Kamisah Y, Che Hassan HH. Role of Trimetazidine in Ameliorating Endothelial Dysfunction: A Review. Pharmaceuticals (Basel) 2024; 17:464. [PMID: 38675424 PMCID: PMC11054808 DOI: 10.3390/ph17040464] [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: 03/12/2024] [Revised: 04/01/2024] [Accepted: 04/04/2024] [Indexed: 04/28/2024] Open
Abstract
Endothelial dysfunction is a hallmark of cardiovascular diseases, contributing to impaired vasodilation, altered hemodynamics, and atherosclerosis progression. Trimetazidine, traditionally used for angina pectoris, exhibits diverse therapeutic effects on endothelial dysfunction. This review aims to elucidate the mechanisms underlying trimetazidine's actions and its potential as a therapeutic agent for endothelial dysfunction and associated cardiovascular disorders. Trimetazidine enhances vasodilation and hemodynamic function by modulating endothelial nitric oxide synthase activity, nitric oxide production, and endothelin-1. It also ameliorates metabolic parameters, including reducing blood glucose, mitigating oxidative stress, and dampening inflammation. Additionally, trimetazidine exerts antiatherosclerotic effects by inhibiting plaque formation and promoting its stability. Moreover, it regulates apoptosis and angiogenesis, fostering endothelial cell survival and neovascularization. Understanding trimetazidine's multifaceted mechanisms underscores its potential as a therapeutic agent for endothelial dysfunction and associated cardiovascular disorders, warranting further investigation for clinical translation.

Abstract
Peptides are recognized as highly effective and safe bioactive ingredients. However, t their practical application is limited and hampered by harsh conditions for practical drug delivery. Hence, a novel peptide nanocarrier of copper peptide (GHK-Cu) encapsulation developed by liposome technology combined with the classical Chinese concept of rigidity and flexibility. Different polyols were selected as modification ligands for phospholipid bilayers to construct a nano drug-carrying system with high loading rate, good stability and biocompatibility. In vitro, this complex not only significantly retarded the release ability of copper peptides, but also enabled copper peptides to be effectively resistant to enzymatic degradation. Furthermore, cellular experiments showed that this system mainly regulates Nrf2, SIRT1, and PEG2/COX-2-related signaling pathways, thus effectively counteracting cellular inflammation, senescence, and apoptosis from oxidative damage. Interestingly, a green, non-toxic, efficient and convenient antioxidant system was developed for the prevention and deceleration of skin aging.

Abstract
OBJECTIVES The aim of this study was to repurpose a drug for the treatment of bipolar depression. METHODS A gene expression signature representing the overall transcriptomic effects of a cocktail of drugs widely prescribed to treat bipolar disorder was generated using human neuronal-like (NT2-N) cells. A compound library of 960 approved, off-patent drugs were then screened to identify those drugs that affect transcription most similar to the effects of the bipolar depression drug cocktail. For mechanistic studies, peripheral blood mononuclear cells were obtained from a healthy subject and reprogrammed into induced pluripotent stem cells, which were then differentiated into co-cultured neurons and astrocytes. Efficacy studies were conducted in two animal models of depressive-like behaviours (Flinders Sensitive Line rats and social isolation with chronic restraint stress rats). RESULTS The screen identified trimetazidine as a potential drug for repurposing. Trimetazidine alters metabolic processes to increase ATP production, which is thought to be deficient in bipolar depression. We showed that trimetazidine increased mitochondrial respiration in cultured human neuronal-like cells. Transcriptomic analysis in induced pluripotent stem cell-derived neuron/astrocyte co-cultures suggested additional mechanisms of action via the focal adhesion and MAPK signalling pathways. In two different rodent models of depressive-like behaviours, trimetazidine exhibited antidepressant-like activity with reduced anhedonia and reduced immobility in the forced swim test. CONCLUSION Collectively our data support the repurposing of trimetazidine for the treatment of bipolar depression.

[PMID: 37932729 PMCID: PMC10629039 DOI: 10.1186/s12944-023-01952-7] [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: 07/09/2023] [Accepted: 10/18/2023] [Indexed: 11/08/2023] Open
Abstract
BACKGROUND Autonomic remodeling of the atria plays a pivotal role in the development of atrial fibrillation (AF) and exerts a substantial influence on the progression of this condition. Hyperlipidemia is a predisposing factor for AF, but its effect on atrial nerve remodeling is unclear. The primary goal of this study was to explore the possible mechanisms through which the consumption of a high-fat diet (HFD) induces remodeling of atrial nerves, and to identify novel targets for clinical intervention. METHODS Cell models were created in vitro by subjecting cells to palmitic acid (PA), while rat models were established by feeding them a high-fat diet. To investigate the interplay between cardiomyocytes and nerve cells in a co-culture system, we utilized Transwell cell culture plates featuring a pore size of 0.4 μm. The CCK-8 assay was employed to determine cell viability, fluorescent probe DCFH-DA and flow cytometry were utilized for measuring ROS levels, JC-1 was used to assess the mitochondrial membrane potential, the Griess method was employed to measure the nitric oxide (NO) level in the supernatant, a fluorescence-based method was used to measure ATP levels, and MitoTracker was utilized for assessing mitochondrial morphology. The expression of pertinent proteins was evaluated using western blotting (WB) and immunohistochemistry techniques. SNAP was used to treat nerve cells in order to replicate a high-NO atmosphere, and the level of nitroso was assessed using the iodoTMT reagent labeling method. RESULTS The study found that cardiomyocytes' mitochondrial morphology and function were impaired under high-fat stimulation, affecting nitric oxide (NO) production through the CRIF1/SIRT1/eNOS axis. In a coculture model, overexpression of eNOS in cardiomyocytes increased NO expression. Moreover, the increased Keap1 nitrosylation within neuronal cells facilitated the entry of Nrf2 into the nucleus, resulting in an augmentation of P21 transcription and a suppression of proliferation. Atrial neural remodeling occurred in the HFD rat model and was ameliorated by increasing myocardial tissue eNOS protein expression with trimetazidine (TMZ). CONCLUSIONS Neural remodeling is triggered by high-fat stimulation, which decreases the production of NO through the CRIF1/eNOS/P21 axis. Additionally, TMZ prevents neural remodeling and reduces the occurrence of AF by enhancing eNOS expression.

