Apolipoprotein B Containing Lipoproteins Contribute To Host Innate Immune Pulmonary Defense Against Staphylococcus Aureus, Brett Manifold-Wheeler

Biomedical Sciences ETDs

Circulating lipoproteins are increasingly recognized as innate immune effector molecules. Severe hypolipidemia, which may occur with trauma or critical illness, is clinically associated with bacterial pneumonia. Importantly, pneumonia caused by Staphylococcus aureus is a major cause of morbidity and mortality in both hospital- and community-acquired pneumonia cases. Here we report that lipoprotein deficiency impairs early pulmonary innate defense against S. aureus quorum-sensing dependent pathogenesis. Specifically, apoB levels in the lung early post-infection are significantly reduced with lipoprotein deficiency, coinciding with impaired host control of S. aureus agr-signaling and increased agr-dependent morbidity and inflammation. Given that lipoproteins also inhibit LTA- and …

R-Ketorolac Targets Cdc42 And Rac1 And Alters Ovarian Cancer Behaviors Critical For Invasion And Metastasis, Yuna Guo

Biomedical Sciences ETDs

Cdc42 (cell division control protein 42) and Rac1 (Ras-related C3 botulinum) are attractive therapeutic targets in ovarian cancer based on their established importance in tumor cell migration, adhesion and invasion. Despite a predicted benefit, targeting GTPases has not yet been translated to clinical practice. Based on lead identification through high-throughput screening and computational shape homology approaches, R-ketorolac is identified as a Cdc42 and Rac1 regulator, an activity that is distinct from the anti-inflammatory, cyclooxygenase inhibitory activity of S-ketorolac. In this dissertation, R-ketorolac is established as an allosteric inhibitor of Cdc42 and Rac1. Studies on immortalized human ovarian adenocarcinoma cells (SKOV3ip), …

Exposure Of Neonatal Rats To Alcohol Has Differential Effects On Cytokine Levels In The Cerebellum And Hippocampus: Potential Role Of Microglia And Astrocytes, Lauren Topper

Biomedical Sciences ETDs

Drinking during pregnancy can result in fetal alcohol spectrum disorders (FASD), an umbrella term that encompasses a wide array of symptoms ranging from neurocognitive deficits to physical malformations. The mechanism for FASD is not yet fully understood, however recently, activation of the neuroimmune system has been suggested to play a role. Neuroinflammation, characterized by increased pro-inflammatory cytokine production and glial cell activation, has been observed following exposure to alcohol during the neonatal period. Furthermore, neuroimmune activation has been implicated in alcohol-induced neuronal death and/or damage. The studies herein investigate several components of the relationship between neuronal damage following developmental alcohol …

Mechanisms Of Innate Immune Regulation Of Dermonecrosis During Staphylococcus Aureus Skin Infections, Moriah J. Castleman

Biomedical Sciences ETDs

S. aureus is the dominant cause of skin and soft tissue infections (SSTIs) in humans. The importance of S. aureus as the primary cause of skin infections has increased exponentially over the last few decades since the emergence of resistance to β-lactam antibiotics. Furthermore, the rise of methicillin-resistant S. aureus (MRSA) strains has led to hospitals stays, increased financial burden and increased mortality. A significant proportion of MRSA infections have been attributed to community-acquired strains (CA-MRSA), specifically the USA300 isolates, which can cause deadly disease in otherwise healthy individuals. Due to the increase in antibiotic resistance and the lack of …

Trim28 Interacts With Ezh2 To Regulate Its Activity, Jing Li, Jing Li

Dissertations and Theses (Open Access)

In this dissertation, I discovered that TRIM28 interacts with EZH2 and regulates its activity in breast cancer cells. EZH2, the major H3K27 tri-methyltransferase, is over expressed in multiple subtypes of breast cancer; however, whether EZH2 plays an active role in breast cancer progression or treatment resistance is unknown. Here, we determined EZH2-interacting proteins in MCF7 cells by immunoprecipitation/mass spectrometry and detected TRIM28 with a high confidence score. TRIM28 is a transcription co-regulator with an N-terminal tri-partite RING finger, B-boxes and a coiled-coil domain (RBCC) and a C-terminal PHD/Bromo domain. Domain mapping revealed that the RBCC domain of TRIM28 interacts with …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations and Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

Plasmacytoid Dendritic Cell-Mediated Humoral Autoimmunity, Stephanie M. Dorta-Estremera Ph.D.

