Identification of Potential Autoantigens in Anti-CCP-Positive and Anti-CCP-Negative Rheumatoid Arthritis Using Citrulline-Specific Protein Arrays
www.nature.com/scientificreports OPEN Identifcation of potential autoantigens in anti‑CCP‑positive and anti‑CCP‑negative rheumatoid arthritis using citrulline‑specifc protein arrays Thomas B. G. Poulsen 1,2, Dres Damgaard 3, Malene M. Jørgensen 4,5, Ladislav Senolt6, Jonathan M. Blackburn 7, Claus H. Nielsen 3,8 & Allan Stensballe 1,8* The presence or absence of autoantibodies against citrullinated proteins (ACPAs) distinguishes two main groups of rheumatoid arthritis (RA) patients with diferent etiologies, prognoses, disease severities, and, presumably, disease pathogenesis. The heterogeneous responses of RA patients to various biologics, even among ACPA‑positive patients, emphasize the need for further stratifcation of the patients. We used high‑density protein array technology for fngerprinting of ACPA reactivity. Identifcation of the proteome recognized by ACPAs may be a step to stratify RA patients according to immune reactivity. Pooled plasma samples from 10 anti‑CCP‑negative and 15 anti‑CCP‑positive RA patients were assessed for ACPA content using a modifed protein microarray containing 1631 diferent natively folded proteins citrullinated in situ by protein arginine deiminases (PADs) 2 and PAD4. IgG antibodies from anti‑CCP‑positive RA plasma showed high‑intensity binding to 87 proteins citrullinated by PAD2 and 99 proteins citrullinated by PAD4 without binding signifcantly to the corresponding native proteins. Curiously, the binding of IgG antibodies in anti‑CCP‑negative plasma was also enhanced by PAD2‑ and PAD4‑mediated citrullination of 29 and 26 proteins, respectively. For only four proteins, signifcantly more ACPA binding occurred after citrullination with PAD2 compared to citrullination with PAD4, while the opposite was true for one protein.

The Protein Arginine Deiminases
The Protein Arginine Deiminases: Inhibitors and Characteristics By Elizabeth Joanne Curiel Tejeda A thesis submitted in conformity with the requirements for the degree of Master of Science Pharmaceutical Sciences University of Toronto © Copyright by Elizabeth Joanne Curiel Tejeda (2015) Abstract The Protein Arginine Deiminases: Inhibitors and Characteristics MSc Pharmaceutical Sciences Convocation year of 2015 Elizabeth Joanne Curiel Tejeda Department of Pharmaceutical Sciences University of Toronto Protein arginine deiminases (PADs) are Ca2+ dependent enzymes involved in the post- translational modification of proteins through citrullination. Overexpression of PAD2 and PAD4 has been observed in a number of neurodegenerative diseases. In this thesis, two broad investigations were undertaken to look at the expression patterns of endogenous PADs and how they provide means to the development of disease modifying treatments. First, a BODIPY-based fluorescent probe was designed to assess the expression levels in vitro and in vivo of endogenous PAD. Secondly, medicinal chemistry approaches were adopted to design a library of novel non-covalent compounds to establish a structure activity relationship on PADs and identify a potential hit. Results indicated that a BODIPY-based biomarker was a feasible approach to monitor PAD enzymes in vivo. Through structure-activity relationship investigations, it was established that small heterocycles on an amino acid side chain were contributing to the inhibitory activities towards PADs. Declaration of Work: All synthetic experiments, synthesis of library of compounds, and confocal microscopy studies were performed by Elizabeth J. Curiel Tejeda. Biological assays and evaluations were performed by Ms. Ewa Wasilewski. ii Acknowledgements I would like thank Dr. Lakshmi Kotra for giving me the opportunity to work in his laboratory and expand my knowledge in the drug development research field.

A total of 2110 proteins were identified in “Huangjinya”, and 173 proteins showed differential accumulations between the chlorotic and normal green leaves. Of these, 19 proteins were correlated with RNA expression levels, based on integrated analyses of the transcriptome and proteome. Moreover, the results of our analysis of differentially expressed proteins suggested that primary carbon metabolism (i.e., carbohydrate synthesis and transport) was inhibited in chlorotic tea leaves. The differentially expressed genes and proteins combined with photosynthetic phenotypic data indicated that 4-coumarate-CoA ligase (4CL) showed a major effect on repressing flavonoid metabolism, and abnormal developmental chloroplast inhibited the accumulation of chlorophyll and flavonoids because few carbon skeletons were provided as a result of a weakened primary carbon metabolism.

