Animals (Basel) 2023; 13:ani13091501. [PMID: 37174538 PMCID: PMC10177204 DOI: 10.3390/ani13091501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 04/14/2023] [Accepted: 04/26/2023] [Indexed: 05/15/2023] Open
Abstract
Taurine is a sulphur-containing amino acid with important physiological roles and a key compound for the synthesis of bile salts, which are essential for the emulsion and absorption of dietary lipids. This study aimed to evaluate the effects of taurine supplementation to low-fishmeal diets on the metabolism of taurine, bile acids, and lipids of Senegalese sole. A fishmeal (FM) and a plant-protein-based (PP0) diet were formulated, and the latter was supplemented with taurine at 0.5 and 1.5% (diets PP0.5 and PP1.5). Diets were assigned to triplicate tanks containing 35 fish (initial weight ~14 g) for 6 weeks. Fish from the PP0 treatment presented lower taurine and bile-acid concentrations compared with the FM treatment, and a downregulation of cyp7a1 and abcb11 was observed. Triolein catabolism decreased in PP0-fed fish, resulting in increased hepatic fat content and plasma triglycerides, while no effects on plasma cholesterol were observed. Taurine supplementation to plant-based diets resulted in a higher taurine accumulation in fish tissues, increased bile-acid concentration, and upregulation of cyp7a1 and abcb11. Hepatic fat content and plasma triglycerides decreased with increasing dietary taurine supplementation. Taurine supplementation mitigated part of the negative effects of plant-based diets, leading to better lipid utilisation.

Abstract
Marine fish larvae often experience high mortality unrelated to predation during early life stages, and farmed ballan wrasse (Labrus bergylta) is no exception. Knowing when the adaptive immune system is developed and fully functional, and how nutrition may modulate these processes is therefore of importance to establish effective prophylactic measures and will also extend the relatively limited knowledge on the immune system in lower vertebrates. The thymus anlage of ballan wrasse was found to be histologically visible for the first time at larval stage 3 (20-30 days post hatch, dph) and becomes lymphoid at stage 5 (50-60 dph) correlating with an increase of T-cell marker transcripts. At this stage, a clear zonation into a RAG1+ cortex and a RAG1- CD3ϵ+ medulla was distinguished, indicating that T-cell maturation processes in ballan wrasse are similar to other teleosts. The higher abundance of CD4-1+ compared to CD8β+ cells in the thymus together with the apparent lack of CD8β+ cells in gill, gut, and pharynx, where CD4-1+ cells were identified, indicates that helper T-cells have a more prominent role during larval development compared to cytotoxic T-cells. As ballan wrasse lacks a stomach but has an exceptionally high IgM expression in the hindgut, we hypothesize that helper T-cells are crucial for activation and recruitment of IgM+ B-cells and possibly other leukocytes to the gut during early development. Nutritional factors such as DHA/EPA, Zn and Se may lead to an earlier expression of certain T-cell markers as well as a larger size of the thymus, indicating an earlier onset of adaptive immunity. Including live feeds that supplies the larva with higher amounts of these nutrients can therefore be beneficial for ballan wrasse farming.

Abstract
In the present study, we assessed the therapeutic potential of Biochanin-A (BCA) (10 mg/kg BW/day) pretreatment for 30 days on lipid metabolic abnormalities, proinflammatory cytokines and matrix metalloproteinase expression in isoproterenol (ISO)-induced myocardial infarction (MI) in rats. We measured the potential role of BCA on tissue and circulatory lipid profiles as well as on lipid metabolic enzymes: serum inflammatory cytokines (TNF-α, IL-1α, IL-1β, IL-6 and MCP1) and serum Matrix Metalloproteinases (particularly, MMP-2 and MMP-9) together with mRNA expressions of TNF-α, IL-6, MMP-2 and MMP-9 by RT-PCR analysis. Administration of ISO to rats significantly distorted their lipid metabolism and augmented inflammatory process, MMP expression and proteolytic activity. In addition, pretreatment with BCA of ISO-induced MI rats significantly reestablished the altered lipid metabolism and concealed the inflammation of cytokines. BCA suppressed the expressions of proinflammatory cytokines and MMPs in ISO-induced MI in rats when compared to normal untreated MI rats. Hence, these results established that BCA could improve the pathological processes of myocardial remodeling which was confirmed by histopathology of heart in MI rats and might be an effective beneficial ingredient for the management of heart failure disorders.

