Lipids And Lipoproteins

Relationships between nutrient intakes and plasma lipids and lipoproteins were studied in 1,669 schoolchildren, aged 6 to 19 years; 948 were selected by random recall and 721 because of elevated plasma cholesterol or triglyceride (hyperlipidemic recall). Nutrient intake data was collected by using a 24-hour dietary recall. Median dietary cholesterol intakes for 6 to 9-year-old boys and girls in the random recall group were 222 and 230 mg/day, with polyunsaturated/saturated fat ratios of 0.34 and 0.33. For boys and girls, aged 10 to 12 years, median dietary cholesterol intakes were 296 and 235 mg/day, for 13 to 15 year olds, 343 and 237, and for 16 to 19 year olds, 418 and 221 mg/day. The dietary polyunsaturated/saturated fat ratios did not change appreciably with age. Partial correlation coefficients describing relationships between lipids, lipoproteins, and nutrients after adjustment for age, sex, race, and Quetelet index (W/H2) were calculated for all children (random and hyperlipidemic recall) after excluding children having plasma cholesterol, triglycerides, and calories less than or equal to the first or greater than or equal to the 99th percentiles for the random recall children. Plasma cholesterol was inversely and triglyceride positively correlated with dietary sucrose. Plasma low density lipoprotein cholesterol was inversely correlated with the dietary polyunsaturated/saturated fat ratio, total carbohydrate, and sugar. Potential relationships between nutrients and lipids-lipoproteins were also examined in children having low (first to tenth percentile), intermediate (45th to 55th percentile), and high (90th to 99th percentile) nutrient intake, after covariance adjustment for age, race, sex, and Quetelet index. Total plasma cholesterol fell as sucrose intake increased. Triglyceride rose along with caloric intake, total carbohydrate intake, and sucrose intake, while high density lipoprotein cholesterol levels fell with increasing caloric and sucrose intake. As dietary polyun-saturate ingestion rose from low to intermediate to high, plasma low density lipoprotein cholesterol increased. Nutrient intake may play a small but significant role relative to lipids and lipoproteins in children and, as such, may have importance relative to pediatric precursors of atherosclerosis.

The study was conducted to investigate the effects of copper (Cu) sources and levels on mineral utilization, tissue copper residues, and lipid metabolism in Arbor Acres broilers. A total of 640 male broilers were randomly divided into 5 groups with 8 replicates per group and 16 broilers per replicate. The experiment was used in a 2 × 2 + 1 factorial experiment design. Broilers in the control group were fed a basal diet, and animals in the other four groups were fed basal diets supplemented with Cu from copper sulphate and copper methionine. Copper concentrations of the experimental diets were 20 and 40 mg Cu/kg dry matter. A metabolism trial of 4 days was conducted during the last week of experimental feeding. Neither Cu source nor Cu level affected average daily gain, average daily feed intake or feed gain ratio (P > 0.05). Broilers fed 40 mg Cu/kg diets had lower plasma cholesterol than those in the control group (P < 0.05). Copper supplementation decreased (P < 0.05) plasma low-density lipoprotein cholesterol but did not alter plasma high-density lipoprotein cholesterol concentrations or plasma triglyceride concentrations. Copper sulphate supplementation increased (P < 0.05) liver Cu but did not alter pectorals Cu, heart Cu, tibia Cu and tibia P. Broilers fed 40 mg/kg Cu from copper sulphate had a lower (P < 0.05) tibia Ca level. The concentration of liver Cu in the broilers fed copper methionine diets was higher (P < 0.05) than that in those fed copper sulphate. Compared with copper sulphate (100%), the relative bioavailability value of copper methionine was 117%. In conclusion, the relative bioavailability of copper methionine obtained in this study was greater than that of copper sulphate. Copper plays an important role in plasma lipids and in the digestion of dietary Ca in broiler chickens.

