Biochemical And Cellular Mechanisms For The Antineoplastic Properties Of Sulindac, Jason Derek Whitt
Biochemical And Cellular Mechanisms For The Antineoplastic Properties Of Sulindac, Jason Derek Whitt
All ETDs from UAB
ABSTRACT The nonsteroidal anti-inflammatory drug (NSAID) sulindac has displayed the ability to inhibit the proliferation of colorectal cancer (CRC) cells and to increase the sensitivity of multidrug resistant (MDR) cancer cells to a wide variety of chemotherapeutic agents. The antineoplastic activity of sulindac has been attributed to inhibition of the prostaglandin producing enzyme COX-2, but the exact mechanism remains elusive and the inhibition of prostaglandin synthesis can result in gastrointestinal, hepatic, and cardiovascular toxicities. Enzymatic, cellular, and imaging assays were used to identify mechanisms that could contribute to the antiproliferative and apoptotic activity of sulindac. Screening of more than 500 …
Regulation And Function Of Interleukin-21-Producing T Cells And Immune-Mediated Control Of Hiv-1 Infection, Latonya Denise Williams
Regulation And Function Of Interleukin-21-Producing T Cells And Immune-Mediated Control Of Hiv-1 Infection, Latonya Denise Williams
All ETDs from UAB
CD8 T cells play a critical role in controlling intracellular pathogens, particularly viruses. However, during persistent viral infections, such as human immunodeficiency virus-1 (HIV-1) infection, virus-specific CD8 T cells become increasingly impaired by poorly understood mechanisms. Massive CD4 T cell depletion is a hallmark of HIV-1 infection and is associated with CD8 T cell dysfunction and ineffective viral containment. CD4 T cells provide critical helper signals to CD8 T cells, especially during uncontrolled viral infections. Mouse models of chronic viral infection implicate interleukin-21 (IL-21), produced primarily by CD4 T cells, as a vital factor necessary for the maintenance of fully …

Transcriptional Regulation Of Gfap, Sujeong Yeo
All ETDs from UAB
Glial fibrillary acidic protein (GFAP) is an astrocytic intermediate filament protein whose levels are increased in response to CNS injuries. Aim one of my thesis is to find the regulatory elements of the GFAP promoter responsible for its expression properties using a transgenic approach, since previous studies showed inconsistent results between in vitro and in vivo approaches. Two contiguous DNA segments previously implicated in transcriptional control of the GFAP gene, the B region (bp -1612 to -1489), and the C1.1 and C1.2 regions (bp -1488 to -1399), were analyzed. Block mutation of each of 4 contiguous sequences together spanning the …