Abstract
Bipolar disorder's core feature is the pathological disturbances in mood, often accompanied by disrupted thinking and behavior. Its complex and heterogeneous etiology implies that a range of inherited and environmental factors are involved. This heterogeneity and poorly understood neurobiology pose significant challenges to existing drug development paradigms, resulting in scarce treatment options, especially for bipolar depression. Therefore, novel approaches are needed to discover new treatment options. In this review, we first highlight the main molecular mechanisms known to be associated with bipolar depression-mitochondrial dysfunction, inflammation and oxidative stress. We then examine the available literature for the effects of trimetazidine in said alterations. Trimetazidine was identified without a priori hypothesis using a gene-expression signature for the effects of a combination of drugs used to treat bipolar disorder and screening a library of off-patent drugs in cultured human neuronal-like cells. Trimetazidine is used to treat angina pectoris for its cytoprotective and metabolic effects (improved glucose utilization for energy production). The preclinical and clinical literature strongly support trimetazidine's potential to treat bipolar depression, having anti-inflammatory and antioxidant properties while normalizing mitochondrial function only when it is compromised. Further, trimetazidine's demonstrated safety and tolerability provide a strong rationale for clinical trials to test its efficacy to treat bipolar depression that could fast-track its repurposing to address such an unmet need as bipolar depression.

Effects of Trimetazidine on Right Ventricular Function and Ventricular Remodeling in Patients with Pulmonary Artery Hypertension: A Randomised Controlled Trial. J Clin Med 2023; 12:jcm12041571. [PMID: 36836104 PMCID: PMC9962764 DOI: 10.3390/jcm12041571] [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: 12/29/2022] [Revised: 01/21/2023] [Accepted: 02/04/2023] [Indexed: 02/18/2023] Open
Abstract
BACKGROUND Pulmonary artery hypertension (PAH) is a chronic and progressive disease. Although current therapy has improved the disease prognosis, PAH has a poor survival rate. The key feature leading to disease progression and death is right ventricular (RV) failure. METHODS AND RESULTS We assessed the role of trimetazidine, a fatty acid beta-oxidation (FAO) inhibitor, in right ventricular function, remodeling, and functional class in PAH patients, with a placebo-controlled double-blind, case-crossover trial. Twenty-seven PAH subjects were enrolled, randomized, and assigned to trimetazidine or placebo for three months and then reallocated to the other study arm. The primary endpoint was RV morphology and function change after three months of treatment. Secondary endpoints were the change in exercise capacity assessed by a 6 min walk test after three months of treatment and the change in pro-BNP and Galectin-3 plasma levels after three months. Trimetazidine use was safe and well-tolerated. After three months of treatment, patients in the trimetazidine group showed a small but significant reduction of RV diastolic area, and a substantial increase in the 6 min walk distance (418 vs. 438 mt, p = 0.023), without significant changes in biomarkers. CONCLUSIONS A short course of trimetazidine is safe and well-tolerated on PAH patients, and it is associated with significant increases in the 6MWT and minor but significant improvement in RV remodeling. The therapeutic potential of this drug should be evaluated in larger clinical trials.

Abstract
BACKGROUND In coronary artery disease (CAD), reduction of perfusion in coronary arteries is followed by increases of oxidative stress and decreases of adenosine triphosphate reserve. In this condition, trimetazidine (TMZ), a metabolic anti-ischemic agent, seems to be an ideal therapeutic agent because it increases mitochondrial adenosine triphosphate production. STUDY QUESTION To evaluate the impact of TMZ on oxidative stress, inflammation, endothelial dysfunction, and long-term prognosis in CAD. STUDY DESIGN Patients with CAD with symptoms not adequately controlled were enrolled consecutively for a period of 18 months. MEASURES AND OUTCOMES Five hundred seventy patients with CAD were enrolled in a prospective study and divided into 4 groups in relation with the type of CAD and the addition of TMZ to optimal medical therapy (OMT). The impact of TMZ added to OMT on oxidative stress (total antioxidant status, antioxidized low-density lipoprotein antibodies, and antimyeloperoxidase antibodies), endothelial dysfunction (flow-mediated dilatation and von Willebrand factor activity), and inflammation (C-reactive protein and fibrinogen) at 6 months and on long-term prognosis in CAD in comparison with OMT at 5 years of follow-up was evaluated. RESULTS At 6 months, TMZ added to OMT significantly decreased the incidence of oxidative stress in CAD (P < 0.03) and reduced endothelial dysfunction and inflammation only in non-ST-elevation acute coronary syndrome (NSTE-ACS, P < 0.04). TMZ added to OMT with or without interventional/surgical vascularization led to decreased readmission for NSTE-ACS and heart failure (P < 0.05) in all patients with CAD and a significantly reduced incidence of cardiovascular death, acute myocardial infarction, and stroke (P < 0.05) in patients with NSTE-ACS at 5 years of follow-up. CONCLUSIONS In patients with NSTE-ACS, TMZ added to OMT with or without interventional and/or surgical reperfusion reduced oxidative stress, endothelial dysfunction, inflammation, and major acute cardiovascular events, whereas in patients with chronic coronary syndrome, TMZ decreased oxidative stress and readmission for ACS and heart failure.