Plasma And Liver Lipids

The aim of the present study was to measure the effect of graded inclusion of baked beans (Phaseolus vulgaris) on plasma and liver lipids in hypercholesterolaemic pigs fed on a Western-type diet. Twenty- four Large White × Landrace pigs of about 30 kg body weight were made hypercholesterolaemic by feeding a semi-purified diet, high in saturated fat and supplemented with 10 g cholesterol/kg, for 14 d. After that, six pigs were randomly assigned to one of the four experimental groups. They received their respective diets, containing 0, 100, 200 or 300 g baked beans/kg, on a dry-matter basis, for a further 28 d. Fasting blood samples were taken and analysed for total plasma cholesterol, lipoproteins and triacylglycerols. After the pigs were slaughtered at the end of the study, livers were analysed for their cholesterol content. Consumption of baked beans at 100, 200 and 300 g/kg reduced plasma total cholesterol by 5·3, 20·2 and 35·6 % respectively. However, only the diet with 300 g baked beans/kg showed a significant reduction (P < 0·05) compared with the control (without baked beans)- The level of low-density-Hpoprotein-cholesterol was also significantly (P < 0·05) reduced by 48% at 300 g baked beans/kg. Plasma very-low-density-lipoprotein-cholesterol, high-density-lipoprotein-cholesterol and triacylgiycerol contents were not affected by bean consumption. The supplements of 200 and 300 g baked beans/kg promoted a significant (P < 0·05) reduction of about 50% in cholesterol deposition in the liver, compared with the control.

1. Plasma lipids and lipoproteins have been studied in control subjects and patients with various types of steatorrhoea. 2. Low plasma cholesterol levels were found in malabsorbers and were associated with decreased amounts of low-density lipoprotein (LDL) in males and high-density lipoprotein (HDL) in females. 3. Serum triglyceride levels were normal in males, but exceeded control values in some of the females, due to an increase in very-low-density lipoprotein. 4. LDL composition was abnormal in both male and female malabsorbers, with a decreased proportion of cholesterol ester and an increased proportion of triglyceride. There was also an increased proportion of triglyceride in HDL. 5. These findings show that malabsorption markedly influences not only the concentration but also the composition of plasma lipoproteins.

Objective: Familial hypercholesterolemia (FH) is a dominant inherited disease caused mainly by low-density lipoprotein receptor (LDLR) gene mutations. To different extents, both heterozygous and homozygous FH patients develop premature coronary heart disease (CHD). However, most of the experimental animal models with LDLR deficiency could not fully recapitulate FH because they develop hyperlipidemia and atherosclerosis only in homozygous, but not in heterozygous, form. In the current study, we investigated the responsiveness of the LDLR+/− hamster to dietary cholesterol and whether plasma cholesterol levels were positively associated with the severity of atherosclerosis. Approach and Methods: wild type WT and LDLR+/− hamsters were fed a high fat diet with different cholesterol contents (HCHF) for 12 or 16 weeks. Plasma lipids, (apo)lipoproteins, and atherosclerosis in both the aorta and coronary arteries were analyzed. After a HCHF diet challenge, the levels of total cholesterol (TC) in WT and LDLR+/− hamsters were significantly elevated, but the latter showed a more pronounced lipoprotein profile, with higher cholesterol levels that were positively correlated with dietary cholesterol contents. The LDLR+/− hamsters also showed accelerated atherosclerotic lesions in the aorta and coronary arteries, whereas only mild aortic lesions were observed in WT hamsters. Conclusions: Our findings demonstrate that, unlike other rodent animals, the levels of plasma cholesterol in hamsters can be significantly modulated by the intervention of dietary cholesterol, which were closely associated with severity of atherosclerosis in LDLR+/− hamsters, suggesting that the LDLR+/− hamster is an ideal animal model for FH and has great potential in the study of FH and atherosclerosis-related CHD.

