Abstract
BackgroudThe glycogen synthase kinase-3β inhibitor thiadiazolidinone derivative 8 (TDZD-8) has been reported to reduce renal ischemia reperfusion (I/R) injury through inhibiting cell damage. However, it is not known whether TDZD-8 could also play a role in protecting the kidney in rat kidney transplantation with renal cold I/R. The aim of the present study was to explore the possible role of TDZD-8 in protecting renal damage in a cold I/R model of rat kidney transplantation. MethodsThe rat model of kidney transplantation with renal cold I/R was established. The renal tissue pathomorphologic changes, renal function, oxidative stress, and inflammatory response were evaluated by detection of a series of indices by hematoxylin and eosin staining, commercial kits, enzyme-linked immunosorbent assay, and spectrophotofluorometry, respectively. ResultsCompared with I/R and Graft groups, renal function was significantly improved in TDZD and TDZD-G groups, which were accompanied by the reduction of renal injury, oxidative stress, and inflammation. ConclusionsThese results suggest that preconditioning with glycogen synthase kinase-3β inhibitor can attenuate kidney transplantation with renal cold I/R through regulating endogenous antioxidant activity and inflammation.
