Epigenetic Regulation Of Stem Cell Fate Determination And Tumorigenesis, Kushani Shah Jan 2018

Epigenetic Regulation Of Stem Cell Fate Determination And Tumorigenesis, Kushani Shah

All ETDs from UAB

It is unclear how H3K4 methylation, an epigenetic modification associated with gene activation, regulates stem cell fate determination and tumorigenesis. DPY30 is one of the core subunits of the SET1/MLL complex in mammals responsible for H3K4me. DPY30 enhances the H3K4me activity of the SET1/MLL complex. Here, I sought to define role of DPY30 and H3K4me3 in postnatal neurogenesis and hematopoietic malignancies. Using a conditional knockout model, I found that Dpy30 deficiency halts the development of postnatal hippocampus, the subventricular zone, and cerebellum. Deficiency in cerebellum is most likely the cause of uncoordinated ataxia-like movements in these mice. By deleting Dpy30 …


Regulation Of Effector Cd4 T Cell Pathogenicity During Chronic Inflammation, Boyoung Shin Jan 2018

Regulation Of Effector Cd4 T Cell Pathogenicity During Chronic Inflammation, Boyoung Shin

All ETDs from UAB

Effector CD4 T cells are essential for the balance between pro- and anti-inflammatory immune responses during homeostasis. Dysregulation of effector CD4 T cell responses results in chronic inflammatory disorders such as Inflammatory Bowel Disease (IBD) and Multiple Sclerosis (MS), however therapeutic options for these diseases are limited. Understanding the mechanisms that regulate pathogenicity of effector CD4 T cells is critical to devise new therapeutic interventions. Herein we show two different mechanisms that profoundly impact pathogenic potential of CD4 T cells by regulating heterogeneities of effector functions and differentiation states. Different subsets of effector CD4 T cells utilize distinct metabolic pathways. …


Attachment Of Streptococcus Pneumoniae Capsular Polysaccharide To The Cell, Thomas Robbin Larson Jan 2017

Attachment Of Streptococcus Pneumoniae Capsular Polysaccharide To The Cell, Thomas Robbin Larson

All ETDs from UAB

Streptococcus pneumoniae is an important human pathogen. The major virulence factor for S. pneumoniae is the capsular polysaccharide (CPS). Proper expression and localization of the CPS is essential for pathogenesis. Despite the importance of the proper transfer to the cell surface of this virulence factor, no studies have shown the exact structure and attachment to either the cell wall or membrane. Using the S. pneumoniae serotype 2 CPS as a model, which is synthesized by the widespread Wzy mechanism, we found that the CPS attaches to the cell wall β-D-N-acetylglucosamine (GlcNAc) of peptidoglycan (PG) via a direct glycosidic linkage. This …

Autophagy In Mitochondrial Quality Control And Proteotoxicity In Neurons, Matthew Redmann

All ETDs from UAB

Parkinson’s disease (PD) is the 2nd most common neurodegenerative disorder with aging as a significant risk factor. Sharing with aging brains, postmortem PD brains exhibit cellular deficits including autophagic dysfunction, mitochondrial dysfunction, and intracellular protein aggregates of alpha-synuclein. This dissertation will focus on the interplay between these key disease features. To that end, we coupled primary cortical neuronal cultures from either rats or mice with Seahorse extracellular flux, metabolomics and biochemical techniques. Autophagy is an important cell recycling program responsible for the clearance of damaged proteins and organelles. Bafilomycin A1 and chloroquine are compounds that inhibit autophagy by targeting the …


Statin Prescribing, Adherence, And Recurrent Vascular Events: A Study Of Ischemic Stroke Survivors, Karen C. Albright Jan 2017

Statin Prescribing, Adherence, And Recurrent Vascular Events: A Study Of Ischemic Stroke Survivors, Karen C. Albright

All ETDs from UAB

Due to increase in incidence and improvements in stroke mortality, the number of stroke survivors will increase over the next decade; each stroke survivor is at risk for recurrent stroke. Thus, identifying populations with the highest risk and ensuring they receive evidence-based secondary stroke prevention (SSP) is paramount. This includes ensuring access and adherence to statins. The American Heart Association (AHA)/American Stroke Association (ASA) Scientific Statement on Racial-Ethnic Disparities in Stroke Care reported that recurrent stroke risk is higher among blacks than whites and suggested that lower adherence to current standards of SSP in blacks might help explain these discrepancies. …


Endogenous Interferon-Β Regulates Survival And Development Of Transitional B Cells, Jennie Ann Hamilton Jan 2017

Endogenous Interferon-Β Regulates Survival And Development Of Transitional B Cells, Jennie Ann Hamilton

