Aneuploidy disrupts cellular homeostasis. However, the molecular mechanisms underlying the physiological responses and adaptation to aneuploidy are not well understood. Deciphering these mechanisms is important because aneuploidy is associated with diseases, including intellectual disability and cancer. Although tumors and mammalian aneuploid cells, including several cancer cell lines, show altered levels of sphingolipids, the role of sphingolipids in aneuploidy remains unknown. Here, we show that ceramides and long-chain bases, sphingolipid molecules that slow proliferation and promote survival, are increased by aneuploidy. Sphingolipid levels are tightly linked to serine synthesis, and inhibiting either serine or sphingolipid synthesis can specifically impair the fitness …
Macrophage Migration Inhibitory Factor Mediates Protease-Activated Receptor 4-Induced Bladder Pain Through Urothelial High Mobility Group Box 1, Fei Ma, Dimitrios E. Kouzoukas, Katherine L. Meyer-Siegler, David E. Hunt, Lin Leng, Richard Bucala, Pedro L. Vera
Macrophage Migration Inhibitory Factor Mediates Protease-Activated Receptor 4-Induced Bladder Pain Through Urothelial High Mobility Group Box 1, Fei Ma, Dimitrios E. Kouzoukas, Katherine L. Meyer-Siegler, David E. Hunt, Lin Leng, Richard Bucala, Pedro L. Vera
Physiology Faculty Publications
Macrophage migration inhibitory factor (MIF) mediates pain although the mechanisms are not well understood. Urothelial activation of protease activated receptor 4 (PAR4) results in urothelial MIF release, urothelial high mobility group box 1 (HMGB1) release and bladder pain in mice without bladder inflammation. All three effects are prevented by MIF inhibition while intravesical disulfide HMGB1 alone can induce bladder pain. This study utilizes genetic MIF deletion to determine whether MIF mediates PAR4-induced bladder pain and is upstream of HMGB1-induced bladder pain. Wild type (C57/BL6) and MIF knockout (KO) mice were treated with intravesical PAR4 activating peptide or disulfide HMGB1 and …

Sestrins (1, 2, 3) are a family of stress-inducible proteins capable of attenuating oxidative stress, regulating metabolism, and stimulating autophagy. Sequestosome1 (p62) is also a stress-inducible multifunctional protein acting as a signaling hub for oxidative stress and selective autophagy. It is unclear whether Sestrin and p62Ser403 are regulated acutely or chronically by resistance exercise (RE) or training (RT) in human skeletal muscle. Therefore, the acute and chronic effects of RE on Sestrin and p62 in human skeletal muscle were examined through two studies. In Study 1, nine active men (22.1 ± 2.2 years) performed a bout of single-leg strength …

