Abstract
ABSTRACT Background: One of the mechanisms responsible for the high mortality rate of acute myocardial infarction is myocardial ischemia-reperfusion injury (MI-RI). The present study focused on the role and regulatory mechanisms of specificity protein 1 (SP1) and ubiquitin-specific protease 46 (USP46) in oxygen-glucose deprivation/reperfusion (OGD/R)-induced cardiomyocyte injury. Methods: OGD/R was used to treat cardiomyocytes AC16 to mimic ischemia-reperfusion in vitro . Cell viability, proliferation, and apoptosis were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, 5-ethynyl-2'-deoxyuridine, and flow cytometry assays. Enzyme-linked immunosorbent assays analyzed the concentrations of TNF-α and IL-1β. Several protein levels were analyzed by western blotting. The levels of iron (Fe 2+ ), reactive oxygen species, malondialdehyde, and the activities of superoxide dismutase were analyzed by commercial kits. Chromatin immunoprecipitation and dual-luciferase report assays assessed the relationship between USP46 and SP1. Results: USP46 and SP1 were upregulated in serum from MI patients and they had a positive correlation. OGD/R stimulation suppressed cardiomyocyte viability and proliferation, as well as induced cardiomyocyte inflammation, oxidative stress (OxS) injury, apoptosis, and ferroptosis, but these effects were impaired by USP46 or SP1 knockdown. SP1 could enhance the transcription of USP46, and USP46 overexpression reversed SP1 silencing-mediated effects on OGD/R-induced cardiomyocytes. SP1 mediated the AMPK signaling via USP46 . Conclusion: SP1 mediated OGD/R-induced cardiomyocyte inflammation, OxS injury, apoptosis, and ferroptosis by inactivating the AMPK signaling via enhancing the transcription of USP46.

Sütő B, Kun J, Bagoly T, Németh T, Pintér E, Kardos D, Helyes Z. Plasma Somatostatin Levels Are Lower in Patients with Coronary Stenosis and Significantly Increase after Stent Implantation. J Clin Med 2024; 13:4727. [PMID: 39200869 PMCID: PMC11355572 DOI: 10.3390/jcm13164727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Revised: 07/22/2024] [Accepted: 08/08/2024] [Indexed: 09/02/2024] Open
Abstract
Background/Objectives: Stimulated capsaicin-sensitive peptidergic sensory nerves release somatostatin (SST), which has systemic anti-inflammatory and analgesic effects, correlating with the severity of tissue injury. Previous studies suggest that SST release into the systemic circulation is likely to serve as a protective mechanism during thoracic and orthopedic surgeries, scoliosis operations, and septic conditions, all involving significant tissue damage, pain, and inflammation. In a severe systemic inflammation rat model, SST released from sensory nerves into the bloodstream enhanced innate defense, reducing mortality. Inflammation is the key pathophysiological process responsible for the formation, progression, instability, and healing of atherosclerotic plaques. Methods: We measured SST-like immunoreactivity (SST-LI) in the plasma of healthy volunteers in different age groups and also that of stable angina patients with coronary heart disease (CHD) using ELISA and tracked changes during invasive coronary interventions (coronarography) with and without stent implantation. Samples were collected at (1) pre-intervention, (2) after coronarography, (3) 2 h after coronarography initiation and coronary stent placement, and (4) the next morning. Results: There was a strong negative correlation between SST-LI concentrations and age; the plasma SST-LI of older healthy volunteers (47-73 years) was significantly lower than in young ones (24-27 years). Baseline SST-LI in CHD patients who needed stents was significantly reduced compared to those not requiring stents. Plasma SST-LI significantly increased two hours post stent insertion and the next morning compared to pre-intervention levels. Conclusions: Age-related SST decrease might be a consequence of lower gene expression within specific hypo-thalamic nuclei as has been previously demonstrated in rodent animals. Reperfusion of ischemic myocardium post-stent implantation may trigger SST release, potentially offering protective benefits in coronary heart disease. Investigating this SST-mediated mechanism could offer valuable insights for future therapies.

