The Biochemical Characterization Of Neuronal K+ Channel N-Glycans And Their Role In Regulating K+ Channel Function
Cartwright, Tara A. (East Carolina University, 2009)The Kv3 and Kv1 subfamilies of voltage–gated K+ channels are critical components which contribute to action potential repolarization throughout the central nervous system. Here, it was shown that both absolutely conserved ... -
DISCRIMINATING BETWEEN CARDIOLIPIN CONCENTRATION AND ACYL CHAIN COMPOSITION ON MEMBRANE BIOPHYSICAL ORGANIZATION
Pennington, Edward Ross (East Carolina University, 2018-11-28)The pathogenesis of cardiovascular diseases (CVDs) is driven, in part, from impairment in myocardial energy metabolism. There is convincing evidence that myocardial metabolic abnormalities are fundamentally driven by ... -
The Distribution Of Regulated Actomyosin States Is Central To Cardiac Muscle Regulation And Disturbance Of This Distribution Leads To Congenital Cardiomyopathies
Mathur, Mohit C. (East Carolina University, 2009)Hypertrophic and restrictive cardiomyopathies are congenital cardiac diseases that have an incidence of over one in five hundred and may lead to sudden cardiac death. One of the main impediments to directed treatment is ... -
Docosahexaenoic acid-derived metabolites target the B-cell driven immune response in obese mice
Crouch, Miranda Jill (East Carolina University, 2019-06-07)Obesity is associated with an impaired humoral immune response. As B cells mediate the humoral immune response, they are major cellular targets in diet induced obesity models. Several studies have established that B cell ... -
Effects of Exogenous and Autocrine Growth Hormone (hGH) on Prostate Cancer Cell Function
Nakonechnaya, Alena O. (East Carolina University, 2012)Human growth hormone (hGH) is a major product of the anterior pituitary. In addition to its endocrine activities, hGH overexpression in extra-pituitary tissues has been correlated with the oncogenic behavior of these ... -
An examination of the functional role of TMEFF2 in prostate cancer and the translational regulatory mechanisms controlling its expression
Overcash, Ryan Franklin (East Carolina University, 2012)Prostate cancer is the most commonly diagnosed cancer in American men and accounts for approximately 11% of cancer-related deaths. Although promising treatment strategies have been developed and are currently being tested ... -
Fesselin and caldesmon: natively unfolded proteins in smooth muscle regulation
Hamden, Svetlana (East Carolina University, 2010)Dysregulation of smooth muscle contraction is linked to diseases such as atherosclerosis, asthma, hypertension, urinary incontinence, premature birth and others. The goal of this project is to contribute to our understanding ... -
Fish oil disrupts B cell plasma membrane lateral organization and immunological synapse formation
Rockett, Benjamin Drew (East Carolina University, 2012)Fish oil has immunosuppressive properties that could provide treatment for numerous inflammatory and autoimmune disorders. The primary bioactive components of fish oil, which are the n-3 polyunsaturated fatty acids (PUFAs) ... -
The involvement of cap-independent mRNA translation in cell fate decisions
Morrison, J. Kaitlin (East Carolina University, 2014)During cell stress many biochemical processes are shut down. For example, global mRNA translation initiation is inhibited due to the disruption of the cap-dependent mRNA recruitment mechanism. One specific example of ... -
Kinetic and Thermodynamic Contributions to an Intermolecular Mechanism of Subunit Communication: Coordination of Pyruvate Carboxylase Activity Among Spatially Distinct Active Sites
Westerhold, Lauren (East Carolina University, 2016-07-13)Catalysis occurring in a multifunctional enzyme at spatially distinct active sites is controlled by an array of factors, including the structure of the enzyme, ligand binding, and productive interaction of substrates to ... -
Molecular mechanisms of TMEFF2 action in Prostate Cancer
Chen, Xiaofei (East Carolina University, 2013)The transmembrane protein with epidermal growth factor and two follistatin motifs 2 (TMEFF2) is an evolutionarily conserved type I transmembrane protein expressed in the embryo and limited adult tissues, mainly the brain ... -
Multiple Translation Factor eIF4G (IFG-1) Isoforms are Required for the Apoptosome-Dependent Activation of Germ Cell Apoptosis
Contreras, Vince (East Carolina University, 2010)Apoptosis is a naturally occurring process during animal development required for the programmed killing and removal of injured cells. Cellular insult induces a switch in translation that allows for the rapid synthesis ... -
N-3 polyunsaturated fatty acids differentially enhance B-cell mediated immunity in lean and obese mice
Teague, Heather L. (East Carolina University, 2014)Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are bioactive n-3 polyunsaturated fatty acids (PUFAs) in fish oil that exert immunomodulatory effects. The general paradigm suggests n-3 PUFAs exert immunosuppressive ... -
Neurotransmitter Metabolism by Monoamine Oxidase in Porcine Heart Differs by Location and is Increased with Obesity/Metabolic Syndrome
Carter, Kendal (East Carolina University, 2017-05-05)Monoamine Oxidase (MAO), an outer mitochondrial enzyme, catalyzes the oxidative deamination of catecholamines and other biological amines, and in the process, produces a reactive aldehyde and H2O2. Our lab has recently ... -
Novel diagnostic and analytical applications of benchtop time-domain NMR.
