“…E and NE can be differentially released from the adrenal, depending on splanchnic nerve stimulation frequency. Whereas NE is the main hormone secreted during LF stimulation (1-5 Hz) in cat 31,41 , our results in mouse are in favour of a preferential E secretion at both LF and HF stimulation. The same is observed in rat 15 and dog 35 .…”

“…In addition, the specie, collection technique and stimulation protocols varied from one study to the other, thus precluding trivial quantitative comparison. Basal and splanchnic nerve stimulation-evoked release of adrenal catecholamines has been directly measured in adrenal-venous blood only in a few cases, in the cat 30,31 , rat 15,23,32,33 and dog 34,35 but not in the mouse. Our in vivo data indicate a basal E:NE ratio close to 10:1 in the mouse.…”

“…In addition, hybridization was seen over cells in the pancreas (data not shown). Although it has been previously reported (Gaumann et al, 1989) that PYY-immunoreactive material is present in the adrenal medulla, no specific PYY hybridization was detected anywhere in the adrenal gland (Fig. 5E).…”

“…Broome et al (I 985) and Ekman et al (1986) have proposed that PYY occurs in the CNS, based on immunohistochemical and RIA data. The occurrence of PYYlike immunoreactivity in sympathetic neurons (Happola et al, 1990) and the adrenal gland (Gaumann et al, 1989) has also been reported. Tatemoto (1989) has suggested that a novel member of the NPY family may be expressed in the brain.…”

Differential expression of mRNAs for neuropeptide Y-related peptides in rat nervous tissues: possible evolutionary conservation

et al. 1992

Neuropeptide Y (NPY) is the only member of its peptide family that has been isolated from the mammalian CNS. We have recently found that two different NPY-related molecules are present in the CNS of a cyclostome, the river lamprey (Lampetra fluviatilis) (Soderberg et al., 1991). Here we show that this is also true for the rat CNS, by demonstrating expression of peptide YY (PYY) mRNA in brainstem neurons distinct from those neurons that express NPY mRNA. Dissimilar oligonucleotide DNA probes complementary to 3' untranslated regions of the rat PYY, NPY, and pancreatic polypeptide (PP) mRNA were used in in situ hybridization experiments on sections of rat brain and spinal cord, visceral organs, and peripheral nerve ganglia. The PYY probe hybridized with two populations of neurons in the brainstem: one dispersed along the midline in the rostral medulla and another in the lateral caudal medulla (A1 region). No additional labeling was detected in the remainder of the neuraxis. In the periphery, PYY hybridization was seen only in endocrine cells of the colon, and not in sympathetic ganglia or the adrenal gland, suggesting that previous observations of PYY immunoreactivity in these latter structures were due to antibody cross- reactivity with NPY. The NPY probe did not hybridize with cells on the midline region that contains PYY neurons, but it did label large numbers of neurons throughout the neuraxis. No expression of PP mRNA was detected in the CNS. Northern blot analysis failed to detect PYY mRNA in the CNS, further supporting the observation that PYY is only expressed by a discrete collection of CNS neurons. The anatomy of PYY- and NPY-expressing cells in the CNS and gut shows a striking similarity between rat and lamprey (Brodin et al., 1989), vertebrates that diverged evolutionarily about 450 million years ago, suggesting that both peptide systems have been conserved throughout vertebrate evolution.