Abstract
The present study demonstrated the protective effects of arbutin (ARB) on hyperlipidemia, mitochondrial, and lysosomal membrane damage and on the DNA damage in rats with isoproterenol (ISO)-induced myocardial infarction (MI). Rats were pretreated with ARB (25 and 50 mg/kg body weight (bw)) for 21 days. After pretreatment with ARB, MI was induced by subcutaneous injection of ISO (60 mg/kg bw) for two consecutive days at an interval of 24 h. The levels of TC, TG, and FFA were increased and decreased the level of PL in the heart tissue of ISO-induced MI rats. Very-low-density lipoprotein cholesterol and low-density lipoprotein cholesterol were increased while high-density lipoprotein cholesterol was decreased in the plasma of ISO-administered rats. A heart mitochondrial fraction of the ISO rats showed a significant decrease in the activities of mitochondrial enzymes isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, succinate dehydrogenase, and malate dehydrogenase. The activities of lysosomal enzymes (β-glucosidase, β-glucuronidase, α-galactosidase, β-galactosidase, cathepsin-B, and cathepsin-D) were increased significantly in the heart tissue homogenate of disease control rats. In ISO-induced MI, rat’s significant increase in the percentage of tail DNA and tail length, and a decrease in the level of head DNA were also observed. ARB administration to MI rats brought all these parameters to near normality, showing the protective effect of ARB against MI in rats. The results of this study demonstrated that the 50 mg/kg bw of ARB shows higher protection than 25 mg/kg bw against ISO-induced damage.

Abstract
Taurine (TAU) plays important roles in the metabolism of bile acids, cholesterol and lipids. However, little relevant information has been available in fish where TAU has been identified as a conditionally essential nutrient. The present study aimed to investigate the effects of dietary TAU on the metabolism of bile acids, cholesterol and lipids in tiger puffer, which is both an important aquaculture species and a good research model, having a unique lipid storage pattern. An 8-week feeding trial was conducted in a flow-through seawater system. Three experimental diets differed only in TAU level, that is, 1·7, 8·2 and 14·0 mg/kg. TAU supplementation increased the total bile acid content in liver but decreased the content in serum. TAU supplementation also increased the contents of total cholesterol and HDL-cholesterol in both liver and serum. The hepatic bile acid profile mainly includes taurocholic acid (94·48 %), taurochenodeoxycholic acid (4·17 %) and taurodeoxycholic acid (1·35 %), and the contents of all these conjugated bile acids were increased by dietary TAU. The hepatic lipidomics analysis showed that TAU tended to decrease the abundance of individual phospholipids and increase those of some individual TAG and ceramides. The hepatic mRNA expression study showed that TAU stimulated the biosynthesis of both bile acids and cholesterol, possibly via regulation of farnesoid X receptor and HDL metabolism. TAU also stimulated the hepatic expression of lipogenic genes. In conclusion, dietary TAU stimulated the hepatic biosynthesis of both bile acids and cholesterol and tended to regulate lipid metabolism in multiple ways.

Abstract
In this study, a near infrared (NIR) spectroscopy fingerprinting method coupled with principal component analysis (PCA) was developed for the confirmation of brand identification in infant formulas. The NIR spectroscopy fingerprints of the Brand A infant formula were acquired in 12 000-4000 cm-1 at a sample temperature of 20 °C without pressing the sample. The contents of major nutrients of Stage 1, 2, and 3 infant formulas were compared within Brand A. The NIR spectroscopy fingerprints of Brand A Stage 1 samples were compared with those of four other brand-named Stage 1 samples, whereas the fingerprints of Brand A Stage 2 and 3 were compared with those of two of the four brands, to distinguish the differences between brands. The NIR spectroscopy fingerprinting results showed that the Brand A formula can be completely differentiated from the other brands at each stage. The combination of NIR spectroscopy fingerprinting and PCA is an effective method for the purpose of confirmation of brand identification and brand protection in infant formulas.

