PURPOSE: This study examined the effect of soy proteins with depletion of different subunits of the two major storage proteins, β-conglycinin and glycinin, on hepatic lipids and proteins involved in lipid metabolism in rats, since the bioactive component of soy responsible for lipid-lowering is unclear. METHODS: Weanling Sprague Dawley rats were fed diets containing either 20% casein protein in the absence (casein) or presence (casein + ISF) of isoflavones or 20% alcohol-washed soy protein isolate (SPI) or 20% soy protein concentrates derived from a conventional (Haro) or 2 soybean lines lacking the α' subunit of β-conglycinin and the A1-3 (1TF) or A1-5 (1a) subunits of glycinin...

Calcitonin gene-related peptide (CGRP) is a bioactive peptide produced by alternative splicing of the primary transcript of the calcitonin/CGRP gene. CGRP is largely distributed in the cardiovascular and nervous systems, where it acts as a regulatory factor. CGRP is also expressed in organs and tissues involved in metabolic regulation, including white adipose tissue (WAT), where its function is largely unknown. In this study, we examined the effects of endogenous CGRP on metabolic function. When we administered a high-fat diet to CGRP knockout (CGRP-/-) and wild-type (WT) mice for 10 weeks, we observed that food intake did not differ between the two groups, but body weight and visceral fat weight were significantly lower in CGRP-/- mice...

Bombesin receptor subtype 3 (BRS-3) is an orphan G-protein-coupled receptor. Based on the obese phenotype of male BRS-3-deficient mice, BRS-3 has been considered an attractive target for obesity treatment. Here, we developed a novel selective BRS-3 agonist (Compound-A) and evaluated its anti-obesity effects. Compound-A showed anorectic effects and enhanced energy expenditure in diet-induced obese (DIO)-F344 rats. Moreover, repeated oral administration of Compound-A for 7 days resulted in a significant body weight reduction in DIO-F344 rats...

Chronic exposure to diets high in saturated fat (HFD) increases the prevalence of obesity and contributes to the development of low-grade inflammation and insulin resistance. A possible mediator accounting for obesity-associated inflammation and insulin resistance is Toll-like receptor 4 (TLR4). We investigated the role of adipocyte TLR4 in lipid and glucose homeostasis through an inducible, adipocyte-specific deletion of TLR4, the "TADIPO mouse". Consistent with a critical role for inflammation as a positive force for healthy adipose tissue expansion, chronic HFD exposure resulted in exacerbated whole body and muscle insulin resistance in the absence of TLR4 in the adipocyte...

Background: Asian subjects are at increased cardio-metabolic risk at comparatively lower BMI compared with Caucasians. Sympathetic nervous system activation and dyslipidaemia, both characteristics of increased adiposity, appear to be related. We therefore analysed the association of muscle sympathetic nerve activity (MSNA) with the plasma lipidomic profile in young Asian and Caucasian subjects. Methods: Blood samples were collected from 101 participants of either Asian or Caucasian background, aged 18-30, BMI 28...

The first 1000 days of life is marked by intense metabolic activity and tissue deposition. The increased nutritional needs during this period, and the challenges to meeting them, are often not understood or appreciated. Here, we describe the nutritional needs during the first 1000 days, highlight the challenges to meeting these needs in developing countries, outline intervention strategies, and examine the consumption of small-quantity lipid-based nutrient supplements (SQ-LNS) as a promising strategy. In low-income settings, the challenge to meeting nutritional needs during the first 1000 days is worsened by overreliance on cereal-based diets of low nutrient density and high prevalence of infections and infestations...

SCOPE: Sofrito, a key component of the Mediterranean diet, provides nutritional interest due to its high content in bioactive compounds from tomato and olive oil, and especially to the lipid matrix in which these compounds are found. In this study, the potential beneficial effects of dietary intake of sofrito on obesity-related vascular alterations were explored in obese Zucker rats. METHODS AND RESULTS: Obese and lean rats were fed a control diet supplemented or not with 2% (w/w) sofrito for 8 weeks...

High-fat diet-induced obesity is a major risk factor for osteoarthritis (OA) and diminished wound healing. The objective of this study was to determine the associations among serum and synovial fluid lipid levels with OA, synovitis, adipokine levels, and wound healing in a pre-clinical obese mouse model of OA. Male C57BL/6 J mice were fed either a low-fat (10% kcal) or one of three high-fat (HF, 60% kcal) diets rich in saturated fatty acids (SFAs), ω-6 or ω-3 polyunsaturated FAs (PUFAs). OA was induced by destabilization of the medial meniscus...

