PURPOSE OF REVIEW: This review summarizes the evidence supporting a relationship between lowering triglycerides (TGs) and TG-rich lipoprotein cholesterol (TGRL-C) levels and reduced atherosclerotic cardiovascular disease (ASCVD) event risk. RECENT FINDINGS: Data from observational investigations, including studies of genetic variants, provide evidence consistent with a causal relationship between elevations in TG and TGRL-C and greater risk for ASCVD. Randomized controlled trial evidence of ASCVD risk reduction with therapies that substantially lower TG and TGRL-C is limited by the fact that no large-scale trial results have been published from a study that enrolled subjects selected specifically on the basis of TG or TGRL-C elevation, although three such trials are underway or in the planning stages...

Extreme hypertriglyceridemia is rare in the neonatal period. We report a neonate with lipoprotein lipase (LPL) deficiency who presented with diagnostic and management conundrum. A full-term 36-day-old female was noted to have "Pepto-Bismol like" blood when repeating a newborn screening. The initial plasma triglyceride level was 24,318 mg/dL. The laboratory tests revealed serum bicarbonate level of <5 mmol/L, sodium of 127 mmol/L, and severe anemia. There were no signs of acute distress. The point of care capillary blood testing, however, demonstrated normal serum pH (7...

Atherosclerosis-related research has focused mainly on the effects of lipids on macrophage foam cell formation and atherogenesis, whereas the role of amino acids (AAs) was understudied. The current study aimed to identify anti- or pro-atherogenic AA in the macrophage model system and to elucidate the underlying metabolic and molecular mechanisms. J774A.1 cultured macrophages were treated with increasing concentrations of each 1 of the 20 AAs. Macrophage atherogenicity was assessed in terms of cellular toxicity, generation of reactive oxygen species (ROS) and cellular cholesterol or triglyceride content...

BACKGROUND AND OBJECTIVES: Arterial stiffness is a leading cause of cardiovascular disease (CVD), and it is considered to be affected by dietary intake. However, few studies have examined the relationship between major dietary patterns and brachial-ankle pulse wave velocity (baPWV) among Japanese middle-aged subjects. We studied whether major dietary patterns were associated with baPWV in this population. METHODS AND STUDY DESIGN: Between 2009 and 2012, 70 Japanese middle-aged subjects (39 men and 31 women) with no history of stroke, coronary heart disease, or cancer were studied...

Very low-density lipoprotein (VLDL) receptor is a member of the low-density lipoprotein (LDL) receptor family. It binds triglyceride rich lipoprotein (TGRL) but not LDL, because it recognizes apolipoprotein (apo)E only but not apoB. The VLDL receptor functions as a peripheral lipoprotein receptor in concert with lipoprotein lipase (LPL) in heart, muscle, adipose tissue and macrophages. In contrast to the LDL receptor, VLDL receptor binds apo E2/2 VLDL and apoE3/3 VLDL particles, and its expression is not down-regulated by intracellular lipoproteins...

Backgound: Recent findings indicate that incretin hormones and incretin-based therapies may affect the metabolism of lipoproteins, although the corresponding mechanisms are not clearly defined. OBJECTIVE: To summarize the available data on the mechanisms linking incretins with the characteristics of serum lipoproteins and discuss the clinical implications of these relationships. METHODS: PubMed was searched using the terms "incretins", "GLP-1", "GIP" and "lipids", "dyslipidemia", "triglycerides", "apolipoprotein B48"...

ANGPTL4 regulates plasma triglyceride levels by inhibiting lipoprotein lipase. Inactivation of ANGPTL4 decreases plasma triglycerides and reduces risk of coronary artery disease. Unfortunately, targeting ANGPTL4 for the therapeutic management of dyslipidemia and atherosclerosis is hampered by the observation that mice and monkeys in which ANGPTL4 is inactivated exhibit lipid accumulation in mesenteric lymph nodes. In mice these pathological events exclusively unfold upon feeding a high saturated fatty acid diet and are followed by an ultimately lethal pro-inflammatory response and chylous ascites...

OBJECTIVES: Dyslipidemias are defined as changes in lipid metabolism that have abnormal concentrations of lipids or lipoproteins in the bloodstream. Chronic increase in triglyceride and low-density lipoprotein (LDL-c) levels are known as risk factors for the atherogenesis process as well as other cardiovascular diseases (CVDs). The magnitude of the problems caused by dyslipidemias impels research by new agents that act in the prevention and control. Thus, products from the Amazonian biodiversity, such as Euterpe oleracea oil (OFEO), rich in unsaturated fatty acids (UFAs), constitutes a study source for the treatment of alterations in lipid metabolism...

BACKGROUND: A protein that is expressed on capillary endothelial cells, called GPIHBP1 (glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1), binds lipoprotein lipase and shuttles it to its site of action in the capillary lumen. A deficiency in GPIHBP1 prevents lipoprotein lipase from reaching the capillary lumen. Patients with GPIHBP1 deficiency have low plasma levels of lipoprotein lipase, impaired intravascular hydrolysis of triglycerides, and severe hypertriglyceridemia (chylomicronemia)...

BACKGROUND: Lipoprotein lipase (LPL) is one of the major enzymes responsible for the hydrolysis of triglyceride (TG)-rich lipoprotein. The effects of LPL polymorphisms on serum TG are inconsistent among different populations. OBJECTIVES: This study aims to assess the TG serum concentration and distributions of three LPL single nucleotide polymorphisms (SNPs), namely D9N, HINDIII and S447X, in a nationally representative sample of Iranian adolescents. MATERIAL AND METHODS: We studied the associations between SNP genotypes and TG levels in a nationally representative sample of Iranian adolescents...

