In the present study, we demonstrated that remote IPC (limb IPC) al-leviates the subsequent renal injury induced by contrast media throughthe mechanisms associated with anti-apoptosis, anti-inflammation andanti-oxidation. We also found that the reno-protective effects of limbIPC against CIN are mediated by renalase upregulation. Furthermore,our results indicate that limb IPC induced renalase expression is regulat-ed via the TNFα/NF-κB, but not HIF-1 pathway. Thus, we suggest thatremote IPC induced renalase upregulation is critically involved in thereno-protective effect in CIN