Abstract
OBJECTIVES This systematic review and meta-analysis assesses the utility of trimetazidine (TMZ) to prevent contrast induced nephropathy (CIN) in patients with renal insufficiency undergoing coronary angiography and angioplasty. MATERIALS AND METHODS This meta-analysis was formulated and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of databases was conducted by 2 researchers independently for clinical trials, comparing hydration plus TMZ vs conventional hydration alone for prevention of CIN through January 2020. All patients had renal insufficiency (defined as GFR < 89 ml/minute/1.73 m2) and the outcome of interest was the incidence of contrast induced acute kidney injury. The odds ratio (OR) was estimated with 95% confidence interval (CI). Heterogeneity was reported with the I2 statistic, using a fixed-effects model, and >50% of I2 was considered to be statistically significant. RESULTS Eleven studies, 1611 patients, met the inclusion/exclusion criteria: 797 patients comprised the TMZ plus hydration group and the remaining 814 patients comprised the control (hydration only) group. Heterogeneity was low I2 = 0%, P = .84, and the heterogeneity of each study was also low. The incidence of CIN in the TMZ plus hydration group was 6.6% (53/797), while the incidence of CIN in the control (hydration only) group was 20% (165/814). Pooled analysis of all studies showed TMZ reduced incidence of CIN compared to saline hydration alone (OR risk 0.30, 95% CI 0.21, 0.42, P < .0001). CONCLUSION TMZ added to hydration reduces CIN in renal insufficiency patients undergoing coronary angiography.

Abstract
Endothelial progenitor cell (EPC) transplantation is a safe and effective method to treat acute myocardial infarction (AMI). However, oxidative stress leads to the death of a large number of EPCs in the early stage of transplantation, severely weakening the therapeutic effect. Previous studies demonstrated that microRNAs regulate the biological function of EPCs. The aim of the current study was to investigate the effect of microRNA on the biological function of EPCs under oxidative stress. Quantitative reverse transcription PCR was performed to detect the expression of miR-126, miR-508-5p, miR-150, and miR-16 in EPCs from rats, among which miR-126 showed a relatively higher expression. Treatment with H2O2 decreased miR-126 expression in EPCs in a dose-dependent manner. EPCs were further transfected with miR-126 mimics or inhibitors, followed by H2O2 treatment. Overexpression of miR-126 enhanced the proliferation, migration, and tube formation of H2O2-treated EPCs. MiR-126 overexpression also inhibited reactive oxygen species and malondialdehyde levels and enhanced superoxide dismutase levels, as well as increased angiopoietin (Ang)1 expression and decreased Ang2 expression in H2O2-treated EPCs. Moreover, miR-126 participated in the regulation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/glycogen synthase kinase 3β (GSK3β) and extracellular signal-regulated kinase 1/2 (ERK1/2) signaling in EPCs, where both pathways were activated after miR-126 overexpression in H2O2-treated EPCs. Overall, we showed that miR-126 promoted the biological function of EPCs under H2O2-induced oxidative stress by activating the PI3K/Akt/GSK3β and ERK1/2 signaling pathway, which may serve as a new therapeutic approach to treat AMI.

Abstract
Heart failure is a systemic syndrome caused by multiple pathological factors. Current treatments do not have satisfactory outcomes. Several basic studies have revealed the protective effect of trimetazidine on the heart, not only by metabolism modulation but also by relieving myocardial apoptosis, fibrosis, autophagy, and inflammation. Clinical studies have consistently indicated that trimetazidine acts as an adjunct to conventional treatments and improves the symptoms of heart failure. This review summarizes the basic pathological changes in the myocardium, with an emphasis on the alteration of cardiac metabolism in the development of heart failure. The clinical application of trimetazidine in heart failure and the mechanism of its protective effects on the myocardium are carefully discussed, as well as its main adverse effects. The intention of this review is to highlight this treatment as an effective alternative against heart failure and provide additional perspectives for future studies.

