Easy-to-use strategy for reference gene selection in quantitative real-time PCR experiments.

Naunyn Schmiedebergs Arch Pharmacol 2016 Dec 20;389(12):1353-1366. Epub 2016 Sep 20.

Klinik für Anästhesiologie & Intensivmedizin, Universität Duisburg-Essen and Universitätsklinikum Essen, Hufelandstr. 55, D-45122, Essen, Germany.

Real-time PCR is an indispensable technique for mRNA expression analysis but conclusions depend on appropriate reference gene selection. However, while reference gene selection has been a topic of publications, this issue is often disregarded when measuring target mRNA expression. Therefore, we (1) evaluated the frequency of appropriate reference gene selection, (2) suggest an easy-to-use tool for least variability reference gene selection, (3) demonstrate application of this tool, and (4) show effects on target gene expression profiles.

Publication trends in Naunyn-Schmiedeberg's Archives of Pharmacology: focus on pharmacology in Egypt.

Naunyn Schmiedebergs Arch Pharmacol 2013 Nov 14;386(11):929-33. Epub 2013 Sep 14.

Department of Pharmacology and Toxicology, Faculty of Pharmacy, Alexandria University, Alexandria, Egypt.

In a previous analysis of the country of origin of papers published in Naunyn-Schmiedeberg's Archives of Pharmacology, a major shift toward contributions from emerging market countries, was noticed in comparison of 2010 to 2001 publications. Repeating such analysis for 2012 publications in the journal confirmed this trend. An interesting new trend was the emerging presence of papers from a variety of Islamic countries including Egypt.

The in vitro pharmacological profile of TD-1211, a neutral opioid receptor antagonist.

Naunyn Schmiedebergs Arch Pharmacol 2013 Jun 4;386(6):479-91. Epub 2013 Apr 4.

Department of Molecular and Cellular Biology, Theravance, Inc., 901 Gateway Boulevard, South San Francisco, CA 94080, USA.

The clinical efficacy of opioid receptor antagonists for the treatment of opioid-induced constipation (OIC) is established. Peripherally selective antagonists are intended to provide OIC symptom relief without compromising the analgesic effects of centrally penetrant opioid agonists. We describe the in vitro profile of a novel opioid receptor antagonist, TD-1211, at recombinant (human μ and δ, and guinea pig κ) and rodent native opioid receptors. Read More

Excitotoxic hippocampal membrane breakdown and its inhibition by bilobalide: role of chloride fluxes.

Pharmacopsychiatry 2003 Jun;36 Suppl 1:S78-83

Department of Pharmacology, Johannes Gutenberg University of Mainz, Mainz, Germany.

We have previously shown that hypoxia and N-methyl-D-aspartate (NMDA) receptor activation induce breakdown of choline-containing phospholipids in rat hippocampus, a process which is mediated by calcium influx and phospholipase A (2) activation. Bilobalide, a constituent of Ginkgo biloba, inhibited this process in a potent manner (Weichel et al., Naunyn-Schmiedeberg's Arch. Read More

Inhibition of 5-HT3 receptors by propofol: equilibrium and kinetic measurements.

Neuropharmacology 2000 Apr;39(6):1064-74

Klinik für Anästhesiologie und spezielle Intensivmedizin, Universitätskliniken Bonn, Sigmund-Freud Strasse 25, D-53105, Bonn, Germany.

Patch-clamp/rapid solution exchange experiments as well as tracer ([14C]-guanidinium) influx measurements were applied to investigate effects of propofol on 5-HT3 receptor channels and compare the results with those obtained with pentobarbital. Currents induced by 30 microM 5-HT were recorded in outside-out patches from N1E-115 cells. Application of propofol 45 s before and during 5-HT application inhibited peak-currents and integrated current responses in a concentration-dependent manner (IC50 values=14. Read More

Effects of GABAB receptor antagonism on the development of pentylenetetrazol-induced kindling in mice.

Brain Res 1998 Nov;809(2):182-8

Department of Pharmacology and Toxicology, Higher Medical School Plovdiv, Bulgaria.

Pentylenetetrazol (PTZ) administered chronically in rodents induces kindling which is considered to be a model of chronic epilepsy mediated through a specific interaction with the GABA-gated chloride ionophore. PTZ kindling also impairs shuttle-box learning indicating a possible modulation of memory storage [A. Becker, G. Read More

Identification and characterisation of heterogeneous somatostatin binding sites in rat distal colonic mucosa.

