The Phenotypic Expression Of Usp14 Deficiency Is Dependent Upon Genetic Background, Andrea Gail Marshall
The Phenotypic Expression Of Usp14 Deficiency Is Dependent Upon Genetic Background, Andrea Gail Marshall
All ETDs from UAB
The ubiquitin proteasome system (UPS) plays a critical role in regulating a diversity of cellular processes that are essential to neuronal function, such as synaptic transmission, axon guidance, and neurite outgrowth. Dysfunctions of the UPS are linked with many neurodegenerative disorders, including motor neuron diseases like spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS), although it is not known how UPS dysfunction contributes to disease pathology. The proteasome, an approximate 2.5 megadalton protein complex comprised of a 20S core particle and 19S regulatory particle, is the site of ubiquitin-mediated proteolysis in the cell. Recent studies have linked ubiquitin specific …
Cd5 Regulation Of T Helper Cell Differentiation And Cytokine Signaling, Donald J. Mcguire
Cd5 Regulation Of T Helper Cell Differentiation And Cytokine Signaling, Donald J. Mcguire
All ETDs from UAB
CD5 is expressed on T and B1a cells and is an important regulator of cell survival and activation. Engagement of CD5 promotes cell survival through the activation of the serine threonine kinase CK2. Mice with genetic abrogation of CD5 binding to CK2 (CD5∆CK2bd) exhibited reduced severity of experimental autoimmune encephalomyelitis that was associated with increased activation induced cell death. In addition to inhibiting cell death, CD5 activation of CK2 significantly enhances Th17 differentiation. Loss of CD5-CK2 signaling reduces the generation of Th17 cells despite an unexpected increase in pSTAT3 levels. The mechanisms of CD5's enhancement of Th17 differentiation have not …
Intrinsic And Extrinsic Factors Required For Cd4 T Memory Cell Formation And Function, Sarah B. Mollo
Intrinsic And Extrinsic Factors Required For Cd4 T Memory Cell Formation And Function, Sarah B. Mollo
All ETDs from UAB
CD4 T cells are central to the organization of the immune response through the secretion of cytokines that recruit and activate other immune cells. Following infection and pathogen control, the majority of the effector CD4 T cells undergo apoptosis, leaving a subset that persists and gives rise to the memory T cell pool. Upon encountering the same pathogen, memory CD4 T cells respond rapidly, providing enhanced protection from re-infection. What determines which effector CD4 T cells will survive is unclear; however, there are a number of factors both intrinsic to the cell as well as external signals from the environment …

