Abstract
OBJECTIVES Noninvasive remote ischemic preconditioning (RIPC) is a practical, acceptable, and feasible conditioning technique reported to provide cardioprotection in myocardial ischemia-reperfusion injury (MIRI). It has been well-reported that quercetin possesses antioxidant and anti-inflammatory properties. This study investigates the modification of the cardioprotective response of RIPC by quercetin. METHODS Adult Wistar rats were randomized into 12 groups of six animals each. MIRI was induced by subjecting the isolated hearts of Wistar rats to global ischemia for 30 min, succeeded by reperfusion of 120 min after mounting on the Langendorff PowerLab apparatus. Hind limb RIPC was applied in four alternate cycles of ischemia and reperfusion of 5 min each by tying the pressure cuff before isolation of hearts. RESULTS MIRI was reflected by significantly increased infarct size, LDH-1, and CK-MB, TNF-α, TBARS, and decreased GSH, catalase, and hemodynamic index, and modulated Nrf2. Pretreatment of quercetin (25 and 50 mg/kg; i.p.) significantly attenuated the MIRI-induced cardiac damage and potentiated the cardioprotective response of RIPC at the low dose. Pretreatment of ketamine (10 mg/kg; i.p.), an mTOR-dependent autophagy inhibitor, significantly abolished the cardioprotective effects of quercetin and RIPC. CONCLUSIONS The findings highlight the modification of the cardioprotective effect of RIPC by quercetin and that quercetin protects the heart against MIRI through multiple mechanisms, including mTOR-dependent activation of autophagy and Nrf-2 activation.

Boovarahan SR, Kurian GA. Ischemic preconditioning modulates the DNA methylation process of the rat heart to provide tolerance to withstand ischemia reperfusion injury and its associated mitochondrial dysfunction. 3 Biotech 2024; 14:121.

Abstract
DNA methylation plays a crucial role in the pathogenesis of myocardial ischemia reperfusion injury(I/R) and the I/R injury can be combated effectively by ischemia preconditioning (IPC), but the role is DNA methylation in this process is unknown. In this study, we uncovered the role of ischemic preconditioning (IPC)- mediated cardioprotection of rat myocardium by using a Langendorff rat heart model with 30 min of ischemia followed by 60 min of reperfusion. Heart conditioned with short cycles of ischemia and reperfusion (IPC procedure) prior to I/R protocol significantly reduced the I/R-induced global DNA hypermethylation level by 32% and the DNMT activity by 33% while rendering cardioprotection. Blocking the PI3K pathway via wortmannin not only negates the cardio-protection by IPC, but also increases the methylation of DNA by 75%. Besides, the correlation analysis showed a negative relationship between PI3K gene expression and the global DNA methylation level (r = - 0.8690, p = 0.0419) in IPC-treated rat hearts. Moreover, the global level DNA hypomethylation induced by IPC exhibited a regulatory effect on the genes involved in I/R pathology mediators like apoptosis (Caspase3), mitochondrial function (PGC 1α, TFAM, ND1) and oxidative stress (CuZnSOD, SOD2), and their corresponding function. The present study results provide novel evidence for the involvement of DNA methylation in the IPC procedure, and suggest DNA methylation as one of the potential therapeutic targets regulated by ischemic preconditioning in rat hearts subjected to ischemia reperfusion.

Abstract
Ischemia reperfusion (I/R) is a common pathological process which occurs mostly in organs like the heart, brain, kidney, and lung. The injury caused by I/R gradually becomes one of the main causes of fatal diseases, which is an urgent clinical problem to be solved. Although great progress has been made in therapeutic methods, including surgical, drug, gene therapy, and transplant therapy for I/R injury, the development of effective methods to cure the injury remains a worldwide challenge. In recent years, exosomes have attracted much attention for their important roles in immune response, antigen presentation, cell migration, cell differentiation, and tumor invasion. Meanwhile, exosomes have been shown to have great potential in the treatment of I/R injury in organs. The study of the exosome-mediated signaling pathway can not only help to reveal the mechanism behind exosomes promoting reperfusion injury recovery, but also provide a theoretical basis for the clinical application of exosomes. Here, we review the research progress in utilizing various exosomes from different cell types to promote the healing of I/R injury, focusing on the classical signaling pathways such as PI3K/Akt, NF-κB, Nrf2, PTEN, Wnt, MAPK, toll-like receptor, and AMPK. The results suggest that exosomes regulate these signaling pathways to reduce oxidative stress, regulate immune responses, decrease the expression of inflammatory cytokines, and promote tissue repair, making exosomes a competitive emerging vector for treating I/R damage in organs.

