Epidermal Growth Factor Receptor (Egfr) Inhibition By Polychlorinated Biphenyls Contributes To Non-Alcoholic Fatty Liver Disease (Nafld)., Josiah Hardesty
Epidermal Growth Factor Receptor (Egfr) Inhibition By Polychlorinated Biphenyls Contributes To Non-Alcoholic Fatty Liver Disease (Nafld)., Josiah Hardesty
Electronic Theses and Dissertations
This dissertation describes how poly-chlorinated biphenyls (PCBs) exacerbate the pathogenesis of non-alcoholic fatty liver disease (NAFLD). While PCBs were banned in 1979, they still persist in contaminated biota, including food, and are detected in human plasma and adipose. The body burden of PCBs is associated with elevation of liver enzymes and necrosis markers in humans, characteristic of NAFLD. PCB exposure in high-fat diet fed mice leads to steatohepatitis that recapitulate the findings seen in exposed humans. The global estimate of people diagnosed with NAFLD is up to 1 in 4 people, unrelated to dietary or genetic factors. The hepatic mechanisms …
Nonalcoholic Fatty Liver Disease, Whitney Smith
Nonalcoholic Fatty Liver Disease, Whitney Smith
Nursing Student Class Projects (Formerly MSN)
Nonalcoholic fatty liver disease (NAFLD) is a common, chronic disease process that has historically affected adults but is becoming more common among children and adolescents due to rising rates of childhood obesity. While the primary risk factor for NAFLD is obesity, other metabolic conditions including dyslipidemias and insulin-resistance may also contribute to increased risk of NAFLD also. NAFLD occurs when excess triglycerides and free fatty acids (FFA) infiltrate the liver and are stored as lipids inside hepatocytes. In addition to the effects of decreased liver function from damaged cells, NAFLD also contributes to increased levels of inflammatory cytokines that further …

Loss Of Marv1 Promotes Chop Signaling In Mouse Liver, Shad Anthony Mitchell
Graduate School of Biomedical Sciences Theses and Dissertations
Metabolic syndrome (MetS) is a term used to define a set of metabolic diseases: obesity, type 2 diabetes (T2D), hyperlipidemia, hypertension, nonalcoholic fatty liver disease (NAFLD), and nonalcoholic hepatosteatosis (NASH). Those with MetS have a higher incidence of cardiovascular disease and stroke. Current drug treatments for MetS treat the individual pathologies associated with the diseases, rather than directly targeting MetS as a whole. We hypothesize that the inhibition of a ubiquitous lipid transporter known as ARV1 can improve pathologies associated with MetS. To test this hypothesis, we utilized liver tissue from mARV1 knockout mice fed a high-fat diet and examined …
Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane
Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane
Human Nutrition and Hospitality Management Undergraduate Honors Theses
Obesity prevalence in the United States continues to increase and is associated with health consequences such as type 2 diabetes, hypertension, atherosclerosis, and hyperlipidemia. Among many contributing factors to obesity, fructose may be one of the major reasons as it disrupts the antioxidant system thereby resulting in an accumulation of reactive oxidative species and leading to obese conditions. The enzyme, isocitrate dehydrogenase 2 (IDH2), reduces nicotinamide adenine dinucleotide phosphate from the TCA Cycle, hence might be implicated with not only energy metabolism but also cellular redox homeostasis. Therefore, the hypothesis was that IDH2 deficiency in mice would exacerbate hepatic lipid …

Background/objectives
CYP2A6 (CYP2A5 in mice) is mainly expressed in the liver. Hepatic CYP2A6 expression is increased in patients with non-alcoholic fatty liver disease (NAFLD). In mice, hepatic CYP2A5 is induced by high fat diet (HFD) feeding. Hepatic CYP2A5 is also increased in monosodium glutamate-induced obese mice. NAFLD is associated with obesity. In this study, we examined whether obesity is related to CYP2A6.
Subjects/methods
Obesity genetic association study: The SAGE is a comprehensive genome-wide association study (GWAS) with case subjects having a lifetime history of alcohol dependence and control subjects never addicted to alcohol. We used 1030 control individuals with self-reported …
