Enforced expression of HoxA9 in b-lineage all promotes survival and proliferation of leukemic cells
(East Carolina University, 2009)
HoxA9 is frequently overexpressed in acute myeloid leukemia, myelodysplastic syndrome and a subset of acute lymphoblastic leukemia. In mouse models, HoxA9 has been shown to promote leukemogenesis. In spite of a seemingly ...
The Redox-Sensitive Transcriptional Activator OxyR Regulates the Peroxide Response Regulon in the Obligate Anaerobe Bacteroides fragilis
(East Carolina University, 2000-09)
The peroxide response-inducible genes ahpCF, dps, and katB in the obligate anaerobe Bacteroides fragilis are
controlled by the redox-sensitive transcriptional activator OxyR. This is the first functional oxidative ...
Anti-cancer drug induced neurotoxicity and identification of Rho pathway signaling modulators as potential neuroprotectants
(East Carolina University, 2008-07)
Many chemotherapy drugs are known to cause significant clinical neurotoxicity, which can result in the early cessation of treatment. To identify and develop more effective means of neuroprotection it is important to ...
Anti-growth properties of BAY 41-2272 in vascular smooth muscle cells
(East Carolina University, 2009-02)
Vascular smooth muscle (VSM) growth is integral in the pathophysiology of blood vessel diseases, and identifying approaches that have capacity to regulate VSM growth is critically essential. Cyclic nucleotide signaling has ...
Amyloid-beta peptide A beta p3-42 affects early aggregation of full-length A beta 1-42
(East Carolina University, 2009-05)
The major amyloid beta (Aβ) peptides found in the brain of familial and late onset Alzheimer’s
disease include the full-length Aβ1-42 and N-terminally truncated, pyroglutamylated peptides
Aβp3-42 and Aβp11-42. The ...
Opsonized Virulent Brucella abortus Replicates within Nonacidic, Endoplasmic Reticulum-Negative, LAMP-1-Positive Phagosomes in Human Monocytes
(East Carolina University, 2005-06)
Cells in the Brucella spp. are intracellular pathogens that survive and replicate within host monocytes. Brucella maintains persistent infections in animals despite the production of high levels of anti-Brucellaspecific ...
Two Distinct Pathways Supply Anthranilate as a Precursor of the Pseudomonas Quinolone Signal
(East Carolina University, 2007-05)
Pseudomonas aeruginosa is an opportunistic pathogen that causes serious infections in immunocompromised patients and those with cystic fibrosis (CF). This gram-negative bacterium uses multiple cell-to-cell signals to control ...
A Multicomponent System Is Required for Tetracycline-Induced Excision of Tn4555
(East Carolina University, 2004-01)
Bacteroides spp. are the predominant organisms in the intestinal tract, and they also are important opportunistic
pathogens. Antibiotic therapy of Bacteroides infections often is complicated by the prevalence of
drug-resistant ...
Characterization of Bacteroides fragilis Hemolysins and Regulation and Synergistic Interactions of HlyA and HlyB
(East Carolina University, 2006-04)
This study describes the presence of 10 hemolysin orthologs in the genome of the opportunistic human anaerobic pathogen Bacteroides fragilis, which is currently classified as a nonhemolytic bacterium. The hemolysins were ...
Autolysis and Autoaggregation in Pseudomonas aeruginosa Colony Morphology Mutants
(East Carolina University, 2002-12)
Two distinctive colony morphologies were noted in a collection of Pseudomonas aeruginosa transposon insertion mutants. One set of mutants formed wrinkled colonies of autoaggregating cells. Suppressor analysis of a subset ...
