time quantitative polymerase chain reaction and western blot. Results: At 7-day of reperfusion, the eNOS3 mRNA and protein expressions in the infarcted and marginal areas were lower than those in the normal area and sham-operated area (all P < 0.05), similarly the infarcted and marginal areas had lower Ve-cadherin mRNA expression than the normal area and the sham-operated area (all P < 0.05), and Ve-cadherin protein expression was lower in the infarcted area compared with the marginal area, the normal area and the sham-operated area (all P < 0.05). Conclusion: Lowexpressions of eNOS3 and Ve-cadherin in the salvaged sub-healthy microvascular endothelium of infarcted and marginal areas suggest that endothelial system is impaired at 7-day of reperfused acute myocardial infarction.
