Atrial fibrillation is a type of cardiac arrhythmia that appears as a common finding during medical examinations in humans, large breed dogs and horses. Clinical presentations are of a particular value in racehorses in high performing activities. Atrial fibrillation is characterized by an irregular heart rhythm, secondary to a primary disease or without any sign of comorbidity. The generation and maintenance of Atrial Fibrillation requires a substrate. Some breeds have a genetic predisposition to developing Atrial Fibrillation. Most cases of Atrial Fibrillation are of the paroxysmal type and self-regulate within a few hours to days without the need for treatment. The focus of this study is on the arrhythmic agents that are used for the treatment of Atrial Fibrillation, therefore other arrhythmic agents may not be included, or are included to demonstrate their effect on increasing, inhibiting or decreasing efficacy when used together with medications for the treatment of Atrial Fibrillation. The “working horse” for the pharmacological treatment of Atrial Fibrillation is Quinidine.展开更多

文摘Objective This study aimed to investigate the effect and underlying mechanism of Fructus lycii in improving exercise fatigue.Methods A network pharmacological approach was used to explore potential mechanisms of action of Fructus lycii.Skeletal muscle C2C12 cells and immunofluorescence were employed to verify the effect and mechanism of the representative components in Fructus lycii predicted by network pharmacological analysis.Results Six potential active components,namely quercetin,β-sitosterol,stigmasterol,7-Omethylluteolin-6-C-beta-glucoside_qt,atropine,and glycitein,were identified to have potency in improving exercise fatigue via multiple pathways,such as the PI3K-Akt,neuroactive ligand-receptor interaction,IL-17,TNF,and MAPK signaling pathways.The immunofluorescence results indicated that quercetin,a significant active component in Fructus lycii,increased the mean staining area of 2-NBDG,TMRM,and MitoTracker,and decreased the area of CellRox compared to the control.Furthermore,the protein expression levels of p-38 MAPK,p-MAPK,p-JNK,p-PI3K,and p-AKT markedly increased after quercetin treatment.Conclusion Fructus lycii might alleviate exercise fatigue through multiple components and pathways.Among these,quercetin appears to improve exercise fatigue by enhancing energy metabolism and reducing oxidative stress.The PI3K-AKT and MAPK signaling pathways also appear to play a role in this process.

文摘Objective:To investigate the mechanism underlying the effects exerted by the Qizhu prescription(QZP)in breast cancer(BC),and the respective targets.Methods: Expression data from the ArrayExpress and The Cancer Genome Atlas(TCGA)were used to identify differentially expressed genes(DEGs)in BC.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed on the DEGs to identify genes involved in protein–protein interactions.Molecular docking was used to explore the dynamic relationship between active molecules and targets.Cell function experiments and animal studies were conducted to evaluate the effects of hub genes and active QZP compounds on BC cell behavior.Results: Among the 25 evaluated BC-related targets of QZP,matrix metalloproteinase-1(MMP1)and epidermal growth factor receptor(EGFR)exhibited the highest degrees of dysregulation.GO and KEGG enrichment analyses revealed that the anti-BC targets of QZP primarily affected drug responses and pathways in cancer cells.Molecular docking analysis suggested potential interactions between EGFR and quercetin/luteolin,as well as between MMP1 and luteolin/kaempferol/quercetin.Quercetin significantly reduced BC cell proliferation,migration,invasion,and tumor development in vivo.Treatment of BC cells with quercetin decreased the expression or activation of several associated proteins.Conclusion: The findings of our study provide new insights into the therapeutic potential of traditional Chinese medicine against BC,with particular reference to QZP.

文摘Plants of the genus Cordia(Boraginaceae family)are widely distributed in the tropical regions of America,Africa,and Asia.They are extensively used in folk medicine due to their rich medicinal properties.This review presents a comprehensive analysis of the isolation,structure,biogenesis,and biological properties of quinones from Cordia species reported from 1972 to 2023.Meroterpenoids were identified as the major quinones in most Cordia species and are reported as a chemotaxonomic markers of the Cordia.In addition to this property,quinones are reported to display a wider and broader spectrum of activities,are efficient scaffold in biological activity,compared to other classes of compounds reported in Cordia,hence our focus on the study of quinones reported from Cordia species.About 70 types of quinones have been isolated,while others have been identified by phytochemical screening or gas chromatography.Although the biosynthesis of quinones from Cordia species is not yet fully understood,previous reports suggest that they may be derived from geranyl pyrophosphate and an aromatic precursor unit,followed by oxidative cyclization of the allylic methyl group.Studies have demonstrated that quinones from this genus exhibit antifungal,larvicidal,antileishmanial,anti-inflammatory,antibiofilm,antimycobacterial,antioxidant,antimalarial,neuroinhibitory,and hemolytic activities.In addition,they have been shown to exhibit remarkable cytotoxic effects against several cancer cell lines which is likely related to their ability to inhibit electron transport as well as oxidative phosphorylation,and generate reactive oxygen species(ROS).Their biological activities indicate potential utility in the development of new drugs,especially as active components in drug-carrier systems,against a broad spectrum of pathogens and ailments.
文摘BACKGROUND Cellular senescence,a state of stable growth arrest,is intertwined with human cancers.However,characterization of cellular senescence-associated phenotypes in hepatocellular carcinoma(HCC)remains unexplored.AIM To address this issue,we delineated cellular senescence landscape across HCC.METHODS We enrolled two HCC datasets,TCGA-LIHC and International Cancer Genome Consortium(ICGC).Unsupervised clustering was executed to probe tumor heterogeneity based upon cellular senescence genes.Least absolute shrinkage and selection operator algorithm were utilized to define a cellular senescence-relevant scoring system.TRNP1 expression was measured in HCCs and normal tissues through immunohistochemistry,immunoblotting and quantitative real-time polymerase chain reaction.The influence of TMF-regulated nuclear protein(TRNP)1 on HCC senescence and growth was proven via a series of experiments.RESULTS TCGA-LIHC patients were classified as three cellular senescence subtypes,named C1–3.The robustness and reproducibility of these subtypes were proven in the ICGC cohort.C2 had the worst overall survival,C1 the next,and C3 the best.C2 presented the highest levels of immune checkpoints,abundance of immune cells,and immunogenetic indicators.Thus,C2 might possibly respond to immunotherapy.C2 had the lowest somatic mutation rate,while C1 presented the highest copy number variations.A cellular senescence-relevant gene signature was generated,which can predict patient survival,and chemo-or immunotherapeutic response.Experimentally,it was proven that TRNP1 presented the remarkable upregulation in HCCs.TRNP1 knockdown induced apoptosis and senescence of HCC cells and attenuated tumor growth.CONCLUSION These findings provide a systematic framework for assessing cellular senescence in HCC,which decode the tumor heterogeneity and tailor the pharmacological interventions to improve clinical management.
