| Description | To investigate the effects of norcantharidin (NCTD) on tubulointerstitial fibrosis of diabetic nephropathy (DN) in streptozotocin-induced rat model. Sprague-Dawley rats were randomly divided into control group, model group, low-dose NCTD (0.05 mg/kg/day) group, and high-dose NCTD (0.1 mg/kg/day) group. The model group was induced by injection intraperitoneally with 30 mg/kg streptozotocin in 0.1 mol/L sodium citrate solution (pH 4.5), after high-calorie foods were given for 2 months. NCTD was administered daily after the DN rat model was built. Rats were sacrificed at the end of the third and the eighth week; renal fibrosis and the expression of FN, collagen IV, TGF-β1, and calcineurin (CaN) were detected by Masson and immunohistochemistry staining, respectively. Tubulointerstitial fibrosis was observed in DN rats, this kind of pathological changes was ameliorated in NCTD treatment group (p < 0.05). The expressions of FN, collagen IV, and TGF-β1 protein increased in the tubulointerstitial field of DN rats compared with the rats in control group. NCTD treatment could dose-dependently decrease their expression and reverse the fibrotic degree (p < 0.05). Meanwhile, the expression of CaN was detected in tubular fields of normal kidney and increased in the tubulointerstitial field in DN rats. However, NCTD downregulated its expression in a dose-dependent manner (p < 0.05). NCTD could downregulate FN, collagen IV, and TGF-β1 expression in tubulointerstitial fields and attenuate tubulointerstitial fibrosis in the early stage of DN rats. NCTD also alleviated the expression of CaN in tubules in DN. The relationship between the role of NCTD's anti-tubulointerstitial fibrosis and its inhibition to CaN expression remains to be further elucidated. |
