Abstract
Cardiovascular disease (CVD) remains the leading global cause of mortality. Acute myocardial infarction (AMI) refers to acute myocardial ischemia resulting from thrombosis secondary to coronary atherosclerosis, which poses a major threat to human health. Clinically, timely revascularization (reperfusion) represents the basis of clinical treatment for AMI. However, secondary myocardial ischemia-reperfusion injury (MIRI) caused by reperfusion often exacerbates damage, representing a major challenge in clinical practice. Mitochondria represent essential organelles for maintaining cardiac function and cellular bioenergetics in MIRI. In recent years, the role of mitochondrial quality control (MQC) in maintaining cell homeostasis and mediating MIRI has been extensively studied. This review provides a concise overview of MQC mechanisms at the molecular, organelle, and cellular levels and their possible complex regulatory network in MIRI. In addition, potential treatment strategies targeting MQC to mitigate MIRI are summarized, highlighting the gap between current preclinical research and clinical transformation. Overall, this review provides theoretical guidance for further research and clinical translational studies.

Abstract
Myocardial ischemia/reperfusion (I/R) injury is a major global health problem with high rates of mortality and disability, which is more severe in patients with diabetes. Substantial researches have documented that diabetic myocardium are more susceptible to I/R injury, but many current intervention strategies against myocardial I/R injury have limited effectiveness in diabetic hearts. Caveolin-3 (Cav-3) is the signature protein of caveolae and serves as a signal integration and transduction platform in the plasma membrane of cardiomyocytes, which plays a vital role in myocardial functions, metabolism and protection of multiple conditioning strategies against I/R injury. Nevertheless, numerous studies have revealed that the expression of Cav-3 is impaired in diabetic hearts, which contributes to increased vulnerability of myocardium to I/R injury and resistance to protective conditioning strategies. In this review, we outline the basic structure and function of Cav-3, emphatically present the unique role of Cav-3 as a signal integration and transduction element in diabetic myocardial I/R injury and discuss its therapeutic perspective in strategies against myocardial I/R injury in diabetes.

Int J Surg 2024; 110:7311-7330. [PMID: 39093878 PMCID: PMC11573079 DOI: 10.1097/js9.0000000000001975] [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: 05/30/2024] [Accepted: 07/14/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Myocardial ischemia-reperfusion (I/R) injury significantly impacts recovery in both cardiac and noncardiac surgeries, potentially leading to severe cardiac dysfunction. Sevoflurane, a volatile anesthetic, is reputed for its protective effects against myocardial I/R injury, although evidence remains inconclusive. This systematic review and meta-analysis aim to clarify the cardioprotective efficacy of sevoflurane. METHODS The systematic search of databases including Medline, Embase, Scopus, and Web of Science, was supplemented with a manual search to retrieve studies using rat or mouse models of myocardial I/R injury, comparing sevoflurane pretreatment (≥24 h before I/R), preconditioning (within 24 h before I/R), or postconditioning (after I/R) against nontreated controls. The outcomes were cardiac function, myocardial infarct size, apoptosis, inflammation, oxidative stress, and cardiac biomarkers. Using the random effects model, standardized mean differences (SMD) were pooled to perform meta-analyses. RESULTS Fifty-one studies, encompassing 8189 subjects, were included in the meta-analysis. Pretreatment with Sevoflurane significantly reduced infarct size. Sevoflurane preconditioning exhibited positive effects on left ventricular parameters and ejection fraction, and reduced infarct size, apoptosis, and oxidative stress. Postconditioning with Sevoflurane demonstrated improvements in cardiac function, including enhanced left ventricular parameters and reduced infarct size, apoptosis, inflammation, oxidative stress, and cardiac biomarkers. CONCLUSION Sevoflurane demonstrates a significant protective effect against myocardial I/R injury in animal models. These findings support the potential clinical utility of sevoflurane as an anesthetic choice in preventing and managing myocardial I/R injury during surgeries.

