Reno-Protective And Immune Effects Of Growth Differentiation Factor 15 In Obesity-Related Kidney Disease, 2022 University of South Dakota
Reno-Protective And Immune Effects Of Growth Differentiation Factor 15 In Obesity-Related Kidney Disease, Jessie T. Sullivan
According to the World Health Organization, worldwide obesity has tripled since 1975 and is still on the rise, putting people at a higher risk of some cardiovascular diseases and kidney disease. Growth differentiation factor 15 (GDF15) is a stress-responsive cytokine that has been studied recently for its role in multiple biological processes and diseases. The member of the transforming growth factor beta (TGF-b) family has been investigated as a therapeutic agent and biomarker for obesity and associated cardiovascular diseases, stroke, diabetes, osteoarthritis, cancer, and kidney disease. Studies have shown the anti-inflammation, anti-obesity, and anti-diabetic effects of GDF15, but few have ...

Characterizing The Roles Of Cannabinoid Receptor 1 & 2 In Zebrafish Behavior, Metabolism, And Seizure-Induced Activity, Kayci Kimmons
Epileptic disorders like Dravet Syndrome require novel studies to determine the most ideal treatment. New research linking the endocannabinoid system (ECS) to epileptic disorders is arising, but there is still much to be discovered about the function and regulatory impact of the endocannabinoid system and its receptors in epilepsies like Dravet. In this study, knockout models of larval and adult zebrafish (Danio rerio) were used to investigate the roles of cannabinoid receptors 1 & 2 in behavior, brain mitochondrial metabolism, and seizure-induced activity following exposure to THC and CBD. Larval zebrafish which lacked cannabinoid receptor 1 exhibited increased locomotion compared to ...

Severe Hypoxia Up-Regulates Gluconeogenesis In Daphnia, 2022 East Tennessee State University
Severe Hypoxia Up-Regulates Gluconeogenesis In Daphnia, Morad C. Malek
Undergraduate Honors Theses
Hypoxia is a significant low oxygen state that has complex and diverse impacts on organisms. In aerobes, various adaptive responses to hypoxia are observed that vary depending on the level of oxygen depletion and previous adaptation, hence the continued attention to hypoxia as an important abiotic stressor. Adaptive responses to hypoxia are primarily governed by the hypoxia-inducible factors (HIFs), which activate downstream genetic pathways responsible for oxygen transport and metabolic plasticity. In aquatic habitats, oxygen availability can vary greatly over time and space. Therefore, aquatic organisms’ adaptation to hypoxia is likely pervasive, especially in genotypes originating from waterbodies prone to ...

Determining The Genomic Localization And Binding Partners Of Zinc Finger Protein 410, 2022 Liberty University
Determining The Genomic Localization And Binding Partners Of Zinc Finger Protein 410, Mariko Locke
Senior Honors Theses
The results of a folate deficiency study affecting cognition in mice suggested the altered genes may be controlled by a transcription factor known as Zinc Finger Protein 410 (Zfp410). Due to a lack of literature on Zfp410’s interacting proteins and DNA-binding location, our study aims to further elucidate the role Zfp410 plays in affecting cognition. A custom antibody was used to determine the Zfp410 isoforms present in mouse and rat brains. Moreover, the antibody was used to determine the binding partners of Zfp410 in the brain and locate specific genomic regions/sequences with which it associates in vivo. These ...

Dietary intakes play an important role in the development of metabolic complications during pregnancy. While reported observational studies reveal an inverse association of healthy diets with weight gain, gestational diabetes, and hypertensive complications during pregnancy, there is a paucity of studies conducted among women of specific ethnicities vulnerable to higher risks of pregnancy complications. This is a secondary cross sectional analysis using baseline data from a previously reported clinical trial. We aim to identify associations of maternal habitual dietary intakes with cardiometabolic risks and inflammatory profiles in primarily African American (AA) and Hispanic women in the first half of pregnancy ...

Obesity prevails worldwide to an increasing effect. For example, up to 42% of American adults are considered obese. Obese individuals are prone to a variety of complications of metabolic disorders including diabetes mellitus, hypertension, cardiovascular disease, and chronic kidney disease. Recent meta-analyses of clinical studies in patient cohorts in the ongoing coronavirus-disease 2019 (COVID-19) pandemic indicate that the presence of obesity and relevant disorders is linked to a more severe prognosis of COVID-19. Given the significance of obesity in COVID-19 progression, we provide a review of host metabolic and immune responses in the immunometabolic dysregulation exaggerated by obesity and the ...