Phenotypic Analysis Of B Cells In Hla*B44 Positive Patients That Exhibit Common Variable Immunodeficiency And Recurrent Sino-Pulmonary Infections, Eva Szymanska Mroczek
All ETDs from UAB
Depressed serum immunoglobulin levels and recurrent sinopulmonary infections mark Common Variable Immune Deficiency (CVID). Many family members of CVID patients also suffer Recurrent Sino-Pulmonary Infection (RESPI) but have normal serum immunoglobulins. We identified HLAB44 positive identical female twins who suffer sinopulmonary infections and are discordant for CVID and RESPI. Flow cytometry subsets showed equivalent numbers of immature B cells (BC) in both twins, but lower numbers of transitional and mature BC in the CVID twin. Presented is an in-depth comparison of V (D) J gene usage, hydrophobicity, length, DH reading frame, and amino acid usage between µ H chain repertoires …
Identification Of Claudin-1 As An Entry Factor In Dengue Infection And Development Of A High Throughput Screening Assay For Antivirals Against Dengue Virus, Pulin Che
All ETDs from UAB
Dengue virus (DENV) has become a huge public health concern around the world with no vaccine or antivirals available. More than one-third of the world's population is living in areas at risk of infection. To conquer the dengue disease, a better understanding of virus-host interactions and development of the appropriate therapeutic treatments are required. In this dissertation, we first broadly reviewed the factors involved in dengue viral entry and the role of tight junctions as a pathogen target. Second, we developed, optimized and validated a high throughput screening (HTS) assay for anti-dengue virus drug screening. Taking advantage of using live …
Structure-Function Analysis Of Tyrosyl-Dna Phosphodiesterase I, Evan Comeaux
Structure-Function Analysis Of Tyrosyl-Dna Phosphodiesterase I, Evan Comeaux
All ETDs from UAB
Tyrosyl-DNA phosphodiesterase I (Tdp1) functions to remove 3'phospho-DNA adducts, such as eukaryotic DNA Topoisomerase I (Top1) covalently bound to the DNA by a 3'phospho-tyrosyl bond. As member of the Phospholipase D superfamily Tdp1 contains two HxK(n)N motifs, each of which provide a catalytic histidine: one functioning as a nucleophile to bind the 3'phosphate and the other as a general acid/base to hydrolyze Tdp1's 3'phospho-histidyl bond. Mutation of the general acid/base catalytic histidine (Hisgab) to arginine has been implicated in the autosomal recessive neurodegenerative disease SCAN1. Further study of the yeast enzyme revealed that substitution of Hisgab in yeast Tdp1 to …
Understanding The Function And Regulation Of Eukaryotic Release Factor 1, Erf1, Sara Elisabeth Conard
Understanding The Function And Regulation Of Eukaryotic Release Factor 1, Erf1, Sara Elisabeth Conard
All ETDs from UAB
Translation termination is an essential eukaryotic process that facilitates the end of protein synthesis and mediates the release of the nascent peptide chain. Two release factors, eRF1 and eRF3, with the help of a ribosome recycling factor assist in this process. eRF1 and eRF3 form a stable complex through conserved regions in their C-terminal domains. The eRF1/eRF3 complex, along with GTP, is absolutely vital for efficient termination in vitro and in vivo. The role of eRF1 during translation termination is to recognize the stop codon located in the ribosome aminoacyl site, stimulate GTP hydrolysis of eRF3 and enable peptide release …
Tgf-Ss And Erg In Intervertebral Disc Development, Megan Karen Cox
Tgf-Ss And Erg In Intervertebral Disc Development, Megan Karen Cox
All ETDs from UAB
The intervertebral disc (IVD) is a fibrocartilaginous tissue that acts as a shock absorber between adjacent vertebrae in the spinal column. It is comprised of two parts, the inner jelly-like nucleus pulposus (NP) and the outer more fibrous annulus fibrosus (AF). Most IVD research has focused on the development of the NP, which is derived from condensations of the notochord involving sonic hedgehog (Shh) signaling. In contrast, very little is known about the molecular mechanisms underlying the specific development of the AF of the IVD. The AF is derived from the sclerotome, which is formed by the ventral half of …
Selection And Evolution Of Pneumococci In Response To Conjugate Vaccines, Christina M. Croney
Selection And Evolution Of Pneumococci In Response To Conjugate Vaccines, Christina M. Croney
All ETDs from UAB
Pneumococcal conjugate vaccines (PCVs) containing subsets of the >90 capsular polysaccharide antigens have been successful as a means of decreasing invasive and non-invasive pneumococcal disease worldwide. However, this success is limited to the specif-ic capsular serotypes against which PCVs are formulated and studies have reported the increase of nonvaccine serotypes. The 13-valent pneumococcal conjugate vaccine (PCV13) was introduced in the United States in 2010 for the prevention of invasive pneumococcal disease (IPD) and otitis media and was released without efficacy data. In this study we set out to 1) determine potential efficacy for invasive and noninvasive pneumococcal disease and 2) …
An Investigation Of Trem-Like Transcript 2 Expression, Kimberly Anne Thomas
An Investigation Of Trem-Like Transcript 2 Expression, Kimberly Anne Thomas
All ETDs from UAB
Acute inflammation is a necessary component for the clearance of pathogens. Cells at the site of infection utilize highly conserved receptors to both recognize microbes and induce the production of pro-inflammatory stimuli. These stimuli set off a chain reaction that includes localized vasodilation, leukocyte infiltration, and tissue destruction, collectively known as inflammation. Tightly controlled, this process is protective, and can compartmentalize the damage to a defined area, but when dysregulated can be catastrophic, inducing chronic inflammation and even death. Families of innate receptors can modulate inflammatory processes, and in doing so, increase or decrease their severity, as well as tailor …
Neutropenia And Progenitor Cell Mobilization In Ap3-B1 Mutant Pearl Mice, Matthew Vallejo
Neutropenia And Progenitor Cell Mobilization In Ap3-B1 Mutant Pearl Mice, Matthew Vallejo
All ETDs from UAB
Mutations in the AP3-ß1 gene are known to cause Hermansky-Pudlak syndrome type 2 (HPS2) in humans and canine cyclic hematopoiesis (CH) in gray collie dogs. HPS2 patients have severe congenital neutropenia (SCN), and dogs have cyclic neutropenia (CN). The mechanism behind neutropenia is uncertain. Pearl mice have an AP3-ß1 mutation, but whether they actually have neutropenia has not yet been evaluated. This dissertation presents a discussion of the evaluation of neutropenia in pearl mice, hematopoietic progenitor cell mobilization defect in pearl mice and finally an evaluation of methods of dog-to-mouse xenotransplantation to establish a xenotransplant model of the dog hematopoietic …
Intrinsic Properties Of Rna Polymerase I And Trans-Acting Factors Control Transcription Elongation Efficiency, Olga V. Viktorovskaya
Intrinsic Properties Of Rna Polymerase I And Trans-Acting Factors Control Transcription Elongation Efficiency, Olga V. Viktorovskaya
All ETDs from UAB
Transcription of ribosomal (r) DNA by RNA polymerase I (Pol I) is the initial step of ribosome synthesis. Pol I transcription is unique in its high rate of initiation, specific organization within the nucleolus and tight connection to cell growth and proliferation. Moreover, transcription elongation by Pol I is functionally coupled with rRNA processing and assembly of the ribosomes. Regulatory insights into transcription elongation by Pol I and its interface with rRNA processing are limited, despite decades of research. To fulfill that gap, we asked several important questions: Do the obvious functional divergences between Pol I and other eukaryotic polymerases …

