Apolipoproteins E
A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.
Apolipoproteins C
A group of apolipoproteins that can readily exchange among the various classes of lipoproteins (HDL; VLDL; CHYLOMICRONS). After lipolysis of TRIGLYCERIDES on VLDL and chylomicrons, Apo-C proteins are normally transferred to HDL. The subtypes can modulate remnant binding to receptors, LECITHIN CHOLESTEROL ACYLTRANSFERASE, or LIPOPROTEIN LIPASE.
Apolipoproteins
Protein components on the surface of LIPOPROTEINS. They form a layer surrounding the hydrophobic lipid core. There are several classes of apolipoproteins with each playing a different role in lipid transport and LIPID METABOLISM. These proteins are synthesized mainly in the LIVER and the INTESTINES.
Apolipoprotein C-III
A 9-kDa protein component of VERY-LOW-DENSITY LIPOPROTEINS and CHYLOMICRON REMNANTS. Apo C-III, synthesized in the liver, is an inhibitor of LIPOPROTEIN LIPASE. Apo C-III modulates the binding of chylomicron remnants and VLDL to receptors (RECEPTORS, LDL) thus decreases the uptake of triglyceride-rich particles by the liver cells and subsequent degradation. The normal Apo C-III is glycosylated. There are several polymorphic forms with varying amounts of SIALIC ACID (Apo C-III-0, Apo C-III-1, and Apo C-III-2).
Apolipoprotein E3
A 34-kDa glycosylated protein. A major and most common isoform of apolipoprotein E. Therefore, it is also known as apolipoprotein E (ApoE). In human, Apo E3 is a 299-amino acid protein with a cysteine at the 112 and an arginine at the 158 position. It is involved with the transport of TRIGLYCERIDES; PHOSPHOLIPIDS; CHOLESTEROL; and CHOLESTERYL ESTERS in and out of the cells.
Apolipoproteins A
Structural proteins of the alpha-lipoproteins (HIGH DENSITY LIPOPROTEINS), including APOLIPOPROTEIN A-I and APOLIPOPROTEIN A-II. They can modulate the activity of LECITHIN CHOLESTEROL ACYLTRANSFERASE. These apolipoproteins are low in atherosclerotic patients. They are either absent or present in extremely low plasma concentration in TANGIER DISEASE.
Lipoproteins
Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes.
Apolipoproteins B
Major structural proteins of triacylglycerol-rich LIPOPROTEINS. There are two forms, apolipoprotein B-100 and apolipoprotein B-48, both derived from a single gene. ApoB-100 expressed in the liver is found in low-density lipoproteins (LIPOPROTEINS, LDL; LIPOPROTEINS, VLDL). ApoB-48 expressed in the intestine is found in CHYLOMICRONS. They are important in the biosynthesis, transport, and metabolism of triacylglycerol-rich lipoproteins. Plasma Apo-B levels are high in atherosclerotic patients but non-detectable in ABETALIPOPROTEINEMIA.
Apolipoprotein A-I
The most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. This protein serves as an acceptor for CHOLESTEROL released from cells thus promoting efflux of cholesterol to HDL then to the LIVER for excretion from the body (reverse cholesterol transport). It also acts as a cofactor for LECITHIN CHOLESTEROL ACYLTRANSFERASE that forms CHOLESTEROL ESTERS on the HDL particles. Mutations of this gene APOA1 cause HDL deficiency, such as in FAMILIAL ALPHA LIPOPROTEIN DEFICIENCY DISEASE and in some patients with TANGIER DISEASE.
Apolipoprotein A-II
The second most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. It has a high lipid affinity and is known to displace APOLIPOPROTEIN A-I from HDL particles and generates a stable HDL complex. ApoA-II can modulate the activation of LECITHIN CHOLESTEROL ACYLTRANSFERASE in the presence of APOLIPOPROTEIN A-I, thus affecting HDL metabolism.
Apolipoprotein C-II
A 9-kDa protein component of VERY-LOW-DENSITY LIPOPROTEINS. It contains a cofactor for LIPOPROTEIN LIPASE and activates several triacylglycerol lipases. The association of Apo C-II with plasma CHYLOMICRONS; VLDL, and HIGH-DENSITY LIPOPROTEINS is reversible and changes rapidly as a function of triglyceride metabolism. Clinically, Apo C-II deficiency is similar to lipoprotein lipase deficiency (HYPERLIPOPROTEINEMIA TYPE I) and is therefore called hyperlipoproteinemia type IB.
Lipoproteins, HDL
A class of lipoproteins of small size (4-13 nm) and dense (greater than 1.063 g/ml) particles. HDL lipoproteins, synthesized in the liver without a lipid core, accumulate cholesterol esters from peripheral tissues and transport them to the liver for re-utilization or elimination from the body (the reverse cholesterol transport). Their major protein component is APOLIPOPROTEIN A-I. HDL also shuttle APOLIPOPROTEINS C and APOLIPOPROTEINS E to and from triglyceride-rich lipoproteins during their catabolism. HDL plasma level has been inversely correlated with the risk of cardiovascular diseases.
Apolipoproteins D
A glycoprotein component of HIGH-DENSITY LIPOPROTEINS that transports small hydrophobic ligands including CHOLESTEROL and STEROLS. It occurs in the macromolecular complex with LECITHIN CHOLESTEROL ACYLTRANSFERASE. Apo D is expressed in and secreted from a variety of tissues such as liver, placenta, brain tissue and others.
Apolipoprotein C-I
A 6.6-kDa protein component of VERY-LOW-DENSITY LIPOPROTEINS; INTERMEDIATE-DENSITY LIPOPROTEINS; and HIGH-DENSITY LIPOPROTEINS. Apo C-I displaces APO E from lipoproteins, modulate their binding to receptors (RECEPTORS, LDL), and thereby decrease their clearance from plasma. Elevated Apo C-I levels are associated with HYPERLIPOPROTEINEMIA and ATHEROSCLEROSIS.
Cholesterol
The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.
Lipoproteins, VLDL
A class of lipoproteins of very light (0.93-1.006 g/ml) large size (30-80 nm) particles with a core composed mainly of TRIGLYCERIDES and a surface monolayer of PHOSPHOLIPIDS and CHOLESTEROL into which are imbedded the apolipoproteins B, E, and C. VLDL facilitates the transport of endogenously made triglycerides to extrahepatic tissues. As triglycerides and Apo C are removed, VLDL is converted to INTERMEDIATE-DENSITY LIPOPROTEINS, then to LOW-DENSITY LIPOPROTEINS from which cholesterol is delivered to the extrahepatic tissues.
Triglycerides
Lipids
A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed)
Apolipoprotein B-100
A 513-kDa protein synthesized in the LIVER. It serves as the major structural protein of low-density lipoproteins (LIPOPROTEINS, LDL; LIPOPROTEINS, VLDL). It is the ligand for the LDL receptor (RECEPTORS, LDL) that promotes cellular binding and internalization of LDL particles.
Apolipoprotein B-48
A 241-kDa protein synthesized only in the INTESTINES. It serves as a structural protein of CHYLOMICRONS. Its exclusive association with chylomicron particles provides an indicator of intestinally derived lipoproteins in circulation. Apo B-48 is a shortened form of apo B-100 and lacks the LDL-receptor region.

Tangier Disease
An autosomal recessively inherited disorder caused by mutation of ATP-BINDING CASSETTE TRANSPORTERS involved in cellular cholesterol removal (reverse-cholesterol transport). It is characterized by near absence of ALPHA-LIPOPROTEINS (high-density lipoproteins) in blood. The massive tissue deposition of cholesterol esters results in HEPATOMEGALY; SPLENOMEGALY; RETINITIS PIGMENTOSA; large orange tonsils; and often sensory POLYNEUROPATHY. The disorder was first found among inhabitants of Tangier Island in the Chesapeake Bay, MD.
Phosphatidylcholine-Sterol O-Acyltransferase
An enzyme secreted from the liver into the plasma of many mammalian species. It catalyzes the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the C-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma. EC 2.3.1.43.
Lipoproteins, LDL
A class of lipoproteins of small size (18-25 nm) and light (1.019-1.063 g/ml) particles with a core composed mainly of CHOLESTEROL ESTERS and smaller amounts of TRIGLYCERIDES. The surface monolayer consists mostly of PHOSPHOLIPIDS, a single copy of APOLIPOPROTEIN B-100, and free cholesterol molecules. The main LDL function is to transport cholesterol and cholesterol esters to extrahepatic tissues.

Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .
Abetalipoproteinemia
An autosomal recessive disorder of lipid metabolism. It is caused by mutation of the microsomal triglyceride transfer protein that catalyzes the transport of lipids (TRIGLYCERIDES; CHOLESTEROL ESTERS; PHOSPHOLIPIDS) and is required in the secretion of BETA-LIPOPROTEINS (low density lipoproteins or LDL). Features include defective intestinal lipid absorption, very low serum cholesterol level, and near absent LDL.

A highly dense subclass of the high-density lipoproteins, with particle sizes below 7 nm. They are also known as nascent HDL, composed of a few APOLIPOPROTEIN A-I molecules which are complexed with PHOSPHOLIPIDS. The lipid-poor pre-beta-HDL particles serve as progenitors of HDL3 and then HDL2 after absorption of free cholesterol from cell membranes, cholesterol esterification, and acquisition of apolipoproteins A-II, Cs, and E. Pre-beta-HDL initiate the reverse cholesterol transport process from cells to liver.

Receptors, LDL
Receptors on the plasma membrane of nonhepatic cells that specifically bind LDL. The receptors are localized in specialized regions called coated pits. Hypercholesteremia is caused by an allelic genetic defect of three types: 1, receptors do not bind to LDL; 2, there is reduced binding of LDL; and 3, there is normal binding but no internalization of LDL. In consequence, entry of cholesterol esters into the cell is impaired and the intracellular feedback by cholesterol on 3-hydroxy-3-methylglutaryl CoA reductase is lacking.

Lecithin Acyltransferase Deficiency
An autosomal recessively inherited disorder caused by mutation of LECITHIN CHOLESTEROL ACYLTRANSFERASE that facilitates the esterification of lipoprotein cholesterol and subsequent removal from peripheral tissues to the liver. This defect results in low HDL-cholesterol level in blood and accumulation of free cholesterol in tissue leading to a triad of CORNEAL OPACITY, hemolytic anemia (ANEMIA, HEMOLYTIC), and PROTEINURIA.

Specific regional transcription of apolipoprotein E in human brain neurons. (1/5038)

In central nervous system injury and disease, apolipoprotein E (APOE, gene; apoE, protein) might be involved in neuronal injury and death indirectly through extracellular effects and/or more directly through intracellular effects on neuronal metabolism. Although intracellular effects could clearly be mediated by neuronal uptake of extracellular apoE, recent experiments in injury models in normal rodents and in mice transgenic for the human APOE gene suggest the additional possibility of intraneuronal synthesis. To examine whether APOE might be synthesized by human neurons, we performed in situ hybridization on paraffin-embedded and frozen brain sections from three nondemented controls and five Alzheimer's disease (AD) patients using digoxigenin-labeled antisense and sense cRNA probes to human APOE. Using the antisense APOE probes, we found the expected strong hybridization signal in glial cells as well as a generally fainter signal in selected neurons in cerebral cortex and hippocampus. In hippocampus, many APOE mRNA-containing neurons were observed in sectors CA1 to CA4 and the granule cell layer of the dentate gyrus. In these regions, APOE mRNA containing neurons could be observed adjacent to nonhybridizing neurons of the same cell class. APOE mRNA transcription in neurons is regionally specific. In cerebellar cortex, APOE mRNA was seen only in Bergmann glial cells and scattered astrocytes but not in Purkinje cells or granule cell neurons. ApoE immunocytochemical localization in semi-adjacent sections supported the selectivity of APOE transcription. These results demonstrate the expected result that APOE mRNA is transcribed and expressed in glial cells in human brain. The important new finding is that APOE mRNA is also transcribed and expressed in many neurons in frontal cortex and human hippocampus but not in neurons of cerebellar cortex from the same brains. This regionally specific human APOE gene expression suggests that synthesis of apoE might play a role in regional vulnerability of neurons in AD. These results also provide a direct anatomical context for hypotheses proposing a role for apoE isoforms on neuronal cytoskeletal stability and metabolism.  (+info)

Transcription factor AP-2 activity is modulated by protein kinase A-mediated phosphorylation. (2/5038)

We recently reported that APOE promoter activity is stimulated by cAMP, this effect being mediated by factor AP-2 [Garcia et al. (1996) J. Neurosci. 16, 7550-7556]. Here, we study whether cAMP-induced phosphorylation modulates the activity of AP-2. Recombinant AP-2 was phosphorylated in vitro by protein kinase A (PKA) at Ser239. Mutation of Ser239 to Ala abolished in vitro phosphorylation of AP-2 by PKA, but not the DNA binding activity of AP-2. Cotransfection studies showed that PKA stimulated the effect of AP-2 on the APOE promoter, but not that of the S239A mutant. Therefore, cAMP may modulate AP-2 activity by PKA-induced phosphorylation of this factor.  (+info)

Age of onset in Huntington disease: sex specific influence of apolipoprotein E genotype and normal CAG repeat length. (3/5038)

Age of onset (AO) of Huntington disease (HD) is known to be correlated with the length of an expanded CAG repeat in the HD gene. Apolipoprotein E (APOE) genotype, in turn, is known to influence AO in Alzheimer disease, rendering the APOE gene a likely candidate to affect AO in other neurological diseases too. We therefore determined APOE genotype and normal CAG repeat length in the HD gene for 138 HD patients who were previously analysed with respect to CAG repeat length. Genotyping for APOE was performed blind to clinical information. In addition to highlighting the effect of the normal repeat length upon AO in maternally inherited HD and in male patients, we show that the APOE epsilon2epsilon3 genotype is associated with significantly earlier AO in males than in females. Such a sex difference in AO was not apparent for any of the other APOE genotypes. Our findings suggest that subtle differences in the course of the neurodegeneration in HD may allow interacting genes to exert gender specific effects upon AO.  (+info)

Competition of Abeta amyloid peptide and apolipoprotein E for receptor-mediated endocytosis. (4/5038)

The genetic polymorphism of apolipoprotein E (apoE) is associated with the age of onset and relative risk of Alzheimer's disease (AD). In contrast to apoE3, the wild type allele, apoE4 confers an increased risk of late-onset AD. We demonstrate that the beta-amyloid peptide isoforms Abeta (1-28), Abeta (1-40), and Abeta (1-43) compete for the cellular metabolism of apoE3 and apoE4 containing beta-very low density lipoproteins. An antibody raised against Abeta (1-28) cross-reacted with recombinant apoE. Epitope mapping revealed positive amino acid clusters as common epitopes of Abeta (13 through 17; HHQKL) and apoE (residues 144 through 148; LRKRL), both regions known to be heparin binding domains. Abeta in which amino acids 13 through 17 (HHQKL) were replaced by glycine (GGQGL) failed to compete with the cellular uptake of apoE enriched betaVLDL. These observations indicate that Abeta and apoE are taken up into cells by a common pathway involving heparan sulfate proteoglycans.  (+info)

Mass spectral study of polymorphism of the apolipoproteins of very low density lipoprotein. (5/5038)

New isoforms of apolipoprotein (apo)C-I and apoC-III have been detected in delipidated fractions from very low density lipoprotein (VLDL) using matrix-assisted laser desorption (MALDI) and electrospray ionization (ESI) mass spectrometry (MS). The cleavage sites of truncated apoC-III isoforms have also been identified. The VLDL fractions were isolated by fixed-angle single-spin ultracentrifugation using a self-generating sucrose density gradient and delipidated using a newly developed C18 solid phase extraction protocol. Fifteen apoC isoforms and apoE were identified in the MALDI spectra and the existence of the more abundant species was verified by ESI-MS. The relative intensities of the apoCs are closely correlated in three normolipidemic subjects. A fourth subject with type V hyperlipidemia exhibited an elevated apoC-III level and a suppressed level of the newly discovered truncated apoC-I isoform. ApoC-II was found to be particularly sensitive to in vitro oxidation. The dynamic range and specificity of the MALDI assay shows that the complete apoC isoform profile and apoE phenotype can be obtained in a single measurement from the delipidated VLDL fraction.  (+info)

beta-amyloid load is not influenced by the severity of cardiovascular disease in aged and demented patients. (6/5038)

