While investigating the mechanisms that could mediate the significant burden of cardiovascular complications observed in persons with chronic kidney disease (CKD) and end stage renal disease (ESRD), we identified a previously unknown protein, which we named renalase (RNLS). Over the past 15 years, our understanding of the biology, physiology, and pathophysiology of RNLS has matured. Here we aim to highlight that RNLS is a bifunctional protein. It metabolizes intracellular nicotinamide adenine dinucleotide (NADH), modulates mitochondrial function, and protects energy metabolism. When secreted outside the cell, independent of its enzymatic properties, it functions as a signaling molecule that mediates resistance to stressful stimuli and promotes cell and organ survival. RNLS has been shown to modulate the severity of acute injury to the pancreas, liver, kidney, and heart. It also protects against the development of chronic injury, and here we highlight the potential use of exogenous RNLS peptide agonists to prevent cisplatin-mediated CKD (CP-CKD).
