Shuxian Ma, Zhenming Dong
The role of OPA1-related mitochondrial fusion in cardiac reperfusion stress has remained elusive. The aim of our study is to explore whether melatonin alleviates cardiac IR injury by modulating OPA1-related mitochondrial fusion. We found that melatonin reduced infarct area, sustained myocardial function and suppressed cardiomyocyte death during cardiac reperfusion stress. Biological studies have revealed that IR-inhibited mitochondrial fusion was largely reversed by melatonin via upregulated OPA1 expression...

We have performed a gene-based association study and detected several important blood pressure (BP)-associated genes. In this study we explored functional variants in these genes by bioinformatics analysis and validated the associations between the functional SNPs and hypertension with public data and our in-house data of 857 cases and 927 controls. We found various functional variants in the BP-associated genes, including missense mutations, phosphorylation-related SNPs. Most of these SNPs were associated with expressions of the local genes...

Previous studies have shown that κ-opioid receptor activation possesses cardioprotection against myocardial ischemia and reperfusion (MI/R) injury. The current study was designed to investigate whether mitochondrial dysfunction following MI/R is regulated by the κ-opioid receptor and to further explore the underlying mechanisms involved. MI/R rat model was established in vivo, and a hypoxia and reoxygenation cardiomyocytes model was utilized in vitro. Mitochondrial morphology and function, as well as myocardial apoptosis were determined...

BACKGROUND: European Guidelines on Myocardial Revascularization recommend clopidogrel loading dose added to acetylsalicylic acid in elective percutaneous coronary interventions (PCI). However, there is few evidence supporting this recommendation and other P2Y12 inhibitors have not been tested in these patients. PURPOSE: To evaluate the effectiveness and safety of different loading doses of clopidogrel and ticagrelor in patients without double antiplatelet therapy and stable coronary disease (SCAD) undergoing elective PCI...

Various tests are available for measuring on-treatment platelet reactivity. The pharmacologically most specific assays are time-consuming and elaborate. A highly specific and convenient assay would be desirable for clinical routine. In this pilot study we aimed to examine the ability of a novel bedside whole-blood assay - ROTEM® platelet - to evaluate platelet inhibition compared to established assays.Platelet reactivity was investigated in 93 patients. 47 patients were on permanent aspirin therapy and 46 on dual antiplatelet therapy (DAPT) with aspirin and clopidogrel...

BACKGROUND: A diet rich in saturated fat and sugars (Western diet, WD) induces myocardial expression of the NLRP3 inflammasome and dysfunction in the mouse. We therefore hypothesized that a diet enriched with an orally available NLRP3 inflammasome inhibitor could prevent WD-induced cardiac dysfunction in the mouse. METHODS: Ten-week old CD-1 male mice were fed WD or Standard diet (SD) for 8 weeks. The compound 16673-34-0, an orally active NLRP3 inhibitor, was added to the diet at concentration of 100 mg/Kg...

Antihypertensive pharmacological treatments focus on use of ACE inhibitors, AT1 receptor antagonists (ARBs) and beta-blockers as single and combined treatments. The effect of single treatments on the mRNA expression of some components of the renin-angiotensin system has been studied, but not the effect of combined treatments. This study determined the expression of the AT1, AT2, B1, B2 receptors and of the enzymes ACE and ACE2 in hypertensive rats treated with captopril-propranolol or losartan-propranolol. Methods: the mRNA expression of the receptors and enzymes was determined by RT-qPCR in the aorta of SHR rats under different treatments...

Clopidogrel is an antiplatelet agent that is indicated for cardiovascular emergencies and procedures. The drug, however, is subject to response variability leading to therapy resistance. In this research, we explored the demographic, clinical and genetic factors associated with clopidogrel resistance. Data analysis among our 280 subjects receiving clopidogrel showed some risk factors that are significantly associated with clopidogrel resistance compared to responders. Those were: female gender (P = 0.021), advanced age (P = 0...

Coronary heart disease (CHD) is a kind of cardiovascular disease which has been causing mortality around the world for decades. Since symptoms of CHD are different in female and male patients and these symptoms occur much later in female patients, CHD is very likely to be under-diagnosed in women. Thus, it is imperative to explore novel diagnostic method for CHD especially for women. Recently, microRNA (miRNA) targeted therapy have attracted much attention as a novel therapeutic method. MiRNAs have been proven as possible markers and targeted agents for diverse diseases...