BACKGROUND AND PURPOSE: This study was conducted to analyze the association between reported risk factors for Alzheimer's disease, apolipoprotein E epsilon4 allele, and cardiovascular disease and neuropathological changes essential for the diagnosis of Alzheimer's disease. METHODS: Our data are based on clinical and postmortem evaluations of a cohort of nondemented (n=118) and demented (n=107) individuals. A cardiovascular index was calculated at autopsy to estimate the extent of cardiovascular disease. Neuropathological lesions such as senile/neuritic plaques, neurofibrillary tangles, beta-amyloid load, cerebral amyloid angiopathy, and the load of paired helical filaments were determined. RESULTS: The aforementioned neuropathological lesions did not show any positive significant correlation with cardiovascular index. In contrast, the extent of Alzheimer's lesions was significantly higher in those nondemented and demented patients carrying the apolipoprotein E epsilon4 allele than in those without this allele. CONCLUSIONS: Our results demonstrate that the apolipoprotein E epsilon4 allele, but not cardiovascular disease, indeed influences the extent of Alzheimer's lesions seen in the brain tissue of demented patients as well as asymptomatic controls.  (+info)

Apo E phenotype and changes in serum lipids in adult patients during growth hormone replacement. (7/5038)

OBJECTIVE: To determine whether apo E phenotype influences changes in lipid profiles induced by growth hormone replacement in growth hormone (GH)-deficient adults. DESIGNS: Patients were treated for 6 months with recombinant human GH (hGH), given in a dose of 0.125 U/kg per week for 4 weeks followed by 0.25 U/kg per week thereafter. The effects on serum lipids and the influence of apo E phenotype were examined. METHODS: Thirty patients (aged 35.1+/-11.8 years: mean +/- S.D.) with adult growth hormone deficiency with included in the study. Fasting serum samples were analysed for apo E phenotype total cholesterol, high-density lipoprotein (HDL)-cholesterol, triglycerides, lipoprotein (a) (Lp(a)) and IGF-I. Low-density lipoprotein (LDL)-cholesterol was calculated using the Friedwald formula. RESULTS: Six months of replacement treatment with hGH resulted in a reduction in HDL-cholesterol from 0.90+/-0.10 to 0.68+/-0.08 mmol/l (P<0.01), and a small, non-significant reduction in total cholesterol from 6.14+/-0.40 to 5.99+/-0.35 mmol/l (P = 0.06). There was no significant change in the other lipid parameters. The decrease in HDL-cholesterol concentration was greater in patients carrying the apo E2 allele (0.40+/-0.07 mmol/l, P<0.05) than in patients homozygous for the apo E3 allele (0.23+/-0.04 mmol/l) and patients carrying the apo E4 allele (0.15+/-0.36 mmol/l). Patients with the apo E4 allele had lower baseline cholesterol concentrations than patients lacking the apo E4 allele, and this persisted after treatment with hGH (P<0.05). CONCLUSIONS: Apo E phenotype may be a determining factor in the response of HDL-cholesterol to hGH in GH-deficient adults.  (+info)

Iron-deficient diet reduces atherosclerotic lesions in apoE-deficient mice. (8/5038)

BACKGROUND: Iron deposition is evident in human atherosclerotic lesions, suggesting that iron may play a role in the development of atherosclerosis. To test this idea, the correlation between the extent of iron deposition and the severity of atherosclerosis in apolipoprotein E (apoE)-deficient mice was investigated. Furthermore, the effect of a low-iron diet on the progression of atherosclerotic lesions in these animals was evaluated. METHODS AND RESULTS: Iron deposition in tissues of apoE-deficient mice was examined by Perls' staining method. The results clearly demonstrated that iron deposits are present in atherosclerotic lesions and tissue sections of heart and liver in an age-dependent manner. When the young mice received a low-iron diet for 3 months, the hematocrit, serum iron, hemoglobin, and cholesterol concentrations were not significantly altered compared with those of littermates placed on a chow diet. However, the serum ferritin level of animals in the iron-restricted group was 27% to 30% lower than that of the control group in either sex. Furthermore, the lipoproteins isolated from the iron-restricted group exhibited greater resistance to copper-induced oxidation. Histological examination revealed that atherosclerotic lesions developed in mice fed a low-iron diet were significantly smaller than those found in control littermates. Likewise, the iron deposition as well as tissue iron content was much less in aortic tissues of the iron-restricted animals. Circulating autoantibodies to oxidized LDL and immunostains for epitopes of malondialdehyde-modified LDL detected on lesions were also significantly lower in mice fed a low-iron diet. CONCLUSIONS: Iron deposition is closely associated with the progression of atherosclerosis in apoE-deficient mice. Restriction in dietary iron intake leads to significant inhibition of lesion formation in these animals. These results suggest that the beneficial effect of a low-iron diet may be mediated, at least in part, by the reduction of iron deposition as well as LDL oxidation in vascular lesions.  (+info)

OBJECTIVE: To test the non-lipid-lowering effects of simvastatin on the response to injury in normolipidemic and hyperlipidemic mice. METHODS AND RESULTS: Wild-type (WT) mice (n = 40) and hyperlipidemic apolipoprotein-E-deficient (apoE(-/-)) mice (n = 40) received normal chow or chow containing simvastatin 100 mg/kg/day prior to bilateral femoral artery wire injury. Intimal hyperplasia and plasma cholesterol concentration were quantified after 4 weeks. Plasma cholesterol in WT mice treated or untreated with simvastatin was similar (100.9 +/- 6.6 vs. 94.3 +/- 17.5 mg/dl). Simvastatin did not affect intimal hyperplasia. In apoE(-/-) mice, intimal hyperplasia was increased 2.3-fold relative to WT mice (17090 +/- 4998 vs. 39490 +/- 16190; p | 0.001). In apoE(-/- )mice, simvastatin caused a paradoxical increase in plasma cholesterol (1094 +/- 60.3 vs. 658 +/- 66.8 mg/dl; p | 0.001), confirmed by FPLC. This was associated with a further increase in intimal area (39490 +/- 16190 vs. 55420 +/- 22590 mm(2); p |

Overexpression of perilipin1 protects against atheroma progression in apolipoprotein E knockout mice : HUSCAPOverexpression of perilipin1 protects against atheroma progression in apolipoprotein E knockout mice : HUSCAP
Background and aims: Perilipin1 (PLIN1), a lipid droplet-associated protein, plays an important role in the regulation of lipolysis and lipid storage in adipocytes. PLIN1 has recently been reported to be expressed in macrophages within atheroma plaques, suggesting PLIN1 may play a role in the accumulation of lipids at the arterial wall and in the development of atherosclerosis. To clarify the role of PLIN1 in the pathophysiology of atherosclerosis, we assessed the progression of atherosclerosis in PLIN1 transgenic mice (Plin1Tg). Methods: Plin1Tg were crossed with apolipoprotein E knockout mice (ApoeKO). C57BL/6J mice, ApoeKO and Plin1Tg/ApoeKO received a normal chow diet for 20 weeks. Body weight, gonadal fat mass and plasma lipid concentrations were measured. Aortas were collected for quantification of atheroma lesions and histological analysis by Oil Red O staining. Results: Body weight, gonadal adipose mass and plasma triglyceride concentrations were not significantly different among the ...

