Ginsenoside Rb1 (GRb1),a component derived from medicinal plants,is known for its pharmacological benefits in IS,but its protective effects on BMECs have yet to be explored. This study aimed to investigate the potential protective effects of GRb1 on BMECs. Methods An in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model was established to mimic ischemia-reperfusion (I/R) injury. Bulk RNA-sequencing data were analyzed by using the Human Autophagy Database and various bioinformatic tools,including gene set enrichment analysis (GSEA),Gene Ontology (GO) classification and enrichment analysis,Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis,protein-protein interaction network analysis,and molecular docking. Experimental validation was also performed to ensure the reliability of our findings. Results Rb1 had a protective effect on BMECs subjected to OGD/R injury. Specifically,GRb1 was found to modulate the interplay between oxidative stress,apoptosis,and autophagy in BMECs. Key targets such as sequestosome 1 (SQSTM1/p62),autophagy related 5 (ATG5),and hypoxia-inducible factor 1-alpha (HIF-1α) were identified,highlighting their potential roles in mediating the protective effects of GRb1 against IS-induced damage. Conclusion GRbl protects BMECs against OGD/R injury by influencing oxidative stress,apoptosis,and autophagy. The identification of SQSTM1/p62,ATG5,and HIF-1α as promising targets further supports the potential of GRb1 as a therapeutic agent for IS,providing a foundation for future research into its mechanisms and applications in IS treatment.展开更多

文摘Anti-aging research has become a popular scientific field with the increasing prominence of population aging.Rare ginsenoside Compound K(CK)has attracted widespread attention as an emerging anti-aging active ingredient.The anti-aging effect of ginsenosides is considered to be one of the important roles of ginsenosides,and Compound K,as the main deglycosylated metabolite of ginsenosides,has a comprehensive anti-aging effect as a highly active ingredient obtained by transformation under the action of microbiota.Recent studies have shown that ginsenosides have anti-photo-oxidation,anti-skin aging,free radical scavenging and immunostimulatory effects,which can effectively prevent skin photoaging.With the progress of modern natural medicine extraction technology and the deepening of the research on the anti-skin aging of ginsenosides'high active ingredients,it will promote the development and application of natural product protective skin photoaging preparations.The rare ginsenoside Compound K plays an important role in the improvement of skin health and anti-aging,which is mainly realized by increasing the activity of antioxidant enzymes,inducing the expression of related genes,reducing the content of oxidative damage substances,regulating the immune system,and influencing the expression of cell-cycle regulators and aging genes.A more comprehensive and in-depth study of the molecular mechanism of the anti-aging effect of rare ginsenoside Compound K will be one of the focuses of future research.

文摘The risk of exposure to particulate matter(PM)has been consistently highlighted globally owing to its detrimental effects on the respiratory and cardiovascular systems and in the development of lung cancer.Additionally,PM promotes cancer cell metastasis;however,research elucidating the precise mechanisms underlying this phenomenon and the strategies to inhibit it remains limited.The aim of this study was to elucidate the mechanism underlying PM-induced cancer metastasis and investigate the preventive role of ginsenoside Rg3.We treated macrophages with PM and confirmed an increase in the expression and secretion of chemokines,such as CCL3,CCL4,and CCL5.This effect was mediated by the MAPK and NF-kB pathways,and Rg3 inhibited this process by suppressing chemokine expression.These chemokines regulate the expression of epithelial-mesenchymal transition(EMT)markers in cancer cells,including Snail,Slug,ZEB1,and E-cadherin.The regulated EMT markers increased the motility of cancer cells in vitro.Furthermore,an increase in CCL3,CCL4,and CCL5 in the bronchoalveolar lavage fluid(BALF)was confirmed in a PM inhalation mouse model,and Rg3 reduced PM-induced cancer metastasis.The study findings suggest the potential use of Rg3 as a therapeutic agent to prevent PM-induced cancer metastasis.
文摘Myocardial ischemia(MI)is a pathophysiological condition in which the myocardium is unable to maintain normal cardiac function due to insufficient coronary artery blood and oxygen supply,as well as abnormal myocardial energy metabolism[1].Ginsenoside Rbi(Rbi),one of the most abundant natural ingredients in ginseng and Panax notoginseng,has been proven to protect the heart from MI/reperfusion injury(RI)[2].

