Anti-atherosclerotic effect of tetrahydroxy stilbene glucoside via dual-targeting of hepatic lipid metabolisms and aortic M2 macrophage polarization in ApoE -/- mice. J Pharm Biomed Anal 2024; 248:116338. [PMID: 38971092 DOI: 10.1016/j.jpba.2024.116338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 05/13/2024] [Accepted: 07/03/2024] [Indexed: 07/08/2024]
Abstract
Tetrahydroxy stilbene glucoside (TSG) is a water-soluble natural product that has shown potential in treating atherosclerosis (AS). However, its underlying mechanisms remain unclear. Here, we demonstrate that an 8-week TSG treatment (100 mg/kg/d) significantly reduces atherosclerotic lesions and alleviates dyslipidemia symptoms in ApoE-/- mice. 1H nuclear magnetic resonance metabolomic analysis reveals differences in both lipid components and water-soluble metabolites in the livers of AS mice compared to control groups, and TSG treatment shifts the metabolic profiles of AS mice towards a normal state. At the transcriptional level, TSG significantly restores the expression of fatty acid metabolism-related genes (Srepb-1c, Fasn, Scd1, Gpat1, Dgat1, Pparα and Cpt1α), and regulates the expression levels of disturbed cholesterol metabolism-related genes (Srebp2, Hmgcr, Ldlr, Acat1, Acat2 and Cyp7a1) associated with lipid metabolism. Furthermore, at the cellular level, TSG remarkably polarizes aortic macrophages to their M2 phenotype. Our data demonstrate that TSG alleviates arthrosclerosis by dual-targeting to hepatic lipid metabolism and aortic M2 macrophage polarization in ApoE-/- mice, with significant implications for translational medicine and the treatment of AS using natural products.

Cocoa powder and fermented jackfruit seed flour: A comparative cell-based study on their potential antioxidant and anti-inflammatory activities after simulated gastrointestinal digestion. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2023; 103:4956-4965. [PMID: 36960787 DOI: 10.1002/jsfa.12568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 02/25/2023] [Accepted: 03/24/2023] [Indexed: 06/08/2023]
Abstract
BACKGROUND Jackfruit seed flour can be used as a cocoa aroma replacer with similar technological properties. The purpose of this study was to investigate the in vivo toxicity and in vitro antioxidant activity of fermented jackfruit seed flour (Fjs) and non-alkaline cocoa powder (Nac). RESULTS Fjs and Nac extracts (Fjs-E and Nac-E) were produced and submitted to in vitro gastrointestinal digestion producing digested fractions named Fjs-D and Nac-D, respectively. Nac-E showed over two-fold higher oxygen radical absorbance capacity (ORAC) than Fjs-E. However, after simulated gastrointestinal digestion (in vitro), there were no significant differences between Nac-D and Fjs-D (P < 0.01). Similarly, the cellular antioxidant activity (CAA) of Nac-D and Fjs-D was not significantly different (P < 0.01). The anti-inflammatory assay in transgenic RAW 264.7 murine macrophages showed that Fjs-E did not affect cell viability up to 300 μg mL-1 (P > 0.05) and reduced by 15% the release of TNF-α (P < 0.05). Fjs-D did not affect cell viability up to 300 μg mL-1 (P > 0.05) and showed 58% reduction of NF-κB activation (P < 0.05), with no effects on TNF-α levels. Treatment with Nac-E up to 300 μg mL-1 did not decrease cell viability (P > 0.05) and reduced the release of TNF-α levels by 34% and 66% at 100 and 300 μg mL-1 , respectively (P < 0.05). Nac-D did not reduce the NF-κB activation or TNF-α levels at any tested concentration. CONCLUSION Collectively, these findings indicate that Fjs is a safe and promising functional ingredient with biological activities even after gastrointestinal digestion. © 2023 Society of Chemical Industry.