Glioma-Vasculature Interactions, Stacey Watkins
All ETDs from UAB
Malignant gliomas are highly invasive brain tumors, which lack effective treatment options. To date, the standard therapy includes surgical debulking followed by chemotherapy and radiation. Despite efforts to eradicate the disease, the median patient survival time is only 14 months. In an attempt to discover novel therapies, research has focused on understanding the heterogeneous biological mechanisms employed by these cells. Uniquely, they do not metastasize through the vasculature or lymphatics like other solid cancers but alternatively, glioma cells utilize the abluminal surface of the vasculature to guide invasion and migration throughout the brain. The intimate association between glioma cells and …
Hur Regulation In Central Nervous System Disorders, Crystal G. Wheeler
Hur Regulation In Central Nervous System Disorders, Crystal G. Wheeler
All ETDs from UAB
In inflammatory diseases of the central nervous system (CNS), astrocytes play a major role in the systemic response to disease by either enhancing or limiting the inflammatory response through secretion of growth factors or cytokines. HuR RNA binding protein regulates many genes involved in inflammation. Inflammatory diseases such as brain tumors, Amylotrophic Lateral Sclerosis (ALS), and Multiple Sclerosis (MS), have been linked to HuR, by our laboratory and others. To determine whether astrocytic overexpression of HuR would regulate inflammation in diseases of the CNS, we designed a transgenic mouse in which the HuR gene is overexpressed. In the first study, …