Organizational Effects Of Defeminizing Toxicants: Lessons Learned From An Environmental Sentinel Organism, The Fathead Minnow., Jonathan Ali
Organizational Effects Of Defeminizing Toxicants: Lessons Learned From An Environmental Sentinel Organism, The Fathead Minnow., Jonathan Ali
Theses & Dissertations
Endocrine disrupting compounds (EDCs) are chemicals that interfere with hormone function and are increasingly detected in aquatic environments, where they elicit adverse effects from exposed organisms. The toxicological effects of EDCs can be described as either activational (reversible) or organizational (irreversible), where the latter are associated with adverse outcomes in reproductive performance of adult fish. However, few studies have investigated the organizational impacts of anti-estrogenic or “defeminizing” EDCs, e.g. agrichemicals or pharmacological agents, in an environmentally-relevant or “sentinel” species. The objective of this study was to investigate the impacts of early-life EDC-initiated changes in estrogenic gene expression on organizational effects …
Response Of Appetite And Appetite Regulating Hormones To Acute Hypoxia, Morgan Busboom, Robert Shute, Dustin Slivka
Response Of Appetite And Appetite Regulating Hormones To Acute Hypoxia, Morgan Busboom, Robert Shute, Dustin Slivka
Journal of Human Performance in Extreme Environments
AIM: To determine the acute response of appetite and appetite regulating hormones after exposure to simulated altitude. METHODS: Seven males and five females (height: 178.9 ± 2.3 cm; weight: 77.3 ± 7.2 kg; body fat: 18.4 ± 1.7%) participated in two, three-hour trials in a hypoxic (5000 m) and normoxic (350 m) environment. Blood samples were collected prior to and immediately following three hours of exposure for the measurement of leptin, adiponectin, and acylated ghrelin. Appetite, acute mountain sickness, heart rate, blood oxygenation, tissue oxygenation, respiration rate, and whole body gases were also measured. RESULTS: Leptin was not different between …
Regulation Of Liver Mitochondrial Metabolism During Hibernation By Post-Translational Modification, Katherine E. Mathers
Regulation Of Liver Mitochondrial Metabolism During Hibernation By Post-Translational Modification, Katherine E. Mathers
Electronic Thesis and Dissertation Repository
Hibernation, characterized by a seasonal reduction in metabolism and body temperature, allows animals to conserve energy when environmental conditions (e.g. temperature, food availability) are unfavourable. During hibernation, small mammals such as the 13-lined ground squirrel (Ictidomys tridecemlineatus) cycle between two distinct metabolic states: torpor, where metabolic rate is suppressed by >95% and body temperature falls to ~5 °C, and interbout euthermia (IBE), where metabolic rate and body temperature rapidly increase and are maintained at euthermic levels several hours. Suppression of metabolism during entrance into torpor is paralleled by rapid suppression of liver mitochondrial metabolism. In my thesis, I …
Cholesterol Regulation Of Pulmonary Endothelial Calcium Entry Following Chronic Hypoxia, Bojun Zhang
Cholesterol Regulation Of Pulmonary Endothelial Calcium Entry Following Chronic Hypoxia, Bojun Zhang
Biomedical Sciences ETDs
Chronic hypoxia (CH)-induced pulmonary hypertension (PH) is associated with diminished ATP-induced endothelial Ca2+ entry as well as membrane cholesterol in pulmonary arteries. Store-operated Ca2+ entry (SOCE) and depolarization-induced Ca2+ entry are major components of the response to ATP and are similarly decreased after CH. Because endothelium-dependent vasodilation is closely associated with pulmonary endothelial [Ca2+]i, the blunted agonist-induced Ca2+ influx in pulmonary artery endothelial cells (PAEC) may contribute to the development of CH-induced PH. Interestingly, impaired agonist-induced Ca2+ influx in PAEC following CH can be restored by membrane cholesterol supplementation. In the current studies, we hypothesized that impaired Ca2+ entry in …

Methylglyoxal Requires Ac1 And Trpa1 To Produce Pain And Spinal Neuron Activation, Ryan B. Griggs, Don E. Laird, Renee R. Donahue, Weisi Fu, Bradley K. Taylor
Physiology Faculty Publications
Methylglyoxal (MG) is a metabolite of glucose that may contribute to peripheral neuropathy and pain in diabetic patients. MG increases intracellular calcium in sensory neurons and produces behavioral nociception via the cation channel transient receptor potential ankyrin 1 (TRPA1). However, rigorous characterization of an animal model of methylglyoxal-evoked pain is needed, including testing whether methylglyoxal promotes negative pain affect. Furthermore, it remains unknown whether methylglyoxal is sufficient to activate neurons in the spinal cord dorsal horn, whether this requires TRPA1, and if the calcium-sensitive adenylyl cyclase 1 isoform (AC1) contributes to MG-evoked pain. We administered intraplantar methylglyoxal and then evaluated …

High plasma levels of homocysteine, termed hyperhomocysteinemia, are a risk factor for vascular cognitive impairment and dementia, which is the second leading cause of dementia. While hyperhomocysteinemia induces microhemorrhages and cognitive decline in mice, the specific effect of hyperhomocysteinemia on each cell type remains unknown. We took separate cultures of astrocytes, microglia, endothelial cells, and neuronal cells and treated each with moderate levels of homocysteine for 24, 48, 72, and 96 hr. We then determined the gene expression changes for cell-specific markers and neuroinflammatory markers including the matrix metalloproteinase 9 system. Astrocytes had decreased levels of several astrocytic end feet …

Pharmacology and Physiology Faculty Publications
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by social deficits and repetitive/restrictive interests. ASD is associated with multiple comorbidities, including intellectual disability, anxiety, and epilepsy. Evidence that ASD is highly heritable has spurred major efforts to unravel its genetics, revealing possible contributions from hundreds of genes through rare and common variation and through copy-number changes. In this perspective, we provide an overview of the current state of ASD genetics and of how genetic research has spurred the development of in vivo and in vitro models using animals and patient cells to evaluate the impact of genetic mutations …
Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield
Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield
Electronic Theses and Dissertations
Sympathetic stimulation occurs in the heart after injuries such as ischemia/reperfusion (I/R) and myocardial infarction and affects myocardial remodeling. Prolonged sympathetic stimulation can result in myocardial dysfunction through its effects on cardiac myocyte apoptosis and myocardial fibrosis. Ubiquitin (UB) is well known for its role of tagging old or damaged proteins for degradation via the UB-proteosome pathway. The role of exogenous UB however, is not fully understood. Previously, our lab showed that β-adrenergic receptor (β-AR) stimulation increased levels of extracellular UB in the conditioned media of adult rat ventricular myocytes and that UB inhibits β-AR-stimulated apoptosis. This study investigates the …