Blood donors of the Madrid area show a 6% frequency of apolipoprotein E genotype carrying allele epsilon 4. This frequency is smaller than other populations of Caucasian origin. This proportion decreases to 4% in a selected sample of healthy individuals of ages | 60 years. The frequency (34%) of the allele epsilon 4 was significantly increased in patients of late onset Alzheimers disease, similarly to other populations. An earlier age of onset of the dementia is observed in the patients of late-onset Alzheimers disease carrying the allele epsilon 4. No increased frequency in allele epsilon 4 frequency was found in patients of early-onset Alzheimers disease. Patients of Parkinsons disease do not show any differences in the frequency of the alleles of apolipoprotein E when compared with healthy individuals.

Expression of the human apolipoprotein E gene suppresses steroidogenesis in mouse Y1 adrenal cells. | PNASExpression of the human apolipoprotein E gene suppresses steroidogenesis in mouse Y1 adrenal cells. | PNAS
The lipid transport protein, apolipoprotein E (apoE), is expressed in many peripheral tissues in vivo including the adrenal gland and testes. To investigate the role of apoE in adrenal cholesterol homeostasis, we have expressed a human apoE genomic clone in the Y1 mouse adrenocortical cell line. Y1 cells do not express endogenous apoE mRNA or protein. Expression of apoE in Y1 cells resulted in a dramatic decrease in basal steroidogenesis; secretion of fluorogenic steroid was reduced 7- to greater than 100-fold relative to Y1 parent cells. Addition of 5-cholesten-3 beta,25-diol failed to overcome the suppression of steroidogenesis in these cells. Cholesterol esterification under basal conditions, as measured by the production of cholesteryl [14C]oleate, was similar in the Y1 parent and the apoE-transfected cell lines. Upon incubation with adrenocorticotropin or dibutyryl cAMP, production of cholesteryl [14C]oleate decreased 5-fold in the Y1 parent cells but was unchanged in the apoE-transfected ...

Regulation of Endogenous Apolipoprotein E Secretion by Macrophages | Arteriosclerosis, Thrombosis, and Vascular BiologyRegulation of Endogenous Apolipoprotein E Secretion by Macrophages | Arteriosclerosis, Thrombosis, and Vascular Biology
Recent studies in other systems have demonstrated that constitutive protein secretion is regulated, and involves kinases, phosphatases, receptors, and typically, the microtubule network.76,83,84 In view of previous studies indicating that apoE secretion could be stimulated by apoA-I and by HDL,17,19,38,47 we hypothesized that even basal apoE secretion must be under some form of regulation. We showed that disruption of microtubules inhibited basal apoE secretion, whereas disruption of the actin skeleton had no effect. Microscopy studies supported this by showing alignment of apoE-containing vesicles along the microtubules but not the actin cytoskeleton in RAW macrophages.49. Protein kinase A (PKA) regulates traffic of several proteins at different steps in the constitutive secretory pathway,85 and a range of PKA inhibitors decreased secretion of apoE.49 Live cell imaging of apoE-GFP-transfected RAW macrophages indicated that PKA is required for the movement of apoE-containing vesicles. ...

Background: Air pollution is associated with significant adverse health effects including increased cardiovascular morbidity and mortality. However research on the cardiovascular effect of real-world exposure to ambient particulate matter (PM) in susceptible animal model is very limited. In this study, we aimed to investigate the association between Beijing ambient particle exposure and the atherosclerosis development in the apolipoprotein E knockout mice (ApoE-/-mice).. Methods: Two parallel exposure chambers were used for whole body exposure among ApoE knockout mice. One of the chambers was supplied with untreated ambient air (PM group) and the other chamber was treated with ambient air filtered by high-efficiency particulate air (HEPA) filter (FA group). Twenty mice were divided into two groups and exposed to ambient PM (n = 10 for PM group) or filtered air(n = 10 for FA group) for two months from January 18th to March 18th, 2010. During the exposure, the mass concentrations of PM2.5 and ...

Despite apolipoprotein Es important role in cholesterol transport and metabolism in the brain as well as its influence on Alzheimers disease, the impact of the human APOE genotype on cholesterol metabolism in brain has not been fully examined. This study was carried out to investigate APOE genotype effects on oxysterols measured. In this study the measurement of cholesterol and several oxysterols in the brains of human APOE ε2, ε3 and ε4 knock-in mice at 8 weeks and 1 year of age using gas chromatography mass spectrometry (GC-MS) demonstrated no APOE genotype or age effect on total brain cholesterol and the oxysterol 24-hydroxycholesterol. The level of 27-hydroxycholesterol was elevated in 1 year old animals for all APOE genotypes. Interestingly, lathosterol an indicator of cholesterol synthesis was significantly reduced in the 1 year old animals for all APOE genotypes. APOE ε4 expressing mice exhibited statistically lower levels of lathosterol compared to APOE ε2 in both the young and ...

Despite pleiotropic immunomodulatory effects of apolipoprotein E (apoE) in vitro, its effects on the clinical course of experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) are still controversial. As sex hormones modify immunomodulatory apoE functions, they may explain contentious findings. This study aimed to investigate sex-specific effects of apoE on disease course of EAE and MS. MOG35-55 induced EAE in female and male apoE-deficient mice was assessed clinically and histopathologically. apoE expression was investigated by qPCR. The association of the MS severity score (MSSS) and APOE rs429358 and rs7412 was assessed across 3237 MS patients using linear regression analyses. EAE disease course was slightly attenuated in male apoE-deficient (apoE −/− ) mice compared to wildtype mice (cumulative median score: apoE −/− = 2 [IQR 0.0-4.5];

Lipoprotein glomerulopathy (LPG) is a rare autosomal dominant kidney disease that is most commonly caused by mutations in ApoE Kyoto (p.R43C) and ApoE Sendai (p.R163P). Differences in phenotype among the various ApoE mutations have been suggested, but the pathogenic role of ApoE Kyoto has not been validated in an animal model. This study intended to establish an ApoE Kyoto murine model and to further compare the pathologic differences between ApoE Kyoto and ApoE Sendai. Male ApoE-deficient mice, 3 months of age, were divided into five groups, including the AD-ApoE Sendai, AD-ApoE Kyoto, AD-ApoE3, AD-eGFP, and ApoE (−/−) groups. The first four groups received recombinant adenovirus that contained the entire coding regions of the human ApoE Sendai and ApoE Kyoto, apoE3, and eGFP genes, respectively. Fasting blood and urine samples were collected at multiple time points. Lipid profiles and urine albumin-creatinine ratio were measured. Renal and aortic histopathologic alterations were analyzed.

Given its ability to detect apoE in amyloid plaques (Fig. 1 F), we selected HJ6.3 antibody for anti-apoE immunization experiments. To determine whether anti-apoE antibody would have an antiamyloidogenic effect, we injected PBS or anti-apoE antibody (HJ6.3) weekly at 10 mg of antibody/kg of body weight per dose. 4-mo-old male APPswe/PS1ΔE9 mice were intraperitoneally injected for 14 wk. Brain tissues were processed for histochemical and biochemical analyses. Quantitative analyses of anti-Aβ immunostaining (Fig. 2, A and B) demonstrated that Aβ plaque load in the cortex (Fig. 2 C) and hippocampus (Fig. 2 D) was markedly decreased by HJ6.3 antibody treatment, compared with the PBS-treated control group. There was a strong 70-80% reduction in Aβ plaque load in the cortex (Fig. 2 C) and hippocampus (Fig. 2 D). HJ6.3 treatment also significantly decreased the number of plaques per area in the cortex (Fig. 2 E) and hippocampus (Fig. 2 F). To further characterize the structural nature of the ...

article{a4a89a77-6245-40ad-adfc-12ba8e92c5b8, abstract = {OBJECTIVE: Atherosclerosis is an inflammatory disease. Several chemokines are important for monocyte/macrophage and T-cell recruitment to the lesion. CXCL16 is a recently discovered chemokine that is expressed in soluble and transmembrane forms, ligates CXCR6 chemokine receptor, and guides migration of activated Th1 and Tc1 cells. It is identical to scavenger receptor SR-PSOX, which mediates uptake of oxidized low-density lipoprotein. We investigated whether CXCL16 expression is controlled by interferon-gamma (IFN-gamma)-cytokine abundant in atherosclerotic lesions. METHODS AND RESULTS: CXCL16 and CXCR6 expression was identified by polymerase chain reaction and histochemistry in atherosclerotic lesions from humans and apolipoprotein-E-deficient mice.

