Similarity to peroxisomal-membrane protein family reveals that Sinorhizobium and Brucella BacA affect lipid-A fatty acids
(East Carolina University, 2004-04-06)Sinorhizobium meliloti, a legume symbiont, and Brucella abortus, a phylogenetically related mammalian pathogen, both require the bacterial-encoded BacA protein to establish chronic intracellular infections in their respective ... -
Solubility and Bioactivity of the Pseudomonas Quinolone Signal Are Increased by a Pseudomonas aeruginosa-Produced Surfactant
(East Carolina University, 2005-02)Pseudomonas aeruginosa is a gram-negative bacterium that causes serious infections in immunocompromised individuals and cystic fibrosis patients. This opportunistic pathogen controls many of its virulence factors and ... -
Synergistic Proapoptotic Activity of Recombinant Trail Plus the AKT Inhibitor Perifosine in Acute Myelogenous Leukemia Cells
(East Carolina University, 2008-11-15)To potentiate the response of acute myelogenous leukemia (AML) cells to TNF-Related Apoptosis- Inducing Ligand (TRAIL) cytotoxicity, we have examined the efficacy of a combination with perifosine, a novel phosphatidylinositol ... -
Targeting prostate cancer based on signal transduction and cell cycle pathways
(East Carolina University, 2008-06-15)Prostate cancer remains a leading cause of death in men despite increased capacity to diagnose at earlier stages. After prostate cancer has become hormone independent, which often occurs after hormonal ablation therapies, ... -
Targeting the leukemic stem cell: the Holy Grail of leukemia therapy
(East Carolina University, 2009-01)Since the discovery of leukemic stem cells (LSCs) over a decade ago, many of their critical biological properties have been elucidated, including their distinct replicative properties, cell surface phenotypes, their ... -
Targeting the RAF/MEK/ERK, PI3K/AKT and P53 pathways in hematopoietic drug resistance

Thioredoxin Reductase Is Essential for Thiol/Disulfide Redox Control and Oxidative Stress Survival of the Anaerobe Bacteroides fragilis
(East Carolina University, 2007-11)Results of this study showed that the anaerobic, opportunistic pathogen Bacteroides fragilis lacks the glutathione/glutaredoxin redox system and possesses an extensive number of putative thioredoxin (Trx) orthologs. ... -
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 ... -
Transcriptional Analysis of the Bordetella Alcaligin Siderophore Biosynthesis Operon
(East Carolina University, 1998-02)The alc gene cluster of Bordetella pertussis includes three genes, alcA, alcB, and alcC, which are involved in alcaligin siderophore biosynthesis in response to iron starvation. The production of AlcA, AlcB, and AlcC in ... -
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 ... -
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 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 ... -
Unique V3 Loop Sequence Derived from the R2 Strain of HIV-Type 1 Elicits Broad Neutralizing Antibodies
(East Carolina University, 2004-11)DNA vaccines expressing the envelope (Env) of the human immunodeficiency virus type 1 (HIV-1) have been relatively ineffective at generating high-titer, long-lasting, neutralizing antibodies. In this study, DNA vaccines ... -
Upregulation of Human T-Cell Leukemia Virus Type 1 Antisense Transcription by the Viral Tax Protein
(East Carolina University, 2009-02)Several studies have recently demonstrated the existence of human T-cell leukemia virus type 1 (HTLV-1) antisense transcripts, which allow the synthesis of the newly described HBZ protein. Although previous reports have ... -
Using death to one's advantage: HIV modulation of apoptosis
(East Carolina University, 2001-03)Infection by human immunodeficiency virus (HIV) is associated with an early immune dysfunction and progressive destruction of CD4+ T lymphocytes. This progressive disappearance of T cells leads to a lack of immune control ... -
VACCINIA VIRUS O1L VIRULENCE GENE AND PROTEIN LOCALIZATION
(2015)Smallpox killed an estimated 500 million people in the twentieth century alone. Although this fatal disease was eradicated from the world over thirty years ago, its potential use as a bioterrorism agent remains a concern. ... -
