Conjugated linoleic acids (CLA) affect atherogenesis, but mechanisms are not well understood. We explored how two isomers of CLA, cis9, trans11‐CLA and trans10, cis12‐CLA, affected lipid and glucose metabolism, as well as hepatic protein expression, in apolipoprotein E knockout mice. After 12 wk of intervention, plasma triglyceride, NEFA, and glucose concentrations were significantly higher in the trans10, cis12‐CLA group, whereas plasma triglyceride, NEFA, glucose, and insulin concentrations were significantly lower in the cis9, trans 11‐CLA group, compared with control mice consuming linoleic acid. Proteomics identified significant up‐ or down‐regulation of 113 liver cytosolic proteins by either CLA isomer. Principal component analysis revealed that the treatment effect of cis9, trans11‐CLA was mainly explained by the up‐regulation of different posttranslational forms of heat shock protein 70 kD. In contrast, the treatment effect of trans10, cis12‐CLA was mainly explained by up‐regulation of key enzymes in the gluconeogenic, β‐oxidation, and ketogenesic pathways. Correlation analysis again emphasized the divergent effects of both CLA isomers on different pathways, but also revealed a linkage between insulin resistance and increased levels of hepatic serotransferrin. Thus, our systems biology approach provided novel insights into the mechanisms by which individual CLA isomers differentially affect pathways related to atherogenesis, such as insulin resistance and inflammation.

Trans-10, cis-12-conjugated linoleic acid (CLA)-enriched diets promote fatty liver in mice, while cis-9, trans-11-CLA ameliorates this effect, suggesting regulation of multiple genes. To test this hypothesis, apoE-deficient mice were fed a Western-type diet enriched with linoleic acid isomers, and their hepatic gene expression was analyzed with DNA microarrays. To provide an initial screening of candidate genes, only 12 with remarkably modified expression between both CLA isomers were considered and confirmed by quantitative RT-PCR. Additionally mRNA expression of 15 genes involved in lipid metabolism was also studied. Ten genes (Fsp27, Aqp4, Cd36, Ly6d, Scd1, Hsd3b5, Syt1, Cyp7b1, and Tff3) showed significant associations among their expressions and the degree of hepatic steatosis. Their involvement was also analyzed in other models of steatosis. In hyperhomocysteinemic mice lacking Cbs gene, only Fsp27, Cd36, Scd1, Syt1, and Hsd3b5 hepatic expressions were associated with steatosis. In apoE-deficient mice consuming olive-enriched diet displaying reduction of the fatty liver, only Fsp27 and Syt1 expressions were found associated. Using this strategy, we have shown that expression of these genes is highly associated with hepatic steatosis in a genetic disease such as Cbs deficiency and in two common situations such as Western diets containing CLA isomers or a Mediterranean-type diet. Conclusion: The results highlight new processes involved in lipid handling in liver and will help to understand the complex human pathology providing new proteins and new strategies to cope with hepatic steatosis.

The generation by genetic engineering of two murine models to investigate atherosclerosis, such as the apoE- and LDLr- deficient mice, is providing an extraordinaire knowledge of the effect of different nutrients on this complex disease. The present revision provides a comprehensive overview of the advances in this field that point to a remarkable complexity. While some controversies over puzzling results could be explained invoking potential nutrient interactions or different food sources of nutrients, it also appears that other factors such as sex, genetic background or immunological status are emerging as generators of differential responses to nutrients during the atherosclerotic process.

ApoA-IV is a protein constituent of HDL particles; the gene coding for it is a member of the ApoA-I-ApoC-III-ApoA-IV cluster. To investigate the effects of the quantity and the degree of saturation of dietary lipid on the long-term response of this Apo, and on the hypothetical coordinated regulation of the cluster in vivo, pigs were fed isoenergetic, cholesterol-free, low-lipid or lipid-enriched diets (containing either extra olive oil (rich in MUFA) or sunflower oil (rich in n-6 PUFA)) for 42 d. In animals fed on the control diet, ApoA-IV was mainly associated with plasma lipoproteins. An increase in plasma ApoA-IV concentration, mainly in the lipoprotein-free fraction, was induced by the lipid-enriched diets, independent of the degree of saturation of the fatty acids involved. The latter diets also led to increases in hepatic ApoA-I, ApoA-IV and ApoC-III mRNA levels, more so with the sunflower oil-rich diet. The present results show that porcine plasma ApoA-IV levels and their association with lipoproteins are very sensitive to increases in dietary lipids, independent of the degree of fatty acid saturation. Furthermore, hepatic expression of RNA appears to be coordinated along with that of the other members of the gene cluster.

