Characterization of the Primary Starch Utilization Operon in the Obligate Anaerobe Bacteroides fragilis: Regulation by Carbon Source and Oxygen
(East Carolina University, 2006-07)The opportunistic pathogen Bacteroides fragilis is a commensal organism in the large intestine, where it utilizes both dietary and host-derived polysaccharides as a source of carbon and energy. In this study, a four-gene ... -
Characterization of the Vaccinia Virus A35R Protein and Its Role in Virulence
(East Carolina University, 2006-01)The vaccinia virus A35R gene is highly conserved among poxviruses and encodes a previously uncharacterized hydrophobic acidic protein. Western blotting with anti-A35R peptide antibodies indicated that the protein is ... -
Cloning and characterization of a conjugated bile acid hydrolase gene from Clostridium perfringens.
(East Carolina University, 1995-07)The gene encoding a conjugated bile acid hydrolase (CBAH) from Clostridium perfringens 13 has been cloned and expressed in Escherichia coli, and its nucleotide sequence has been determined. Nucleotide and predicted amino ... -
Cloning and characterization of the endogenous cephalosporinase gene, cepA, from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases.
(East Carolina University, 1993-11)Bacteroides frgiglis CS30 is a clinical isolate resistant to high concentrations of benzylpenicillin and cephaloridine but not to cephamycin or penem antibiotics. beta-Lactam resistance is mediated by a chromosomally encoded ... -
Cloning and Characterization of the Pseudomonas aeruginosa zwf Gene Encoding Glucose-6-Phosphate Dehydrogenase, an Enzyme Important in Resistance to Methyl Viologen (Paraquat)
(East Carolina University, 1998-04)In this study, we cloned the Pseudomonas aeruginosa zwf gene, encoding glucose-6-phosphate dehydrogenase (G6PDH), an enzyme that catalyzes the NAD1- or NADP1-dependent conversion of glucose-6-phosphate to 6-phosphogluconate. ... -
Co-targeting of Bcl-2 and mTOR pathway triggers synergistic apoptosis in BH3 mimetics resistant acute lymphoblastic leukemia
(2015-10)Several chemo-resistance mechanisms including the Bcl-2 protein family overexpression and constitutive activation of the PI3K/Akt/mTOR signaling have been documented in acute lymphoblastic leukemia (ALL), encouraging ... -
A combination of temsirolimus, an allosteric mTOR inhibitor, with clofarabine as a new therapeutic option for patients with acute myeloid leukemia
(2012-12)Signaling through the phosphatidylinositol 3-kinase (PI3K) pathway and its downstream effectors, Akt and mechanistic target of rapamycin (mTOR), is aberrantly activated in acute myeloid leukemia (AML) patients, where it ... -
Computational Modeling of PI3K/AKT and MAPK Signaling Pathways in Melanoma Cancer
(2016-03)Background Malignant melanoma is an aggressive tumor of the skin and seems to be resistant to current therapeutic approaches. Melanocytic transformation is thought to occur by sequential accumulation of genetic and ... -
Cooperative Effects of Akt-1 and Raf-1 on the Induction of Cellular Senescence in Doxorubicin or Tamoxifen Treated Breast Cancer Cells
(2011-08)Escape from cellular senescence induction is a potent mechanism for chemoresistance. Cellular senescence can be induced in breast cancer cell lines by the removal of estrogen signaling with tamoxifen or by the accumulation ... -
Crc Is Involved in Catabolite Repression Control of the bkd Operons of Pseudomonas putida and Pseudomonas aeruginosa
(East Carolina University, 2000-02)Crc (catabolite repression control) protein of Pseudomonas aeruginosa has shown to be involved in carbon regulation of several pathways. In this study, the role of Crc in catabolite repression control has been studied in ... -
The cyclic-di-GMP signaling pathway in the Lyme disease spirochete,
(2014-05)In nature, the Lyme disease spirochete Borrelia burgdorferi cycles between the unrelated environments of the Ixodes tick vector and mammalian host. In order to survive transmission between hosts, B. burgdorferi must be ... -
CYTOKINE-BASED FUSION PROTEINS FOR TREATMENT OF MULTIPLE SCLEROSIS
(2014-12-30)The present invention provides fusion proteins including an autoimmune antigen, an allergen antigen or an alloantigen, and an anti-inflammatory cytokine. Compositions and meth ods including the fusion proteins are also provided. -
Cytokine-Neuroantigen Fusion Proteins as a New Class of Tolerogenic, Therapeutic Vaccines for Treatment of Inflammatory Demyelinating Disease in Rodent Models of Multiple Sclerosis
(2012-08)Myelin-specific induction of tolerance represents a promising means to modify the course of autoimmune inflammatory demyelinating diseases such as multiple sclerosis (MS). Our laboratory has focused on a novel preclinical ... -
Cytokines and neuroantigens for treatment of immune disorders
(2017-05-10)The present invention provides methods of regulating an immunological disorder comprising administering to a subject an effective amount of (i) an autoimmune antigen in conjunction with (ii) an anti-inflammatory cytokine. ...