Tumor necrosis factor alpha (TNFα) plays a significant role in the pathogenesis of airway inflammatory diseases. Inhalation of aerosolized TNFα induced airway hyperresponsiveness accompanied by airway inflammation in healthy human subjects, but the underlying mechanism is not fully understood. We recently reported a series of studies aimed to investigate if TNFα elevates the sensitivity of vagal bronchopulmonary sensory nerves in a mouse model; these studies are summarized in this mini-review. Our results showed that intratracheal instillation of TNFα induced pronounced airway inflammation 24 hours later, as illustrated by infiltration of eosinophils and neutrophils and the release of inflammatory mediators and …

Effects Of Temperature On Growth And Molting In Blue Crabs (Callinectes Sapidus) And Lesser Blue Crabs (Callinectes Similis), Abigail Ann Kuhn
Master's Theses
Temperature can exert impacts on many processes in ectotherms. With global temperatures rising due to climate change, many ectothermic species may exhibit changes in growth rates and size at maturity, and these changes can have population-level effects. Predicting responses of species to climate change will require not only knowledge of thermal tolerance limits, but also effects of temperature change on growth rates and other life history parameters. For arthropods that exhibit discontinuous growth (i.e., molting), this includes both intermolt period and growth per molt. Previous laboratory and field experiments suggest that temperature affects both intermolt period (IMP) and growth per …
Combined Effects Of Dissolved Oxygen And Temperature On Aerobic Respiration And Respiratory Recovery Responses Of The Spioniform Polychaete, Streblospio Gynobranchiata, In Relation To Body Size, Alyssa Bennett
Master's Theses
Elevated surface temperatures exacerbate the threat of hypoxia within coastal ecosystems. These two primary stressors likely interact as they elicit opposing physiological responses from marine organisms. Metabolic depression is typically associated with hypoxia, while metabolic rates increase with temperature. Moreover, physiological effects of combined stressors may not be additive. In light of increasing pressures from hypoxia, elevated ocean temperatures, and other stressors within coastal regions, studies need to examine effects of multiple stressors on physiology of coastal organisms.
Mass-specific aerobic respiration (VO2) was characterized as a proxy for metabolic cost of Streblospio gynobranchiata, at combined levels of …
The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey
The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey
Senior Theses
Type 1 Diabetics have various ways of managing their diabetes that have been studied for their effectiveness. Pregnancy in the Type 1 Diabetic has been understudied. It is known that Diabetics in general have poorer pregnancy outcomes because of poor glycemic control. This coupled with the fact that the body needs 3-4 times more insulin as pregnancy comes to an end makes managing blood glucose levels challenging for diabetics (Lowdermilk, 2016, p. 689). For the Type 1 Diabetic, there are two main ways to control diabetes: multiple daily injections using at least two type of insulin and continuous subcutaneous insulin …
Cellular Mechanisms Of Ionoregulation In The Gill Of Japanese Medaka And Rainbow Trout, Rebecca Jo Bollinger
Cellular Mechanisms Of Ionoregulation In The Gill Of Japanese Medaka And Rainbow Trout, Rebecca Jo Bollinger
Graduate Theses and Dissertations
Euryhaline fishes are capable of adapting to a wide range of salinities such as freshwater, brackish water or seawater. Through the combined effort of the gill, kidney and intestine, they are able to osmoregulate to maintain a constant internal hydromineral balance. As the gill is in direct contact with the external environment, it is continuously working to maintain ion and acid/base balance, gas exchange and eliminate nitrogenous waste. Fish in freshwater are subjected to osmotic water gain and diffusional ion loss across the gill and experience the opposite in seawater. Therefore, the gill exhibits extreme plasticity when experiencing a change …

