St6gal-I Mediated Sialylation Promotes Pancreatic Ductal Adenocarcinoma Progression And Chemoresistance, Asmi Chakraborty
All ETDs from UAB
ST6Gal-I adds α2-6 sialic acids to select N-glycosylated cell surface receptors, thereby modulating receptor function and intracellular signaling. ST6Gal-I is upregulated in various carcinomas and confers cancer stem cell (CSC) properties evidenced by tumorspheroid growth, chemoresistance and tumor initiating potential. In pancreatic ductal adenocarcinoma (PDAC), ST6Gal-I conferred gemcitabine resistance by abrogating DNA damage and altering expression levels of gemcitabine metabolism genes. Further, ST6Gal-I promoted resistance to chronic gemcitabine treatment. Additionally, metastatic clones of a PDAC cell line had increased ST6Gal-I expression and ST6Gal-I knockdown enhanced gemcitabine sensitivity. To investigate the physiological consequences of ST6Gal-I in PDAC, murine models were used. …

All ETDs from UAB
Dental caries, commonly known as tooth decay, is the most common infectious disease worldwide. The main etiological agent of dental caries is Streptococcus mutans which can readily form a biofilm on the surface of teeth and produce acids through the metabolism of dietary sugars, which is largely responsible for the demineralization and subsequent destruction of tooth enamel. In addition, S. mutans synthesizes extracellular glucosyltransferases (Gtfs) capable of breaking apart dietary sucrose and polymerizing the glucose subunits into the sticky glucan matrix of the biofilm, imperative for the formation of robust, three-dimensional biofilms. Currently used caries therapies are not species-specific and …

All ETDs from UAB
Protein homeostasis is an emerging component of schizophrenia (SZ) pathophysiology. Proteomic alterations in SZ are well-documented; however the underlying mechanism driving these changes remains unknown. The ubiquitin proteasome system (UPS) is fundamental to protein homeostasis regulation, and UPS transcript abnormalities in both blood and brain have been observed in SZ. Supporting a role for UPS dysfunction in SZ, we have reported decreased protein expression of ubiquitin-associated proteins in SZ brain. However, previous work on the proteasome has been limited to transcript expression. In the following studies we sought to address this gap in knowledge by characterizing proteasome dysfunction in the …

Reported Clinical And Financial Performance Of Hospitals With Physician Ceos Compared To Those With Nonphysician Ceos, Leon Moores
All ETDs from UAB
Leaders impact organizational behavior and performance, and CEOs may have greater impact via numerous proposed mechanisms. Because of this, organizations expend considerable resources recruiting and selecting CEOs and may benefit from information suggesting a positive impact on organizational performance based upon measurable CEO characteristics. Little work has been done comparing the performance of hospitals with physician CEOs versus non-physician CEOs, in spite of the ease of identification of this characteristic and extant leadership theories suggesting a relationship between technical expertise and success in leading highly technical organizations. We compared multiple measures of reported clinical and financial performance and our linear …

All ETDs from UAB
Background: People with disabilities (PWDs) have poorer health outcomes, yet are they are underserved by public health initiatives. PWDs face numerous barriers to participation in community-based health programs despite mounting evidence about these barriers along with recommendations and guidelines to become more inclusive of disability. Policy, system, and environmental (PSE) changes that are inclusive of PWDs can help create access to health promotion programs for PWDs. Systematically implementing inclusive PSE changes using implementation science principles can support effective and sustainable changes are implemented for each unique community context. The purpose of this dissertation is to explore the experiences of public …

Impact Of Environmental Exposures On Respiratory Health, Lawrence Rasmussen
All ETDs from UAB
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality around the world. Cigarette smoking is a leading cause of COPD; similarly, individuals exposed to secondhand smoke (SHS) are also vulnerable to COPD and other airway diseases; however, distinct molecular mechanisms involved in SHS-induced lung effects that result in COPD are poorly understood. Mucociliary clearance (MCC) is a primary lung defense against inhaled particulate matter and pathogens. Thus, understanding how inhaled irritants such as SHS disrupt MCC will promote improved scientific understanding and better public health initiatives to prevent respiratory illnesses. Using a variety of in vitro …

Acetylcholine Signaling In Glioblastoma Invasion And Peritumoral Hyperexcitability, Emily Grace Thompson
All ETDs from UAB
Glioblastomas are the most common and deadly form of primary brain cancer in adults. Current treatment strategies are aggressive, including a combination of surgical resection, radiotherapy, and chemotherapy. However, median patient survival has remained stagnant at 12 to 15 months for the last several decades. This dismal patient outcome has prompted efforts to understand the unique characteristics of these tumors, since traditional therapeutics have not been efficacious. Extensive invasion is a salient feature of glioblastomas that significantly diminishes the effectiveness of current treatment strategies and is ultimately the cause of tumor recurrence within 2 years in approximately 80% of patients. …

