- Introduction: mRNA changes in the small intestine in response to acute mesenteric ischaemia (AMI) could offer novel diagnostic possibilities, but have not been described. The aim was to characterize the mRNA response to experimental AMI. Materials and methods: Twelve pigs underwent catheterization of the superior mesenteric artery with injection of polivinylalcohol embolization particles or sodium chloride. Laparotomy and intestinal tissue sampling was performed. Microarray analysis was performed using the GeneChip® whole porcine genome array. Results: Seven down-regulated cellular pathways were associated with protein, lipid and carbohydrate metabolism. Seventeen up-regulated pathways were associated with inflammatory and immunological activity, regulation of extracellular matrix and decreased cellular proliferation. Thrombospondin(THS), Monocyte Chemoattractant Protein 1(MCP-1) and Gap Junction Alpha 1(GJA-1) were consistently up-regulated in all embolized pigs. Genes encoding earlier proposed biomarkers for AMI were up-regulated, such as lactate dehydrogenase and creatine kinase, or down-regulated, such as intestinal fatty acid binding protein and glutathione S-transferase. Conclusion: This study describes the intestinal tissue response on a gene expression level to AMI. THS, MCP-1 and GJA-1 were consistently up-regulated by ischemia, whereas earlier proposed biomarkers for AMI were not. Gene expression may not be directly linked to the use of the corresponding proteins as potential clinical biomarkers.