Background: A fundamental question in Alzheimers disease (AD) is whether amyloid-β (Aβ) peptides and their deposition in the brain signify a direct pathological role or they are mere outcome of the disease pathophysiological events affecting neuronal function. It is therefore important to decipher their physiological role in the brain. So far, the overwhelming focus has been on the potential toxicity of Aβ, often studied outside the crucial AD characteristics, i.e.: (i) the slow, decades-long disease progression that precedes clinical symptoms; (ii) the link to apolipoprotein-E ε4 allele as major risk factor; (iii) the selective early degeneration of cholinergic neurons. Previous studies, in vitro and cerebrospinal fluid (CSF) only, indicated one possible native function of Aβ peptides is the allosteric modulation of acetylcholine homeostasis, via molecular interactions between Aβ, apolipoprotein-E, and the acetylcholine-degrading enzymes, cholinesterases, resulting in the formation of

Background-CD4+CD25+Foxp3+ regulatory T cells (Tregs) attenuate atherosclerosis but their therapeutic application by adoptive transfer is limited by the need for their expansion in vitro and limited purity. Recently, an IL-2/anti-IL-2 neutralizing mAb (IL-2/anti-IL-2 mAb) complex has been shown to expand these Tregs. We examined the capacity of a modified IL-2/anti-IL-2 mAb treatment to expand Tregs and inhibit both the progression and development of developed atherosclerosis. Methods and Results-Six-week old apolipoprotein-E-deficient mice fed a high fat diet for 8 weeks were administered IL-2/anti-IL-2 mAb commencing 2 weeks after starting the diet. Tregs in the spleen, lymph node and liver were selectively expanded without affecting CD4+, CD8+ or NK cells. Tregs were increased in lesions and lesion size reduced. CD4+ T-cells, macrophages, mature dendritic cells, PCNA+ cells and MCP-1 and VCAM-1 were reduced. In anti-CD3 stimulated splenocytes, proliferation and secretion of Th1, Th2, Th17 ...

Although dietary fat is considered to be one of the risk factors for cardiovascular diseases, it is not well understood whether a high fat content in diet has an effect on lipid metabolism and on atherosclerotic lesion development when the amount of cholesterol in the diet is low. To address this issue and to study possible mechanisms by which dietary fat regulates such parameters, we have conducted a dietary trial in which apoE-knockout mice were given 7 different diets for 10 weeks. We found that dietary fat supplement without addition of cholesterol does not increase lesion sizes either in males or females. On the contrary, palm and olive II oils significantly reduced lesion size but only in female mice. Furthermore, different types of fat have different effects, and even a particular oil from different cultivars has different effects, as in the case of olive oil I and II. Reduction in lesion size was independent of plasma cholesterol levels because no change in the latter was observed in any ...

The apelin pathway has emerged as a critical regulator of cardiovascular homeostasis and disease. However, the exact role of pyr1-apelin-13 in angiotensin (Ang) II-mediated heart disease remains unclear. We used apelin-deficient (APLN−/y) and apolipoprotein E knockout mice to evaluate the regulatory roles of pyr1-apelin-13. The 1-year aged APLN−/y mice developed myocardial hypertrophy and dysfunction with reduced angiotensin-converting enzyme 2 levels. Ang II infusion (1.5 mg kg−1 d−1) for 4 weeks potentiated oxidative stress, pathological hypertrophy, and myocardial fibrosis in young APLN−/y hearts resulting in exacerbation of cardiac dysfunction. Importantly, daily administration of 100 μg/kg pyr1-apelin-13 resulted in upregulated angiotensin-converting enzyme 2 levels, decreased superoxide production and expression of hypertrophy- and fibrosis-related genes leading to attenuated myocardial hypertrophy, fibrosis, and dysfunction in the Ang II-infused apolipoprotein E knockout mice. ...

Therapeutic enhancement of neovascularization is one of the most important strategies needed to limit the complications of postischemic injury.2-4 However, many factors shown to play an important role in neovascularization, such as MCP-1 and VEGF, are potent proinflammatory mediators and promote the development and progression of atherosclerosis with an unstable potential in various experimental models,12,13 making their potential use in patients with advanced atherosclerosis unsuitable and even hazardous in acutely ill patients. The recent identification of a central role for BM-MNCs in tissue revascularization and preservation of function after ischemic injury has renewed the great hope for an efficient proangiogenic therapy with reduced side effects. As atherosclerotic plaque instability is the most important trigger of ischemic injury in patients who would benefit from proangiogenic therapies, these strategies should be evaluated for their potential to modulate atherosclerosis progression ...

We report several new findings that are essential for understanding how apoE is regulated in the brain. The highest levels of apoE mRNA in both control and transgenic mice were found in astrocytes of the olfactory bulb and in Bergmann glia of the cerebellum. Analysis of multiple independent lines for each construct minimizes the possibility that differences in apoE mRNA transgene expression between constructs are because of integration artifacts or position effects. In the brain, apoE gene expression under the control of the ME.1 and ME.2 domains was detected only in astrocytes. Our data further suggest that astrocytes are responsible for a majority of apoE expression in the absence of inflammatory signals.. Astrocyte apoE expression was specified by distal regions located 3.3 kb and 15 kb downstream of the apoE gene. These distal sequences are 95% identical in nucleotide sequence, and they probably arose from the duplication event that yielded the two apoC-I genes (Fig. 1). In the absence of ...

Expression of Human Apolipoprotein E Downregulates Amyloid Precursor Protein-Induced Ischemic Susceptibility | StrokeExpression of Human Apolipoprotein E Downregulates Amyloid Precursor Protein-Induced Ischemic Susceptibility | Stroke
Previous studies have demonstrated that endogenous mouse apoE is protective against transient focal and global brain ischemia and traumatic brain injury.34-36⇓⇓ Although human apoE isoforms markedly delay the appearance of Aβ deposition in APPV717F transgenic mice,14 apoE ultimately facilitates the neuritic degeneration associated with amyloid deposits and with conversion of Aβ into mature fibrillar amyloid,15 which is thought to be neurotoxic.37 In the present study, we show that neuronal overexpression of human APP751 at the level detected in early AD and Downs syndrome28 dramatically increases the susceptibility to ischemic brain damage in the absence of apoE. Moreover, expression of human apoE3 or apoE4 in astrocytes significantly reduces the neuronal vulnerability to ischemia in APP751 transgenic mice. These results indicate that even though apoE may be a contributory factor in Aβ-induced toxicity in AD, it has a beneficial role against APP751-induced ischemic vulnerability. ...

The effects of APOE on the functional architecture of the resting brain. - Department of PsychiatryThe effects of APOE on the functional architecture of the resting brain. - Department of Psychiatry
There is a well-established association between APOE genotype and the risk of developing Alzheimers disease (AD). Relative to individuals with the common ε3/ε3 genotype, carriers of the ε4 allele are at increased risk of developing AD, while carriers of the ε2 allele appear to be protected against the disease. However, we recently reported that in a sample of cognitively healthy adults, both ε4 and ε2 carriers showed nearly identical changes in the pattern of fMRI activity during memory and non-memory tasks, relative to ε3 homozygotes. These findings suggest that the effects of APOE on brain function are not tightly linked to the effects of this gene on AD risk. Here we test the hypothesis that APOE has an intrinsic effect on the brains functional networks. Resting-state fMRI was used to compare the pattern of functional connectivity of a variety of resting-state networks between 77 cognitively healthy participants aged 32 to 55 with different APOE genotypes (23 ε2/ε3, 20 ε3/ε3, 26 ε3/ε4,

