Abstract
Apolipoprotein E (apoE) is the key regulator of plasma lipids, mediating altered functionalities in lipoprotein metabolism - affecting the risk of coronary artery (CAD) and Alzheimer's diseases, as well as longevity. Searching pathways influenced by apoE prior to adverse manifestations, we utilized a metabolome dataset of 228 nuclear-magnetic-resonance-measured serum parameters with a 10-year follow-up from the population-based Young Finns Study cohort of 2,234 apoE-genotyped (rs7412, rs429358) adults, aged 24-39 at baseline. At the end of our follow-up, by limiting FDR-corrected p < 0.05, regression analyses revealed 180/228 apoE-polymorphism-related associations with the studied metabolites, in all subjects - without indications of apoE x sex interactions. Across all measured apoE- and apoB-containing lipoproteins, ε4 allele had consistently atherogenic and ε2 protective effect on particle concentrations of free/esterified cholesterol, triglycerides, phospholipids and total lipids. As novel findings, ε4 associated with glycoprotein acetyls, LDL-diameter and isoleucine - all reported biomarkers of CAD-risk, inflammation, diabetes and total mortality. ApoE-subgroup differences persisted through our 10-year follow-up, although some variation of individual metabolite levels was noticed. In conclusion, apoE polymorphism associate with a complex metabolic change, including aberrations in multiple novel biomarkers related to elevated cardiometabolic and all-cause mortality risk, extending our understanding about the role of apoE in health and disease.

Abstract
Background The dyslipidemia associated with obesity plays a major role in the development of atherosclerosis and cardiovascular disease. Dyslipidemia in childhood can progress in adult stage. APOE is one of the most important genes that regulate plasma lipid transport and clearance. The study aimed to assess whether the common APOE polymorphism is associated with lipid profiles and dyslipidemia, and it could be modulated by obesity-related traits (body mass index, waist circumference, hip circumference, and waist-to-hip ratio) in Vietnamese children. Methods A case-control study was designed including 249 cases with dyslipidemia and 600 controls without dyslipidemia. Dyslipidemia is defined as elevated total or low-density lipoprotein (LDL) cholesterol levels, or low levels of high-density lipoprotein (HDL) cholesterol. Genotype for APOE polymorphism (rs7412 and rs429358) was determined by the polymerase chain reaction and restriction fragment length polymorphism method. The association of APOE genotypes with plasma lipid disorders was tested by binary logistic regression analysis, taking into account the confounding factors of age, sex, residence, province and obesity-related traits. Results In comparison with ε3/ε3 carriers, the ε4 carriers had the highest concentration of serum TC and LDL-C in cases and controls (P ≤ 0.001), while ε2 carriers had the lowest. Carriers without TT haplotype had higher serum TC than those with TT haplotype. The ε4 carriers had higher hypoalphalipoproteinemia risk than ε3/ε3 carriers (OR = 2.78, P = 0.02) before and after adjustment for age, gender, residence and obesity-related traits. Conclusions The study suggested that the APOE genotype and haplotype significantly associated with plasma TC and LDL-C level in Vietnamese children. The association of APOE genotype with hypoalphalipoproteinemia was independent of obesity-related traits.

Abstract
Association of apolipoprotein E (APOE) ε4 allele with peripheral quantitative computed tomography (pQCT) bone traits at the distal and shaft sites of the radius and tibia was evaluated in the Young Finns Cohort (n=1777). We also analyzed the interactions of the APOE promoter polymorphisms (-219G/T rs405509 and +113G/C rs440446) and bone traits within the APOE ε3/ε3 genotype (n=1025 and n=1013, respectively), and investigated the gene-environment interactions on bone traits with longitudinal saturated fatty acids (SAFA) intake. Differences between the ε4 allele carriers and noncarriers were modest and mostly nonsignificant. Within the APOE promoter -219G/T polymorphism, cortical strength index (CSI) and compressive bone strength index (BSI) at the distal radius (linear, P=0.003 and P=0.05, respectively) and tibia (linear, P=0.01 and P=0.03, respectively), and CSI at the tibial shaft (linear, P=0.04) decreased towards the -219T/T genotype in women. In men, total cross-sectional areas at the radial site and stress-strain index (SSI) at the radial shaft (linear, P=0.03 and P=0.04 and P=0.05, respectively) increased, and conversely cortical bone density and CSI at the radial shaft (linear, P=0.005 and P=0.05, respectively) and CSI at the tibial shaft (linear, P=0.03) decreased towards the -219T/T genotype. In the highest SAFA tertile, women with the -219T/T genotype had the smallest total area and SSI at the radial shaft (P=0.01 and P=0.02, respectively). Subjects with the APOE +113C/C genotype shared similar bone traits as subjects with the APOE -219T/T genotype. In conclusion, APOE genotypes -219T/T and +113C/C could be genetic markers for cortical bone strength. Furthermore, high longitudinal SAFA intake seems to be more detrimental to bone in women with the -219T/T and +133C/C genotypes than others.

