The scavenger receptor and multiligand transporter CD36 functions to promote cellular free fatty acid uptake and regulates aspects of both hepatic and intestinal cholesterol metabolism. However, the role of CD36 in regulating canalicular and biliary cholesterol transport and secretion is unknown. Here we show that germline Cd36 knockout mice are protected against lithogenic diet (LD) induced gallstones compared to congenic (C57BL6/J) controls. Cd36 knockout mice crossed into congenic L-Fabp knockout mice (DKO mice) demonstrated protection against LD induced gallstones, reversing the susceptibility phenotype observed in L-Fabp knockout mice...

Acetaminophen (paracetamol) (PAR) is one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) with analgesic and antipyretic properties consumed worldwide and often detected in the aquatic environment. Due to the fact that PAR induces oxidative stress in mammals, the aim of this study was to evaluate if similar effects were observed in oysters Crassostrea gigas, given their economic and ecological importance and worldwide distribution. Oysters were exposed for 1, 4 and 7 days to two different sublethal PAR concentrations (0, 1 and 100μgL(-1))...

Human FABP5 and FABP7 are intracellular endocannabinoid transporters. SBFI-26 is an -truxillic acid 1-naphthyl monoester that competitively inhibits the activities of FABP5 and FABP7 and produces antinociceptive and anti-inflammatory effects in mice. The synthesis of SBFI-26 yields several stereoisomers, and it is not known how the inhibitor binds the transporters. Here we report co-crystal structures of SBFI-26 in complex with human FABP5 and FABP7 at a resolution of 2.2 Å and 1.9 Å, respectively. We found that only (S)-SBFI-26 was present in the crystal structures...

BACKGROUND: Intestinal fatty acid-binding protein (I-FABP) has been shown to be of high diagnostic value in patients with acute mesenteric ischemia. Whether these results can be reproduced in critically ill patients on the ICU was to be investigated. MATERIALS AND METHODS: I-FABP was measured in serum and urine of 43 critically ill patients in ICU when mesenteric ischemia was suspected. Bowel ischemia was confirmed in 21 patients (group 1). 22 patients who survived at least seven days without confirmation of ischemia were assigned to group 2...

Human embryonic stem cells (hESCs), with the potential for differentiation, have been used to evaluate the embryotoxicity of various compounds. The effects of pharmacological compounds (cytosine arabinoside, 5-fluorouracil, hydroxyurea, indomethacin, and dexamethasone) on neurogenesis of hESCs over 28 days were examined based on cytotoxicity (half-maximal inhibitory concentration of viability, IC50) and expression of neural markers. Cytosine arabinoside, 5-fluorouracil, and hydroxyurea showed strong cytotoxicity (IC50 < 10 μM), whereas indomethacin and dexamethasone had weaker cytotoxic effects...

RATIONALE: Up to one-third of the patients hospitalized with pneumococcal pneumonia experience major adverse cardiac events (MACE) during or after pneumonia. In mice, Streptococcus pneumoniae can invade the myocardium, induce cardiomyocyte death, and disrupt cardiac function following bacteremia, but it is unknown whether the same occurs in humans with severe pneumonia. OBJECTIVE: We sought to determine whether S. pneumoniae can 1) translocate the heart, 2) induce cardiomyocyte death, 3) cause MACE, and 4) induce cardiac scar formation post-antibiotic treatment during severe pneumonia using a non-human primates (NHP) model...

AIMS/HYPOTHESIS: In type 1 diabetes, cardiovascular disease (CVD) and diabetic nephropathy progress in parallel, thereby potentiating the risk of premature death during their development. Since urinary liver-type fatty acid binding protein (L-FABP) predicts the progression of diabetic nephropathy, the aim of this study was to investigate whether urinary L-FABP also predicts cardiovascular outcomes and mortality. METHODS: We tested our hypothesis in a Finnish cohort of 2329 individuals with type 1 diabetes and a median follow-up of 14...

BACKGROUND: It has been reported that lipid-rich enteral nutrition (EN) could ameliorate inflammation in various diseases. In this study, we investigated whether lipid-rich EN could control intestinal inflammation, improve intestinal motility and mucosal barrier injury after intestinal ischemia/reperfusion (I/R) injury. METHODS: Male adult rats received saline, conventional EN, or lipid-rich EN via gavage before and after intestinal I/R injury. The superior mesenteric artery was occluded for 60 min...

There is little information available on the effect of Gestational diabetes mellitus (GDM) treatment (diet or insulin) on placental lipid carriers, which may influence fetal fat accretion. Insulin may activate placental insulin receptors protein kinase (AKT) and extracellular signal regulated kinase ERK mediators, which might affect lipid metabolism. Placenta was collected from 25 control women, 23 GDM-Diet and 20 GDM-Insulin. Western blotting of insulin signaling mediators and lipid carriers was performed...

Background: We hypothesized that low-grade inflammation was driven by microbial translocation and associated with an increased risk of healthcare-associated infections (HAIs). Methods: We included 121 patients aged 75 years or over in this prospective cohort study. High-sensitivity C-reactive protein (hs-CRP), I-FABP, and sCD14 -- as markers for low-grade inflammation, intestinal epithelial barrier integrity, and monocyte activation, respectively -- were measured at admission...

Oocytes that undergo in vitro maturation (IVM) are metabolically abnormal and accumulate excess lipid content. However, the mechanism of lipid accumulation and the role of cumulus cells in this process are unclear. Recently, it was shown that fatty acid binding proteins (FABPs) performed intra- and extracellular fatty acid transport. We postulated that FABP3 might be responsible for fatty acid transport from cumulus cells to the oocytes via transzonal projections (TZPs) during IVM. Transcript and protein levels of FABP3 were analyzed in both in vivo- and in vitro-matured cumulus-oocyte-complexes and were increased in IVM samples...

INTRODUCTION: Acute hepatitis is acute inflammation of liver elicited by a large number of causes. It sometimes spontaneously recovers, sometimes may progress to chronic hepatitis. Liver- Fatty Acid Binding Protein (L-FABP) is a small protein that is abundant in hepatocytes, and which binds most of the long-chain fatty acids present in the cytosol. AIM: The present study was aimed to investigate the levels of serum and urine L-FABP in acute hepatitis and diagnostic value of serum and urine L-FABP levels in patients with acute hepatitis...

BACKGROUND: Although cardiac troponin is the cornerstone in diagnosis of acute myocardial infarction (AMI), the accuracy is still suboptimal in the early hours after chest pain onset. Due to its small size, heart-type fatty acid-binding protein (H-FABP) has been reported accurate in diagnosis of AMI, however, this remains undetermined. The aim is to investigate the diagnostic performance of H-FABP alone and in conjunction with high-sensitivity troponin (hs-Tn) within six hours of symptom onset...

Cellular uptake of long chain fatty acids in human placental trophoblasts is thought to be mediated by several membrane- and cytoplasmic fatty acid-binding proteins (FABP). FABP3 was shown to be involved in long chain polyunsaturated fatty acids (LCPUFA) uptake in human trophoblastic choriocarcinoma cells, BeWo as the uptake of arachidonic acid,20:4n-6 (ARA) was decreased in FABP3-knockdown BeWo cells. However, the regulation of expression of FABP3 in these cells is not yet well known. The aim of the present study was to examine the FABP3 expression by LCPUFAs, insulin and LXR agonists in BeWo cells...
