Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
All ETDs from UAB
Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a channel responsible for the transport of chloride and bicarbonate ions across the apical cell surface. In the respiratory tract, defective CFTR results in viscous and adherent mucus that becomes static within the airway, which leads to chronic infections, progressive lung damage, and early mortality. Historically, CF mucus stasis has been attributed to significant airway dehydration; however, growing evidence has demonstrated that aberrant electrostatic properties of mucins also contribute to mucus stasis in CF. Mucins are large, polymeric glycoproteins …
Non-Catalytic Regulators Of The Secretory Pathway, Peyton Vanwinkle
Non-Catalytic Regulators Of The Secretory Pathway, Peyton Vanwinkle
All ETDs from UAB
This thesis focuses on two key questions: 1) how are bone development and regeneration regulated by the CREB3L1 transcription factor; and 2) what is the mechanism of action of the endoplasmic reticulum resident protein JAGN1, which when dysregulated, causes severe congenital neutropenia (SCN)? CREB3L1 regulates bone development and regeneration in mammalian models by facilitating the expression of COL1A1 and components of the secretory pathway required for collagen secretion. We generated two zebrafish models of Creb3l1 dysfunction (creb3l1ΔbZIP/ΔbZIP and creb3l1TA+/TA+). Both models showed that Creb3l1 functions in regulating col1a1a transcription and overall regenerate size are conserved in zebrafish. However, we also …

Chronic kidney disease (CKD) is characterized as irreversible progressive loss of renal function and affects over one tenth of the global population. Although CKD-associated comorbidities contribute significantly to its mortality, the lungs are often not considered. Lung diseases make up three of the top six leading causes of death worldwide and share many comorbidities with CKD. Clinical reports show that CKD patients are more likely to develop obstructive and restrictive lung diseases, but the mechanisms underlying this propensity for CKD-associated pulmonary complications are unknown. Hyperphosphatemia and associated elevations of fibroblast growth factor (FGF) 23, two of many consequences of reduced …
Catecholamines And Catecholamine Resistance In Animal Models Of Metabolic Syndrome, Robert Follett Rosencrans
Catecholamines And Catecholamine Resistance In Animal Models Of Metabolic Syndrome, Robert Follett Rosencrans
All ETDs from UAB
The sympathetic nervous system is a key regulator of energy homeostasis, in part, through the control of white adipose tissue lipolysis. Sympathetic nerves modulate adipose tissue physiology through the release of catecholamines, particularly norepinephrine, onto alpha- and beta-adrenergic receptors (a-AR; B-AR). Lipolysis refers to the breakdown of triglycerides into glycerol and free fatty acids, often in response to activation of B2/3-AR. Beta adrenergic activation of lipolysis is widely known to be impaired in patients with metabolic syndrome and animal models thereof (catecholamine resistance). Recent studies have demonstrated that catecholamine regulation of adipokine release is also disrupted, suggesting that catecholamine resistance …

Investigating Hiv-1 Transmission To Human Cervix Using Reporter Virus Technologies, Dana Frances Indihar
All ETDs from UAB
Around 39 million people globally are currently infected with Human immunodeficiency virus 1 (HIV-1), more than half of whom are women. HIV-1 is a retrovirus that infects and depletes an individual’s immune cells, culminating in the development of acquired immunodeficiency syndrome (AIDS) if not managed with anti-retroviral therapies (ART). Most women acquire HIV-1 through heterosexual intercourse. However, the early mechanisms and virologic determinants of HIV-1 transmission to women remain unclear. Herein, we demonstrate transmitted/founder (TF) HIV-1 representing two genetically and pathogenically distinct subtypes (A and D) in vivo have distinct replication phenotypes in an ex vivo cervical explant tissue (CET) …