Abstract
Background Adiponectin links obesity with insulin resistance, which causes various metabolic abnormalities including dyslipidaemia. Apolipoprotein E (apoE) phenotypes also affect lipoprotein profiles. We aimed to determine whether low adiponectin concentrations are associated with insulin resistance and downstream metabolic abnormalities in obese children. Methods We measured fasting concentrations of lipids, apoE, glucose, insulin and adiponectin, as well as anthropometric parameters, in 191 obese children aged 6–15 years. ApoE phenotypes were determined by isoelectric focusing. Boys ( n = 79) and girls ( n = 39) with apoE3/3 were classified into tertiles according to their adiponectin concentrations. Metabolic parameters, were compared among these three groups in boys and girls separately. Results The low adiponectin groups had higher median homeostasis model assessment of insulin resistance (HOMA-IR) than the middle and high adiponectin groups in both boys [5.3 (low) versus 3.1 (middle; P < 0.05) and 3.5 (high; P < 0.05)] and girls [5.0 (low) versus 4.4 (middle) and 3.0 (high; P < 0.05)]. However, only boys who were in the low adiponectin group exhibited significantly higher concentrations of blood pressure, triglycerides, LDL-cholesterol, and remnant-like particle-cholesterol, and lower concentrations of HDL-cholesterol compared with the middle or high adiponectin groups. Conclusion Low adiponectin concentration is associated with insulin resistance in obese children. Furthermore, decreased adiponectin with E3/3 exhibited more prominent downstream metabolic abnormalities in obese boys than in obese girls.

Abstract
BACKGROUND We examined the influence of apolipoprotein E (apoE) polymorphism on longitudinal changes in serum lipids by following the subjects participating in The Cardiovascular Risk in Young Finns Study over a 21-year period. METHODS Serum lipids were determined in randomly selected Finnish children and adolescents in 1980 and the subjects were re-examined in 1983, 1986 and after 21 years in 2001. ApoE polymorphism was determined in 1736 participants, and serum lipid values and apoE phenotypes were available for 1233 subjects. RESULTS ApoE phenotype-related differences in serum total and low-density lipoprotein (LDL)-cholesterol were maintained throughout the 21-year follow-up from childhood to adulthood, i.e., the apoE epsilon2 allele was consistently associated with lower and the epsilon4 allele with higher total and LDL-cholesterol (p<0.001 for all). In adulthood, there was also a significant apoE phenotype-related difference in high-density lipoprotein (HDL)-cholesterol (p=0.007), and the epsilon2 allele was associated with higher and the epsilon4 allele with lower apoA-I and HDL-cholesterol. In addition, apoB increased in the phenotype order E3/2<E3/3<E4 (E4/3+E4/4) (p<0.001). The LDL-lowering effect of the epsilon2 allele was greater in adulthood than in childhood, i.e., there was a significant apoE phenotypextime interaction (p=0.039) with longitudinal change in LDL-cholesterol. CONCLUSIONS ApoE polymorphism is associated with lipid levels at different ages and affects the longitudinal change in LDL-cholesterol from childhood to adulthood.