Dissertations and Theses (Open Access)

Humoral autoimmunity is characterized by the breakdown of B cell immune tolerance to self-antigens and consequent production of pathogenic autoantibodies. Plasmacytoid dendritic cells (pDCs), a potent type I interferon (IFN-I) producer, have been linked to the pathogenesis of systemic lupus erythematosus (SLE), a prototypic systemic humoral autoimmune disease. However, the cellular events that stimulate the development of humoral autoimmunity as a result of pDC activation have not been characterized. Moreover, the B cell subset(s) responsible for the generation of autoantibodies remains to be clearly identified.

The immunization of DNA-containing amyloids into non-autoimmune mice triggers the activation of pDCs and induction …

One Significant Step: How Reforms To Prison Districts Begin To Address Political Inequality, Erika L. Wood

University of Michigan Journal of Law Reform

Skyrocketing rates of incarceration over the last three decades have had profound and lasting effects on the political power and engagement of local communities throughout the United States. Aggressive enforcement practices and mandatory sentencing laws have an impact beyond the individuals who are arrested, convicted, and incarcerated. These policies have wide-ranging and enduring ripple effects throughout the communities that are most heavily impacted by criminal laws, predominantly urban and minority neighborhoods. Criminal justice policies broadly impact everything from voter turnout and engagement, to serving on juries, participating in popular protests, census data, and the way officials draw legislative districts. The …

ETSU Faculty Works

β-Glucans have beneficial health effects due to their immune modulatory properties. Oral administration of β-glucans affects tumour growth, microbial infection, sepsis, and wound healing. We hypothesized that pre-treatment with orally delivered soluble and particulate β-glucans could ameliorate the development of aggravate dextran sulfate sodium (DSS) induced intestinal inflammation. To study this, mice were orally pre-treated with β-glucans for 14 days. We tested curdlan (a particulate β-(1,3)-glucan), glucan phosphate (a soluble β-(1,3)-glucan), and zymosan (a particle made from Saccharomyces cerevisiae, which contains around 55% β-glucans). Weight loss, colon weight, and feces score did not differ between β-glucan and vehicle treated groups. …

Redefining Significance: Experiences Of Humanities Faculty Engaged In Undergraduate Research, Susan Mendoza

Dissertations

Programs that actively engage students in research and scholarship are the touchstone for integrating undergraduate education with authentic scholarly inquiry. Recent empirical studies demonstrate that undergraduate research experiences (URE) are related to increased student learning and development, increased levels of retention, increased enrollment in graduate school, and increased understanding of research as a vocation and profession. However, these seminal studies focus on URE in the STEM (science, technology, engineering, and math) disciplines. Although there are some studies that explore undergraduate research in the social sciences and humanities, the accepted models and best practices of undergraduate research are entrenched in the …

Computational Analysis Of The Sir Mathematical Model For The Dengue Fever, Joseph Phillip Diaz

Theses and Dissertations

Dengue fever is a disease affecting people in more than 100 countries. Here we consider a host and vector model for the transmission of dengue fever. This SIR model consists of three compartments of susceptible, infective and removed for host (human) and two compartments of susceptible and infective for vector (dengue mosquitos). These five compartments yield five coupled nonlinear ordinary differential equations (ODEs). After non-dimensionalization, we have a system of three nonlinear ODEs. Reproductive number and two equilibrium points are calculated for various cases. Simulation is carried out for susceptible, infective and removed and the results are presented in graphical …

The Transformative Experiences Of Female Educators As A Catalyst For Social Change In The World, April D. Jordan

Dissertations

As social justice issues become known, one may be moved to act in the hopes of alleviating the conditions that burden marginalized and oppressed people. What is sometimes missing from the discourse when discussing oppressive issues is the role women play in counteracting such subjugation. Also essential, yet missing from the research, are studies that underscore the importance of educators fostering social action change outside of and apart from institutions of learning and curriculum planning. This qualitative study examined the lives of six, nontraditional, female educator intellectuals whose perceptions of self (identity) and the world were transformed by engaging in …
