Mammalian bombesin-like peptides are widely distributed in the central nervous system as well as in the gastrointestinal tract, where they modulate smooth-muscle contraction, exocrine and endocrine processes, metabolism and behaviour. They bind to G-protein-coupled receptors on the cell surface to elicit their effects. Bombesin-like peptide receptors cloned(More)
The present study attempted to explore the gene expression of the subunits (GluR1-4) of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type receptor, subunit (GluR5) of kainic acid (KA)-type receptor, NR1 [a subunit of N-methyl-D-aspartate (NMDA) receptors] and the possible glutamate-binding subunit of an NMDA receptor complex in the(More)
The expression of oxytocin receptor (OT-R) mRNA in the rat central nervous system was examined by in situ hybridization histochemistry using cRNA probe. Wide distribution of cells expressing OT-R mRNA was observed not only in the hypothalamus, but also in other regions. There were high levels of OT-R mRNA in the anterior olfactory nuclei, tenia tecta,(More)
Gastrin-releasing peptide (GRP) is a mammalian bombesin-like peptide which is widely distributed in the central nervous system as well as in the gastrointestinal tract. GRP binds to its high affinity receptor (GRPR) to elicit a wide spectrum of biological effects on behavior, digestion, and metabolism. To define the in vivo function of GRPR, we generated(More)
Effects of YM-09151-2 and five other neuroleptics (haloperidol, spiperone, chlorpromazine, sulpiride and clozapine) on the binding of [3H]-ligands to nine different receptors (alpha 1-adrenergic, alpha 2-adrenergic, beta-adrenergic, muscarinic, D2-dopaminergic, H1-histaminergic, 5HT1-serotonergic, 5HT2-serotonergic and opiate receptors) and on(More)
OBJECTIVE To evaluate the effects of walking combined with diet therapy (1,000-1,600 kcal/day) on insulin sensitivity in obese non-insulin-dependent diabetes mellitus (NIDDM) patients. RESEARCH DESIGN AND METHODS Subjects were divided into two groups: 10 patients were managed by diet alone (group D), and 14 patients were placed in the diet and exercise(More)
Two types of [3H]dopamine binding were found in the synaptic membrane fractions of canine caudate nucleus and referred to as Dl (associated with adenylate cyclase) and Dz (independent of adenylate cyclase) dopamine receptors. Both receptors were present primarily in the membrane fractions and showed a similar subcellular distribution except for the(More)
Expression of serotonin (5-hydroxytryptamine, 5-HT) transporter mRNA in the rat brain was examined by in situ hybridization histochemistry with a synthetic oligonucleotide probe. 5-HT transporter mRNA was expressed in neurons in most of the raphe nuclei. The dorsal and median raphe nuclei contained intensely labeled neurons, while the caudal linear nucleus,(More)
Intraventricular administration to mice porcine calcitonin (10 U/kg) as well as of morphine (3 microgram/kg) elevated the threshold pressure of stimuli applied to the base of the tail as assessed by squeaking, struggling or biting, all of which were regarded as manifestations of pain sensation in the animals. Pretreatment with an opiate antagonist,(More)
