Linking energy state to redox environment through mitochondrial redox circuits
(East Carolina University, 2016-11-16)Mitochondria are the primary producers of intracellular H2O2, an oxidant signaling molecule that has gained attention for its role in normal physiological processes and disease etiologies such as skeletal muscle insulin ... -
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 ... -
MuRF1 activity is present in cardiac mitochondria and regulates reactive oxygen species production in vivo
(2014-06)MuRF1 is a previously reported ubiquitin-ligase found in striated muscle that targets troponin I and myosin heavy chain for degradation. While MuRF1 has been reported to interact with mitochondrial substrates in yeast ... -
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 ... -
Novel role for thioredoxin reductase-2 in mitochondrial redox adaptations to obesogenic diet and exercise in heart and skeletal muscle
(2013)Increased fatty acid availability and oxidative stress are physiological consequences of exercise (Ex) and a high-fat, high-sugar (HFHS) diet. Despite these similarities, the global effects of Ex are beneficial, whereas ... -
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 ... -
The role of cardiac mitochondria in myocardial ischemia/reperfusion injury
(East Carolina University, 2012)Cardiovascular disease (CVD) exerts economic and humanitarian costs that are unparalleled by any other disease. Of the many etiologies of CVD, myocardial infarction accounts for over 50% of the associated mortality and ... -
The Role of Mitochondrial Biogenesis in Human Mesenchymal Stem Cell Differentiation and Acquisition of a Cardiac Phenotype
(East Carolina University, 2013)Introduction: With an increased understanding of myocardial infarction, human mesenchymal stem cell (hMSC) transplantation therapies have shown promising results as a possible treatment for heart failure. However, little ... -
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. ... -
Statin Therapy and Its Impact on Muscle Mitochondrial Function
(East Carolina University, 2021-05-28)In the United States there are more than 40 million Americans that treat or prevent hyperlipidemia and cardiovascular disease (CVD) through the use of statins. There is now a growing out opinion that there should be a more ... -
Targeting the mitochondrial inner membrane to improve bioenergetics in the diseased heart
(East Carolina University, 2014)Cardiovascular diseases continue to exact unparalleled economic and humanitarian costs across the globe. Manifestations of cardiovascular diseases include acute coronary syndromes and heart failure, both of which are ... -
The Influence of Diet-Induced Obesity and N-3 Fatty Acids on the Cardiac Mitochondrial Phospholipidome and Respiratory Activity
(East Carolina University, 2017-08-16)Cardiac mitochondrial phospholipids, notably cardiolipin (CL), regulate inner mitochondrial membrane (IMM) organization and protein function, particularly the enzymes associated with respiration. In a range of metabolic ... -
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 ...
