RORα is a member of nuclear receptor superfamily of transcription factors which has a vital role in the regulation of various physiological processes. Cholesterol is a known ligand of RORα and is one of the key components that take part in cardiovascular diseases such as atherosclerosis. Therefore, it is possible that RORα might have a role in the development of atherosclerosis. To test this hypothesis, we investigated the presence of novel RORα response elements (ROREs) located in the promoter of CYP19A1, MIF and ABCA1 genes...

Numerous studies have examined the role of microRNAs (miRNAs) in cell homeostasis and cardiovascular disease and have markedly improved our understanding of RNA biology in general and the potential role of miRNAs in atherosclerosis. In atherosclerosis, several miRNAs, such as miR-33a,b, miR-92a, miR-126 and others, have been identified that are relevant mediators of pathological processes, including regulation of cholesterol and lipid biosynthesis, lipoprotein metabolism and cholesterol efflux, but also immune responses, endothelial cell biology and vascular function...

The diabetic diet is one of the pillars of diabetes treatment. The rapid development of knowledge relating to the treatment of diabetes also includes diet. The paper focuses on the importance of a diet in the treatment of type 2 diabetes and prevention of atherosclerosis. Its main goal is to assess the impact of a composition of macronutrients on individuals with type 2 diabetes. The paper is divided into several parts, each of which ends with a conclusion. The first part examines weight reduction. The diet aimed at a weight loss is effective, it can effectively prevent diabetes, it leads to improvements in glucose control and reduction of the risk factors for atherosclerosis, however it will not impact on cardiovascular morbidity and mortality until after more than 20 years...

Hyperuricemia is strongly linked to cardiovascular complications including atherosclerosis and thrombosis. In individuals with hyperuricemia, needle-shaped monosodium urate crystals (nsMSU) frequently form within joints or urine, giving rise to gouty arthritis or renal calculi, respectively. These nsMSU are potent instigators of neutrophil extracellular trap (NET) formation. Little is known on the mechanism(s) that prevent nsMSU formation within hyperuricemic blood, which would potentially cause detrimental consequences for the host...

Atherosclerosis, a known and prevalent disease, causes progressive deterioration of affected vessels, inducing a blood flow reduction with different complications, and its symptoms usually manifest in advanced stages of the disease. Therefore, the classic therapeutic alternatives are insufficient because the damages are many times irreversible. For this reason, there is a need to implement intelligent forms of drug administration and develop new therapeutic targets that reduce the progression of atherosclerotic lesion...

OBJECTIVE: Abdominal aortic aneurysm (AAA) is a life-threatening vascular pathology, the pathogenesis of which is closely related to oxidative stress. However, an effective pharmaceutical treatment is lacking because the exact cause of AAA remains unknown. Here, we aimed at delineating the role of the paraoxonases (PONs) gene cluster (PC), which prevents atherosclerosis through the detoxification of oxidized substrates, in AAA formation. APPROACH AND RESULTS: PC transgenic (Tg) mice were crossed to an Apoe(-/-) background, and an angiotensin II-induced AAA mouse model was used to analyze the effect of the PC on AAA formation...

Patients undergoing coronary angiography for suspected coronary heart disease who are found to have coronary atherosclerotic disease with <50% diameter stenosis may carry a risk of adverse cardiac events similar to that in patients with single-vessel obstructive disease. Yet clinical practice guidelines offer no direction for managing symptomatic patients with nonobstructive coronary atherosclerosis because current diagnostic criteria for coronary heart disease are not met. Accordingly, secondary preventive measures are not endorsed, and their role is not defined in this setting...

Atherosclerosis is a chronic inflammatory disease with complex pathological processes. MicroRNA-33 (miR-33), a novel non-coding RNA that coexpresses with sterol regulatory element-binding proteins (SREBPs), affects macrophage actions to prevent atherosclerosis. Fibroblast growth factor 21 (FGF21) is an important regulator of lipid metabolism, especially for macrophage-related cholesterol export, but the mechanism is not fully studied. Interestingly, FGF21 has been evidenced to prevent atherosclerosis via inhibiting SREBP-2 expression...

Atherosclerosis begins in early life and has a long latent period prior to onset of clinical disease. Measures of subclinical atherosclerosis, therefore, may have important implications for research and clinical practice of atherosclerotic cardiovascular disease (ASCVD). In this review, we focus on coronary artery calcium (CAC) and carotid artery intima-media thickness (cIMT) and plaque as many population-based studies have investigated these measures due to their non-invasive features and ease of administration...

RATIONALE: Deficiency of secreted IgM (sIgM(-/-)) accelerates atherosclerosis in Ldlr(-/-) mice. Several atheroprotective effects of increased levels of IgM antibodies have been suggested, including preventing inflammation induced by oxidized LDL and promoting apoptotic cell clearance. However, the mechanisms by which the lack of sIgM promotes lesion formation remain unknown. OBJECTIVE: To identify the mechanisms by which sIgM deficiency accelerates atherosclerosis in mice...

Vascular inflammation is a key factor in the pathogenesis of atherosclerosis. The purpose of this study was to investigate the protective effects of sargachromenol (SCM) against tumor necrosis factor (TNF)-α-induced vascular inflammation. SCM decreased the expression of cell adhesion molecules, including intracellular adhesion molecule-1 and vascular cell adhesion molecule-1, in TNF-α-stimulated human umbilical vein endothelial cells (HUVECs), resulted in reduced adhesion of monocytes to HUVECs. SCM also decreased the production of monocyte chemoattractant protein-1 and matrix metalloproteinase-9 in TNF-α-induced HUVECs...

The ankle-brachial index (ABI) is a marker of subclinical atherosclerosis related to health-adverse outcomes. ABI is inexpensive compared to other indexes, such as coronary calcium score and determination of carotid artery intima-media thickness (IMT). Our objective was to identify how the ABI can be applied to primary care. Three different methods of calculating the ABI were compared among 13,921 men and women aged 35 to 74 years who were free of cardiovascular diseases and enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)...

Understanding of the pathophysiological mechanisms is the cornerstone of preventive and treatment strategies in the battle against coronary artery disease. Hyperlipidemia, arterial hypertension, smoking and diabetes, are established risk factors affecting coronary vasculature. However, the focal formation of atherosclerotic lesions in certain arterial regions underscores that local factors are implicated in the initiation and progression of atherosclerosis. Introduction of novel imaging modalities and technological advances offered new insights and acknowledged intravascular hemodynamics, and particularly flow-derived endothelial shear stress as a critical factor in the natural history of coronary artery disease...
