Candesartan protects from cisplatin-induced kidney damage via the GDF-15 pathway
Özet
OBJECTIVE: The aim of this study was to explore the protective effect of candesartan against cisplatin-induced kidney damage, with a specific focus on the growth differentiation factor 15 (GDF-15) pathway. MATERIALS AND METHODS: 24 adult female Wistar rats, with a weight range of 200-210 grams, were enrolled in the study. Eight rats were included as a normal control group and did not receive any medication. 16 rats were administered cisplatin at a dosage of 2.5 mg/kg/day twice a week for 4 weeks (total dose 20 mg/kg). Then, they were randomly divided into two groups and treated with 1 ml/kg/day tap water or 8 mg/kg/day candesartan via oral gavage daily for 4 weeks. At the end of the treatment period, animals were sacrificed, and their kidneys were assessed histologically. In addition, plasma malondialdehyde (MDA), tumor necrosis factor-? (TNF-?), interleukin-6 (IL-6), creatinine, and GDF-15 levels were assessed. RESULTS: Treatment with candesartan resulted in a significant rise in serum GDF-15 levels and a significant reduction in levels of serum MDA, TNF-?, IL-6, and creatinine compared to the cisplatin and saline group. Candesartan treatment effectively protected the kidney injury, and histopathological examinations of the kidneys confirmed these results. CONCLUSIONS: This study demonstrates that candesartan alleviates cisplatin-induced renal toxicity by further increasing GDF-15, down-regulating inflammatory markers, and reducing oxidative stress. © 2024 Verduci Editore s.r.l.