Novel Roles Of Rab35 In Development And Disease, Kelsey Ruth Clearman
All ETDs from UAB
As the largest and most dynamic family of GTPases within the mammalian cell, Rabs play an essential role as molecular switches in regulating intracellular vesicular trafficking and serve as significant signaling transducers. Over the last few decades, Rabs have been identified to regulate endocytic, transcytosis, and exocytotic pathways, and mutations in Rabs, or alterations in downstream effectors lead to embryonic lethality and diseases such as cancer and ciliopathies. Ciliopathies are a class of pathologies that result from defects in structure or function of the primary cilia. Primary cilia, found on virtually all mammalian cells, is a microtubule-derived appendage that relies …
The Role Of Fibroblast Growth Factor Receptors In Inflammatory Airway Diseases, Molly Easter
The Role Of Fibroblast Growth Factor Receptors In Inflammatory Airway Diseases, Molly Easter
All ETDs from UAB
Chronic inflammation plays a role in the development and progression of airway diseases such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF). COPD is caused primarily by chronic cigarette smoke exposure. Conversely, CF is a single gene disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR). Although the causes of COPD and CF are different, there are common pathological features. Studies show that chronic inflammation plays a significant role in the pathogenesis of both COPD and CF. Moreover, chronic inflammation induces ageing-associated pathomechanisms like cellular senescence, which exacerbates chronic inflammation. Previous work demonstrates that …

Application Of Machine Learning And Network Approaches To Prioritize Safe And Efficacious Drug Repurposing Candidates, Jennifer L. Fisher
All ETDs from UAB
Only ten percent of drugs in clinical trials are ultimately approved by the Food and Drug Administration (FDA). With many diseases and disorders needing therapeutic options, computational drug repurposing methodologies are great alternatives to some drug discovery methods due to quicker FDA approval and lower cost. We sought to gain insights to improve the identification of drug repurposing candidates that will be safe and effective to increase the success of computational drug repurposing approaches. In regards to identifying safe drug candidates, pharmacovigilance studies of adverse event case reports identified that women are more likely to experience an adverse event, and …

Select Lipid Signaling. Derived From T-Cells Is An Important Contributor To Type 1 Diabetes Development, Tayleur White
All ETDs from UAB
We reported that Ca2+-independent phospholipase A2β (iPLA2) contributes to type 1 diabetes (T1D) development; however, the impact of lipid signaling from T-cells is unknown. To address this, we first administered splenocytes from NOD, NOD.iPLA2+/- (NOD.HET), or NOD.iPLA2-/- (NOD.KO) mice to 4-week-old NOD.scid recipients. As expected, T1D onset was rapid in NOD cell recipients and 100% by 12 weeks. However, onset was delayed by 1-3 weeks in NOD.HET or NOD.KO cell recipients and only 60% became diabetic, suggesting a role for T-cell iPLA2. Next, to establish importance of iPLA2 in CD4 or CD8 cells, purified cells were administered to NOD.scid mice. …
The Effects Of Cannabidiol On Brain Temperature In Treatment-Resistant Epilepsy, Ayushe A. Sharma
The Effects Of Cannabidiol On Brain Temperature In Treatment-Resistant Epilepsy, Ayushe A. Sharma
All ETDs from UAB
Epilepsy affects over 70 million people worldwide with a global incidence of 2.4 million new cases per year. In many of these patients, neuroinflammation (NI) is a key pathological contributor to focal seizure generation and maintenance. Sustained NI degrades the blood–brain barrier, leads to neuronal death, and ultimately decreases seizure threshold. Finding ways to image and treat NI is especially important for the >30% of patients with treatment-resistant epilepsy (TRE) who cannot achieve seizure freedom with standard antiseizure medications. Cannabidiol (CBD) effectively reduces seizure frequency and severity in many TRE patients, although its antiepileptic effects remain poorly understood. Atypically high …