Abstract
Exosomes are the smallest subset of extracellular signaling vesicles secreted by most cells with the ability to communicate with other tissues and cell types over long distances. Their use in regenerative medicine has gained tremendous momentum recently due to their ability to be utilized as therapeutic options for a wide array of diseases/conditions. Over 5000 publications are currently being published yearly on this topic, and this number is only expected to dramatically increase as novel therapeutic strategies continue to be developed. Today exosomes have been applied in numerous contexts including neurodegenerative disorders (Alzheimer's disease, central nervous system, depression, multiple sclerosis, Parkinson's disease, post-traumatic stress disorders, traumatic brain injury, peripheral nerve injury), damaged organs (heart, kidney, liver, stroke, myocardial infarctions, myocardial infarctions, ovaries), degenerative processes (atherosclerosis, diabetes, hematology disorders, musculoskeletal degeneration, osteoradionecrosis, respiratory disease), infectious diseases (COVID-19, hepatitis), regenerative procedures (antiaging, bone regeneration, cartilage/joint regeneration, osteoarthritis, cutaneous wounds, dental regeneration, dermatology/skin regeneration, erectile dysfunction, hair regrowth, intervertebral disc repair, spinal cord injury, vascular regeneration), and cancer therapy (breast, colorectal, gastric cancer and osteosarcomas), immune function (allergy, autoimmune disorders, immune regulation, inflammatory diseases, lupus, rheumatoid arthritis). This scoping review is a first of its kind aimed at summarizing the extensive regenerative potential of exosomes over a broad range of diseases and disorders.

Abstract
Cardiovascular disease (CVD) significantly impacts global society since it is the leading cause of death and disability worldwide, and extracellular vesicle (EV)-based therapies have been extensively investigated. EV delivery is involved in mediating the progression of CVDs and has great potential to be biomarker and therapeutic molecular carrier. Besides, EVs from stem cells and cardiac cells can effectively protect the heart from various pathologic conditions, and then serve as an alternative treatment for CVDs. Moreover, the research of using EVs as delivery carriers of therapeutic molecules, membrane engineering modification of EVs, or combining EVs with biomaterials further improves the application potential of EVs in clinical treatment. However, currently there are only a few articles summarizing the application of EVs in CVDs. This review provides an overview of the role of EVs in the pathogenesis and diagnosis of CVDs. It also focuses on how EVs promote the repair of myocardial injury and therapeutic methods of CVDs. In conclusion, it is of great significance to review the research on the application of EVs in the treatment of CVDs, which lays a foundation for further exploration of the role of EVs, and clarifies the prospect of EVs in the treatment of myocardial injury.

