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 molecular architecture of developing serotonin (5HT) neurons is poorly understood, yet its determination is likely to be essential for elucidating functional heterogeneity of these cells and the contribution of serotonergic dysfunction to disease pathogenesis. Here, we describe the purification of postmitotic embryonic 5HT neurons by flow cytometry for(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)
Major depression is a highly prevalent mental disorder and environmental factors have been strongly implicated in its pathophysiology. Clinical studies have demonstrated that stress or depression can lead to atrophy and cell loss in the hippocampus. Studies of animal models of depression have suggested that reduced neurogenesis in the adult hippocampus(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 present study revealed that the pineal gland expressed basic fibroblast growth factor (bFGF) and FGF-receptor 1 (FGFR1/flg), suggesting that bFGF in the pineal gland acts in an autocrine or paracrine manner, which is mediated by FGFR1/flg. The present study also examined gene expression of the extracellular signal-regulated kinase (ERK) family (ERK1-3)(More)
The overall distribution of mRNA for the substance P receptor (NK-1) was investigated in the rat brain by in situ hybridization histochemistry using synthetic oligonucleotide probes. The NK-1 positive cells were distributed throughout the brain. Among the positive cells an intense hybridization signal was observed in the basal ganglia and the dorsal(More)
Using in situ hybridization histochemistry and immunohistochemistry, the present study examines the cooperative regulation of transcription of molecules involved in the Ras-signal and the cAMP dependent protein kinase (PKA) pathways during peripheral nerve regeneration in rats. Injury to hypoglossal motor neurons resulted in an increase in extracellular(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)
Glutamate transporters are essential for terminating excitatory neurotransmission. Two distinct glutamate transporters, glutamate-aspartate transporter (GLAST) and excitatory amino acid transporter 4 (EAAT4), are expressed most abundantly in the molecular layer of the cerebellar cortex. GLAST is expressed in Bergmann glial processes surrounding excitatory(More)