Abstract
Recent gene-targeting technology has provided good animal models that provide insight into the pathology of complex diseases such as atherosclerosis. The apolipoprotein E gene polymorphism is one of the most extensively studied in cardiovascular medicine. The scope of the present review is to briefly outline the biochemical characteristics and the genetic variation of apolipoprotein E. Apolipoprotein E is best known for its role in modulating lipoprotein metabolism as a ligand for cellular receptors. Other functions unrelated to lipid transport are becoming known, including reverse cholesterol transport, immunoregulation and modulation of cell growth. This review will examine recent work that addresses how apolipoprotein E participates in atherosclerosis. Genotypic variation of apolipoprotein E has been associated with certain phenotypes regarding vascular disease, such as the presence of atherosclerosis and coronary heart disease outcomes. This article will also review evidence regarding the association between apolipoprotein E gene polymorphisms and coronary artery disease based upon experimental and clinical studies.

Abstract
Metabolic alterations are a key player involved in the onset of Alzheimer disease pathophysiology and, in this review, we focus on diet, metabolic rate, and neuronal size differences that have all been shown to play etiological and pathological roles in Alzheimer disease. Specifically, one of the earliest manifestations of brain metabolic depression in these patients is a sustained high caloric intake meaning that general diet is an important factor to take in account. Moreover, atrophy in the vasculature and a reduced glucose transporter activity for the vessels is also a common feature in Alzheimer disease. Finally, the overall size of neurons is larger in cases of Alzheimer disease than that of age-matched controls and, in individuals with Alzheimer disease, neuronal size inversely correlates with disease duration and positively associates with oxidative stress. Overall, clarifying cellular and molecular manifestations involved in metabolic alterations may contribute to a better understanding of early Alzheimer disease pathophysiology.

Abstract
Studies of gene-environment interactions aim to describe how genetic and environmental factors jointly influence the risk of developing a human disease. Gene-environment interactions can be described by using several models, which take into account the various ways in which genetic effects can be modified by environmental exposures, the number of levels of these exposures and the model on which the genetic effects are based. Choice of study design, sample size and genotyping technology influence the analysis and interpretation of observed gene-environment interactions. Current systems for reporting epidemiological studies make it difficult to assess whether the observed interactions are reproducible, so suggestions are made for improvements in this area.

Abstract
We investigated the frequency of apolipoprotein E (apoE) polymorphism and the effect of apoE polymorphism on plasma lipid and lipoprotein levels under different nutritional statuses in Vietnamese children living in urban and rural areas. Three hundred and forty-eight girls (aged 7 to 9 years) were randomly selected from urban and rural areas in southern Vietnam. Their apoE genotypes were analyzed by an Invader assay, and the plasma lipid and lipoprotein levels were determined by enzymatic methods using fasting blood samples. Dietary intake and anthropometry of children were also measured. The frequency of the allele epsilon 2 and epsilon 4 of the Vietnamese girls was 0.09 and 0.12, respectively. The levels of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) of the allele epsilon 2 carriers were significantly lower than those of the allele epsilon 3 carriers (P < .0001) in both the urban and rural groups. In contrast, the allele epsilon 4 carriers tended to show a higher LDL-C level than the allele epsilon 3 carriers, especially in subjects with a higher fat intake in urban area. The allele epsilon 2 carriers had the same high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) level as the allele epsilon 3 carriers, but the allele epsilon 4 carriers with a higher fat intake living in urban areas had lower HDL-C and higher TG level than allele epsilon 3 carriers. In conclusion, our findings showed that the LDL-C lowering effect of allele epsilon 2 was independent of the nutritional status, while allele epsilon 4 tended to lower HDL-C and increase the LDL-C level in a high-fat intake population. Therefore, the plasma lipid profiles of apoE epsilon 4 carriers may be a risk factor of atherogenesis in Vietnamese, who tend to have a westernized eating habit.

Abstract
The effects of dietary intervention, sex, and apolipoprotein E phenotype on tracking of serum lipid values in young children have remained poorly characterized. We investigated these associations in 1062 infants who were randomized into control and intervention groups (n=522 and n=540, respectively) at age 7 months; the intervention group received counseling aimed at maintaining a low-saturated fat, low-cholesterol diet. In 519 children in the control (n=254) and intervention (n=265) groups, serum lipid values were studied annually between 13 months and 5 years of age. In all children, tracking was strongest for the ratio of high density lipoprotein (HDL) cholesterol to total cholesterol; when a 13-month-old child belonged to the lowest quartile of the distribution, the odds ratio for belonging to the same quartile at older ages was 39.0 (95% CI 23.1 to 66.0). Dietary intervention did not influence the tracking of serum lipids. Tracking of HDL cholesterol was stronger in the boys than in the girls (P=0.018). Tracking of non-HDL cholesterol and apolipoprotein B in the children with phenotypes E2/3 or E3/3 was stronger than that in the other children (P=0.031 and P=0.014, respectively). In conclusion, the apolipoprotein E phenotype strongly influences tracking of non-HDL cholesterol and apolipoprotein B values in early childhood, whereas dietary intervention had no effect on tracking of any of the lipids. A child's sex influenced tracking only of HDL cholesterol, with boys showing stronger tracking.

