BACKGROUND 3,5,3-triiodothyronine (T3) was found to decrease ischemia-reperfusion (I/R) injury of liver and myocardium in animal models when preconditioned 48 hours in advance of the I/R injury. The purpose of this study was to evaluate the effects of T3 preconditioning on renal I/R injury with different time intervals and to determine the changes in antioxidants, apoptosis, and nitric oxide synthase (NOS) in each condition. METHODS In male C57BL/6 mice, renal I/R injury was induced by temporary ligation of the bilateral renal pedicles for 45 minutes followed by a reperfusion period for 24 hours. Preconditioning with intraperitoneal injection of T3 was performed 24 or 6 hours before or at the time of I/R injury. RESULTS From the histologic examination, tubular injury was decreased in mice preconditioned with T3 6 hours before I/R injury. The levels of proinflammatory cytokines were decreased with T3 preconditioning, either 6 hours or at the time of I/R injury. The levels of glutathione were increased in all treatment groups. Expressions of neuronal NOS were increased when preconditioned 6 hours before or at the time of I/R injury. The number of apoptotic tubular epithelial cell evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay was decreased when preconditioned immediately before I/R injury. CONCLUSIONS Preconditioning with T3 6 hours or immediately before I/R injury had a protective effect on renal I/R injury. The changes of NOS and antiapoptosis, other than well-known antioxidative properties, may play a role in the effect of short-term preconditioning.

D014284 Triiodothyronine A T3 thyroid hormone normally synthesized and secreted by the thyroid gland in much smaller quantities than thyroxine (T4). Most T3 is derived from peripheral monodeiodination of T4 at the 5' position of the outer ring of the iodothyronine nucleus. The hormone finally delivered and used by the tissues is mainly T3.