All ETDs from UAB

The survival responses of transitional B cells play a key role in shaping the development of mature, antibody producing B cells. Abnormal transitional T1 B cell survival responses are associated with the generation of polyreactive self-antigen-reactive mature B cells in systemic lupus erythematosus (SLE). Type I interferon (IFN) dysregulation is strongly associated with autoantibodies (autoAbs) and disease flares, particularly in African American (AA) patients. B cells produce a variety of immune-modulatory cytokines, but B cell production of high affinity IFNβ in SLE has not been investigated. In the present study, analysis of PBMCs from SLE patients (n=34) and healthy controls …

Osteoblast And Chondrocyte Specific Contribution Of The Runx2 Gene During The Development Of Cleidocranial Dysplasisa, Kayla Renee King

All ETDs from UAB

The Runx2 transcription factor is essential for the differentiation of mesenchymal stem cells into functional chondrocytes and osteoblasts. In humans, the haploinsufficiency of the Runx2 gene is associated with cleidocranial dysplasia (CCD). The CCD is characterized by short stature, open sutures and fontanels in the skull, hypoplastic clavicles and supernumerary teeth. Skeletal elements disrupted in CCD patients are developed by intramembranous and/or endochondral ossification. However, the cell type specific roles of the Runx2 gene in the development of CCD-associated skeletal defects remain unknown. The main goal of this research was to define the specific role of the Runx2 gene in …


The Role Of Hur In Astrocytes In Spinal Cord Injury, Thaddaeus Kwan Jan 2017

The Role Of Hur In Astrocytes In Spinal Cord Injury, Thaddaeus Kwan

All ETDs from UAB

Neuroinflammation is a defining event during the acute phase of spinal cord injury (SCI). The inflammatory cascade is initiated by activated glial cells such as astrocytes and microglia in the milieu of the injured tissue through release of pro-inflammatory cytokines, matrix metalloproteinases, and reactive oxygen species. These soluble factors produce cytotoxicity to neurons and other cells either directly or indirectly by promoting permeabilization of the blood-spinal cord barrier, edema and subsequent ischemia. These factors also serve to recruit and activate additional glia and peripheral immune cells. The mRNAs of many of these soluble factors such as TNFα, IL-1β, CXCL1, and …

The Function Of Protein Kinase Ck2 In Cd4 T Cell Differentiation And Autoimmunity, Sara Ann Gibson

All ETDs from UAB

Protein kinase CK2 is a highly conserved serine/threonine kinase essential for cell viability. CK2 exhibits immense pleiotropy and has well characterized interactions with canonical cytosolic signaling pathways such as PI3K/Akt/mTOR and JAK/STAT. These pathways are critical for CD4+ T cell function, and further are known to be aberrantly active in the T cell-driven autoimmune disease Multiple Sclerosis, but little is known as to how CK2 functions in CD4+ T cells or in the context of autoimmune diseases. The current dissertation examines the understudied T cell-specific functions of CK2 utilizing two approaches, pharmacologic inhibition and genetic deletion. We discovered CK2 to …

Mechanism Of Cytomegalovirus-Induced Mucosal Inflammation, Evida Adiko Dennis Jan 2017

Mechanism Of Cytomegalovirus-Induced Mucosal Inflammation, Evida Adiko Dennis

All ETDs from UAB

Cytomegalovirus (CMV) is an opportunistic β-herpesvirus that causes severe mucosal inflammation in recipients of organ and stem cell transplants, HIV-1-infected subjects, and persons with inflammatory bowel disease. The gastrointestinal mucosa is among the most common sites of CMV inflammatory disease, and the inflammatory lesions associated with CMV mucosal infection contain infected macrophages and increased levels of macrophage-derived cytokines, implicating mucosal macrophages in the inflammatory process. Paradoxically, in healthy human intestinal mucosa, macrophages are profoundly down-regulated for pro-inflammatory responses (inflammation anergy) due to stromal TGF-β-induction of Smad signaling and inactivation of NF-κB. To elucidate the mechanism whereby CMV promotes macrophage-mediated mucosal …

N-Acetyl-D-Glucosamine-Reactive Natural Antibodies: Roles In Suppression Of Autoimmune Diabetes And Environmental Factors Influencing Their Development, James Stewart New

All ETDs from UAB

Type 1 Diabetes suppression in diabetes prone mice following immunization with Group A Streptococcus correlates with the B lymphocyte response to N-acetyl-D-glucosamine (GlcNAc) present in the Group A Carbohydrate cell wall polysaccharide. GlcNAc-specific B cells recognize cryptic GlcNAc-epitopes in beta cells. Following exposure of GlcNAc-modified antigens on beta cells during cellular apoptosis, GlcNAc-specific IgM antibodies opsonize these epitopes and mediate classical complement pathway activation. In vitro, opsonization of apoptotic beta cells with GlcNAc-specific IgM increases their uptake by dendritic cells, while suppressing the subsequent presentation of beta cell-derived antigens to diabetogenic T lymphocytes. Passive administration of Group A Streptococcus antisera …