Abstract
Research in the field of gene-diet interactions as determinants of plasma lipid response to dietary interventions has accumulated a substantial body of evidence during the past decade. Several candidate genes have shown some promise as potential markers of individual dietary responsiveness. Among the best characterized are the APOE, APOA4, APOB, APOC3, and LPL loci. Other genes are being continuously incorporated to this most interesting search. However, in very few cases has consensus been achieved about the usefulness of genetic markers as clinically significant predictors of dietary response. The increased ability to generate genotypic information, in combination with the knowledge from the human genome project and more comprehensive experimental designs, will dramatically improve our capacity to answer many of our current questions. It will also help to prove that knowledge of an individual's genetic background will facilitate more precise dietary counseling and intervention, and more efficacious primary and secondary coronary heart disease prevention.

Abstract
BACKGROUND The E4 allele of the apolipoprotein gene (APOE) is associated with a greater serum cholesterol response to dietary changes in fat and cholesterol. However, less is known about the interaction between APOE polymorphism and other macronutrients in the diet. OBJECTIVE We evaluated the interaction between APOE polymorphism and dietary fat and carbohydrate, particularly sucrose, in relation to serum lipid concentrations. DESIGN A total of 284 men and 130 women with coronary artery disease (mean age: 61 y; range: 33-74 y) participated in the cross-sectional EUROASPIRE study. Serum lipids and fatty acids in cholesteryl esters (CEs) were measured and APOE genotypes were determined. Dietary intake was examined by using a 4-d food record. RESULTS Patients were grouped by APOE genotype: E2 (E2/E2 and E2/E3; n = 21), E3 (E3/E3; n = 245), and E4 (E4/E2, E4/E3, and E4/E4; n = 148). Patients with the E2 allele had lower LDL-cholesterol concentrations and tended to have higher triacylglycerol concentrations than did patients with the E3 or E4 allele; concentrations were not significantly different between the last 2 groups. In regression analysis, significant predictors of serum triacylglycerol were the interaction between sucrose intake and the E2 allele, proportion of n-3 fatty acids in CEs, body mass index, and diabetes. A high sucrose intake was associated with high triacylglycerol concentrations only in patients with the E2 allele. Interaction between saturated fat intake and the E2 allele, proportion of linoleic acid in CEs, and fiber intake predicted serum cholesterol. CONCLUSION Coronary artery disease patients with the E2 allele will likely have a greater triacylglycerol response to high dietary sucrose intakes than will patients with the E3 or E4 allele.

Abstract
OBJECTIVE We examined associations between allelic variation in the apo epsilon gene, which codes for apolipoprotein E, and plasma lipid levels in children. MATERIALS AND METHODS We analyzed genotype and fasting lipid levels, including lipid particle size by nuclear magnetic resonance spectroscopy, in 515 children from 297 families. RESULTS Children carrying the apo epsilon2 allele (1 or 2 epsilon2 alleles; n = 45) had higher mean high-density lipoprotein (HDL) cholesterol level (49.5 +/- 13.0 vs 42.4 +/- 8.9 mg/dL) and lower mean low-density lipoprotein (LDL) cholesterol level (82.2 +/- 48.6 vs 105.9 +/- 45.0 mg/dL) compared with apo epsilon3/epsilon3 children (n = 322). Mean HDL size was larger and mean level of the atheroprotective large HDL subpopulation was higher among apo epsilon2 carriers compared with epsilon3/epsilon3 children (9.5 +/- 0.4 vs 9.3 +/-.4 nm, and 32.8 +/- 9.9 vs 27.6 +/- 8.2 mg/dL). In multivariate models adjusting for age, sex, ethnicity, family history, body mass index, and fasting triglyceride level, the apo epsilon2 allele was independently predictive of higher levels of HDL cholesterol and the large HDL subpopulation and of lower level of LDL cholesterol. CONCLUSION The apo epsilon2 allele is associated with an anti-atherogenic lipid pattern in children.apolipoprotein epsilon, children, cholesterol.

