Pituitary adenylate cyclase-activating polypeptide (PACAP) is a recently identified member of the secretin/vasoactive intestinal polypeptide (VIP) family. There are at least two types of receptor for PACAP: type I (PACAPR), which specifically binds PACAP; and type II (VIP/PACAPR), which binds both PACAP and VIP. The localization of PACAPR in the rat brain(More)
Pituitary adenylate cyclase-activating polypetide (PACAP) exists in two amidated forms, PACAP38 and PACAP27, which are expressed in the magnocellular and parvocellular neurons of the paraventricular nucleus (PVN) and the magnocellular neurons of the supraoptic nucleus (SON) of the hypothalamus. The prohormone convertases PC1 and PC2, subtilisin-like PCs of(More)
The physiological substrate for proprotein convertase (PC) 4, which is expressed only in the testis, has remained unknown. Pituitary adenylate cyclase activating polypeptide (PACAP), originally isolated from the hypothalamus, exists as two amidated forms with 38 (PACAP38) and 27 (PACAP27) residues. PACAP-like immunoreactivity (PACAP-li) is found not only in(More)
Growth hormone secretagogues (GHSs) stimulate GH secretion and food intake. GHS receptor (GHS-R) mRNA has been identified mainly in the arcuate nucleus (Arc) and ventromedial nucleus of the hypothalamus and in the pituitary. Ghrelin, an endogenous ligand for GHS-R, has recently been purified from rat stomach. Although ghrelin is also expressed in the(More)
Growth hormone (GH) secretagogues (GHSs), which stimulate GH secretion, are synthetic compounds that act through the GHS receptor (GHS-R) which has been recently cloned. We raised an antiserum in a rabbit against a synthetic peptide corresponding to amino acid residues 248-260 of the third intracellular loop of the rat GHS-R. A competitive immunoassay(More)
AIMS To evaluate treatment satisfaction before and after starting biphasic insulin aspart 30 (BIAsp 30) therapy in patients with type 2 diabetes mellitus (T2D) in the IMPROVE study Japan using the Diabetes Medication Satisfaction (DiabMedSat) questionnaire. METHODS The DiabMedSat questionnaire assesses overall satisfaction with drug therapy for diabetes(More)
GH secretagogue (GHS)/ghrelin stimulates GH secretion by binding mainly to its receptor (GHS-R) on GHRH neurons in the arcuate nucleus (Arc) of the hypothalamus. GHRH, somatostatin, and neuropeptide Y (NPY) in the hypothalamus are involved in the regulatory mechanism of GH secretion. We previously created transgenic (Tg) rats whose GHS-R expression is(More)
To clarify the role of ghrelin and its receptor (GHS-R) in the regulatory mechanism of energy metabolism, we analyzed transgenic (Tg) rats expressing an antisense GHS-R mRNA under the control of the tyrosine hydroxylase (TH) promoter. Tg rats showed lower visceral fat weight and higher O(2) consumption, CO(2) production, rectal temperature, dark-period(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide which was first isolated from ovine hypothalamic tissue by screening for pituitary adenylate cyclase stimulating activity. Our previous data showed that radioimmunoassayable PACAP and PACAP-binding sites were detected in the whole rat brain as early as embryonic day 14(E14). In(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the secretin/glucagon/vasoactive intestinal peptide (VIP) family. Our immunohistochemical and in situ hybridization histochemical studies indicated that PACAP-like immunoreactivity (PACAP-LI) and its mRNA were present in the germ cells in the rat testis. Because the testicular(More)
