(Kluwer Academic Publishers; Springer, 2005-03)
Evaluation of Novel Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-01)
The epidermal growth factor system is a well characterized growth factor receptor pathway, the deregulation of which has been be associated with neoplastic growth. Overexpression or amplification of the epidermal growth ...
A rapid attenuation of muscarinic agonist stimulated phosphoinositide hydrolysis precedes receptor sequestration in human SH-SY-5Y neuroblastoma cells
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-05)
Agonist occupancy of muscarinic cholinergic receptors in human SH-SY-5Y neuroblastoma cells elicited two kinetically distinct phases of phosphoinositide hydrolysis when monitored by either an increased mass of inositol ...
Repeated haloperidol increases both calmodulin and a calmodulin-binding protein in rat striatum
(Elsevier, 1994-12)
Repeated treatment with the antipsychotic drug, haloperidol, leads to an increased behavioral sensitivity to dopamine agonists exhibited upon withdrawal from the drug. An increase in the particulate content of the endogenous ...
Opioid receptor regulation of 5-hydroxytryptamine release from the rat hippocampus measured by in vivo microdialysis
(Elsevier, 1993-06-04)
The modulation of serotonin (5-HT) release by opioid receptors in the hippocampus of the awake, unrestrained rat was evaluated by use of in vivo microdialysis. The hippocampus was perfused with Ringer's solution (2 [mu]l/min), ...
[alpha]2-Adrenoreceptors in rat brain are decreased after long-term tricyclic antidepressant drug treatment
(Elsevier, 1981-04-06)
After two weeks of twice-daily administration of amitriptyline to rats, the binding of [3H]clonidine to presynaptic [alpha]2-adrenoreceptors was decreased in membranes isolated from 5 areas of the rat brain. After one day ...
Decreased formation of inositol trisphosphate in Madin-Darby canine kidney cells under conditions of [beta]-glucosidase inhibition
(Elsevier, 1992-02-01)
Recent work has demonstrated the enhancement of hormone-stimulated inositol trisphosphate formation in renal epithelial cells under conditions of glucosylceramide depletion. The role of glucosylceramide metabolism was ...
Dysplasia in Barrett esophagus
(Wiley Subscription Services, Inc., A Wiley Company, 2004-04-15)
BACKGROUND Dysplasia in Barrett esophagus is a premalignant condition that is associated with an increased risk of developing esophageal adenocarcinoma. Unfortunately, clinical investigation aimed at prevention of progression ...
Regulation of Myo-Inositol Homeostasis in Differentiated Human NT2-N Neurons
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-05)
We have investigated the possible role of second messengers on inositol homeostasis in NT2-N cells, human central nervous system neurons obtained by terminal differentiation of teratocarcinoma precursors. Uptake of inositol ...
Alteration of enzyme activity in rat liver following the acute and chronic administration of nicotine
(Elsevier, 1970-05)
The ip injection of nicotine (2 or 4 mg/kg) to rats produced an increase in tryptophan pyrrolase activity in liver within 2 hours after drug administration. The elevation in enzyme activity reached a peak at 4 hours after ...
