The Effects Of A High Fat Diet On Mitochondrial Biogenesis And Inflammation In The Brain., Lauren Suzanne Vervaecke Jan 2013

The Effects Of A High Fat Diet On Mitochondrial Biogenesis And Inflammation In The Brain., Lauren Suzanne Vervaecke

Theses and Dissertations

INTRO: High fat diets (HFD) ingested over long periods of time have been shown to cause diet induced obesity leading to excessive adiposity and chronic low grade inflammation. Here we have shown how differing levels of saturated fats (SF), which are common storage fats, affect markers of inflammation and mitochondrial biogenesis. IL-1รข and TNF-alpha are pro-inflammatory cytokines that have been shown to increase with a HFD, while molecular signalers, PGC-1alpha, cyt c, and SIRT1, related to mitochondrial biogenesis have been shown to decrease. Despite the risks of consuming a diet high in SF's, consumers continue to buy energy dense ...


An Investigation Into The Influence Of Dietary Saturated Fat And Quercetin Supplementation On Adiposity, Macrophage Behavior, Inflammation, And Non-Alcoholic Fatty-Liver Disease, Reilly Enos Jan 2013

An Investigation Into The Influence Of Dietary Saturated Fat And Quercetin Supplementation On Adiposity, Macrophage Behavior, Inflammation, And Non-Alcoholic Fatty-Liver Disease, Reilly Enos

Theses and Dissertations

The overall objective of this dissertation was to examine the degree to which manipulation of the saturated fat content of a high-fat diet influenced obesity-related outcomes as well as to see if the naturally-occurring flavonoid, quercetin, could attenuate the resulting obesity and related metabolic and inflammatory side effects. Specifically, these studies examined 1) the influential role of saturated fat on macrophage function, inflammation, and other obesity-related comorbidities, including non-alcoholic fatty-liver disease, and 2) the potential benefits of quercetin supplementation. Overall, results from these studies suggest that adiposity, macrophage behavior, inflammation, insulin resistance, and non-alcoholic fatty-liver disease progression can be greatly ...
