microRNAs (miRNAs) are well-known, powerful regulators of gene expression, and their potential to serve as circulating biomarkers is widely accepted. In cardiovascular disease (CVD), numerous studies have suggested miRNAs as strong circulating biomarkers with high diagnostic as well as prognostic power. In coronary artery disease (CAD) and heart failure (HF), miRNAs have been suggested as reliable biomarkers matching up to established protein-based such as cardiac troponins (cT) or natriuretic peptides. Also, in other CVD entities, miRNAs were identified as surprisingly specific biomarkers - with great potential for clinical applicability, especially in those entities that lack specific protein-based biomarkers such as atrial fibrillation (AF) and acute pulmonary embolism (APE)...

Obesity paradox (OP) describes a widely observed clinical finding of improved cardiovascular fitness and survival in some overweight or obese patients. The molecular mechanisms underlying OP remain enigmatic partly due to a lack of animal models mirroring OP in patients. Using apolipoprotein E knockout (ApoE-/-) mice on high-fat (HF) diet as an atherosclerotic obesity model, we demonstrated: 1) microRNA-155 (miRNA-155, miR-155) is significantly upregulated in aortas of ApoE-/- mice; and miR-155 deficiency in ApoE-/- mice inhibits atherosclerosis; 2) ApoE-/-/miR-155-/- (DKO) mice show HF diet-induced obesity, adipocyte hypertrophy and present with nonalcoholic fatty liver disease (NAFLD); 3) DKO mice demonstrate HF diet-induced elevations of plasma leptin, resistin, fed-state and fasting insulin, increased expression of adipogenic transcription factors, but lack glucose intolerance and insulin resistance...

Heart failure (HF) is an endpoint resulting from a number of disease states. The prognosis for HF patients is poor with survival rates precipitously low. Energy metabolism is centrally linked to the development of HF and it involves the proteomic remodeling of numerous pathways, many of which are targeted to the mitochondrion. MicroRNA (miRNA) are noncoding RNAs that influence post-transcriptional gene regulation. MiRNA have garnered considerable attention for their ability to orchestrate changes to the transcriptome and ultimately the proteome, during HF...

BACKGROUND: Aging populations show higher incidences of myocardial infarction (MI) and heart failure (HF). Cardiac remodeling post-MI leads to progressive impaired cardiac function caused by a disarray of several processes including derailed autophagy. Microribonucleic acids (miRNAs) are known to be key players in cardiovascular disease but their involvement in cardiac autophagy and aging is not well understood. OBJECTIVES: This study sought to identify new miRNA candidates that regulate cardiac autophagy and aging...

Heart failure (HF) is the inability of the heart to provide sufficient cardiac output for the energy demands of the body. Over the last decades, our understanding of the role of microRNAs (miRNAs), a class of small non-coding RNA regulators of gene expression at the post-transcriptional level, in cardiovascular diseases has expanded at a rapid rate. Importantly, multiple miRNAs have been specifically implicated in the progression of HF. Growing evidence suggests that miRNAs regulate central metabolic pathways and thus are highly implicated in the maintenance of energy homeostasis...

Heart failure is a major public health problem especially in the aging population (≥65 years old), affecting nearly 5 million Americans and 15 million European people. Effective management of heart failure (HF) depends on a correct and rapid diagnosis. Presently, BNP (brain natriuretic peptide) or N-terminal pro-brain natriuretic peptide (NT-proBNP) assay is generally accepted by the international community for diagnostic evaluation and risk stratification of patients with HF. However, regardless of its widespread clinical use, BNP is still encumbered by reduced specificity...

MicroRNAs play key roles in the regulation of diverse cellular processes and during cardiovascular disease development and progression, such as myocardial infarction (MI) and heart failure (HF). A recent manuscript by Shen and colleagues provided evidence that the miR-30-CSE-H2S axis contributes to the protection against cardiomyocyte ischemic injury by regulating hydrogen sulfide (H2S) production. Inhibition of the miR-30 family after MI injury offers potential therapeutic value to 'keep our heart going on'...

BACKGROUND: Exposure to ubiquitous polycyclic aromatic hydrocarbons (PAHs) has been associated with decreased heart rate variability (HRV). Evidence accumulates that microRNAs (miRNAs) might be the intermediate factors between environmental exposures and their adverse health effects. Single nucleotide polymorphisms (SNPs) in miRNA genes may affect phenotypes and disease morbidity. OBJECTIVE: We sought to investigate the influences of four well-studied SNPs in miRNA genes (rs2910164, rs11614913, rs2292832, and rs3746444) on HRV, and their modifying effects on the associations between PAH exposure and HRV...

Heart failure (HF) imposes significant economic and public health burdens upon modern society. It is known that disturbances in neurohormonal status play an important role in the pathogenesis of HF. Therapeutics that antagonize selected neurohormonal pathways, specifically the renin-angiotensin-aldosterone and sympathetic nervous systems, have significantly improved patient outcomes in HF. Nevertheless, mortality remains high with about 50% of HF patients dying within five years of diagnosis thus mandating ongoing efforts to improve HF management...

Diabetic cardiomyopathy is a common complication in patients with diabetes and is associated with underlying chronic inflammation and cardiac cell death, subsequently leading to heart failure (HF). ELAV-like protein 1 (ELAVL1) plays a critical role in the progression of inflammation and HF. However the role of ELAVL-1 in inflammation induced cardiac cell death (pyroptosis) under hyperglycemic condition remains elusive. Our data demonstrates that ELAVL1 expression augmented with a concomitant increase in caspase-1 and IL-1 beta expression in human hearts and human ventricular cardiomyocytes under hyperglycemic condition...

BACKGROUND: Hepatocellular carcinoma (HCC) is the most common malignant tumor of the liver. Non-alcoholic fatty liver disease (NAFLD) is a frequent chronic liver disorder in developed countries. NAFLD can progress through the more severe non alcoholic steatohepatitis (NASH), cirrhosis and, lastly, HCC. Genetic and epigenetic alterations of coding genes as well as deregulation of microRNAs (miRNAs) activity play a role in HCC development. In this study, the C57BL/6J mouse model was long term high-fat (HF) or low-fat (LF) diet fed, in order to analyze molecular mechanisms responsible for the hepatic damage progression...

Recent studies have revealed the involvement of microRNAs (miRNAs) in the control of cardiac hypertrophy and myocardial function. In addition, several reports have demonstrated that high fat (HF) diet induces cardiac hypertrophy and remodeling. In the current study, we investigated the effect of diets containing different percentages of fat on the cardiac miRNA expression signature. To address this question, male C57Bl/6 mice were fed with a low fat (LF) diet or two HF diets, containing 45 kcal% fat (HF45%) and 60 kcal% fat (HF60%) for 10 and 20 weeks...

Exercise training (ET) has beneficial effects on the myocardium in heart failure (HF) patients and in animal models of induced cardiac hypertrophy and failure. We hypothesized that if microRNAs (miRNAs) respond to changes following cardiac stress, then myocardial profiling of these miRNAs may reveal cardio-protective mechanisms of aerobic ET in HF. We used ascending aortic stenosis (AS) inducing HF in Wistar rats. Controls were sham-operated animals. At 18 wk after surgery, rats with cardiac dysfunction were randomized to 10 wk of aerobic ET (HF-ET) or to a heart failure sedentary group (HF-S)...
