Metabolic Inflexibility in Skeletal Muscle With Obesity
(East Carolina University, 2009)The skeletal muscle of obese individuals has a reduced capacity to oxidize lipids. The hypothesis to be tested in this dissertation is that the ability to regulate lipid oxidation in response to lipid exposure is impaired ... -
Modulation of IKKβ with AMPK Improves Insulin Sensitivity in Skeletal Muscle
(East Carolina University, 2008-11)Activation of the insulin receptor substrate (IRS)-1 is necessary for proper transduction of the insulin signal. IRS-1 serine312(human)/307(rodent) phosphorylation, however, results in disruption of this signal and subsequent ... -
NADPH Oxidase as a Mechanistic Link Between Erectile Dysfunction, Peripheral, and Coronary Endothelial Dysfunction in Obesity
(East Carolina University, 2012)Cardiovascular complications involving both microvascular and macrovascular tissues are the major cause of morbidity and mortality in obese patients. Clinical and epidemiological studies suggest that erectile dysfunction ... -
NOVEL MECHANISMS GOVERNING SKELETAL MUSCLE MITOCHONDRIAL BIOENERGETICS : OXPHOS EFFICIENCY AND cAMP/PKA SIGNALING
(East Carolina University, 2014)Understanding the regulation of cellular metabolism is paramount to treating the growing prevalence of metabolic disease worldwide. In cellular metabolism, mitochondrial oxidative phosphorylation (OXPHOS) plays a key role ... -
Peroxisomal-Mitochondrial Metabolic Interactions in Lipid Metabolism in Human Skeletal Muscle
(East Carolina University, 2016-11-16)Peroxisomal activity and associated functions, including [beta]-oxidation contributions toward maintaining cellular lipid homeostasis, is poorly defined in extra hepatic tissues, most especially in human skeletal muscle ... -
The Physiological and Pathological Role of Mitochondrial Calcium in the Diabetic Heart
(East Carolina University, 2011)Diabetic patients are more susceptible to ischemia/reperfusion injury and cardiac dysfunction likely due alterations in mitochondrial calcium handling. The purpose of this work was to determine if redox-dependent changes ... -
Potential Mechanisms for Amelioration of Type 2 Diabetes Following Bariatric Surgery
(East Carolina University, 2011)Severe obesity and Type 2 Diabetes (T2DM) are worldwide health concerns reaching epidemic proportions. Roux-en-Y gastric bypass (RYGB) has been shown to elicit a rapid and durable improvement and/or remission of T2DM in ... -
The Region Specific Influence of Estradiol on In-Vivo Lipolysis in Subcutaneous Adipose Tissue in Overweight-to-Moderately-Obese Premenopausal Women
(East Carolina University, 2012)Premenopausal women demonstrate preferential accumulation of adiposity in the gynoid region, a distribution which shifts towards the abdominal region after the menopausal transition. Although estrogen is implicated as a ... -
Regulation of Lipolysis By Perilipin : influence of Obesity and Exercise Training
(East Carolina University, 2010)Obesity is the result of excess energy storage due to an imbalance between energy storage and energy utilization. Excess energy is stored as triacylglycerol (TAG) in adipose tissue in various regions throughout the body. ... -
SKELETAL MUSCLE LIPID PARTITIONING : CONSEQUENCES OF ALTERATIONS IN ACYL-COA SYNTHETASE-5 AND DIGLYCERIDE ACYLTRANFERASE-1 EXPRESSION
(East Carolina University, 2011)An oversupply of fatty acids and inadequacies in their partitioning toward oxidation and/or storage will lead to disruptions in cellular homeostasis. Reductions in mitochondrial content and lower rates of fatty acid ... -
SKELETAL MUSCLE METABOLIC FLEXIBILITY IMPAIRMENTS IN RESPONSE TO LIPID WITH OBESITY : EFFECT OF EXERCISE TRAINING
(East Carolina University, 2012)Obese individuals exhibit skeletal muscle metabolic inflexibility by failing to increase fat oxidation and genes linked with mitochondrial biogenesis in response to a high-fat diet (HFD) and lipid incubation in cell culture. ... -
Stiffness of Intrinsic Foot Structures in Diabetic Individuals and the Effect of Stiffness on Plantar Pressures During Gait
(East Carolina University, 2020-01-06)Plantar foot ulcers are a severe and common complication associated with diabetes that overwhelmingly lead to non-traumatic major amputations among diabetic individuals. There are several known factors that contribute to ... -
Unravelling the mechanisms of menopause-induced insulin resistance: novel roles for estradiol in skeletal muscle mitochondrial function
(East Carolina University, 2016-11-16)Menopause results in a progressive decline in ovarian production of 17[beta]-estradiol (E2), increased adiposity and a higher risk for type-2 diabetes, but hormone replacement therapies containing E2 reverse most of these ...