Naunyn Schmiedebergs Arch Pharmacol 1996 Nov;354(5):543-9

Glaxo Institute of Applied Pharmacology, Department of Pharmacology, University of Cambridge, UK.

We have previously shown that the somatostatin (SRIF) sst2 receptor-selective peptide, BIM-23027, is a potent antisecretory agent in rat isolated distal colonic mucosa (RDCM) and in radioligand binding studies in RDCM membranes, it only maximally inhibited approximately 40% of [125I]-Tyr11-SRIF-14 binding (McKeen ES, Feniuk W, Humphrey PPA (1995) Naunyn-Schmiedeberg's Arch Pharmacol 352:402-411). The aim of this study was to characterise the BIM-23027-sensitive and -insensitive SRIF binding sites in more detail and to compare their properties with those of the recombinant sst2 receptor stably expressed in mouse fibroblast (Ltk-) cells. SRIF-14, SRIF-28, CGP-23996 and D Trp8-SRIF-14 abolished [125I]-Tyr11-SRIF-14 binding (pIC50 values, 8. Read More

Promotion of cell growth by stimulation of cloned human 5-HT1D receptor sites in transfected C6-glial cells is highly sensitive to intrinsic activity at 5-HT1D receptors.

Naunyn Schmiedebergs Arch Pharmacol 1996 Jul;354(2):136-44

Laboratory of Cellular and Molecular Neurobiology, Centre de Recherche Pierre Fabre, Castres, France.

5-Hydroxytryptamine (serotonin, 5-HT), essentially known as a neurotransmitter and vasoactive agent, also functions as a mitogen in various cell types through several different second messenger systems. Stimulation of cloned human 5-HT1D receptor sites by sumatriptan in stably transfected rat C6-glial/5-HT1D cells promotes cell growth (Pauwels et al.

Comparison of cloned and pharmacologically defined rat tissue alpha 1-adrenoceptor subtypes.

Naunyn Schmiedebergs Arch Pharmacol 1994 Aug;350(2):136-42

Department of Medicine, University of Essen, Germany.

Multiple alpha 1-adrenoceptor subtypes have been defined by pharmacological and receptor cloning techniques, but the precise alignment of cloned and pharmacologically-defined subtypes is still unclear. We have compared the affinities of 8 subtype-selective compounds at three cloned alpha 1-adrenoceptor subtypes (rat alpha 1B, bovine alpha 1C, rat alpha 1A/D) with those previously determined by the same methods in rat spleen, cerebral cortex, and kidney (Naunyn-Schmiedeberg's Arch.

Sulphate conjugation of p-nitrophenol (p-NP) in the liver and platelet cytosol of guinea pigs, rabbits and dogs were studied.

Competitive antagonism by recognized 5-HT2 receptor antagonists at 5-HT1C receptors in pig choroid plexus.

Naunyn Schmiedebergs Arch Pharmacol 1991 Aug;344(2):137-42

Department of Pharmacology, School of Pharmacy, Hacettepe University, Ankara, Turkey.

The effects of several antagonists, known to interact with 5-HT2 receptors (ritanserin, LY 53857, ICI 169,369, methysergide, mesulergine and ketanserin), were tested against 5-HT-stimulated production of inositol phosphate in pig choroid plexus, a 5-HT1C receptor model. These antagonists produced dextral shifts of the concentration response curve to 5-HT in a parallel manner, without depressing significantly the maximal response. The following pA2 values (in parentheses) were obtained: mesulergine (8. Read More

Palytoxin-induced permeability changes in excitable membranes.

Biochim Biophys Acta 1985 Aug;818(1):55-60

Palytoxin, a toxin isolated from the Caribean corrall Palythoa caribaeorum, increases the cation permeability of excitable membranes in vitro. Three membrane systems have been investigated: axonal membranes from crayfish walking leg nerves, membranes rich in nicotinic acetylcholine receptor isolated from Torpedo californica electric tissue and, for control, artificial liposomes. Ion permeability of the latter was not affected by palytoxin, but with both biological membranes an increase in cation permeability was observed at a palytoxin concentration of 0. Read More

In a previous article [Naunyn-Schmiedeberg's Arch Pharmacol (1981) 316:266-272] transport of a number of organic ions across lipid bilayers was investigated using single bilayer liposomes. In this investigation the translocation of structurally closely related barbiturates across lipid bilayers is studied. The anionic form of the barbiturates can pass lipid bilayers, provided that the lipophilicity of the 5,5-disubstituted side chain is high enough. Read More