文摘Sepsis-induced acute lung injury(ALI)is a major clinical challenge,with limited treatment options and high mortality.Ginsenoside Rb1,a bioactive compound derived from ginseng,has shown promising anti-inflammatory and antioxidative effects.This study is the first to systematically investigate the metabolites of ginsenoside Rb1,specifically F2 and CK,in the context of sepsis-induced ALI modeled by lipopolysaccharide(LPS)administration,a widely used preclinical approach to mimic key inflammatory features of clinical sepsis.Unlike other studies,which primarily focus on ginsenoside Rb1 itself,our research specifically emphasizes the role of its metabolites in this process.We demonstrated that ginsenoside Rb1 significantly improved lung histopathological damage,reduced inflammation,and inhibited cell apoptosis in a sepsis-induced ALI mouse model.Metabolomics and proteomics analyses revealed that Rb1 is metabolized into F2 and CK,which activate the AMP-activated protein kinase(AMPK)/Sirtuin 1(SIRT1)signaling pathway.This activation promotes Forkhead Box O1(FOXO1)deacetylation,inhibiting its cytoplasmic translocation and enhancing mitochondrial unfolded protein response(mtUPR)gene transcription.In vitro experiments confirmed that ginsenoside Rb1 protected alveolar typeⅡ(AT2)cells from oxidative stress and senescence,while restoring mitochondrial function.Blocking the AMPK/SIRT1 pathway or silencing FOXO1 reversed these protective effects,highlighting their crucial roles in Rb1's mitigation of ALI.Our findings provide new insights into the molecular mechanisms by which ginsenoside Rb1 alleviates sepsis-induced ALI and offer a potential therapeutic approach for treating sepsis-related lung injuries.
文摘Objective To study the key technologies in the field of ginsenosides and to offer a guide for the future development ginsenosides through the main path identification method based on genetic knowledge persistence algorithm(GKPA).Methods The global ginsenoside invention authorized patents were used as the data source to construct a ginsenoside patent self-citation network,and to identify high knowledge persistent patents(HKPP)of ginsenoside technology based on the GKPA,and extract its high knowledge persistence main path(HKPMP).Finally,the genetic forward and backward path(GFBP)was used to search the nodes on the main path,and draw the genetic forward and backward main path(GFBMP)of ginsenoside technology.Results and Conclusion The algorithm was applied to the field of ginsenosides.The research results show the milestone patents in ginsenosides technology and the main evolution process of three key technologies,which points out the future direction for the technological development of ginsenosides.The results obtained by this algorithm are more interpretable,comprehensive and scientific.

文摘Coptis chinensis Franch.and Panax ginseng C.A.Mey.are traditional herbal medicines with millennia of documented use and broad therapeutic applications,including anti-diabetic properties.However,the synergistic effect of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng on type 2 diabetes mellitus(T2DM)and its underlying mechanism remain unclear.The research demonstrated that the optimal ratio of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng was 4∶1,exhibiting maximal efficacy in improving insulin resistance and gluconeogenesis in primary mouse hepatocytes.This combination demonstrated significant synergistic effects in improving glucose tolerance,reducing fasting blood glucose(FBG),the weight ratio of epididymal white adipose tissue(eWAT),and the homeostasis model assessment of insulin resistance(HOMA-IR)in leptin receptor-deficient(db/db)mice.Subsequently,a T2DM liver-specific network was constructed based on RNA sequencing(RNA-seq)experiments and public databases by integrating transcriptional properties of disease-associated proteins and protein-protein interactions(PPIs).The network recovery index(NRI)score of the combined treatment group with a 4∶1 ratio exceeded that of groups treated with individual components.The research identified that activated adenosine 5'-monophosphate-activated protein kinase(AMPK)/acetyl-CoA carboxylase(ACC)signaling in the liver played a crucial role in the synergistic treatment of T2DM,as verified by western blot experiment in db/db mice.These findings demonstrate that the 4∶1 combination of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng significantly improves insulin resistance and glucose and lipid metabolism disorders in db/db mice,surpassing the efficacy of individual treatments.The synergistic mechanism correlates with enhanced AMPK/ACC signaling pathway activity.

