[PMID: 37413858 DOI: 10.1016/j.tice.2023.102128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 04/24/2023] [Accepted: 06/06/2023] [Indexed: 07/08/2023]
Abstract
AIM This study aims to explore the possible effect of Astragaloside IV (AS-IV) on necrotizing enterocolitis (NEC) neonatal rat models and verify the possible implication of TNF-like ligand 1 A (TL1A) and NF-κB signal pathway. METHODS NEC neonatal rat models were established through formula feeding, cold/asphyxia stress and Lipopolysaccharide (LPS) gavage method. The appearance, activity and skin as well as the pathological status of rats subjected to NEC modeling were assessed. The intestinal tissues were observed after H&E staining. The expression of oxidative stress biomarkers (SOD, MDA and GSH-Px) and inflammatory cytokines (TNF-α, IL-1β and IL-6) were detected by ELISA and qRT-PCR. Western blotting and immunohistochemistry were applied to detect expressions of TL1A and NF-κB signal pathway-related proteins. Cell apoptosis was assessed by TUNEL. RESULTS NEC neonatal rat models were established successfully, in which TL1A was highly expressed and NF-κB signal pathway was activated, while TL1A and NF-κB signal pathway can be suppressed by AS-IV treatment in NEC rats. Meanwhile, inflammatory response in intestinal tissues was increased in NEC rat models and AS-IV can attenuate inflammatory response in NEC rats through inhibiting TL1A and NF-κb signal pathway. CONCLUSION AS-IV can inhibit TL1A expression and NF-κb signal pathway to attenuate the inflammatory response in NEC neonatal rat models.

Yao L, Zhao R, He S, Feng Q, Qiao Y, Wang P, Li J. Effects of salvianolic acid A and salvianolic acid B in renal interstitial fibrosis via PDGF-C/PDGFR-α signaling pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 106:154414. [PMID: 36057144 DOI: 10.1016/j.phymed.2022.154414] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 08/12/2022] [Accepted: 08/21/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Renal interstitial fibrosis (RIF) is the main pathological feature of end-stage renal disease (ESRD) caused by various chronic kidney diseases (CKD), and is closely related to renal dysfunction and patient prognosis. Salvianolic acid A (Sal A) and salvianolic acid B (Sal B), isolated from traditional Chinese medicine Salviae miltiorrhizae, have been confirmed to have anti-fibrotic effects on liver, cardiac and kidney. However, the precise molecular mechanism underlying the nephroprotective effects of Sal A and Sal B, and whether there is a difference between the two in RIF are still unclear. PURPOSE This study investigated the pharmacological effects of Sal A and Sal B in RIF and explore the underlying mechanisms by in vivo and in vitro experiments. METHODS The nephroprotective effects of Sal A, Sal B and Sal A+B were evaluated by assessing the parameters related to kidney function such as renal histology, renal function, urinary protein NAG, urinary β2 microglobulin. In addition, RIF-related markers such as CTCF and Par3 were also detected. Thereafter, the related protein or gene levels of PDGF-C/PDGFR-α signaling pathways, apoptosis and endoplasmic reticulum stress (ERS) were determined by western blot, real-time PCR, flow cytometry or immunofluorescence staining. RESULTS In vivo, the results showed that Sal A, Sal B and Sal A+B partially improved kidney dysfunction, increased the expression of Par-3 and reduced the expression of CTGF, PDGF-C and PDGFR-α. In vitro, the results also showed that Sal A, Sal B and Sal A+B reversed apoptosis and ERS in HSA-induced HK-2 cells via regulating PDGF-C/PDGFR-α signaling pathway. CONCLUSION This article revealed a novel mechanism linking PDGF-C/PDGFR-α signaling pathway to RIF and suggested that Sal A, Sal B and Sal A+B were considered as potential therapeutic agents for the amelioration of RIF.

