Brown adipose tissue (BAT) and beige adipose tissue combust fuels for heat production in adult humans, and so constitute an appealing target for the treatment of metabolic disorders such as obesity, diabetes and hyperlipidemia. Cold exposure can enhance energy expenditure by activating BAT, and it has been shown to improve nutrient metabolism. These therapies, however, are time consuming and uncomfortable, demonstrating the need for pharmacological interventions. Recently, lipids have been identified that are released from tissues and act locally or systemically to promote insulin sensitivity and glucose tolerance; as a class, these lipids are referred to as 'lipokines'...

Chronic inflammatory diseases of the airways are associated with gastro-oesophageal reflux (GOR) and aspiration events. The observation of lipid-laden macrophages (LLMs) within the airway may indicate aspiration secondary to GOR. The proposed mechanism, that lipid droplets from undigested or partially digested food are aspirated leading to accumulation in scavenging macrophages, led us to hypothesise that an activated population of LLMs could interact with other immune cells to induce bronchial inflammation...

Sex steroid hormones, such as estrogen and testosterone, are believed to play important roles in lipid metabolism. To elucidate the effects of estrogen depletion on lipid metabolism in male and female mice, we used aromatase-knockout (ArKO) mice, in which Cyp19 gene disruption prevented estrogen synthesis in vivo. These mice were divided into the following 4 groups: male and female ArKO mice and male and female wild-type (WT) mice. These mice were fed a normal-fat diet (13.6% fat) ad libitum. At 159 days after birth, the mice were tested for liver and plasma lipid content and hepatic hormone receptor- and lipid/lipoprotein metabolism-related gene expression...

Some factors related to diet, such as trans fatty acids (TFA), are known to be involved in the progression of atherosclerosis in humans. Thus, the aim of our study was (i) to evaluate the effects of three dietary free fatty acids (FFA) (elaidic (EA), oleic (OA) and palmitic acid (PA)) on U937 human monocytes, and (ii) to study the eventual benefits of bezafibrate (BZF), a pan-agonist for PPAR isoforms (α, γ and δ) in U937 cells treated with FFA. Morphologic and functional changes were investigated by microscopic and flow cytometric methods...

SUMMARYCluster of differentiation 36 (CD36) is a transmembrane protein that recognizes multiple diverse ligands. It is believed that (i) oxidized glycerophosphocholine species having a terminal γ-hydroxyl(or oxo)-α,β-unsaturated carbonyl on the sn-2 acyl group (oxGPCCD36), which can occur on the surface of lipoprotein particles, serve as high-affinity ligands for CD36, and (ii) the amino acid 150-168 of CD36 (CD36150-168) is responsible for recognizing oxGPCCD36. However, it remains uncertain whether CD36150-168 directly interacts with oxGPCCD36 alone...

The plasma transmembrane (TM) glycoprotein CD36 is critically involved in many essential signaling processes, especially the binding /uptake of long-chain fatty acids and oxidized low-density lipoproteins. The association of CD36 potentially activates cytosolic protein tyrosine kinases that are thought to associate with the C-terminal cytoplasmic tail of CD36. To understand the mechanisms by which CD36 mediates ligand binding and signal transduction, we have characterized the homo- oligomeric interaction of CD36 TM domains in membrane environments and with molecular dynamics (MD) simulations...

Atherothrombosis is a process mediated by dysregulated platelet activation that can cause life-threatening complications and is the leading cause of death by cardiovascular disease. Platelet reactivity in hyperlipidemic conditions is enhanced when platelet scavenger receptor CD36 recognizes oxidized lipids in LDL particles, a process which induces an overt prothrombotic phenotype. The mechanisms by which CD36 promotes platelet activation and thrombosis remain incompletely defined. In this study, we identify a mechanism for CD36 to promote thrombosis by increasing activation of MAP kinase ERK5, a protein kinase known to be exquisitely sensitive to redox stress, through a signaling pathway requiring Src kinases, NADPH oxidase, superoxide radical anion and hydrogen peroxide...

Study Objectives: Increased visceral white adipose tissue (vWAT) mass results in infiltration of inflammatory macrophages that drive inflammation and insulin resistance. Patients with obstructive sleep apnea (OSA) suffer from increased prevalence of obesity, insulin resistance and metabolic syndrome. Murine models of intermittent hypoxia (IH) mimicking moderate-severe OSA manifest insulin resistance following short-term IH. We examined in mice the effect of long-term IH on the inflammatory cellular changes within vWAT, and the potential effect of normoxic recovery (IH-R)...

Background: Obesity is associated with an increase in adipogenesis and is becoming a serious health problem in modern society. Objective: The effects of various Solidago virgaurea var. gigantean (SV) ethanolic aqueous extracts on anti-adipogenesis in 3T3-L1 cells were investigated. In addition, the effect of SV 10% ethanolic extract (SV10E) on preventing obesity was studied in high-fat diet-induced obese mice (C57BL/6 N). Design: The effect of SV10E on preventing obesity was studied in mice (n = 6): normal-fat diet, high-fat diet (HFD), HFD supplemented with 1% (10 g/kg) Garcinia cambogia extract of 60% (-)-hydroxycitric acid (positive control), HFD supplemented with 0...

