Abstract Cisplatin (CP) is nephrotoxic, and this side effect is used as an animal model for acute kidney injury (AKI). Earlier research has been focused on CP-induced AKI, with relatively little attention being paid to its ability to progress to chronic kidney disease (CKD) on repeated administration. We aimed here to test the dose dependency of its nephrotoxic actions by comparing various physiological, biochemical, molecular, and histopathological indices using repeated increasing doses of CP in rats. Furthermore, we investigated whether these doses of CP would result in the development of CKD. Biochemical, molecular, and histopathological measurements were conducted in plasma, urine, and/or kidneys of rats treated with increasing doses of CP at 1.6, 3.2, and 4.8 mg kg−1 weekly for four consecutive weeks. These doses induced significant and dose-dependent elevations in most of the measured renal indices. These included increased renal fibrosis, as suggested histopathologically and biochemically by the significant increase in transforming growth factor-β1, significant decrease in actin alpha 2, and variable actions of collagen I and IV. CP also dose-dependently increased nuclear factor (erythroid-derived 2)-like 2 and caspase-3. Multiple repeated doses of CP (1.6 to 4.8 mg kg−1) induced multiple episodes of AKI, leading to CKD after the 4th weekly dose and confirmed that this dosage regimen could be used as an experimental animal model of AKI progressing to CKD. These actions were driven by inflammation, oxidative, and nitrosative stress. Keywords Acute kidney injury . Animal models . Chronic kidney disease . Cisplatin . Fibrosis
Introduction Cisplatin (CP) is a potent inorganic platinum-based antineoplastic drug that is commonly used in the treatment of several types of cancers that include otherwise resistant solid tumors, e.g., lymphomas, stomach, esophagus, pancreas, bladder, Electronic supplementary material The online version of this article (https://doi.org/10.1007/s00210-020-01976-1) contains supplementary material, which is available to authorized users. * Mohammed Al Za’abi [email protected] 1