Abstract
BACKGROUND This study investigated the effect and the possible mechanism of trimetazidine in atherosclerosis. MATERIAL AND METHODS We established an atherosclerotic rat model by high-fat diet and vitamin D injection. Rats were separated into 3 different groups: control, atherosclerosis, and trimetazidine (n=10). The aortic artery was isolated and its morphological features were examined by hematoxylin and eosin (HE) staining. Serum low-density lipoprotein cholesterol (LDL-c), total cholesterol (TC), and triglycerides (TG) were analyzed using an automatic biochemical analyzer. Human aortic smooth muscle cells (HASMCs) were cultured and divided into 5 groups: no treatment, H₂O₂ treatment only, trimetazidine preincubation before H₂O₂ treatment, oxidized low-density lipoprotein (oxLDL) treatment only, and trimetazidine preincubation before oxLDL treatment. HASMCs proliferation was tested using the Cell Counting Kit-8. Reactive oxygen species (ROS) and malondialdehyde (MDA) levels, superoxide dismutase (SOD) activity of the aortic artery, and HASMCs were measured using commercially available kits. RESULTS HE staining assay showed that trimetazidine suppressed the progression of atherosclerosis and reduced foam cell formation in the aortic artery without affecting serum lipid levels. HASMCs proliferation assay revealed that trimetazidine alleviated the inhibitory effect of H₂O₂ on HASMCs proliferation and inhibited oxLDL-induced proliferation of HASMCs. Moreover, trimetazidine ameliorated ROS up-regulation elicited by H₂O₂ or oxLDL in HASMCs. Additionally, trimetazidine restored SOD activity and reduced MDA content of HASMCs. CONCLUSIONS Trimetazidine suppressed the progression of atherosclerosis by enhancing energy value, decreasing ROS level of aortic artery, modulating HASMCs proliferation, and reducing oxidative stress in HASMCs.

Abstract
BACKGROUND/AIMS Cardiac rupture (CR) is a catastrophic complication of acute myocardial infarction (MI). At present, there are no effective pharmacological strategies for preventing post-MI rupture. Here we investigated the effect of trimetazidine (TMZ) on post-MI CR. METHODS MI models were induced by left coronary artery ligation in male C57BL/6 mice. Animals allocated to the rupture incidence were closely monitored for 7 days; autopsy was performed once animals were found dead to determine the reason of death. Heart function was detected by echocardiography. Oxidative stress markers and matrix metalloproteinases (MMPs) were analyzed by Western Blotting. RESULTS TMZ markedly reduced the post-MI CR incidence of mice. We found that the expression of metalloproteinase (MMP) -2 and MMP-9 in the TMZ-treated group was significantly lower than the saline-treated group. Further, TMZ markedly attenuated MI-induced oxidative stress. To investigate the mechanism of the effect of TMZ on CR, we pretreated H9c2 cells with H2 O2 and found that TMZ treatment markedly decreased H2 O2 -induced MMP-2 and MMP-9 expression. TMZ prevents CR through inhibition of oxidative stress, which is attributable to the down-regulation of MMP-2, MMP-9 expression. CONCLUSIONS Our findings indicate that TMZ suppresses oxidative stress, inhibits MMP-2 and MMP-9 expression, and prevents CR in mice with MI.

J Mol Med (Berl) 2018; 96:791-806. [PMID: 29955901 DOI: 10.1007/s00109-018-1664-3] [Citation(s) in RCA: 63] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2018] [Revised: 06/16/2018] [Accepted: 06/21/2018] [Indexed: 12/25/2022]
Abstract
Trimetazidine (TMZ) has been demonstrated to have protective effects against myocardial ischemia/reperfusion (MI/R) injury. In the present study, we investigated the effects and the underlying mechanisms of TMZ on autophagy during MI/R in vivo and in vitro. In the in vivo study, an animal model of MI/R was induced by coronary occlusion. TMZ (20 mg/kg/day) protected the rat hearts from MI/R-induced heart failure by increasing ejection fraction and fractional shortening and decreasing end-systolic volume, end-diastolic volume, left ventricular (LV) internal diameter at systole, and LV internal diameter at diastole; it alleviated myocardial injury and oxidative stress by decreasing LDH, creatine kinase MB isoenzyme, ROS, and MDA levels and increasing SOD and glutathione peroxidase levels in plasma. TMZ also reduced myocardial infarct size and apoptosis. Moreover, TMZ markedly inhibited MI/R-induced autophagy by decreasing the protein and messenger RNA levels of LC3-II, Beclin1, ATG5, and ATG7 and the number of autophagosomes and by involving the AKT/mTOR pathway. Further, in the in vitro experiments, H9c2 cells were incubated with TMZ (40 μM) to explore the direct effects of TMZ following exposure to hypoxia and reoxygenation (H/R). TMZ increased cell viability and the concentration of intracellular SOD and inhibited H/R-induced cell apoptosis and ROS production. Moreover, TMZ decreased the number of autophagosomes and autophagy-related protein expression; it also upregulated p-AKT and p-mTOR expression. In addition, TMZ augmented Bcl-2 protein expression and diminished Bax protein expression, the Bax/Bcl-2 rate, and cleaved caspase-3 level. However, these effects on H9c2 cells were notably abolished by the PI3K inhibitor LY294002. In conclusion, our results showed that TMZ inhibited I/R-induced excessive autophagy and apoptosis, which was, at least partly, mediated by activating the AKT/mTOR pathway. KEY MESSAGES TMZ improved cardiac function, alleviated myocardial injury and oxidative stress, and reduced the myocardial infarct area and apoptosis. TMZ inhibited MI/R-induced myocardial autophagy, H/R-induced H9c2 cell apoptosis, and autophagy flux. The effect of TMZ on autophagy was repressed by LY294002. TMZ protected against MI/R injury by inhibiting excessive autophagy via activating the AKT/mTOR pathway.