Endothelial N-Glycan Hypoglycosylation Enhances Cd16+ Monocyte Adhesion: A Role For Alpha-Mannosidases, Kellie Regal Mcdonald
All ETDs from UAB
Monocyte extravasation through the endothelial layer is a hallmark of atherosclerotic plaque development and is mediated by heavily glycosylated surface adhesion molecules, such as intercellular adhesion molecule-1 (ICAM-1). Human monocytes have been classified into three distinct groups: classical (anti-inflammatory; CD14+/CD16-), nonclassical (patrolling; CD14+/CD16++), and intermediate (pro-inflammatory; CD14++/CD16+). The CD16+ nonclassical / intermediate monocytes have been implicated in atherosclerosis progression and their levels positively associate with adverse cardiac events. However, there is a relative lack of understanding as to whether there are distinct mechanisms that regulate CD16+ vs. CD16- monocyte adhesion to the inflamed endothelium. Our previous data identified a high-mannose …

External Root Resorption In The Orthodontic Patients, Frank Earl Litchfield
All ETDs from UAB
External Apical Root Resorption (EARR) is a side effect of orthodontic treatment that results in root shortening in about one-third of orthodontic patients. Great variability among patients exists in their susceptibility to this multifactorial condition, and both treatment and patient specific factors contribute to EARR. Root resorption values were found to be higher in Hispanics compared to Asians and Caucasians (1). However, the prevalence of EARR is not well documented in all populations. Since African Americans represent the largest minority group in the United States, establishing the prevalence and risk factors for EARR within this ethnicity is important. Objective: To …
The Mechanism Of Glucose-Induced Trib3 Expression In Myoblasts And Myotubes, Xiaobing Liu
The Mechanism Of Glucose-Induced Trib3 Expression In Myoblasts And Myotubes, Xiaobing Liu
All ETDs from UAB
Our previous data indicates that glucose-toxicity is dependent upon upregulation of TRIB3 expression in muscle. TRIB3 is a glucose-responsive gene and, as a pseudokinase, it blocks phosphorylation of AKT resulting in insulin resistance. The purpose of the current study was to identify the role of the differentiation process and the minimal functional sequence of TRIB3 promoter region in modulating glucose-induced TRIB3 gene expression in C2C12 myocytes. First, C2C12 myocytes were collected every 48 hours during the whole differentiation, totally 4 intervals. Before collection, cells were treated with either 5mmol glucose or 25mmol glucose for 24 hours. Under 5mmol glucose, the …

Associations Between Dietary Fat Intake And Waist Circumference, Phonchit Teng Soukhamneut
All ETDs from UAB
The objective of this study was to assess: 1) trends in dietary fat intake from 2003-2016 2) the association between type of dietary fat intake and waist circumference (WC), 3) the association between type of dietary fat intake and body shape, and 4) whether these associations vary by sex and race/ethnicity. This secondary data analysis included 27,057 adults aged 19 to 65 from the National Health and Examination Survey (NHANES) 2003-2016. For WC, participants were categorized into high-risk (men: WC ≥ 40 in; women: WC ≥ 35 in) and low-risk (men: WC < 40 in; women: WC < 35 in). Total fat intake was categorized as high (TOTFAT ≥ 35%) and low (TOTFAT< 35%). Saturated fat intake was categorized into high (SATFAT ≥ 10%) and low (SATFAT < 10%). Unsaturated fat intake was categorized into high (UNSATFAT ≥ 25%) and low (UNSATFAT < 25%). Logistic regression was performed to assess the associations between DFI and WC and DFI and body shape, controlling for age, BMI, and total caloric intake. NHW men with high TOTFAT were found to have 1.41 (OR: 1.41, 1.19 – 1.68) times the odds of having a high-risk WC compared to men with a diet low in TOTFAT, controlling for age, BMI, and total caloric intake. NHW men with a diet high in SATFAT were at increased odds of having a high-risk WC compared to men with a diet low in SATFAT, after controlling for covariates (OR: 1.49, 1.21 -1.84). NHW men with a diet high in UNSATFAT were at increased odds of having a high-risk WC compared to men with a diet low in UNSATFAT after controlling for covariates (OR: 1.375, 1.09 – 1.74). There were no significant associations found among NWB and MA men for any type of dietary fat intake. For women, no associations were found between type of dietary fat and WC by race/ethnicity. There were no associations between DFI and body shape by race/ethnicity groups and sex. Future studies are needed to further investigate the body shape cut-off points for increased risk associated with chronic disease.

