A two-component response regulator, gltR, is required for glucose transport activity in Pseudomonas aeruginosa PAO1.
(East Carolina University, 1996-10)A 729-bp open reading frame (gltR) was identified in Pseudomonas aeruginosa PAO1 that encodes a product homologous to the two-component response regulator family of proteins. Disruption of gltR caused loss of glucose ... -
Lipid mediators of insulin resistance: ceramide signalling down-regulates GLUT4 gene transcription in 3T3-L1 adipocytes.
(East Carolina University, 1996-10-01)We have previously demonstrated that chronic exposure of 3T3- L1 adipocytes to tumour necrosis factor-α (TNF) resulted in a marked decrease (~90%) in cellular GLUT4 (insulin-responsive glucose transporter) mRNA content as ... -
Oxidative stress response in an anaerobe, Bacteroides fragilis: a role for catalase in protection against hydrogen peroxide.
(East Carolina University, 1996-12)Survival of Bacteroides fragilis in the presence of oxygen was dependent on the ability of bacteria to synthesize new proteins, as determined by the inhibition of protein synthesis after oxygen exposure. The B. fragilis ... -
Comparison of identifications of human and animal source gram-negative bacteria by API 20E and crystal E/NF systems.
(East Carolina University, 1997-01)This study compared the abilities of API 20E and BBL Crystal E/NF identification systems to correctly identify human and animal source gram-negative bacilli of known identifications, as provided by the American Type Culture ... -
Inhibition by rapamycin of ornithine decarboxylase and epithelial cell proliferation in intestinal IEC-6 cells in culture
(East Carolina University, 1997-02)1 Induction of the enzyme ornithine decarboxylase (ODC) appears to be controlled primarily at the level of ODC mRNA translation. The immunosuppressant drug, rapamycin, blocked the induction of ODC in response to serum ... -
Ectopic expression of Hel-N1, an RNA-binding protein, increases glucose transporter (GLUT1) expression in 3T3-L1 adipocytes.
(East Carolina University, 1997-02)3T3-L1 preadipocytes ectopically expressing the mammalian RNA-binding protein Hel-N1 expressed up to 10-fold more glucose transporter (GLUT1) protein and exhibited elevated rates of basal glucose uptake. Hel-N1 is a member ... -
Alveolar macrophage priming by intravenous administration of chitin particles, polymers of N-acetyl-D-glucosamine, in mice
(East Carolina University, 1997-03)Intravenous (i.v.) administration of phagocytosable chitin particles (1 to 10 mm) in C57BL/6 mice and SCID mice primed alveolar macrophages (Mf) within 3 days to yield up to a 50-fold increase in their oxidative burst when ... -
Hypothesis for induction and propagation of chemical sensitivity based on biopsy studies.
(East Carolina University, 1997-03)The reactive airways dysfunction syndrome (RADS), the reactive upper airways dysfunction syndrome (RUDS), the sick building syndrome (SBS), and the multiple chemical sensitivity syndrome (MCS) are overlapping disorders ... -
The transneuronal spread phenotype of herpes simplex virus type 1 infection of the mouse hind footpad.
(East Carolina University, 1997-03)The mouse hind footpad inoculation model has served as a standard laboratory system for the study of the neuropathogenesis of herpes simplex virus type 1 (HSV-1) infection. The temporal and spatial distribution of viral ... -
The Bacteroides mobilizable transposon Tn4555 integrates by a site-specific recombination mechanism similar to that of the gram-positive bacterial element Tn916
(East Carolina University, 1997-04)The Bacteroides mobilizable transposon Tn4555 is a 12.2-kb molecule that encodes resistance to cefoxitin. Conjugal transposition is hypothesized to occur via a circular intermediate and is stimulated by coresident tetracycline ... -
Method of treating adenosine depletion
(1997-08-26)A method of treating adenosine depletion in a subject in need of such treatment is disclosed. The method comprises administering to the subject folinic acid or a pharmaceutically acceptable salt thereof in an amount effective ... -
A composition comprising nerve growth factor and 2-amino-1,1,3-tricyano-1-propene useful for the induction, stimulation, and maintenance of nerve growth, and methods of potentiating choline O-acetyltransferase and tyrosine hydroxylase by 2-amino-1,1,3-tricyano-1-propene are disclosed.
(1997-09-09)A composition comprising nerve growth factor and 2-amino-1,1,3-tricyano-1-propene useful for the induction, stimulation, and maintenance of nerve growth, and methods of potentiating choline O-acetyltransferase and tyrosine ... -
Regulation of Bacteriodes fragilis katB mRNA by oxidative stress and carbon limitation.
(East Carolina University, 1997-11)Regulation of the katB catalase gene in the anaerobic bacterium Bacteroides fragilis was studied. Northern blot hybridization analyses revealed that katB was transcribed as an approximately 1.6-kb monocistronic mRNA. The ... -
The pseudorabies virus UL28 protein enters the nucleus after coexpression with the herpes simplex virus UL15 protein
(East Carolina University, 1997-12)Herpesvirus DNA is packaged into capsids in the nuclei of infected cells in a process requiring at least six viral proteins. Of the proteins required for encapsidation of viral DNA, UL15 and UL28 are the most conserved among ... -
Tinigible Body Macrophages in Regulation of Germinal Center Reactions
(East Carolina University, 1998)Tingible body macrophages (TBM), long thought simply as scavengers of apoptotic lymphocytes, are located in the unique microenvironment of germinal centers in close proximity to antigen-retaining follicular dendritic cells ... -
The Transfer Origin for Bacteroides Mobilizable Transposon Tn4555 Is Related to a Plasmid Family from Gram-Positive Bacteria
(East Carolina University, 1998-01)Conjugal transfer of Bacteroides mobilizable transposon Tn4555 was examined with an Escherichia coli-based assay system. It was shown that mobilization required the cis-acting oriTTn region and that the Tn4555 mobATn gene ... -