文摘The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenvironment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

文摘Objective Brain microvascular endothelial cells (BMECs) were found to shift from their usually inactive state to an active state in ischemic stroke (IS) and cause neuronal damage. Ginsenoside Rb1 (GRb1),a component derived from medicinal plants,is known for its pharmacological benefits in IS,but its protective effects on BMECs have yet to be explored. This study aimed to investigate the potential protective effects of GRb1 on BMECs. Methods An in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model was established to mimic ischemia-reperfusion (I/R) injury. Bulk RNA-sequencing data were analyzed by using the Human Autophagy Database and various bioinformatic tools,including gene set enrichment analysis (GSEA),Gene Ontology (GO) classification and enrichment analysis,Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis,protein-protein interaction network analysis,and molecular docking. Experimental validation was also performed to ensure the reliability of our findings. Results Rb1 had a protective effect on BMECs subjected to OGD/R injury. Specifically,GRb1 was found to modulate the interplay between oxidative stress,apoptosis,and autophagy in BMECs. Key targets such as sequestosome 1 (SQSTM1/p62),autophagy related 5 (ATG5),and hypoxia-inducible factor 1-alpha (HIF-1α) were identified,highlighting their potential roles in mediating the protective effects of GRb1 against IS-induced damage. Conclusion GRbl protects BMECs against OGD/R injury by influencing oxidative stress,apoptosis,and autophagy. The identification of SQSTM1/p62,ATG5,and HIF-1α as promising targets further supports the potential of GRb1 as a therapeutic agent for IS,providing a foundation for future research into its mechanisms and applications in IS treatment.

文摘Liver fibrosis is primarily driven by the activation of hepatic stellate cells(HSCs),a process associated with ferroptosis.Ginsenoside Rb1(GRb1),a major active component extracted from Panax ginseng,inhibits HSC activation.However,the potential role of GRb1 in mediating HSC ferroptosis remains unclear.This study examined the effect of GRb1 on liver fibrosis both in vivo and in vitro,using CCl4-induced liver fibrosis mouse model and primary HSCs,LX-2 cells.The findings revealed that GRb1 effectively inactivated HSCs in vitro,reducing alpha-smooth muscle actin(a-SMA)and type I collagen(Col1A1)levels.Moreover,GRb1 significantly alleviated CCl4-induced liver fibrosis in vivo.From a mechanistic standpoint,the ferroptosis pathway appeared to be central to the antifibrotic effects of GRb1.Specifically,GRb1 promoted HSC ferroptosis both in vivo and in vitro,characterized by increased glutathione depletion,malondialdehyde production,iron overload,and accumulation of reactive oxygen species(ROS).Intriguingly,GRb1 increased Beclin 1(BECN1)levels and decreased the System Xc-key subunit SLC7A11.Further experiments showed that BECN1 silencing inhibited GRb1-induced effects on HSC ferroptosis and mitigated the reduction of SLC7A11 caused by GRb1.Moreover,BECN1 could directly interact with SLC7A11,initiating HSC ferroptosis.In conclusion,the suppression of BECN1 counteracted the effects of GRb1 on HSC inactivation both in vivo and in vitro.Overall,this study highlights the novel role of GRb1 in inducing HSC ferroptosis and promoting HSC inactivation,at least partly through its modulation of BECN1 and SLC7A11.