Abstract
Currently, hepatic injury due to environmental pollutants extremely threatens human health and elicits great concern. Hence, there is a high global interest to find natural novel formulation products with potent hepatoprotective activity to combat liver disease. Hence, we evaluated the protective or therapeutic effect of hesperidin (HSP) and taurine (TAU), individually and in combination, on carbon tetrachloride (CCl4)-induced acute hepatic injury in rats. The pre- or posttreatment by HSP and/or TAU significantly depressed CCl4-induced elevation of alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, gamma-glutamyl transferase, total bilirubin, direct bilirubin, indirect bilirubin, malondialdehyde, globulins (α1, α2, β, and γ), albumin/globulin ratio, triglycerides, total cholesterol, high-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, low-density lipoprotein cholesterol, nitric oxide, and myeloperoxidase levels. Also, the pre- or posttreatment by HSP and/or TAU significantly minimized CCl4-induced reduction of superoxide dismutase, catalase, reduced glutathione, and albumin concentrations. Furthermore, the protective or therapeutic administration of HSP and/or TAU markedly restored the CCl4-induced altered hepatic architecture, depleted glycogen, and DNA contents. Notably, alleviating CCl4-induced hepatotoxicity was more prominent in the protective groups than the therapeutic groups. More importantly, most of biochemical and histopathological parameters of HSP+TAU did not significantly differ from those of separate TAU or HSP neither before nor after CCl4 exposure. Conclusively, HSP or TAU could be candidate protective agents against CCl4 hepatotoxic impacts but the combination of both bioactive offers only a limited synergistic effect. Graphical abstract.

Abstract
The effects of four different extraction methods (Folch, Soxhlet, two-step, and enzyme-assisted aqueous extraction) on the yields, lipid class, fatty acids (FAs) composition, minor components (including carotenoid, cholesterol), and thiobarbituric acid reactive substances values of lipids in the hepatopancreas of Chinese mitten crab (Eriocheir sinensis) were investigated. The C16:0, C18:1, and C18:2 were identified to be the dominant FAs in crab lipids, and the FAs were present in the form of triglycerides. The Soxhlet and enzyme-assisted extraction were more suitable for crab lipids extraction, showing higher extraction rates and oxidative stability. Especially, the lipid extracted by enzyme-assisted extraction has high carotenoids content. The components of crab lipids extracted by enzyme-assisted aqueous extraction were further identified using untargeted metabolomics methods. The polyunsaturated fatty acid, sterols, amino acids, products of lipid β-oxidation and ATP degradation, phosphatidyl ethanolamine, and astaxanthin were founded in crab oil. PRACTICAL APPLICATION: The Chinese mitten crab (Eriocheir sinensis) is a popular aquatic food in China. The hepatopancreas is the major lipid storage organ of crab, and the distinctive flavor of crab is mainly from it. To compare the different extraction methods on yield, composition and properties of crab lipids can be helpful for lipids production from crab hepatopancreas. Meanwhile, the crab hepatopancreas lipids are rich in polyunsaturated fatty acids and astaxanthin, and have potential to be as a functional component and a crab flavor additive in food industry.

Abstract
The present study aims to investigate the hepatoprotective effect of taurine (TAU) alone or in combination with silymarin (SIL) on CCl4-induced liver damage. Twenty five male rats were randomized into 5 groups: normal control (vehicle treated), toxin control (CCl4 treated), CCl4+TAU, CCl4+SIL and CCl4+TAU+SIL. CCl4 provoked significant increases in the levels of hepatic TBARS, NO and NOS compared to control group, but the levels of endogenous antioxidants such as SOD, GPx, GR, GST and GSH were significantly decreased. Serum pro-inflammatory and fibrogenic cytokines including TNF-α, TGF-β1, IL-6, leptin and resistin were increased while the anti-inflammatory (adiponectin) cytokine was decreased in all treated rats. Our results also showed that CCl4 induced an increase in liver injury parameters like serum ALT, AST, ALP, GGT and bilirubin. In addition, a significant increase in liver tissue hydroxyproline (a major component of collagen) was detected in rats exposed to CCl4. Moreover, the concentrations of serum TG, TC, HDL-C, LDL-C, VLDL-C and FFA were significantly increased by CCl4. Both TAU and SIL (i.e., antioxidants) post-treatments were effectively able to relieve most of the above mentioned imbalances. However, the combination therapy was more effective than single applications in reducing TBARS levels, NO production, hydroxyproline content in fibrotic liver and the activity of serum GGT. Combined treatment (but not TAU- or SIL-alone) was also able to effectively prevent CCl4-induced decrease in adiponectin serum levels. Of note, the combined post-treatment with TAU+SIL (but not monotherapy) normalized serum FFA in CCl4-treated rats. The biochemical results were confirmed by histological and ultrastructural changes as compared to CCl4-poisoned rats. Therefore, on the basis of our work, TAU may be used in combination with SIL as an additional adjunct therapy to cure liver diseases such as fibrosis, cirrhosis and viral hepatitis.

