Preclinical changes that precede the onset of symptoms and eventual diagnosis of Alzheimer's disease (AD) are a target for potential preventive interventions. A large body of evidence suggests that inflammation is closely associated with AD pathogenesis and may be a promising target pathway for such interventions. However, little is known about the association between systemic inflammation and preclinical AD pathophysiology. We first examined whether the acute-phase protein, alpha-2 macroglobulin (A2M), a major component of the innate immune system, was associated with cerebrospinal fluid (CSF) markers of neuronal injury in preclinical AD and risk of incident AD in the predictors of cognitive decline among normal individuals (BIOCARD) cohort...

OBJECTIVES: This study was performed to evaluate the potential efficacy of natural eggshell membrane (NEM) in collagen-induced arthritic rats, a well-established rodent model of inflammation and rheumatoid arthritis. METHODS: Rats with developing type II collagen-induced arthritis (CIA) were treated once daily by oral gavage on study days -14 to 17 with vehicle or NEM (52 mg/kg body weight). Rats were euthanized on study day 17. Efficacy was assessed by daily ankle caliper measurements, ankle diameter expressed as area under the curve (AUCd0-17), and histopathologic evaluation of ankles and knees...

AIMS: Proteomic analysis of serum biomarkers to determine liver toxicity after exposure to cosmic radiation has not been performed previously. This study was to identify serum biomarkers associated with hepatotoxicity following exposure to iron ion radiation. MAIN METHODS: Male mice were whole-body irradiated with a 2grayunit (Gy) iron ion beam, and after 3months, serum and liver samples were collected. Two-dimensional electrophoresis was used to separate the identified serum proteins, and matrix-assisted laser desorption/ionization tandem mass spectrometry (MALDI-TOF-TOF) was performed to identify differentially abundant proteins...

Hypocalcemia is an important metabolic disease of dairy cows during the transition period, although the effect of hypocalcemia on biological function in dairy cows remains unknown. In this study, proteomic, mass spectrum, bioinformatics and western blotting were employed to identify differentially expressed proteins related to serum Ca concentration. Serum samples from dairy cows were collected at three time points: 3rd days before calving (day -3), the day of calving (day 0), and 3rd days after calving (day +3)...

L Renee Ruhaak
In recent years, high-throughput glycomics approaches have been developed and applied to either complete biofluids, cell lysates or tissues, or proteins isolated thereof. However, during such analyses the N-glycan are released from the protein backbone and therefore site- and protein-specific information is lost. There exists a need for high-throughput methods that allow quantification of site- and protein-specific glycosylation patterns from complex biological mixtures. We here describe the use of a multiple reaction monitoring mass spectrometry based method for the generation of glycopeptide profiles of the nine high abundance glycoproteins IgG, IgA, IgM, haptoglobin, alpha-1-antitrypsin, alpha-2-macroglobulin, alpha-1-acid glycoprotein, transferrin, and complement C3...

RATIONALE: COPD exacerbations are associated with disease progression, higher healthcare cost, and increased mortality. Published predictors of future exacerbations include previous exacerbation, airflow obstruction, poor overall health, home oxygen use, and gastroesophageal reflux. The value of adding blood biomarkers to clinical variables to predict exacerbations remains unproven. METHODS: Subjects from SPIROMICS (n=1544) and COPDGene (n=602) cohorts had 90 plasma or serum candidate proteins measured on study entry using Myriad-RBM multiplex panels...

Fucosylation of N-glycoproteins has been implicated in various diseases, such as hepatocellular carcinoma (HCC). However, few studies have performed site-specific analysis of fucosylation in liver-secreted proteins. In this study, we characterized the fucosylation patterns of liver-secreted proteins in HCC plasma using a workflow to identify site-specific N-glycoproteins, where characteristic B- and/or Y-ion series with and without fucose in collision-induced dissociation were used in tandem mass spectrometry...

UNLABELLED: The early diagnosis and successful treatment of breast cancer (BC) is still a challenging task due to the diverse origin and functional heterogeneity of cancer cells. The heterogeneity of BC may likely to explained by molecular BC subtypes, comprises Luminal-A (LA), Luminal-B (LB), Triple-negative (TN) and HER2-positive (HP), which are governed by a variety of cancer associated pathways. To identify protein signatures in different BC subtypes, we performed isobaric tag for absolute and relative quantitation (iTRAQ) of enriched blood plasma samples of BC subtypes (N=32) and healthy subjects (N=8)...

Alpha-2 macroglobulin (α2M) is a ubiquitous protease inhibitor and considered to be an evolutionarily conserved constituent of innate host defence system. Here, an α2M gene (designated as Pfα2M) was obtained from the pearl oyster Pinctada fucata by RT-PCR, PCR walking and rapid amplification of cDNA ends (RACE). The Pfα2M cDNA consists of 6394 bp with an open reading frame (ORF) of 5745 bp encoding a protein of 1914 amino acids with a 19 residues signal peptide. Pfα2M sequence contains three putative functional domains, including a bait region, a thiol ester domain and a receptor-binding domain...

Fibrinogen is a plasma glycoprotein and one of the principle participants in blood coagulation. It interacts with many proteins during formation of a blood clot, including insulin-like growth factors (IGFs) and their binding proteins (IGFBP). Fibrinogen complexes were found as minor fractions in fibrinogen preparations independently of the coagulation process, and their presence influences the kinetics of polymerization. The idea of this work was to investigate whether fibrinogen in human plasma interacts with IGFBPs independently of the tissue injury or coagulation process...

Glycosaminoglycan (GAG) from cricket (Gryllus bimaculatus) was studied as a potential health supplement. Antiatherosclerotic and antilipidemic effects of the GAG of G. bimaculatus (GbG, 5 or 10 mg/kg) were investigated in 15-week old Wistar rats treated with GbG for over a month. GbG produced a meaningful anti-edema effect with inhibition of C-reactive protein (CRP). Also, the weights of abdominal and epididymidal fat were also reduced in conjunction with a mild increase in body weight. Furthermore, the sero-biochemical parameters showed an antihyperlipidemic effect with decreased levels of phospholipid, AST, ALT, total cholesterol and glucose in a dose-dependent manner...

Mya truncata, a soft shell clam, is presented as a new model to study biomineralization through a proteomics approach. In this study, the shell and mantle tissue were analysed in order to retrieve knowledge about the secretion of shell matrix proteins (SMPs). Out of 67 and 127 shell and mantle proteins respectively, 16 were found in both shell and mantle. Bioinformatic analysis of SMP sequences for domain prediction revealed the presence of several new domains such as fucolectin tachylectin-4 pentraxin-1 (FTP), scavenger receptor, alpha-2-macroglobulin (α2 M), lipocalin and myosin tail along with previously reported SMP domains such as chitinase, carbonic anhydrase, tyrosinase, sushi, and chitin binding...

The large-conductance, voltage-gated, calcium (Ca(2+))-activated potassium channel (BKCa) plays an important role in regulating Ca(2+)signaling and is implicated in the maintenance of uterine quiescence during pregnancy. We used immunopurification and mass spectrometry to identify proteins that interact with BKCain myometrium samples from term pregnant (≥37 wk gestation) women. From this screen, we identified alpha-2-macroglobulin (α2M). We then used immunoprecipitation followed by immunoblot and the proximity ligation assay to confirm the interaction between BKCaand both α2M and its receptor, low-density lipoprotein receptor-related protein 1 (LRP1), in cultured primary human myometrial smooth muscle cells (hMSMCs)...