Interactions Between Pseudomonas Aeruginosa And The Oral Commensal Streptococcus Salivarius, Sara Noelle Stoner
All ETDs from UAB
The cystic fibrosis airway is a polymicrobial environment often dominated by opportunistic pathogens such as Pseudomonas aeruginosa, a leading cause of lung function decline and mortality in persons with CF. Commensal streptococcal colonization has been associated with stable CF lung function in multiple studies. However, few studies have examined interactions between P. aeruginosa and commensals as well as their impact on P. aeruginosa airway infections. In the first half of this work, we studied interactions between P. aeruginosa and the oral commensal Streptococcus salivarius within a biofilm setting. We found that S. salivarius biofilm formation is promoted by the non-mucoid …

Multi-omics data analysis, integrating various molecular layers such as genomics, transcriptomics, epigenomics, proteomics, and metabolomics, provides a comprehensive approach to characterize the molecular landscape of cancer differences. By integrating diverse omics data, researchers can identify genetic variations, gene expression patterns, epigenetic modifications, and protein alterations that contribute to differences in cancer progression, and treatment response. These molecular features can serve as potential biomarkers for predicting patient outcomes and guiding personalized treatment strategies. Furthermore, multi-omics data analysis enables the identification of molecular subtypes specific to different …
Modular Regulation And Function Of The Polypyrimidine Tract Binding Protein 1 (Ptbp1), Christine Carico
Modular Regulation And Function Of The Polypyrimidine Tract Binding Protein 1 (Ptbp1), Christine Carico
All ETDs from UAB
RNA binding proteins (RBPs) are critical regulators of gene expression as they are responsible for the chaperoning and processing of every nascent RNA transcript. Many studies have investigated mechanisms of specificity of RBP function and have identified factors such as cell-specific expression of RBPs and differential preferences for RNA secondary structure. However, RBPs are often multi-domain proteins that contain repeats of various RNA binding domains (e.g., RNA recognition motif) and little work in the genomic era of transcriptomic interrogation has been done to define the contribution of individual domains to the overall protein function. Polypyrimidine tract binding protein 1 (PTBP1) …

Reduction Of Sphingomyelinases Associated With Progranulin Deficiency And Frontotemporal Dementia, Nicholas R. Boyle
All ETDs from UAB
Frontotemporal dementia (FTD) is a leading cause of early-onset dementia and has a significant socioeconomic burden due to difficulties in diagnosis and delay to diagnosis. FTD is a clinically, pathologically, and genetically heterogeneous disorder. The pathological changes associated with FTD are termed frontotemporal lobar degeneration (FTLD). Protein aggregates are always present in FTLD, with >90% of cases presenting with either TDP-43 or tau pathology. Most cases of FTD are sporadic, but familial cases account for up to 25% of FTD. All familial FTD is inherited in an autosomal dominant fashion with most cases being caused by mutations in tau (MAPT), …

Sialylation Of Epidermal Growth Factor Receptor By The Sialyltransferase St6gal1 Modulates Receptor Activity And Downstream Signaling, Katherine Ankenbauer
All ETDs from UAB
During the process of malignant transformation, cells have striking changes in their cell surface glycosylation. One of these changes is an enrichment for α2,6 sialic acid which is added by the sialyltransferase, ST6GAL1. ST6GAL1 is upregulated in numerous malignancies and acts by adding an α2,6 sialic acid onto receptors bound for the plasma membrane. This sialic acid, in turn, modulates the activity of the receptor by regulating conformation, clustering, and cell surface retention. The work presented in this dissertation focuses on how ST6GAL1-mediated sialylation of a specific cell surface receptor, epidermal growth factor receptor (EGFR), regulates many of its properties. …

Autoimmune diseases are a classification of more than eighty diseases where the immune system recognizes a self-antigen and mistakenly attacks the body’s own tissue, inducing inflammation a nd p otentially l eading t o d amage. Autoimmune diseases disproportionately affect women and develop at any age depending on the disease. The prevalence of some autoimmune diseases is increased in minority populations. Despite this, research into higher-risk populations is lacking. This highlights the need to contribute research into understanding autoimmune disease pathogenesis in diverse studies to understand why disease is more severe in these populations. We analyzed transcriptomes and methylomes of …

