Kif5B and Kifc1 Interact and Are Required for Motility and Fission of Early Endocytic Vesicles in Mouse Liver
(East Carolina University, 2007-05)Early endocytic vesicles loaded with Texas Red asialoorosomucoid were prepared from mouse liver. These vesicles bound to microtubules in vitro, and upon ATP addition, they moved bidirectionally, frequently undergoing fission ... -
Kinetics of Binding of Caldesmon to Actin
(East Carolina University, 1995-04-28)The time course of interaction of caldesmon with actin may be monitored by fluorescence changes that occur upon the binding of 12-(N-methyl-N-(7-nitrobenz-2-oxa-l,3-diazol-4-yl))-labeled caldesmon to actin or to acrylodan ... -
Lesional modulation of peripheral monocyte leucotactic responsiveness in leprosy.
(East Carolina University, 1987-11)Because the accumulation and activation of mononuclear phagocytes are critical to the host response to intracellular microbial pathogens, we evaluated mechanisms of peripheral monocyte leucotactic regulation in leprosy. ... -
Lipid mediators of insulin resistance: ceramide signalling down-regulates GLUT4 gene transcription in 3T3-L1 adipocytes.
(East Carolina University, 1996-10-01)We have previously demonstrated that chronic exposure of 3T3- L1 adipocytes to tumour necrosis factor-α (TNF) resulted in a marked decrease (~90%) in cellular GLUT4 (insulin-responsive glucose transporter) mRNA content as ... -
LLL-3 inhibits STAT3 activity, suppresses glioblastoma cell growth and prolongs survival in a mouse glioblastoma model
(East Carolina University, 2009-01-13)Persistent activation of the signal transducer and activator of transcription 3 (STAT3) signalling has been linked to oncogenesis and the development of chemotherapy resistance in glioblastoma and other cancers. Inhibition ... -
Localization and Characterization of a 7.3-kDa Region of Caldesmon Which Reversibly Inhibits Actomyosin ATPase Activity
(East Carolina University, 1992-08-15)Cleavage of caldesmon with chymotrypsin yields a series of fragments which bind both calmodulin and actin and inhibit the binding of myosin subfragments to actin and the subsequent stimulation of ATPase activity. Several ... -
A Long Helix from the Central Region of Smooth Muscle Caldesmon
(East Carolina University, 1991-07-25)The central region of smooth muscle caldesmon is predicted to form α-helices on the basis of its primary structure. We have isolated a fragment (CT54) that contains this region. The hydrodynamic properties and the electron ... -
Long Noncoding RNA Expression Signatures of Metastatic Nasopharyngeal Carcinoma and Their Prognostic Value
(2015)Long noncoding RNAs (lncRNAs) have recently been found to play important roles in various cancer types. The elucidation of genome-wide lncRNA expression patterns in metastatic nasopharyngeal carcinoma (NPC) could reveal ... -
Long-term effect of insulin on glucose transport and insulin binding in cultured adipocytes from normal and obese humans with and without non-insulin-dependent diabetes.
(East Carolina University, 1987-10)We have tested the hypothesis that in vitro exposure of insulin- resistant adipocytes with insulin results in improved insulin action. A primary culture system of adipocytes from obese subjects with ... -
Lymphocytic hypophysitis.
(East Carolina University, 1994-05)LYMPHOCYTIC HYPOPHYSITIS is an unusual disorder that nearly exclusively affects women; fewer than 50 cases have been reported in the literature. The present case also is unusual because a normal computed tomographic (CT) ... -
Mast cells and the IL-33/ST2 axis are essential determinants of carbon nanotube toxicity
(East Carolina University, 2012)The rise of nanomaterial use in a variety of applications, including biomedical imaging and drug delivery, has led to concern about the potentially hazardous impacts on human health. Mast cells are critical for innate and ... -
MCF-7 breast cancer cells transfected with protein kinase C-alpha exhibit altered expression of other protein kinase C isoforms and display a more aggressive neoplastic phenotype.
(East Carolina University, 1995-04)Increased protein kinase C (PKC) activity in malignant breast tissue and positive correlations between PKC activity and expression of a more aggressive phenotype in breast cancer cell lines suggest a role for this signal ... -
Mechanisms controlling the acquisition of a cardiac phenotype by liver stem cells
(East Carolina University, 2007-03-06)The mechanisms underlying stem cell acquisition of a cardiac phenotype are unresolved. We studied early events during the acquisition of a cardiac phenotype by a cloned adult liver stem cell line (WB F344) in a cardiac ... -
Mechanisms for central cannabinoid receptor 1 evoked sympathoexcitation/pressor response in conscious rats
(East Carolina University, 2010)The main goal of the current study was to elucidate the molecular mechanisms implicated in central cannabinoid receptor 1 (CB1R)-evoked sympathoexcitation/pressor response. In pursuit of this goal, the candidate first ... -
Mechanisms Involved in the Cerebrovascular Dilator Effects of N-methyl-D-aspartate in Cerebral Cortex
(East Carolina University, 2007-11)Glutamate and its synthetic analogues N-methyl-D-aspartate (NMDA), kainate, and alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA) are potent dilator agents in the cerebral circulation. The close linkage between ... -
MicroRNA profiling in the left atrium in patients with non-valvular paroxysmal atrial fibrillation
(2015-08)Background We aimed to identify the miRNA expression profiles in left atrial appendage, with the intention of identifying miRNAs that were significantly associated with non-valvular paroxysmal AF. Methods The RNA ... -
A Minimally-Invasive Procedure for Sexing Young Zebra Finches
(East Carolina University, 2007-08-15)Zebra finches have been widely used to study neurobiology underlying vocal development. Because only male zebra finches learn song, efficient developmental use of these animals requires early determination of sex at ages ... -
Mitochondrial H₂O₂ emission and cellular redox state link excess fat intake to insulin resistance in both rodents and humans
(2009-03)High dietary fat intake leads to insulin resistance in skeletal muscle, and this represents a major risk factor for type 2 diabetes and cardiovascular disease. Mitochondrial dysfunction and oxidative stress have been ... -
Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene, cblA, encoding the species-specific beta-lactamase.
(East Carolina University, 1994-08)The gene, cbl, encoding the species-specific, clavulanate-susceptible, endogenous cephalosporinase was cloned from Bacteroides uniforinis WAL-7088. The nucleotide sequence was determined, and the cbl structural gene was ...
