Erythropoietin ameliorates chemotherapy-induced toxicity in vivo
(2002-10-17)A method of reducing organ toxicity in a subject being administered a cytotoxic agent comprising concurrently administering with the cytotoxic agent erythropoietin (EPO), the EPO being administered in an amount effective ... -
Measles vaccine vectors and methods of use
(2003-03-20)The present invention provides a novel vaccine expressing a fusion of the measles hemagglutinin (H) protein and the complement component, C3d, to enhance the titers of neutralizing antibody. Plasmids were generated that ... -
Inhibition of contraction and myosin light chain phosphorylation in guinea-pig smooth muscle by p21-activated kinase 1
(East Carolina University, 2003-06-01)The p21-activated protein kinases (PAKs) have been implicated in cytoskeletal rearrangements and modulation of non-muscle contractility. Little, however, is known about the role of the PAK family members in smooth muscle ... -
Disruption of pqs synthesis using precursor analogs
(2004-01-08)The present invention concerns methods of detecting bacterial infections as well as methods of treating such infections with compounds such as methyl anthranilate. The detection and treatment of Pseudomonas is particularly ... -
Ca2+ and Ionic Strength Dependencies of S1-ADP Binding to Actin-Tropomyosin-Troponin: Regulatory Implications
(East Carolina University, 2004-09)Skeletal and cardiac muscle contraction are inhibited by the actin-associated complex of tropomyosin-troponin. Binding of Ca21 to troponin or binding of ATP-free myosin to actin reverses this inhibition. Ca21 and ATP-free ... -
The delta-14 Mutation of Human Cardiac Troponin T Enhances ATPase Activity and Alters the Cooperative Binding of S1-ADP to Regulated Actin
(East Carolina University, 2004-12-07)The complex of tropomyosin and troponin binds to actin and inhibits activation of myosin ATPase activity and force production of striated muscles at low free Ca2+ concentrations. Ca2+ stimulates ATP activity, and at ... -
Method for the synthesis of 3-substituted indolizine and benzoindolizine compounds
(2006-07-13)A method of making a compound of Formula (I) comprises reacting a compound of Formula (II) with a compound such as R1OH or R1SH, to produce said compound of Formula (I). Compounds of Formula (I) are useful, among other ... -
HuR binds to a single site on the C/EBP - beta mRNA of 3T3-L1 Adipocytes
(East Carolina University, 2007-03-30)HuR is a ligand for nuclear mRNAs containing adenylate-uridylate rich elements in the 3'- untranslated region. Once bound to the mRNA, HuR is recognized by adapter proteins which then facilitate nuclear export of the ... -
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 ... -
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 ... -
Conservation of the regulated structure of folded myosin 2 in species separated by at least 600 million years of independent evolution
(East Carolina University, 2008-04-22)The myosin 2 family of molecular motors includes isoforms regulated in different ways. Vertebrate smooth-muscle myosin is activated by phosphorylation of the regulatory light chain, whereas scallop striated adductor-muscle ... -
Tropomyosin Dynamics in Cardiac Thin Filaments: A Multisite Förster Resonance Energy Transfer and Anisotropy Study
(East Carolina University, 2008-06)Cryoelectron microscopy studies have identified distinct locations of tropomyosin (Tm) within the Ca21-free, Ca21-saturated, and myosin-S1-saturated states of the thin filament. On the other hand, steady-state Förster ... -
The Actin Binding Protein, Fesselin, is a Member of the Synaptopodin Family
(East Carolina University, 2008-07)Fesselin is a natively unfolded protein that is abundant in avian smooth muscle. Like many natively unfolded proteins, fesselin has multiple binding partners including actin, myosin, calmodulin and α-actinin. Fesselin ... -
The unique roles of IFE-1, a germline-specific isoform of eukaryotic translation factor 4E, during gametogenesis
(East Carolina University, 2009)Fertility and embryonic viability are measures of efficient germ cell growth and differentiation. During oogenesis, spermatogenesis and embryogenesis cells initially proliferate then differentiate into specific tissues. ... -
The Biochemical Characterization Of Neuronal K+ Channel N-Glycans And Their Role In Regulating K+ Channel Function
(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 ... -
The Distribution Of Regulated Actomyosin States Is Central To Cardiac Muscle Regulation And Disturbance Of This Distribution Leads To Congenital Cardiomyopathies
(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 ... -
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 ... -