All ETDs from UAB
Gyrase introduces negative supercoils into bacterial DNA. In balance with topoisomerase I, it contributes to the maintenance of constant negative DNA supercoiling. It was shown that in Escherichia coli negative supercoil density of pBR322 plasmid is higher than in Salmonella typhimurium. One of the possible explanations of this phenomenon is a difference of DNA gyrase activity between E. coli and S. typhimurium. We developed in vitro assay of gyrase activity which has shown that DNA gyrases of E. coli and S. typhimurium have the same supercoiling end point, but E. coli gyrase works slightly faster than the S. typhimurium enzyme. …

Role Of Gsk3 In The Immunopathogenesis Of Eae, Amber Rowse
All ETDs from UAB
Lithium, a glycogen synthase kinase 3 (GSK3) inhibitor, ameliorates experimental autoimmune encephalomyelitis (EAE), the murine model of multiple sclerosis (MS) in different mouse models. However, the mechanism of lithium's attenuation of EAE and the role of GSK3 in these processes are currently unknown. IFN-g producing Th1 cells and IL-17-producing Th17 cells are both effector cells in MS and in EAE models. However, relapsing remitting MS patients segregate into Th1 or Th17 serum cytokine signatures and each is differentially responsive to IFN-ß therapy, a first line therapy for MS. Studies in this dissertation revealed a differential effect of lithium on Th1 …

Atherosclerosis is a chronic inflammatory disease of the vessel wall and underlying cause of most cardiovascular disease. Much is understood about the nature of atherosclerosis development, including contributions from leukocytes that drive the disease process forward. The general process by which leukocytes are trafficked to sites of atherosclerosis development, and sites of inflammation in general, is understood and relies upon endothelial expressed protein adhesion molecules which serve as ligands for cognate leukocyte receptors. While these adhesion molecules share the post-translation modification of N-glycosylation, relatively little is known as to what functional role these modification plays in: i) interactions of leukocytes …

Epigenetic Markers In The Developing Postnatal Brain, Rebecca Kaye Simmons
All ETDs from UAB
Epigenetic mechanisms provide a critical and plausible mechanism by which genes and the environment can interact and have been implicated in a number of diseases and disorders. In order to better understand how epigenetic mechanisms go awry in a diseased brain we must first understand how epigenetic mechanisms unfold during normal development. The present body of work begins to examine the role of DNA methylation in normal development and how it may contribute to a rodent model of emotion dysfunction. Using a variety of techniques, we evaluated the transcript, protein and functional output levels of DNA methyltransferase1, -3a, and -3b …
Modulation Of Intrinsic Activity In Sensory Cortex Facilitates Task Performance, Aburahman Elkhetali
Modulation Of Intrinsic Activity In Sensory Cortex Facilitates Task Performance, Aburahman Elkhetali
All ETDs from UAB
Due to the changing demands of the environment and our behavioral intentions the brain has to adapt in order to produce task appropriate responses. Part of the challenge is the large amount of sensory information received by the brain. Depending on individu-al goals, the brain must select and react to task appropriate stimuli while ignoring other irrelevant sensory input. Since behavioral intentions are dynamic, this requires the re-sponses within the brain to also be dynamic. Cognitive control, exerted by higher centers on sensory cortex allow for selection of task relevant stimuli. In this study we find that intrinsic, non-stimulus driven …
Regulation Of Capsule By Cpsa And Global Regulatory Networks In Streptococcus Pneumoniae Type 2, Kanupriya Gupta
Regulation Of Capsule By Cpsa And Global Regulatory Networks In Streptococcus Pneumoniae Type 2, Kanupriya Gupta
All ETDs from UAB
Streptococcus pneumoniae is a major human pathogen that can reside asymptomatically in the nasopharynx before causing invasive disease by entering systemic sites. This involves regulation of colonization and virulence factors including capsule. cps2A, the first gene of the capsule (cps) locus has been proposed to regulate capsule, however its exact role and mechanism is not well understood. A complete deletion of cps2A resulted in enhanced capsule levels, with no alteration in the transcription levels of cps genes. Complementation of Cps2A restored wild type levels of capsule. Expression of the C-terminal tail alone was able to partially complement the deletion strain, …

