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)
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)
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)
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)
Pituitary adenylate cyclase activating polypeptide (PACAP) is a new member of the secretin/glucagon/vasoactive intestinal peptide (VIP) family. It stimulates adenylate cyclase in cultured rat pituitary cells, which have PACAP-specific receptors and expression of pituitary hormones. Therefore, PACAP is considered as a hypophysiotropic hormone. If so, there(More)
BACKGROUND A number of epidemiological studies demonstrated that postprandial hyperglycemia is a risk factor for cardiovascular disease in individuals with impaired glucose tolerance. Although several laboratory studies have addressed the plausible causal role of postprandial acute hyperglycemia (glucose spikes) in the development of atherosclerosis, there(More)
Hereditary predisposition to diet-induced type 2 diabetes has not yet been fully elucidated. We recently established 2 mouse lines with different susceptibilities (resistant and prone) to high-fat diet (HFD)-induced glucose intolerance by selective breeding (designated selectively bred diet-induced glucose intolerance-resistant [SDG-R] and -prone [SDG-P],(More)
We previously reported a family with generalized resistance to thyroid hormone (GRTH) which had a point mutation with codon 448 CCT (proline) being converted to ACT (threonine) in the thyroid hormone receptor (TR) beta. To characterize functional properties of the mutant TR beta, transient expression studies were performed in COS cells. A double stranded(More)
