Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression by binding to target messenger RNAs (mRNAs). miRNAs have been implicated in a variety of cardiovascular and neurological diseases, such as myocardial infarction, cardiomyopathies of various geneses, rhythmological diseases, neurodegenerative illnesses and strokes. Numerous studies have focused on the expression of miRNA patterns with respect to atrial fibrillation (AF) or acute ischemic stroke (AIS) However, only a few studies have addressed the expression pattern of miRNAs in patients with AF and AIS in order to provide not only preventive information but also to identify therapeutic potentials. Therefore, the aim of this review is to summarize 18 existing manuscripts that have dealt with this combined topic of AF and associated AIS in detail and to shed light on the most frequently mentioned miRNAs-1, -19, -21, -145 and -146 with regard to their molecular mechanisms and targets on both the heart and the brain. From this, possible diagnostic and therapeutic consequences for the future could be derived.

Abstract
Atrial fibrillation (AFib), the most prevalent arrhythmia in clinical practice, presents a growing global health concern, particularly with the aging population, as it is associated with devastating complications and an impaired quality of life. Its pathophysiology is multifactorial, including the pathways of fibrosis, inflammation, and oxidative stress. MicroRNAs (miRNAs), small non-coding RNA molecules, have emerged as substantial contributors in AFib pathophysiology, by affecting those pathways. In this review, we explore the intricate relationship between miRNAs and the aforementioned aspects of AFib, shedding light on the molecular pathways as well as the potential diagnostic applications. Recent evidence also suggests a possible role of miRNA therapeutics in maintenance of sinus rhythm via the antagonism of miR-1 and miR-328, or the pharmacological upregulation of miR-27b and miR-223-3p. Unraveling the crosstalk between specific miRNA profiles and genetic predispositions may pave the way for personalized therapeutic approaches, setting the tone for precision medicine in atrial fibrillation.

M2 macrophage‑derived exosomes alleviate KCa3.1 channel expression in rapidly paced HL‑1 myocytes via the NF‑κB (p65)/STAT3 signaling pathway. Mol Med Rep 2024; 29:55. [PMID: 38334149 PMCID: PMC10877089 DOI: 10.3892/mmr.2024.13179] [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: 09/08/2023] [Accepted: 01/25/2024] [Indexed: 02/10/2024] Open
Abstract
The present study was designed to explore the role of M2 macrophage‑derived exosomes (M2‑exos) on the KCa3.1 channel in a cellular atrial fibrillation (AF) model using rapidly paced HL‑1 myocytes. M2 macrophages and M2‑exos were isolated and identified. MicroRNA (miR)‑146a‑5p levels in M2 macrophages and M2‑exos were quantified using reverse transcription‑quantitative PCR (RT‑qPCR). HL‑1 myocytes were randomly divided into six groups: Control group, pacing group, pacing + coculture group (pacing HL‑1 cells cocultured with M2‑exos), pacing + mimic‑miR‑146a‑5p group, pacing + NC‑miR‑146a‑5p group and pacing + pyrrolidine dithiocarbamate (PDTC; a special blocker of the NF‑κB signaling pathway) group. Transmission electron microscopy, nanoparticle tracking analysis, western blotting, RT‑qPCR and immunohistochemistry were performed in the present study. A whole‑cell clamp was also applied to record the current density of KCa3.1 and action potential duration (APD) in each group. The results revealed that miR‑146a‑5p was highly expressed in both M2 macrophages and M2‑exos. Pacing HL‑1 cells led to a shorter APD, an increased KCa3.1 current density and higher protein levels of KCa3.1, phosphorylated (p‑)NF‑κB p65, p‑STAT3 and IL‑1β compared with the control group. M2‑exos, miR‑146a‑5p‑mimic and PDTC both reduced the protein expression of KCa3.1, p‑NF‑κB p65, p‑STAT3 and IL‑1β and the current density of KCa3.1, resulting in a longer APD in the pacing HL‑1 cells. In conclusion, M2‑exos and their cargo, which comprised miR‑146a‑5p, decreased KCa3.1 expression and IL‑1β secretion in pacing HL‑1 cells via the NF‑κB/STAT3 signaling pathway, limiting the shorter APD caused by rapid pacing.