Hexarelin, a synthetic growth hormone-releasing peptide, has been proven to possess cardioprotective actions through its binding to the growth hormone secretagogue receptor (GHSR) 1a and the non-GHSR receptor CD36. However, its effect on myocardial ischemia/reperfusion (I/R) injury has not been fully clarified in vivo. We aimed to determine whether hexarelin treatment could protect cardiomyocytes from I/R injury and to examine the underlying mechanisms. In vivo hearts of male SD rats underwent 30 minutes of ischemia by left coronary artery ligation followed by reperfusion...

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...

Dietary fat overconsumption leads to myocardial lipid accumulation through mechanisms that are incompletely resolved. Previously, we identified increased translocation of the fatty acid transporter CD36 from its endosomal storage compartment to the sarcolemma as primary mechanism of excessive myocellular lipid import. Here, we show that increased CD36 translocation is caused by alkalinization of endosomes due to inhibition of proton pumping activity of vacuolar-type H(+)-ATPase (v-ATPase). Endosomal alkalinization was observed in hearts from rats fed a lard-based high fat-diet and in rodent and human cardiomyocytes upon palmitate overexposure, and appeared as early lipid-induced event preceding the onset of insulin resistance...

Lingual fatty acid receptors (i.e. CD36) mediate the orosensory perception of fat/fatty acids and may contribute to the susceptibility to develop obesity. The current study tested the hypothesis that fat/fatty acid preference in obesity-prone (OP, Osborne-Mendel) and obesity-resistant (OR, S5B/Pl) rats is mediated by nutritional status and lingual CD36. To determine if nutritional status affected linoleic acid (LA) preference in OP and OR rats, rats were either fasted overnight or fed a high fat diet (60% kcal from fat)...

OBJECTIVES: Compared with subcutaneous adipose tissue (SCAT), infrapatellar fat pad (IFP), the main knee intra-articular adipose tissue (IAAT), has an inflammatory phenotype in patients with osteoarthritis (OA). We phenotyped suprapatellar fat pad (SPFP) and hip acetabular fat pad (AFP), two other IAATs, to determinate the unique signature of IAATs compared with SCAT. METHODS: IFP, SPFP, AFP and autologous SCAT were obtained from patients with OA during total knee (n=38) or hip replacement (n=5)...

OBJECTIVE: Fetal macrosomia is associated with cardiac hypertrophy and increased cardiovascular risk. Cardiac biomarkers may play diagnostic/prognostic role in cardiovascular disease. We tested whether cardiac biomarkers are differentially expressed in cord blood samples of full-term singleton large-for-gestational-age (LGA), as compared to appropriate-for-gestational-age (AGA) pregnancies. METHODS: Cardiotrophin-1 (CT-1), Titin, pentraxin (PTX-3) and soluble CD36 (sCD36) concentrations were determined in 80 cord blood samples from a) LGA pregnancies due to maternal diabetes (n = 8), overweight/obese (n = 11), excessive weight gain (n = 7), without specific pathology (n = 14), b) AGA normal pregnancies (controls, n = 40)...

Body mass and fat intake are multifactorial traits that have genetic and environmental components. The gene with the greatest effect on body mass is FTO (fat mass and obesity-associated), but several studies have shown that the effect of FTO (and of other genes) on body mass can be modified by the intake of nutrients. The so-called gene-environment interactions may also be important for the effectiveness of weight-loss strategies. Food choices, and thus fat intake, depend to some extent on individual preferences...

HDAC3 has been shown to regulate inflammation. However, the role of HDAC3 in primary microglia is largely unknown. RGFP966 is a newly discovered selective HDAC3 inhibitor. In this study, we used protein mass spectrometry to analyze protein alterations in LPS-treated primary microglia with the application of RGFP966. Generally, about 2000 proteins were studied. 168 of 444 (37.8%) LPS-induced proteins were significantly reduced with the treatment of RGFP966, which mainly concentrated on Toll-like receptor signaling pathway...

As well as systemic vascular endothelial cells, the liver has specialised sinusoidal endothelial cells (LSEC). LSEC dysfunction has been documented in many diseased states yet their phenotype in normal human liver has not been comprehensively assessed. Our aim was to improve characterisation of subsets of endothelial cells and associated pericytes in the human liver. Immunofluorescence microscopy was performed on normal human liver tissue samples to assess endothelial and structural proteins in a minimum of three donors...

Nonalcoholic fatty liver disease (NAFLD) is characterized by simple hepatic steatosis (SS), nonalcoholic steatohepatitis (NASH), hepatic fibrosis, and cirrhosis. Dysregulated fatty acid metabolism in the liver plays a critical role in the pathogenesis of NAFLD. Cytochrome P450 omega-hydroxylase 4A14 (CYP4A14) is a homolog of human CYP4A hydroxylase that catalyzes omega-hydroxylation of medium-chain fatty acids and arachidonic acid in mice. The goal of this study was to determine the role of CYP4A14 in the development and the progression of NAFLD...