[PMID: 39122228 DOI: 10.1016/j.exger.2024.112540] [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: 02/05/2024] [Revised: 07/30/2024] [Accepted: 08/06/2024] [Indexed: 08/12/2024]
Abstract
BACKGROUND Myocardial ischemia-reperfusion (MI/R) can lead to structural and functional abnormalities in the hippocampal neurons of the brain. High-mobility group box-l (HMGB1) is implicated in the activation of immune cells and the stimulation of inflammatory responses. However, the specific role of HMGB1 in cognitive impairment induced by MI/R in elderly rats has yet to be elucidated. METHODS Elderly rats underwent surgical procedures to induce MI/R. To evaluate the learning and memory abilities of these rats, a water maze test and a new-object recognition test were administered. Nissl staining was utilised to examine hippocampal neuron damage. Enzyme-linked immunosorbent assay, western blotting, and real-time quantitative polymerase chain reaction (RT-qPCR) analyses were conducted to measure the expression levels of HMGB1, inflammatory cytokines, and molecular pathways. RESULTS The study found that MI/R induced cognitive impairment in elderly rats. There was an observed increase in serum HMGB1 levels, along with elevated concentrations of pro-inflammatory cytokines in the plasma and hippocampus, accompanied by a decrease in anti-inflammatory cytokines. Moreover, substantial damage was evident in the hippocampal neurons of rats exposed to MI/R. In the brains of these rats, there was an increased expression of HMGB1, the receptor for advanced glycation end products (RAGE), toll-like receptor 4 (TLR4), phosphorylated p65, interleukin-1β (IL-1β), IL-6, IL-23, tumour necrosis factor-α (TNF-α), caspase-3, and Bax. In contrast, the expression of B-cell lymphoma 2 was decreased. The RT-qPCR analyses indicated elevated levels of HMGB1, RAGE, TLR4, IL-1β, IL-6, IL-23, TNF-α, caspase-3, and Bax mRNA. CONCLUSION The increased concentration of serum and hippocampal inflammatory factors in the brains of elderly rats subjected to MI/R suggests that cognitive impairment may be induced through the activation of the HMGB1/TLR4/NF-κB signalling pathway.

Abstract
INTRODUCTION The comorbidities of ischemic heart disease (IHD) and diabetes mellitus (DM) compromise the protection of the diabetic heart from ischemia/reperfusion (I/R) injury. We hypothesized that manipulation of reperfusion injury salvage kinase (RISK) and survivor activating factor enhancement (SAFE) pathways might protect the diabetic heart, and intervention of these pathways could be a new avenue for potentially protecting the diabetic heart. METHODS All hearts were subjected to 30-min ischemia and 30-min reperfusion. During reperfusion, hearts were exposed to molecules proven to protect the heart from I/R injury. The hemodynamic data were collected using suitable software. The infarct size, troponin T levels, and protein levels in hearts were evaluated. RESULTS Both cyclosporine-A and nitric oxide donor (SNAP) infusion at reperfusion protected 4-week diabetic hearts from I/R injury. However, 6-week diabetic hearts were protected only by SNAP, but not cyclosporin-A. These treatments significantly (p < 0.05) improved cardiac hemodynamics and decreased infarct size. CONCLUSIONS The administration of SNAP to diabetic hearts protected both 4- and 6-week diabetic hearts; however, cyclosporine-A protected only the 4-week diabetic hearts. The eNOS/GLUT-4 pathway executed the SNAP-mediated cardioprotection.

Abstract
Diabetic cardiomyopathy describes decreased myocardial function in diabetic patients in the absence of other heart diseases such as myocardial ischemia and hypertension. Recent studies have defined numerous molecular interactions and signaling events that may account for deleterious changes in mitochondrial dynamics and functions influenced by hyperglycemic stress. A metabolic switch from glucose to fatty acid oxidation to fuel ATP synthesis, mitochondrial oxidative injury resulting from increased mitochondrial ROS production and decreased antioxidant capacity, enhanced mitochondrial fission and defective mitochondrial fusion, impaired mitophagy, and blunted mitochondrial biogenesis are major signatures of mitochondrial pathologies during diabetic cardiomyopathy. This review describes the molecular alterations underlying mitochondrial abnormalities associated with hyperglycemia and discusses their influence on cardiomyocyte viability and function. Based on basic research findings and clinical evidence, diabetic treatment standards and their impact on mitochondrial function, as well as mitochondria-targeted therapies of potential benefit for diabetic cardiomyopathy patients, are also summarized.