Potential Roles Of The Immunostimulatory Signals Il-15 And Mica In Oncolytic Hsv-1 Therapy For Malignant Glioma, David Curtis Gaston
All ETDs from UAB
Malignant gliomas are the most frequently diagnosed and the most fatal primary brain tumors. Innovative therapeutic approaches are necessary to combat these devastating cancers, and oncolytic herpes simplex virus type-1 (oHSV) deleted of the γ134.5 neurovirulence gene is a promising adjunctive therapy. The primary mechanism of tumor clearance by oHSV is lytic replication specifically within malignant cells. oHSV also stimulates tumor infiltration of cytotoxic immune effector cells that can participate in tumor clearance. However, cytotoxic immune cells target oHSV as well as tumor, which may limit therapeutic efficacy. Further knowledge regarding the nature of these interactions and how the interactions …

Congenital human cytomegalovirus (HCMV) infection is a complex cause of central nervous system (CNS) disease. Infection with HCMV during pregnancy results in virus transmission across the placenta and infection of the fetus. With a seroconversion rate in pregnant women between 1% and 4%, HCMV is the most frequently transmitted virus from mother to developing child. Each year between 2,000 and 4,000 infants will suffer from long-term neurologic deficits as a result of congenital infection. The well documented CNS sequelae resulting from congenital HCMV infection have described a wide range of damage without a specific set of pathologic markers for disease. …

O-Linked Beta-N-Acetylglucosamine (O-Glcnac) And The Mitochondrion, Christopher Calderon
All ETDs from UAB
O-linked beta-N-acetylglucosamine (O-GlcNAc) is a dynamic and ubiquitous posttranslational modification of serine and threonine residues on nuclear and cytoplasmic proteins. O-GlcNAc has emerged as an important regulator of cellular processes such as cell signaling, transcription, translation, apoptosis, and cell cycle regulation, among others. O-GlcNAc is thought to be a contributor to pathologies such as hyperglycemia and insulin resistance. O-GlcNAc has been viewed as an indicator of cellular energy levels and is associated with diabetic complications under nutrient excess. Other studies have shown that a variety of stress stimuli increase the levels of protein O-GlcNAc in mammalian cells, and this increase …
The Molecular Mechanisms Underlying Cardiac Hypertrophy Due To Volume Overload., Justin Andrew Barnes
The Molecular Mechanisms Underlying Cardiac Hypertrophy Due To Volume Overload., Justin Andrew Barnes
All ETDs from UAB
Mitral regurgitation (MR) is a common form of heart disease, but there are no approved medical therapies for MR or other cardiovascular conditions associated with hemodynamic volume overload (VO) and eccentric remodeling. We have previously shown that a standard heart failure treatment, ß-adrenergic system blockade (ß-RB), improves function in animal models of VO and in MR patients without attenuating the adverse eccentric hypertrophy that occurs in conjunction with VO. This paradox highlights how poorly we understand eccentric remodeling of the heart, and a better understanding of the molecular mechanisms at work in VO must be obtained before we can develop …

Adapter Based Strategies For Adenovirus Vector Retargeting To T Lymphocytes, Matthew S. Beatty
All ETDs from UAB
Adenoviruses are the most commonly used gene therapy vector for cancer therapy clinical trials. While adenovirus has shown a great track record in a variety of cancer therapeutics it has not progressed as a vector system for the modification of T lymphocytes. One of the major roadblocks towards utilizing adenovirus for T cell therapy is the lack of coxsackie virus and adenovirus receptor on the cell surface of T cell lineages. Exploitation of alternative receptors has allowed adenovirus vectors to be utilized in a variety of cell types that native adenovirus type 5 cannot infect. Thus, retargeting adenovirus to an …

