Layered regulation of a pathway capable of altering quinolone production in Pseudomonas aeruginosa
(East Carolina University, 2014)Pseudomonas aeruginosa is a gram negative opportunistic pathogen which commonly infects hospitalized patients and those afflicted with cystic fibrosis. P. aeruginosa communicates intercellularly via a system of small ... -
Mechanistic analysis of a synthetic inhibitor of the LasI quorum-sensing signal synthase
(2015-11)Pseudomonas aeruginosa is an opportunistic Gram-negative pathogen responsible for many human infections. LasI is an acyl-homoserine lactone synthase that produces a quorum-sensing (QS) signal that positively regulates ... -
MICRONOME AND KSHV INFECTION: IDENTIFICATION AND FUNCTIONAL CHARACTERIZATION OF CELLULAR MICRORNAS DURING VIRUS ENTRY
(East Carolina University, 2018-04-17)Kaposi's sarcoma-associated herpesvirus (KSHV), is the most recently identified human herpesvirus and causes a variety of human malignancies. KSHV is etiologically associated with Kaposi's sarcoma (KS), primary effusion ... -
Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene, cblA, encoding the species-specific beta-lactamase.
(East Carolina University, 1994-08)The gene, cbl, encoding the species-specific, clavulanate-susceptible, endogenous cephalosporinase was cloned from Bacteroides uniforinis WAL-7088. The nucleotide sequence was determined, and the cbl structural gene was ... -
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 ... -