Debate exists as to whether improvements in some cardiometabolic risk factors following exercise training result more from the last session of, or from an accumulation of, exercise sessions. This study was designed to compare the effect of a single exercise session with 3 consecutive days of exercise on triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C). Twelve young adult (aged 22.5 ± 2.5 years), overweight (body mass index = 29.7 ± 4 kg·m–2), sedentary, black (n = 5) and white (n = 7) men (n = 6) and women (n = 6) completed, in random order, a single treadmill exercise session at 60% maximal oxygen uptake for 90 min (1EX), accumulated exercise sessions (same as for 1EX) for 3 consecutive days (3EX), and a control protocol (no exercise for 6 days). Plasma samples were collected from baseline through 24, 48, and 72 h postexercise. Significant treatment-by-time interactions (p < 0.05) existed in HDL-C and LDL-C. Postexercise responses of HDL-C differed at 48 h (1EX: –3.6, 3EX: + 3.7 mg·dL−1) and 72 h (1EX: –1.7, 3EX: + 3.2 mg·dL−1). LDL-C responses differed at 48 h (1EX: –16, 3EX: + 6 mg·dL−1). Although not statistically significant, TG concentrations decreased by 29% at 24 h after 3EX, compared with –7% after 1EX. An inverse relationship between baseline and postexercise reduction in TG was present with 3EX (r = –0.655; p < 0.05). In conclusion, 3EX increased HDL-C and decreased TG more than 1EX, while the decrease in LDL-C after 1EX was suppressed. Blood lipid panel changes may be due to more accumulated effects over time rather than just a result of the most recent exercise session.

Tisochrysis Lutea

Long-chain polyunsaturated fatty acids n-3 series and especially docosahexaenoic acid are known to exert preventive effects on metabolic disturbances associated with obesity and decrease cardiovascular disease risk. n-3 LC-PUFAs are mainly consumed in the form of fish oil, while other sources, such as certain microalgae, may contain a high content of these fatty acids. The aim of this study was to evaluate the effects of Tisochrysis lutea (Tiso), a microalga rich in DHA, on metabolic disorders associated with obesity. Three male Wistar rat groups were submitted for eight weeks to a standard diet or high-fat and high fructose diet (HF), supplemented or not with 12% of T. lutea (HF-Tiso). The supplementation did not affect plasma alanine aminotransferase (ALAT). Bodyweight, glycemia and insulinemia decreased in HF-Tiso rats (ANOVA, p < 0.001), while total plasma cholesterol, high-density lipoprotein-cholesterol (HDL-C) increased (ANOVA, p < 0.001) without change of low-density lipoprotein-cholesterol (LDL-C) and triacylglycerol (TAG) levels. Tiso supplementation decreased fat mass and leptinemia as well as liver TAG, cholesterol and plasma tumor necrosis factor-alpha levels (ANOVA, p < 0.001) while it did not affect interleukin 6 (IL-6), IL-4 and lipopolysaccharides levels. HF-Tiso rats showed an increase of IL-10 level in abdominal adipose tissue (ANOVA, p < 0.001). In conclusion, these results indicated that DHA-rich T. lutea might be beneficial for the prevention of obesity and improvement of lipid and glucose metabolism.

The Impact

We examined the impact of APOE genotype on plasma lipids and glucose in a secondary analysis of data from a five-arm, randomised controlled, parallel dietary intervention trial (‘RISCK’ study), to investigate the impact of replacing saturated fatty acids (SFA) with either monounsaturated fat (MUFA) or carbohydrate of high or low glycaemic index (GI) on CVD risk factors and insulin sensitivity. We tested the impact of APOE genotype (carriage of E2 and E4 alleles versus E3/E3), determined retrospectively, on plasma lipids, lipoproteins and glucose homeostasis at baseline (n = 469), and on the change in these variables after 24 weeks of dietary intervention (n = 389). At baseline, carriers of E2 (n = 70), E4 (n = 125) and E3/E3 (n = 274) expressed marked differences in total plasma cholesterol (TC, p = 0.001), low density lipoprotein cholesterol (LDL-C, p < 0.0001), apolipoprotein B (apo B, p < 0.0001) and total to high density lipoprotein cholesterol ratio (TC:HDL-C, p = 0.002), with plasma concentrations decreasing in the order E4 > E3/E3 > E2. Following intervention, there was evidence of a significant diet x genotype interaction with significantly greater decreases in TC (p = 0.02) and apo B (p = 0.006) among carriers of E4 when SFA was replaced with low GI carbohydrate on a lower fat diet (TC −0.28 mmol/L p = 0.03; apo B −0.1 g/L p = 0.02), and a relative increase in TC (in comparison to E3/E3) when SFA was replaced with MUFA and high GI carbohydrates (TC 0.3 mmol/L, p = 0.03). Among carriers of E2 (compared with E3/E3) there was an increase in triacylglycerol (TAG) when SFA was replaced with MUFA and low GI carbohydrates 0.46 mmol/L p = 0.001). There were no significant interactions between APOE genotype and diet for changes in indices of glucose homeostasis. In conclusion, variations in APOE genotype led to differential effects on the lipid response to the replacement of SFA with MUFA and low GI carbohydrates.