All ETDs from UAB

Anxiety disorders are the most commonly diagnosed mental illness in the United States. Yet current treatment options are of limited efficacy, resulting in chronic disability for many patients. A greater mechanistic understanding of the neural states that cause anxiety behavior is necessary to develop better treatments for anxiety disorders. Since rodent models provide greater opportunity for investigating cellular and molecular under-pinnings of anxiety-like behavior, the present studies utilized rats bred for High Response to novelty (High Responders, HRs) and Low Response to novelty (Low Responders, LRs) which naturally exhibit low and high levels of anxiety respectively. Because the HR/LR anxiety …


Tgf-Β Regulates The Stability Of Sox9 In Cartilage, George Coricor Jan 2017

Tgf-Β Regulates The Stability Of Sox9 In Cartilage, George Coricor

All ETDs from UAB

One out of two people in the U.S. will experience some form of Osteoarthritis (OA) in their lifetime. Members of the Transforming Growth Factor-β (TGF-β) superfamily are important factors that stimulate chondrocyte matrix biosynthesis. Mice with a dominant-negative mutation of the TGF-βIIR develop a degenerative joint disease resembling OA. Another key chondrogenic factor, SOX9, is important for maintaining chondrocyte function. SOX9 and TGF-β receptors are decreased in OA patients. Our overall hypothesis is that TGF-β regulates SOX9 to maintain articular cartilage. We utilized two cell culture models for these experiments, ATDC5 cells, and primary bovine articular chondrocytes. We showed that …


Elucidating The Cellular Function Of The N-Terminal Domain Of Tyrosyl-Dna Phosphodiesterase I, Selma Marcela Cuya Jan 2017

Elucidating The Cellular Function Of The N-Terminal Domain Of Tyrosyl-Dna Phosphodiesterase I, Selma Marcela Cuya

All ETDs from UAB

Tyrosyl-DNA phosphodiesterase I (Tdp1) is a conserved eukaryotic DNA repair enzyme that removes adducts from DNA-ends. This includes DNA topoisomerase I (Top1)-DNA covalent complexes reversibly stabilized by camptothecins (CPTs). Tdp1s two-step catalytic cycle requires the action of its nucleophilic histidine (Hisnuc) that detaches the adduct by forming a Tdp1-DNA adduct, and its general acid/base histidine (Hisgab) to activate water, thereby releasing Tdp1 from the DNA-end. Tdp1 expression is associated with genomic instability, cancer etiology, chemotherapeutic resistance, and SCAN1-neurodegeneration, via Tdp1HisgabArg catalytic mutant. Our lab has characterized substitutions of the catalytic histidines in both yeast and human cell models. These substitutions …

Effects Of Maternal And Child Depressive Symptoms And Child’S Perceived Stress On Glycemic Control As Mediated By Cortisol In Prepubertal Children With Type 1 Diabetes, Sara Laubinger Davis

All ETDs from UAB

Introduction: Type 1 diabetes (T1D) is one of the most common diseases of childhood affecting over 167,000 children under the age of 20. Despite adequate insulin regimens and concurrent treatments, many children still have trouble achieving glycemic control as evidenced by elevated HbA1c levels. Previous research indicates that parent-child interactions and parental involvement in diabetic care influence glycemic control. However, these relationships may be impaired in mothers with depressive symptoms or in children who have high levels of depressive symptoms or perceived stress. Moreover, cortisol, a stress hormone, may mediate the proposed relationships. Therefore, the purpose of this study was …

Resin Infiltration Of Incipient Interproximal Caries: A 6-Month Randomized, Controlled Clinical Trial, Purvi Vaghela

All ETDs from UAB

Dental caries is the most widespread of all diseases. It causes destruction of tooth structure by dissolving the enamel first, then progressing to the dentin. While it is possible to replace carious tooth structure with invasive restorations, it is highly desirable to arrest or reverse the disease process so that the restorations can be avoided. One of the most difficult areas to clean or use preventive, non-surgical treatment is the contact area between teeth. Recently treatment with resin polymers to infiltrate enamel and dentin affected by caries has been in-troduced. The infiltration technique arrests the lesion progression by penetrating and …

The Functional Role Of Toll-Like Receptor 4 In The Renal Microcirculation., Justin Pieter Van Beusecum

All ETDs from UAB

Renal autoregulation is an intrinsic property of afferent arterioles that maintains a stable RBF, glomerular capillary pressure, and GFR, while protecting the glomeruli against fluctuations in arterial pressure. Recently it has been reported that immune system activation and inflammation have been linked to impairment of renal autoregulatory behavior. Evidence suggests that activation of toll-like receptor 4 (TLR4) plays an important role in the progression of AKI and CKD. The contributions of innate immune system activation, TLR4 and renal autoregulatory dysfunction remain unknown. This dissertation explores the novel concept that both acute and chronic TLR4 activation leads to the attenuation of …
