Arginine vasopressin stimulates 32P labeling of phosphoinositides in rat pineal gland

Generation of the Melatonin Endocrine Message in Mammals: A Review of the Complex Regulation of Melatonin Synthesis by Norepinephrine, Peptides, and Other Pineal Transmitters

“…Among these cells were a number of pinealocytes and fibroblast-like cells. These data are in agreement with the observation that VP increases PI turnover in the rat pineal gland (Novotna et al, 1995) but not with that of Schomerus et al (1995) who reported no effect of VP on the Ca 2ϩ i level in cultured rat pinealocytes.…”

Components and connections of the circadian timing system in mammals

“…Interestingly, evidence exists that the second paraventricular nonapeptide, OT, is without effect on pineal function (Kalsbeek et al 1993;Reuss et al 1993). In conclusion, the findings described above reveal the involvement of the PVN in mechanisms of circadian regulation and suggest a modulatory role of AVP for melatonin synthesis, probably via the V1 receptor and the phosphoinositol signalling pathway (Novotna et al 1995).…”

Role of the GRP/GRPR System in Regulating Brain Functions

“…Bombesin is an amidated tetradecapeptide originally purified from the skin of the European Frog . GRP replicates most of the bombesin’s biological effects in mammals . NMB is another mammalian bombesin-like peptide, but its most favorite receptor is the NMB receptor (NMBR) …”

“…GRP replicates most of the bombesin's biological effects in mammals. 4 NMB is another mammalian bombesin-like peptide, but its most favorite receptor is the NMB receptor (NMBR). 5 GRPR is a guanine nucleotide-binding protein coupled receptor (GPCR) coupling to the Gαq protein.…”
