Characterization of the avian GLUT1 glucose transporter: differential regulation of GLUT1 and GLUT3 in chicken embryo fibroblasts.
(East Carolina University, 1995-11)
Vertebrate cells that are transformed by oncogenes such as v-src or are stimulated by mitogens have increased rates of glucose uptake. In rodent cels, the mechanisms whereby glucose transport is up-regulated are well ...
Cloning and characterization of the endogenous cephalosporinase gene, cepA, from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases.
(East Carolina University, 1993-11)
Bacteroides frgiglis CS30 is a clinical isolate resistant to high concentrations of benzylpenicillin and cephaloridine but not to cephamycin or penem antibiotics. beta-Lactam resistance is mediated by a chromosomally encoded ...
Quinolone signaling in the cell-to-cell communication system of Pseudomonas aeruginosa
(East Carolina University, 1999-09-28)
Numerous species of bacteria use an elegant
regulatory mechanism known as quorum sensing to control
the expression of specific genes in a cell-density dependent
manner. In Gram-negative bacteria, quorum sensing ...
Characterization of a Peroxide-Resistant Mutant of the Anaerobic Bacterium Bacteroides fragilis
(East Carolina University, 1998-11)
A Bacteroides fragilis mutant resistant to hydrogen peroxide and alkyl peroxide was isolated by enrichment
in increasing concentrations of hydrogen peroxide. The mutant strain was constitutively resistant to 100 mM
H2O2 ...
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 ...
Molecular basis for the immunosuppressive action of stearic acid on T cells.
(East Carolina University, 1990-07)
Studies were performed to determine the mechanism by which stearic acid (18: 0) selectively inhibits T-dependent immune responses in vitro. Incubation of mitogen-activated B and T cells with 18:0 resulted in dissimilar ...
The ornithine decarboxylase gene odc is required for alcaligin siderophore biosynthesis in Bordetella spp.: putrescine is a precursor of alcaligin.
(East Carolina University, 1996-01)
Chromosomal insertions defining Bordetella bronchiseptica siderophore phenotypic complementation group III mutants BRM3 and BRM5 were found to reside approximately 200 to 300 bp apart by restriction mapping of cloned genomic ...
Bordetella pertussis fur gene restores iron repressibility of siderophore and protein expression to deregulated Bordetella bronchiseptica mutants.
(East Carolina University, 1995-01)
We report the isolation and preliminary phenotypic characterization of manganese-resistant Bordetella bronchiseptica mutants with respect to deregulation of siderophore and iron-regulated protein expression. The fur gene ...
Familial cryptic translocation resulting in Angelman syndrome:implications for imprinting or location of the Angelman gene?
(East Carolina University, 1996-04)
Angelman syndrome (AS) is associated with a loss of maternal genetic information, which typically occurs as a result of a deletion at 15ql1-q13 or paternal uniparental disomy of chromosome 15. We report a patient with AS ...
Method for the microbial decontamination of blood platelets
(1999-04-06)
A method for inactivating microbiological contaminants in a human blood platelet preparation is disclosed. The method comprises, first, providing blood platelets, particularly human blood platelets, suspected of being ...
