BACKGROUND AND AIMS: Peripheral insulin resistance is associated with several metabolic abnormalities, including elevated serum fatty acids that contribute to vascular injury and atherogenesis. Our goals were to examine whether saturated fatty acids can modify innate immune responses to subclinical concentrations of lipopolysaccharide (LPS) in endothelial cells, and to explore the underlying pathway and determine whether it is modified by high density lipoprotein (HDL) and other factors commonly altered in insulin resistance...

Atherogenesis is the process of atherosclerotic plaque formation, leading to coronary artery heart disease. This process involves immune cells, mainly T and B cells, monocytes and macrophages. The process of atherogenesis is induced by inflammatory damage of endothelial cells. The characteristic construction features of the atherosclerotic plaque is a predisposing factor for acute coronary syndromes. The accumulation of inflammatory cells in the artery inner membrane enhances the local inflammatory process due to the secretion of reactive oxygen species, inflammatory cytokines and metalloproteinases, which accelerate the development of atherosclerotic lesions in the arteries...

Cardiovascular safety is an important consideration in the debate on the benefits versus the risks of electronic cigarette (EC) use. EC emissions that might have adverse effects on cardiovascular health include nicotine, oxidants, aldehydes, particulates, and flavourants. To date, most of the cardiovascular effects of ECs demonstrated in humans are consistent with the known effects of nicotine. Pharmacological and toxicological studies support the biological plausibility that nicotine contributes to acute cardiovascular events and accelerated atherogenesis...

Miao Zhang, Huaiping Zhu, Ye Ding, Zhaoyu Liu, Zhejun Cai, Ming-Hui Zou
Monocyte-to-macrophage differentiation, which can be initiated by physiological or atherogenic factors, is a pivotal process in atherogenesis, a disorder in which monocytes adhere to endothelial cells and subsequently migrate into the sub-endothelial spaces, where they differentiate into macrophages and macrophage-derived foam cells and cause atherosclerotic lesions. However, the monocyte-differentiation signaling pathways that are activated by atherogenic factors are poorly defined. Here we report that the AMP- activated protein kinase (AMPK) α1 in monocytes promotes atherosclerosis by increasing monocyte differentiation and survival...

We investigated IL-1-induced regulation of genes related to inflammation and atherogenesis in human keratinocytes and endothelial cells, and if 'diacerein', an oral IL-1 inhibiting drug currently approved for use in osteoarthritis, would reverse IL-1's effects on these cells. Primary human keratinocytes and coronary artery endothelial cells were treated with either IL-1α or IL-1β, with and without diacerein. Using PCR-array, we assessed differential gene-expression regulated by IL-1 and diacerein. We identified 34 pro-atherogenic genes in endothelial cells and 68 pro-inflammatory genes in keratinocytes significantly (p<0...

Oxidized low-density lipoprotein (oxLDL) plays a central role in the pathogenesis of atherosclerosis, in part via an effect to promote endothelial dysfunction. In the present study, we evaluated the expression profiles of long non-coding RNAs (lncRNAs) and protein-coding mRNAs in endothelial cells following oxLDL stimulation. LncRNAs and mRNAs from human umbilical vein endothelial cells (HUVECs) were profiled with the Arraystar Human lncRNA Expression Microarray V3.0 following 24 h of oxLDL treatment (100 µg/mL)...

Phosphatidylcholine (PC)-specific phospholipase C (PC-PLC) hydrolyzes PC to generate the second messenger 1,2-diacylglycerol (DG) and phosphocholine. PC-PLC plays pivotal roles in inflammation, carcinogenesis, tumor progression, atherogenesis, and subarachnoid hemorrhage. Although the activity of PC-PLC in mammalian tissues was discovered approximately 40 years ago, neither the protein nor its gene has been identified. In the present study, we developed a non-radioactive enzyme activity assay for PC-PLC based on mass spectrometric detection of DG following HPLC separation...

BACKGROUND: The prevalence of premature atherosclerosis and cardiovascular disease (CVD) is constantly increasing worldwide. It has been proved that LDL-cholesterol (LDL-C) plays causal role in the development of coronary atherosclerosis. The fact that atherosclerosis is a chronic and progressive disease which onsets during the first three decades of life bores questions what to do to maintain LDL-C at low levels throughout life and thus to delay and/or prevent the progress this disease...

Constitutive photomorphogenesis 9 (COP9) signalosome 5 (CSN5), an isopeptidase that removes neural precursor cell-expressed, developmentally down-regulated 8 (NEDD8) moieties from cullins (thus termed "deNEDDylase") and a subunit of the cullin-RING E3 ligase-regulating COP9 signalosome complex, attenuates proinflammatory NF-κB signaling. We previously showed that CSN5 is up-regulated in human atherosclerotic arteries. Here, we investigated the role of CSN5 in atherogenesis in vivo by using mice with myeloid-specific Csn5 deletion...