[PMID: 38152023 DOI: 10.1113/jp283960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 12/05/2023] [Indexed: 12/29/2023] Open
Abstract
It has been documented that increased sympathetic activity contributes to the development of cardiovascular diseases, such as hypertension. We previously reported that β-arrestin-1, a multifunctional cytoskeletal protein, was downregulated in the rostral ventrolateral medulla (RVLM) of the spontaneously hypertensive rat (SHR), and its overexpression elicited an inhibitory effect on sympathetic activity in hypertension. microRNA (miR)-22-3p has been reported to be associated with the pathological progress of hypertension. The purpose of this study was to determine the role of miR-22-3p in β-arrestin-1-mediated central cardiovascular regulation in hypertension. It was observed that miR-22-3p was upregulated in the RVLM of SHRs compared with normotensive Wistar-Kyoto (WKY) rats, and it was subsequently confirmed to target the β-arrestin-1 gene using a dual-luciferase reporter assay. miR-22-3p was downregulated in the RVLM using adeno-associated virus with 'tough decoys', which caused a significant increase of β-arrestin-1 expression and decrease of noradrenaline and blood pressure (BP) in SHRs. However, upregulation of miR-22-3p using lentivirus in the RVLM of WKY rats significantly increased BP. In in vitro PC12 cells, enhanced oxidative stress activity induced by angiotensin II was counteracted by pretreatment with miR-22-3p inhibitor, and this effect could be abolished by β-arrestin-1 gene knockdown. Furthermore, microglia exhaustion significantly diminished miR-22-3p expression, and enhanced β-arrestin-1 expression in the RVLM of SHRs. Activation of BV2 cells in vitro evoked a significant increase of miR-22-3p expression, and this BV2 cell culture medium was also able to facilitate miR-22-3p expression in PC12 cells. Collectively, our findings support a critical role for microglia-derived miR-22-3p in inhibiting β-arrestin-1 in the RVLM, which is involved in central cardiovascular regulation in hypertension. KEY POINTS: Impairment of β-arrestin-1 function in the rostral ventrolateral medulla (RVLM) has been reported to be associated with the development of sympathetic overactivity in hypertension. However, little is known about the potential mechanisms of β-arrestin-1 dysfunction in hypertension. miR-22-3p is implicated in multiple biological processes, but the role of miR-22-3p in central regulation of cardiovascular activity in hypertension remains unknown. We predicted that miR-22-3p could directly bind to the β-arrestin-1 gene (Arrb1), and this hypothesis was confirmed by using a dual-luciferase reporter assay. Inhibition of β-arrestin-1 by miR-22-3p was further verified in both in vivo and in vitro experiments. Furthermore, our results suggested miR-22-3p as a risk factor for oxidative stress in the RVLM, thus contributing to sympatho-excitation and hypertension. Our present study provides evidence that microglia-derived miR-22-3p may underlie the pathogenesis and progression of neuronal hypertension by inhibiting β-arrestin-1 in the RVLM.

Abstract
MicroRNAs (miRNAs; miRs) are small non-coding ribonucleic acids sequences vital in regulating gene expression. They are significant in many biological and pathological processes and are even detectable in various body fluids such as serum, plasma, and urine. Research has demonstrated that the irregularity of miRNA in multiplying cardiac cells is linked to developmental deformities in the heart's structure. It has also shown that miRNAs are crucial in diagnosing and progressing several cardiovascular diseases (CVDs). The review covers the function of miRNAs in the pathophysiology of CVD. Additionally, the review provides an overview of the potential role of miRNAs as disease-specific diagnostic and prognostic biomarkers for human CVD, as well as their biological implications in CVD.

