The interferon (IFN)-γ-activated inhibitor of translation (GAIT) system directs transcript-selective translational control of functionally related genes. In myeloid cells, IFN-γ induces formation of a multiprotein GAIT complex that binds structural GAIT elements in the 3'-untranslated regions (UTRs) of multiple inflammation-related mRNAs, including ceruloplasmin and VEGF-A, and represses their translation. The human GAIT complex is a heterotetramer containing glutamyl-prolyl tRNA synthetase (EPRS), NS1-associated protein 1 (NSAP1), ribosomal protein L13a (L13a), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH)...

The present study was conducted to characterize the major proteome of ovarian follicular fluid from locally-adapted, "Canindé" goats in the northeast of Brazil. Eight estrous cycling goats received a hormonal treatment consisting of medroxyprogesterone acetate, D-cloprostenol and FSH. Fluid was collected by laparoscopy from small (<3mm), medium (3-4mm) and large (>4mm) follicles and then, proteins were analyzed by 2-D SDS-PAGE and tandem mass spectrometry. Thirty-six proteins were identified in the goat follicular fluid, including albumin, immunoglobulins, ceruloplasmin, complement factor B, alpha-1B-glycoprotein precursor, serotransferrin, complement C3 and serpins, among others...

Human Ceruloplasmin belongs to the family of multi-copper oxidases and it is involved in different physiological processes, copper ion transport, iron metabolism, iron homeostasis, and biogenic amine metabolism. MD-simulation studies have indicated the higher hydrophilic susceptibility of the trinuclear copper cluster in native CP compared to its oxygen bound form. The copper (T2/T3) atom Cu3047 of the cluster, which is close to T1 copper center Cu3052 (~13 Å) has a higher affinity for water molecules compared to other copper centers...

In heartworm disease, several biomarkers of cardiopulmonary injury and inflammatory activity have been studied during the recent years. D-dimer is a fibrin degradation product present after a clot is degraded, which has been reported to provide support for the diagnosis of pulmonary thromboembolism in heartworm disease. Furthermore, concentrations increment with increased disease severity and during the adulticide treatment. This increase in concentration has proved to be valuable. Cardiac biomarkers troponin I, myoglobin and NT-proBNP demonstrated presence of myocardial injury and heart failure, especially in chronic infections, which in some cases, slightly improve after the adulticide treatment...

Changes in the stable isotope composition of copper in blood serum as a result of biological processes in the liver were quantified as coupled equilibrium fractionation processes. The model used calculated reduced partition function ratios corresponding to interactions involving individual proteins using Density Functional Theory. This quantified the effect that each process had on the redistribution of copper isotopes in the liver. It was not possible to calculate the reduced partition function of CTR1 as a high resolution crystal structure of its copper binding domains are unavailable at the time of writing, and an optimization process was used to estimate the reduced partition function of CTR1 and constrain the possible isotopic fractionation associated with interactions involving CTR1 independent of direct DFT calculations and assumptions of its structure...

Angiogenesis is a process of synthesis of new blood vessels from pre-existing vasculature. Copper (Cu) as a micronutrient is important to many proteins for their physiological roles. Cu is transported by ceruloplasmin from liver to other parts of the body. Copper transporter 1 (CTR1) is a transmembrane protein which participitate in Cu transport across the cell. It is also known to be involved in angiogenesis. In this study, we have designed three peptides from copper binding regions of CTR1 which are rich in histidine and methionine...

Cancer cells actively release extracellular vesicles, including exosomes, into the surrounding microenvironment. Exosomes play pleiotropic roles in cancer progression and metastasis, including invasion, angiogenesis, and immune modulation. However, the proteome profile of exosomes isolated from cells with different metastatic potential and the role of these exosomes in driving metastasis remains unclear. Here, we conducted a comparative proteomic analysis of exosomes isolated from several genetically related mouse breast tumour lines with different metastatic propensity...

Dengue fever (DF) is a major global health burden with a pathophysiology that is still incompletely understood. Biomarkers that predict and explain susceptibility to DF and its progression to its more severe hemorrhagic form are much needed. DF is endemic in tropical and subtropical regions of the world, with a rapidly increasing incidence of disease severity. We conducted a clinical biomarker discovery study using both a case-control and longitudinal study design. Plasma proteome alterations in patients with DF (n = 12) and dengue hemorrhagic fever (DHF, n = 24) were analyzed in comparison to healthy controls (HCs, n = 16), using the isobaric tags for relative and absolute quantification (iTRAQ)-based quantitative proteomics methodology (false discovery rate of 1%, ≥2 peptides)...