Utilization And Effectiveness Of Osteoporosis Medications Among Medicare Beneficiaries, Huifeng Yun
All ETDs from UAB
This dissertation contains three papers evaluating the utilization and effectiveness of osteoporosis medications using data on a 5% sample of Medicare beneficiaries in 2006-2009. The first paper assessed the completeness of Medicare Part D data on generic alendronate. The second paper sought to identify anti-osteoporosis medication utilization patterns and factors associated with medication discontinuation. The third paper examined the comparative effectiveness of osteoporosis medications for risk of fractures and mortality, with a focus on the recently introduced infusion and injection medications. In the first study, we identified beneficiaries highly adherent with branded alendronate during 1/1/06-2/6/07 ("2007 cohort") and highly adherent …
Serotonin Signaling In Angiogenesis, Ali Zamani
Serotonin Signaling In Angiogenesis, Ali Zamani
All ETDs from UAB
Serotonin (5-hydroxytryptamine, 5-HT) is a well-known "happy" neurotransmitter. Selective serotonin reuptake inhibitors (SSRIs) are the most prescribed class of antidepressant medications to raise the serotonin level in the brain. However, the majority of serotonin in the human body is present outside of the brain and stored in platelets in blood circulation. Blood coagulation is a common feature of malignant solid tumors and leads to significant serotonin release from activated platelets into tumor environment. Due to the unique feature of platelet in lacking nucleus, the impact of platelet and serotonin on cancer progression has been overlooked by studies focusing on cancer …
Fcrl5 Exerts Binary And Compartment-Specific Influence On Innate-Like B Cell Receptor Signaling, Zilu Zhu
Fcrl5 Exerts Binary And Compartment-Specific Influence On Innate-Like B Cell Receptor Signaling, Zilu Zhu
All ETDs from UAB
Innate-like splenic marginal zone (MZ) and peritoneal cavity (PEC)-derived B1 B lymphocytes are the major contributors to primary humoral responses and play an important role in connecting innate and adaptive immunity, but are known to significantly differ in their B cell receptor (BCR) signaling characteristics. In mice, FCRL5 is discretely expressed by innate-like MZ and B1 B cells and is furthermore equipped with cytoplasmic ITAM-like and ITIM elements, suggesting diverse signaling potential for it. Our results showed that FCRL5 markedly inhibited BCR-mediated activation in MZ B cells, but not in PEC B1 B cells. To characterize its signaling function, a …
Evaluating The Efficacy Of Radiofrequency Amplitude-Modulated Electromagnetic Fields As A Novel Treatment For Hepatocellular Carcinoma, Jacquelyn Winifred Zimmerman
Evaluating The Efficacy Of Radiofrequency Amplitude-Modulated Electromagnetic Fields As A Novel Treatment For Hepatocellular Carcinoma, Jacquelyn Winifred Zimmerman
All ETDs from UAB
Hepatocellular carcinoma (HCC) incidence in the US is dramatically increasing. Five-year survival has remained 3-5% for the past several decades, demonstrating urgent need for additional therapies. Intrabuccal administration of amplitude-modulated radiofrequency electromagnetic fields (RF EMF) is a novel, minimally invasive treatment modality. Clinical evidence demonstrates this treatment approach elicits therapeutic responses in cancer patients. In vitro we have described a phenotype in HCC cells following RF EMF exposure that included proliferative inhibition, modulation of gene expression, and disruption of the mitotic spindle. This phenotype was specific for HCC cells exposed to HCC-specific RF EMF. We have demonstrated similar efficacy in …
Regulation Of Clc-3 In Human Malignant Glioma, Vishnu Anand Cuddapah
Regulation Of Clc-3 In Human Malignant Glioma, Vishnu Anand Cuddapah
All ETDs from UAB
Malignant gliomas are the most common and deadly form of primary brain cancer afflicting adults. Current treatment regimens, including surgical debulking, radiotherapy, and chemotherapy, have limited efficacy, and median patient survival remains only 14 months. Therefore, novel therapies must target different aspects of glioma biology. Two of the most striking features of this cancer are the unusual ability of glioma cells to robustly proliferate and migrate in the brain, and recent evidence suggests that ClC-3, a voltage-gated Cl- channel/transporter is implicated in both of these processes. We hypothesize that ClC-3 may facilitate proliferation and migration by promoting hydrodynamic shape and …

Clinical Evaluation Of Treatment Of White Spot Lesions With Icon, Candace A. Cronan
All ETDs from UAB
Introduction: Despite an increased awareness by clinicians and their attempt to aid patients in the prevention of white spot lesions, enamel demineralization continues to be a problem associated with orthodontic treatment. Current treatment options for these unaesthetic scars on the teeth range from conservative options for remineralization such as the use of fluoride and CPP-ACP to more aggressive treatment involving loss of tooth structure with microabrasion or restorations. An innovative option for treatment has recently been introduced in the form of the infiltrant resin, Icon. Icon infiltration is a minimally invasive procedure performed by a dentist that is claimed to …
Adhesion Molecule Interactions Influence The Implementation Of Immune Responses To Infection, Maureen Ann Cox
Adhesion Molecule Interactions Influence The Implementation Of Immune Responses To Infection, Maureen Ann Cox
All ETDs from UAB
Interactions mediated by intercellular adhesion molecule-1 (ICAM-1) enhance both the antigenic and cytokine signals that CD8 T cells perceive, and these interactions have been suggested to be required for the formation of memory CD8 T cells. Following acute lymphocytic choriomeningitis virus (LCMV) infection of ICAM-1-/- mice, we observe elevated numbers of "effector-phenotype" (CD127lo KLRG-1hi IL-2-) virus-specific CD8 T cells well into the memory phase, while the development of memory-phenotype CD8 T cells (CD127hi KLRG-1lo IL-2 producing) is not impaired. The enhanced maintenance of effector-phenotype cells is due to ICAM-1 deficiency on non-T cell subsets, suggesting a role for ICAM-1 mediated …
Modulation Of Alpha-Synuclein Metabolism And Toxicity By Cathepsin D, Donna Marlana Crabtree
Modulation Of Alpha-Synuclein Metabolism And Toxicity By Cathepsin D, Donna Marlana Crabtree
All ETDs from UAB
Parkinson's disease (PD) is the most commonly occurring neurodegenerative movement disorder, and aberrant accumulation of the protein α-synuclein is thought to be a major contributing factor in disease development. Dysfunction of the autophagy lysosome pathway (ALP) has been implicated in PD pathogenesis. Our lab and others have shown that the lysosomal enzyme cathepsin D (CD) is an important regulator of α-synuclein degradation. The primary focus of this thesis is probing the structure/function dynamic that exists between α-synuclein and CD. We have found that lentiviral-mediated over expression of wild type CD (wtCD) leads to subtle alterations in the ALP in a …

