Altered cell surface glycosylation is a hallmark of cancer; among aberrant glycan structures, hypersialylated proteins contribute to disease progression. The enzyme ST6 β-galactoside α2,6-sialyltransferase 1 (ST6GAL1) mediates α2,6-linked sialylation of N-glycosylated proteins and is upregulated in many cancers, including prostate cancer (PrCa). We propose that ST6GAL1 may be released by cancer cells in small extracellular vesicles (sEVs) in the PrCa tumor microenvironment to potentially modulate cell surface sialylation in recipient cells. We isolated sEVs from PrCa cells by density gradient separation and characterized them by nanoparticle tracking analysis using ZetaView and immunoblotting analysis. We identified ST6GAL1 in both its membrane-bound …

Stayin' Alive (Even Without Oxygen): Retinal Development In Austrofundulus Limnaeus, Carmen Zecilia Rodriguez

Dissertations and Theses

The vertebrate eye is one of the most metabolically active organs in the body and is particularly sensitive to environmental stressors such as oxygen deprivation. Understanding how eye development proceeds under such conditions can provide critical insights into mechanisms of cellular resilience, tissue organization, and developmental plasticity. The annual killifish Austrofundulus limnaeus represents a unique model for investigating these processes due to its remarkable tolerance to anoxia during embryogenesis. However, the wild-type form is heavily pigmented, limiting the effectiveness of traditional imaging techniques for studying eye development. This thesis characterizes eye development and anoxia resilience in both wild-type and melanin-deficient …

Performance Fatigability At Task Failure And Beyond: Distinct Patterns Of Recovery Following Constant Load Versus Intermittent Cycling Exercise, Zachary J. Mcclean, Keenan Macdougall, Matthew J. Jordan, Danilo Iannetta, Martin Macinnis, Saied J. Aboodarda

International Journal of Exercise Science

International Journal of Exercise Science 18(7): 971-983, 2025. The total work completed during an exercise session is often assumed to be the primary factor influencing the kinetics of post-exercise recovery. However, the duration of work and rest periods during high intensity interval training (HIIT) have been shown to impact the magnitude of physiological stress and could also impact post-exercise recovery. The aim of this study was to characterize the recovery time course of neuromuscular function following work-to-rest matched HIIT protocols with different work interval durations and conducted to task failure. Participants (n=12, n=6 females) completed a ramp incremental exercise test …

Human Adipose Stem Cell-Derived Small Extracellular Vesicles Modulate Glial Cell Response In Aged And Young Tbi Mouse Models, Salma S. Abdelmaboud

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is a leading cause of long-term neurological impairment, with aging significantly increasing vulnerability and worsening outcomes. Older individuals experience greater cognitive and motor deficits after TBI and often show diminished responses to therapeutic interventions. Both aging and TBI independently promote heightened neuroinflammation and cognitive dysfunction, increasing susceptibility to poor recovery. This study investigated the therapeutic potential of small extracellular vesicles (sEVs) derived from human adipose-derived stem cells (hASCs) to promote neurological recovery and modulate neuroinflammation in a mouse model of TBI. Male C57BL/6 mice aged 3, 15, and 20 months underwent controlled cortical impact (CCI) and …

Nadph Oxidase Isoforms (Nox-2 And Nox-4) In Myocardial Ischemia/Reperfusion Injury: Platelet Rich Plasma (Prp) As A Therapeutic Agent, Barbara Y. Hargrave, Frank Lattanzio

Cardiovascular Research Symposium

Introduction: Blood flow restoration to ischemic cardiac tissue is a critical and necessary intervention that has an associated downside: reperfusion injury. Reperfusion injury is a complicated process mediated in part by a pathological increase in reactive oxygen species (ROS). Although extremely elevated levels of ROS can cause cell damage, a minimum level of ROS is necessary for activation of Hydroxylated-HIF-1a (HIF-1a) and inhibition of Peroxisome Proliferator-Activated Receptor-alpha (PPARa) during myocardial ischemic reperfusion injury (MIRI). MIRI clinical manifestations include arrhythmias, myocardial stunning, decreased ventricular contractility and no-reflow. Platelet rich plasma (PRP) has improved left ventricular (LV) function after MIRI in …

Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Biophysical Effects Of Altered Myosin Binding Protein Stoichiometry In Atrial Myofilaments, Kelly N. Araujo

Dissertations

Cardiomyopathies, such as hypertrophic and dilated subtypes, are leading causes of heart failure and are often driven by genetic mutations that disrupt the structure and function of the cardiac sarcomere. While much of the research has focused on ventricular involvement, the role of atrial sarcomere dysfunction remains unexplored. The regulation of contractile function by sarcomeric proteins in the atria remains poorly understood, especially the impact of protein stoichiometry among myosin binding proteins. Cardiac myosin binding protein-C (cMyBP-C) and its atrial paralog, myosin binding protein H-like (MyBP-HL), have been shown to have a stoichiometric relationship within the atrial sarcomere. These two …

Asymmetric Fgf Receptor Dimerization: Implications For Fgf23 Biology And Drug Discovery, Mohammed S. Razzaque, Moosa Mohammadi

School of Medicine Publications

Fibroblast growth factor 23 (FGF23) requires both αKlotho and heparan sulfate proteoglycans (HSPGs) as obligatory coreceptors to bind, dimerize, and activate its FGF receptors (FGFRs) in the kidney, thereby regulating mineral ion and vitamin D homeostasis. Cryogenic electron microscopy studies reveal that FGF23 signaling proceeds through an asymmetric 1:2:1:1 FGF23–FGFR–αKlotho–HS assembly. According to this structural model, αKlotho simultaneously anchors FGF23 and one FGFR chain, referred to as the primary receptor (FGFRP), to form a 1:1:1 FGF23-FGFRP-αKlotho triplex, which boosts FGF23-FGFRP interaction. Subsequently, the HS coreceptor aids the triplex in recruiting a second FGFR chain, or secondary receptor (FGFRS), leading to …

Effects Of Body Armor On Respiratory Muscle Fatigue And Muscle Blood Flow During Progressive Treadmill Marching, Kathryn Bell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Torso-borne loads such as body armor are essential for modern military operations but impose mechanical and metabolic strain. These physiological stressors can trigger the inspiratory metaboreflex, which redirects blood flow from locomotor to respiratory muscles, further reducing muscle oxygen and endurance. While aerobic fitness has been shown to alleviate these effects, the interaction between sex, aerobic capacity, and oxygenation under load is not well understood. This study examined the physiological effects of torso-borne load carriage on respiratory muscle fatigue, skeletal muscle oxygenation, and exercise performance to volitional exhaustion and the degree to which sex and aerobic capacity influence these …

An Analysis Of The Influence Of Human Disease Pathogens On Core Behaviors Of The Black-Legged Tick, Emily F. Marinko

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ixodes scapularis, the black-legged or deer tick, is a vector for several different disease-causing microbes, including the causative agent of Lyme disease. As such, it is a major health concern for people living within its range in the eastern half of the United States, a habitation area that is increasing due to climate change. Despite its medical relevance as a disease vector, there is still much to learn about the basic behavior of these arachnids in the wild. Thus, the major hypothesis of this thesis is that ticks that are infected with specific human disease-causing microbes behave differently than those …
