Dunnione protects against experimental cisplatin-induced nephrotoxicity by modulating NQO1 and NAD+ levels
2018
AbstractDespite being an efficacious anticancer agent, the clinical utility of cisplatin is hindered by its cardinal side effects. This investigation aimed to appraise potential protective impact of dunnione, a natural naphthoquinone pigment with established NQO1 stimulatory effects, on cisplatin nephrotoxicity of rats. Dunnione was administered orally at 10 and 20 mg/kg doses for 4 d and a single injection of cisplatin was delivered at the second day. Renal histopathology, inflammatory/oxidative stress/apoptotic markers, kidney function, and urinary markers of renal injury were assessed. Dunnione repressed cisplatin-induced inflammation in the kidneys as indicated by decreased TNF-α/IL-1β levels, and reduced nuclear phosphorylated NF-κB p65. This agent also obviated cisplatin-invoked oxidative stress as elucidated by decreased MDA/GSH levels and increased SOD/CAT activities. Dunnione, furthermore, improved renal histological deteriorations as well as caspase-3 activities and terminal deoxynucleotidyl tra...
