Steady state levels of pro-dynorphin-related end products in the striatum and substantia nigra of the adult rhesus monkey
(Elsevier, 1985)
Analysis of an acid extract of the striatum of the rhesus monkey revealed that the molar ratio of dynorphin A(1-8)-sized material and dynorphin (A(1-17)-sized material is approximately 1:1. In addition, the molar ratios ...
Some of the [alpha]-NH2-acetylated [beta]-endoprhin-like material in rat and monkey pituitary and brain is acetylated [alpha]- and [beta]-endorphin
(Elsevier, 1983)
There are several studies demonstrating the existence of [alpha]-NH2-acetylated (N-Ac) forms of [beta]-endorphin in the intermediate lobe of several species (1,4,6). These include N-Ac-[beta]-endorphin(1-31), N-Ac-[beta] ...
Paradoxical effect of corticosteroids on pituitary ACTH/[beta]-endorphin release in stressed animals
(Elsevier, 1988)
We have previously demonstrated a number of changes in the anterior lobe proopiomelanocortin (POMC) system in chronically stressed rats. The purpose of the present experiments was to investigate whether chronically stressed ...
Behavioral effects of dynorphin1-13 in the mouse and rat: Initial observations
(Elsevier, 1980)
Dynorphin is a recently identified, pharmacologically potent endogenous opioid peptide. Heretofore it has not been characterized for its behavioral effects. The effects of centrally infused dynorphin upon a variety of ...
[D-Ala2,(F5)Phe4]-dynorphin1-13-NH2 (DAFPHEDYN): A potent analog of dynorphin 1-13
(Elsevier, 1987)
Intracerebroventricular administration of the dynorphin analog, [D-Ala2,(F5)Phe4]-dynorphin1-13-NH2 (DAFPHEDYN) in rats produced diuresis and profound analgesia. Both effects were antagonized by central administration of ...
Gamma-melanotropin response to ovine corticotropin releasing factor in normal humans
(Elsevier, 1987)
Plasma [gamma]-melanotropin was measured by a [gamma]3MSH-specific radioimmunoassay before and after a single bolus intravenous infusion of ovine corticotropin releasing factor (oCRF; 0.1 ug/kg) in seven normal men. A ...
Localization of neurons containing pro-opiomelanocortin-related peptides in the hypothalamus and midbrain of the lizard, Anolis carolinensis evidence for region-specific processing of [beta]-endorphin
(Elsevier, 1984-12-24)
Immunohistochemical analyses of the lizard brain, following colchicine pretreatment, revealed two populations of POMC-producing cell bodies located in medial-basal hypothalamus and the mesencephalic tegmentum. Analyses of ...
Pharmacological and anatomical evidence of selective [mu], [delta], and [chi] opioid receptor binding in rat brain
(Elsevier, 1986-12-03)
While the distribution of opioid receptors can be differentiated in the rat central nervous system, their precise localization has remained controversial, due, in part, to the previous lack of selective ligands and insensitive ...
Tritiated ethylketocyclazocine binding in rat brain: Differential distribution of binding sites across brain regions
(Elsevier, 1982-09)
In rat brain, 3H-EKC shows a relative regional distribution of binding which parallels that of 3H-morphine. Dynorphin(1-13) has a pattern similar to morphine and dissimilar to EKC in displacing the three labels. Dynorphin(1-13) ...
Characterization of the forms of [beta]-endorphin and [alpha]-MSH in the caudal medulla of the rat and guinea pig
(Elsevier, 1986-07-09)
The post-translational processing of pro-opiomelanocortin (POMC) in brain remains controversial. Classically, there was thought to be a single cell group in the arcuate nucleus with long projections through limbic structures. ...