Identification of immune-related key genes in the peripheral blood of ischaemic stroke patients using a weighted gene coexpression network analysis and machine learning. J Transl Med 2022; 20:361. [PMID: 35962388 PMCID: PMC9373395 DOI: 10.1186/s12967-022-03562-w] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 07/30/2022] [Indexed: 11/28/2022] Open
Abstract
Background The immune system plays a vital role in the pathological process of ischaemic stroke. However, the exact immune-related mechanism remains unclear. The current research aimed to identify immune-related key genes associated with ischaemic stroke. Methods CIBERSORT was utilized to reveal the immune cell infiltration pattern in ischaemic stroke patients. Meanwhile, a weighted gene coexpression network analysis (WGCNA) was utilized to identify meaningful modules significantly correlated with ischaemic stroke. The characteristic genes correlated with ischaemic stroke were identified by the following two machine learning methods: the support vector machine-recursive feature elimination (SVM-RFE) algorithm and least absolute shrinkage and selection operator (LASSO) logistic regression. Results The CIBERSORT results suggested that there was a decreased infiltration of naive CD4 T cells, CD8 T cells, resting mast cells and eosinophils and an increased infiltration of neutrophils, M0 macrophages and activated memory CD4 T cells in ischaemic stroke patients. Then, three significant modules (pink, brown and cyan) were identified to be significantly associated with ischaemic stroke. The gene enrichment analysis indicated that 519 genes in the above three modules were mainly involved in several inflammatory or immune-related signalling pathways and biological processes. Eight hub genes (ADM, ANXA3, CARD6, CPQ, SLC22A4, UBE2S, VIM and ZFP36) were revealed to be significantly correlated with ischaemic stroke by the LASSO logistic regression and SVM-RFE algorithm. The external validation combined with a RT‒qPCR analysis revealed that the expression levels of ADM, ANXA3, SLC22A4 and VIM were significantly increased in ischaemic stroke patients and that these key genes were positively associated with neutrophils and M0 macrophages and negatively correlated with CD8 T cells. The mean AUC value of ADM, ANXA3, SLC22A4 and VIM was 0.80, 0.87, 0.91 and 0.88 in the training set, 0.85, 0.77, 0.86 and 0.72 in the testing set and 0.87, 0.83, 0.88 and 0.91 in the validation samples, respectively. Conclusions These results suggest that the ADM, ANXA3, SLC22A4 and VIM genes are reliable serum markers for the diagnosis of ischaemic stroke and that immune cell infiltration plays a crucial role in the occurrence and development of ischaemic stroke.

TNFα activation and TGFβ blockage act synergistically for smooth muscle cell calcification in patients with venous thrombosis via TGFβ/ERK pathway. J Cell Mol Med 2022; 26:4479-4491.

Abstract
Venous calcification has been observed in post‐thrombotic syndrome (PTS) patients; yet, the cell types and possible mechanisms regulating this process are still unclear. We evaluated the calcium deposition within the venous wall, the cell type involved in the calcified remodelling of the venous wall after thrombosis and explored possible mechanisms in vitro. Calcium deposition was found in human specimens of superficial thrombotic veins and was co‐localized with VSMCs markers αSMA and TAGLN (also known as SM22α). Besides, the expression of osteogenesis‐related genes was dramatically changed in superficial thrombotic veins. Moreover, the inhibition of the TGFβ signalling pathway after TNFα treatment effectively induced the expression of osteogenic phenotype markers, the calcium salt deposits and the obvious phosphorylation of ERK1/2 and JNK2 in the VSMCs calcification model. Supplementing TGFβ2 or blocking the activation of the ERK/MAPK signalling pathway prevented the transformation of VSMCs into osteoblast‐like cells in vitro. Taken together, VSMCs have an important role in venous calcification after thrombosis. Supplementing TGFβ2 or inhibiting the ERK/MAPK signalling pathway can reduce the appearance of VSMCs osteogenic phenotype. Our findings may present a novel therapeutic approach to prevent of vascular calcification after venous thrombosis.

Abstract
The cytoskeleton is a biopolymer network composed of intermediate filaments, actin, and microtubules, which is the main mechanical structure of cells. Vimentin is an intermediate filament protein that regulates the mechanical and contractile properties of cells, thereby reflecting their mechanical properties. In recent years, the "nonmechanical function" of vimentin inside and outside of cells has attracted extensive attention. The content of vimentin in atherosclerotic plaques is increased, and the serum secretion of vimentin in patients with coronary heart disease is remarkably increased. In this review, the mechanistic and nonmechanistic roles of vimentin in atherosclerosis progression were summarized on the basis of current studies.