Astrocytes are the most numerous cells in the brain and play a critical role in maintaining homeostatic extracellular potassium ([K+]e). This process is mediated, in part, by a glial-specific, inwardly rectifying potassium channel, Kir4.1. Pharmacological inhibition, knock down, or complete knock out of this channel results in astrocytes with increased membrane resistance, depolarized resting membrane potential, and altered extracellular potassium dynamics. Subsequent to the dysregulation of [K+]e, Kir4.1 knockout (KO) animals suffer from ataxia, seizures, and early postnatal death. Interestingly, Kir4.1 has long been characterized as a seizure susceptibility gene. The importance of Kir4.1 is further underscored by recent studies …

Hedgehog (Hh) signaling is required for many developmental processes, and causes several diseases and cancers. Described in chapter one below, vertebrate Hh sig-naling is dependent on the primary cilium (PC), a small organelle that extends from the surface of most mammalian cell types. A better understanding of how the PC modulates Hh signaling is important, as defects in the structure or function of PC result in severe human disorders termed the ciliopathies. For example, patients with Meckel-Gruber Syndrome have extra digits and neural tube defects, which are Hh both related pheno-types. In chapter two we sought to further understand the …

Phospho-Erk And Amyloid Beta: Targets Of Estrogen In The Brain, Thomas Reed Peavy
All ETDs from UAB
Estrogen replacement therapy (ERT) has been shown to improve memory function in menopausal women, but increases hormone sensitive cancers, prompting a more targeted investigation of estrogen's action in learning and memory to develop more targeted therapeutics. Estrogen improves performance on the novel object recognition task by increasing phosphorylation of extracellular signal-regulated kinase (pERK) within minutes in the hippocampus. Dr. Lori McMahon's lab showed that the improvement in novel object recognition can be seen 24 hours after subcutaneous injection of proestrous levels of estrogen (referred to as E24). Whether a corresponding increase in pERK occurs at the E24 time point had …
The Origin, Regulation, And Function Of Tbet In Effector Cd4 T Cells During Chronic Autoimmune Disease, Wen-I Yeh
All ETDs from UAB
Multiple Sclerosis (MS) is an autoimmune disease resulting from aberrant immune cells causing demyelination. We utilize the well-studied mouse model, experimental autoimmune encephalomyelitis (EAE), to decipher the underlying pathogenesis of MS. Effector CD4 T-cells play a critical role during EAE because the disease is induced by adoptively transferring myelin-specific CD4 T-cells into naïve mice. Classically, effector CD4 T-cells have been divided into distinct subsets based on their functional properties: Th1 cells produce IFNγ, Th2 cells secrete IL-4, IL-5, and IL-13, Th17 cells make IL-17A, IL-17F, IL-21, and IL-22, and regulatory T cells produce IL-10. Th1 cells were originally identified as …

Regulation Of Stim1 By O-Glcnacylation In Cardiomyocytes, Xiaoyuan Zhu-Mauldin
All ETDs from UAB
In non-excitable cells, STIM1 and Orai1 are the primary mediators of store-operated Ca2+ entry (SOCE); however little is known about their roles in cardiomyocyte Ca2+ handling. We have previously shown that acute increases in the levels of O-GlcNAcylation (the attachment of O-linked N- acetylglucosamine (O-GlcNAc) to target proteins) are cardioprotective through attenuating Ca2+-mediated injury and increased O-GlcNAcylation blunts SOCE in cardiomyocytes. Therefore, the goals here were to determine the regulation of STIM1 and STIM1-mediated SOCE by O-GlcNAcylation in cardiomyocytes. Immunohistochemical analysis demonstrated the co-localization of STIM1 with SERCA and RyR in adult cardiomyocytes. NRVMs were transfected with the eYFP-tagged STIM1 …
