While the pathogenesis of cisplatin-induced kidney injury is complex, the major underlying mechanisms converge on oxidative stress, inflammation, and renal fibrosis [11,17], which may involve major NAD+-dependent redox enzymes, such as mitochondrial complex I, CD38, NNT, NADK, PARP, alpha-keto acid dehydrogenases, and sirtuins. This evidence concerns the gene CD38 and renal fibrosis.