Abstract
Systemic inflammatory response syndrome is a complex pathophysiologic and immunologic response to an insult. Sepsis is a life-threatening condition happening when the body's response to infection causes injury to its own tissues and organs. Stem cell therapy is a new approach to modulate immune responses. Mesenchymal stem cells (MSCs) establish a regenerative niche by secreting secretome and modulating immune responses. MSC secretome can be leveraged for therapeutic applications if production of secretary molecules were optimized. Pharmacological preconditioning using small molecules can increase survival of MSCs after transplantation. The aim of this study was to investigate the effect of secretome of human embryonic-derived mesenchymal stem cells (hESC-MSCs) preconditioned with MG-132,Trimetazidine (TMZ) and Diazoxide (DZ) on immunomodulatory efficiency of these cells in Lipo polysaccharide (LPS) challenged mice models. Mice were injected intraperitoneally with LPS and groups of animals were intraperitoneally given 1 ml 30× secretome 6 h after LPS injection. Serum levels of biochemical parameters were then measured by an auto analyser and serum inflammatory cytokine levels were analysed using commercially available RayBio Mouse Inflammation Antibody Array. Ultimately, histopathology and survival studies were conducted. The results showed that TMZ and DZ-conditioned medium significantly increasing the survival and improvement of histopathological score. We found that MG-132-conditioned medium failed to show significant outcomes. This study demonstrated that human MSC secretome has the potential to control inflammation.

Abstract
Diabetes is associated with an increased risk of cardio-vascular disease. A decrease in the number and functionality of endothelial progenitor cells (EPCs) leads to reduced endothelial repair and the development of cardiovascular disease. The aim of the present study was to explore the effect and underlying mechanisms of nuclear factor erythroid 2-related factor 2 (Nrf2) on EPC dysfunction caused by diabetic mellitus. The biological functions of EPCs in streptozotocin-induced diabetic mice were evaluated, including migration, proliferation, angiogenesis and the secretion of vascular endothelial growth factor (VEGF), stromal-derived growth factor (SDF) and nitric oxide (NO). Oxidative stress levels in diabetic EPCs were also assessed by detecting intracellular reactive oxygen species (ROS), superoxide dismutase (SOD) and malondialdehyde (MDA). EPC senescence was evaluated by measuring p16 and b-gal expression and observing the senescence-associated secretory phenotype. In addition, the function of EPCs and level of oxidative stress were assessed following Nrf2 silencing or activation. Nrf2 silencing resulted in a decrease of EPC biological functions, accelerated cell senescence and increased oxidative stress, as indicated by ROS and MDA upregulation accompanied with decreased SOD activity. Furthermore, Nrf2 silencing inhibited migration, proliferation and secretion in EPCs, while it increased oxidative stress and cell senescence. Nrf2 activation protected diabetic EPCs against the effects of oxidative stress and cell senescence, ameliorating the biological dysfunction of EPCs derived from mice with diabetes. In conclusion, Nrf2 overexpression protected against oxidative stress-induced functional damage in EPCs derived from diabetic mice by regulating cell senescence.

Abstract
Background Contrast-induced nephropathy (CIN) is one of the common hospital-acquired acute renal failures. The purpose of this study was to investigate whether Coenzyme Q10 (CoQ10) and trimetazidine (TMZ) can prevent the occurrence of CIN after elective cardiac catheterization in patients with coronary artery disease complicated with renal dysfunction. Methods Consecutive coronary artery disease patients with renal insufficiency scheduled for coronary angiography were enrolled in randomized, paralleled, double-blind, controlled trial. The development of CIN was occurrence at the 48 or 72 h after the procedure. The changes of serum creatinine (SCr), eGFR, and Cys-C within 72 h after the procedure were measured and compared. In vivo contrast medium (CM)-induced acute kidney injury (AKI) animal model was established, and CoQ10 plus TMZ was orally administrated to evaluate its renal protective effect. Results 150 patients with renal insufficiency were enrolled finally. CIN occurred in 21 (14.00%) of the 150 patients. 72 h after the procedure, the incidence of CIN was significantly lower in CoQ10 plus TMZ group compared with control group (6.67 vs. 21.3%, p = 0.01). No cardiac death occurred in this study. No side effects were observed after administration of CoQ10 and TMZ. In vivo test demonstrated that CoQ10 and TMZ could significantly reduce the concentration of blood urea nitrogen (BUN) and SCR induced by CM i.v. injection, as well as tubular pathological injuries. Meanwhile, CoQ10 and TMZ could significantly reduce the oxidation stress in kidneys from CM-AKI animals. Conclusion CoQ10 plus TMZ could decrease the incidence of CIN in patients with renal insufficiency undergoing elective cardiac catheterization, and their effect may be due to its strong anti-oxidation effect.