Abstract
BACKGROUND A genetically influenced atherogenic lipoprotein phenotype characterized by a predominance of small, dense LDL particles (subclass pattern B) can be induced by low-fat diets in healthy subjects with large LDL particles (pattern A). OBJECTIVE The aim of this study was to test whether genetic predisposition to subclass pattern B contributes to susceptibility to induction of this trait by a low-fat diet. DESIGN The prevalence of pattern B in children is relatively low compared with that in older individuals, but genetic susceptibility to this trait in offspring can be inferred by its presence in their parents. Plasma lipoproteins were analyzed 10 d after a change from a usual diet to a very-low-fat (10% fat), high-carbohydrate diet in offspring (mean age: 14 y; range: 7-28 y) of 22 families according to parental LDL-subclass patterns when consuming a low-fat diet: AxA mating (9 families with 19 children), AxB mating (5 families with 10 children), and BxB mating (8 families with 21 children). RESULTS The very-low-fat, high-carbohydrate diet produced significantly greater decreases in LDL particle size in offspring of BxB parents (f1.gif" BORDER="0"> +/- SE: -0.55 +/- 0.16 nm) and AxB parents (-0.48 +/- 0.19 nm) than in offspring of AxA parents (0.14 +/- 0.20 nm). The number of children expressing pattern B with the 10%-fat diet and the proportion of children converting from pattern A to pattern B was significantly greater in offspring of BxB parents than in those with 1 or 2 pattern A parents. CONCLUSION A very-low-fat, high-carbohydrate diet can induce expression of LDL-subclass pattern B in genetically predisposed children with low expression of the trait while consuming their usual diets.

Abstract
OBJECTIVES To determine the apolipoprotein E (apoE) allelic frequencies and the effect of apoE genotype on lipid concentrations in indigenous Australian subjects. DESIGN Cross-sectional study. SUBJECTS AND SETTING 155 indigenous Australians (92 women and 63 men) of mean (+/- standard deviation) age 45 +/- 17 years (SD +/- 50) were recruited without regard to history of atherosclerotic disease, in collaboration with community-based health centres in five indigenous communities in south-east Queensland. For comparison, 113 subjects of European descent and similar age distribution from the Brisbane and Gold Coast regions were also studied. MAIN OUTCOME MEASURES ApoE allelic frequency; apoE genotype; sex; age; diabetes status; body mass index; history of atherosclerotic vascular disease; and concentrations of total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol. RESULTS The frequency of the apoE4 allele was found to be significantly higher in the indigenous subjects than in the subjects of European descent (P < 0.001). Among indigenous subjects, those with the apoE4 allele tended to have higher triglyceride concentrations and had significantly lower HDL-cholesterol concentrations than those with the apoE3/3 and 3/2 genotypes. CONCLUSIONS ApoE allelic frequency is likely to be one of the cluster of factors contributing to the high cardiovascular mortality of indigenous Australians.

Abstract
CHD is a multifactorial disease that is associated with non-modifiable risk factors, such as age, gender and genetic background, and with modifiable risk factors, including elevated total cholesterol and LDL-cholesterol levels. Lifestyle modification should be the primary treatment for lowering cholesterol values. The modifications recommended include dietary changes, regular aerobic exercise, and normalization of body weight. The recommended dietary changes include restriction in the amount of total fat, saturated fat and cholesterol together with an increase in the consumption of complex carbohydrate and dietary fibre, especially water-soluble fibre. However, nutrition scientists continue to question the value of these universal concepts and the public health benefits of low-fat diets, and an intense debate has been conducted in the literature on whether to focus on reduction of total fat or to aim efforts primarily towards reducing the consumption of saturated and trans fats. Moreover, it is well known that there is a striking variability between subjects in the response of serum cholesterol to diet. Multiple studies have examined the gene-diet interactions in the response of plasma lipid concentrations to changes in dietary fat and/or cholesterol. These studies have focused on candidate genes known to play key roles in lipoprotein metabolism. Among the gene loci examined, APOE has been the most studied, and the current evidence suggests that this locus might be responsible for some of the inter-individual variability in dietary response. Other loci, including APOA4, APOA1, APOB, APOC3, LPL and CETP have also been found to account for some of the variability in the fasting and fed states.