Clinicians are well aware of the importance of a positive family history for coronary artery disease (CAD). Nonetheless, elucidation of the genetic basis of CAD has long proven difficult. The scenario changed in the last decade through the application of modern genomic technologies, like genome-wide association studies (GWAS) and next generation sequencing (NGS). GWAS have discovered over 60 common variants highly associated with CAD. For predictive purposes, such variants have been used to build up Genetic Risk Scores (GRSs), but their incorporation into classical prediction models does not appear substantially outperform the simple addition of family history...

Small dense LDL (sdLDL) has been reported to be more atherogenic than large buoyant LDL (lbLDL). We examined the metabolism and protein composition of sdLDL and lbLDL in six subjects with combined hyperlipidemia on placebo and rosuvastatin 40 mg/day. ApoB-100 kinetics in triglyceride rich lipoproteins (TRL), lbLDL (density [d] 1.019-1.044 g/ml), and sdLDL (d 1.044-1.063 g/ml) were determined in the fed state using stable isotope tracers, mass spectrometry, and compartmental modeling. Compared with placebo, rosuvastatin decreased LDL cholesterol and apoB-100 levels in TRL, lbLDL, and sdLDL by significantly increasing the fractional catabolic rate of apoB-100 (TRL +45%; lbLDL +131%; sdLDL +97%), without a change in production...

BACKGROUND: Elevated plasma apoB is an independent predictor of T2D; however, underlying mechanisms remain unclear. Chronic reduction in white adipose tissue (WAT) function promotes T2D. We reported that differentiation of preadipocytes and acute incubation of human WAT with LDL induce their dysfunction (decreased hydrolysis and storage of triglyceride-rich lipoproteins [TRL]). OBJECTIVE: To examine the hypothesis that the association of plasma apoB with T2D risk factors, hypertriglyceridemia (hyperTG), insulin resistance (IR), and hyperinsulinemia, was dependent on WAT dysfunction...

BACKGROUND: Severe hypertriglyceridemia (HTG) may result from mutations in genes affecting the intravascular lipolysis of triglyceride (TG)-rich lipoproteins. OBJECTIVE: The aim of this study was to develop a targeted next-generation sequencing panel for the molecular diagnosis of disorders characterized by severe HTG. METHODS: We developed a targeted customized panel for next-generation sequencing Ion Torrent Personal Genome Machine to capture the coding exons and intron/exon boundaries of 18 genes affecting the main pathways of TG synthesis and metabolism...

Grape pomace (GP), the residue of grapes after wine making, is rich in dietary polyphenols and fiber, and it has potential to serve as a functional food ingredient to improve health. However, high polyphenol diets have also been reported to inhibit the growth of young animals and cause liver necrosis. This study investigated the effect of diets containing different amounts of GP on the growth performance and blood lipid profile by using a young rat model. Twenty female Sprague-Dawley rats of age 7 weeks were randomly divided into four groups that were fed AIN-93G diets that were modified by substituting 0%, 10%, 20%, and 30% of carbohydrate with GP for 10 weeks (the diets, thus, obtained contained 0%, 6...

Lipid composition of human low-density lipoprotein (LDL) and its physicochemical characteristics are relevant for proper functioning of lipid transport in the blood circulation. To explore dynamical and structural features of LDL particles with either a normal or a triglyceride-rich lipid composition we combined coherent and incoherent neutron scattering methods. The investigations were carried out under high hydrostatic pressure (HHP), which is a versatile tool to study the physicochemical behavior of biomolecules in solution at a molecular level...

Cardiovascular disease (CVD) is one of the leading causes of morbidity and mortality worldwide, and dyslipidemia constitutes a major risk factor for CVD and premature atherosclerosis. Therapies to reduce the plasma levels of atherogenic lipoproteins are well established interventions that decrease CVD risk. However, treatment of dyslipidemia with the most widely used lipid-lowering drugs (ie, statins and ezetimibe) often fails to protect a significant proportion of patients from cardiovascular risk. The development of several novel therapies to treat lipid-related disorders and their associated risks is ongoing and includes the following: (1) reducing plasma levels of atherogenic lipoproteins using proprotein convertase subtilisin/kexin type 9 inhibitors, antisense inhibitors of Apolipoprotein (Apo)(a), microsomal triglyceride transfer protein inhibitors, antisense oligonucleotides of ApoB for inhibiting very low-density lipoprotein production, and inhibitors of angiopoietin-like protein 3 or ApoC-III for triglyceride-rich lipoprotein management upstream of low-density lipoprotein production as well as gene replacement therapy to improve low-density lipoprotein and triglyceride-rich lipoprotein clearance; and (2) emerging therapies that target high-density lipoprotein (HDL) and reverse cholesterol transport using cholesteryl ester transfer protein inhibitors, HDL peptide mimetics, and autologous infusion of pre-β HDLs...

Background: The role of plasma apolipoprotein (apo) C-I in cardiometabolic risk in humans is unclear. However, in vitro studies showed a dual role for apoC-I, both protective and harmful, depending on the carrier lipoprotein.Objective: We tested the hypothesis that triglyceride (TG)-rich lipoprotein (TRL) apoC-I, not total or HDL apoC-I, is associated with delayed postprandial plasma clearance of TRLs, independently of apoC-II, apoC-III, and apoE.Methods: This cross-sectional study examines the plasma clearance of a (13)C-triolein-labeled high-fat meal (68% fat energy) in 20 postmenopausal overweight and obese women [body mass index (in kg/m(2)) ≥27; aged 45-74 y] as the increment change in area under the 6-h postprandial curves (iAUC6h) of TRL parameters...