Abstract
OBJECTIVE We aimed to evaluate the additive benefit of trimetazidine with well-known antispasmodic agents such as calcium channel blockers and nitrate in patients with significant coronary artery spasm (CAS) as assessed by acetylcholine provocation test up to 5 years. METHODS A total 1727 patients with significant CAS were enrolled. They were divided into two groups: a trimetazidine group (trimetazidine, diltiazem, and nitrate, n = 695), and control group (diltiazem and nitrate, n = 473). After propensity score matching analysis, two matched groups (441 pairs, n = 882, C-statistic = 0.673) were generated. The individual and composite clinical end points [mortality, myocardial infarction (MI), revascularization, cerebrovascular accident (CVA), major adverse cardiac events (MACE), major adverse cardiac or cerebrovascular events (MACCE), and recurrent angina] were assessed up to 5 years for the two groups. RESULTS At 5 years, there were similar incidences of individual and composite hard endpoints including mortality, MI, revascularization, CVA, MACE, MACCE, and recurrent angina in the two groups. CONCLUSIONS Additional long-term (5-year) treatment with trimetazidine in combination with diltiazem and nitrate in patients with significant CAS was not associated with improved clinical outcomes compared with combination therapy with diltiazem and nitrate only (without trimetazidine).

BACKGROUND Acute viral myocarditis is an inflammatory disease with global impact. Although it may resolve spontaneously, its course is not easily predicted, and there is a paucity of specific treatment options available with proven efficacy. Coenzyme Q10 (CQ10) and trimetazidine possess antioxidant and antiinflammatory effects. METHODS We examined the therapeutic efficacy of these agents in acute viral myocarditis both individually and in combination. Patients were blinded and randomized to receive CQ10 (n = 42), trimetazidine (n = 39), or CQ10 + trimetazidine (n = 43) treatment. RESULTS Serum inflammatory and oxidative stress marker and myocardial enzyme levels, and heart function were measured. Both CQ10 and trimetazidine decreased inflammatory and oxidative stress biomarker levels compared with baseline measurements. However, combination therapy with CQ10 and trimetazidine showed a significantly more powerful effect not only on markers of inflammation and oxidative stress, but also on left ventricular systolic function and troponin, compared with either treatment alone. CONCLUSION This study confirmed the beneficial effect of CQ10 and trimetazidine individually, but demonstrated a superior effect of combining the therapies on cardiac left ventricular ejection fraction, and biochemical markers of myocardial damage in acute viral myocarditis.

Abstract
BACKGROUND Hypoxic preconditioning may be a key influence on functions of endothelial progenitor cells (EPCs). MATERIAL AND METHODS To investigate the role and mechanism of the Notch-Jagged1 pathway on endothelial progenitor cells in hypoxic preconditioning, endothelial progenitor cells were randomly allocated into 5 groups: 1 Normoxic control group; 2 Hypoxic blank group; 3 Hypoxic+25 μM DAPT group; 4 Hypoxic+50 μM DAPT group; 5 Hypoxic+100 μM DAPT group. After reoxygenation, protein and mRNA levels of Jagged1 were measured by Western blot and quantitative RT-PCR. The MTT test was used to assess proliferation. ELISA was used to measure NO and VEGF secretion. RESULTS Hypoxic preconditioning treatment significantly upregulated both protein and mRNA levels of Jagged1 in endothelial progenitor cells. It also enhanced proliferation ability and elevated secretion of NO and VEGF. Furthermore, after blocking the Notch pathway by using DAPT, Jagged1 expression and EP proliferation, migration, and secretion of NO and VEGF were decreased in a dose-dependent manner. CONCLUSIONS Our results suggest the Notch-Jagged1 pathway enhances EPCs proliferation and secretion ability during hypoxic preconditioning.

Abstract
Effect of trimetazidine (20 and 30 mg/kg) on elevated plus maze behavior of rodents was assessed in the genetic and pharmacological anxiety models. Single intraperitoneal injection of trimetazidine in a dose of 20 mg/kg prevented anxiety development in highly emotional male BALB/c mice and increased the time spent in open arms of the maze. In outbred male rats receiving 10% ethanol solution for 20 weeks, trimetazidine administered intraperitoneally in a dose of 20 mg/kg for 28 days abolished ethanol withdrawal-induced anxiogenesis developed against the background of 4-week alcohol deprivation: it increased the time spent in open arms, the number of entries into open arms, and total locomotor activity in the maze. Anxiolytic properties of trimetazidine were not inferior to those of the non-benzodiazepine anxiolytic Afobazole (fabomotizole) in acute and chronic administration.

Abstract
We investigated the involvement of glycogen synthase kinase-3β (GSK3β) and the voltage-dependent anion channel (VDAC) in livers subjected to cold ischemia-reperfusion injury (I/R) associated with orthotopic liver transplantation (OLT). Rat livers were preserved in University of Wisconsin (UW) and Institute Georges Lopez (IGL-1) solution, the latter enriched or not with trimetazidine, and then subjected to OLT. Transaminase (ALT) and HMGB1 protein levels, glutamate dehydrogenase (GLDH), and oxidative stress (MDA) were measured. The AKT protein kinase and its direct substrates, GSK3β and VDAC, as well as caspases 3, 9, and cytochrome C and reticulum endoplasmic stress-related proteins (GRP78, pPERK, ATF4, and CHOP), were determined by Western blot. IGL-1+TMZ significantly reduced liver injury. We also observed a significant phosphorylation of AKT, which in turn induced the phosphorylation and inhibition of GSK3β. In addition, TMZ protected the mitochondria since, in comparison with IGL-1 alone, we found reductions in VDAC phosphorylation, apoptosis, and GLDH release. All these results were correlated with decreased ER stress. Addition of TMZ to IGL-1 solution increased the tolerance of the liver graft to I/R injury through inhibition of GSK3β and VDAC, contributing to ER stress reduction and cell death prevention.

