OBJECTIVE To investigate the effect of jujuboside A on glomerular cell apoptosis in diabetic rats, and to explore the possible mechanisms. METHODS SD rats were administered with streptozotocin 100 mg · kg-1 to estabilish the diabetic model. Diabetic SD rats received jujuboside A 10 and 20 mg · kg-1 daily for 4 weeks by lavage administration, respectively. The level of glycosylated hemoglobin (GHb) in the blood of each group was measured by fructosamine method. The morphological changes in glomerular cells were observed by PAS staining. Glomerular cell apoptosis was determined by TUNEL staining. The protein expression of Bcl-2 and Bax was detected by immunohistochemistry. The protein expression of cleaved caspase 9 and cleaved caspase 3 was detected by Western blotting. Trans?forming growth factor β1 (TGF-β1) mRNA expression was analyzed by qPCR. RESULTS Compared with model group, jujuboside A 10 and 20 mg·kg-1 treatment significantly reduced the level of GHb in blood (mmol · L- 1: 10.9 ± 0.8 vs 17.5 ± 1.5, P<0.05; 7.6 ± 0.5 vs 17.5 ± 1.5, P<0.05), PAS positive score of glomerular cells (26.8 ± 3.2 vs 36.4 ± 3.8, P<0.05; 18.4 ± 2.1 vs 36.4 ± 3.8, P<0.05) and the apoptosis of glomerular cells〔(8.2±0.8)%vs (17.6±1.8)%, P<0.05;(5.1±0.5)%vs (17.6±1.8)%, P<0.05〕. Moreover, Bcl-2 protein expression in kidney tissues was elevated (P<0.05), whereas Bax (P<0.05), cleaved caspase 9 (P<0.05) and cleaved caspase 3 (P<0.05) protein expression and TGF-β1 mRNA (P<0.05) expression were reduced after jujuboside A administration. CONCLUSION Jujuboside A can prevent glomerular cell apoptosis in diabetic rats, which may be associated with the regulation of mitochondrial apoptotic pathways and TGF-β1 expression.