Abstract
The clinical and experimental study into the effects of Chinese herbal medicines on chronic kidney disease has evolved over the past 40 years with new insight into their mechanism and evidence of their clinical effects. Among the many traditional Chinese herbs examined in chronic renal disease, five were found to have evidence of sufficient clinical efficacy, high frequency of use, and well-studied mechanism. They are: Abelmoschus manihot and Huangkui capsule, Salvia miltiorrhiza and its components (tanshinone II A, salvianolic acid A and B); Rhizoma coptidis and its monomer berberine; Tripterygium wilfordii and its components (triptolide, tripterygium glycosides); Kudzu root Pueraria and its monomer Puerarin. These Chinese herbal medications have pharmaceutical effects against fibrosis, inflammation and oxidative stress and also promote renal repair and regeneration. This article reviews their clinical efficacy, anti-fibrotic effects in animal models, and molecular mechanism of action.

Abstract
Danshen, the dried root of Salvia miltiorrhiza Bge, is a common medicinal herb in Traditional Chinese Medicine, which has been used for the treatment of a number of diseases for thousands of years. More than 2000 years ago, the Chinese early pharmacy monograph "Shennong Materia Medica" recorded that Danshen could be used for the treatment of gastrointestinal diseases, cardiovascular diseases, certain gynecological diseases, etc. Since then, Danshen has been widely used clinically in many different prescriptions for many different diseases, especially for the treatment of cardiovascular diseases. Nowadays, many pharmacological studies about the water-soluble components from Danshen have been reported, especially salvianolic acids. It turned out that salvianolic acids showed strong anti-lipid peroxidation and anti-thrombic activities, and among them, SalAA and SalAB were the most potent. This review focused on the achievements in research of salvianolic acids regarding their bioactivities and pharmacological effects. These studies not only shed light on the water-soluble active components of Danshen and their mechanisms at the molecular level, but also provided theoretical information for the development of new medicines from Danshen for the treatment of cardiovascular and cerebrovascular diseases, inflammatory diseases, metabolic diseases, etc.

Thymoquinone alleviates renal interstitial fibrosis and kidney dysfunction in rats with unilateral ureteral obstruction. Phytother Res 2019; 33:2023-2033. [PMID: 31215078 DOI: 10.1002/ptr.6376] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 03/28/2019] [Accepted: 03/30/2019] [Indexed: 01/08/2023]
Abstract
Unilateral ureteral obstruction (UUO) causes severe renal tubulointerstitial fibrosis. Because of many pharmacologic properties of thymoquinone (TQ), in this study, the effects of TQ against kidney fibrosis and dysfunction were investigated in rats with UUO. Forty male Wistar rats were divided into five groups: Sham operated, UUO, and the animals with UUO treated with losartan, captopril, or TQ. Collagen IV and transforming growth factor (TGF)-β1 expressions, interstitial fibrosis, histological changes, and kidney function were assessed. UUO markedly increased renal expression of TGF-β1 and collagen I and induced interstitial fibrosis (p < .001). Losartan, captopril, or TQ significantly downregulated the expression of these fibrotic markers and interstitial fibrosis (p < .01-p < .001). In UUO group, serum levels of urea and creatinine and protein excretion rate significantly increased, but glomerular filtration rate (GFR) and urine osmolarity showed a significant decrease (p < .001-p < .05). Administration of captopril and TQ caused no significant change in serum urea and protein excretion rate. Unlike losartan and captopril, TQ caused no significant alteration in GFR compared with Day 1. Losartan caused significant increases in serum urea and creatinine but significant decrease in urine osmolarity. TQ could be regarded as a potent therapeutic agent for treatment of UUO-induced kidney fibrosis and dysfunction.

Abstract
Purpose To investigate the protective effects of salvianolic acid A (SAA) on renal
damage in rats with chronic renal failure (CRF). Methods The five-sixth nephrectomy model of CRF was successfully established in
group CRF (10 rats) and group CRF+SAA (10 rats). Ten rats were selected as
sham-operated group (group S), in which only the capsules of both kidneys
were removed. The rats in group CRF+SAA were intragastrically administrated
with 10 mg/kg SAA for 8 weeks. The blood urine nitrogen (BUN), urine
creatinine (Ucr), creatinine clearance rate (Ccr), and serum uperoxide
dismutase (SOD) and malondialdehyde (MDA) were tested. The expressions of
transforming growth factor-β1 (TGF-β1), bone morphogenetic protein 7 (BMP-7)
and Smad6 protein in renal tissue were determined. Results After treatment, compared with group CRF, in group CRF+SAA the BUN, Scr,
serum MDA and kidney/body weight ratio were decreased, the Ccr and serum SOD
were increased, the TGF-β1 protein expression level in renal tissue was
decreased, and the BMP-7 and Smad6 protein levels were increased (all P <
0.05). Conclusion SAA can alleviate the renal damage in CRF rats through anti-oxidant stress,
down-regulation of TGF-β1 signaling pathway and up-regulation of BMP-7/Smad6
signaling pathway.