Exosomal HSP90 induced by remote ischemic preconditioning alleviates myocardial ischemia/reperfusion injury by inhibiting complement activation and inflammation. BMC Cardiovasc Disord 2023; 23:58. [PMID: 36726083 PMCID: PMC9890892 DOI: 10.1186/s12872-023-03043-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 01/05/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND/AIMS The activation of the complement system and subsequent inflammatory responses are important features of myocardial ischemia/reperfusion (I/R) injury. Exosomes are nanoscale extracellular vesicles that play a significant role in remote ischemic preconditioning (RIPC) cardioprotection. The present study aimed to test whether RIPC-induced plasma exosomes (RIPC-Exo) exert protective effects on myocardial I/R injury by inhibiting complement activation and inflammation and whether exosomal heat shock protein 90 (HSP90) mediates these effects. METHODS Rat hearts underwent 30 min of coronary ligation followed by 2 h of reperfusion. Plasma exosomes were isolated from RIPC rats and injected into the infarcted myocardium immediately after ligation. Sixty rats were randomly divided into Sham, I/R, I/R + RIPC-Exo (50 µg/µl), and RIPC-Exo + GA (geldanamycin, 1 mg/kg, administration 30 min before ligation) groups. Cardiomyocyte apoptosis, the release of myocardial markers (LDH, cTnI and CK-MB), infarct size, the expression of HSP90, complement component (C)3, C5a, c-Jun N-terminal kinase (JNK), interleukin (IL)-1β, tumor necrosis factor (TNF)-alpha and intercellular adhesion molecule -1 (ICAM-1) were assessed. RESULTS RIPC-Exo treatment significantly reduced I/R-induced cardiomyocyte apoptosis, the release of myocardial markers (LDH, cTnI and CK-MB) and infarct size. These beneficial effects were accompanied by decreased C3 and C5a expression, decreased inflammatory factor levels (IL-1β, TNF-α, and ICAM-1), decreased JNK and Bax, and increased Bcl-2 expression. Meanwhile, the expression of HSP90 in the exosomes from rat plasma increased significantly after RIPC. However, treatment with HSP90 inhibitor GA significantly reversed the cardioprotection of RIPC-Exo, as well as activated complement component, JNK signalling and inflammation, indicating that HSP90 in exosomes isolated from the RIPC was important in mediating the cardioprotective effects during I/R. CONCLUSION Exosomal HSP90 induced by RIPC played a significant role in cardioprotection against I/R injury, and its function was in part linked to the inhibition of the complement system, JNK signalling and local and systemic inflammation, ultimately alleviating I/R-induced myocardial injury and apoptosis by the upregulation of Bcl-2 expression and the downregulation of proapoptotic Bax.

Abstract
BACKGROUND Exosomes released into the plasma after brief cardiac ischaemia mediate subsequent cardioprotection. Whether donor exosomes can provide cardioprotection to recipients with chronic heart failure, which confers the highest perioperative risk, is unknown. We examined whether ischaemic preconditioning (IPC)-induced plasma exosomes exerted cardioprotection after their transfer from normal donors to post-infarcted failing hearts. METHODS Plasma exosomes were obtained from adult rats after IPC or sham. An exosome inhibitor GW4869 was administrated before IPC in an in vivo model of ischaemia/reperfusion (I/R) injury in normal rats. The IPC exosomes or control exosomes from normal donor rats were perfused to the normal or post-infarcted failing rat hearts before ischaemia in Langendorff perfusion experiments. Infarct size, cardiac enzymes, cardiac function, and pro-survival kinases were quantified. RESULTS The IPC stimulus increased the release of exosomes, whereas GW4869 inhibited the rise of plasma exosomes. Pre-treatment with GW4869 reversed IPC-mediated cardioprotection against in vivo I/R injury. In the Langendorff perfusion experiments, IPC exosomes from normal donor rats reduced mean infarct size from 41.05 (1.87)% to 31.43 (1.81)% and decreased lactate dehydrogenase activity in the post-infarcted failing rat hearts. IPC exosomes but not control exosomes activated pro-survival kinases in the heart tissues. CONCLUSIONS Ischaemic preconditioning-induced exosomes from normal rats can restore cardioprotection in heart failure after myocardial infarction, which is associated with activation of pro-survival protein kinases. These results suggest a potential perioperative therapeutic role for ischaemic preconditioning-induced exosomes.

Abstract
Despite the significant decline in mortality, cardiovascular diseases are still the leading cause of death worldwide. Among them, myocardial infarction (MI) seems to be the most important. A further decline in the death rate may be achieved by the introduction of molecularly targeted drugs. It seems that the components of the PI3K/Akt signaling pathway are good candidates for this. The PI3K/Akt pathway plays a key role in the regulation of the growth and survival of cells, such as cardiomyocytes. In addition, it has been shown that the activation of the PI3K/Akt pathway results in the alleviation of the negative post-infarct changes in the myocardium and is impaired in the state of diabetes. In this article, the role of this pathway was described in each step of ischemia and subsequent left ventricular remodeling. In addition, we point out the most promising substances which need more investigation before introduction into clinical practice. Moreover, we present the impact of diabetes and widely used cardiac and antidiabetic drugs on the PI3K/Akt pathway and discuss the molecular mechanism of its effects on myocardial ischemia and left ventricular remodeling.