Analysis Of Ergothioneine Production In Mycobacterium Tuberculosis, Loni Ann Guidry
Analysis Of Ergothioneine Production In Mycobacterium Tuberculosis, Loni Ann Guidry
All ETDs from UAB
Mycobacterium tuberculosis (Mtb), the etiological agent of tuberculosis, currently infects more than two billion people worldwide. Mtb is a highly adaptable pathogen, capable of modifying its metabolism in response to its environment. We previously showed that Mtb WhiB3 is a redox-responsive regulator of core intermediary metabolism and lipid anabolism through which it maintains redox homeostasis. In this work, through the use of metabolomic analysis and a novel radioactive thin layer chromatography assay, we discovered that WhiB3 regulates the production of the intracellular thiol ergothioneine (ergo) when using immunomodulatory lipid precursors as the major carbon source. Our results suggest that this …
A Yeast Model For High Throughput Screening Of Gene-Gene Interactions Relevant To Cftrδf508 Protein Biogenesis, Jingyu Guo
All ETDs from UAB
Much remains unknown about gene interaction in the context of human disease. In cystic fibrosis (CF) a single mutation of the cystic fibrosis transmembrane conductance regulator (CFTR-deltaF508) accounts for most disease. In cell models, CFTR-deltaF508 causes defective protein biogenesis and degradation rather than proper trafficking to the plasma membrane where CFTR normally functions in ion transport. Numerous genes function in the biogenesis of CFTR and influence the fate of CFTR-deltaF508 in cell models. However it is not known whether natural genetic variation in such genes contributes to disease severity in patients. Moreover, there is no easy way to predict how …

The Role Of Histone Methylation In The Medial Temporal Lobe During Long-Term Memory Formation, Swati Gupta
All ETDs from UAB
Several studies have established the importance of epigenetic regulation of gene transcription in the brain during memory consolidation. Epigenetic mechanisms involve modifying the DNA or the associated histone proteins to determine the transcriptional outcome of a gene. The work encompassed in this dissertation serves as an initial investigation for the role of histone lysine methylation mechanisms in regulating gene activation and suppression in the medial temporal lobe that includes entorhinal cortex (EC), hippocampus, and amygdala during memory consolidation. To this end, we found that di-methylation of histone H3 at lysine 9 (H3K9me2) which promotes gene suppression was specific to associative …

A Phenomenological Study Of Obesity And Its Impact On Functional Status, Life-Space Mobility, And Physical Activity In Southern African American Older Women, Pamela G. Bowen
All ETDs from UAB
The majority of work on health disparities has focused on public policy and identifying disparate conditions. Obesity is a significant public health problem that has reached epidemic proportions, considered the second leading cause of preventable death, encourages a sedentary lifestyle, and can lead to a higher prevalence of functional impairments. Moreover, obesity increases the risk that persons may develop one or more serious medical conditions, such as cardiovascular disease, hypertension, stroke, Type 2 diabetes, and osteoarthritis, especially among African Americans. In the United States, African American women are more likely to be classified as overweight or obese. In fact, approximately …
The Role Of Vpr-1 Msp Signaling In C. Elegans, Sung Min Han
The Role Of Vpr-1 Msp Signaling In C. Elegans, Sung Min Han
All ETDs from UAB
In C. elegans, the major sperm protein (MSP) is the most abundant protein in sperm and functions as an intracellular cytoskeleton protein and a secreted extracellular signal that induces oocyte maturation and sheath contraction. Evolutionarily, MSP domain-containing proteins originate from the VAPs (VAMP/synaptobrevin-associated proteins), which comprise a highly conserved protein family with an MSP domain at the N-terminus and a transmembrane domain at the C-terminus. I have been studying the signaling role of VAP MSP domains using the C. elegans model system. In collaboration with Hugo Bellen's lab at Baylor College of Medicine, we have shown that C. elegans, Drosophila, …

