Project description:The goal of our present work was to understand the influence parvovirus B19 infection may have on the thyroid hormone signaling pathway, as well as the nuclear receptors (NR) pathway overall. We demonstrated that B19 infection of CD36+ erythroid progenitor cells leads to downregulation of the thyroid hormone receptor α isoform. In addition to that we have shown that B19 infection modulates the expression of other members of the NR superfamily such as estrogen and retinoid receptors. CD36+ cells (StemCell Technologies) were mock-infected or infected with B19, 48 hours post infection cells were collected, total RNA was isolated, and cDNA was obtained as described above. TaqMan® array human nuclear receptors fast 96-well plates obtained from Applied Biosystems (Carlsbad, CA) were utilized in order to assess the differences of 92 nuclear receptors’ expression in mock- and B19-infected CD36+ cells. Relative quantity (RQ) values were calculated using the 2-ΔΔCt method.

Project description:Human parvovirus B19 (B19V) infection can cause transient aplastic crisis, persistent viremia, and pure red-cell aplasia. In fetuses, B19V infection can result in non-immune hydrops fetalis and fetal death. To systematically investigate the interaction between B19V and erythoid progenetor cells (EPC), microarray was applied to systematically analyze the dynamic transcriptome of CD36+ EPCs during B19V infection.

Project description:Since targeting of specific pathogenic pathways may be more efficient than current unspecific heart failure treatment, we obtained genomewide expression profiles of a DCM subtype characterized by cardiac inflammation (DCMi) in association with parvovirus B19. This study was entirely based on RNA isolated from endomyocardial biopsies so far only rarely used for genomic expression profiling. Keywords: disease state analysis

Project description:Kynureninase is a member of a large family of catalytically diverse but structurally homologous pyridoxal 5'-phosphate (PLP) dependent enzymes known as the aspartate aminotransferase superfamily or alpha-family. The Homo sapiens and other eukaryotic constitutive kynureninases preferentially catalyze the hydrolytic cleavage of 3-hydroxy-l-kynurenine to produce 3-hydroxyanthranilate and l-alanine, while l-kynurenine is the substrate of many prokaryotic inducible kynureninases. The human enzyme was cloned with an N-terminal hexahistidine tag, expressed, and purified from a bacterial expression system using Ni metal ion affinity chromatography. Kinetic characterization of the recombinant enzyme reveals classic Michaelis-Menten behavior, with a Km of 28.3 +/- 1.9 microM and a specific activity of 1.75 micromol min-1 mg-1 for 3-hydroxy-dl-kynurenine. Crystals of recombinant kynureninase that diffracted to 2.0 A were obtained, and the atomic structure of the PLP-bound holoenzyme was determined by molecular replacement using the Pseudomonas fluorescens kynureninase structure (PDB entry 1qz9) as the phasing model. A structural superposition with the P. fluorescens kynureninase revealed that these two structures resemble the "open" and "closed" conformations of aspartate aminotransferase. The comparison illustrates the dynamic nature of these proteins' small domains and reveals a role for Arg-434 similar to its role in other AAT alpha-family members. Docking of 3-hydroxy-l-kynurenine into the human kynureninase active site suggests that Asn-333 and His-102 are involved in substrate binding and molecular discrimination between inducible and constitutive kynureninase substrates.
