Task: Question Answering
Input (English): Context: Sedum sarmentosum Bunge, a traditional Chinese herbal medicine, has a wide range of clinical effects, including anti-oxidation, anti-inflammation, and anti-cancer properties. In this study, we determined whether S. sarmentosum Bunge Extract (SSBE) has anti-fibrotic effects on renal tissues.', 'We investigated the effects of SSBE on aristolochic acid (AA)-induced injury to renal tubular epithelial cells (RTECs) in vitro and unilateral ureteral obstruction (UUO)-induced renal fibrosis in vivo by evaluating epithelial-to-mesenchymal transition (EMT) and the accumulation of extracellular matrix (ECM) components. Furthermore, we examined the expression levels of TGF-β1 and its receptor.', 'In cultured RTECs (NRK-52E), AA promoted renal EMT and ECM accumulation by up-regulating the expression of mesenchymal markers and ECM components and by down-regulating the expression of epithelial markers. In addition, AA induced an imbalance between MMP-2 and TIMP-2 and enhanced expression of TGF-β1 and its receptor. SSBE treatment significantly inhibited AA-induced TGF-β1 expression and prevented the induction of EMT and deposition of ECM. In the UUO rats, tubular injury and interstitial fibrosis were obviously increased. SSBE administration protected renal function, as indicated by reduced serum creatinine levels, and alleviated renal interstitial fibrosis. These anti-fibrotic effects were associated with a reduction in TGF-β1 expression and inhibition of EMT and ECM accumulation.\Question: Does sedum sarmentosum Bunge extract exert renal anti-fibrotic effects in vivo and in vitro?
Output (English): These findings suggest that SSBE may have therapeutic potential for fibrotic kidney diseases.