Aberrant Signal Transduction Of Neuronal Injury: Trauma And Toxicology, Alan Umfress
All ETDs from UAB
Neurological injuries occur in epidemic proportions worldwide. Neuronal injuries are events resulting in damage to the central nervous system (CNS) that impair neurological function. Subsequent impairments in neuronal function can be rapid, existing immediately after injury, or progressive and chronic impairments that persist for the lifetime of the survivor. CNS injury constitutes a broad class of environmental and pathophysiological insults ranging from blunt-force trauma to the brain or spinal cord, to acute ischemic and hemorrhagic strokes, and insults resultant from neurotoxic agents. While divergent in initial cause, many of these insults share underlying pathophysiological outcomes including excitotoxic cell signaling, neuroinflammation, …

All ETDs from UAB
Breast cancer is one of the most common and deadly cancers diagnosed in women each year. The HER2-positive subtype of breast cancer is associated with poor prognosis and lower progression-free survival. Early identification of HER2 expression is extremely important for the effective treatment of the disease. Current methods to diagnose HER2-positive breast cancer involve invasive biopsies to semi-quantitatively determine the amount of HER2 expression. However, many lesions are often unavailable for biopsy due to their location and there may be variable HER2 expression between the primary tumor and metastasis. Positron emission tomography (PET) can give a full-body, non-invasive evaluation of …

Neutrophil Heterogeneity And Alternative Granulopoiesis In Chronic Inflammatory Conditions, Ashley N. Connelly
All ETDs from UAB
Neutrophils, the most abundant type of circulating leukocyte, represent a heterogeneous population with distinct roles in immune regulation and disease pathogenesis. A major obstacle to our understanding of neutrophil biology is that neutrophils are readily activated during preparation. The lack of standardized methodology for neutrophil characterization makes the comparison of results across studies challenging. Here we provide a careful comparison of eight characterization methods and present a novel, optimized protocol for the characterization of whole blood neutrophils minimizing activationinduced phenotypic alterations during processing. Despite successful virological control, HIV-1-infected individuals maintain an increased risk of life-threatening comorbidities including liver, cardiovascular, and …

Crucial Role Of T Follicular Helper Cell-Derived Ifn-Γ In Lung Resident Memory B Cell Responses, Nicole Michelle Arroyo-Diaz
All ETDs from UAB
T follicular helper (Tfh) cells constitute a distinct subset of CD4 T cells that reside within B cell follicles, playing an indispensable role in orchestrating the Germinal Center (GC) response. In response to polarizing environments, such as Influenza A virus infection (IAV), Tfh cells secrete effector cytokines, including IFN-γ and IL-4. Nevertheless, the specific functions of cytokine-producing Tfh cell subsets, beyond their involvement in driving class switch recombination (CSR), remain largely unexplored. Here, we demonstrate that, following IAV infection, Tfh cell cytokine production undergoes a dynamic shift, transitioning from early IFN-γ dominance to later predominance of IL-4. The initial IFN-γ …

Chronic Circadian Disruption Increases Risk For Cardiovascular Disease, Jazmine I Benjamin
All ETDs from UAB
Circadian disruption is a disturbance in biological timing which can occur within or between different organizational levels, ranging from molecular rhythms within specific cells to misalignment of behavioral and environmental cycles. Previous work has shown that changing the timing of food availability is sufficient to lower blood pressure and improve insulin sensitivity in prediabetic males, demonstrating the importance of timing of food intake for cardiovascular health. Findings from our group demonstrated that less than one week of mistimed feeding is sufficient to invert diurnal blood pressure rhythms, although kidney excretory rhythms and kidney function remained aligned with the light-dark cycle. …