Abstract
The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were conducted in order to identify the underlying factors for this phenomenon. In the first experiment (Exp-1), groups of cod larvae were fed either (a) natural zooplankton, mainly copepods, increasing the size of prey as the larvae grew or (b) enriched rotifers followed by Artemia (the intensive group). In the second experiment (Exp-2), two groups of larvae were fed as in Exp-1, while a third group was fed copepod nauplii (approximately the size of rotifers) throughout the larval stage. In both experiments, growth was not significantly different between the groups during the first three weeks after hatching, but from the last part of the rotifer feeding period and onwards, the growth of the larvae fed copepods was higher than that of the intensive group. In Exp-2, the growth was similar between the two copepod groups during the expeimental period, indicating that nutrient composition, not prey size caused the better growth on copepods. Analyses of the prey showed that total fatty acid composition and the ratio of phospholipids to total lipids was slightly different in the prey organisms, and that protein, taurine, astaxanthin and zinc were lower on a dry weight basis in rotifers than in copepods. Other measured nutrients as DHA, all analysed vitamins, manganese, copper and selenium were similar or higher in the rotifers. When compared to the present knowledge on nutrient requirements, protein and taurine appeared to be the most likely limiting nutrients for growth in cod larvae fed rotifers and Artemia. Larvae fed rotifers/Artemia had a higher whole body lipid content than larvae fed copepods at the end of the experiment (stage 5) after the fish had been fed the same formulated diet for approximately 2 weeks.

Abstract
The health of Skeena River Sockeye salmon (Onchorhychus nerka) has been of increasing concern due to declining stock returns over the past decade. In the present work, in-migrating Sockeye from the 2008 run were evaluated using a mass spectrometry-based, targeted metabolomics platform. Our objectives were to (a) investigate natural changes in a subset of the hepatic metabolome arising from migration-associated changes in osmoregulation, locomotion, and gametogenesis, and (b) compare the resultant profiles with animals displaying altered hepatic vitellogenin A (vtg) expression at the spawning grounds, which was previously hypothesized as a marker of xenobiotic exposure. Of 203 metabolites monitored, 95 were consistently observed in Sockeye salmon livers and over half of these changed significantly during in-migration. Among the most dramatic changes in both sexes were a decrease in concentrations of taurine (a major organic osmolyte), carnitine (involved in fatty acid transport), and two major polyunsaturated fatty acids (eicosapentaenoic acid and docosahexaenoic acid). In females, an increase in amino acids was attributed to protein catabolism associated with vitellogenesis. Animals with atypical vtg mRNA expression demonstrated unusual hepatic amino acid, fatty acid, taurine, and carnitine profiles. The cause of these molecular perturbations remains unclear, but may include xenobiotic exposure, natural senescence, and/or interindividual variability. These data provide a benchmark for further investigation into the long-term health of migrating Skeena Sockeye.

Abstract
One of the many functions of taurine is to protect cells against oxidation, by protecting mitochondrial integrity and respiration. Taurine metabolism has attracted much attention in fish nutrition due to the fact that as plant ingredients replace fishmeal, dietary taurine has declined. As the endogenous synthesis of taurine might be too low to protect cells against oxidative stress and apoptosis, the present study aimed to test whether taurine may protect liver cells from apoptosis. Liver cells isolated from Atlantic salmon (Salmo salar) were grown in media supplemented with a physiological concentration of taurine (25 (se0·5) mm) or without any taurine supplementation (14 (se3) μm) for 3 d. To increase oxidation in the mitochondria and maximise any cellular response of taurine supplementation, 100 μm-CdCl2was added or not added to the cells at day 3. At day 4, cells were harvested and assessed for viability. As expected, the addition of CdCl2decreased cell viability without showing any interaction with taurine supplementation. Cells grown in the taurine-supplemented media had lower protein abundance of active caspase-3. In addition, the protein abundance of phosphorylated mitogen-activating phosphokinase (P-p63, P-p42/44 and P-p38) as well as cytochrome P450 were reduced when taurine was added to the media. Cells grown without taurine supplementation had a more condensed chromatin and more smeared DNA, also pointing to a higher apoptosis in these cells. In conclusion, taurine attenuated apoptosis in primary liver cells isolated from Atlantic salmon, and as such, taurine may be conditionally indispensable in Atlantic salmon.