Comparative Genomics of Bradyrhizobium Japonicum CPAC
Siqueira et al. BMC Genomics 2014, 15:420 http://www.biomedcentral.com/1471-2164/15/420 RESEARCH ARTICLE Open Access Comparative genomics of Bradyrhizobium japonicum CPAC 15 and Bradyrhizobium diazoefficiens CPAC 7: elite model strains for understanding symbiotic performance with soybean Arthur Fernandes Siqueira1,2†, Ernesto Ormeño-Orrillo3†,RangelCelsoSouza4,ElisetePainsRodrigues5, Luiz Gonzaga Paula Almeida4, Fernando Gomes Barcellos5, Jesiane Stefânia Silva Batista6, Andre Shigueyoshi Nakatani2, Esperanza Martínez-Romero3, Ana Tereza Ribeiro Vasconcelos4 and Mariangela Hungria1,2* Abstract Background: The soybean-Bradyrhizobium symbiosis can be highly efficient in fixing nitrogen, but few genomic sequences of elite inoculant strains are available. Here we contribute with information on the genomes of two commercial strains that are broadly applied to soybean crops in the tropics. B. japonicum CPAC 15 (=SEMIA 5079) is outstanding in its saprophytic capacity and competitiveness, whereas B. diazoefficiens CPAC 7 (=SEMIA 5080) is known for its high efficiency in fixing nitrogen. Both are well adapted to tropical soils. The genomes of CPAC 15 and CPAC 7 were compared to each other and also to those of B. japonicum USDA 6T and B. diazoefficiens USDA 110T. Results: Differences in genome size were found between species, with B. japonicum having larger genomes than B. diazoefficiens. Although most of the four genomes were syntenic, genome rearrangements within and between species were observed, including events in the symbiosis island. In addition to the symbiotic region, several genomic islands were identified. Altogether, these features must confer high genomic plasticity that might explain adaptation and differences in symbiotic performance. It was not possible to attribute known functions to half of the predicted genes.

Characterization of Nudix Hydrolases: a Utilitarian
CHARACTERIZATION OF NUDIX HYDROLASES: A UTILITARIAN SUPERFAMILY OF ENZYMES By Andres Hernandez de la Peña A dissertation submitted to the Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland August, 2015 Abstract The present work details the structural and enzymatic characterization of Nudix hydrolases from three different organisms – Bdellovibrio bacteriovorus, Mycobacterium tuberculosis, and Tetrahymena thermophila. Each of these Nudix enzymes presents unique questions about their physiological function within their organism which are answered with a combination of structural biology, genetic manipulation, enzyme kinetics, and a wide range of protein assays. We demonstrate that RenU, from M. tuberculosis, is part of Redox Homeostasis Control System (RHOCS), which senses and regulates NADH concentrations. This control systems involves two other proteins, the serine/threonine protein kinase G (pknG) and the L13 ribosomal subunits, without which the bacterium fails to evade lysosomal delivery and falls prey to the oxidative arsenal of the macrophage host. Bd-NDPSase, a Nudix enzyme encoded by the B. bacteriovorus gene BD3179, localizes to the periplasmic space of the bacterium and hydrolyses at least four nucleoside diphosphate sugars in vitro. Through atomic-resolution models from X-ray diffraction, we identified a motif that differentiates this hydrolase from the similar, but more substrate specific, ADP- ribose hydrolase from E. coli. Lastly, we show that Nud1p from T. thermophila is a member of the Ezl1p complex, the histone methyltransferase Polycomb Group homologue of this protozoan. With the use of in vitro enzymatic assays we show, in addition, that Nu1dp hydrolyses CoA preferentially over acetyl-CoA and other nucleoside derivatives.

James, University of California, Irvine, CA, and approved December 4, 2007 (received for review August 27, 2007) We demonstrate the presence of an alternate metabolic pathway We previously reported that mosquitoes dispose of toxic for urea synthesis in Aedes aegypti mosquitoes that converts uric ammonia through glutamine (Gln) and proline (Pro) synthesis, acid to urea via an amphibian-like uricolytic pathway. For these along with excretion of ammonia, uric acid, and urea (20). By studies, female mosquitoes were fed a sucrose solution containing using labeled isotopes and mass spectrometry techniques (21), 15 15 15 15 15 NH4Cl, [5- N]-glutamine, [ N]-proline, allantoin, or allantoic we have recently determined how the N from NH4Cl is acid. At 24 h after feeding, the feces were collected and analyzed incorporated into the amide side chain of Gln, and then into Pro, in a mass spectrometer. Specific enzyme inhibitors confirmed that in Ae. aegypti (22). In the present article we demonstrate that the 15 15 15 mosquitoes incorporate N from NH4Cl into [5- N]-glutamine nitrogen of the amide group of Gln contributes to uric acid and use the 15N of the amide group of glutamine to produce synthesis in mosquitoes and, surprisingly, that uric acid can be 15 labeled uric acid.
