Abstract:
The present work evaluated preventive effect of curcumin on cisplatin‐induced bladder cystopathy. Methods Fifteen female rats were divided into (i) Control group administered with physiological saline solution for 5 days; (ii) Cis‐P group injected with cisplatin (6 mg/kg); and (iii) Cis‐Cur group given cisplatin (6 mg/kg) with curcumin for 5 consecutive days. The function of bladder was measured by means of urodynamic analysis. Furthermore, hematoxylin‐eosin staining and Masson trichrome staining were performed for morphological analysis. The cell apoptosis was evaluated through terminal deoxynucleotidyl transferase‐mediated dUTP‐biotin nick end labeling (TUNEL) assay and flow cytometry. The expression of nerve growth factor (NGF), NF‐E2‐related factor 2, and hemeoxygenase‐1 (HO‐1) levels were measured through Western blotting. Results Urodynamic assay and histopathological manifestations revealed that curcumin ameliorated the bladder dysfunction induced by cisplatin. The level of cisplatin‐induced apoptosis in the bladder decreased following curcumin treatment. Also, the increased protein expression of NGF indicated that the curcumin could offer neuroprotection for bladder against cisplatin. Curcumin also activated NRF2, and elevated the expression of HO‐1, but curcumin could not rescue cisplatin‐induced apoptosis in the cell lines with knockdown of NRF2. Conclusions Taken together, the results of this paper showed that curcumin could ameliorate cisplatin‐induced cystopathy and inhibit the apoptosis of bladder cell in cisplatin‐treated rats. This may be attributed to curcumin's broad biological functions, particularly antioxidant effect, and to its ability to activate the NRF2 protein.
