- Abstract
Objective: Acteoside (ACT) has been reported to regulate the inflammation and immune response. The study aims to explore the effect of ACT on renal fibrosis in unilateral ureteral obstruction (UUO) rats. Methods: Eighteen Sprague-Dawley rats were randomly divided into 3 groups: sham group, opened the abdominal cavity and sutured abdominal; UUO group, performed UUO surgery; and ACT + UUO group, ACT (40 mg/kg) was given by gavage every day after UUO surgery. After 2 weeks of rat model construction, urine and blood samples were collected for biochemical analysis, while kidney tissues were harvested for hematoxylin and eosin (H&E), Masson's trichrome, and immunohistochemistry staining. The expression of connective tissue growth factor (CTGF), alpha smooth muscle actin (α-SMA), collagen III, heat shock protein 47 (HSP47), and β-catenin in the renal tissue was detected and the correlation between these proteins was analyzed. Results: ACT improved the parameters of renal function in UUO rats, including decreased creatinine and urea nitrogen, and declined urinary protein. Pathological analysis suggested that ACT improved the conditions of renal tubule lesion (including structure destruction, atrophy and lumen obstruction), renal interstitial fibrosis and inflammatory cell infiltration in UUO rats. It also down-regulated the expressions of fibrin-related proteins β-catenin, CTGF, α-SMA, collagen III, and HSP47. Correlation analysis found that β-catenin and CTGF were correlated with the expressions of α-SMA, collagen III, and HSP47. Conclusions: ACT could alleviate renal fibrosis in UUO rats probably via inhibiting β-catenin/CTGF signaling pathway.