Pulmonary arterial hypertension (PAH) syndrome in broilers is associated with hypoxia, which prevails at high altitude. Oxidative stress is the pathogenic mechanism underlying PAH. Because selenium is key element in the structure of antioxidant enzymes, we evaluated pulmonary hypertensive responses in broiler chickens fed with diets supplemented with organic or nano-selenium. One hundred forty-four broilers (starting at 5 days old) were fed with (i) control group: birds received a standard diet; (ii) nano-selenium group: birds were fed with basal diet supplemented with nano-selenium at 0...

Brittle stars (Ophiura spp.) and other benthic macrofauna were collected in a prospective mariculture area in the North Sea to determine if these taxa could be used as indicator species to track nutrients released from future offshore aquaculture sites. We analysed natural carbon and nitrogen stable isotopic signatures in tissues from macrofauna and compared these to six feed ingredients and four experimental diets made thereof, as well as to a commercial feed with and without lipid and carbonate removal. Our data suggest practicability of using isotopic signatures of Ophiura spp...

BACKGROUND In clinics, patients with type 2 diabetes complicated with non-alcoholic fatty liver disease (NAFLD) have been shown to receive significant improvements in blood glucose levels, lipid levels, and liver function after sitagliptin treatment, although the mechanism of drug action remains poorly understood. This study investigated the possible mechanism of sitagliptin on lipid metabolism of NAFLD mice. MATERIAL AND METHODS Male C57/BL6 mice were induced for NAFLD via 16 weeks of a high-fat diet, and were treated with 15 mg/kg/day sitagliptin for 16 consecutive weeks...

Certain dietary components when combined with alcohol exacerbate alcohol-induced liver injury (ALI). Here, we tested whether fructose, a major ingredient of the western diet, enhances the severity of ALI. We fed mice ethanol for 8 weeks in the following Lieber-DeCarli diets: (a) Regular (contains olive oil); (b) corn oil (contains corn oil); (c) fructose (contains fructose and olive oil) and (d) corn+fructose (contains fructose and corn oil). We compared indices of metabolic function and liver pathology among the different groups...

Our recent studies have indicated that nucleolin, as a multifunctional RNA-binding protein, exerts protective effects in the myocardial cells and endothelial cells under the condition of oxidative stress. However, the function of nucleolin and its potential mechanism in macrophage-derived foam cell formation remain largely unexplored. ApoE-/- mice were fed with a high-fat diet (HFD) for 10-24 weeks. Protein expression was measured by western blotting or immunofluorescence, and gene expression at the mRNA level was detected by qRT-PCR...

Microcystin-LR (MCLR), one of the most popular microcystins (MCs) found in many field water bodies around the world, poses great health risks to animals and humans. In the present study, healthy common carp (initial weight 24.8 ± 2.3 g) were randomly assigned to five groups. Group I was fed on normal diet as control. Group II was maintained on normal diet and received MCLR intraperitoneal injection (150 μg kg(-1) BW). Common carp in groups III, IV, and V were daily pretreated with L-carnitine (LC) at doses of 0...

PURPOSE: Chronic exposure to stress may represent a risk factor for developing metabolic and eating disorders, mostly driven by the overconsumption of easily accessible energy-dense palatable food, although the mechanisms involved remain still unclear. In this study, we used an ethologically oriented murine model of chronic stress caused by chronic psychosocial defeat (CPD) to investigate the effects of unrestricted access to a palatable high fat diet (HFD) on food intake, body weight, energy homeostasis, and expression of different brain neuropeptides...

The with-no-lysine kinase (WNK) 4 gene is a causative gene in pseudohypoaldosteronism type II. Although WNKs are widely expressed in the body, neither their metabolic functions nor their extrarenal role is clear. In this study, we found that WNK4 was expressed in mouse adipose tissue and 3T3-L1 adipocytes. In mouse primary preadipocytes and in 3T3-L1 adipocytes, WNK4 was markedly induced in the early phase of adipocyte differentiation. WNK4 expression preceded the expression of key transcriptional factors PPARγ and C/EBPα...

BACKGROUND AND PURPOSE: Non-alcoholic steatohepatitis (NASH) is characterized by excessive intracellular lipid accumulation, inflammation and hepatic insulin resistance. Considering the rising prevalence of NASH worldwide, it is urgent to find novel interventional approaches. The pro-inflammatory cytokine IL-1β, generated and released from the Kupffer cells, is considered to be an initiating event in NASH. AS-1, a synthetic low-molecule mimetic to myeloid differentiation primary response gene 88 (MyD88), has been reported to disrupt the IL-1R-MyD88 interaction...

Depression is a complex disorder influenced by a variety of biological and environmental factors. Due to significant heterogeneity, there are remarkable differences in how patients respond to treatment. A primary objective of psychiatric research is to identify biological markers that could be used to better predict and enhance responses to antidepressant treatments. Diet impacts various aspects of health, including depression. The fatty acid composition of the Western diet, which has a high ratio of n-6:n-3 polyunsaturated fatty acids, is associated with increased incidence of depression...