The ability to selectively deliver compounds into atherosclerotic plaques would greatly benefit the detection and treatment of atherosclerotic disease. We describe such a delivery system based on a 9-amino acid cyclic peptide, LyP-1. LyP-1 was originally identified as a tumor-homing peptide that specifically recognizes tumor cells, tumor lymphatics, and tumor-associated macrophages. As the receptor for LyP-1, p32, is expressed in atherosclerotic plaques, we tested the ability of LyP-1 to home to plaques. Fluorescein-labeled LyP-1 was intravenously injected into apolipoprotein E (ApoE)-null mice that had been maintained on a high-fat diet to induce atherosclerosis. LyP-1 accumulated in the plaque interior, predominantly in macrophages. More than 60% of cells released from plaques were positive for LyP-1 fluorescence. Another plaque-homing peptide, CREKA, which binds to fibrin-fibronectin clots and accumulates at the surface of plaques, yielded fewer positive cells. Tissues that did not contain plaque

The Apo E genotype of 86 patients with Alzheimers disease (AD) and 77 age matched controls was determined by digestion of Apo E PCR products with the restriction enzyme CfoI. The frequency of the e4 allele was significantly increased in the patient group (0.33) as compared with controls (0.12). This effect was seen in patients with a family history and in sporadic cases. The odds ratio in homozygotes for the e4 allele was 11.24 (95% confidence interval 2.45-51.50). There was no relationship between age of onset and Apo E genotype. There was no linkage disequilibrium between the apolipoprotein E locus and a TaqI polymorphism at the Apo CII locus, and no allelic association between Apo CII and AD.. ...

INTRODUCTION The development of atherosclerotic lesion is initiated with the accumulation of cholesterol in monocyte-derived macrophages (2,3) as well as with the retention of lipoproteins in the extracellular matrix of the subendothelial wall (22,30). Extracellular matrix (ECM) contains collagen and elastic fibers embedded in a viscoelastic gel consisting of proteoglycans (PGs), hyaluronan and glycoproteins (29). Arterial ECM contributes to the trapping of LDL and oxidized LDL (Ox-LDL) in the arterial wall, a phenomenon called lipoprotein retention (7, 18, 31). Specifically, the PGs from the ECM were shown to be responsible for the entrapment of LDL and Ox-LDL in the arterial wall (19, 27). Moreover, we have shown that subsequent to their binding to the matrix, LDL and Ox-LDL are taken up by macrophages (20). ECM can be produced in vitro by arterial cells, including endothelial cells, smooth muscle cells and also by macrophages (19). The amount and composition of ECM produced by all major ...

Apolipoprotein E ( ApoE ) gene polymorphism is a major factor in lipid metabolism. It has been suggested that this polymorphism can modulate colorectal tumour risk. We tested this hypothesis for colorectal cancer (CRC). ApoE genotype was determined in 206 patients with CRC and 353 healthy controls from the East Anglia region of the U.K. Compared with individuals possessing the most common ɛ3/ɛ3 genotype, those with the ɛ2/ɛ3 genotype had an increased risk of colon cancer [odds ratio (OR) = 1.91; 95% confidence interval 1.05-3.45]. However, this association was strongly affected by gender. Separate analysis of male and female subjects revealed a highly significant association in men (OR = 2.71; 95% confidence interval 1.30-5.65), but no association in women (OR = 1.01; 95% confidence interval 0.37-2.77). Likewise, the proportion of male patients with more advanced tumours (Dukes C&D) was significantly increased among those with the ApoE ε2/ε3 genotype (OR = 4.16; 95% confidence interval ...

This study demonstrated that CYP1B1 is critical for the development of AAL, associated inflammation, vascular damage, and hypertension in ApoE−/− mice fed AD, most likely by promoting increased oxidative stress and hyperlipidemia, which seems to be independent of lipid absorption. Eight-week-old ApoE−/−/Cyp1b1+/+ mice fed AD but not ND for 12 weeks developed AAL in the descending thoracic and abdominal aorta and in sections of proximal aorta. Our finding, that treatment with TMS, an inhibitor of CYP1B1 activity,19 for 12 weeks in ApoE−/−/Cyp1b1+/+ mice fed AD minimized AAL, suggests that CYP1B1 activity is required for the development of lesions. Although CYP1B1 is constitutively active, AD increased CYP1B1 activity without altering its expression as measured in the heart, whereas TMS inhibited its activity but not its expression. Because CYP1B1 is constitutively active, the increase in its activity by AD that could be because of biochemical modification of this enzyme remains to be ...

OBJECTIVE--To elucidate the relationship, if any, between lipid abnormalities and apolipoprotein E (apo E) polymorphism, by investigating apo E phenotype and allele frequency. METHODS--Fasting blood samples were taken for determination of apo E phenotype and serum lipids in 221 male patients with gout and 141 control male subjects. Apo E phenotype was determined by one dimensional flat gel isoelectric focusing. RESULTS--Frequencies of apo E phenotypes in gout were apo E3/3 67.9%, E4/3 18.1%, E4/4 2.3%, E4/2 1.8%, E3/2 9.5%, and E2/2 0.5%; those in control male subjects were 74.5%, 15.6%, 0%, 1.4%, 7.1%, and 1.4%, respectively. Frequencies of the e2, e3, and e4 alleles in gout were 0.061, 0.817 and 0.122, compared with the corresponding control frequencies of 0.057, 0.858 and 0.085. These differences in apo E phenotype and allele frequencies between gout and control subjects were not significant.

Inflammation plays a key role in the atherosclerotic process. As part of a study on the influence of cigarette mainstream smoke (ms) in combination with high-fat diet on the development of atherosclerosis, we investigated the inflammatory response and histopathological alterations in lungs from Apolipoprotein E-deficient (ApoE -/-) mice, a classic model for atherosclerosis. Male ApoE -/- mice were whole-body exposed for 12 months (6 h/d, 5 d/wk) to diluted MS at total particulate matter (TPM) concentrations of 100 and 200 μg/l or to filtered fresh air. Each exposure group was fed either a chow diet or a milk-fat-enriched diet. Bronchoalveolar lavage (BAL) was performed and inflammatory cells were quantified in BAL fluid (BALF); lungs were evaluated histopathologically. Mice exposed to 100 μg TPM/l MS showed no statistically significant inflammatory and epithelial changes in the lung. Mice exposed to 200 μg TPM/l MS showed statistically significant inflammatory changes, i.e., a constant ...

Oxidative stress and inflammation are central mediators of atherosclerosis particularly in the context of diabetes. The potential interactions between the major producers of vascular reactive oxygen species (ROS), NADPH oxidase (NOX) enzymes and immune-inflammatory processes remain to be fully elucidated. In the present study we investigated the roles of the NADPH oxidase subunit isoforms, NOX4 and NOX1, in immune cell activation and recruitment to the aortic sinus atherosclerotic plaque in diabetic ApoE−/− mice. Plaque area analysis showed that NOX4- and NOX1-derived ROS contribute to atherosclerosis in the aortic sinus following 10 weeks of diabetes. Immunohistochemical staining of the plaques revealed that NOX4-derived ROS regulate T-cell recruitment. In addition, NOX4-deficient mice showed a reduction in activated CD4+ T-cells in the draining lymph nodes of the aortic sinus coupled with reduced pro-inflammatory gene expression in the aortic sinus. Conversely, NOX1-derived ROS appeared to ...

