Pituitary adenylate cyclase-activating polypeptide (PACAP)-27 and PACAP-38 are neuropeptides performing a variety of physiological functions. The PACAP-specific receptor PAC1 has several variants that result mainly from alternative splicing in the mRNA region encoding the first extracellular (EC1) domain and the third intracellular cytoplasmic (IC3) loop.(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) immunoreactive neural elements have been detected in the mouse spinal cord. The discrepancy of PACAP actions in the role of sensory transmission has been proposed to have potentiation and inhibition on nociceptive responses after intrathecal application of PACAP. The aim of the present study was to(More)
BACKGROUND In Japan, growth hormone releasing peptide-2 (GHRP-2) is clinically used as a diagnostic agent for growth hormone secretion deficiency, but the therapeutic application of GHRP-2 has not been studied in anorexia nervosa. GHRP-2 reportedly exhibits agonistic action for ghrelin receptor and increases food intake. METHODS We administered GHRP-2 to(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is known as a pleiotropic neuropeptide and is present abundantly in central nervous system. During a detailed analysis of the 5'-flanking region of the mouse PACAP gene, we found and characterized two negative regulatory elements, which are homologous to the neural-restrictive silencer element, and(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is predominantly localized in the nervous system, but the underlying mechanism in its neuron-specific expression remains unclear. In addition to two neural-restrictive silencer-like element (NRSLE1 and 2), as reported previously, we have identified the third element in −1,601 to −1,581 bp from the(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) functions as a neurotrophic factor through PAC1-R, PACAP-specific receptor, in the central nervous system. On the other hand, by interacting with nicotinic acetylcholine receptor (nAChR), nicotine exhibits several neuroprotective effects. Since the relevance of PACAP and nAChR signaling has not been(More)
