Abstract:

The effects of incubating J774 mouse macrophages with different fatty acids on cholesterol esterification were investigated. In cells incubated with n–3 polyunsaturated fatty acids, the rate of cholesterol esterification was significantly reduced compared with cells incubated with n–6 polyunsaturated fatty acids or with oleic acid. This change in cholesterol esterification appears to be the result of reductions in the activity of acyl-CoA:cholesterol acyltransferase (ACAT) in the endoplasmic reticulum of the macrophages incubated with the n–3 polyunsaturated fatty acids. No differences in microsomal cholesterol were observed among cells incubated with different fatty acids. However, cellular cholesterol levels were lower in cells incubated with n–3 polyunsaturated fatty acids. In microsomes from cells incubated with n–3 polyunsaturated fatty acids, both the Km and the Vmax of ACAT were lower than in microsomes from cells incubated with n–6 fatty acids or oleic acid. These findings may explain some of the reduction in atherosclerotic lesions that are observed with dietary fish oils that contain high levels of n–3 polyunsaturated fatty acids.Key words: n–3 polyunsaturated fatty acids, acyl-CoA:cholesterol acyltransferase, macrophages, cholesterol esterification.

Abstract:

Unsaturated fatty acids act a necessary part in the intestinal health of the host microbiota environment and immune ability by being transformed by intestinal microorganisms. Polyunsaturated fatty acids (PUFAs) are very important to the host body, also they influence many physiological activities of the body. The amount of polyunsaturated fatty acids synthesized by the human body cannot meet the daily needs of the human body, and it is necessary to obtain some essential fatty acids (EFA) from food. At the same time, some intestinal microorganisms can also synthesize and convert polyunsaturated fatty acids, which contribute to the regulation and control of host immunity. In addition, PUFAs are also beneficial to humans. They are critical in sustaining a healthy and stable gut microbiota environment and regulating and controlling host immunity. This paper summarized the conversion mechanism and effect of intestinal microbiota on polyunsaturated fatty acids, discussed whether polyunsaturated fatty acids can regulate human diseases and microbiota as health products, and determined the regulatory mechanism of polyunsaturated fatty acids.

Abstract:

The study aimed to examine, compare, and statistically evaluate the quality of the beef thigh and roast beef muscle in terms of the profile of fatty acids in relation to human health. Musculus semimembranosus and m. quadriceps femoris of the thigh and m. longissimus dorsi of the roast beef were used for analysis to evaluate the fatty acid profile. Chemical analysis of the thigh and roast beef muscle samples was performed using Fourier transform infrared (FTIR) spectroscopy. The measured data were statistically processed according to descriptive characteristics, analysis of variance, and differences were tested using Scheffe´s test at a = 0.05. The SAS program package, version 8.2, was used to evaluate the results statistically. A statistically significant difference (p ≤0.05) was recorded in the dry matter proportion between m. quadriceps femoris and m. longissimus dorsi. A statistically significant difference was found in the intramuscular fat proportion, polyunsaturated fatty acid proportion, the ratio of polyunsaturated fatty acids to saturated fatty acids, the ratio of polyunsaturated fatty acids to monounsaturated fatty acids, as well as between m. semimembranosus and m. longissimus dorsi and between m. quadriceps femoris and m. longissimus dorsi. Strong, statistically significant (p ≤0.01, p ≤0.001) correlations were found mainly between intramuscular fat and polyunsaturated fatty acids, between intramuscular fat and the ratio of the polyunsaturated fatty acids to saturated fatty acids, between intramuscular fat and the ratio of polyunsaturated fatty acids to monounsaturated fatty acids. In conclusion, it was stated that the muscles of the thigh and roast beef of the young cattle are characterized by statistically significant differences in the proportion of fatty acids. The ratio of polyunsaturated fatty acids to saturated fatty acids meets the recommended values concerning maintaining the health of the food consumer. Still, the ratio of the n-6 to n-3 polyunsaturated fatty acids poses a risk concerning cardiovascular diseases.

