Abstract

Catalase is an intracellular antioxidant enzyme that is mainly located in cellular peroxisomes and in the cytosol. This enzyme plays a significant role in the development of tolerance to oxidative stress in the adaptive response of cells and tissues. The aim of the present study was to examine the association between the -262C/T polymorphism in the catalase gene and delayed graft function (DGF), acute rejection and chronic allograft nephropathy of kidney allografts. One hundred eighty-seven recipients of first renal transplants were included in the study. The histories of the patients were analysed regarding DGF, acute rejection and chronic allograft nephropathy. The polymorphism -262C/T in the catalase gene was analysed using the polymerase chain reaction--restriction fragment length polymorphism (PCR-RFLP) method. The risk of DGF was significantly lower in T allele carriers compared with CC homozygotes: odds ratio = 0.34, 95% confidence interval = 0.17-0.67, P = 0.001. There were no statistically significant associations between the studied polymorphism and acute rejection or chronic allograft nephropathy. The results of this study suggest that -262C/T polymorphism in the catalase gene is associated with DGF in kidney allogra...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