Abstract
This study investigates the antihyperlipidemic effect of ursolic acid (UA) on isoproterenol (ISO) induced male albino Wistar rats. Myocardial ischemia was induced by subcutaneous injection of ISO (85 mg/kg BW) twice at an interval of 24 h, for two consecutive days. A significant increase in the activities of the serum marker enzymes [creatine kinase, creatine kinase-MB and lactate dehydrogenease (LDH)], a prominent expression of LDH 1 and LDH 2 isoenzymes, increased levels of plasma total cholesterol (TC), low density lipoprotein-cholesterol, very low density lipoprotein-cholesterol, triglycerides (TG), free fatty acids (FFA), phospholipids (PL) and atherogenic index and decreased level of high density lipoprotein-cholesterol were observed in ISO-induced rats. The levels of TC, TG and FFA increased and the level of PL decreased in the heart tissue of ISO-induced rats. Further, there was an increased DNA damage (Comet assay) and myocardium infarct size as observed by staining with triphenyltetrazolium chloride (TTC). UA was administered subcutaneously for 7 days at a dose of 40 mg/kg BW. UA administration to ischemic rats brought all these parameters to near normality showing the protective effect of UA on ISO-induced rats.

Abstract
BACKGROUND Taurine (2-aminoethanesulfonic acid) is a semi-essential amino acid found in mammalian tissues that is not involved in protein synthesis. The function of taurine is not completely understood. Some studies have demonstrated that taurine supplementation reduces death rate in rabbits with heart failure (HF) and diminishes HF severity in human models of congestive HF. In this study we have evaluated the effect of taurine supplementation on exercise capacity of patients with HF. METHODS A randomized single-blind placebo-controlled clinical trial was conducted on 29 patients with HF with left ventricular ejection fraction (LVEF) less than 50% who were in functional class II or III according to New York Heart Association classification. A total of 15 patients received taurine supplementation 500 mg three times a day while the remaining 14 patients received placebo for 2 weeks. All patients performed exercise tolerance test before and after taurine and placebo supplementation. RESULTS The mean age of patients was 60.57 ± 6.54 years, they were mostly male (26 of 29), and had mean LVEF of 29.27 ± 6.97%. There were no significant differences in terms of LVEF, body mass index, and also exercise time, metabolic equivalents (METS) and exercise distance before supplementation. Exercise time, METS, and exercise distance increased significantly in patients who received taurine supplement for 2 weeks (p-value<0.0001 for all), but did not increase significantly in patients who received placebo (p-values 0.379, 0.244, and 0.577 respectively). CONCLUSION Taurine supplementation in patients with HF who are taking standard medical treatment can increase their exercise capacity.

Abstract
This study was designed to evaluate the hypocholesterolemic effects of masou salmon 70% ethanol extract (MSE) and to determine the molecular mechanism by which MSE exerts its effects in high-fat (HF) diet-induced obese mice. We hypothesize that the MSE may contain abundant n-3 fatty acids, so a diet containing MSE may also have hypolipidemic effects by assessing several key gene expressions in cholesterol metabolism such as the low-density lipoprotein (LDL) receptor, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, and cholesterol 7alpha-hydroxylase (CYP7A1). To test this hypothesis, C57BL/6J mice were fed a 40% HF diet for 5 weeks, after which time the animals were fed an HF diet containing 0 mg/kg, 75 mg/kg, or 150 mg/kg MSE (HF, HF + MSE 1, and HF + MSE 2 groups, respectively) for an additional 4 weeks (n = 8 in each group, for a total of 24 mice). We found that feeding MSE with an HF diet prevented hypercholesterolemia in diet-induced obese mice; daily MSE feeding reduced total cholesterol levels in plasma and liver by 12.3% and 16.2%, respectively. Furthermore, we examined the expression of key cholesterol metabolism genes by reverse transcription-polymerase chain reaction and found that messenger RNA levels of HMG-CoA reductase were decreased by up to 5-fold, but the expression of both LDL receptor and CYP7A1 did not change. Thus, MSE may exert its hypocholesterolemic effect by altering the expression of HMG-CoA reductase.

Abstract
The clawed lobsters Homarus gammarus and Homarus americanus are high-priced and appreciated food items in southern Europe. From a nutritional point of view there is still limited information on the chemical composition of edible tissues (muscle, hepatopancreas, and gonads) of both species. Therefore, the aims of the present work were to study the proximate chemical composition, energy, fatty acid and amino acid profiles, and cholesterol content in each edible tissue of both species and to evaluate their nutritional quality. Differences were observed between tissues, sexes, and species. Muscle and gonads were rich in protein, whereas hepatopancreas had high fat, cholesterol, and energy contents. All edible tissues were valuable sources of essential amino acids. Contrary to the common belief that shellfish consumption should be reduced in a low-fat and -cholesterol diet, all edible tissues of clawed lobsters have a nutritious value perfectly compatible with nutritious and healthy diets.