Abstract
Alzheimer's disease (AD) is a serious, progressive neurodegenerative disease that involves irreversible neuronal death. Tetrahydroxy stilbene glycoside (TSG) is an active compound extracted from P. multiflorum, a traditional Chinese herbal medicine, but its role in neuroprotection is unclear. Herein, we aimed to validate the effects of TSG on APP/PS1 model mice and the underlying mechanism. RNA-seq was performed to identify differentially expressed genes in APP/PS1 mouse, with PCR and immunohistochemistry used for validation. Experiments were performed after bioinformatic analysis for verification. Neuronal damage was observed by H&E staining. Key proteins involved in the pathway such as CX3CR1, Iba1 and TGF-β were examined by immunohistochemical analysis. The KEGG analysis suggested that these genes might act by multiple pathways to build the pharmacological network of TSG in AD progression. These data provide the credible evidence that TSG improved neuronal damage and regulated neuroprotective mechanisms. Together, our work has detailed the whole and major genes in APP/PS1 model mouse regulated by TSG, and highlighted the anti-inflammatory function of TSG in mediating CX3CR1 and TGF-β as the TGF-β/fractalkine/CX3XR1 signaling pathway, especially in microglia. Moreover, TSG has potential value in synaptic transmission and neurotrophic action on neurodegenerative diseases. In summary, TSG is a promising candidate for preventing and treating the progression of AD.

Tetrahydroxy stilbene glycoside attenuates acetaminophen-induced hepatotoxicity by UHPLC-Q-TOF/MS-based metabolomics and multivariate data analysis. J Cell Physiol 2021; 236:3832-3862.

Abstract
Tetrahydroxy stilbene glycoside (TSG) is a main active compound in Polygonum multiflorum. Acetaminophen (APAP) is a well-known analgesic and antipyretic drug. It is considered to be safe within a therapeutic range, in case of acute intoxication hepatotoxicity occurs. This present study aims to observe TSG-provided alleviation on APAP-induced hepatoxicity in C57BL/6 mice. APAP performs extensive necrosis and dissolves nucleus suggesting liver damage from hepatic histopathology. Serum alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and alkaline phosphatase analysis and liver histological evaluation showed that TSG reduced the hepatotoxicity induced by a toxic dose of APAP. Moreover, TSG alone had no hepatotoxicity. TSG eliminated hepatic glutathione depletion and cysteine adducts formation. It also reduced the expression of interleukin-10 and lowered the production of reactive oxygen species in liver tissues. Luminex was used to detect cytokine production in different groups. Herein, we used an untargeted metabolomics approach by performing ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry on treated mice to identify metabolic disruptions under APAP and TSG. Major alterations were observed for purine metabolism, amino acid metabolism, and fatty acid metabolism. These data provide metabolic evidence and biomarkers in the liver that the ABC transporters, Glycine serine and threonine metabolism, and Choline metabolism in cancer changed the most. These targets of metabolites have the potential to improve our understanding of homeostatic. Meanwhile, these metabolites revealed that TSG can alleviate inflammation caused by APAP and promote the activity of intrinsic antioxidants. In summary, TSG can regulate lipid metabolism, promote the production of antioxidant enzymes, and decrease the inflammatory response.

Abstract
Two new glycosidic acids, evolvulic acids B and C (1 and 2), along with a known one, evolvulic acid A (3), were isolated from the glycosidic acid fraction afforded by alkaline hydrolysis of crude resin glycosides from Evolvulus alsinoides whole plants. Their structures were characterized by the spectroscopic data and chemical evidences. Compounds 1 and 2 are both defined as tetrasaccharides, composed of D-fucose, D-glucose, L-rhamnose or D-galactose units. Their aglycones are identified to be a distinctive 3S,11R,14R-trihydroxyhexadecanoic acid, which is only discovered from E. alsinoides up to now. The cytotoxic and anti-migration activities of compounds 1-3 were also tested.