This study was designed to assess "tracking" of plasma cholesterol, triglyceride, and high and low density lipoprotein cholesterol (C-HDL, C-LDL), in 108 children followed over a four-year period in the Cincinnati Lipid Research Clinic's Princeton School study. The correlations between initial and subsequent measurements of plasma cholesterol were respectively 0.65, 0.66, and 0.68 for observations one, two, and three years apart, P &lt; .001; for plasma triglyceride they were 0.47, 0.37, and 0.39, P &lt; .001. Initial and subsequent C-HDL and C-LDL levels were also highly correlated, r = .60, .53 (for C-HDL), r = .67 and .61 (for C-LDL), for observations two and three years apart, P &lt; .001. Six of 13 children initially in the top decile for plasma cholesterol remained there over the four-year period. Only three of 11 children initially in the top decile for plasma triglyceride remained there over the four-year period. Plasma C-HDL levels initially in the top decile generally remained there, with 82% and 64% of children initially in the top decile remaining in the top two deciles on follow-up. Plasma C-LDL levels were more dispersed than C-HDL, with three of 11 children initially in the top decile remaining there after four years. A considerable proportion of the decrement in group mean levels of lipids and lipoproteins for children initially in the top deciles could be accounted for by regression toward the mean. Although initial and subsequent measures of lipids and lipoproteins in school children are closely correlated, and there is a moderate degree of tracking for children initially in the top deciles, only small numbers of children after four years of follow-up will retain persistent elevations of cholesterol, triglyceride, and C-LDL. Longitudinal assessment of children with elevated lipid and lipoprotein levels may permit early identification of risk factors which both increase risk to coronary heart disease in adulthood (cholesterol, triglyceride, C-LDL), or decrease it (C-HDL).

High plasma cholesterol levels are found in several metabolic disorders and their reductions are advocated to reduce risk of atherosclerosis. A way to lower plasma lipids is to curtail lipoprotein assembly and secretion; however, this is associated with steatosis. We have shown that microRNA-30c (miR-30c) reduces Western diet-induced hypercholesterolemia and atherosclerosis in C57BL/6J and Apoe -/- mice with no obvious adverse effects by reducing hepatic lipoprotein production and lipid synthesis. Here, we tested the effect of miR-30c on plasma lipids, transaminases and hepatic lipids in five different mouse models. Hepatic delivery of miR-30c reduced MTP activity but did not affect plasma cholesterol, triglyceride and glucose in chow-fed C57Bl6J and streptozotocin-induced diabetic, normolipidemic mice. However, hepatic delivery of miR-30c to chow fed leptin deficient ( ob/ob ) and leptin receptor deficient ( db/db ) hypercholesterolemic and hyperglycemic type 2 diabetic mice reduced cholesterol in total plasma and VLDL/LDL by ~ 28%and ~ 25%, respectively, without affecting phospholipid, triglyceride and glucose levels. Interestingly, these mice had lower plasma transaminases and creatine kinases indicating possible beneficial effects. Mechanistic studies showed that miR-30c reduced hepatic MTP activity and lipid synthesis. Moreover, miR-30c significantly lowered plasma cholesterol and atherosclerosis in Western-diet fed low density lipoprotein receptor knockout mice with no effect on plasma triglyceride, glucose and transaminases, suggesting that miR-30c can be a potential therapeutic agent for homozygous familial hypercholesterolemia. In all these studies, hepatic lipid levels were similar in control and miR-30c injected mice. These studies indicate that miR-30c reduces plasma cholesterol in diet-induced and diabetic hyperholesterolemic mice but not in normocholesterolemic mice. Thus, miR-30c may be beneficial in lowering plasma cholesterol in different metabolic disorders independent of the origin of hypercholesterolemia.
