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 ...
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 ...
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. ...
ESTABLISHMENT OF THE PYRUVATE DEHYDROGENASE COMPLEX AS A CENTRAL REGULATOR OF MITOCHONDRIAL REDOX WITHIN SKELETAL MUSCLE
(East Carolina University, 2013)
Once regarded as "byproducts" of aerobic metabolism, the production of superoxide/H₂O₂ is now understood to be a highly specialized and extensively regulated process responsible for exerting control over a vast number of ...
