Regulation Of Lipid Homeostasis, Inflammatory Signalling And Atherosclerosis By The Peroxisome Proliferator-Activated Receptor Delta, Lazar A. Bojic
Regulation Of Lipid Homeostasis, Inflammatory Signalling And Atherosclerosis By The Peroxisome Proliferator-Activated Receptor Delta, Lazar A. Bojic
Electronic Thesis and Dissertation Repository
The peroxisome proliferator-activated receptor (PPAR) δ is a ligand-dependent transcription factor that has been implicated in metabolic and inflammatory regulation. The molecular and physiological mechanisms by which PPARδ activation regulates lipid metabolism, inflammatory signaling and protection from atherosclerosis in states of metabolic disturbance such as insulin resistance and dyslipidemia, were investigated in a series of in vitro and in vivo studies. In vitro experiments demonstrated that PPARδ activation inhibits atherogenic lipoprotein-induced lipid accumulation and the associated proinflammatory responses. The primary mechanisms for these effects were increased fatty acid β-oxidation, decreased lipoprotein lipase (LPL) activity, reduced MAPK signaling and improved insulin …
Genetic Approaches To Studying Complex Human Disease, Joseph B. Dube
Genetic Approaches To Studying Complex Human Disease, Joseph B. Dube
Electronic Thesis and Dissertation Repository
Common, complex diseases such as cardiovascular disease (CVD) represent an intricate interaction between environmental and genetic factors and now account for the leading causes of mortality in western society. By investigating the genetic component of complex disease etiology, we have gained a better understanding of the biological pathways underlying complex disease and the heterogeneity of complex disease risk. However, the development of high throughput genomic technologies and large well-phenotyped multi-ethnic cohorts has opened the door towards more in-depth and trans-disciplinary approaches to studying the genetics of complex disease pathogenesis. Accordingly, we sought to investigate select complex traits and diseases using …
Oxidation Of Thrombomodulin Methionine 388 In Cigarette Smokers, Samrat B. Thapa
Oxidation Of Thrombomodulin Methionine 388 In Cigarette Smokers, Samrat B. Thapa
Graduate Theses and Dissertations
This work tested the hypothesis that oxidation of methionine 388 in thrombomodulin is higher in cigarette smokers, and thus a likely contributor towards the hypercoagulable state in smokers. Thrombomodulin, a protein cofactor found on endothelial cell surfaces, regulates the activity of thrombin. Thrombin bound to thrombomodulin no longer converts fibrinogen to fibrin, but instead activates Protein C which, in turn, stops the coagulation cascade by inactivation of clotting factors. The oxidation of methionine 388 of thrombomodulin has been shown in vitro to dramatically decrease the anticoagulant cofactor activity of thrombomodulin. The blood of cigarette smokers is more prone to clot …
