OBJECTIVES: A method to compensate for donor shortages could be donation after cardiac death. In this study, we considered endothelial cell-specific molecules, claudin-5 and VE-cadherin, as possible biomarkers predicting lung injury against warm ischemia. We investigated how the expression of these molecules could change after cardiac arrest in a mouse lung, comparing other molecules presumably relating with ischemia. METHODS: At given intervals after cardiac arrest, the lungs were harvested. Quantitative analysis of mRNA expression of claudin-5, VE-cadherin, IL-1beta, IL-10, HIF-alpha, Egr-1, VEGF, Ang-1 and Ang-2 genes in lung tissues with several periods of warm ischemia was performed. RESULTS: Regarding endothelial cell-specific molecules, there were significant differences in both claudin-5 and VE-cadherin mRNA expression between 0 h and 4 h after cardiac arrest. IL-1beta mRNA expression 1 h, 2 h and 4 h after cardiac arrest increased significantly, compared with that at 0 h. There were no significant differences with the other genes. CONCLUSIONS: We found that it took more time for claudin-5 and VE-cadherin mRNA expression to change significantly than IL-1beta mRNA expression; therefore, endothelial cell-specific molecules, claudin-5 and VE-cadherin, might be no better candidates for clinical use than IL-1beta.