2, 3, 4', 5-tetrahydroxystilbene-2-0-β-d Glycoside Attenuates Age- and Diet-Associated Non-Alcoholic Steatohepatitis and Atherosclerosis in LDL Receptor Knockout Mice and Its Possible Mechanisms. Int J Mol Sci 2019; 20:ijms20071617. [PMID: 30939745 PMCID: PMC6479705 DOI: 10.3390/ijms20071617] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 03/28/2019] [Accepted: 03/29/2019] [Indexed: 02/07/2023] Open
Abstract
The compound, 2,3,5,4'-tetrahydroxystilbene-2-O-β-d-glucoside (TSG), a primary bioactive polyphenolic component of Polygonum multiflorum exerts numerous pharmacological activities. However, its protective effect against non-alcoholic steatohepatitis (NASH), in the context of metabolic syndrome, remains poorly understood. The aim of the present study is to evaluate the effects of TSG treatment on middle-aged (12-mo-old) male LDLr-/- mice, which were fed a high fat diet for 12 weeks to induce metabolic syndrome and NASH. At the end of the experiment, the blood samples of mice were collected for determination of metabolic parameters. Liver and aorta tissues were collected for analysis, such as histology, immunofluorescence, hepatic lipid content, real-time PCR, and western blot. Our data show that TSG treatment improved the different aspects of NASH (steatosis, inflammation, and fibrosis) and atherosclerosis, as well as some of the metabolic basal characteristics. These modulatory effects of TSG are mediated, at least in part, through regulating key regulators of lipid metabolism (SREBP1c, PPARα and their target genes, ABCG5 and CYP7A1), inflammation (CD68, TNF-α, IL-6 and ICAM), fibrosis (α-SMA and TNFβ) and oxidative stress (NADPH-oxidase 2/4, CYP2E1 and antioxidant enzymes). These results suggest that TSG may be a promising candidate for preventing and treating the progression of NASH.

Abstract
Chronic kidney disease (CKD) is associated with profound vascular remodeling, which accelerates the progression of cardiovascular disease. This remodeling is characterized by intimal hyperplasia, accelerated atherosclerosis, excessive vascular calcification, and vascular stiffness. Vascular smooth muscle cell (VSMC) dysfunction has a key role in the remodeling process. Under uremic conditions, VSMCs can switch from a contractile phenotype to a synthetic phenotype, and undergo abnormal proliferation, migration, senescence, apoptosis, and calcification. A growing body of data from experiments in vitro and animal models suggests that uremic toxins (such as inorganic phosphate, indoxyl sulfate and advanced-glycation end products) may directly impact the VSMCs’ physiological functions. Chronic, low-grade inflammation and oxidative stress—hallmarks of CKD—are also strong inducers of VSMC dysfunction. Here, we review current knowledge about the impact of uremic toxins on VSMC function in CKD, and the consequences for pathological vascular remodeling.

Abstract
The RhoA/ROCK signaling pathway regulates cell morphology, adhesion, proliferation, and migration. In this study, we investigated the regulatory role of RhoA/ROCK signaling on PDGF-BB-mediated smooth muscle phenotypic modulation and vascular remodeling and clarified the molecular mechanisms behind these effects. PDGF-BB treatment induced the activation of RhoA, ROCK, PDGF-Rβ, and the expression of PDGF-Rβ in HA-VSMCs (human aortic vascular smooth muscle cells). PDGF-Rβ inhibition and RhoA suppression blocked PDGF-BB-induced RhoA activation and ROCK induction. In addition, PDGF-BB-mediated cell proliferation and migration were suppressed by PDGF-Rβ inhibition, RhoA suppression, and ROCK inhibition, suggesting that PDGF-BB promotes phenotypic modulation of HA-VSMCs by activating the RhoA/ROCK pathway via the PDGF receptor. Moreover, suppressing both ROCK1 and ROCK2 blocked cell cycle progression from G0/G1 to S phase by decreasing the transcription and protein expression of cyclin D1, CDK2, and CDK4 via JNK/c-Jun pathway, thus reducing cell proliferation in PDGF-BB-treated HA-VSMCs. ROCK1 deletion, rather than ROCK2 suppression, significantly inhibited PDGF-BB-induced migration by reducing the expression of vimentin and preventing the remodeling of vimentin and phospho-vimentin. Furthermore, ROCK1 deletion suppressed vimentin by inhibiting the phosphorylation of Smad2/3 and the nuclear translocation of Smad4. These findings suggested that ROCK1 and ROCK2 might play different roles in PDGF-BB-mediated cell proliferation and migration in HA-VSMCs. In addition, PDGF-BB and its receptor participated in neointima formation and vascular remodeling by promoting cell cycle protein expression via the JNK pathway and enhancing vimentin expression in a rat balloon injury model; effects that were inhibited by treatment with fasudil. Together, the results of this study reveal a novel mechanism through which RhoA/ROCK signaling regulates smooth muscle phenotypic modulation and vascular remodeling via the JNK pathway and vimentin cytoskeleton.