Abstract
Salvianolic acids, the most effective and abundant compounds extracted from Salvia miltiorrhiza (Danshen), are well known for its good anti-oxidative activity. Danshen has been extensively used as a traditional medicine to treat cardiovascular-related diseases in China and other Asian countries for hundreds of years. Recently, more and more studies have demonstrated that salvianolic acids also have a good effect on the alleviation of fibrosis disease and the treatment of cancer. In vivo and in vitro experiments have demonstrated that salvianolic acids can modulate signal transduction within fibroblasts and cancer cells. It is discovered that the cancer treatment of salvianolic acids is not only because salvianolic acids promote the apoptosis of cancer cells, but also due to the inhibition of cancer-associated epithelial-mesenchymal transition processes. In this article, we review a variety of studies focusing on the comprehensive roles of salvianolic acids in the treatment of fibrosis disease and cancer. These perspectives on the therapeutic potential of salvianolic acids highlight the importance of these compounds, which could be the novel and attractive drugs for fibrosis disease and cancer.

Abstract
The aim of the present study was to investigate the protective effect of salvianolic acid A (SAA) on myocardial ischemia/reperfusion injury in rats. SAA (10 mg/kg) or Tirofiban (60 µg/kg) was administered to rats by jugular vein injection 10 min before the initiation of reperfusion. After 3 h of reperfusion, platelet aggregation was measured using an aggregometer and levels of nitric oxide (NO) were detected using an ultraviolet spectrophotometer. Serum levels of cardiac troponin T (cTnT), creatine kinase isoenzyme MB (CK-MB), p-selectin, interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were also measured 3 and 24 h after reperfusion. Furthermore, morphology of the ischemic myocardium was histopathologically analyzed by hematoxylin and eosin staining, and the infarct area was evaluated by Evans blue and triphenyltetrazolium chloride staining. In rats subjected to reperfusion, it was observed that pretreatment with SAA significantly increased the survival rate (P<0.05), and that increased survival rate was due to a significant decrease in infarct size, as evidenced by significantly reduced serum levels of cTnT and CK-MB (P<0.05). In addition, decreases in infarct size occurred through the inhibition of platelet aggregation and inflammation associated with reperfusion-induced myocardial cell damage, as indicated by reduced serum levels of p-selectin, TNF-α, IL-1β and NO. In conclusion, SAA was protective against myocardial ischemia/reperfusion injury in rats by serving antiplatelet and anti-inflammation roles.

Abstract
Astragaloside IV (AS-IV) is a flavonoid from the plant Astragalus membranaceus (Fisch) Bge that has a wide range of therapeutic effects. The aim of the present study was to examine the effect of AS-IV on rats with necrotizing enterocolitis (NEC) under oxidative stress and inflammation. Newborn Sprague-Dawley rats were induced with NEC by asphyxia and hypothermia applied on 3 consecutive days. The rats were orally administered AS-IV at 25, 50 and 75 mg/kg for 4 days. The results revealed that AS-IV administration prevented NEC-induced decrease in the concentration of malondialdehyde and myeloperoxidase, and increase in the activity of glutathione (GSH) and superoxide dismutase in murine models. AS-IV also inhibited NEC-induced elevation in the levels of interleukin (IL)-6, IL-1β, tumor necrosis factor-α and nuclear factor (NF)-κB. The effects of AS-IV were achieved under inflammation and oxidative stress. Western blotting demonstrated that AS-IV substantially inhibited the phosphorylated (p)-IκBα, NF-κBp65, p-NF-κBp65 protein levels and increased vitamin D3 upregulated protein 1 (VDUP1) and IκBα protein levels. These data indicate that AS-IV may be effective in the protection of NEC-induced ileum degeneration by inhibiting the levels of inflammatory markers and oxidative stress via the regulation of the VDUP1/NF-κB signaling pathway.