All ETDs from UAB
Proteoglycans (PG) are defined as proteins with one or more covalently bound polysaccharides called glycosaminoglycan chains (GAG). PGs can either be present on the cell surface or in the extracellular matrix to mediate cellular homeostasis in normal physiology as well as exert profound roles in diseases such as cancer. PGs can interact with a host of proteins such as growth factors through their core protein and/or their GAG chains, serving as an accessory receptor to mediate signaling by binding to the ligands and altering ligand-signaling receptor binding, defined as a co-receptor function. Developmentally and in pathologies like cancer, TGF-β signaling …

All ETDs from UAB
The gain of function of nuclear factor erythroid 2 like 2 (Nrf2), in the absence of oxidative stress (or toxic insults), its pathophysiology arising from the endoplasmic reticulum and exercise intervention to mitigate the pathology are the focal point of this dissertation. Nrf2, when constitutively expressed, has been previously associated with cardiomyopathy. Chapter II investigated the hypothesis that cardiac-specific expression of Nrf2 (mNrf2-TG) would establish a pro-reductive state and trigger adaptive cardiac remodeling by enhancing the basal antioxidant defense. Through RNA profiling and imaging techniques, the study underscored that while acute preconditioning might prove advantageous against oxidative stress, prolonged pro-reductive …

A broad spectrum of human birth defects arise from the disruption of morphogenesis, the critical process through which tissues and organs acquire their proper shape. Convergent extension (CE) is a universal morphogenetic engine that promotes polarized extension of diverse tissues and organs by regulating directional cell behavior, such as oriented cell intercalation. In vertebrates, CE is regulated by non-canonical Wnt/Planar Cell Polarity (PCP) pathway, an ancient signaling pathway that was originally discovered to coordinate the cellular polarity in the plane of the epithelium. Non-canonical Wnt/PCP signaling shares the Frizzled (Fz) receptor and cytoplasmic signal transducer Dishevelled (Dvl) with the canonical …

Regulatory Elements Of Polyphosphate Biosynthesis, Marvin Qortez Bowlin
All ETDs from UAB
Polyphosphate (polyP) is an ancient, conserved, inorganic biomolecule. Biological systems have adapted many functions for this high-energy molecule, ranging from immune regulation in mammals to gene regulation in prokaryotes. Of particular interest is its use in bacterial stress responses. Bacteria use polyP to resist hazardous environmental elements like toxic molecules or nutrient starvation. In many bacterial species, polyP is synthesized by polyphosphate kinases (PPKs). PPK – discovered in Escherica coli (E. coli) – hydrolyzes adenosine-5’-triphosphate (ATP) to synthesize polyP. Species that use PPK develop multiple pathogenic defects when PPK activity is impaired, including, among others, antibiotic susceptibility. There is no …

Time-Restricted Feeding Attenuates Obesity-Induced Muscle Dysfunction Through Energy Metabolism And Microbiota Modulation, Chris Livelo
All ETDs from UAB
Obesity is a global epidemic that affects countless numbers of people caused by genetic and environmental factors including circadian disruption, which poses significant health risks to skeletal muscle physiology and other tissues. While a feeding fasting intervention known as time-restricted feeding (TRF) has been shown to mitigate obesity-related muscle dysfunction, the underlying mechanisms remain a subject of investigation. In this study, we delve into potential mechanisms underlying TRF's protective effects on muscle physiology in the context of diet- and genetic-induced obesity using Drosophila models. Our findings reveal that TRF triggers the upregulation of key genes involved in glycine production (Sardh …

Temporal lobe epilepsy (TLE) is a neurological disease marked by recurring unprovoked seizures originating from temporal lobe structures and is frequently associated with cognitive deficits. Exercise holds promise as a therapeutic approach to alleviate seizures and cognitive impairments in TLE. However, the exact cellular and molecular mechanisms by which exercise influences pathways related to seizure activity and cognition in the context of TLE still need to be understood. Neuronal network formation relies on the regulation of gene expression, which can lead to either an increase or a decrease in the production of essential proteins involved in neuronal signaling. Genes are …