Atherosclerosis is a vascular pathology characterized by inflammation and plaque build-up within arterial vessel walls. Vessel occlusion, often occurring after plaque rupture, can result in myocardial and cerebral infarction. Epigenetic changes are increasingly being associated with atherosclerosis and are of interest from both therapeutic and biomarker perspectives. Emerging genomic approaches that profile DNA methylation, chromatin accessibility, post-translational histone modifications, transcription factor binding, and RNA expression in low or single cell populations are poised to enhance our spatiotemporal understanding of atherogenesis...

Obstructive sleep apnea syndrome (OSA) is associated with increased vascular morbidity. Accelerated atherosclerosis might be one of the most important mechanisms linking OSA with the development of vascular disorders. Homocysteine (HCY) and vitamin D has been associated with atherogenesis. The aim of this study was to assess a possible association between the levels of HCY and vitamin D and the carotid intima-media thickness (cIMT), which is a known marker for subclinical atherosclerosis in patients with OSA...

BACKGROUND: There is strong evidence indicating that gut microbiota have the potential to modify, or be modified by the drugs and nutritional interventions that we rely upon. This study aims to characterize the compositional and functional effects of several nutritional, neutraceutical, and pharmaceutical cardiovascular disease interventions on the gut microbiome, through metagenomic and metabolomic approaches. Apolipoprotein-E-deficient mice were fed for 24 weeks either high-fat/cholesterol diet alone (control, HFC) or high-fat/cholesterol in conjunction with one of three dietary interventions, as follows: plant sterol ester (PSE), oat β-glucan (OBG) and bile salt hydrolase-active Lactobacillus reuteri APC 2587 (BSH), or the drug atorvastatin (STAT)...

BACKGROUND AND AIMS: Galectin 3 (Gal 3) is a β-galactoside-binding lectin known to play a part in inflammation, adverse remodeling and fibrosis. Gal 3 seems to be linked to atherogenesis and Coronary Artery Disease (CAD), but less is known about the relationship between Gal 3 and acute myocardial infarction (AMI). The aim of the present study is to assess circulating levels of Gal 3 after AMI and to evaluate short-term changes of the biomarker within 5 days from the acute event. METHODS: Two hundred fifteen confirmed AMI patients (125 STEMI, M/F = 2...

Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) is a serine protease involved in cholesterol homeostasis. After binding to the complex low-density lipoprotein (LDL)-receptor, PCSK9 induces its intracellular degradation, thus reducing serum LDL clearance. PCSK9 is mainly secreted by the liver, but it is also expressed to a lesser extent in other organs. Apart from the well-known activity concerning hepatic LDL receptor-mediated pathway, PCSK9 has been supposed to potentially interfere with vascular inflammation in atherogenesis...

Oncostatin M (OSM) is a secreted cytokine mainly involved in chronic inflammatory and cardiovascular diseases through binding to OSM receptor β(OSMR-β). Recent studies demonstrated that the presence of OSM contributed to the destabilization of atherosclerotic plaque. To investigate whether OSMR-β deficiency affects atherosclerosis, male OSMR-β-/-ApoE-/- mice were generated and utilized. Here we observed OSMR-β expression was remarkably up-regulated in both human and mouse atherosclerotic lesions, which was mainly located in macrophages...

Inflammation is known to play a significant role in the process of atherogenesis and cardiovascular disease (CVD). Indeed, patients with chronic inflammatory diseases are at increased risk for cardiovascular events. The mechanisms linking chronic inflammation and CVD however remain poorly understood. Psoriasis, a chronic inflammatory skin disease associated with a greater risk of early cardiovascular events, provides a suitable human model to study the pathophysiology of inflammatory atherogenesis in humans...

The transformation of vascular smooth muscle cells [VSMC] into foam cells leading to increased plaque size and decreased stability is a key, yet understudied step in atherogenesis. We reported that Interleukin-19 (IL-19), a novel, anti-inflammatory cytokine, attenuates atherosclerosis by anti-inflammatory effects on VSMC. In this work we report that IL-19 induces expression of miR133a, a muscle-specific miRNA, in VSMC. Although previously unreported, we report that miR133a can target and reduce mRNA abundance, mRNA stability, and protein expression of Low Density Lipoprotein Receptor Adaptor Protein 1, (LDLRAP1), an adaptor protein which functions to internalize the LDL receptor...
