Exceptions in protein superfamilies involved in exocytosis: Computational and biochemical studies
(ProQuest Dissertations & Theses, 2003)Life is uncertain: Eat desert first. (inscription on a bakery ).;Regulated exocytosis occurs upon stimulation with external stimulus, after which the membrane of a secretory vesicle fuses with the plasma membrane and the ... -
Experimental cerebral malaria induces cerebral vascular dysfunction and cognitive impairment via endothelin a receptor signaling
(ProQuest Dissertations & Theses, 2015)Cerebral malaria (CM) is the deadliest complication of Plasmodium falciparum (P. falciparum) infection. Despite extensive research, 20% of CM patients die, and of those that survive one in every four develop long-term ... -
Exploiting nature's glycan-transfer enzymes to investigate glycan function
(ProQuest Dissertations & Theses, 2014)Glycans are an important class of biological macromolecules that have diverse roles within the cell and on the cell surface. They are involved in immunological functions, cancer biology and stem cell biology to name a few ... -
Exploration of culture conditions that support the growth of human oligodendrocyte progenitors and examination of neuronal expression of a unique G-protein, Galphaz
(ProQuest Dissertations & Theses, 2000)The work presented in this thesis addresses two questions relevant to central nervous system function. The first explores culture conditions that could lead to the expansion in vitro of human oligodendrocyte (OL) precursor ... -
Exploring the PI3Kβ-Rab5 Interface
(ProQuest Dissertations & Theses Global, 2018)Class I Phosphoinositide 3-kinases (PI3Ks) are lipid kinases that regulate cell motility, growth, and survival. Class IA PI3Ks are obligate heterodimers that contain a regulatory subunit (p85α/β, p55α/γ, or p50α) and a ... -
Exploring the role of cholesterol in the Semliki Forest virus life cycle
(ProQuest Dissertations & Theses, 1995)This thesis focuses on the role of cholesterol in the life cycle of the enveloped alphavirus, Semliki Forest virus (SFV). SFV infects cells via a membrane fusion reaction triggered by low pH. For fusion to occur, cholesterol ... -
Exploring the role of gap junction-associated proteins in electrical synaptic transmission and its regulation
(ProQuest Dissertations & Theses, 2010)Plasticity of chemical synaptic transmission has been extensively investigated; on the other hand little is known about the plastic properties of gap junction-mediated electrical synapses. Since the finding that electrical ... -
Exploring the role(s) of oncogenic microRNAs in hepatocellular carcinoma
(ProQuest Dissertations & Theses, 2009)Small non-coding RNA known as microRNA (miRNAs) were considered to be superfluous genomic material for years. Recently, miRNAs have been shown to have regulatory roles in important cellular functions involved in carcinogenesis. ... -
Exploring the roles of ATP and hPrp5 in the 1(st) ATP-dependent step of spliceosome assembly
(ProQuest Dissertations & Theses, 2003)Conserved sequences within pre-mRNA are crucial for correct splicing of the message. One of these is the branch site, specifically the branch nucleotide (A), which participates in the transesterification reactions. The ... -
Expression and characterization of the sugar transporter, Glut 5 in microglial cells of the human and rat brain
(ProQuest Dissertations & Theses, 1999)All mammalian cells utilize and metabolize glucose for energy production. Glucose is transported into the cell by members of the family of facilitative glucose transporters, Glut 1-6. Each glucose transporter is cell and ... -
Expression and function of hematopoietic cytokines in developing brain
(ProQuest Dissertations & Theses, 1997)The ontogeny of the nervous system, like that of the immune system, is regulated in part by soluble peptides known as growth factors. In this study, we have investigated the role of hematopoietic cytokines, which include ... -
Expression and Subcellular Localization of the Kaposi's Sarcoma-Associated Herpesvirus K15P Protein during Latency and Lytic Reactivation in Primary Effusion Lymphoma Cells
(ProQuest Dissertations & Theses, 2018)Kaposi's Sarcoma Associated Herpesvirus (KSHV) is responsible for Primary Effusion Lymphoma (PEL), Multicentric Castleman Disease and Kaposi's Sarcoma, a multifocal angioproliferative neoplasm of endothelial cells. These ... -
EXPRESSION OF A PROKARYOTIC GENE IN SACCHAROMYCES CEREVISIAE (CHLORAMPHENICOL)
(ProQuest Dissertations & Theses, 1984)The antibiotic chloramphenicol (CM) inhibits the peptidyl transferase reaction of bacterial, mitochondrial and chloroplast ribosomes. Resistance to CM can be mediated by several different mechanisms; among these in the ... -
Expression of actin in Escherichia coli, its preparation in a soluble form, and its functional characterization
(ProQuest Dissertations & Theses, 1990)Bacterial strains were constructed for the expression of wild type and mutant Dictyostelium actin, and were shown to accumulate the appropriately sized actin species. These strains also accumulated a truncated 29 kDa actin ... -
Expression of H1 histone genes during mouse erythroleukemia cell differentiation
(ProQuest Dissertations & Theses, 1994)The mammalian H1 histones consist of multiple somatic H1s, a testis specific H1t, and the replacement linker histone H1{dollar}\sp0.{dollar} Increased H1{dollar}\sp0{dollar} levels are found predominantly in terminally ... -
Expression of var genes using novel integration methods in Plasmodium falciparum
(ProQuest Dissertations & Theses, 2010)Infection with Plasmodium falciparum can result in cerebral and placental malaria. PfEMP1 surface antigens are in large part responsible for this, and are encoded by a ∼60 member var gene family. The var family can be ... -
