Sensitization To Self (Virus) Antigen By In Situ Expression Of Murine Interferon-Gamma., Myung-Shik Lee, Matthias Von Herrath, Hans Reiser, Michael B.A. Oldstone, Nora Sarvetnick Feb 1995

Sensitization To Self (Virus) Antigen By In Situ Expression Of Murine Interferon-Gamma., Myung-Shik Lee, Matthias Von Herrath, Hans Reiser, Michael B.A. Oldstone, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Autoimmune disease results from inflammatory destruction of tissues by aberrant self-reactive lymphocytes. We studied the autoimmune potential of T lymphocytes immunologically ignorant of viral antigens acting as self antigens and whether the host defense molecule IFN-gamma could stimulate these cells to cytotoxic competency. For this purpose, we produced double transgenic mice expressing pancreatic IFN-gamma as well as lymphocytic choriomeningitis virus (LCMV) nucleoprotein (NP) or glycoprotein (GP) antigen. 100% of the NP+/IFN-gamma+ mice became diabetic before 2 mo of age, while none of the NP single transgenic littermates and only 10% of IFN-gamma single transgenic littermates did. Strikingly, NP+/IFN-gamma+ mice spontaneously …

Journal Articles: Regenerative Medicine

Abnormal humoral responses toward motor end plate constituents in muscle induce myasthenia gravis (MG). To study the etiology of this disease, and whether it could be induced by host defense molecules, we examined the consequences of interferon (IFN) gamma production within the neuromuscular junction of transgenic mice. The transgenic mice exhibited gradually increasing muscular weakness, flaccid paralysis, and functional disruption of the neuromuscular junction that was reversed after administration of an inhibitor of acetylcholinesterase, features which are strikingly similar to human MG. Furthermore, histological examination revealed infiltration of mononuclear cells and autoantibody deposition at motor end plates. Immunoprecipitation analysis indicated …

Complementary Gradients In Expression And Binding Of Elf-1 And Mek4 In Development Of The Topographic Retinotectal Projection Map, Masaru Nakamoto Jan 1995

Complementary Gradients In Expression And Binding Of Elf-1 And Mek4 In Development Of The Topographic Retinotectal Projection Map, Masaru Nakamoto

Biology Faculty Publications

Topographic maps with a defined spatial ordering of neuronal connections are a key feature of brain organization. Such maps are believed to develop in response to complementary position-specific labels in presynaptic and postsynaptic fields. However, the complementary labeling molecules are not known. In the well studied visual map of retinal axons projecting to the tectum, the labels are hypothesized to be in gradients, without needing large numbers of cell-specific molecules. We recently cloned ELF-1 as a ligand for Eph family receptors. Here, RNA hybridization shows matching expression gradients for ELF-1 in the tectum and its receptor Mek4 in the retina. …

Thirty one compounds (phenol; its 12 possible monohalo analogues; 18 nitrophenols (2- and 4-nitrophenols, 4-, 5-, and 6-halo-2-nitrophenols, 3-halo-4-nitrophenols)) were tested for antifungal activity against six fungi (A. niger, A. oryzae, M. verrucaria, T. viride, M. cirinelloides, and T. mentagrophytes) in Sabouraud dextrose broth. The two most fungitoxic compounds of those studied were 5-fluoro- and 5-iodo-2-nitrophenols which inhibited all the fungi at concentrations under 10 μg/ml. 6-Iodo-2-nitrophenol inhibited five fungi at a concentration below 10 μg/ml and M. cirinelloides at 10- 100 μg/ ml

Chemistry Faculty Publications

Methods have been systematized for preparing substituted 8-quinolinols. The 5 and 7 positions are those available for electrophilic substitution. The entry position of the electrophile can be controlled by controlling the prototropic form of the 8-quinolinol. Under acidic conditions the 5 position is attacked first and under basic conditions the electrophile is directed to the 7 position. Iodination is the reverse. Regiospecificity also can be achieved by blocking the 5 or 7 position with sulfonic acid groups followed by addition of the electrophile and deblocking by acid hydrolysis, providing the new substituent is stable to acid hydrolysis. When compounds containing …

Gautam Sarath Publications

Steady-state kinetic analyses were performed on the non-phosphorylated, in vitro phosphorylated and phosphorylation-site mutant (Ser8→Asp) forms of purified recombinant sorghum C4 phosphoenolpyruvate (P-pyruvate) carboxylase (EC 4.1.1.3 1) containing an intact N-terminus. Significant differences in certain kinetic parameters were observed between these three enzyme forms when activity was assayed at a suboptimal but near-physiological pH (7.3), but not at optimal pH (8.0). Most notably, at pH 7.3 the apparent Ki/ for the negative allosteric effector l-malate was 0.17 mM, 1.2 mM and 0.45 mM while the apparent Ka for the positive allosteric effector glucose 6-phosphate (Glc6P) at 1mM …