Type 2 diabetes mellitus (T2DM) is associated with oxidative stress and perturbed iron metabolism. Serotransferrin (Trf) and ceruloplasmin (Cp) are two key proteins involved in iron metabolism and anti-oxidant defense. Non-enzymatic glycation and oxidative modification of plasma proteins are known to occur under hyperglycemia and oxidative stress. In this study, shotgun proteomics and (2)H2O-based metabolic labeling were used to characterize post-translational modifications and assess the kinetics of Trf and Cp in T2DM patients and matched controls in vivo...

RNA-protein interactions with physiological outcomes usually rely on conserved sequences within the RNA element. By contrast, activity of the diverse g amma-interferon- a ctivated i nhibitor of t ranslation (GAIT)-elements relies on the conserved RNA folding motifs rather than the conserved sequence motifs. These elements drive the translational silencing of a group of chemokine (CC/CXC) and chemokine receptor (CCR) mRNAs, thereby helping to resolve physiological inflammation. Despite sequence dissimilarity, these RNA elements adopt common secondary structures (as revealed by 2D- 1 H NMR spectroscopy), providing a basis for their interaction with the RNA-binding GAIT complex...

PURPOSE: Pleural effusion, an accumulation of fluid in the pleural space, usually occurs in patients when the rate of fluid formation exceeds the rate of fluid removal. The differential diagnosis of tuberculous pleurisy and malignant pleural effusion is a difficult task in high tuberculous prevalence areas. The aim of the present study was to identify novel biomarkers for the diagnosis of pleural fluid using proteomics technology. MATERIALS AND METHODS: We used samples from five patients with transudative pleural effusions for internal standard, five patients with tuberculous pleurisy, and the same numbers of patients having malignant effusions were enrolled in the study...

Both waist circumference (WC) and waist-to-hip ratio (WHR) have been proposed as predictors of metabolic syndrome (MetS) in adolescents, but no consensus has been reached to date. This study hypothesizes that WC provides a greater predictive value for MetS in Spanish adolescents than WHR. A cross-sectional study was performed on 1001 adolescents (13.2 ± 1.2 years) randomly recruited from schools in southeast Spain. Anthropometric measures were correlated with the components of MetS (triglycerides, glucose, blood pressure, and high-density lipoprotein cholesterol) as well as inflammation markers (interleukin-6 and tumor necrosis factor-alpha , C-reactive protein, and ceruloplasmin)...

BACKGROUND: Systemic Lupus Erythematosus (SLE) is a multisystem autoimmune disease that disproportionately effects women and children of minorities. Renal involvement (lupus nephritis, or LN) occurs in up to 80% of children with SLE and is a major determinant of poor prognosis. We have developed a non-invasive pediatric Renal Activity Index for Lupus (p-RAIL) that consists of laboratory measures that reflect histologic LN activity. These markers are neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), monocyte chemotactic protein (MCP-1), adiponectin (APN), ceruloplasmin (CP) and hemopexin (HPX)...

BACKGROUND: Wilson's disease is a genetic disorder in which copper accumulates in the liver, brain, and other tissues. Therapies are limited by efficacy, safety concerns, and multiple daily dosing. Bis-choline tetrathiomolybdate (WTX101) is an oral first-in-class copper-protein-binding molecule that targets hepatic intracellular copper and reduces plasma non-ceruloplasmin-bound copper (NCC) by forming tripartite complexes with albumin and increasing biliary copper excretion. We aimed to assess the efficacy and safety of WTX101 in the initial or early treatment of patients with Wilson's disease...

The year 2016 marked the 50th anniversary of the discovery by S. Osaki who first showed that ceruloplasmin (CP, ferro:O2-oxidoreductase or ferroxidase) is capable of oxidizing Fe(II) to Fe(III) and favors the incorporation of the latter into transferrin (TF). However, much debate remains in the literature concerning the existence of a complex between the enzyme oxidizing iron and the protein facilitating its transport in plasma. We studied CP in exocrine fluids and demonstrated its high-affinity interaction with transferrin found in breast milk and in lacrimal fluid, i...