High-Risk Human Papillomavirus And Cervical Intraepithelial Neoplasia Among Foreign-Born Latinas At Colposcopy, Bertha Hidalgo
All ETDs from UAB
Although the literature is quite extensive with regard to the human papillomavirus (HPV) among many racial/ethnic populations, there continues to be a paucity of information regarding the prevalence of HPV types as well as of cervical intraepithelial neoplasia (CIN among Latinas, specifically foreign-born Latinas. Some studies have reported prevalence of HPV among Latinas, but very few have differentiated between US- and foreign-born Latinas. This nuance is essential to understanding the true effect contributed by each group to HPV and CIN incidence and prevalence rates. Therefore, this dissertation aimed to assess differences in the prevalence of high- and low-risk types and …

Mitochondrial Morphology And Function In Neuronal Cells Under Stress, Lonnie Schneider
All ETDs from UAB
Neurodegenerative disease encompasses a wide range of conditions and pathologies that can manifest at any age depending on the etiology. A major factor in both early onset and age-related neurodegeneration is mitochondrial dysfunction. To investigate how mitochondrial bioenergetics is affected by cellular stress, we used an in vitro culture system to examine mitochondrial function in response to oxidative stress. We also studied an in vivo model of neuronal ceroid lipofuscinosis to determine the impact of deficient autophagy-lysosomal activity on mitochondrial morphology, composition and function. In vitro we found that retinoic acid-induced differentiation of dopaminergic neuroblastoma SH-SY5Y cells exhibited increased mitochondrial …

Perceived stress may negatively affect job performance. Perceived stress is known to alter physiological responses, including cortisol response. Cortisol affects working memory and may explain how stress affects performance. Aeromedical crewmembers transport wounded soldiers in the austere aeromedical environment. The demands of the Aeromedical Evacuation (AE) may lead to stress and impact job performance. The AE training mission simulates real world operational missions and this setting was used to examine the effects of perceived stress on job performance among aeromedical crewmembers at different time points during the mission (Time 1- baseline, Time 2 - pre-flight, Time 3 - in-flight, Time …
Antiphagocytic Factors Of Mycoplasma Pulmonis, Brandon Michael Shaw
Antiphagocytic Factors Of Mycoplasma Pulmonis, Brandon Michael Shaw
All ETDs from UAB
Mycoplasma pulmonis is a murine respiratory pathogen and is used as a model for studying chronic mycoplasmal respiratory disease. This organism has been used by many in vivo and in vitro studies to gain a better understanding of host-pathogen interactions in chronic respiratory infection. Studies have shown that alveolar macrophages play an important role in the removal of this pathogen from the host. Given that M. pulmonis is able to produce a chronic disease state, this organism should produce antiphagocytic factors that aid in avoidance of killing by alveolar macrophages. The Vsa proteins are involved in the avoidance of killing …

Apolipoprotein E Mimetic Peptide Improves Hdl Functionality And Inhibits Atherosclerosis Progression In Mouse Models Of Atherosclerosis, Gaurav Nayyar
All ETDs from UAB
Despite major advances in diagnosis and treatment, coronary artery disease (CAD) is still the number one cause of morbidity and mortality in United States. An ideal treatment for lipid-mediated inflammatory disorders would not only reduce plasma cholesterol dramatically but also improve high density lipoproteins (HDL) function. Apolipoprotein E (apo E), a protein component of HDL and very low density lipoprotein (VLDL), is necessary for the receptor mediated hepatic uptake of apolipoprotein-B (apo B) containing remnant lipoproteins and also possesses strong anti-inflammatory properties. We hypothesized that a synthetic dual domain apo E mimetic peptide, Ac-hE18A-NH2 (a 28-residue peptide) containing receptor binding …