Abstract
BACKGROUND As the most common arrhythmia, atrial fibrillation (AF) is associated with a significantly increased risk of stroke, which causes high disability and mortality. To date, the underlying mechanism of stroke occurring after AF remains unclear. Herein, we studied hub genes and regulatory pathways involved in AF and secondary stroke and aimed to reveal biomarkers and therapeutic targets of AF-related stroke. METHODS The GSE79768 and GSE58294 datasets were used to analyze AF- and stroke-related differentially expressed genes (DEGs) to obtain a DEG1 dataset. Weighted correlation network analysis (WGCNA) was used to identify modules associated with AF-related stroke in GSE66724 (DEG2). DEG1 and DEG2 were merged, and hub genes were identified based on protein-protein interaction networks. Gene Ontology terms were used to analyze the enriched pathways. The GSE129409 and GSE70887 were applied to construct a circRNA-miRNA-mRNA network in AF-related stroke. Hub genes were verified in patients using quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS We identified 3,132 DEGs in blood samples and 253 DEGs in left atrial specimens. Co-expressed hub genes of EIF4E3, ZNF595, ZNF700, MATR3, ACKR4, ANXA3, SEPSECS-AS1, and RNF166 were significantly associated with AF-related stroke. The hsa_circ_0018657/hsa-miR-198/EIF4E3 pathway was explored as the regulating axis in AF-related stroke. The qRT-PCR results were consistent with the bioinformatic analysis. CONCLUSIONS Hub genes EIF4E3, ZNF595, ZNF700, MATR3, ACKR4, ANXA3, SEPSECS-AS1, and RNF166 have potential as novel biomarkers and therapeutic targets in AF-related stroke. The hsa_circ_0018657/hsa-miR-198/EIF4E3 axis could play an important role regulating the development of AF-related stroke.

Abstract
Atrial fibrillation is a complex and multifactorial disease. Although prophylactic anticoagulation has great benefits in avoiding comorbidities, adverse cardiovascular events still occur and thus in recent decades, many resources have been invested in the identification of useful markers in the prevention of the risk of MACE in these patients. As such, microRNAs, that are small non-coding RNAs whose function is to regulate gene expression post-transcriptionally, have a relevant role in the development of MACE. miRNAs, have been investigated for many years as potential non-invasive biomarkers of several diseases. Different studies have shown their utility in the diagnosis and prognosis of cardiovascular diseases. In particular, some studies have associated the presence of certain miRNAs in plasma with the development of MACE in AF. Despite these results, there are still many efforts to be done to allow the clinical use of miRNAs. The lack of standardization concerning the methodology in purifying and detecting miRNAs, still provides contradictory results. miRNAs also have a functional impact in MACE in AF through the dysregulation of immunothrombosis. Indeed, miRNAs may be a link between MACE and inflammation, through the regulation of neutrophil extracellular traps that are a key element in the establishment and evolution of thrombotic events. The use of miRNAs as therapy against thromboinflammatory processes should also be a future approach to avoid the occurrence of MACE in atrial fibrillation.

Impaired regulation of MMP2/16-MLCK3 by miR-146a-5p increased susceptibility to myocardial ischemic injury in aging mice. Cardiovasc Res 2022; 119:786-801.

Abstract
AIMS Aging impairs cardiac function and increases susceptibility to myocardial ischemic injury. Cardiac myosin light chain kinase (MLCK3) phosphorylates cardiac myosin regulatory light chain (MLC2), controlling sarcomere organization and cardiomyocyte contraction. Dysregulation of MLCK3 and phosphorylated MLC2 (p-MLC2) contributes to heart failure after myocardial infarction (MI). We aimed at exploring how the MLCK3-p-MLC2 axis changes in aging hearts post MI and at investigating the underlying regulatory mechanisms. METHODS AND RESULTS We generated adult (3 months) and aged (30 months) MI mouse models to compare their cardiac performance, and then detected MLCK3 expression and MLC2 activity. Aging increased the size of MI-induced infarctions and promoted cardiac contractile dysfunction. Furthermore, MLCK3 expression and MLC2 activity increased in adult hearts after MI, but not in aged hearts. miR-146a was found consistently increased in adult and aged hearts post-MI. Mechanistic analyses performed in vitro demonstrated that miR-146a-5p downregulated matrix metalloprotease (MMP)2/16 expression in cardiomyocytes. This downregulation in turn increased MLCK3 expression and MLC2 activity. However, miR-146a-5p failed to regulate the MMP2/16-MLCK3-p-MLC2 axis in senescent cardiomyocytes or in cardiac miR-146a conditional knockout mice, with the latter experiencing an exacerbated deterioration of cardiac function post-MI. CONCLUSION These results suggest that increase of MLCK3 and p-MLC2 contents through decreasing MMP2/16 by miR-146a-5p represents a compensatory mechanism that can protect cardiac contractile function after MI. Aging impairs this miR-146a-5p-regulated MMP2/16-MLCK3-p-MLC2 contractile axis, leading to compromised contractile function and increased susceptibility to heart failure.

