Polydatin, a glucoside of resveratrol, recently has been demonstrated possibly to exert its biological effects by targeting sonic hedgehog (Shh). However, whether Shh signaling pathway is involved in the therapeutic effects of polydatin for renal ischemia/reperfusion (I/R) injury has not been evaluated. Our results showed that I/R induced the secretion of Shh, upregulated Patched and Smoothened, and enhanced the nuclear translocation and target gene transcription of Glioblastoma 1 in renal I/R injury models, which were further upregulated after the administration of polydatin significantly and in turn exerted prominent nephroprotective effects against cell apoptosis and oxidative stress. The treatment with cyclopamine (a specific inhibitor of Smoothened) or 5E1 (an anti-Shh antibody) not only markedly inhibited the activation of the Shh pathway, but also dramatically suppressed the nephroprotective effects of polydatin above-mentioned. These results advance our knowledge that polydatin can provide protection for kidneys against I/R injury by enhancing antioxidant capacity and decreasing cell apoptosis through activating Shh signaling pathway.