Abstract
Chemotaxis, integrates diverse intra- and inter-cellular molecular processes into a purposeful patho-physiological response; the operatic rules of which, remain speculative. Here, I surmise, that superoxide anion induced directional motility, in a responding cell, results from a quasi pathway between the stimulus, surrounding interstitium, and its biochemical repertoire. The epochal event in the mounting of an inflammatory response, is the extravascular transmigration of a phagocyte competent cell towards the site of injury, secondary to the development of a lamellipodium. This stochastic-to-markovian process conversion, is initiated by the cytosolic-ROS of the damaged cell, but is maintained by the inverse association of a de novo generated pool of self-sustaining superoxide anions and sub-critical hydrogen peroxide levels. Whilst, the exponential rise of O2(.-) is secondary to the focal accumulation of higher order lipid raft-Rac1/2-actin oligomers; O2(.-) mediated inactivation and redistribution of ECSOD, accounts for the minimal concentration of H2O2 that the phagocyte experiences. The net result of this reciprocal association between ROS/ RNS members, is the prolonged perturbation and remodeling of the cytoskeleton and plasma membrane, a prelude to chemotactic migration. The manuscript also describes the significance of stochastic modeling, in the testing of plausible molecular hypotheses of observable phenomena in complex biological systems.

Abstract
BACKGROUND Reduced expression of sarcoplasmic reticulum calcium-transporting ATPase isoform 2a (SERCA2a) has been shown to play a significant role in the cardiac dysfunction of obese animal models. It was reported recently that SUMOylation enhances the stability and activity of SERCA2a. We hypothesized that SERCA2a-SUMOylation might be involved in obesity-mediated reduction of SERCA2a. METHOD AND RESULTS Trimetazidine (TMZ), the drug that inhibits fatty acid oxidation, was used in diet-induced obese (DIO) rats and palmitic acid (PA)-treated cardiomyocytes. The intensity of SERCA2a-SUMOylation and proteins involved in SERCA2a-SUMOylation were investigated in vivo and in vitro. DIO rats presented cardiac dysfunction, which was alleviated by TMZ treatment. Reductions of SERCA2a protein and the intensity of SERCA2a-SUMOylation were observed in DIO rats and PA-treated cardiomyocytes. These reductions were partially restored by TMZ. However, TMZ itself did not alter the intensity of SERCA2a-SUMOylation in control cardiomyocytes. The variations of protein and messenger RNA levels of Ubiquitin carrier protein 9 are in accordance with the intensity of SERCA2a-SUMOylation. Whereas the other proteins involved in SERCA2a-SUMOylation were not changed by DIO and PA. CONCLUSIONS TMZ alleviates the DIO- and PA-induced reductions of SERCA2a-SUMOylation. Ubiquitin carrier protein 9 is involved in the reductions.

Abstract
Renal ischemia reperfusion (I/R) injury, which occurs during renal surgery or transplantation, is the major cause of acute renal failure. Trimetazidine (TMZ), an anti-ischemic drug, protects kidney against the deleterious effects of I/R. However its protective mechanism remains unclear. The aim of this study is to examine the relevance of Akt, endothelial nitric oxide synthase (eNOS), and hypoxia inducible factor-1α (HIF-1α) on TMZ induced protection of kidneys against I/R injury. Wistar rats were subjected to 60 min of warm renal ischemia followed by 120 min of reperfusion, or to intraperitoneal injection of TMZ (3 mg/kg) 30 min before ischemia. In sham operated group renal pedicles were only dissected. Compared to I/R, TMZ treatment decreased lactate dehydrogenase (845 ± 13 vs. 1028 ± 30 U/L). In addition, creatinine clearance and sodium reabsorption rates reached 105 ± 12 versus 31 ± 11 μL/min/g kidney weight and 95 ± 1 versus 68 ± 5%, respectively. Besides, we noted a decrease in malondialdehyde concentration (0.33 ± 0.01 vs. 0.59 ± 0.03 nmol/mg of protein) and an increase in glutathione concentration (2.6 ± 0.2 vs. 0.93 ± 0.16 µg GSH/mg of protein), glutathione peroxidase (95 ± 4 vs. 61 ± 3 µg GSH/min/mg of protein), and superoxide dismutase (25 ± 3 vs. 11 ± 2 U/mg of protein) and catalase (91 ± 12 vs. 38 ± 9 μmol/min/mg of protein) activities. Parallely, we noted a significant increase in p-Akt, eNOS, nitrite and nitrate (18 ± 2 vs. 8 ± 0.1 pomL/mg of protein), HIF-1α (333 ± 48 vs. 177 ± 14 µg/mg of protein) and heme oxygenase-1 (HO-1) levels regarding I/R. TMZ treatment improves renal tolerance to warm I/R. Such protection implicates an activation of Akt/eNOS signaling pathway, HIF-1α stabilization and HO-1 activation.