Abstract
Abstract
Background: To study the correlations of serum galectin-3 (Gal-3) and soluble growth stimulating expressed gene 2 (sST2) levels with prognosis of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).
Methods: A total of 112 patients diagnosed from August 2015 to October 2017 were selected. They were followed up for 3 years. Based on major adverse cardiovascular events (MACEs) during follow-up, they were divided into MACE and non-MACE groups. Multivariate logistic regression analysis was performed to explore the independent risk factors for MACEs. A nomogram model was established using the factors and validated. The optimal cut-off values of Gal-3 and sST2 levels were determined by receiver operating characteristic curves. Kaplan-Meier method was used for survival analysis.
Results: MACEs occurred in 78 patients during follow-up. Patients in the MACE group were more often hypertensive, had higher total cholesterol, uric acid, sST2 and Gal-3, and lower left ventricular ejection fraction (LVEF) (P<0.05). CK-MB, sST2, Gal-3 and LVEF were the independent risk factors for MACEs (P<0.05). The nomogram model established with these factors had high accuracy for predicting overall survival, and its concordance index (C-index) was 0.768 (95% confidence interval: 0.692-0.865). The prognosis of the patients with Gal-3 ≥12.57 μg/ mL and sST2 ≥18.56 ng/mL was poorer 3 years after PCI.
Conclusions: The levels of serum Gal-3 and sST2 are the independent risk factors for MACEs in AMI patients following PCI, with high prognostic value.

Role of Cardiomyocyte-Derived Exosomal MicroRNA-146a-5p in Macrophage Polarization and Activation. DISEASE MARKERS 2022; 2022:2948578. [PMID: 35548775 PMCID: PMC9085364 DOI: 10.1155/2022/2948578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 01/25/2022] [Accepted: 04/06/2022] [Indexed: 11/18/2022]
Abstract
Myocardial infarction arises from an excessive or prolonged inflammatory response, leading to ventricular remodeling or impaired cardiac function. Macrophages exhibit different polarization types associated with inflammation both at steady state and after myocardial infarction. Exosomal miR-146a-5p has been identified as an important molecule in the cardiovascular field in recent years. However, the effect of cardiomyocyte-derived exosomal miR-146a-5p on macrophages has not yet been elucidated. Initially, we found that exosomes with low expression of miR-146a-5p derived from myocardial infarction tissues modulated macrophage polarization. To determine whether cardiomyocyte-derived exosomal miR-146a-5p mediated macrophage polarization, we treated macrophages with exosomes rich in miR-146a-5p collected from neonatal mouse cardiomyocytes. The effects of exosomal miR-146a-5p on macrophage polarization were measured using RT-qPCR, transwell assays, and western blotting. The results showed that the increased expression of miR-146a-5p promoted M1 macrophage polarization, inhibited M2 macrophage polarization, and increased the expression of VEGFA. However, the decreased expression of exosomalmiR-146a-5p showed the opposite trends. Interestingly, in contrast to treatment with the solitary miR-146a-5p mimic, exosomal miR-146a-5p derived from neonatal mouse cardiomyocytes reduced TNFα and iNOS expression. In addition, when macrophages were activated by the miR-146a-5p mimic or exosomal miR-146a-5p, the expression of TNF receptor-associated factor 6 (TRAF6), a target gene of miR-146a-5p, was reduced significantly. Taken together, these findings indicate that exosomal miR-146a-5p derived from cardiomyocytes could stimulate M1 macrophage polarization to induce an inflammatory reaction, while targeting TRAF6, exerting an anti-inflammatory effect. Exosomal miR-146a-5p plays important roles in macrophages, illuminating a novel potential therapeutic target in myocardial infarction.

