Inhibition of Quorum Sensing by a Pseudomonas aeruginosa dksA Homologue
(East Carolina University, 2001-03)The Pseudomonas aeruginosa las (lasR-lasI) and rhl (rhlR-rhlI) quorum-sensing systems regulate the expression of several virulence factors, including elastase and rhamnolipid. P. aeruginosa strain PR1-E4 is a lasR deletion ... -
Inhibition of vascular smooth muscle growth via signaling crosstalk between AMP-activated protein kinase and cAMP-dependent protein kinase
(2012-10)Abnormal vascular smooth muscle (VSM) growth is central in the pathophysiology of vascular disease yet fully effective therapies to curb this growth are lacking. Recent findings from our lab and others support growth control ... -
Initial Characterization of the FlgE Hook High Molecular Weight Complex of
(2014)The spirochete periplasmic flagellum has many unique attributes. One unusual characteristic is the flagellar hook. This structure serves as a universal joint coupling rotation of the membrane-bound motor to the flagellar ... -
Insertional activation of cepA leads to high-level beta-lactamase expression in Bacteroides fragilis clinical isolates.
(East Carolina University, 1994-07)Bacteroides fragilis is an important opportunistic pathogen of humans and is resistant to many drugs commonly used to treat anaerobic infections, including P-lactams. A strain set comprised of B. fragilis isolates producing ... -
Insulin responsiveness in skeletal muscle is determined by glucose transporter (Glut4) protein level.
(East Carolina University, 1990-09-01)Glucose transport in skeletal muscle is mediated by two distinct transporter isoforms, designated muscle/adipose glucose transporter (Glut4) and erythrocyte/HepG2/brain glucose transporter (Glutl), which differ in both ... -
Insulin-like growth factor I binding in hepatocytes from human liver, human hepatoma, and normal, regenerating, and fetal rat liver.
(East Carolina University, 1988-04)Insulin-like growth factor-I (IGF-I) in human hepatoma cells (HEP-G2) has, in addition to its effect on cell growth, shortterm metabolic effects acting through its own receptor. We have demonstrated that normal ... -
Insulin/IGF1-PI3K-dependent nucleolar localization of a glycolytic enzyme – phosphoglycerate mutase 2, is necessary for proper structure of nucleolus and RNA synthesis
(2015-07)Phosphoglycerate mutase (PGAM), a conserved, glycolytic enzyme has been found in nucleoli of cancer cells. Here, we present evidence that accumulation of PGAM in the nucleolus is a universal phenomenon concerning not only ... -
Intact Purine Biosynthesis Pathways Are Required for Wild-Type Virulence of Brucella abortus 2308 in the BALB/c Mouse Model
(East Carolina University, 2004-08)Brucella abortus 2308 derivatives with mini-Tn5 insertions in purE, purL, and purD display significant attenuation in the BALB/c mouse model, while isogenic mutants with mini-Tn5 insertions in pheA, trpB, and dagA display ... -
The Interaction of Caldesmon with the COOH Terminus of Actin
(East Carolina University, 1991-10-25)Caldesmon interacts with the NH2-terminal region of actin. It is now shown in airfuge centrifugation experiments that modification of the penultimate cysteine residue of actin significantly weakens its binding to caldesmon ... -
Interaction of memantine with ethanol consumption and dopaminergic function in high ethanol preferring rats
(East Carolina University, 2009)N-methyl-D-aspartate (NMDA) receptor antagonists have been reported to decrease ethanol consumption in rodents, but these drugs often produce adverse side effects. Memantine is a neuroprotective and low-affinity, ... -
Interactions of a Dopamine D Receptor Agonist with Glutamate NMDA Receptor Antagonists on the Volitional Consumption of Ethanol by the mHEP Rat
(2013-03)Stimulation of the dopamine D1 receptor is reported to cause the phosphorylation of DARPP-32 at the thre34 position and activates the protein. If intracellular Ca2+ is increased, such as after activation of the glutamate ... -
Interference with Pseudomonas quinolone signal synthesis inhibits virulence factor expression by Pseudomonas aeruginosa
(East Carolina University, 2001-09-25)Pseudomonas aeruginosa is an opportunistic pathogen that controls numerous virulence factors through intercellular signals. This bacterium has two quorum-sensing systems (las and rhl), which act through the intercellular ... -
Interlaboratory Evaluation of Rodent Pulmonary Responses to Engineered Nanomaterials: The NIEHS Nano GO Consortium
(2013-05)Background: Engineered nanomaterials (ENMs) have potential benefits, but they also present safety concerns for human health. Interlaboratory studies in rodents using standardized protocols are needed to assess ENM ... -
Interprofessional obesity treatment: An exploration of current literature and practice
(2021)This exploratory exercise was to gain an understanding of current literature and practice regarding adult Interprofessional obesity treatment team practice. A synthesis of 87 articles and 9 websites and a qualitative ... -
Interrelated role of Notch signaling and mTORC pathways in prostate cancer cell survival and growth
(East Carolina University, 2014)Prostate cancer is currently the second highest leading cause of cancer death in men. Notch is a transmembrane receptor protein that is part of a signaling pathway necessary in the normal development of the prostate. ...
