Transplantation of GABAergic Neurons but not Astrocytes Induces Recovery of Sensorimotor Function in the Traumatically Injured Brain
(East Carolina University, 2007-04-16)
Embryonic stem (ES) cells have been investigated in many animal models of injury and disease.
However, few studies have examined the ability of pre-differentiated ES cells to improve functional
outcome following traumatic ...
Overcoming resistance to molecularly targeted anticancer therapies: rational drug combinations based on EGFR and MAPK inhibition for solid tumours and haematologic malignancies
(East Carolina University, 2007-06)
Accumulating evidence suggests that cancer can be envisioned as a "signaling disease", in which alterations in the cellular genome affect the expression and/or function of oncogenes and tumour suppressor genes. This ...
Cloning and characterization of a conjugated bile acid hydrolase gene from Clostridium perfringens.
(East Carolina University, 1995-07)
The gene encoding a conjugated bile acid hydrolase (CBAH) from Clostridium perfringens 13 has been cloned and expressed in Escherichia coli, and its nucleotide sequence has been determined. Nucleotide and predicted amino ...
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 ...
Regulation of Pseudomonas Quinolone Signal Synthesis in Pseudomonas aeruginosa
(East Carolina University, 2005-07)
Pseudomonas aeruginosa is an opportunistic pathogen that causes chronic lung infections in cystic fibrosis patients and is a major source of nosocomial infections. This bacterium controls many virulence factors by using ...
Enhancement of Antibodies to the Human Immunodeficiency Virus Type 1 Envelope by Using the Molecular Adjuvant C3d
(East Carolina University, 2003-02)
DNA vaccines expressing the envelope (Env) protein of the human immunodeficiency virus have been relatively ineffective at generating high-titer, long-lasting, neutralizing antibodies in a variety of animal models. In this ...
Identification and Characterization of alcR, a Gene Encoding an AraC-Like Regulator of Alcaligin Siderophore Biosynthesis and Transport in Bordetella pertussis and Bordetella bronchiseptica
(East Carolina University, 1998-02)
A Bordetella bronchiseptica iron transport mutant was isolated following an enrichment procedure based on streptonigrin resistance. The mutant displayed a growth defect on iron-restricted medium containing ferric alcaligin ...
Identification and characterization of iron-regulated Bordetella pertussis alcaligin siderophore biosynthesis genes.
(East Carolina University, 1996-08)
Bordetella bronchiseptica mutants BRM1, BRM6, and BRM9 fail to produce the native dihydroxamate siderophore alcaligin. A 4.5-kb BamHI-SmaI Bordetella pertussis genomic DNA fragment carried multiple genes required to restore ...
Functions Required for Extracellular Quinolone Signaling by Pseudomonas aeruginosa
(East Carolina University, 2002-12)
A set of 30 mutants exhibiting reduced production of the phenazine poison pyocyanin were isolated following transposon mutagenesis of Pseudomonas aeruginosa PAO1. The mutants could be subdivided into those with defects in ...
Transcriptional Activation of Bordetella Alcaligin Siderophore Genes Requires the AlcR Regulator with Alcaligin as Inducer
(East Carolina University, 2001-01)
Genetic and biochemical studies have established that Fur and iron mediate repression of Bordetella alcaligin siderophore system (alc) genes under iron-replete nutritional growth conditions. In this study, transcriptional ...