[PMID: 35307895 DOI: 10.1002/jbt.23034] [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: 05/31/2021] [Revised: 01/08/2022] [Accepted: 03/02/2022] [Indexed: 11/08/2022]
Abstract
Catalpol (CA) is widely used in the protection of cardiomyocytes. Nevertheless, the mechanism of CA in alleviating ischemia-reperfusion-induced injury of cardiomyocytes remains unclear. Human cardiomyocyte AC16 cells were subjected to hypoxia/reoxygenation (H/R) injury. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot analysis were applied to detect tumor necrosis factor-alpha (TNF-α) mRNA, interleukin-6 (IL-6) mRNA, interleukin-1beta (IL-1β) mRNA, microRNA-22-3p (miR-22-3p), dipeptidyl peptidase 4 (DPP4) mRNA, and DPP4 protein expressions. The cell viability and apoptosis were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry, respectively. Lactate dehydrogenase (LDH) and creatine kinase (CK-MB) were examined by enzyme-linked immunosorbent assay (ELISA) kits. A dual-luciferase reporter gene assay was performed to confirm the binding sequence between miR-22-3p and DPP4 mRNA 3'-untranslated region (3'UTR). CA promoted the viability and reduced cell apoptosis of AC16 cells and repressed the release of inflammatory cytokines TNF-α, IL-6, and IL-1β, and inhibited the leakage of myocardial injury markers LDH and CK-MB. Furthermore, CA enhanced the expression of miR-22-3p in cardiomyocytes, and DPP4 was validated to be the target gene of miR-22-3p. The inhibition of miR-22-3p and augmentation of DPP4 reversed the above effects of CA. CA protects A16 cells from H/R injury by regulating the miR-22-3p/DPP4 axis.

MiR-32-3p Regulates Myocardial Injury Induced by Microembolism and Microvascular Obstruction by Targeting RNF13 to Regulate the Stability of Atherosclerotic Plaques. J Cardiovasc Transl Res 2021; 15:143-166. [PMID: 34185281 DOI: 10.1007/s12265-021-10150-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 06/16/2021] [Indexed: 10/21/2022]
Abstract
This study aimed to explore the molecular mechanism of myocardial protection. The effects of miR-32-3p and ring finger protein 13 (RNF13) on endoplasmic reticulum (ER) stress-induced apoptosis of A-10 cells and human umbilical vein endothelial cells (HUVEC) were detected using flow cytometry. The effects of miR-32-3p and phenylbutyric acid (PBA) on plaque instability and myocardial tissue injury in rats were investigated after establishment of arterial plaque model and embolization model and treatment with miR-32-3p-antagomir and PBA. RNF13, which was differentially expressed in myocardial infarction, was the direct target gene of miR-32-3p. MiR-32-3p inhibited RNF13 expression and targeted RNF13 to inhibit ER stress-induced cell apoptosis. Furthermore, inhibiting miR-32-3p expression induced arterial plaque instability by reducing survival, increasing pathological lesions in arterial tissue, up-regulating ER stress-related proteins, and regulating the expressions of apoptosis-related proteins in the model rats. However, PBA reversed the effects of miR-32-3p-antagomir on the model rats. MiR-32-3p regulates myocardial injury induced by micro-embolism and micro-vascular obstruction by targeting RNF13 to regulate the stability of atherosclerotic plaques.

Abstract
Global epidemiological studies show that chronic non-communicable diseases such as atherosclerosis and metabolic disorders represent the leading cause of premature mortality and morbidity. Cardiovascular disease such as ischemic heart disease is a major contributor to the global burden of disease and the socioeconomic health costs. Clinical and epidemiological data show an association of typical oxidative stress markers such as lipid peroxidation products, 3-nitrotyrosine or oxidized DNA/RNA bases with all major cardiovascular diseases. This supports the concept that the formation of reactive oxygen and nitrogen species by various sources (NADPH oxidases, xanthine oxidase and mitochondrial respiratory chain) represents a hallmark of the leading cardiovascular comorbidities such as hyperlipidemia, hypertension and diabetes. These reactive oxygen and nitrogen species can lead to oxidative damage but also adverse redox signaling at the level of kinases, calcium handling, inflammation, epigenetic control, circadian clock and proteasomal system. The in vivo footprints of these adverse processes (redox biomarkers) are discussed in the present review with focus on their clinical relevance, whereas the details of their mechanisms of formation and technical aspects of their detection are only briefly mentioned. The major categories of redox biomarkers are summarized and explained on the basis of suitable examples. Also the potential prognostic value of redox biomarkers is critically discussed to understand what kind of information they can provide but also what they cannot achieve.