A Small Modified Hammerhead Ribozyme And Its Conformational Characteristics Determined By Mutagenesis And Lattice Calculation, Brooke Lustig, N H. Lin, S M. Smith, R L. Jernigan, K.-T Jeang Jan 1995

A Small Modified Hammerhead Ribozyme And Its Conformational Characteristics Determined By Mutagenesis And Lattice Calculation, Brooke Lustig, N H. Lin, S M. Smith, R L. Jernigan, K.-T Jeang

Faculty Publications, Chemistry

A prototypic hammerhead ribozyme has three helices that surround an asymmetrical central core loop. We have mutagenized a hammerhead type ribozyme. In agreement with previous studies, progressive removal of stem-loop II from a three stemmed ribozyme showed that this region is not absolutely critical for catalysis. However, complete elimination of stem II and its loop did reduce, but did not eliminate, function. In a stem-loop II-deleted ribozyme, activity was best preserved when a purine, preferably a G, was present at position 10.1. This G contributed to catalysis irregardless of its role as either one part of a canonical pair with …

Fish Analysis On Spontaneously Arising Micronuclei In The Icf Syndrome, Michael W. Stacey, M. S. Bennett, M. Hulten Jan 1995

Fish Analysis On Spontaneously Arising Micronuclei In The Icf Syndrome, Michael W. Stacey, M. S. Bennett, M. Hulten

Bioelectrics Publications

The ICF syndrome is a rare disorder where patients show undercondensation of the heterochromatic blocks of chromosomes 1, 9, and 16 along with variable immunodeficiency. The undercondensation of the heterochromatic block appears to be restricted to a portion of PHA stimulated T cells. Patients with this syndrome also show an increase in micronuclei formation. We have used dual colour FISH to investigate the chromosomal content of these micronuclei in PHA stimulated peripheral blood cultures, an EBV transformed B cell line, and also micronuclei observed in vivo from peripheral blood smears. Chromosome 1 appears to be present in a higher proportion …

Elimination Of Dissolved Sulfide Interference In The Flow-Injection Determination Of Sigma-Co2 By Addition Of Molybdate, Rigel L. Lustwerk, David J. Burdige Jan 1995

Elimination Of Dissolved Sulfide Interference In The Flow-Injection Determination Of Sigma-Co2 By Addition Of Molybdate, Rigel L. Lustwerk, David J. Burdige

OES Faculty Publications

A previously described flow injection method for the analysis of ΣCO2 included the addition of ZnCl2 to some samples before analysis in order to precipitate dissolved sulfide (which interferes with the method) as ZnS. However, the use of Zn2+ in samples with high concentrations of dissolved sulfide causes the coprecipitation of ZnCO3, and in our experience with this technique, ZnCO3 also precipitates even in the absence of dissolved sulfide. The addition of molybdate effectively complexes dissolved sulfide without interfering with the determination of ΣCO2 by this technique.

The Development Of Methodology For The Examination Of Interhelical Distances Of A Bacteriorhodopsin Mutant Using The Heterobifunctional Cross-Linker 4-(N-Maleimido) Benzophenone, Tracie L. Bishop Jan 1995

The Development Of Methodology For The Examination Of Interhelical Distances Of A Bacteriorhodopsin Mutant Using The Heterobifunctional Cross-Linker 4-(N-Maleimido) Benzophenone, Tracie L. Bishop

MUSC Theses and Dissertations

Bacteriorhodopsin (BR) is the sole protein found in the purple membrane of Halobacteria salinarium. The chromophore of BR, all-trans retinal, is bound to the apoprotein of BR via a protonated Schiff base linkage to the E-amino group of Lys216. The protonated all-trans retinal isomerizes to the deprotonated I3-cis retinal upon the absorption of light. This light induced chromophore isomerization triggers a cycle of proton pumping from the cytosol to the extracellular side of the membrane (one H+ per trans to cis isomerization). This proton pumping creates a gradient across the membrane which can be used by the bacterium to synthesize …

In Vivo Regulation Of Wheat-Leaf Phosphoenolpyruvate Carboxylase By Reversible Phosphorylation, Stephen M. G. Duff, Raymond Chollet Jan 1995

In Vivo Regulation Of Wheat-Leaf Phosphoenolpyruvate Carboxylase By Reversible Phosphorylation, Stephen M. G. Duff, Raymond Chollet

