The reduction of Cx43 has been known as a major inducer of arrhythmias after MIR, but the reason for the reduction of Cx43 remains largely unknown. The aim of this study was to find the key mechanism underlying the reduction of Cx43 after MIR and to screen out an herbal extract to attenuate arrhythmia after MIR. The differentially expressed genes in the peripheral blood mononuclear cell (PBMCs) after MIR were analyzed using the data from several gene expression omnibus data sets, followed by the identification in PBMCs and the serum of patients with myocardial infarction. Tumor necrosis factor superfamily protein 14 (TNFSF14) was increased in PBMCs and the serum of patients, which might be associated with the injury after MIR. The toxic effects of TNFSF14 on cardiomyocytes were investigated in vitro . Valtrate was screened out from several herbal extracts. Its protection against TNFSF14-induced injury was evaluated in cardiomyocytes and animal models with MIR. Recombinant TNFSF14 protein not only suppressed the viability of cardiomyocytes but also decreased Cx43 by stimulating the receptor LTβR. LTβR induces the competitive binding of MAX to MGA rather than the transcriptional factor c-Myc, thereby suppressing c-Myc-mediated transcription of Cx43. Valtrate promoted the N-linked glycosylation modification of LTβR, which reversed TNFSF14-induced reduction of Cx43 and attenuated arrhythmia after MIR. In all, valtrate suppresses TNFSF14-induced reduction of Cx43, thereby attenuating arrhythmia after MIR.</p>","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"418-433"},"PeriodicalIF":2.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141727295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This population-based, retrospective observational study extracted data from the US Nationwide Inpatient Sample between 2005 and 2018. Adults aged 20 years or older hospitalized for AMI were eligible for inclusion. Propensity score matching was applied to balance the characteristics between the comparison groups (ie, with and without Sjogren syndrome). Associations between Sjogren syndrome and in-hospital outcomes were determined using univariate and multivariable logistic regression analyses. A total of 1,735,142 patients were included. After propensity score matching, 4740 patients remained for subsequent analyses (948 had Sjogren syndrome and 3792 did not). After adjustment, patients with Sjogren syndrome had significantly lower in-hospital mortality (adjusted OR: 0.52, 95% CI, 0.36-0.73, P < 0.001), prolonged length of stay (aOR: 0.83, 95% CI, 0.69-0.995, P = 0.044), cardiogenic shock (aOR: 0.58, 95% CI, 0.40-0.83, P = 0.004), cardiac dysrhythmias (aOR: 0.77, 95% CI, 0.66-0.90, P < 0.001), acute kidney injury (aOR: 0.56, 95% CI, 0.45-0.70, P < 0.001), or respiratory failure (aOR: 0.63, 95% CI, 0.48-0.81, P < 0.001) than those without Sjogren syndrome. The stratified analysis revealed that Sjogren syndrome was associated with decreased odds of in-hospital mortality in patients with non-ST elevation myocardial infarction or ST-elevation myocardial infarction. In conclusion, among patients admitted to US hospitals for AMI, the patients with Sjogren syndrome have a lowered probability of in-hospital mortality, certain morbidities, and prolonged length of stay.

Phosphodiesterases (PDE) regulate cardiac electrical stability and may represent an interesting target. Recently, PDE8 inhibition was proposed as an antiarrhythmic intervention by increasing L-type Ca2+ current (ICa,L) and action potential duration (APD). However, the effect size of PDE8 inhibition on ICa,L and APD seems discrepant and effects on force are unknown. We investigated the impact of PDE8 inhibition on force using PF-04957325 in right atrial appendages, obtained from patients in sinus rhythm (SR) and with persistent AF (peAF) undergoing cardiac surgery. A computational model was employed to predict the effects of PDE8 inhibition on APD in SR and peAF. Results showed no increase in force after exposure to increasing concentrations of the PDE8 inhibitor PF-04957325 in either SR or peAF tissues. Furthermore, PDE8 inhibition did not affect the potency or efficacy of norepinephrine-induced inotropic effects in either group. Arrhythmic events triggered by norepinephrine were observed in both SR and peAF, but their frequency remained unaffected by PF-04957325 treatment. Computational modeling predicted that the reported increase in ICa,L induced by PDE8 inhibition would lead to substantial APD prolongation at all repolarization states, particularly in peAF. Our findings indicate that PDE8 inhibition does not significantly impact force or arrhythmogenicity in human atrial tissue.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":"42 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explored the interplay between IL-6, peroxisome proliferator-activated receptor gamma (PPARγ), and Lp(a) synthesis in HepG2 cells.

In in vitro experiments, IL-6-mediated LPA gene transcription was heightened with PPARγ knock-down and suppressed with pioglitazone, a PPARγ agonist.

Of note, two studies in single atrial hiPSC-CM reported prolongation of action potential duration by IKur block indicating that IKur might in fact represent a valuable target for the treatment of human AF. However, the results and interpretation are at odds with the literature on IKur block in human atria and the results of clinical studies. We believe that the discrepancies indicate that experiments in single atrial CM (both adult atrial CM and atrial hiPSC-CM) might be misleading. Under particular experimental conditions, atrial hiPSC-CMs may not closely resemble the electrophysiology of the human atrium.

Anthocyanins are water-soluble flavonoid pigments found in a wide array of common foods and fruits. Anthocyanins have the potential to contribute to the prevention and treatment of cardiovascular disease by improving lipid profiles and vascular function, reducing blood glucose levels and blood pressure, and inhibiting inflammation. These actions have been demonstrated in numerous clinical and preclinical studies. At the cellular and molecular level, anthocyanins and their metabolites could protect endothelial cells from senescence, apoptosis, and inflammation by activating the phosphoinositide 3-kinase/protein kinase B/endothelial nitric oxide synthases, silent information regulator 1 (SIRT1), or nuclear factor erythroid2-related factor 2 pathways and inhibiting the nuclear factor kappa B, Bax, or P38 mitogen-activated protein kinase pathways. Furthermore, anthocyanins prevent vascular smooth muscle cell from platelet-derived growth factor -induced or tumor necrosis factor-α-induced proliferation and migration by inhibiting the focal adhesion kinase and extracellular regulated protein kinases signaling pathways. Anthocyanins could also attenuate vascular inflammation by reducing the formation of oxidized lipids, preventing leukocyte adhesion and infiltration of the vessel wall, and macrophage phagocytosis of deposited lipids through reducing the expression of cluster of differentiation 36 and increasing the expression of ATP-binding cassette subfamily A member 1 and ATP-binding cassette subfamily G member 1. At the same time, anthocyanins could lower the risk of thrombosis by inhibiting platelet activation and aggregation through down-regulating P-selectin, transforming growth factor-1, and CD40L.