Int Immunopharmacol 2023; 120:110219. [PMID: 37270931 DOI: 10.1016/j.intimp.2023.110219] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 04/04/2023] [Accepted: 04/18/2023] [Indexed: 06/06/2023]
Abstract
OBJECTIVE Sevoflurane is suggested to exert protective functions against myocardial ischemia-reperfusion injury (MIRI). However, the particular mechanism remains elusive. Therefore, this research explored the mechanism of sevoflurane in MIRI-induced damage and pyroptosis. METHODS Subsequent to gain-or loss-of-function assays or/and sevoflurane treatment, the MIRI model was developed in rats. Cardiac function and body and heart weight of rats were evaluated, followed by measurement of apoptosis and creatine kinase MB (CK-MB), lactate dehydrogenase (LDH), and pyroptosis-related protein levels. After loss-of-function assays or/and sevoflurane treatment in human cardiomyocytes (HCMs), the hypoxia/reoxygenation (H/R) model was constructed. In HCMs, cell viability, apoptosis, and pyroptosis-related proteins were detected. Circular RNA PAN3 (circPAN3), microRNA (miR)-29b-3p, and stromal cell-derived factor 4 (SDF4) expression was determined in rat myocardial tissues and HCMs. Mechanistically, interactions among circPAN3, miR-29b-3p, and SDF4 were analyzed. RESULTS MIRI modeling increased miR-29b-3p expression and diminished circPAN3 and SDF4 expression in H/R-treated HCMs and MIRI rats, which was nullified by sevoflurane preconditioning. Mechanistically, circPAN3 negatively targeted miR-29b-3p to upregulate SDF4. Moreover, sevoflurane preconditioning reduced heart weight/body weight ratio, LDH, CK-MB, myocardial infarct size, left ventricular end-diastolic pressure, apoptosis, and pyroptosis, while elevating the increase and decrease of left ventricular pressure (±dp/dt max) and left ventricular systolic pressure in MIRI rats. In addition, sevoflurane preconditioning augmented viability while diminishing apoptosis and pyroptosis in H/R-treated HCMs. Moreover, circPAN3 silencing or miR-29b-3p overexpression abrogated alleviatory effects of sevoflurane on myocardial injury and pyroptosis in vitro. CONCLUSION Sevoflurane treatment ameliorated myocardial injury and pyroptosis in MIRI via circPAN3/miR-29b-3p/SDF4 axis.

Speckle-tracking echocardiography provides sensitive measurements of subtle early alterations associated with cardiac dysfunction in T2DM rats. BMC Cardiovasc Disord 2023; 23:266.