Characterization Of Chemical Uptake And Aryl Hydrocarbon Receptor Mutations In Zebrafish, Jaclyn Paige Souder
All ETDs from UAB
In a society driven by technology and industry, we must be increasingly aware of how changes to our environment impact our health. This is especially true concerning embryonic development, which is easily influenced by extra-embryonic factors, including environmental contaminants. Determining how exogenous compounds are absorbed, which receptors they act through, and how these receptors act endogenously is important to fully understand to what extent developmental exposures impact fetal and adult health. I have used the zebrafish model system to address these questions for two classes of environmentally-relevant chemicals—estrogens and dioxins. First, I developed an assay to measure the uptake of …

The Role Of Protein Synthesis Attenuation And Eif2-Alpha Phosphorylation In Retinal Degeneration, Christopher Ryan Starr
All ETDs from UAB
Inherited retinal degeneration is a class of diseases in which there is no cure and very few treatment options available. An activated unfolded protein response has been detected in various animal models of retinal degenerative diseases. Several groups have found heightened activation of one pathway of the unfolded protein response in particular, the protein kinase R-like endoplasmic reticulum kinase signaling cascade, which converges on and phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 to transiently halt protein synthesis and allow the cell to reestablish homeostasis. Although it is widely accepted that this signaling is inherently protective, hyperactivity or …

Bet Bromodomain Inhibition As An Approach For Treatment Of Cholangiocarcinoma, Samuel Charles Fehling
All ETDs from UAB
Cholangiocarcinoma (CCA) is a highly aggressive neoplasm which arises from the epithelial layer of the biliary tract. It is the second most common primary hepatic malignancy. As CCA is typically diagnosed at late disease stage, the current standard of care, resection followed by gemcitabine with cisplatin, is not effective. Further, up to 90% of CCA patients are ineligible for resection. Of those eligible for resection, postoperative chemotherapy does not prolong overall survival leading to a 5-year survival of ~30%. Previously, mutations have been identified in KRAS (17% of CCA cases), TP53 (44%) and SMAD4 (17%) but none have been recognized …

Identification Of Two Spop-Mediated Pathways In Prostate Cancer Progression, Joshua Fried
All ETDs from UAB
Prostate cancer is one of the most common malignancies and causes of cancer related death in men. Morbidity is primarily attributed to late-stage and metastatic disease. Re-cent genomic screening studies have revealed that the Speckle type Poz Protein (SPOP) is the most frequently altered gene by missense mutations in prostate cancer. Interestingly, all of the identified mutations were located in the substrate binding domain of SPOP. Here, two pathways highlighting the impact of SPOP mutation on prostate cancer are pre-sented. First, evidence showing that one of the naturally occurring SPOP mutations, ser-ine 119 to asparagine (S119N), induces radiosensitivity and an …

All ETDs from UAB
Introduction: Tooth agenesis is defined as the lack of development of a tooth. Maxillary lateral incisors have been reported to be missing in 2.2% of the population in the United States of America. Two treatment options are available: opening the space to restore the missing tooth with a dental prosthesis; or close the space by moving the adjacent teeth into the space and substituting the missing lateral incisor with the maxillary canine. With a wider crown and a more convex labial surface than lateral incisors, canines require a significant amount of reduction in order to achieve an adequate occlusion and …
Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey
Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey
All ETDs from UAB
Bone loss is a worldwide problem resulting in increased risk of fracture. Osteoblasts are responsible for bone synthesis; therefore, treatments promoting osteoblast differentiation and/or activity would result in increased bone formation. The regulation of DNA accessibility is a key mechanism controlling gene expression and cellular differentiation. BAF (BRG1 Associated Factor) mediated chromatin remodeling increases DNA accessibility by sliding or ejecting nucleosomes. This process can occur in a cell type specific manner based on the composition of BAF. In many tissue types, a unique combination of BAF subunits has been identified to be responsible for the maintenance or differentiation of that …

A wide range of infections is attributed to the pathogenesis of Gram-positive bacteria. The emergence of multi-drug-resistant Gram-positive pathogens has been a significant health concern and present serious therapeutic challenges globally. Some of the common Gram-positive bacterial species like Streptococcus pneumonia, Group B Streptococcus, and Staphylococcus aureus are infectious by employing several virulence factors for initial adhesion, colonization, biofilm initiation and dispersion, complement evasion, nutrient acquisition, and infection. The structural insights into these virulence factors are essential for understanding their mode of action, and also for developing a new class of antibiotics; a significant interest of many researchers. Pneumococcal adhesive …
Appropriately Timed Epigenetic Manipulation With Histone Deacetylase Inhibitors As A Platform Approach To Tumor Immunotherapy, Tyler Mccaw
All ETDs from UAB
In contrast to chemotherapy and radiotherapy, immunotherapy is able to respond in proportion to tumor burden and continue to evolve in parallel with the tumor mass and metastatic sites. In this way, immune-based cancer therapies are a living drug and hold enormous potential. In this work, we enforce expression of MHCII on a murine breast cancer model to study how changes in tumor biology can drive improved T cell-mediated responses. We next use histone deacetylase inhibitors to manipulate the microenvironment through a more clinically relevant, therapeutic approach. Herein, improvements in tumor control were driven by CD8 T cells and IFNγ, …