Abstract
Purpose Angiogenesis is required for improving myocardial function and is a key factor in long-term prognosis after an acute myocardial infarction (AMI). Although exosomes are known to play a crucial role in angiogenesis, the role of peripheral exosomes in angiogenic signal transduction in patients with AMI remains unclear. Here, we explored the effect of exosomes extracted from the peripheral serum of AMI patients on angiogenesis and elucidated the downstream pathways. Patients and Methods Serum exosomes were obtained from patients with AMI (AMI-Exo) and healthy individuals (Con-Exo). The exosomes were cocultured with human umbilical vein endothelial cells (HUVECs) in vitro, with aortic rings ex vivo, and were used to treat mouse hind-limb ischemia and mouse AMI model in vivo. Results AMI-Exo raised HUVEC proliferation, tube formation, and migration, and enhanced microvessel sprouting from aortic rings compared to Con-Exo, both in vitro and ex vivo. Quantitative reverse transcription-polymerase chain reaction revealed that the abundance of miR-126-3p, a crucial regulator of angiogenesis, was increased in AMI-Exo. The inhibition of miR-126-3p decreased the benefits of AMI-Exo treatment, and miR-126-3p upregulation enhanced the benefits of Con-Exo treatment in HUVECs, aortic rings, the mouse hind-limb ischemia model, and the mouse AMI model. Knockdown and overexpression analyses revealed that miR-126-3p regulated angiogenesis in HUVECs by directly targeting tuberous sclerosis complex 1 (TSC1). Moreover, we found that miR-126-3p could inhibit TSC1 expression, which further activated mTORC1 signaling and increased HIF-1α and VEGFA expression, ultimately promoting angiogenesis. Conclusion Collectively, our results provide a novel understanding of the function of exosomes in angiogenesis post AMI. We demonstrated that exosomes from the peripheral serum of AMI patients promote angiogenesis via the miR-126-3p/TSC1/mTORC1/HIF-1α signaling pathway.

Abstract
The majority of cardiovascular deaths are associated with acute coronary syndrome, especially ST-elevation myocardial infarction. Therapeutic reperfusion alone can contribute up to 40 percent of total infarct size following coronary artery occlusion, which is called ischemia-reperfusion injury (IRI). Its size depends on many factors, including the main risk factors of cardiovascular mortality, such as age, sex, systolic blood pressure, smoking, and total cholesterol level as well as obesity, diabetes, and physical effort. Extracellular vesicles (EVs) are membrane-coated particles released by every type of cell, which can carry content that affects the functioning of other tissues. Their role is essential in the communication between healthy and dysfunctional cells. In this article, data on the variability of the content of EVs in patients with the most prevalent cardiovascular risk factors is presented, and their influence on IRI is discussed.

Abstract
Mitochondria are the central target of ischemic preconditioning and postconditioning cardioprotective strategies, which consist of either the application of brief intermittent ischemia/reperfusion (I/R) cycles or the administration of pharmacological agents. Such strategies reduce cardiac I/R injury by activating protective signaling pathways that prevent the exacerbated production of reactive oxygen/nitrogen species, inhibit opening of mitochondrial permeability transition pore and reduce apoptosis, maintaining normal mitochondrial function. Cardioprotection also involves the activation of mitochondrial quality control (MQC) processes, which replace defective mitochondria or eliminate mitochondrial debris, preserving the structure and function of the network of these organelles, and consequently ensuring homeostasis and survival of cardiomyocytes. Such processes include mitochondrial biogenesis, fission, fusion, mitophagy and mitochondrial-controlled cell death. This review updates recent advances in MQC mechanisms that are activated in the protection conferred by different cardiac conditioning interventions. Furthermore, the role of extracellular vesicles in mitochondrial protection and turnover of these organelles will be discussed. It is concluded that modulation of MQC mechanisms and recognition of mitochondrial targets could provide a potential and selective therapeutic approach for I/R-induced mitochondrial dysfunction.

