Abstract

Background: Brain death (BD) and the subsequent ischemia/reperfusion (I/R) injury have cardinal implications for the pathogenesis of kidney transplantation (Tx). However, the precise mechanistic pathway of BD and the subsequent I/R injury are unknown. In this study, we performed genome-wide analysis for differential gene expression in kidney isografts from BD donors. Their gene expressions were compared with those from living sources. Methods: Kidneys from BD rats were engrafted and their gene expressions were compared with those from living controls. Donors were intubated, and mechanically ventilated for 6 hours. Grafts were harvested 6 hours after BD, and 1 hour after engraftment. The expression profile of approximately 20,500 genes was analyzed. Results: Gene expression of chemokines (Scya2 and Gro1), cytokines (IL-1 and -6) and adhesion molecules (E- and P-selectin and ICAM-1) were upregulated in the BD kidneys and 1 hour after engraftment. An antiapoptotic gene (Birc2), IκB-ζ, and protective gene (HO-1) wee also upregulated. Other upregulated genes included oncogenes (lipocalin2, Bcl3, and CCAAT/enhancer binding protein δ), Calgranulin B, DEXRAS1, insulin-like growth factor binding protein-1, inhibin β-B-subunit gene, IgG Fc receptor, and FK 506 binding protein 5. We also observed downregulation of the genes Amphiphsin, Jagged 1, Pace 4, Slc15a2, Kcnn2, and gap junction membrane channel protein α5 only in kidneys from BD donors. Conclusions: This is the first demonstration of global gene expression analysis using the rat brain-death isograft model. These results provide new insights for the detection of novel target genes for treatment and prognosis of grafts from brain-dead and extended marginal donors.