Apolipoprotein E (ApoE) is a multifunctional protein, and its deficiency leads to the development of atherosclerosis in mice. Patients with pulmonary hypertension (PH) have reduced expression of ApoE in lung tissue. ApoE is known to inhibit endothelial and smooth muscle cell proliferation and has anti-inflammatory and anti-platelet aggregation properties. Young ApoE-deficient mice have been shown to develop PH on high fat diet. The combined role of female sex and aging in the development of PH has not been investigated before. Here, we investigated the development of PH in young and middle-aged (MA) female ApoE-deficient mice and explored the role of exogenous estrogen (E2) replacement therapy for the aging females. Wild type (WT) and ApoE-deficient female mice (Young and MA) were injected with a single intraperitoneal dose of monocrotaline (MCT, 60 mg/kg). Some ApoE-deficient MA female mice that received MCT were also treated with subcutaneous E2 pellets (0.03 mg/kg/day) from day 21 to 30 after MCT

Apolipoprotein E4 allele as a predictor of cholinergic deficits and treatment outcome in Alzheimer disease | PNASApolipoprotein E4 allele as a predictor of cholinergic deficits and treatment outcome in Alzheimer disease | PNAS
Apolipoprotein E (apoE) is critical in the modulation of cholesterol and phospholipid transport between cells of different types. Human apoE is a polymorphic protein with three common alleles, APO epsilon 2, APO epsilon 3, and APO epsilon 4. ApoE4 is associated with sporadic and late-onset familial Alzheimer disease (AD). Gene dose was shown to have an effect on risk of developing AD, age of onset, accumulation of senile plaques in the brain, and reduction of choline acetyltransferase (ChAT) activity in the hippocampus of AD subjects. To characterize the possible impact of the apoE4 allele on cholinergic markers in AD, we examined the effect of apoE4 allele copy number on pre- and postsynaptic markers of cholinergic activity. ApoE4 allele copy number showed an inverse relationship with residual brain ChAT activity and nicotinic receptor binding sites in both the hippocampal formation and the temporal cortex of AD subjects. AD cases lacking the apoE4 allele showed ChAT activities close or within ...

Rationale: A number of epidemiological studies have suggested an association of hyperhomocysteinemia (HHcy) and abdominal aortic aneurysm (AAA), but discrepancies exist. In addition, we lack direct evidence supporting a causal role.. Objective: We determined the association and contribution of HHcy to AAA formation.. Methods and Results: We first performed a meta-analysis of studies involving 1489 subjects and found a strong association of HHcy and AAA (odds ratio, 7.39). Next, we used angiotensin II-infused male apolipoprotein E-deficient mice and tested whether HHcy contributes to AAA pathogenesis. Homocysteine (Hcy) supplement (1.8 g/L) in drinking water resulted in mild HHcy. Intriguingly, HHcy greatly increased the incidence of angiotensin II-induced AAA and aortic dissection in apolipoprotein E-deficient mice (vehicle versus Hcy: 50% versus 100%; ...

Exposure to diesel exhaust up-regulates iNOS expression in ApoE knockout mice (Journal Article) | SciTech ConnectExposure to diesel exhaust up-regulates iNOS expression in ApoE knockout mice (Journal Article) | SciTech Connect
Traffic related particulate matter air pollution is a risk factor for cardiovascular events; however, the biological mechanisms are unclear. We hypothesize that diesel exhaust (DE) inhalation induces up-regulation of inducible nitric oxide synthase (iNOS), which is known to contribute to vascular dysfunction, progression of atherosclerosis and ultimately cardiovascular morbidity and mortality. Methods: ApoE knockout mice (30-week) were exposed to DE (at 200 {mu}g/m{sup 3} of particulate matter) or filtered-air (control) for 7 weeks (6 h/day, 5 days/week). iNOS expression in the blood vessels and heart was evaluated by immunohistochemistry and western blotting analysis. To examine iNOS activity, thoracic aortae were mounted in a wire myograph, and vasoconstriction stimulated by phenylephrine (PE) was measured with and without the presence of the specific inhibitor for iNOS (1400 W). NF-{kappa}B (p65) activity was examined by ELISA. The mRNA expression of iNOS and NF-{kappa}B (p65) was determined ...

New aspects in the pathogenesis of diabetic atherothrombosis | JACC: Journal of the American College of CardiologyNew aspects in the pathogenesis of diabetic atherothrombosis | JACC: Journal of the American College of Cardiology
The HDLs are responsible for the removal of free cholesterol from the blood. Low plasma levels of HDL are associated with increased cardiovascular risk. Low levels of HDL are frequently seen in patients with insulin resistance, from the metabolic syndrome to overt diabetes mellitus. Badimon et al. (59,60) elegantly demonstrated the antiatherogenic properties of HDL, reducing the number of fatty streaks and inducing disease regression in the rabbit experimental model. More recently, Rong et al. (61) evaluated the effects of HDL in advanced experimental atherosclerosis. Diseased thoracic aortic segments from hypercholesterolemic apolipoprotein E-deficient mice were transplanted in the abdominal aorta of apolipoprotein E-deficient mice not expressing (plasma HDL cholesterol approximately 26 mg/dl) or expressing (HDL approximately 64 mg/dl) a human apolipoprotein AI transgene. Mice with high plasma HDL showed significant changes in plaque composition, with macrophage area reductions ,80% and ...

In this study, the effect of the myxoma virus-derived serine protease inhibitor Serp-1 was investigated on de novo atherosclerosis and on advanced atherosclerotic lesions in apoE−/− mice equipped with a perivascular collar to induce carotid artery lesions.28 Serp-1 treatment led to a striking reduction in de novo lesion formation, whereas Serp-1 did not affect plasma total cholesterol and triglyceride levels as well as the total body weight of the animals or promote outward remodeling of the carotid artery. Plasma levels of Serp-1 after subcutaneous infusion remained constant during treatment at approximately 13.5 pmol/L. These low picomolar Serp-1 levels have been reported to suffice for effective serine protease inhibition and for blocking the hosts immune response to myxoma infection.20,21 Further gel filtration analysis revealed that Serp-1 was not degraded during the timeframe of the experiment. Blood cell levels did not differ between control and Serp-1 treatment groups, suggesting ...

Role of apolipoprotein E in neurodegenerative diseases Vo Van Giau,1 Eva Bagyinszky,1 Seong Soo A An,1 SangYun Kim2 1Department of Bionano Technology, Gachon Medical Research Institute, Gachon University, Seongnam, South Korea; 2Department of Neurology, Seoul National University College of Medicine in Seoul National Bundang Hospital, Seoul, South Korea Abstract: Apolipoprotein E (APOE) is a lipid-transport protein abundantly expressed in most neurons in the central nervous system. APOE-dependent alterations of the endocytic pathway can affect different functions. APOE binds to cell-surface receptors to deliver lipids and to the hydrophobic amyloid-β peptide, regulating amyloid-β aggregations and clearances in the brain. Several APOE isoforms with major structural differences were discovered and shown to influence the brain lipid transport, glucose metabolism, neuronal signaling, neuroinflammation, and mitochondrial function. This review will summarize the updated research progress on APOE functions

The human APOE gene, which codes for apolipoprotein E (apoE), has three major polymorphic alleles: ε2, ε3, and ε4 that give rise to amino acid substitutions. APOE-ε4 is a strong risk factor of sporadic Alzheimers disease (AD) but the reason why is still unknown despite intense research for more than 20 years. The aim of the study was to investigate if the concentrations of total apoE and the specific apoE isoforms in cerebrospinal fluid (CSF) differ between various neurodegenerative diseases and control individuals, as well as among the APOE genotypes. Quantification of total apoE and specific apoE isoforms (E2, E3, and E4) in CSF was performed using high-resolution parallel reaction monitoring mass spectrometry. In total, 1820 individuals were involved in the study including clinically diagnosed AD patients (n = 228), cognitively unimpaired (CU) patients (n = 896), and patients with other neurodegenerative disorders (n = 696). Follow-up data was available for 100 individuals, assessed at two time

BACKGROUND: Compared to the epsilon 2 or epsilon 3 alleles, the epsilon 4 allele of apolipoprotein E (ApoE4) is associated with twice the prevalence of late-onset Alzheimers disease (AD). Epidemiological studies show that risk of AD varies inversely with consumption of omega-3 fatty acids from fish and seafood. Despite apparently lower fish intake in AD, pooled analysis of the literature shows that plasma and brain docosahexaenoic acid (DHA) is actually the same in AD as in healthy age-matched controls. Fish oil trials in AD are also not convincing. We recently shown that ApoE4 carriers have 41% higher fasting plasma EPA and DHA compared to non-carriers, but the plasma EPA and DHA response to fish oil in ApoE4 carriers was half that seen in non-carriers.. HYPOTHESES: (i) Carriers of ApoE4 have altered metabolism of carbon-13 (13C)-DHA as well as EPA and DHA provided in a dietary supplement. (ii) A dietary supplement of EPA+DHA will improve cognitive performance but only in non-carriers of ...

