Association of a peripheral blood metabolic profile with coronary artery disease and risk of subsequent cardiovascular events.
(Circ Cardiovasc Genet, 2010-04)BACKGROUND: Molecular tools may provide insight into cardiovascular risk. We assessed whether metabolites discriminate coronary artery disease (CAD) and predict risk of cardiovascular events. METHODS AND RESULTS: We performed ... -
Cell surface glycoproteomic analysis of prostate cancer-derived PC-3 cells.
(Bioorganic & medicinal chemistry letters, 2011-09)Most clinically approved biomarkers of cancer are glycoproteins, and those residing on the cell surface are of particular interest in biotherapeutics. We report a method for selective labeling, affinity enrichment, ... -
Complement-Mediated Regulation of Apolipoprotein E in Cultured Human RPE Cells.
(Investigative ophthalmology & visual science, 2017-06)Complement activation is implicated in the pathogenesis of age-related macular degeneration (AMD). Apolipoprotein E (ApoE) and complement activation products such as membrane attack complex (MAC) are present in ... -
Coordination of platinum therapeutic agents to met-rich motifs of human copper transport protein1.
(Metallomics, 2010-01)Platinum therapeutic agents are widely used in the treatment of several forms of cancer. Various mechanisms for the transport of the drugs have been proposed including passive diffusion across the cellular membrane and active ... -
Design, Fabrication, and Characterization of Carbon Nanotube Field Emission Devices for Advanced Applications
(2016)Carbon nanotubes (CNTs) have recently emerged as promising candidates for electron field emission (FE) cathodes in integrated FE devices. These nanostructured carbon materials possess exceptional properties and their synthesis ... -
Development and Applications of Chemical Labeling Protocols for Protein-Ligand Binding Analysis Using Bottom-Up Proteomics
(2011)Proteins fold into well-defined three-dimensional structures to carry out their biological functions which involve non-covalent interactions with other cellular molecules. Knowledge about the thermodynamic properties of ... -
Elucidating the Molecular Composition of Cartilage by Proteomics.
(J Proteome Res, 2016-02-05)Articular cartilage consists of chondrocytes and two major components, a collagen-rich framework and highly abundant proteoglycans. Most prior studies defining the zonal distribution of cartilage have extracted proteins ... -
Global Analysis of Protein Folding Thermodynamics for Disease State Characterization and Biomarker Discovery
(2015)Protein biomarkers can facilitate the diagnosis of many diseases such as cancer and they can be important for the development of effective therapeutic interventions. Current large-scale biomarker discovery and disease state ... -
Immunomodulatory lipid mediator profiling of cerebrospinal fluid following surgery in older adults.
(Scientific reports, 2021-02-04)Arachidonic acid (AA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) derived lipids play key roles in initiating and resolving inflammation. Neuro-inflammation is thought to play a causal role in perioperative ... -
Instrument Design and Study of Operational Characteristics of a Cycloidal Coded Aperture Miniature Mass Spectrometer for Environmental Sensing
(2020)Effluence of organic compounds like benzene, toluene, ethylbenzene and xylenes (“BTEX”), and methane from an industrial setting can have a negative impact on human health and the environment. Miniature sector mass spectrometers ... -
Mass Spectrometry-Based Strategies for Multiplexed Analyses of Protein-Ligand Binding Interactions
(2011)The detection and quantitation of protein-ligand binding interactions is important not only for understanding biological functions but also for the characterization of novel protein ligands. Because protein ligands can ... -
Nasopharyngeal Protein Biomarkers of Acute Respiratory Virus Infection.
(EBioMedicine, 2017-03)Infection of respiratory mucosa with viral pathogens triggers complex immunologic events in the affected host. We sought to characterize this response through proteomic analysis of nasopharyngeal lavage in human subjects ... -
Parental dietary seleno-L-methionine exposure and resultant offspring developmental toxicity.
(Aquatic toxicology (Amsterdam, Netherlands), 2016-01)Selenium (Se) leaches into water from agricultural soils and from storage sites for coal fly ash. Se toxicity causes population and community level effects in fishes and birds. We used the laboratory aquarium model fish, ... -
Proteome-wide muscle protein fractional synthesis rates predict muscle mass gain in response to a selective androgen receptor modulator in rats.
(Am J Physiol Endocrinol Metab, 2016-03-15)Biomarkers of muscle protein synthesis rate could provide early data demonstrating anabolic efficacy for treating muscle-wasting conditions. Androgenic therapies have been shown to increase muscle mass primarily by increasing ... -
Small ubiquitin-like modifier 3-modified proteome regulated by brain ischemia in novel small ubiquitin-like modifier transgenic mice: putative protective proteins/pathways.
(Stroke, 2014-04)<h4>Background and purpose</h4>Small ubiquitin-like modifier (SUMO) conjugation is a post-translational modification associated with many human diseases. Characterization of the SUMO-modified proteome is pivotal to define ... -
Structural basis of O-GlcNAc recognition by mammalian 14-3-3 proteins.
(Proceedings of the National Academy of Sciences of the United States of America, 2018-06)O-GlcNAc is an intracellular posttranslational modification that governs myriad cell biological processes and is dysregulated in human diseases. Despite this broad pathophysiological significance, the biochemical effects ... -
Succinylated octopamine ascarosides and a new pathway of biogenic amine metabolism in Caenorhabditis elegans.
(J Biol Chem, 2013-06-28)The ascarosides, small-molecule signals derived from combinatorial assembly of primary metabolism-derived building blocks, play a central role in Caenorhabditis elegans biology and regulate many aspects of development and ... -
Tenascin-C is an innate broad-spectrum, HIV-1-neutralizing protein in breast milk.
(Proceedings of the National Academy of Sciences of the United States of America, 2013-11)Achieving an AIDS-free generation will require elimination of postnatal transmission of HIV-1 while maintaining the nutritional and immunologic benefits of breastfeeding for infants in developing regions. Maternal/infant ... -
Total body skeletal muscle mass: estimation by creatine (methyl-d3) dilution in humans.
(J Appl Physiol (1985), 2014-06-15)Current methods for clinical estimation of total body skeletal muscle mass have significant limitations. We tested the hypothesis that creatine (methyl-d3) dilution (D3-creatine) measured by enrichment of urine D3-creatinine ...