Abstract:

Age-related alterations of fatty acid composition in liver and brain of AKR mice was investigated. The effect of savory essential oil (Satureja hortensis L.), added with drinking water on fatty acid composition in these organs and the processes of lipid peroxidation in erythrocytes were estimated. It was found that during aging the percentage of saturated fatty acids and polyunsaturated fatty acids decreased while monounsaturated fatty acids increased. The development of leukemia was accompanied by the increase of saturated and polyunsaturated fatty acids percentage and a decrease of monounsaturated fatty acids amount. In the liver aging caused the increase in the percentage of saturated fatty acids, the decrease of monounsaturated fatty acids, while the amount of polyunsaturated fatty acids was not changed. Leukemia (after 8 month) was accompanied by the increase of percentage of monounsaturated fatty acids and the decrease in the amount of oleinic and docosohexaenic acids. The intake of savory essential oil was accompanied by intensification of polyunsaturated fatty acids synthesis in mice liver and reduction of lipid peroxidation products content.

Abstract:

Omega-3 polyunsaturated fatty acids and B vitamins are linked to metabolic and degenerative disorders, such as cardiovascular disease and cognitive decline. In the last two decades, the interplay between B vitamins and omega-3 polyunsaturated fatty acids gained increasing attention. Expression control on enzymes involved in the pathway of homocysteine by polyunsaturated fatty acids has been proposed. The methylation process seems crucial for the metabolism of polyunsaturated fatty acids and their distribution within the body. This review summarizes the available data in humans about the link between homocysteine and omega-3 polyunsaturated fatty acids, with a special focus on the meta-analyses of randomized clinical trials. Even if the paucity of available information about the topic does not allow for definitive conclusions, a synergic action between polyunsaturated fatty acids and B vitamins may play a key role in regulating several metabolic pathways. This element could explain a stronger action on homocysteine levels when omega-3 polyunsaturated fatty acids and B vitamins are supplemented simultaneously. To date, a robust rationale of intervention to prevent metabolic diseases is lacking and could be beneficial for individual health and healthcare policy.

Abstract:

Two groups of essential fatty acids (n-6 and n-3) are needed in a healthy human diet. Current advice suggests an optimal ratio of about 4:1 for these polyunsaturated fatty acids (PUFAs) in the diet but in Western countries it is usually 10-20:1. The n-3 PUFAs are synthesized in photosynthetic organisms from where they move up the food chain. Fish in particular, are a rich source of twenty and twenty two carbon n-3 PUFAs which are particularly effective for humans. Fish oils have been shown to be beneficial in a variety of chronic inflammatory diseases. However, fish stocks arc under threat. Therefore, fish farming has increased recently and offers some opportunities for viable sources of n-3 PUFAs, especially since disposal of fish farm waste is expensive and environmentally problematic. In this project, we investigated trout ( Oncorhynchus mykiss) as a potential source of n-3 PUFAs. The lipid composition of different tissues was analysed by combinations of TLC and GLC. This work identified the differences between various individual tissues and pin-pointed those with high eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) content. Two possible industrial lipid extraction methods were compared with a standard laboratory procedure. These studies included a comparison of yields for offal which had been stored for various times. The rendering method, although not as efficient as the laboratory procedure (Garbus), was concluded to allow oil yield for nutraceutical development although tissues could not be stored for greater than two days without compromised quality. Finally, oil extracts from trout (containing 2.5% EPA and 10.5% DHA) were tested in a model system (bovine cartilage explants) as treatment for osteoarthritis. The trout oil preparation significantly reduced cytokine-induced glycosaminoglycan release indicating a protective action. However, it was not as effective as pure EPA or DHA. Moreover, the trout oil preparation was not able to reduce mRNA levels of inflammatory genes (e.g., COX-2, IL-6, ADAMTS-4, -5 and MMP-3) which were lowered by pure EPA or DHA supplementation. We conclude that trout waste is a viable source of n-3 PUFAs for nutraceutical development but that processing will probably be needed to produce a dietary supplement with potent anti inflammatory properties.

Abstract:

In MS patients there was a significantly positive relationship between membrane AA and TGF-ß1 indicating that it is the individual long chain (LC) PUFA, i.e. AA that regulate the levels of TGF-ß1. Investigation of the effects of n-6 and n-3 PUFAs on normal healthy PBMC production of TGF-ß1 in vitro showed that PBMC in the presence of phytohaemaglutinin (PHA) supplemented with LA, dihyomo-?-linolenic (DGLA) and arachidonic acid (AA) significantly increase TGF-ß1 compared with non-supplemented PHA-stimulated PBMCs. In contrast, TGF-ß1 levels from PHA-stimulated PBMCs supplemented with a-linolenic (ALA), eicosapentaenoic (EPA) or docosahexaenoic acid (DHA) were significantly decreased suggesting that n-6 fatty acids (LA, DGLA and AA) increase in vitro TGF-ß1 production by PHA-stimulated PBMCs and, in contrast, n-3 fatty acids (ALA, EPA and DHA) decrease TGF-ß1 production. GLA-rich borage oil supplementation resulted in significantly decreased ex vivo monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1a (MIP-1a) and interleukin-8 (IL-8) production from PHA-or LPS-stimulated PBMC compared with baseline. It also significantly decreased cell surface expression of CD36+, CD54+ and CD62L+ on monocytes. In contrast, there was no association between LA-rich corn oil and these adhesion molecules and chemokines suggesting that GLA and/or its metabolites are affecting the chemokines and adhesion molecules studied. Overall, results of this study indicate that n-6 long chain PUFAs may have anti-inflammatory properties and might therefore be beneficial in multiple sclerosis, atherosclerosis and other inflammatory diseases.

Abstract:

A transplantable murine colon adenocarcinoma (MAC16) was utilised as a model of human cancer cachexia. This tumour has been found to produce extensive weight loss, characterised by depletion of host body protein and lipid stores at a small tumour burden. This weight loss has been found to be associated with production by the tumour of a lipolytic factor, activity of which was inhibited in vitro by the polyunsaturated fatty acid (PUFA) eicosapentaenoic acid (EPA). EPA has also been shown to possess anti-tumour and anti-cachectic activity in vivo, leading to the hypothesis that fatty acids mobilised by the lipolytic factor supply a growth requirement of the MAC16 tumour. In this study mobilisation and sequestration of fatty acids by the tumour was found to be non-specific, although a relationship between weight loss and arachidonic acid (AA) concentration was found in both tumour-bearing mice, and human cancer patients. The anti-tumour effect of EPA, which was found to be associated with an increase in cell loss, but not its anti-cachectic activity, was reversed by the administration of the PUFAs oleic acid (OA) and linoleic acid (LA). LA was also found to be capable of stimulating tumour growth. Inhibition of either the cyclooxygenase or lipoxygenase pathways was found to result in reduction of tumour growth, leading to the implication of one of the metabolites of LA or AA in tumour growth and cachexia. The ethyl ester of EPA was found to be inactive against the growth and cachexia of the MAC16 tumour, due to its retarded uptake compared with the free acid. The anti-proliferative agent 5-fluorouracil was found to cause tumour growth inhibition, and when given in combination with EPA, reduced the phase of tumour regrowth observed after 4 to 5 days of treatment with EPA.

Abstract:

Voltage-gated ion channels play fundamental roles in neuronal excitability and therefore dysfunctional channels can cause disease. Epilepsy is such a disease, affecting about 1% of the population and being characterized by synchronous electric activity of large groups of neurons leading to various types of seizures. In this thesis, polyunsaturated fatty acids (PUFAs) were used as key substances to study a new pharmacological mechanism for how to induce opening of voltage-gated potassium (Kv) channels, and how this possibly can protect against epileptic activity. All experiments were performed on cloned Shaker Kv channels expressed in Xenopus laevis oocytes. Channel activity was recorded with the electrophysiological two-electrode voltage clamp technique. First we showed that both PUFAs and cerebrospinal fluid from children on the ketogenic diet open the Shaker Kv channel by shifting the channel voltage dependence towards more negative voltages, as we would expect for an antiepileptic effect. By testing fatty acids and related compounds with different properties and under different conditions we identified the critical structural components needed for the beneficial effect: a flexible cis-polyunsaturated lipid tail in combination with a negatively charged carboxyl head group. If substituting the negative charge for a positive amine group, channel opening was instead impeded. By mutating and modifying the channel at strategic positions the PUFA-action site was localized to a lipid-exposed surface close to the channel’s voltage sensor. We also showed that PUFAs induce channel opening by electrostatically facilitating a final voltage-sensor movement. The PUFA efficiency is dependent on the channel’s profile of charged residues in the outer end of the voltage sensor. This implies channel-specific effects. Finally, computer simulations demonstrated that small changes in channel voltage dependence can have dramatic effects on cellular excitability. Both the identified PUFA-action site and the mechanism by which PUFAs induce channel opening are novel and could potentially be very useful in future drug design of compounds targeting neuronal and cardiac excitability. Our work also suggests that PUFA-induced Kv channel opening could be one important component in the ketogenic diet used as alternative epilepsy treatment.