Abstract
OBJECTIVES Lipid-lowering drugs as 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase inhibitors and cholestyramine are effective in reducing cardiovascular morbidity both in primary and secondary prevention. Patient compliance is an important determinant of the outcome of therapy. This study was designed to compare compliance with tolerance and lipid-lowering effectiveness of pravastatin and/or cholestyramine in primary care. DESIGN Nine hundred and eighty nine women and 1047 men were randomized to treatment at 100 primary-care centres in Sweden. After dietary intervention, an eligible patient was randomly assigned to one of four programs of daily treatment: group Q, 16 g cholestyramine, group QP, 8 g cholestyramine and 20 mg pravastatin, group P20, 20 mg pravastatin or group P40, 40 mg pravastatin. RESULTS In group Q, group QP, group P20 and group P40 the reductions in low density lipoprotein (LDL)-cholesterol were 26%, 36%, 27% and 32%. The dose actually taken was 91-95% of the prescribed for the pravastatin treatment groups and 77-88% for the cholestyramine groups. In the pravastatin and cholestyramine groups 76-78% and 44-53%, respectively, completed the trial. Only 8-27% of the patients reached a serum cholesterol target level of 5.2 mmol L-1. There was no difference in lipid-lowering effect between women and men. CONCLUSION Pravastatin alone is efficacious and compliance is high, independent of dose. Combined treatment with cholestyramine and pravastatin had a better cholesterol lowering effect (although not statistically significant) than 40 mg pravastatin. Despite this, only 8-27% of the patients actually reached a serum cholesterol level of 5.2 mmol L-1. No unexpected serious adverse events were detected in any of the treatment groups. As predicted, the gastrointestinal disturbances were more common on cholestyramine treatment. These two factors suggest that an increase in the dosage of the HMG-CoA reductase inhibitor may be appropriate. Results from other studies indicate that there also might be other positive effects of statin treatment beyond cholesterol lowering.

Abstract
Favourable changes in environment and lifestyle in the community may lead to a situation in which genetic determinants of ischaemic heart disease assume greater importance. Does this imply that ischaemic heart disease becomes more difficult to prevent? Much of the role of the family history as a risk factor within populations may be explained by new genetic mutations. However, differences between populations are generally attributable to environmental differences. A model of gene-environment interaction implies that individuals or populations with genetic risk markers are both more susceptible and more responsive to environmental changes, including lifestyle and drugs, and thus, may be eminently treatable.

Abstract
We studied 22 normal-weight patients with polygenic hypercholesterolemia (PH), of which 11 (two males and nine females) had the apolipoprotein (apo) E3/4 genotype and 11 (one male and 10 females) the E3/3 genotype. The two groups were comparable for age, body mass index, total and low-density lipoprotein (LDL) cholesterol levels. The diagnosis of PH was made on the basis of clinical assessment, the criteria being type IIa hypercholesterolemia without tendon xanthomas and/or family history and clinical criteria indicative of familial hypercholesterolemia and/or familial combined hyperlipidemia. To avoid the influence of the habitual individual diet on cholesterogenesis, daily urinary mevalonic acid (MVA) excretion, an index of whole-body cholesterol synthesis, was evaluated in the steady-state condition while patients were on a low-fat, low-cholesterol diet for at least 3 months. Urinary MVA excretion rates were 2.52 +/- 0.8 micromol/24 h in E3/4 patients, significantly higher (P < .001) than in E3/3 patients (1.38 +/- 0.6 micromol/24 h). This is the first evidence of a higher rate of cholesterogenesis in PH patients carrying the epsilon4 allele versus the epsilon3 allele under a standardized lipid-lowering diet. We conclude that the higher rate of cholesterogenesis in PH patients with the epsilon4 allele might partly explain the interindividual differences in response to treatment with cholesterol synthesis inhibitors such as statins.
