Inhibition of Cdk2 activity decreases Aurora-A kinase centrosomal localization and prevents centrosome amplification in breast cancer cells
(2013-05)Centrosome amplification plays a key role in the origin of chromosomal instability (CIN) during cancer development and progression. In this study, MCF-7 breast cancer cell lines harboring abrogated p53 function (vMCF-7DNp53) ... -
Inhibition of Cdk2 kinase activity selectively targets the CD44/CD24 stem-like subpopulation and restores chemosensitivity of SUM149PT triple-negative breast cancer cells
(2014-09)Inflammatory breast cancer (IBC) is an angioinvasive and most aggressive type of advanced breast cancer characterized by rapid proliferation, chemoresistance, early metastatic development and poor prognosis. IBC tumors ... -
The inhibition of CHO-K1-BH4 cell proliferation and induction of chromosomal aberrations by brevetoxins in vitro
(East Carolina University, 2006-07)Brevetoxins (PbTxs) are highly potent trans-syn polyether neurotoxins produced during blooms of several species of marine dinoflagellates, most notably Karenia brevis. These neurotoxins act on voltage-sensitive sodium ... -
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 ... -
Inhibition of histone acetyltransferase (HAT) activity by HBZ extends beyond the p300/CBP HAT family
(2014)We previously reported that HTLV-1 basic leucine zipper factor (HBZ) interacts with the cellular coactivator p300 in cells derived from ATL patients. We further determined that HBZ directly binds to the histone acetyltransferase ... -
Inhibition of Nischarin Expression Attenuates Rilmenidine-Evoked Hypotension and Phosphorylated Extracellular Signal-Regulated Kinase 1/2 Production in the Rostral Ventrolateral Medulla of Rats
(East Carolina University, 2008-01)Imidazoline (I1)-evoked hypotension is linked to enhanced phosphorylated extracellular signalregulated kinase (pERK)1/2 production in the rostral ventrolateral medulla (RVLM). Recent cell culture findings suggest that ... -
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, ...