Results from two small studies, involving a total of only 174 cases, have suggested that the increased risk of coronary heart disease conferred by cigarette smoking is substantially affected by genotype at the apolipoprotein E (APOE) epsilon2/epsilon3/epsilon4 polymorphism. We have established APOE genotypes in 4484 patients with acute myocardial infarction diagnosed before the age of 55 years for male and 65 years for female patients, and in 5757 controls with no history of cardiovascular disease. On average, the hazard ratio for myocardial infarction was 1.17 (95% CI 1.09-1.25; p|0.00001) per stepwise change from epsilon3/2 to epsilon3/3 to epsilon3/4 genotype. Among individuals in this study with known cigarette smoking status, the hazard ratio for myocardial infarction in smokers versus non-smokers was 4.6 (4.2-5.1). There was, however, no significant difference between the smoker/non-smoker hazard ratios for those with different APOE genotypes (chi2(2)=0.69; p=0.7). When differences in risk between

AIMS: Vascular disease states are associated with endothelial dysfunction and increased production of reactive oxygen species derived from NADPH oxidases. However, it remains unclear whether a primary increase in superoxide production specifically in the endothelium alters the initiation or progression of atherosclerosis. METHODS AND RESULTS: Mice overexpressing Nox2 specifically in the endothelium (Nox2-Tg) were crossed with ApoE(-/-) mice to produce Nox2-Tg ApoE(-/-) mice and ApoE(-/-) littermates. Endothelial overexpression of Nox2 in ApoE(-/-) mice did not alter blood pressure, but significantly increased vascular superoxide production compared with ApoE(-/-) littermates, measured using both lucigenin chemiluminescence and 2-hydroxyethidium production (ApoE(-/-), 19.9 ± 6.3 vs. Nox2-Tg ApoE(-/-), 47.0 ± 7.0 nmol 2-hydroxyethidium/aorta, P| 0.05).

Today more than 95 percent of experimental pathology research in atherosclerosis is carried out using the apo E knockout mouse. Not only has it provided a system for studying how lesions form in arteries, it also has given scientists a way to test the effects of other genes on how atherosclerosis develops, by breeding so-called candidate genes onto the apo E knockout mouse background. In addition, when Breslow crossed the apo E knockout trait onto different inbred mouse strains, he found a wide range in the size of the lesions that formed. This indicated modifier genes, and through genetic crosses he has found additional genes involved in atherosclerosis susceptibility. The apo E knockout mouse is also widely used in the pharmaceutical industry to test compounds for treating atherosclerosis. Jan L. Breslow received the AB from Columbia College (1963), the MA from Columbia University (1964), and the MD from Harvard Medical School (1968).

Melanoma is the most aggressive skin cancer due to a propensity to metastasize and resistance to standard therapies. Nuclear hormone receptors are therapeutic targets in reproductive tissues, but their clinical utility in other solid tumors such as melanoma remains undefined. Pencheva and colleagues observed that liver-X nuclear hormone receptor β (LXRβ) was ubiquitously expressed across patient-derived melanoma cell lines and that LXR agonists inhibited invasion and endothelial cell recruitment of multiple melanoma cell lines in vitro in an LXRβ-dependent manner. Furthermore, oral administration of LXR agonists suppressed melanoma xenograft tumor growth, accompanied by a reduction in the number and size of tumoral endothelial vessels as well as lung and brain metastases. LXRβ is a known transcriptional activator of the metastasis suppressor apolipoprotein-E (ApoE), and extracellular ApoE was shown to be the primary mediator of tumor suppression by activated LXR, as antibody-mediated ...

Accumulation of β-amyloid (Aβ) in the brain is essential to Alzheimers disease (AD) pathogenesis. Carriers of the apolipoprotein E (APOE) ε4 allele demonstrate greatly increased AD risk and enhanced brain Aβ deposition. In contrast, APOE ε2 allele carries show reduced AD risk, later age of disease onset, and lesser Aβ accumulation. However, it remains elusive whether the apoE2 isoform exerts truly protective effect against Aβ pathology or apoE2 plays deleterious role albeit less pronounced than the apoE4 isoform. Here, we characterized APPSW/PS1dE9/APOE ε2-TR (APP/E2) and APPSW/PS1dE9/APOE ε4-TR (APP/E4) mice, with targeted replacement (TR) of the murine Apoe for human ε2 or ε4 alleles, and used these models to investigate effects of pharmacological inhibition of the apoE/Aβ interaction on Aβ deposition and neuritic degeneration. APP/E2 and APP/E4 mice replicate differential effect of human apoE isoforms on Aβ pathology with APP/E4 mice showing a several-fold greater load of Aβ plaques,

The apolipoprotein E (APOE) gene exists in three isoforms in humans: APOE2, APOE3 and APOE4. APOE4 causes structural and functional alterations in normal brains, and is the strongest genetic risk factor of the sporadic form of Alzheimers disease (LOAD). Research on APOE4 has mainly focused on the neuronal damage caused by defective cholesterol transport and exacerbated amyloid-β and Tau pathology. The impact of APOE4 on non-neuronal cell functions has been overlooked. Astrocytes, the main producers of ApoE in the healthy brain, are building blocks of neural circuits, and Ca2+ signaling is the basis of their excitability. Because APOE4 modifies membrane-lipid composition, and lipids regulate Ca2+ channels, we determined whether APOE4 dysregulates Ca2+signaling in astrocytes. Ca2+ signals were recorded in astrocytes in hippocampal slices from APOE3 and APOE4 gene targeted replacement male and female mice using Ca2+ imaging. Mechanistic analyses were performed in immortalized astrocytes. Ca2+ fluxes were

BLMH and APOE genes in Alzheimer Disease: A possible relationBLMH and APOE genes in Alzheimer Disease: A possible relation
ABSTRACT. Alzheimer disease (AD) is a progressive and irreversible neurodegenerative disorder that is characterized by cognitive decline, memory loss and confusion. The E4 allele of the apolipoprotein E gene (APOE) is associated with AD and it is the main genetic risk factor for disease. Although the exact physiological function is unknown, bleomycin hydrolase (BLMH) may also be associated with AD development, although previous immunohistochemical findings have been inconsistent. Therefore, the purpose of this study was to evaluate the genotypic and allele frequencies of the APOE gene and BLMH 1450 G > A polymorphism and assess BLMH expression using PCR-RFLP and RT-qPCR analyses of blood samples from patients with Alzheimer disease (AD), healthy elderly adults (EC) and healthy young subjects (YC). BLMH expression was significantly different among groups (p = 0.015) and there was substantial reduction with age and with AD. The APOE and BLMH genotype frequency did not diverge from the ...

Mice in the ApoE−/−+Sm group received Sm (0.026 g/kg) per gavage for 10 weeks. Mice in C57 group and ApoE−/− group received PBS. Pathomorphological changes of aorta were observed by Masson staining evaluating plaques collagen content, immunohistochemical staining α-actin and CD68 evaluating contents of plaques vascular smooth muscle cells and macrophages, and oil red O staining evaluating plaques adipose tissue contents. FcγRIIIA expression changes in mice with atherosclerotic plaque were determined by assaying the protein level of membrane CD16 on monocytes using immunofluorescent staining and FACS ...

LipidLipid
In animals, when there is an oversupply of dietary carbohydrate, the excess carbohydrate is converted to triglycerides. This involves the synthesis of fatty acids from acetyl-CoA and the esterification of fatty acids in the production of triglycerides, a process called lipogenesis.[87] Fatty acids are made by fatty acid synthases that polymerize and then reduce acetyl-CoA units. The acyl chains in the fatty acids are extended by a cycle of reactions that add the acetyl group, reduce it to an alcohol, dehydrate it to an alkene group and then reduce it again to an alkane group. The enzymes of fatty acid biosynthesis are divided into two groups, in animals and fungi all these fatty acid synthase reactions are carried out by a single multifunctional protein,[88] while in plant plastids and bacteria separate enzymes perform each step in the pathway.[89][90] The fatty acids may be subsequently converted to triglycerides that are packaged in lipoproteins and secreted from the liver. The synthesis of ...