Abstract
Increased oxidative stress contributes to the functional impairment of endothelial progenitor cells (EPCs), the pivotal players in the servicing of the endothelial cell lining. Several evidences suggest that decreasing oxidative stress by natural compounds with antioxidant properties may improve EPCs bioactivity. Here, we investigated the effects of Lisosan G (LG), a Triticum Sativum grain powder, and Lady Joy (LJ), a bean lysate, on function of EPCs exposed to oxidative stress. Peripheral blood mononuclear cells were isolated and plated on fibronectin-coated culture dishes; adherent cells, identified as early EPCs, were pre-treated with different concentrations of LG and LJ and incubated with hydrogen peroxide (H2O2). Viability, senescence, adhesion, ROS production and antioxidant enzymes gene expression were evaluated. Lysate-mediated Nrf-2 (nuclear factor (erythroid-derived 2)-like 2)/ARE (antioxidant response element) activation, a modulator of oxidative stress, was assessed by immunocytochemistry. Lady Joy 0.35-0.7 mg/ml increases EPCs viability; pre-treatment with either LG 0.7 mg/ml and LJ 0.35-0.7 mg/ml protect EPCs viability against H2O2-induced injury. LG 0.7 and LJ 0.35-0.7 mg/ml improve EPCs adhesion; pre-treatment with either LG 0.35 and 0.7 mg/ml or LJ 0.35, 0.7 and 1.4 mg/ml preserve adhesiveness of EPCs exposed to H2O2. Senescence is attenuated in EPCs incubated with lysates 0.35 mg/ml. After exposure to H2O2, LG pre-treated cells show a lower senescence than untreated EPCs. Lysates significantly decrease H2O2-induced ROS generation. Both lysates increase glutathione peroxidase-1 and superoxide dismutase-2 (SOD-2) expression; upon H2O2 exposure, pre-treatment with LJ allows higher SOD-2 expression. Heme oxigenase-1 increases in EPCs pre-treated with LG even upon H2O2 exposure. Finally, incubation with LG 0.7 mg/ml results in Nrf-2 translocation into the nucleus both at baseline and after the oxidative challenge. Our data suggest a protective effect of lysates on EPCs exposed to oxidative stress through the involvement of antioxidant systems. Lisosan G seems to activate the Nrf-2/ARE pathways.

Abstract
PURPOSE OF REVIEW Great effort has been devoted to elucidate the molecular mechanisms by which inflammasome in macrophages contributes to atherosclerosis. Inflammasome in vascular endothelial cells and its causal relationship with endothelial dysfunction in atherosclerosis are less understood. Here, we review the recent studies of inflammasome and its activation in endothelial cells, and highlight such endothelial inflammatory response in atherosclerosis. RECENT FINDINGS Inflammasomes are critical effectors in innate immunity, and their activation in macrophages and the arterial wall contributes to atherogenesis. Sterol regulatory element-binding protein 2, a master regulator in cholesterol biosynthesis, can be activated in a noncanonical manner, which leads to the activation of the NOD-like receptor family pyrin domain-containing protein inflammasome in macrophages and endothelial cells. Results from in-vitro and in-vivo models suggest that sterol regulatory element-binding protein 2 is a key molecule in aggravating proinflammatory responses in endothelial cells and promoting atherosclerosis. SUMMARY The SREBP-induced NOD-like receptor family pyrin domain-containing protein inflammasome and its instigation of innate immunity is an important contributor to atherosclerosis. Elucidating the underlying mechanisms will expand our understanding of endothelial dysfunction and its dynamic interaction with vascular inflammation. Furthermore, targeting SREBP-inflammasome pathways can be a therapeutic strategy for attenuating atherosclerosis.

Abstract
Metabolic and cardiovascular disease patients have increased plasma levels of lipids and, specifically, of palmitate, which can be toxic for several tissues. Trimetazidine (TMZ), a partial inhibitor of lipid oxidation, has been proposed as a metabolic modulator for several cardiovascular pathologies. However, its mechanism of action is controversial. Given the fact that TMZ is able to alter mitochondrial metabolism, we evaluated the protective role of TMZ on mitochondrial morphology and function in an in vitro model of lipotoxicity induced by palmitate. We treated cultured rat cardiomyocytes with BSA-conjugated palmitate (25 nM free), TMZ (0.1-100 μM), or a combination of both. We evaluated mitochondrial morphology and lipid accumulation by confocal fluorescence microscopy, parameters of mitochondrial metabolism (mitochondrial membrane potential, oxygen consumption rate [OCR], and ATP levels), and ceramide production by mass spectrometry and indirect immunofluorescence. Palmitate promoted mitochondrial fission evidenced by a decrease in mitochondrial volume (50%) and an increase in the number of mitochondria per cell (80%), whereas TMZ increased mitochondrial volume (39%), and decreased mitochondrial number (56%), suggesting mitochondrial fusion. Palmitate also decreased mitochondrial metabolism (ATP levels and OCR), while TMZ potentiated all the metabolic parameters assessed. Moreover, pretreatment with TMZ protected the cardiomyocytes from palmitate-induced mitochondrial fission and dysfunction. TMZ also increased lipid accumulation in cardiomyocytes, and prevented palmitate-induced ceramide production. Our data show that TMZ protects cardiomyocytes by changing intracellular lipid management. Thus, the beneficial effects of TMZ on patients with different cardiovascular pathologies can be related to modulation of the mitochondrial morphology and function.