UNLV Theses, Dissertations, Professional Papers, and Capstones
A large body of research links testosterone and cortisol responses to competition during adulthood. Little psychoneuroendocrine research has explored salivary steroid hormone responses to competition during middle childhood. This project investigated the relationship between acute salivary steroid hormone change, performance, competitor type, and outcome effects in three different field studies, while controlling for Body Mass Index (BMI) and pubertal development, in a population of ethnically Chinese, Hong Kong juvenile children, 8-11 years of age. The relative dynamics of salivary steroid change were assessed during a 1) coalitional physical competition (soccer) in boys, 2) a non-physical mixed-sex coalitional competition (math contest), …
Dietary Intake And Energy Expenditure Of Pararescuemen During Routine Training, Andrea Woita
Dietary Intake And Energy Expenditure Of Pararescuemen During Routine Training, Andrea Woita
UNLV Theses, Dissertations, Professional Papers, and Capstones
Pararescuemen are one group of Air Force Special Operations Forces (SOF) who engage in vigorous physical training to achieve mission readiness. This type of training requires high energy expenditures and matching dietary intake to support basic physiological needs and to meet performance demands. However, few studies have investigated the energy expenditure and dietary intake of SOF and none have specifically examined these behaviors in Pararescuemen. The goal of this investigation was to determine the energy expenditure and dietary intake of Pararescuemen during routine training - a period when these operators receive supervision and guidance for performance improvements, recovery, and career …

The Effects Of Selection For High Voluntary Wheel-Running Behavior On Nutrient Canal Abundance And Size, Nicolas Lawrence Schwartz
The Effects Of Selection For High Voluntary Wheel-Running Behavior On Nutrient Canal Abundance And Size, Nicolas Lawrence Schwartz
Electronic Theses, Projects, and Dissertations
Variations in skeletal morphology have often been used to interpret an organism’s overall activity level when direct observation is not possible. Although skeletal change in response to exercise is well documented, the skeleton’s response to mechanical loading is modulated by several factors (e.g. age, hormones, sex). Additionally, variation in skeletal morphology is partially a result of genetic variation, which is rarely accounted for in inferences of locomotor activity from skeletal remains. However, blood flow to long bones serves as a proxy for bone metabolic activity, which can be used to infer locomotor activity. Long bones receive blood from three sources, …
Insights Into The Therapeutic Potential Of Salt Inducible Kinase 1: A Novel Mechanism Of Metabolic Control, Randi Fitzgibbon
Insights Into The Therapeutic Potential Of Salt Inducible Kinase 1: A Novel Mechanism Of Metabolic Control, Randi Fitzgibbon
Dissertations & Theses (Open Access)
Salt inducible kinase 1 (SIK1) has been considered a stress-inducible kinase since it was first cloned in 1999. Continued efforts since this time have been dedicated to characterizing the structure and function of SIK1. Such research has laid the ground work for our understanding of SIK1 action and regulation in tissue and stimuli dependent manners. The fundamental findings of this dissertation continue in this tradition and include investigations of SIK1 regulatory mechanisms in skeletal muscle cells, the cellular and physiological effects of SIK1 loss of function in vitro and in vivo, and intracellular metabolic and mitochondrial regulation by this …

Complement 3a Receptor In Dorsal Horn Microglia Mediates Pronociceptive Neuropeptide Signaling, Suzanne Doolen, Jennifer Cook, Maureen Riedl, Kelley Kitto, Shinichi Kohsaka, Christopher N. Honda, Carolyn A. Fairbanks, Bradley K. Taylor, Lucy Vulchanova
Physiology Faculty Publications
The complement 3a receptor (C3aR1) participates in microglial signaling under pathological conditions and was recently shown to be activated by the neuropeptide TLQP‐21. We previously demonstrated that TLQP‐21 elicits hyperalgesia and contributes to nerve injury‐induced hypersensitivity through an unknown mechanism in the spinal cord. Here we determined that this mechanism requires C3aR1 and that microglia are the cellular target for TLQP‐21. We propose a novel neuroimmune signaling pathway involving TLQP‐21‐induced activation of microglial C3aR1 that then contributes to spinal neuroplasticity and neuropathic pain. This unique dual‐ligand activation of C3aR1 by a neuropeptide (TLQP‐21) and an immune mediator (C3a) represents a …

The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio
The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio
International Journal of Exercise Science
International Journal of Exercise Science 10(8): 1275-1296, 2017. Compared to investigations on hypocaloric diets, the effects of chronic overfeeding have been less studied. It has been posited that consuming calories in excess of daily caloric requirements will result in a gain in body weight and in particular fat mass regardless of which macronutrient(s) are consumed. However, recent evidence suggests that there is a quantitative difference in protein versus carbohydrate and/or fat overfeeding as it relates to body composition. Protein overfeeding or the consumption of a high protein diet may not result in a gain in body weight or fat mass …