Background Hyperhomocysteinemia and hypoalphalipoproteinemia are two well-reported risk factors for cardiovascular disease. The effects of the synergistic combination of these two factors on vascular function need to be investigated. Methods and results Four groups of male mice were used: a control wild-type group; a group of mice heterozygous for cystathionine β-synthase deficiency; a group of mice heterozygous for apolipoprotein A-I deficiency; and, finally, a group of double heterozygous mice, with both cystathionine β-synthase and apolipoprotein A-I deficiency. To characterize the resulting phenotype, several parameters including plasma apolipoproteins, lipid profiles, homocysteine, blood pressure and aortic protein were analyzed. As expected, our results indicate that double heterozygous mice are a model of mild hypoalphalipoproteinemia and hyperhomocysteinemia. Further, the additive combination of both risk factors resulted in a significant increase in blood pressure compared with control animals (136 ± 8.0 versus 126 ± 7.5 mm Hg, P < 0.01) that was not present in single heterozygous mice. The increase in blood pressure was associated with decreased plasma nitric oxide levels, left ventricle hypertrophy and was independent of low-density lipoprotein (LDL) cholesterol, para-oxonase activity and kidney histological changes. Concomitant decreases in levels of apolipoprotein A-IV (APOA-IV) and caveolin-1 content were also found in the double heterozygous group. Conclusions Our findings suggest an additive adverse effect of hypoalphalipoproteinemia and hyperhomocysteinemia on endothelial function to generate clinical hypertension and cardiac muscle hypertrophy mediated by dysregulation in nitric oxide metabolism.

Double heterozygous mice lacking one allele of Cbs and Apoa1 develop hyperhomocysteinemia and hypoalphalipoproteinemia together with moderate hypertension. To study the influence of the genetic background into this specific phenotype, four groups of male mice were established: control and double heterozygous groups in C57BL/6J and in C57BL/6J x 129 backgrounds, respectively. Nitric oxide levels, systolic blood pressure, plasma lipid parameters, arylesterase activity and aorta histology were analyzed as well as oligonucleotide array hybridization of liver RNA. Results demonstrated that double heterozygous mice in C57BL/6J substrate had a milder phenotype showing lower increase in blood pressure compared to double heterozygous group in hybrid background. The severity of the phenotype in the latter group was associated with lower nitric oxide and arylesterase activity levels, and hyperplasia of the vascular media layer. Hepatic profiling of both genetic substrates showed profound differences in expression of contractile proteins that could explain these pathological findings. In summary, the phenotypic presentation of hypertension is associated with multiple processes from vascular bedside to liver as evidenced by nitric oxide production or paraoxonase levels.

Olive Oil Cultivars and Atherosclerotic Protection in Apolipoprotein E-knockout Mice

José M. Arbonés-Mainar; Jesús Osada

Publisher Summary The Mediterranean diet is associated with a reduction in all causes of mortality despite the high intake of fat, mainly derived from olive oil. Extra virgin olive oil, as a fruit juice, is a complex mixture where triglycerides are combined with other biologically active substances such as tocopherols, phenolic compounds, phytosterols, and triterpenoids, some of which have antioxidant and anti-inflammatory activities. The current view proposes that these components might be responsible for the benefits of virgin olive oil in animal models and in human studies. Extra virgin olive oil (EVOO) from different cultivars has subtle differences in fatty acids and minor components, which therefore are a source of variability worthy of being considered and tested regarding the anti-atherogenic properties of EVOO. Interactions among its components and diets should be also examined using experimental models. The apoE-deficient mouse develops spontaneous atherosclerosis on a regular low-fat/low-cholesterol diet. The progression and histopathology of lesions in this model show similar features to those observed in humans and other species. This chapter aims to investigate the effects of a Western diet (WD, high fat, high cholesterol) enriched either with an EVOO of different cultivars or with palm oil on serum lipids, lipoproteins, and the development of atherosclerosis in apoE-deficient mice.