Abstract
ABSTRACT This study aims to investigate the effect and the related mechanisms of bromodomain-containing protein 4 (BRD4) inhibition on myocardial ischemia/reperfusion (I/R) injury. In vivo and in vitro myocardial I/R models were constructed. Expression of BRD4 was examined by RT-qPCR and Western blot. I/R injury was evaluated by analyzing cardiac function and the activity of biochemical markers of myocardial injury. Inflammation and oxidative stress were determined by measuring the levels of myeloperoxidase, TNF-α, IL-6, malondialdehyde, and superoxide dismutase. The activation of the PI3K/AKT signaling pathway was tested by the phosphorylation of p85 and AKT. We found BRD4 was significantly increased in the myocardial tissues after myocardial I/R injury. BRD4 inhibition suppressed the indices of cardiac function and the biochemical markers of myocardial injury. I/R-induced inflammation and oxidative stress were suppressed by shBRD4 in vivo and in vitro. In addition, BRD4 inhibition significantly increased the relative protein expression levels of p-p85, p-AKT T308, and p-AKT S473. In conclusion, this study for the first time demonstrated the protective effect of BRD4 inhibition on myocardial I/R injury in vivo and in vitro, and this effect was related to the suppression of inflammation and oxidative stress through the activation of the PI3K/AKT signaling pathway.

Poria cum Radix Pini Rescues Barium Chloride-Induced Arrhythmia by Regulating the cGMP-PKG Signalling Pathway Involving ADORA1 in Zebrafish. Front Pharmacol 2021; 12:688746.

Abstract
The traditional Chinese medicine Poria cum Radix Pini (PRP) is a fungal medicinal material that has been proven to play an important role in the treatment of arrhythmia. However, the mechanism of its effect on arrhythmia is still unclear. In this study, network pharmacology and metabolomics correlation analysis methods were used to determine the key targets, metabolites and potential pathways involved in the effects of PRP on arrhythmia. The results showed that PRP can significantly improve cardiac congestion, shorten the SV-BA interval and reduce the apoptosis of myocardial cells induced by barium chloride in zebrafish. By upregulating the expression of the ADORA1 protein and the levels of adenosine and cGMP metabolites in the cGMP-PKG signalling pathway, PRP can participate in ameliorating arrhythmia. Therefore, we believe that PRP shows great potential for the treatment of arrhythmia.

Mesenchymal Stem Cell-Derived Exosomes Carry MicroRNA-125a to Protect Against Diabetic Nephropathy by Targeting Histone Deacetylase 1 and Downregulating Endothelin-1. Diabetes Metab Syndr Obes 2021; 14:1405-1418.

Abstract
BACKGROUND Mesenchymal stem cell (MSC)-derived exosomes have seen great advances in human disease control in a minimally invasive manner. This research aimed to explore the function of MSC-derived exosomes in diabetic nephropathy (DN) progression and the molecules involved. METHODS A rat model with DN and rat glomerular mesangial cell (GMC) models treated with high glucose (HG) were established, which were treated with exosomes from adipose-derived-MSCs (adMSCs). The levels of blood glucose, serum creatinine, and urinary protein, the urine albumin-to-creatinine ratio (UACR), kidney weight/body weight, and mesangial hyperplasia and kidney fibrosis in rats were determined. The expression of interleukin-6 (IL-6), collagen I (Col. I), fibronectin (FN), Bax and Bcl-2 in HG-treated GMCs was assessed. The microRNA (miRNA) carried by adMSC-exosomes was identified, and the implicated down-stream molecules were analyzed. RESULTS adMSC-derived exosomes decreased levels of blood glucose, serum creatinine, 24-h urinary protein, UACR and kidney weight/body weight, and they suppressed mesangial hyperplasia and kidney fibrosis in DN rats. The exosomes also suppressed levels of IL6, Col. I and FN in HG-treated GMCs and promoted cell apoptosis. miR-125a was at least partially responsible for the above protective events mediated by adMSC-exosomes. miR-125a directly bound to histone deacetylase 1 (HDAC1), while HDAC1 further regulated endothelin-1 (ET-1) activation. Up-regulation of HDAC1 blocked the functions of adMSC-exosomal miR-125a. CONCLUSION This study suggested that adMSC-derived exosomes inhibit DN progression and alleviate the symptoms by carrying miR-125a, during which HDAC1 and ET-1 were inhibited. This study may provide novel effects into DN treatment.