Abstract
BACKGROUND Diabetic cardiomyopathy results in cardiac structural and functional abnormalities. Previous studies have demonstrated that inhibiting the RhoA/ROCK signalling pathway increases the injury resistance of cardiomyocytes. The early detection of cardiac structural and functional alterations may facilitate an improved understanding of the pathophysiologic progress and guide therapy. This study aimed to identify the optimal diagnostic measures for the subtle early alterations of cardiac dysfunction in type 2 diabetes mellitus (T2DM) rats. METHODS Twenty-four rat models were divided into four groups and received treatments for 4 weeks: the CON group (control rats), the DM group (T2DM rats), the DMF group (T2DM rats receiving fasudil) and the CONF group (control rats receiving fasudil) group. Left ventricular (LV) structure was quantified by histological staining and transmission electron microscopy. LV function and myocardial deformation were assessed by high-frequency echocardiography. RESULTS Treatment with fasudil, a ROCK inhibitor, significantly protected against diabetes-induced myocardial hypertrophy, fibrosis and mitochondrial dysfunction. Impaired LV performance was found in T2DM rats, as evidenced by significant reductions in the ejection fraction (EF), fractional shortening (FS) and the mitral valve (MV) E/A ratio (which decreased 26%, 34% and 20%, respectively). Fasudil failed to improve the conventional ultrasonic parameters in T2DM rats, but the myocardial deformation measured by speckle-tracking echocardiography (STE) were significantly improved (global circumferential strain, GCS: P = 0.003; GCS rate, GCSR: P = 0.021). When receiver operating characteristic (ROC) curves were used in combination with linear regression analysis, STE parameters were found to be characterized by both optimal prediction of cardiac damage [AUC (95% CI): fractional area change, FAC: 0.927 (0.744, 0.993); GCS: 0.819 (0.610, 0.945); GCSR: 0.899 (0.707, 0.984)] and stronger correlations with cardiac fibrosis (FAC: r = -0.825; GCS: r = 0.772; GCSR: r = 0.829) than conventional parameters. CONCLUSION The results suggest that STE parameters are more sensitive and specific than conventional parameters in predicting the subtle cardiac functional changes that occur in the early stage, providing new insight into the management of diabetic cardiomyopathy.

Abstract
Background Myocardial ischemia-reperfusion injury (MIRI) is characterized by its high incidence rate and mortality. miR-199a-3p is thought to be strongly linked with the development of some myocardial diseases, but the influence of miR-199a-3p in MIRI remains unclear. Methods AC16 cells were used. The concentrations of mammalian target of rapamycin (mTOR), light chain 3 II/light chain 3 I, and Beclin-1 were detected with western blotting and qRT-PCR. The binding site between mTOR and miR-199a-3p was evaluated via luciferase report assay. Cell apoptosis was evaluated through flow cytometry. Results Knockdown of miR-199a-3p accelerated the myocardial cell injury after L-oxygen treatment. Increased expression of mTOR and suppressed autophagy were observed after knockdown of miR-199a-3p. Knockdown of miR-199a-3p or overexpression of mTOR greatly aggravated cell injury through inhibiting autophagy. Conclusions. This study might be helpful for the therapeutic method of MIRI through by regulating miR-199a-3p/mTOR.

Abstract
Objective Myocardial ischemia/reperfusion injury (IRI) is a common and serious complication in clinical practice. Sevoflurane conditionings have been identified to provide a protection against myocardial IRI in animal experiments, but their true clinical benefits remain controversial. Here, we aimed to analyze the preclinical evidences obtained in animal models of myocardial IRI and explore the possible reasons for controversial clinical benefits. Methods Our primary outcome was the difference in mean infarct size between the sevoflurane and control groups in animal models of myocardial IRI. After searching the databases of PubMed, Embase, Web of Science, and the Cochrane Library, a systematic review retrieved 37 eligible studies, from which 28 studies controlled comparisons of sevoflurane preconditioning (SPreC) and 40 studies controlled comparisons of sevoflurane postconditioning (SPostC) that were made in a pooled random-effects meta-analysis. In total, this analysis included data from 313 control animals and 536 animals subject to sevoflurane conditionings. Results Pooled estimates for primary outcome demonstrated that sevoflurane could significantly reduce the infarct size after myocardial IRI whether preconditioning [weighted mean difference (WMD): −18.56, 95% CI: −23.27 to −13.85, P < 0.01; I2 = 94.1%, P < 0.01] or postconditioning (WMD: −18.35, 95% CI: −20.88 to −15.83, P < 0.01; I2 = 90.5%, P < 0.01) was performed. Interestingly, there was significant heterogeneity in effect size that could not be explained by any of the prespecified variables by meta-regression and stratified analysis. However, sensitivity analysis still identified the cardioprotective benefits of sevoflurane conditionings with robust results. Conclusion Sevoflurane conditionings can significantly reduce infarct size in in-vivo models of myocardial IRI. Given the fact that there is a lack of consistency in the quality and design of included studies, more well-performed in-vivo studies with the detailed characterization of sevoflurane protocols, especially studies in larger animals regarding cardioprotection effects of sevoflurane, are still required.
