Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
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 …

It has become increasingly evident that a high percentage of patients that recover from acute COVID-19 infection continue to suffer from a variety of persistent symptoms even months after viral clearance, the most common ones being fatigue, dyspnea, anosmia, dysgeusia, cognitive dysfunction, and psychological problems, including anxiety and depression. This syndrome, known as Post-acute sequelae of COVID-19 (PASC), can severely affect the life quality and represents an important health care concern. The exact causes for the symptoms observed in patients with PASC remain to be adequately characterized, but are likely to be associated with multiple factors, including residual disease and/or …
Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone
Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone
UNF Graduate Theses and Dissertations
Purpose Examine the relationships between high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and soluble tumor necrosis factor-α receptor-1 (sTNF-R1) and the cumulative risk of heart failure with reduced (HFrEF) and preserved (HFpEF) ejection fractions in a diverse, population-based sample. Methods Study sample included 6,814 adult (45-84 years of age) men and women who participated in the Multi-Ethnic Study of Atherosclerosis and were free of cardiovascular disease at baseline. Cox regression was used to calculate the hazard ratios (HR) associated with elevated baseline hs-CRP (> 3-10 mg/L), IL-6 (> 75th percentile) and sTNF-R1 (> 75th percentile) and risk of overall …

Endothelial nitric oxide (NO) synthase (eNOS) plays a critical role in the maintenance of blood vessel homeostasis. Recent findings suggest that cytoskeletal dynamics play an essential role in regulating eNOS expression and activation. Here, we sought to test whether modulation of cytoskeletal dynamics through pharmacological regulation of histone deacetylase 6 (HDAC6)-mediated tubulin deacetylation affects eNOS expression and endothelial function in vitro and in vivo.Wefound that tubulin acetylation inducer (tubacin), a compound that appears to selectively inhibit HDAC6 activity, dramatically increased eNOS expression in several different endothelial cell lines, as determined by both immunoblotting and NO production assays. Mechanistically, we found …

The goals of this study were to investigate the relationship of systemic and local cytokine responses with time to clinical stability (TCS) in patients with community-acquired pneumonia (CAP) and to develop a model to integrate multiple cytokine data into “cytokine response profiles” based on local vs. systemic and pro- vs. anti-inflammatory cytokine patterns in order to better understand their relationships with measures of CAP severity and outcomes. Forty hospitalized patients enrolled through the Community Acquired Pneumonia Inflammatory Study Group (CAPISG) were analyzed. Based on the ranked distribution of the levels of eight different pro-inflammatory cytokines and chemokines (IL-1b, IL-6, IL-8, …
Characterization Of The Role Of Insulin-Like Growth Factor Binding Protein 7 (Igfbp7) Using A Genetic Knockout Mouse Model, Maaged A. Akiel
Characterization Of The Role Of Insulin-Like Growth Factor Binding Protein 7 (Igfbp7) Using A Genetic Knockout Mouse Model, Maaged A. Akiel
Theses and Dissertations
In the US, the incidence and mortality rates of hepatocellular carcinoma (HCC) are alarmingly increasing since no effective therapy is available for the advanced disease. Activation of IGF signaling is a major oncogenic event in diverse cancers, including HCC. Insulin-like growth factor binding protein-7 (IGFBP7) inhibits IGF signaling by binding to IGF-1 receptor (IGF-1R) and functions as a potential tumor suppressor for hepatocellular carcinoma (HCC). IGFBP7 abrogates tumors by inducing cancer-specific senescence and apoptosis and inhibiting angiogenesis. We now document that Igfbp7 knockout (Igfbp7-/- ) mouse shows constitutive activation of IGF signaling, presents with pro-inflammatory and immunosuppressive microenvironment, and develops …

The median survival for idiopathic pulmonary fibrosis (IPF) patients from diagnosis is a dismal 3 years. This condition is characterized by pulmonary fibroproliferation and excess production and disordered deposition of extracellular matrix (ECM) proteins resulting in obliteration of the original tissue architecture, loss of lung function and eventual death due to respiratory failure. The main hindrance to the development of effective treatments against pulmonary fibrosis is the late detection of its progression and is often of unknown cause. Tobacco smoke represents the most important environmental factor linked to the development of pulmonary fibrosis, with over 60% of IPF patients current …