Abstract
Uremia accelerates atherosclerosis, but little is known about affected pathways in human vasculature. This study aimed to identify differentially expressed arterial transcripts in patients with chronic kidney disease (CKD). Global mRNA expression was estimated by microarray hybridization in iliac arteries ( n = 14) from renal transplant recipients and compared with renal arteries from healthy living kidney donors ( n = 19) in study 1. Study 2 compared nonatherosclerotic internal mammary arteries (IMA) from five patients with elevated plasma creatinine levels and age- and sex-matched controls with normal creatinine levels. Western blotting and immunohistochemistry for selected proteins were performed on a subset of study 1 samples. Fifteen gene transcripts were significantly different between the two groups in study 1 [fold changes (FC) > 1.05 and false discovery rates (FDR) < 0.005]. Most upregulated mRNAs associated with cellular signaling, apoptosis, TNFα/NF-κB signaling, smooth muscle contraction, and 10 other pathways were significantly affected. To focus attention on genes from genuine vascular cells, which dominate in IMA, concordant deregulated genes in studies 1 and 2 were examined and included 23 downregulated and eight upregulated transcripts (settings in study 1: FC > 1.05 and FDR < 0.05; study 2: FC > 1.2 and P < 0.2). Selected deregulated gene products were investigated at the protein level, and whereas HIF3α confirmed mRNA upregulation, vimentin showed upregulation in contrast to the mRNA results. We conclude that arteries from CKD patients display change in relatively few sets of genes. Many were related to differentiated vascular smooth muscle cell phenotype. These identified genes may contribute to understanding the development of arterial injury among patients with CKD.

Abstract
The aim of this study was to evaluate the potential effects of 2,3,4′,5-tetrahydroxystilbene-2-O-β-d-glucoside (TSG) on the development of atherosclerotic plaque in ApoE−/− mice, and explore the mechanisms involved. Our data showed that after 8 weeks of treatment, TSG ameliorated serum levels of total cholesterol, triglyceride, and low density lipoprotein cholesterol, and increased serum levels of high density lipoprotein cholesterol in ApoE−/− mice. TSG suppressed hepatic steatosis, the formation of atherosclerotic lesions, and the formation of macrophage foam cells in ApoE−/− mice. Moreover, TSG improved the expressions of hepatic SR-BI, ABCG5, and CYP7A1, and up-regulated the protein expressions of aortic ABCA1 and ABCG1. An in-vitro study showed that TSG promoted macrophage cholesterol efflux and increased the protein expressions of ABCA1 and ABCG1. Our findings provide evidence for a positive role of TSG in preventing atherosclerosis by promoting reverse cholesterol transport. These effects may be achieved by stimulating cholesterol efflux through ABCA1 and ABCG1, promoting SR-BI-mediated cholesterol uptake in the liver, increasing secretion of cholesterol into bile by ABCG5, and improving cholesterol metabolism by the CYP7A1 pathway. In addition, antioxidative and anti-inflammatory effects of TSG may also contribute to its inhibitory effects on atherosclerosis. Further study is needed to investigate whether other potential mechanisms are involved in TSG-mediated atheroprotection.