文摘Objective:Ginsenoside Rh1(G-Rh1)has been confirmed to inhibit the growth of breast cancer and colon cancer,but its therapeutic effect on hepatocellular carcinoma(HCC)is unclear.This study investigates the therapeutic effect of G-Rh1 on HCC as well as the underlying mechanism.Methods:Bioinformatics methods were used to analyze glucocorticoid receptor(GR)expression and the tumor microenvironment in HCC tissues from HCC patients.The effect of G-Rh1 on HCC cells was investigated in vitro using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method.The therapeutic effect of G-Rh1 was investigated in vivo using subcutaneous transplantation models in C57BL/6J and nude mice.Additionally,the proportion of infiltrating immune cells in tumors was analyzed using flow cytometry,the GR and major histocompatibility complex class-I(MHC-I)expression of HCC cells after G-Rh1 treatment was analyzed using Western blotting,and G-Rh1-treated Hepa1-6 cells were cocultured with bone marrow-derived dendritic cells and B3Z T cells to further analyze the ability of G-Rh1 to induce dendritic cell(DC)maturation and CD8+T cell activation.Results:GR expression was upregulated in HCC tissues,and high GR expression was associated with a worsened immune microenvironment.In vitro studies showed that G-Rh1 had no significant effect on the proliferation of HCC cells,while in vivo studies showed that G-Rh1 exerted antitumor effects in C57BL/6J mice but not in nude mice.Further research revealed that G-Rh1 ameliorated the immunosuppressive tumor microenvironment,thereby enhancing the antitumor effects of lenvatinib by increasing the infiltration of CD8+T cells,mature DCs,and MHC-I-positive cells.MHC-I was upregulated by G-Rh1 via GR suppression.Moreover,overexpression of GR abolished the G-Rh1-mediated promotion of MHC-I expression in Huh7 cells,as well as the maturation of DCs and the activation of CD8+T cells.Conclusion:G-Rh1 can regulate the immune microenvironment of HCC by targeting GR,thus increasing the antitumor effect of lenvatinib.

文摘Panax notoginseng saponins(PNS)are the main active components of Panax notoginseng.But after oral administration,they need to be converted into rare ginsenosides by human gut microbiota and gastric juice before they can be readily absorbed into the bloodstream and exert their effects.The sources of rare ginsenosides are extremely limited in P.notoginseng and other medical plants,which hinders their application in functional foods and drugs.Therefore,the production of rare ginsenosides by the transformation of PNS using Aspergillus fumigatus was studied in this research.During 50 days at 25℃and 150 rpm,A.fumigatus transformed PNS to 14 products(1-14).They were iso-lated by varied chromatographic methods,such as silica gel column chromatography,Rp-C18 reversed phase column chromatography,semi-preparative HPLC,Sephadex LH-20 gel column chromatography,and elucidated on the basis of their 1H-NMR,13C-NMR and ESIMS spectroscopic data.Then,the transformed products(1-14)were isolated and identified as Rk3,Rh4,20(R)-Rh1,20(S)-Protopanaxatriol,C-K,20(R)-Rg3,20(S)-Rg3,20(S)-Rg2,20(R)-R2,Rk1,Rg5,20(S)-R2,20(R)-Rg2,and 20(S)-I,respectively.In addition,all transformed products(1-14)were tested for their antimicrobial activity.Among them,compounds 5(C-K)and 7[20(S)-Rg3]showed moderate antimicrobial activities against Staphylococcus aureus and Candida albicans with MIC values of 6.25,1.25μg/mL and 1.25,25μg/mL,respectively.This study lays the foundation for production of rare ginsenosides.

