Limitation of widely used anti-cancer agent cisplatin for a patient is nephrotoxicity. Nephrotoxicity is presentable in mice by injecting cisplatin at 25 mg/kg with 3 days endpoint. We used the same model to understand the protective role of urolithin A. Cisplatin-induced renal damages measured by histological damage in proximal tubular cells and by the increase in serum neutrophil gelatinase-associated lipocalin (NGAL), blood urea nitrogen (BUN), creatinine and urinary Kidney Injury Molecule-1 (KIM-1). Urolithin A pretreatment reduced all the above renal damage parameters in a significant way. Urolithin A attenuated cisplatin-induced pro-inflammatory cytokine/chemokine tumor necrosis factor α (TNFα), interleukin 23 (IL-23), interleukin 18 (IL-18) and macrophage inflammatory protein 2 (MIP2). Cisplatin-induced CD11b positive macrophages in kidneys reduced by urolithin A. Urolithin A also attenuated cisplatin-induced renal oxidative/nitrative stress, which was measured by lipid peroxidation(4-hydroxy-2-nonenal or 4-HNE protein adducts) and protein nitration. Urolithin A cisplatin-induced kidney injury in mice through the down regulation of inflammatory cytokines/chemokine, immune cells, and oxidative/nitrative stress thus improving cisplatin-induced proximal tubular cell death.
