Quantitative Analysis Of The Impact Of Automatically Generated Normal Tissue Contours On Knowledge-Based Planning Model Quality, Samuel Christopher Baker Arnold

All ETDs from UAB

While radiotherapy has become one of the primary standards of treatment for cancer in areas such as the brain, treatment plans are limited by the time it takes physicians to contour CT images used for dose distribution calculations. Automation of the contouring process can not only improve the rate of plan formation but establish an improved standard of care. With the development and implementation of knowledge-based planning (KBP) in radiation oncology, information derived from treatment plans provide machine learning models with years of experience to assess and create future treatment plans. Since KBP model quality rely on contouring from training …


Crucial Role Of T Follicular Helper Cell-Derived Ifn-Γ In Lung Resident Memory B Cell Responses, Nicole Michelle Arroyo-Diaz Jan 2023

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 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. …

Novel Role For St6gal1 Sialyltransferase As A Tumor Driver In Pancreatic Ductal Adenocarcinoma, Nikita Umakant Bhalerao

All ETDs from UAB

ST6Gal1 sialyltransferase adds negatively charged sialic acid in an α2,6 linkage to N-glycans on glycoproteins bound for the cell surface/secretion thus altering receptor structure, function and downstream signaling pathways. ST6Gal1 is upregulated in multiple cancers, including pancreatic, and imparts cancer stem cell-like phenotype. Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy with a survival rate of ~10%. Acinar to ductal metaplasia (ADM), the tumor initiation stage of PDAC, occurs in response to insults like pancreatitis, when acinar cells dedifferentiate and form ductal-like cells with stem and ductal gene upregulation. These cells, on acquiring mutations such as in KRAS gene, can …

Towards Minimally Invasive Genetically Targeted Control Of Neural Activity Using X-Rays, Kelli Cannon Jan 2023

Towards Minimally Invasive Genetically Targeted Control Of Neural Activity Using X-Rays, Kelli Cannon

All ETDs from UAB

X-genetics aims to replace visible light stimulation in optogenetics with X-radiation, offering improved bone penetration, minimal scattering, and enhanced targeting capabilities. This eliminates the need for surgical optic fiber implantation, reducing invasiveness and minimizing off-target effects. Discovering a receptor protein sensitive to X-rays or their byproducts is pivotal for advancing X-genetics.Two genetically encoded X-ray receptors (GEXRs) were investigated for X-genetics application: rhodopsin, historically associated with X-ray responses, and LITE-1, an unexpected candidate. Rhodopsin, when expressed in human embryonic kidney (HEK293) cells, demonstrated robust cAMP decreases upon visible light stimulation but remained unresponsive to moderate and high-dose X-rays, suggesting it may …


Weight Loss And Physical Activity For People With Physical Disabilities, Julianne Clina Jan 2023

Weight Loss And Physical Activity For People With Physical Disabilities, Julianne Clina

All ETDs from UAB

People with physical disabilities (PWD) are at higher risk of obesity than people with-out physical disability (PWoD). For PWD, obesity presents a greater risk of secondary conditions; preventable medical, emotional, or social problems resulting directly or in-directly from an initial disabling condition. There is incomplete information about how disability-specific concerns influence obesity treatment and weight management, in part because PWD have typically not been included in this research. Additionally, while studies exist examining weight loss in PWD, a dearth of research exists examining weight loss maintenance for this population. Previously, weight control registries have been a valuable tool in gaining …

Role Of Proteoglycan Forms Of The Type Iii Tgf-Β Receptor/Betaglycan In Tgf-Β Signaling In Ovarian Cancer Models, Alex Kwon-Bowers Choi

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 …

Impact Of Exercise On Antioxidative-Stress Induced Endoplasmic Reticulum Dysfunction And Cardiac Remodelling, Arun Jyothidasan

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 …


The Critical Period Of Long-Term Plasticity In Adult-Born Granule Cells Is Mediated By T-Type Calcium Channels, William Michael Kennedy Jan 2023

The Critical Period Of Long-Term Plasticity In Adult-Born Granule Cells Is Mediated By T-Type Calcium Channels, William Michael Kennedy

All ETDs from UAB

Neurogenesis occurs in the dentate gyrus of adult rodents leading to a heterogeneous population of dentate granule cells (GCs) in the granule cell layer. Adult-born granule cells (abGCs) exhibit a transient period of elevated synaptic plasticity that contributes to their role in dentate gyrus function. Various mechanisms have been proposed to underlie the critical period of plasticity, including minimal GABAergic synaptic inhibition, robust NMDAR2B currents, and high intrinsic excitability conferred by T-type Ca2+ channels. In this collection of work, we investigate the critical period for long-term potentiation (LTP) in 4–6-week-old abGCs. We conclude that GABAergic inhibition regulates LTP in 4-week-old …

All ETDs from UAB

Lower respiratory infections are the primary cause of infectious death among the elderly. One reason for this is ‘inflamm-aging,’ a chronic low-grade inflammatory state that develops with advanced age. Pertinently, our group has shown increases in TNF levels to be responsible for age-dependent macrophage dysfunction (ADMD) and, in turn, enhanced susceptibility to Streptococcus pneumoniae, the leading cause of community-acquired pneumonia. The underlying molecular mechanisms responsible, however, remain unclear. Following adoptive transfer of alveolar macrophages (AM) from aged (18+ months) or young (3-6 month) mice into young mice, followed by infection with S. pneumoniae, we found that aged AM were sufficient …

Time-Restricted Feeding Attenuates Obesity-Induced Muscle Dysfunction Through Energy Metabolism And Microbiota Modulation, Christopher 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 …

Time-Restricted Feeding Modulates Dgat2 Expression In Cardiac And Skeletal Muscle, Yiming Guo Livelo

All ETDs from UAB

Circadian disruption caused by aging, genetic, environmental, and lifestyle factors can lead to compromised cardiac and skeletal muscle function and potentially accelerate the progression of metabolic diseases. Time-restricted feeding/eating (TRF/TRE, referred to as TRF hereafter), a dietary intervention that confines food intake within a consistent window of the day, has pleiotropic benefits from flies and mice to humans. However, the effectiveness of TRF on heart and muscle in the context of various metabolic challenges such as circadian disruption and obesity is largely unknown. Current insights into the mechanisms of TRF are primarily based on multi-omics approaches, particularly transcriptomes; however, limited …

Cd151+ T Cell Frequencies As An Immunological Clock That Identifies Premature Immunological Aging In People With Hiv, Mildred Perez

All ETDs from UAB

Antiretroviral therapy (ART) has greatly improved the life expectancy of People With HIV (PWH), but despite ART, PWH show signs of chronic immune hyperactivation (CIH), which results in the development of early-onset comorbidities, such as metabolic syndrome, diabetes, cardiovascular complications, neurodegenerative impairment, and can-cer. The underlying causes of CIH are, at best, incompletely understood, with suggested roles of microbial translocation, viral coinfections, T cell imbalances, and persistent HIV replication. Given that the CD4+ T cell population is most affected during acute HIV infec-tion, it is surprising that no T cell populations have been identified as drivers of CIH. Herein, we …