文摘Objective:This study investigates the sleep-modulating effects of ginsenoside Rg1(Rg1,C_(42)H_(72)O_(14)),a key bioactive component of ginseng,and elucidates its underlying mechanisms.Methods:C57BL/6J mice were intraperitoneally administered doses of Rg1 ranging from 12.5 to100 mg/kg.Sleep parameters were assessed to determine the average duration of each sleep stage by monitoring the electrical activity of the brain and muscles.Further,orexin neurons in the lateral hypothalamus(LH)and corticotropin-releasing hormone(CRH)neurons in the paraventricular hypothalamic nucleus(PVH)were ablated using viral vector surgery and electrode embedding.The excitability of LH^(orexin)and PVH^(CRH)neurons was evaluated through the measurement of cellular Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog(c-Fos)expression.Results:Rg1(12.5–100 mg/kg)augmented the duration of non-rapid eye movement(NREM)sleep phases,while reducing the duration of wakefulness,in a dose dependent manner.The reduced latency from wakefulness to NREM sleep indicates an accelerated sleep initiation time.We found that these sleep-promoting effects were weakened in the LH^(orexin)and PVH^(CRH)neuron ablation groups,and disappeared in the orexin and CRH double-ablation group.Decreased c-Fos protein expression in the LH and PVH confirmed that Rg1 promoted NREM sleep by inhibiting orexin and CRH neurons.Conclusion:Rg1 increases the duration of NREM sleep,underscoring the essential roles of LH^(orexin)and PVH^(CRH)neurons in facilitating the sleep-promoting effects of Rg1.Please cite this article as:Wang YY,Wu Y,Yu KW,Xie HY,Gui Y,Chen CR,Wang NH.Ginsenoside Rg1 promotes non-rapid eye movement sleep via inhibition of orexin neurons of the lateral hypothalamus and corticotropin-releasing hormone neurons of the paraventricular hypothalamic nucleus.J Integr Med.2024;22(6):719–728.

文摘Objectives:To investigate whether the protective actions of ginsenoside Rb1(Rb1)on astrocytes are mediated through the G_(s)-type G-protein-coupled receptor(GPCR-G_(s)).Methods:Primary astrocyte cultures derived from neonatal mouse brain were used.Astrocyte injury was induced via oxygen-glucose deprivation/re-oxygenation(OGD/R).Cell morphology,viability,lactate dehydrogenase(LDH)leakage,apoptosis,glutamate uptake,and brain-derived neurotrophic factor(BDNF)secretion were assessed to gauge cell survival and functionality.Western blot was used to investigate the cyclic adenosine monophosphate(cAMP)and protein kinase B(Akt)signaling pathways.GPCR-G_(s)-specific inhibitors and molecular docking were used to identify target receptors.Results:Rb1 at concentrations ranging from 0.8 to 5μM did not significantly affect the viability,glutamate uptake,or BDNF secretion in normal astrocytes.OGD/R reduced astrocyte viability,increasing their LDH leakage and apoptosis rate.It also decreased glutamate uptake and BDNF secretion by these cells.Rb1 had protective effects of astrocytes challenged by OGD/R,by improving viability,reducing apoptosis,and enhancing glutamate uptake and BDNF secretion.Additionally,Rb1 activated the cAMP and Akt pathways in these cells.When the GPCR-G_(s) inhibitor NF449 was introduced,the protective effects of Rb1 completely disappeared,and its activation of cAMP and Akt signaling pathways was significantly inhibited.Conclusion:Rb1 protects against astrocytes from OGD/R-induced injury through GPCR-G_(s) mediation.
文摘Aplastic anemia(AA)is a rare but serious condition in which the bone marrow fails to produce sufficient new blood cells,leading to fatigue,increased susceptibility to infection,and uncontrolled bleeding.In this editorial,we review and comment on an article by Wang et al published in 2024.This study aimed to evaluate the potential therapeutic benefits of ginsenoside Rg1 in AA,focusing on its protective effects and uncovering the underlying mechanisms.Cyclophosphamide(CTX)administration caused substantial damage to the structural integrity of the bone marrow and decreased the number of hematopoietic stem cells,thereby establishing an AA model.Compared with the AA group,ginsenoside Rg1 alleviated the effects of CTX by reducing apoptosis and inflammatory factors.Mechanistically,treatment with ginsenoside Rg1 significantly mitigated myelosuppression in mice by inhibiting the mitogen activated protein kinase signaling pathway.Thus,this study indicates that ginsenoside Rg1 could be effective in treating AA by reducing myelosuppression,primarily through its influence on the mitogen activated protein kinase signaling pathway.We expect that our review and comments will provide valuable insights for the scientific community related to this research and enhance the overall clarity of this article.
