Deficiency of a Sinorhizobium meliloti bacA Mutant in Alfalfa Symbiosis Correlates with Alteration of the Cell Envelope
(East Carolina University, 2002-10)The BacA protein is essential for the long-term survival of Sinorhizobium meliloti and Brucella abortus within acidic compartments in plant and animal cells, respectively. Since both the S. meliloti and B. abortus bacA ... -
DELINEATING THE MECHANISM OF AGGREGATE OR BIOFILM FORMATION IN THE LYME DISEASE SPIROCHETE BORRELIA BURGDORFERI
(East Carolina University, 2021-07-14)Borrelia burgdorferi, the spirochete causing Lyme disease, is transmitted to a vertebrate host by the bite of an infected Ixodes scapularis tick. The spirochete develops antibiotic resistance in humans likely due to the ... -
DELINEATING THE ROLE OF SOLUBLE CD25 AS AN IMMUNOREGULATORY MOLECULE THAT PROMOTES A LOW-ZONE IL-2 SIGNALING ENVIRONMENT FAVORABLE FOR THE SELECTION OF CD25HIGH FOXP3HIGH T CELLS
(East Carolina University, 2021-07-22)Autoimmune diseases develop due to the breakdown of tolerogenic mechanisms that normally maintain immune homeostasis. CD4+ CD25+ FOXP3+ regulatory T cells (Tregs) are critical in the maintenance of tolerance and the ... -
Development of small-molecule inhibitors of the initiating proteases, C1r and C1s, of the classical complement pathway
(East Carolina University, 2019-12-12)Complement is a proteolytic cascade that upon activation plays a key effector role in the innate immune system and acts to prime the adaptive immune response. During normal homeostatic events, complement is tightly regulated ... -
Differential regulation of the attachment of KSHV infected human B cells to ECM by KSHV encoded gB and cellular alpha-V integrins
(East Carolina University, 2008-07)Kaposi’s sarcoma-associated herpesvirus (KSHV) has two modes replication: latent and lytic replication. Reactivation from latency is dictated, in part, by the cell cycle. Herein, we have attempted to delineate the importance ... -
Direct Inhibition of RNAse T2 Expression by the HTLV-1 Viral Protein Tax
(2011-08)Adult T-cell leukemia (ATL) is one of the primary diseases caused by Human T-cell Leukemia Virus type 1 (HTLV-1) infection. The virally-encoded Tax protein is believed to initiate early events in the development of this ... -
Effect of in vitro transcription on cruciform stability.
(East Carolina University, 1990-05-11)We have investigated the effect of in vitro transcription on cruciform stability. Replicative form DNA of 4X174 strain ins6240, containing a 48 bp synthetic palindrome in the J-F intercistronic region, was supercoiled in ... -
Effects of Ectopic Expression of NGAL on Doxorubicin Sensitivity
(2012-10)Neutrophil gelatinase-associated lipocalin (NGAL, a.k.a Lnc2) is a member of the lipocalin family which has diverse roles including stabilizing matrix metalloproteinase-9 from auto-degradation and as siderocalins which are ... -
Effects of palindromes on in vivo DNA replication and mutagenesis in bacteriophage phi X174 RF DNA.
(East Carolina University, 1988-11-25)Bacteriophage IX174 mutants with insertions of palindromic DNA sequences are rapidly outgrown by competing wild-type phage (Muller & Turnage, J. Mol. Biol. 189: 285). The basis for this defect was investigated and found ... -
The Emerging Role of the Phosphatidylinositol 3-Kinase/ Akt/Mammalian Target of Rapamycin Signaling Network in Cancer Stem Cell Biology
(2010-08)The cancer stem cell theory entails the existence of a hierarchically organized, rare population of cells which are responsible for tumor initiation, self-renewal/maintenance, and mutation accumulation. The cancer stem ... -
Emerging targeted therapies for melanoma treatment (Review)
(2014-08)Cutaneous melanoma is an aggressive cancer with a poor prognosis for patients with advanced disease. The identification of several key molecular pathways implicated in the pathogenesis of melanoma has led to the development ... -
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 ... -
Enhanced Avidity Maturation of Antibody to Human Immunodeficiency Virus Envelope: DNA Vaccination with gp120-C3d Fusion Proteins
(East Carolina University, 2001-06-10)DNA vaccination can elicit both humoral and cellular immune responses and can confer protection against several pathogens. However, DNA vaccines expressing the envelope (Env) protein of human immunodeficiency virus (HIV) ... -
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 ... -
Essential Role of the Iron-Regulated Outer Membrane Receptor FauA in Alcaligin Siderophore-Mediated Iron Uptake in Bordetella Species
(East Carolina University, 1999-10)Phenotypic analysis using heterologous host systems localized putative Bordetella pertussis ferric alcaligin transport genes and Fur-binding sequences to a 3.8-kb genetic region downstream from the alcR regulator gene. ... -
Experimental autoimmune encephalomyelitis as a model of Multiple Sclerosis : pathogenesis of atypical disease and tolerance induction in chronic progressive disease
(East Carolina University, 2015)Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS) of putative autoimmune origin characterized by focal inflammatory lesions together with demyelinating plaques in the ...