Citrullination, the conversion of peptidyl-arginine into peptidyl-citrulline, is involved in the breakage of self-tolerance in anti-CCP-positive rheumatoid arthritis. This reaction is catalyzed by peptidyl arginine deiminases (PADs), of which PAD2 and PAD4 are thought to play key pathogenic roles. Small-molecule PAD inhibitors such as the pan-PAD inhibitor BB-Cl-amidine, the PAD2-specific inhibitor AFM-30a, and the PAD4-specific inhibitor GSK199 hold therapeutic potential and are useful tools in studies of citrullination. Using an ELISA based on the citrullination of fibrinogen, we found that AFM-30a inhibited the catalytic activity of PADs derived from live PMNs or lysed PBMCs and PMNs and of PADs in ...

Food for Health Papers & Publications
Stool descriptors have become popular due to the large diffusion of the Bristol Stool Form Scale (BSFS) via clinical studies, clinical trials, and social media. The applications have been numerous and centered around standardization of terminology that can be used by health care professionals and patients alike, as well as individuals interested in their wellness and the associated partners in the wellness industry. For a portion of the population, the digestive content is rerouted to an external manufactured pouch or bag, making the use of the BSFS visual descriptors of stool difficult. From day one post-resection surgery, ostomates are challenged ...
Understanding The Effect Of Dietary Palmitic Acid On Glycolysis During Innate Immune Memory In Macrophages, 2021 Portland State University
Understanding The Effect Of Dietary Palmitic Acid On Glycolysis During Innate Immune Memory In Macrophages, Khaleda A. Aqaei
University Honors Theses
Trained immunity is long-term innate immune memory induced by a primary stimulus, which leads to hyper-inflammation upon secondary stimulation with a homologous or heterologous ligand. Trained immunity is mediated by epigenetic and metabolic reprogramming of the target cell and leads to modification of gene expression and cellular function. Classically, trained immunity is initiated by β-glucans, an inflammatory molecule found on the exterior of fungal species. Interestingly, our lab has recently described that dietary fatty acids can initiate trained immunity, working through similar pathways as β-glucans. Specifically, our data show that a pre-treatment with a specific dietary saturated fatty acid (SFA ...

Investigating the relationships between protein function and fitness provides keys for understanding biochemical mechanisms that underly evolution. Mutations with partial fitness defects can delineate the threshold of biochemical function required for viability. We utilized a previous deep mutational scan of HIV-1 protease (PR) to identify variants with 15-45 per cent defects in replication and analysed the biochemical function of eight variants (L10M, L10S, V32C, V32I, A71V, A71S, Q92I, Q92N). We purified each variant and assessed the efficiency of peptide cleavage for three cut sites (MA-CA, TF-PR, and PR-RT) as well as gel-based analyses of processing of purified Gag. The cutting ...
Gestational Diabetes: What About Your Exercise?, 2021 Kennesaw State University
Gestational Diabetes: What About Your Exercise?, Andreana Henry
Symposium of Student Scholars
Previous research on exercise as a form of preventative care to reduce the risk of gestational diabetes has produced conflicting views. When and why exercise is the most beneficial during pregnancy has been widely debated, as well as which trimester exercise is the most effective to reduce the risk of gestational diabetes. It has been argued that if a woman has not previously incorporated exercise into her lifestyle, during pregnancy is not the ideal time to start. Conversely, light to moderate exercise is encouraged to decrease the chances of gestational diabetes, but which gestation period exercise will have the greatest ...

Changes in metabolism that affect mitochondrial and glycolytic networks are hallmarks of cancer, but their impact in disease is still elusive. Using global proteomics and ubiquitome screens, we now show that Parkin, an E3 ubiquitin ligase and key effector of mitophagy altered in Parkinson's disease, shuts off mitochondrial dynamics and inhibits the non-oxidative phase of the pentose phosphate pathway. This blocks tumor cell movements, creates metabolic and oxidative stress, and inhibits primary and metastatic tumor growth. Uniformly down-regulated in cancer patients, Parkin tumor suppression requires its E3 ligase function, is reversed by antioxidants, and is independent of mitophagy. These ...

Thermal Properties Of 18f-Fdg Uptake And Imaging In Positron Emission Tomography Scans Of Cancerous Cells, Carleigh R. Eagle
PANDION: The Osprey Journal of Research and Ideas
Positron Emission Tomography (PET) scans can utilize a radioactive tracer, in this case 2-deoxy2-[fluorine-18] fluoro-D-glucose (18F-FDG), to visualize malignant tumors in cancer patients. The uptake was compared to glucose to understand the difference in thermal properties, which contribute to the ability to image the cancerous cells. The uptake of 18F-FDG by cancer cells and the imaging process of positron emission tomography were reviewed from a thermodynamic perspective. Gastrointestinal and neurological imaging techniques were reviewed to understand the role of PET imaging in different areas of the human body.
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, 2021 Missouri State University
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
MSU Graduate Theses
Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological ...
