Salvianolic Acid C Inhibits the Epithelial-Mesenchymal Transition and Ameliorates Renal Tubulointerstitial Fibrosis.
    Frontiers in bioscience (Landmark edition), 2023, 06-27, Volume: 28, Issue:6

    Salvianolic acid C (SAC) is a natural compound derived from. Models for unilateral ureteral obstruction (UUO) and aristolochic acid I (AAI) were established in mice to study renal tubulointerstitial fibrosis. Rat kidney fibroblasts (NRK-49F) and human kidney epithelial cells (HK2) were used as cellular models to evaluate the effects of SAC on kidney fibrosis.. Treatment with SAC for two weeks reduced the level of renal tubulointerstitial fibrosis in UUO- and AAI-induced fibrotic kidneys, as demonstrated by Masson's staining and Western blot. SAC inhibited extracellular matrix protein expression in NRK-49F cells and TGF-β-stimulated HK2 cells in dose-dependent fashion. Moreover, SAC inhibited the expression of epithelial-mesenchymal transition (EMT) factors in animal and cellular models of kidney fibrosis, as well as the EMT-related transcription factor snail. Furthermore, SAC inhibited the fibrosis-related signaling pathway Smad3 in the fibrotic kidneys of two mouse models and in renal cells.. We conclude that SAC inhibits EMT and ameliorates tubulointerstitial fibrosis through involvement of the signaling pathway for transforming growth factor-β (TGF-β)/Smad.

Effect of salvianolic acid A and C compatibility on inflammatory cytokines in rats with unilateral ureteral obstruction.
    Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan, 2015, Volume: 35, Issue:5

    To investigate the effect of salvianolic acid A and C component molecules, which are involved in drug compatibility, on inflammatory cytokine expression that affects human chemokine ligand 5 (CCL5) and chemokine ligand 10 (CXCL10) levels in rats with unilateral ureteral obstruction (UUO).. Fifty Sprague Dawley rats were randomly divided into five groups: normal, model, salvianolic acid A, salvianolic acid C and salvianolic acid A and C groups. The normal group was used as the control, and the other groups of rats had a UUO model established. The control group had free access to food and water, and the other groups received the corresponding drugs for 2 weeks. After the last administration, urine β2-microglobulin (β 2-MG) and N-acetyl-β-D-glucosaminidase (NAG) levels were analyzed. After 24 h, all rats were sacrificed and the serum was analyzed for creatinine (Cr) and blood urea nitrogen (BUN) levels. Rat kidneys were removed, and CCL5 and CXCL10 inflammatory cytokine mRNA expression was measured using real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-PCR). Kidney fibrosis was observed using hematoxylin-eosin (HE) staining and Masson trichrome staining.. In the salvianolic acid A and salvianolic acid C treatment groups, serum Cr and urine NAG levels were significantly lower than in the model group (both P < 0.05). In all treatment groups, urine β2-MG levels were significantly lower than in the model group (all P < 0.05). Compared with model group, the pathological changes and collagen deposition improved to varying degrees (both P < 0.05). CCL5 and CXCL10 mRNA expression decreased to different degrees compared with the model group (both P < 0.05).. Salvianolic acid A and C are component molecules of drug compatibility, and they may protect renal function and improve tubular function and renal pathology to a certain degree in UUO. This improvement may be related to a reduction in inflammatory cytokines CCL5 and CXCL10 secretion in the UUO rat kidney.