Abstract
Myocardial ischemia-reperfusion (MI/R) injury is a common and serious complication following reperfusion treatment for myocardial infarction (MI). Increasing evidence has verified the crucial role of circular RNAs (circRNAs) in the MI/R injury processes. The objective of this study was to investigate the effects and potential regulatory mechanisms of circHMGA2 on MI/R injury. Hypoxia/reoxygenation (H/R) models were established using human cardiac myocytes (HCMs) and mice models were induced by MI/R. The level of circHMGA2 was detected by RT-qPCR. Myocardial function was evaluated by the hemodynamic parameters, the activity of serum myocardial enzymes, HE staining and TUNEL assays. Cell proliferation was measured by CCK-8 assay. The ferrous ion (Fe2+) level was determined with an iron assay kit. Ferroptosis- and pyroptosis-related proteins were determined using western blotting. The levels of oxidative stress and inflammatory factors were analyzed using DCFH-DA staining or ELISA assays. CircHMGA2 was upregulated in H/R-induced HCMs and myocardial tissues of MI/R mice. In vitro, circHMGA2 knockdown attenuated the proliferation inhibition, restrained the ferroptosis and pyroptosis in H/R-induced HCMs. This regulatory mechanism may be associated with the suppression of NLRP3 pathway. In vivo, circHMGA2 depletion attenuated myocardial tissue damage of MI/R mice through inhibiting the oxidative stress and pyroptosis. Taken together, CircHMGA2 enhanced MI/R injury via promoting ferroptosis and pyroptosis, providing new insights into the treatment of MI/R injury.

Abstract
The meticulous control of cardiac sympathetic and parasympathetic tone regulates all facets of cardiac function. This precise calibration of cardiac efferent innervation is dependent on sensory information that is relayed from the heart to the central nervous system. The vagus nerve, which contains vagal cardiac afferent fibers, carries sensory information to the brainstem. Vagal afferent signaling has been predominantly shown to increase parasympathetic efferent response and vagal tone. However, cardiac vagal afferent signaling appears to change after cardiac injury, though much remains unknown. Even though subsequent cardiac autonomic imbalance is characterized by sympathoexcitation and parasympathetic dysfunction, it remains unclear if, and to what extent, vagal afferent dysfunction is involved in the development of vagal withdrawal. This review aims to summarize the current understanding of cardiac vagal afferent signaling under in health and in the setting of cardiovascular disease, especially after myocardial infarction, and to highlight the knowledge gaps that remain to be addressed.

Abstract
Pain is one of the most serious problems plaguing human health today. Pain is not an independent pathophysiological condition and is associated with a high impact on elevated disability and organ dysfunction. Several lines of evidence suggested the associations of pain with cardiovascular diseases, especially myocardial ischemia-reperfusion (I/R) injury, while the role of pain in I/R injury and related mechanisms are not yet comprehensively assessed. In this review, we attempted to explore the role of pain in myocardial I/R injury, and we concluded that acute pain protects myocardial ischemia-reperfusion injury and chronic pain aggravates cardiac ischemia-reperfusion injury. In addition, the construction of different pain models and animal models commonly used to study the role of pain in myocardial I/R injury were discussed in detail, and the potential mechanism of pain-related myocardial I/R injury was summarized. Finally, the future research direction was prospected. That is, the remote regulation of pain to cardiac function requires peripheral pain signals to be transmitted from the peripheral to the cardiac autonomic nervous system, which then affects autonomic innervation during cardiac ischemia-reperfusion injury and finally affects the cardiac function.

Abstract
Familial dysautonomia (FD) is a currently untreatable, neurodegenerative disease caused by a splicing mutation (c.2204+6T>C) that causes skipping of exon 20 of the elongator complex protein 1 (ELP1) pre-mRNA. Here, we used adeno-associated virus serotype 9 (AAV9-U1-FD) to deliver an exon-specific U1 (ExSpeU1) small nuclear RNA, designed to cause inclusion of ELP1 exon 20 only in those cells expressing the target pre-mRNA, in a phenotypic mouse model of FD. Postnatal systemic and intracerebral ventricular treatment in these mice increased the inclusion of ELP1 exon 20. This also augmented the production of functional protein in several tissues including brain, dorsal root, and trigeminal ganglia. Crucially, the treatment rescued most of the FD mouse mortality before one month of age (89% vs 52%). There were notable improvements in ataxic gait as well as renal (serum creatinine) and cardiac (ejection fraction) functions. RNA-seq analyses of dorsal root ganglia from treated mice and human cells overexpressing FD-ExSpeU1 revealed only minimal global changes in gene expression and splicing. Overall then, our data prove that AAV9-U1-FD is highly specific and will likely be a safe and effective therapeutic strategy for this debilitating disease.

