Multiple Translation Factor eIF4G (IFG-1) Isoforms are Required for the Apoptosome-Dependent Activation of Germ Cell Apoptosis
(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
(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 ... -
Negative Charges at Protein Kinase C Sites of Troponin I Stabilize the Inactive State of Actin
(East Carolina University, 2008-01-15)Alterations in the troponin complex can lead to increases or decreases in contractile activity. Most mutations of troponin that cause hypertrophic cardiomyopathy increase the activity of cardiac muscle fibers. In at least ... -
Neurotransmitter Metabolism by Monoamine Oxidase in Porcine Heart Differs by Location and is Increased with Obesity/Metabolic Syndrome
(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 ... -
NMR method for monitoring changes in the core of lipoprotein particles in metabolism and disease
(2017-01-14)A method is disclosed for measuring the properties of protein and lipoprotein elements in a sample. The method includes the of placing a small volume of a sample into a NMR instrument tuned to measure a particular nucleus, ... -
Novel autoinducer molecules and uses therefor
(2002-03-07)Novel bacterial quinolone signal molecules and, more particularly, pseudomonas quinolone signal ('PQS') molecules, e.g., 2-heptyl-3hydroxy-4-quinolone, and analogs and derivatives thereof are described, Therapeutic ... -
Novel diagnostic and analytical applications of benchtop time-domain NMR.
(East Carolina University, 2015)High-resolution nuclear magnetic resonance (NMR) spectroscopy is a powerful technique, yet practical application outside of the research laboratory has been limited due to the high cost and complexity of the instrumentation. ... -
Post-Transcriptional Regulation of mRNA Metabolism during Differentiation of 3T3-L1 Cells: Role of HuR
(East Carolina University, 2010)Our studies address early control points in the differentiation process that are necessary for expression as well as the maintenance of the adipocyte phenotype. We have focused on the post-transcriptional regulation of ... -
Racial difference in Acylation Stimulating Protein (ASP) correlates to triglyceride in non-obese and obese African American and Caucasian women
(East Carolina University, 2009-04-17)Background: Acylation Stimulating Protein (ASP) has been shown to influence adipose tissue triglyceride (TG) storage. The aim was to examine ethnic differences in ASP and leptin levels in relation to lipid profiles and ... -
Regulation of lipoprotein lipase mRNA content in 3T3-L1 cells by tumour necrosis factor.
(East Carolina University, 1988-02-01)Tumour necrosis factor (TNF) was previously shown to suppress lipoprotein lipase (LPL) synthesis and activity in 3T3-L1 adipocytes. The present study examined the effect ofTNF on amounts ofmRNA for LPL in 3T3-Ll cells. ... -
Regulation of Transglutaminase 2 structure and function by Ca²⁺ and [alpha]-synuclein
(East Carolina University, 2016-07-14)Transglutaminase 2 (TG2) catalyzes the Ca2+-dependent transamidation of protein substrates between glutamine and lysine residues by formation of an N[epsilon]-([gamma]-L-glutamyl)-L-lysine isopeptide bond. The Ca2+-dependent ... -
Relationship of N-glycans to Neuronal Dysfunction
(East Carolina University, 2019-06-07)N-glycosylation is important in regulating protein activity and serves several vital roles contributing to protein folding, protein assembly, stability, and interactions. Changes in branching of N-glycans are linked to ... -
Resolving the Role of POU1F1 in Human Growth Hormone Locus Activation
(East Carolina University, 2012)The human growth hormone gene ( hGH-N) is regulated by a distal locus control region (LCR) composed of five deoxyribonuclease I hypersensitive sites (HSs). The region encompassing HSI and HSII contains the predominant ... -
Retinoids Potentiate Clinically Relevant Cellular Responses through RARα/RXR Nuclear Receptor Synergism in Cutaneous T Cell Lymphoma
(East Carolina University, 2015-12-15)The heterogeneity of cutaneous T cell lymphoma (CTCL) has stifled treatment options and hindered cure development. Despite the heterogeneous nature of CTCLs, a hallmark of all variants is malignant T cell infiltration of ... -
The RXR-alpha C-terminus T462 is a NMR sensor for coactivator peptide binding
(East Carolina University, 2008-02-22)The C-terminal activation function-2 (AF-2) helix plays a crucial role in retinoid X receptor alpha (RXRα)-mediated gene expression. Here, we report a nuclear magnetic resonance (NMR) study of the RXRα ligand-binding domain ... -
Selective Recruitment of Germ Cell mRNAs by eIF4 Factors
(East Carolina University, 1/13/16)During germ line development critical steps in the proliferation and differentiation of stem cells into oocytes and sperm are regulated by mRNA translational control. This regulation changes the subset of proteins being ... -
Some Cardiomyopathy-Causing Troponin I Mutations Stabilize a Functional Intermediate Actin State
(East Carolina University, 2009-03-18)We examined four cardiomyopathy-causing mutations of troponin I that appear to disturb function by altering the distribution of thin filament states. The R193H (mouse) troponin I mutant had greater than normal actin-activated ...
