Netrin‐1 has been found to protect kidneys from ischemia/reperfusion injury. In this study, we aimed to address whether the protective effects were mediated through suppression of oxidative stress and neuropeptide Y. Compared to sham‐operated animals, animals after ischemia/reperfusion showed marked kidney damage and significantly increased levels of serum creatinine, blood urea nitrogen, malondialdehyde, and neuropeptide Y. Renal myeloperoxidase activity was elevated in animals with ischemia/reperfusion relative to sham‐operated animals, whereas renal superoxide dismutase activity was reduced. Netrin‐1 pretreatment attenuated ischemia/reperfusion‐induced functional and pathological changes in the kidney. Moreover, the ischemia/reperfusion‐induced changes in the oxidative stress biomarkers and neuropeptide Y were significantly counteracted by prior administration of netrin‐1. Taken together, our data showed that netrin‐1 pretreatment prevented renal ischemia/reperfusion injury, at least partially through reduction of oxidative stress and neuropeptide Y expression. © 2013 Wiley Periodicals, Inc.