Abstract
Little is known about the role of the neuropeptide somatostatin (SST) in myocardial ischemia/reperfusion injury and cardioprotection. Here, we investigated the direct cardiocytoprotective effect of SST on ischemia/reperfusion injury in cardiomyocyte cultures, as well as the expression of SST and its receptors in pig and human heart tissues. SST induced a bell-shaped, concentration-dependent cardiocytoprotection in both adult rat primary cardiomyocytes and H9C2 cells subjected to simulated ischemia/reperfusion injury. Furthermore, in a translational porcine closed-chest acute myocardial infarction model, ischemic preconditioning increased plasma SST-like immunoreactivity. Interestingly, SST expression was detectable at the protein, but not at the mRNA level in the pig left ventricles. SSTR1 and SSTR2, but not the other SST receptors, were detectable at the mRNA level by PCR and sequencing in the pig left ventricle. Moreover, remote ischemic conditioning upregulated SSTR1 mRNA. Similarly, SST expression was also detectable in healthy human interventricular septum samples at the protein level. Furthermore, SST-like immunoreactivity decreased in interventricular septum samples of patients with ischemic cardiomyopathy. SSTR1, SSTR2, and SSTR5 but not SST and the other SST receptors were detectable at the mRNA level by sequencing in healthy human left ventricles. In addition, in healthy human left ventricle samples, SSTR1 and SSTR2 mRNAs were expressed especially in vascular endothelial and some other cell types as detected by RNA Scope® in situ hybridization. This is the first demonstration that SST exerts a direct cardiocytoprotective effect against simulated ischemia/reperfusion injury. Moreover, SST is expressed in the heart tissue at the peptide level; however, it is likely to be of sensory neural origin since its mRNA is not detectable. SSTR1 and SSTR2 might be involved in the cardioprotective action of SST, but other mechanisms cannot be excluded.

Abstract
Endothelial barrier integrity is important for vascular homeostasis, and hyperpermeability participates in the progression of many pathological states, such as diabetic retinopathy, ischemic stroke, chronic bowel disease, and inflammatory disease. Here, using drug repositioning, we discovered that primaquine diphosphate (PD), previously known as an antimalarial drug, was a potential blocker of vascular leakage. PD inhibited the linear pattern of vascular endothelial growth factors (VEGF)-induced disruption at the cell boundaries, blocked the formation of VEGF-induced actin stress fibers, and stabilized the cortactin actin rings in endothelial cells. PD significantly reduced leakage in the Miles assay and mouse model of streptozotocin (STZ)-induced diabetic retinopathy. Targeted prediction programs and deubiquitinating enzyme activity assays identified a potential mechanism of action for PD and demonstrated that this operates via ubiquitin specific protease 1 (USP1). USP1 inhibition demonstrated a conserved barrier function by inhibiting VEGF-induced leakage in endothelial permeability assays. Taken together, these findings suggest that PD could be used as a novel drug for vascular leakage by maintaining endothelial integrity.

Abstract
BACKGROUND The oxidative stress is regarded as one of the main contributors to the health problem. Cyclooxygenase-2 (COX-2) and matrix metallopeptidase-9 (MMP-9) are two of the important genes that are reported to be involved in the cardiovascular disease (CVD) development in the molecular and genetic association studies. The aim of this study was to evaluate the level of expression of COX-2 and MMP-9 after selenium supplementation in patients with coronary artery disease (CAD). METHODS In this sub-study of Selenegene study, subjects were randomly divided into groups, 19 subjects who received selenium and 22 patients with CAD who received placebo. Patients received either 200-mg selenium yeast tablets or placebo tablets after a meal, once daily for 60 days. The messenger ribonucleic acid (mRNA) levels of the selenium and prostaglandin-endoperoxide synthase 2 (PTGS2) (COX-2) and MMP-9 genes products were determined before and after the study. RESULTS In this sub-study, 41 Iranian patients with CVD were enrolled (placebo group: n = 22, selenium intervention: n = 19). Fasting blood sugar (FBS) was higher among placebo group than selenium group (93.4 ± 12.7 vs. 124.4 ± 40.6 mg/dl, P = 0.03). Triglyceride (TG) level was higher among selenium group versus placebo group (123.3 ± 34.0 vs. 184.8 ± 69.4 mg/dl, P = 0.006). The data analysis demonstrated that the expression of MMP-9 and COX-2 genes did not change significantly in both selenium and placebo groups. CONCLUSION This study showed a positive association between the expression of MMP-9 and COX-2 in the patients with CAD who received selenium but not the placebo groups. Yet, these findings need to be confirmed in further details and expanded sample size.