Abstract:

Polyunsaturated Fatty Acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are increasingly attracting scientific attention due to their significant health promoting role in the human body. However, the human body lacks the ability to produce them in vivo. The limitations associated with the current sources of ω-3 fatty acids and ω-6 fatty acids from animal and plant sources have led to increased interest in microbial production. Marine bacteria provide a suitable alternative, although the isolation of production strains and the identification of operating conditions must be addressed before manufacturing processes become economically viable. Sea sediment samples were collected from three different environments including Mid Atlantic Ridge, Red Sea and Mediterranean Sea. The isolates were screened for PUFA production using a fast colourimetric method and verified by gas chromatography/mass spectroscopy. The isolated PUFA producers were characterised and identified on the basis of 16S rRNA gene sequencing and analysis. Three different isolates were chosen for this study. These were labelled as 717, 66 and Hus-27. The chosen isolates were subjected to an optimisation study to maximise their productivity. This optimisation strategy included identifying a suitable production medium by applying a statistical design of experiment methodology (Plackett-Burman and Central Composite Design). A chemically defined media was identified for isolates 717 and 66 in order to determine the limiting media components and to study the effect of carbon/nitrogen ratio on the productivity of isolates. As an important step in the process development of the microbial PUFA production, the culture conditions at the bioreactor scale were optimised for isolate 717 using a Response Surface Methodology (RSM) revealing the significant effect of temperature, dissolved oxygen and the interaction between them on the EPA production. Two sets of continuous stirred-tank reactor (CSTR) experiments were also performed to test the effect of growth rates on EPA production and the effect of temperature at constant growth rate as this was identified as the most significant factor affecting EPA production. This optimisation strategy led to a significant increase in the amount of EPA produced by isolates under investigation, where the amount of EPA increased from 9 mg/g biomass, 33 mg/l representing 7.6% of the total fatty acids to 45 mg/g, 350 mg/l representing 25% of the total fatty acids using isolate 717. A significant increase was also achieved using isolate 66 with the amount of EPA increased from 5.5 mg/g, 14 mg/l representing 3.5% of the total fatty acids to 32 mg/g, 285 mg/l representing 15% of the total fatty acids. For isolate Hus-27 the amount of EPA increased from 0.6 mg/g, 3 mg/l representing 2.2% of the total fatty acids to 8 mg/g, 36 mg/l representing 8% of the total fatty acids. The stability of the produced oil and the complete absence of heavy metals in bacterial biomass are considered as an additional benefit of bacterial EPA compared to other sources of PUFA. To our knowledge this is the first report of a bacterial isolate producing EPA with such high yields making large scale manufacture much more economically viable.

Abstract:

Pre-treatment with polyunsaturated fatty acids or bioactive lipid mediators has been shown to reduce neuronal injury in rodent models of focal ischaemia, but the molecular mechanisms underlying this neuroprotection are unclear. In this study, we aimed to investigate whether systemic administration of alpha linolenic acid (ALA) leads to changes in the profile of mouse brain phospholipid and bioactive lipid mediators in both mouse brain and plasma within the previously determined neuroprotection time window. Mass spectrometry (MS) and tandem mass spectrometry (MS/MS) allowed us to detect and identify 47 phospholipids in mouse cerebral cortex, including several phospholipid species not previously reported in brain lipidomic studies. These included a phosphatidylethanolamine species with m/z 720 that has been associated with retinal stem cells. No widespread changes in cerebral cortex phospholipid composition were observed following intravenous ALA. Several significant changes in lipid mediators (P<0.05 with two-way ANOVA and post hoc Dunnett's t test) were detected in ALA-treated animals compared to untreated and vehicle-injected animals. Many of the affected lipid mediators are ligands for prostanoid receptors which have been demonstrated to play a role in the development of brain injury following cerebral ischaemia, implying that changes in bioactive lipid mediators or modulation of prostanoid receptors may occur following ALA pre-treatment in mice. This study illustrates the potential of advanced lipidomic analysis as a novel tool for neurochemists.

