Attenuation Of Obesity, Hepatic Steatosis And Reversal Of Atherosclerosis By The Flavonoids Naringenin And Nobiletin, Amy C. Burke

Electronic Thesis and Dissertation Repository

Naringenin and nobiletin are naturally-derived citrus flavonoids that have significant lipid-lowering and insulin sensitizing effects in vitro and in vivo. In murine models of obesity, metabolic dysfunction and atherogenesis, these flavonoids protect against the development of cardiometabolic disease. However, the ability of naringenin and nobiletin to reverse existing metabolic dysfunction and atherosclerosis has not been investigated.

The purpose of this thesis was to investigate the ability of the citrus flavonoids, naringenin and nobiletin, to reverse obesity, metabolic syndrome and atherosclerosis in two different mouse models of atherosclerosis regression. The first chapter demonstrates in Ldlr^-/- mice with diet-induced obesity, …

Knockdown Of Heparan Sulfate Via Ndst1 Knockout Does Not Inhibit Mouse Aortic Endothelial Cell Alignment In-Vivo, John Diaz De Leon Iii

Dissertations and Theses

Atherosclerotic plaque localizes in predictable areas such as arches and bifurcations which are characterized by disturbed flow patterns and the resulting damage and dysfunction to the endothelium. Endothelial cells (ECs) under sustained laminar flow align in the direction of flow; however, under disturbed flow conditions, ECs sustain damage to their glycocalyx (GCX) which results in unaligned and rounder cells. An investigation into the role of NDST1 sulfation of heparan sulfate (HS), a key component of many proteoglycans which make up the GCX, was conducted. The descending aortas (DAs) of transgenic mice with conditional knockouts (KOs) of NDST1 in vascular ECs …
