Abstract: Background: One of the most commonly used anti-cancer agents, Cisplatin (CDDP) often causes nephrotoxicity by eliciting inflammation and oxidative stress. Golimumab, an anti-TNF biologic, is prescribed for the management of numerous inflammatory ailments like psoriatic and rheumatoid arthritis, ulcerative colitis and ankylosing spondylitis.
Objective: Current study has explored the effects of anti-TNF biologics golimumab on mice due to cisplatin-induced nephrotoxicity.
Method: Renal toxicity was caused by administration of single cisplatin injection at 22 mg/kg by intraperitoneal (i/p) route. Golimumab (24 mg/kg, s.c.) was administered consecutively for 7 days. The parameters such as renal functions, oxidative stress, inflammation, and renal damage were evaluated on the 7th day of experiments.
Results: Cisplatin administration caused nephrotoxicity as shown by a significant elevation of various parameters viz; serum creatinine, neutrophil gelatinase-associated lipocalin (NGAL), urea nitrogen (BUN), and cystatin C. There was a significant rise in urinary clusterin, kidney injury molecule 1 (KIM-1), and β-N-acetylglucosaminidase (NAG) concentrations in the animals treated with cisplatin. The markers of oxidative stress (malondialdehyde, reduced glutathione, and catalase), inflammation (IL-6, TNF-α, IL-10, IL-1β, MCP-1, ICAM-1, and TGF-β1), and apoptosis (caspase-3) were also altered in serum and/or kidneys of cisplatin animals. Further, cisplatin-caused histopathological changes in proximal tubular cells as observed in the H&E staining of renal tissue. Golimumab treatment reduced all markers of kidney injury and attenuated cell death. Golimumab significantly reduced inflammatory cytokines TNFα, IL- 6, MCP-1, IL- 1β, ICAM-1, and TGF-β1 and increased anti-inflammatory cytokine IL-10 in cisplatin-intoxicated mice.
Conclusion: The study’s results suggest that golimumab prevented nephrotoxicity induced by cisplatin- through inhibition of oxidative stress, apoptotic cell death inflammatory response, thus improving renal function.
