ABSTRACT
Matrix metalloproteinases and tissue inhibitor of metalloproteinases play an important role in the regulation of mesangial cell proliferation and may be involved in ischemia-reperfusion injuries. Preservation solutions are thought to diminish the ischemic injury and appropriate choice of the solution should guarantee a better graft function and good prognosis for graft survival. The aim of the study was to examine the effect of preservation solutions UW and EC on the expression of matrix metalloproteinase II and tissue inhibitor of metalloproteinase II genes in rat kidney.The study was carried out on Wistar rat kidneys divided into 3 groups: kidneys perfused with 0.9�0NaCl (control group), with UW, and with EC preservation solution.The results show an enhancement of MMP-2 and TIMP-2 gene expression after 12 min of cold ischemia. This increase was more expressed in kidneys preserved with UW solution in comparison with kidneys perfused with EC solution and 0.9�0NaCl. After 24 h of cold ischemia the expression of MMP-2 and TIMP-2 genes in kidney perfused with UW solution decreased, while in kidneys perfused with EC it was increased. After warm ischemia the MMP-2 and TIMP-2 gene expression increased, whereas it was significantly lower in kidneys perfused with EC solution.
