The effect of brevenal on brevetoxin-induced DNA damage in human lymphocytes
(East Carolina University, 2005-11)Brevenal is a nontoxic short-chain trans-syn polyether that competes with brevetoxin (PbTx) for the active site on voltage-sensitive sodium channels. The PbTxs are highly potent polyether toxins produced during blooms of ... -
Effect of testosterone replacement or duration of castration on baroreflex bradycardia in conscious rats
(East Carolina University, 2005-03-30)Background: In this study, we tested the hypothesis that 17β-estradiol contributes to testosterone-mediated restoration of baroreflex-mediated bradycardia in short-term (3 weeks) castrated rats. Further, a reported increase ... -
Estrogen-dependent enhancement of NO production in the nucleus tractus solitarius contributes to ethanol-induced hypotension in conscious female rats
(East Carolina University, 2009-02)Background- Our previous pharmacological and cellular studies showed that peripheral (cardiac and vascular) NOS-derived NO is implicated in the estrogen-dependent hypotensive action of ethanol in female rats. The objective ... -
Evidence for the presence of A1 adenosine receptors in the aorta of spontaneously hypertensive rats
(East Carolina University, 2001-12)1 Isolated aortic rings (endothelium-intact and -denuded) from spontaneously hypertensive (SHR) and Wistar-Kyoto (WKY) rats were used in this study to examine the vasoactive e ects of various adenosine analogues. 2 In ... -
Extracellular matrix induction method to produce pancreatic islet tissue
(1990-06-19)A method and composition of regenerating tissue. More specifically, a method for regenerating pancreatic islet tissue having the histological and insulin-containing properties of islets typically found in neonatal or adult ... -
The extracellular processing of aggrecan aggregate and its effect on CD44 mediated internalization of hyaluronan.
(East Carolina University, 2015)In many cells the hyaluronan receptor CD44 mediates the endocytosis of hyaluronan and its delivery to endosomes / lysosomes. The regulation of this process remains largely unknown. In most extracellular matrices hyaluronan ... -
Functional Characterization of a Small Conductance GIRK Channel in Rat Atrial Cells
(East Carolina University, 2004-11)Muscarinic K1 (KACh) channels are key determinants of the inhibitory synaptic transmission in the heart. These channels are heterotetramers consisting of two homologous subunits, G-protein-gated inwardly rectifying K1 ... -
Functions of claudin-7 in human lung cancer
(East Carolina University, 2012)Lung cancer is the second most common cancer and the most common cause of cancer-related death in both men and women in the United States with a very poor overall 5-year survival rate. Nearly 95% of the lung cancer originates ... -
FUNCTIONS OF CLAUDIN-7 IN THE SELF-RENEWAL OF INTESTINAL EPITHELIUM
(East Carolina University, 8/5/2020)Tight junctions (TJ) are located at the most apical region of the junctional complex and contain many integral membrane proteins. Claudin 7 (Cldn7) is a TJ membrane protein located at the apical TJ and basolateral side of ... -
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 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 ... -
The intracellular proteolytic fragment of CD44 alters CD44 function in chondrocytes
(East Carolina University, 2010)CD44 is an adhesion molecule involved in several biological functions and the primary receptor for hyaluronan (HA). In cartilage, CD44 participates in the interplay between cells and the extracellular matrix to fine tune ... -
INVESTIGATING MECHANISMS REGULATING MAMMALIAN SPERMATOGONIAL DIFFERENTIATION AND MEIOTIC INITIATION
(East Carolina University, 2022-06-27)Spermatogonia differentiation and meiotic initiation are complex processes essential for male fertility. Despite knowing for nearly 60 years that retinoic acid (RA) is instrumental for successful production of functional ... -