Abstract
During the last decades, mortality from acute myocardial infarction has been dramatically reduced. However, the incidence of post-infarction heart failure is still increasing. Cardioprotection by ischaemic conditioning had been discovered more than three decades ago. Its clinical translation, however, is still an unmet need. This is mainly due to the disrupted cardioprotective signalling pathways in the presence of different cardiovascular risk factors, co-morbidities and the medication being taken. Sensory neuropathy is one of the co-morbidities that has been shown to interfere with cardioprotection. In the present review, we summarize the diverse aetiology of sensory neuropathies and the mechanisms by which these neuropathies may interfere with ischaemic heart disease and cardioprotective signalling.

Liu X, Yuan X, Liang G, Zhang S, Zhang G, Qin Y, Zhu Q, Xiao Q, Hou N, Luo JD. BRG1 protects the heart from acute myocardial infarction by reducing oxidative damage through the activation of the NRF2/HO1 signaling pathway. Free Radic Biol Med 2020; 160:820-836. [PMID: 32950688 DOI: 10.1016/j.freeradbiomed.2020.09.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 07/21/2020] [Accepted: 09/10/2020] [Indexed: 12/12/2022]
Abstract
Brahma-related gene 1 (BRG1) regulates the chromatin structure and expression of cardiac genes. Although BRG1 is downregulated in adult cardiomyocytes, it is reactivated during cardiac stress. The role of BRG1 in acute myocardial infarction (AMI) has not been clearly defined. This study assessed the protective role of BRG1 in AMI using cell cultures and an animal model and explored the underlying molecular events. The results showed that in the peri-infarct zone, expression of BRG1 protein was significantly increased relative to the sham group, which was accompanied by NRF2 and HO1 upregulation and KEAP1 downregulation. BRG1 overexpression through adenoviral intramyocardial injection into AMI mice reduced the infarct size and improved cardiac functions with upregulation of NRF2 and its target HO1 and attenuated oxidative damage and cell apoptosis. However, shRNA-mediated Brg1 knockdown had the opposite effects. These results were further confirmed in cultured primary neonatal rat cardiomyocytes (NRCMs) with oxygen-glucose deprivation (OGD). Moreover, the selective NRF2 inhibitor brusatol could partially reverse cardiomyocyte antioxidant ability and BRG1 overexpression-induced cardiac protection in vitro. In addition, co-immunoprecipitation and immunofluorescence data showed that BRG1 overexpression significantly promoted the BRG1/NRF2 co-localization in cardiomyocytes. The chromatin immunoprecipitation-qPCR revealed BRG1 interaction with the Ho1 promoter and BRG1 overexpression could induce BRG1 binding to the Ho1 promoter during the OGD. In conclusion, this study demonstrated that BRG1 upregulation during AMI in vitro and in vivo increased the NRF2 level and NRF2 nuclear accumulation for HO1 expression to alleviate cardiac myocyte oxidative stress and upregulate cardiomyocyte viability. The BRG1-NRF2-HO1 pathway may represent a novel therapeutic target in the prevention of cardiac dysfunction in AMI patients.

Capsaicin-Sensitive Sensory Nerves and the TRPV1 Ion Channel in Cardiac Physiology and Pathologies. Int J Mol Sci 2020; 21:ijms21124472. [PMID: 32586044 PMCID: PMC7352834 DOI: 10.3390/ijms21124472] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Accepted: 06/20/2020] [Indexed: 12/18/2022] Open
Abstract
Cardiovascular diseases, including coronary artery disease, ischemic heart diseases such as acute myocardial infarction and postischemic heart failure, heart failure of other etiologies, and cardiac arrhythmias, belong to the leading causes of death. Activation of capsaicin-sensitive sensory nerves by the transient receptor potential vanilloid 1 (TRPV1) capsaicin receptor and other receptors, as well as neuropeptide mediators released from them upon stimulation, play important physiological regulatory roles. Capsaicin-sensitive sensory nerves also contribute to the development and progression of some cardiac diseases, as well as to mechanisms of endogenous stress adaptation leading to cardioprotection. In this review, we summarize the role of capsaicin-sensitive afferents and the TRPV1 ion channel in physiological and pathophysiological functions of the heart based mainly on experimental results and show their diagnostic or therapeutic potentials. Although the actions of several other channels or receptors expressed on cardiac sensory afferents and the effects of TRPV1 channel activation on different non-neural cell types in the heart are not precisely known, most data suggest that stimulation of the TRPV1-expressing sensory nerves or stimulation/overexpression of TRPV1 channels have beneficial effects in cardiac diseases.