BACKGROUND: Hypertension is a major cause of left ventricular (LV) diastolic dysfunction. Although β-adrenergic receptor (β-AR) blockers are often used to manage hypertension, the impact of β-AR activation on LV lusitropic effects and hence filling pressures in the hypertensive heart with LV diastolic dysfunction is uncertain. METHODS: Using tissue Doppler imaging and Speckle tracking software, we assessed LV function in isoflurane anesthetised spontaneously hypertensive (SHR) and Dahl salt-sensitive (DSS) rats before and after β-AR activation [isoproterenol (ISO) administration]...

INTRODUCTION AND METHODS: The effects of diazoxide on cardiac hypertrophy and miR-132 expression were characterized in adult rats and in cardiomyocytes. Diazoxide effects on reactive oxygen species (ROS) production and on the cAMP-response element binding (CREB) transcription factor's abundance in cardiomyocytes were also analyzed. ROS measurements used a fluorescent dye. Western blot analysis and quantitative Reverse Transcription Polymerase Chain Reaction were used to measure phosphorylated form of CREB (pCREB) abundance and miR-132 expression, respectively...

We investigated whether resveratrol (RSV) can attenuate obesity and diabetes progression and improve diabetes-induced vascular dysfunction, and we attempted to delineate its underlying mechanisms. Male C57Bl/6 mice were administered a high-fat diet (HFD) for 17 weeks. Mice developed type 2 diabetes with increased body weight, hyperglycemia, hyperinsulinemia, and hyperlipidemia. Oral gavage with RSV significantly reversed the symptoms induced by the HFD. Insulin sensitivity likewise improved after the RSV intervention in these mice...

Vicagrel, a novel acetate analogue of clopidogrel, exerts more potent antiplatelet effect than clopidogrel in rodents. Relevant evidence indicated that aspirin and vicagrel are the drug substrate for carboxylesterase 2. Accordingly, it is deduced that concomitant use of aspirin could attenuate the bioactivation of and platelet response to vicagrel. To clarify whether there could be such an important drug-drug interaction, the differences in both the formation of vicagrel active metabolite H4 and the inhibition of adenosine diphosphate-induced platelet aggregation by vicagrel were measured and compared between mice treated with vicagrel alone or in combination with aspirin...

There is an increase in oxidative stress and apoptosis signaling during the transition from hypertrophy to right ventricular (RV) failure caused by pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT). In this study, it was evaluated the action of copaiba oil on the modulation of proteins involved in RV apoptosis signaling in rats with PAH. Male Wistar rats (±170 g, n = 7/group) were divided into 4 groups: control, MCT, copaiba oil, and MCT + copaiba oil. PAH was induced by MCT (60 mg/kg intraperitoneally) and, 7 days later, treatment with copaiba oil (400 mg/kg by gavage) was given for 14 days...

We previously found that metformin regulates the ion current conducted by the small conductance calcium-activated potassium channels (SK channels) in the atria of rats with type 2 diabetes mellitus (T2DM) as well as the mRNA and protein expression of the SK2 and SK3 subtypes of SK channels. In this study, we hypothesized that the nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4)/p38 mitogen-activated protein kinase (p38MAPK) signaling pathway was involved in the metformin-mediated regulation of SK2 and SK3 expression in the atria of rats with T2DM...

Cerebral ischemia has previously been shown to cause a systemic decrease in levels of the reduced forms of low-molecular-weight aminothiols [cysteine (Cys), homocysteine (Hcy), and glutathione (GSH)] in blood plasma. In this study, we examined the effect of beta-adrenergic receptor (β-AR) antagonists metoprolol (Met) and nebivolol (Neb) on the redox status of these aminothiols during acute cerebral ischemia in rats. We used a model of global cerebral ischemia (bilateral occlusion of common carotid arteries with hypotension lasting for 10 minutes)...

Cannabinoid CB2 receptor agonists are under investigation for clinical use. At the same time, synthetic cannabinoids have been implicated in a number of deaths. One cause of death is thought to be cardiac arrest subsequent to extreme tachycardia. Central mechanisms are thought to play a role in this, with CB1 but not CB2 receptors thought to mediate central effects. However, the direct effects of cannabinoids on the heart are less well understood. We therefore tested the effects of cannabinoids on isolated rat atria to test whether activation of myocardial CB1 and CB2 receptors could contribute to tachycardia...

Prasugrel and ticagrelor are recommended over clopidogrel in patients with ST-elevation myocardial infarction (STEMI). In this registry analysis, we compared efficacy and safety of ticagrelor and prasugrel P2Y12 inhibition in patients with STEMI. We included 318 patients in this single-center analysis. Twelve-month follow-up was conducted during ambulatory care at our department. Patients were on dual antiplatelet therapy with aspirin and ticagrelor or prasugrel during the follow-up period. Prescription of prasugrel or ticagrelor, respectively, was according to the preference of the treating physician...