Abstract:

Fish oils with a high content of polyunsaturated fatty acids (PUFAs) are gaining increasing interest in the food and nutraceutical industry, due to their important functional properties for human beings� health improvement. The most important PUFAs have at least two double bonds placed on the carbon chain. These include ?-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahaxaneoic acid (DHA). Microencapsulation is a technique used to protect the bioactive compounds from oxidative damage, to ensure their controlled release and to activate the synergistic effect of the ingredients, if it exists. In this context, the microencapsulation process of fish oils rich in PUFAs using alginate was studied, in the presence and the absence of an ultrasonic (US) field. Both BoxBehnken design of experiment technique and the Response Surface Method were used, to investigate the influence of the process parameters and to optimize the operating conditions. The operating parameters under investigation were the sodium alginate to fish oil ratio, the calcium chloride concentration and time being the objective. The fish oil microspheres had a homogeneous round shape, a diameter of 0.12 � 0.02 mm. Physicochemical description of microcapsules was performed using modern characterization methods.

Abstract:

The aim of this study was to analyze the properties of cold pressed pumpkin and walnut oil. Pumpkin and walnut are plant crops that have a long tradition of cultivation in Serbia, but are insufficiently used for oil production. Cold pressed oils have a high nutritional and market value. The production of cold-pressed oils is more environmentally friendly, simpler, and the oils retain important nutrients, compared to producing oils by extraction and refining. Pumpkin seed oil is characterized by a high content of polyunsaturated fatty acids in relation to the content of monounsaturated and saturated fatty acids. The dominant fatty acid is oleic or linoleic. Oils with a higher proportion of oleic acid are more oxidatively stable. Specifically, pumpkin oil is dominated by the presence of ∆7 sterols, unlike other vegetable oils. Walnut oil is dominated by polyunsaturated fatty acids, with a significant amount of C18:3, which makes it sensitive to oxidation. The oxidative stability of walnut oil is correlated with a decrease in the content of C18:3 fatty acids. The chemical composition of the oil varies significantly depending on the variety and growing conditions in both pumpkin and walnuts. then there is a potential in the determination of suitable genotypes with oil of greater oxidative stability.

Abstract:

Various unicellular algae produce omega-3 (w3) very-long-chain polyunsaturated fatty acids (VLC-PUFA), which are rarely found in higher plants. In this research and other studies from our laboratories, it has been demonstrated that the marine unicellular alga Nannochloropsis (Eustigmatophyceae) can be used as a reliable and high quality source for the w3 VLC-PUFA eicosapentaenoic acid (EPA). This alga is widely used in mariculture systems as the primary component of the artificial food chain in fish larvae production, mainly due to its high EPA content. Furthermore, w3 fatty acids are essential for humans as dietary supplements and may have therapeutic benefits. The goal of this research proposal was to understand the physiological and biochemical mechanisms which regulate the synthesis and accumulation of glycerolipids enriched with w3 VLC-PUFA in Nannochloropsis. The results of our studies demonstrate various aspects of lipid synthesis and its regulation in the alga: 1. Variations in lipid class composition imposed by various environmental conditions were determined with special emphasis on the relative abundance of the molecular species of triacylglycerol (TAG) and monogalactosyl diacylglycerol (MGDG). 2. The relationships between the cellular content of major glycerolipids (TAG and MGDG) and the enzymes involved in their synthesis were studied. The results suggested the importance of UDP-galactose diacylglycerol galactosyl (UDGT) in regulation of the cellular level of MGDG. In a current effort we have purified UDGT several hundredfold from Nannochloropsis. It is our aim to purify this enzyme to near homogeneity and to produce antibodies against this enzyme in order to provide the tools for elucidation of the biochemical mechanisms that regulate this enzyme and carbon allocation into galactolipids. 3. Our in vitro and in vivo labeling studies indicated the possibility that phosphatidylcholine (PC) and phosphatidylethanolamine (PE) are associated with desaturation of the structural lipids, whereas shorter chain saturated fatty acids are more likely to be incorporated into TAG. 4. Isolation of several putative mutants of Nannochloropsis which appear to have different lipid and fatty acid compositions than the wild type; a mutant of a special importance that is devoid of EPA was fully characterized. In addition, we could demonstrate the feasibility of Nannochloropsis biomass production for aquaculture and human health: 1) We demonstrated in semi-industrial scale the feasibility of mass production of Nannochloropsis biomass in collaboration with the algae plant NBT in Eilat; 2) Nutritional studies verified the importance algal w3 fatty acids for the development of rats and demonstrated that Nannochloropsis biomass fed to pregnant and lactating rats can benefit their offspring.
