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 ... -
Motility and chemotaxis in the Lyme disease spirochete Borrelia burgdorferi : role in pathogenesis
(East Carolina University, 2016-08-18)Lyme disease is the most prevalent vector-borne disease in United States and is caused by the spirochete Borrelia burgdorferi. The disease is transmitted from an infected Ixodes scapularis tick to a mammalian host. B. ... -
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 ... -
Multifaceted roles of GSK-3 and Wnt/β-catenin in hematopoiesis and leukemogenesis: opportunities for therapeutic intervention
(2014-01)Glycogen synthase kinase-3 (GSK-3) is well documented to participate in a complex array of critical cellular processes. It was initially identified in rat skeletal muscle as a serine/threonine kinase that phosphorylated ... -
Murine mesothelin: characterization, expression, and inhibition of tumor growth in a murine model of pancreatic cancer
(2016-03)Background Mesothelin has attracted much interest as a tumor specific antigen; it has been reported to promote tumor development and to be a good target for cancer treatment. Most studies to date have used human mesothelin ... -
Mutations and Deregulation of Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR Cascades Which Alter Therapy Response
(2012-09)The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Certain components of these pathways, RAS, NF1, BRAF, ... -
Nectin like-5 overexpression correlates with the malignant phenotype in cutaneous melanoma
(2012-08)NECL-5 is involved in regulating cell–cell junctions, in cooperation with cadherins, integrins and platelet-derived growth factor receptor, that are essential for intercellular communication. Its role in malignant ... -
Neuroantigen-specific, tolerogenic vaccines: GM-CSF is a fusion partner that facilitates tolerance rather than immunity to dominant self-epitopes of myelin in murine models of experimental autoimmune encephalomyelitis (EAE)
(2011)Background Vaccination strategies that elicit antigen-specific tolerance are needed as therapies for autoimmune disease. This study focused on whether cytokine-neuroantigen (NAg) fusion proteins could inhibit disease ... -
Novel Combination of Sorafenib and Celecoxib Provides Synergistic Anti-Proliferative and Pro-Apoptotic Effects in Human Liver Cancer Cells
(2013)Molecular targeted therapy has shown promise as a treatment for advanced hepatocellular carcinoma (HCC). Sorafenib, a multikinase inhibitor, recently received FDA approval for the treatment of advanced HCC. However, although ... -
A novel DAG-dependent mechanism links PKCa and Cyclin B1 regulating cell cycle progression
(2014-11)Through the years, different studies showed the involvement of Protein Kinase C (PKC) in cell cycle control, in particular during G1/S transition. Little is known about their role at G2/M checkpoint. In this study, using ... -
The novel dual PI3K/mTOR inhibitor NVP-BGT226 displays cytotoxic activity in both normoxic and hypoxic hepatocarcinoma cells
(2015-07)Hepatocellular carcinoma (HCC) is one of the most common lethal human malignancies worldwide and its advanced status is frequently resistant to conventional chemotherapeutic agents and radiation. We evaluated the cytotoxic ... -
NOVEL ROLE OF HUMAN T-CELL LEUKEMIA VIRUS TYPE-1 ENCODED PROTEIN HBZ IN VIRAL TRANSMISSION THROUGH CELL-TO-CELL CONTACT
(East Carolina University, 2017-04-28)The complex retrovirus Human T cell leukemia virus type I (HTLV-1) is the etiologic agent of several diseases, including Adult T cell leukemia (ATL), a fatal hematological malignancy that affects mainly CD4+ T-cells. Freshly ... -
Nucleotide sequence of the phosphoprotein (P) gene of Newcastle disease virus (strain Beaudette C).

The nucleotide sequence of the Pseudomonas aeruginosa pyrE-crc-rph region and the purification of the crc gene product.
(East Carolina University, 1996-10)The gene (crc) responsible for catabolite repression control in Pseudomonas aeruginosa has been cloned and sequenced. Flanking the crc gene are genes encoding orotate phosphoribosyl transferase (pyrE) and RNase PH (rph). ... -
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 ... -
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 ... -
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 ... -
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 ... -
