Human low-density lipoprotein (LDL) is a highly complex nano-particle built up of various lipid classes and a single large protein moiety (apoB-100) owning essential physiological functions in the human body. Besides its vital role as a supplier of cholesterol and fat for peripheral tissues and cells, it is also a known key player in the formation of atherosclerosis. Due to these important roles in physiology and pathology the elucidation of structural and dynamical details is of great interest. In the current study we drew a broader picture of LDL dynamics using elastic incoherent neutron scattering (EINS) as a function of specified temperature and pressure points...

Dyslipidemia is caused by disturbances in lipid metabolism that lead to chronic elevations of serum lipids, especially low-density lipoprotein (LDL)-cholesterol and triglycerides, increasing the risk of metabolic syndrome, obesity, diabetes, atherogenic processes, and cardiovascular diseases. The oil from the fruits of Euterpe oleracea (OFEO) is rich in unsaturated fatty acids with potential for treating alterations in lipid metabolism. In this study, we aimed to investigate the effect of OFEO on hyperlipidemia induced by Cocos nucifera L...

Our previous studies demonstrated that the first 1000 amino acid residues (the βα1 domain) of human apolipoprotein (apo) B-100, referred to as apoB:1000, are required for the initiation of lipoprotein assembly and the formation of a monodisperse stable phospholipid (PL)-rich particle. The objectives of this study were to: a) assess the effects on the properties of apoB truncates undergoing sequential inclusion of the amphipathic β strands in the N-terminal 700 residues of the β1 domain of apoB-100, and b) identify the subdomain in the β1 domain that is required for the formation of a microsomal triglyceride transfer protein (MTP)-dependent triacylglycerol (TAG)-rich apoB-containing particle...

Apolipoprotein C3 (APOC3) is produced mainly by the liver and intestine and approximately half of plasma APOC3 associates with HDL. Though it was believed that APOC3 associates with HDL by simple binding to pre-existing particles, recent data support that biogenesis of APOC3-containing HDL (APOC3-HDL) requires Abca1. Moreover, APOC3-HDL contributes to plasma triglyceride homeostasis, by preventing APOC3 association with triglyceride-rich lipoproteins. Interestingly, APOC3-HDL also shows positive correlation with the morbidly obese phenotype...

Apolipoprotein C-III (apoC-III) is often assumed to retard the intravascular processing of triglyceride-rich lipoproteins (TRLs) by inhibiting lipoprotein lipase (LPL), but that view is based largely on studies of free LPL. We now recognize that intravascular LPL is neither free nor loosely bound but instead is tightly bound to GPIHBP1 on endothelial cells. Here, we revisited the effects of apoC-III on LPL, focusing on apoC-III's capacity to affect the activity of GPIHBP1-bound LPL. We found that TRLs from APOC3 transgenic mice bound normally to GPIHBP1-bound LPL on cultured cells in vitro and to heart capillaries in vivo...

BACKGROUND: We hypothesized that an increase in plasminogen activator inhibitor 1 (PAI-1) might reduce low-density lipoprotein (LDL) particle size in conjunction with triglyceride (TG) metabolism disorder, resulting in an increased risk of atherosclerotic cardiovascular disease (ASCVD). METHODS: This study was carried out as a hospital-based cross-sectional study in 537 consecutive outpatients (mean age: 64 years; men: 71%) with one or more risk factors for ASCVD from April 2014 to October 2014 at the Cardiovascular Center of Nihon University Surugadai Hospital...

BACKGROUND: The interactions between inflammation and lipid profile in rheumatoid arthritis (RA) are poorly understood. The lipid profile study in RA has been biased toward lipoprotein levels, whereas those of triglycerides (TGs) and lipoprotein functionality have been underestimated. OBJECTIVES: Since recent findings suggest a role for TG and TG-rich lipoproteins (TRL) on inflammation, we aimed to evaluate a combined lipid profile characterized by high TG and low high-density lipoprotein cholesterol levels (TG(high)HDL(low)) in RA...

BACKGROUND: We investigated the relationship between the eicosapentaenoic acid (EPA)/arachidonic acid (AA) ratio and non-high-density lipoprotein cholesterol (non-HDL-C) level, a major residual risk of coronary artery disease (CAD), in statin-treated CAD patients following EPA therapy. METHODS: We conducted a 6-month, prospective, randomized clinical trial to investigate the effect of the additional administration of EPA on the EPA/AA ratio and the serum non-HDL-C level in stable CAD patients receiving statin treatment...

BACKGROUND: Cold exposure and β3-adrenergic receptor agonism, which both activate brown adipose tissue, markedly influence lipoprotein metabolism by enhancing lipoprotein lipase-mediated catabolism of triglyceride-rich lipoproteins and increasing plasma high-density lipoprotein (HDL) levels and functionality in mice. However, the effect of short-term cooling on human lipid and lipoprotein metabolism remained largely elusive. OBJECTIVE: The objective was to assess the effect of short-term cooling on the serum lipoprotein profile and HDL functionality in men...

BACKGROUND: Mitral annular calcium (MAC), commonly identified by cardiac imaging, is associated with cardiovascular events and predisposes to the development of clinically important mitral valve regurgitation and mitral valve stenosis. However, its biological determinants remain largely unknown. OBJECTIVES: The authors sought to evaluate whether a genetic predisposition to elevations in plasma lipids is associated with the presence of MAC. METHODS: The authors used 3 separate Mendelian randomization techniques to evaluate the associations of lipid genetic risk scores (GRS) with MAC in 3 large patient cohorts: the Framingham Health Study, MESA (Multiethnic European Study of Atherosclerosis), and the AGE-RS (Age, Gene/Environment Susceptibility-Reykjavik Study)...