Department of Biochemistry: Faculty Publications

Regulation of C3 phosphoenolpyruvate carboxylase (PEPC) and its protein-serine/threonine kinase (PEPC-PK) was studied in wheat (Trificum aesfivum) leaves that were excised from low-N-grown seedlings and subsequently illuminated and/or supplied with 40 mM KNO3. The apparent phosphorylation status of PEPC was assessed by its sensitivity to i-malate inhibition at suboptimal assay conditions, and the activity state of PEPC-PK was determined by the in vitro 32P labeling of purified maize dephospho-PEPC by [y32PIATP/ Mg. lllumination (±NO3-) for 1 h led to about a 4.5-fold increase in the 50% inhibition constant for i-malate, which …

Dephosphorylation Of The Thylakoid Membrane Light-Harvesting Complex-Ii By A Stromal Protein Phosphatase, Mark E. Hammer, Gautam Sarath, John Markwell Jan 1995

Dephosphorylation Of The Thylakoid Membrane Light-Harvesting Complex-Ii By A Stromal Protein Phosphatase, Mark E. Hammer, Gautam Sarath, John Markwell

Gautam Sarath Publications

Light-harvesting complex-II (LHC-II) phosphatase activity has generally been examined in the intact thylakoid membrane. A recent report of peptide-phosphatase activity associated with the chloroplast stromal fraction (Hammer, M.E et al. (1995) Photosynth Res 44:107–115) has led to the question of whether this activity is capable of dephosphorylating membrane-bound LHC-II. To this end, heat-treated thylakoid membranes were examined as a potential LHC-II phosphatase substrate. Following incubation of the thylakoid membrane at 60 °C for 15 min, the endogenous protein phosphatase and kinase activities were almost eliminated. Heat-inactivated phosphomembranes exhibited minimal dephosphorylation of the light harvesting complex-II. Peptide-phosphatase activities isolated from the …

New Optical Cell Design For Laser Flash Photolysis Studies In Supercritical Fluids, Steven R. Goates, Milton L. Lee, Qin Ji, Edward M. Eyring, Rudi Van Eldik, Kedika Bal Reddy

Faculty Publications

A high-pressure optical cell has been designed that achieves an effective separation between the chemical sample and the pressurizing medium and system. This design limits possible sample contamination and catalytic effects under supercritical fluid sample conditions. Laser flash photolysis experiments were carried out on molybdenum hexacarbonyl dissolved in supercritical CO2. The thermal ring closure reaction of the species Mo(CO)5L, where L is 2,2- bipyridine was found to proceed at rates comparable to those measured previously in liquid benzene or toluene. Much larger activation volumes were found for the reaction in supercritical CO2 than in liquid toluene.

School of Medical Diagnostics & Translational Sciences Publications

Large terminal fragments of human chromosomes 2p, 6q, 8q, 12q, and 18q were cloned using yeast artificial chromosomes (YACs). RecA-assisted restriction endonuclease (RARE) cleavage analysis of genomic DNA samples from 11 unrelated individuals using YAC-derived probes confirmed the telomeric localizations of the half-YACs studied. The cloned Fragments provide telomeric closure of maps for the respective chromosome arms and will supply the reagents needed for analyzing and sequencing these distal subtelomeric regions.

Consistencies Of Individual Dna Base-Amino Acid Interactions In Structures And Sequences, Brooke Lustig, R L. Jernigan

Faculty Publications, Chemistry

Amino acid-amino acid interaction energies have been derived from crystal structure data for a number of years. Here is reported the first derivation of normalized relative interaction from binding data for each of the four bases interacting with a specific amino acid, utilizing data from combinatorial multiplex ONA binding of zinc finger domains [Desjarlais, J. R. and Berg, J. M. (1994) Proc. Natl. Acad. Sci. USA, 91, 11099–11103]. The five strongest Interactions are observed for lysine-guanine, lysine-thymine, arginine- guanine, aspartic acid-cytosine and asparagineadenine. These rankings for interactions with the four bases appear to be related to base-amino acid partial charges. …

Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma Dec 1994

Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma

Electronic Theses and Dissertations

The hypothesis that antioxidant vitamins (ascorbate and tocopherols) along with urate protect blood plasma lipids from oxidation was tested. Dietary fat is also an important factor influencing plasma lipid peroxidation. The purpose of this study was to investigate the role of plasma antioxidants and dietary fat on low density lipoprotein (LDL) and plasma lipid oxidation. In the first part of this study, we compared the ability of urate and ascorbate to protect human LDL from in vitro oxidation. LDL oxidation was initiated by 15 mM of a water soluble azo-initiator in the presence or absence of ascorbate or urate. The …