Hypertriglyceridemia (HTG) is an independent factor of atherosclerotic cardiovascular disease and a hallmark of many metabolic disorders. However, the molecular etiology of HTG is still largely unknown. In mice, severe HTG may be induced by expression of specific mutants of apolipoprotein (apo) A-I or wild type (WT) apoE4. Expression of a certain apoE4 mutant results in mild HTG, while expression of another apoE4 mutant or WT apoA-I results in normal plasma triglyceride (TG) levels. Biophysical studies of the apoA-I and apoE4 forms associated with HTG help better understand the molecular mechanisms of induction of HTG by these proteins...

Elevated triglyceride levels (higher than ~1000 mg/dL) are associated with an increased risk for pancreatitis. Apolipoprotein-CIII (apoC-III) plays a key role in the metabolism of triglycerides and triglyceride-rich lipoproteins. Loss of function mutations in the gene encoding apoC-III (APOC3) are associated with low triglyceride levels and a decreased risk for cardiovascular disease (CVD) while overexpression of APOC3 is associated with hypertriglyceridemia. Although many drugs such as fibrates, statins and omega-3 fatty acids modestly decrease triglyceride levels (and apoC-III concentrations), there are many patients who still have severe hypertriglyceridemia and are at increased risk for pancreatitis and potentially for CVD...

OBJECTIVE: A high plasma level of remnant-like particle cholesterol (RLP-C), which is equivalent to triglyceride-rich lipoprotein remnant, is an important coronary risk marker. RLP-C level is high, independent of other plasma lipids, in patients with chronic kidney disease (CKD) undergoing hemodialysis. The effect of teneligliptin, a dipeptidyl peptidase (DPP)-4 inhibitor, on plasma levels of RLP-C in patients with diabetes mellitus and CKD under hemodialysis was studied. METHODS: Teneligliptin 20 mg/day was administered to 15 patients with diabetes and CKD undergoing hemodialysis for 12 weeks...

Lipoprotein lipase (LPL) catalyzes the hydrolysis of triglycerides from triglyceride-rich lipoproteins such as VLDL and chylomicrons in the circulation. Mutations in LPL or its activator apolipoprotein C-II cause hypertriglyceridemia in humans and animal models. The levels of LPL in the liver are low but they can be strongly induced by a high cholesterol diet or by synthetic ligands of Liver X Receptors (LXRs). However, the mechanism by which LXRs activate the human LPL gene is unknown. In the present study we show that LXR agonists increased the mRNA and protein levels as well as the promoter activity of human LPL in HepG2 cells...

ApoE3 is the major chylomicron apolipoprotein, binding in a specific liver peripheral cell receptor, allowing transport and normal catabolism of triglyceride-rich lipoprotein constituents. Point mutations in ApoE3 have been associated with Alzheimer's disease, type III hyperlipoproteinemia, atherosclerosis, telomere shortening and impaired cognitive function. Here, we evaluate the impact of missense SNPs in APOE retrieved from dbSNP through 16 computational prediction tools, and further evaluate the structural impact of convergent deleterious changes using 100 ns molecular dynamics simulations...

Congenital disorders of lipid metabolism are caused by a wide range of variants of the genes for receptors, apolipoproteins, enzymes, transfer factors, and cellular cholesterol transporters. Clinically most relevant are autosomal dominant familial hypercholesterolemia (FH) and familial combined hyperlipoproteinemia (FCHL). FH has a prevalence of 1:250. It is due to mutations of the low density lipoprotein (LDL) receptor, less often to mutations of the apolipoprotein B (APOB), the proprotein convertase subtilisin/kexin type 9 (PCSK9), or the signal transducing adapter family member 1 (STAP1)...

PURPOSE OF REVIEW: This study aimed to present the current information on the genetic background of dyslipidemias and provide insights into the complex pathophysiological role of several plasma lipids/lipoproteins in the pathogenesis of atherosclerotic cardiovascular disease. Furthermore, we aim to summarize established therapies and describe the scientific rationale for the development of novel therapeutic strategies. RECENT FINDINGS: Evidence from genetic studies suggests that besides lowering low-density lipoprotein cholesterol, pharmacological reduction of triglyceride-rich lipoproteins, or lipoprotein(a) will reduce risk for coronary heart disease...

Background: Asymmetric α-carotene, a provitamin A carotenoid, is cleaved to produce retinol (vitamin A) and α-retinol (with negligible vitamin A activity). The vitamin A activity of α-carotene-containing foods is likely overestimated because traditional analytic methods do not separate α-retinol derivatives from active retinol.Objective: This study aimed to accurately characterize intestinal α-carotene cleavage and its relative contribution to postprandial vitamin A in humans after consumption of raw carrots...

BACKGROUND: Elevated apolipoprotein C-III (apoC-III) has been postulated to contribute to the atherogenic dyslipidemia seen in obesity and insulin-resistant states, mainly by impairing plasma triglyceride-rich lipoprotein (TRL) metabolism. Bariatric surgery is associated with improvements of several obesity-associated metabolic abnormalities, including a reduction in plasma triglycerides (TGs) and an increase in plasma high-density lipoprotein cholesterol (HDL-C). OBJECTIVES: We investigated the specific effect of bariatric surgery on apoC-III concentrations in plasma, non-HDL, and HDL fractions in relation to lipid profile parameters evolution...

AbstractThe serum lipid profile in malaria patients has been found to differ from that of healthy controls. We investigated serum lipid profile changes in malaria patients over time compared with patients with other febrile diseases. In total, 217 patients were included in the study (111 malaria patients and 106 symptomatic controls, defined as malaria-negative febrile patients). Serum lipid levels (mmol/L) were significantly lower in malaria patients compared with those with other febrile diseases (total cholesterol [TC] = 3...
