Effects of morphine treatment on pro-opiomelanocortin systems in rat brain
(Elsevier, 1990-06-11)
In previous studies to determine whether chronic opiate administration might negatively feedback upon endogenous opioid systems in the CNS, investigators found no changes in steady-state concentrations of opioid peptides ...
Immunocytochemical localization of pro-opiomelanocortin-derived peptides in the adult rat spinal cord
(Elsevier, 1986-07-16)
A dispersed descending pro-opiomelanocortin (POMC) fiber system has been demonstrated by peroxidase-antiperoxidase (PAP) immunocytochemistry in the adult rat spinal cord. [beta]-endorphin, adrenocorticotrophic hormone ...
Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
Proopiomelanocortin peptide immunocytochemistry in rhesus monkey brain
(Elsevier, 1984-12)
The immunocytochemical distribution of Proopiomelanocortin (POMC) peptides ([beta]-endorphin, ACTH, [alpha]-MSH, 16K fragment) was studied in the brain of the rhesus monkey (Macaca mulatta). Some animals were administered ...
Strategies for studying opioid peptide regulation at the gene, message and protein levels
(Elsevier, 1984)
Three opioid peptide precursors have been isolated and characterized in endocrine and nervous tissue: pro-opiomelanocortin, pro-enkephalin, and pro-dynorphin. Since each of those opioid peptide systems have been extensively ...
Short-Term Adrenalectomy Increases Glucocorticoid and Mineralocorticoid Receptor mRNA in Selective Areas of the Developing Hippocampus
(Elsevier, 1993-10)
In the central nervous system, adrenal steroids bind to two different types of corticosteroid receptors: glucocorticoid (GR) or mineralocorticoid (MR). In vitro biochemical and autoradiographic techniques have been used ...
Anatomical relationship between opioid peptides and receptors in rhesus monkey brain
(Elsevier, 1984-12)
To determine whether opioid peptide-receptor pharmacological associations found in vitro (e.g., enkephalin-[delta], dynorphin-[kappa]) predict anatomical relationships in situ, immunocytochemical and receptor autoradiographic ...
Inhibition of opiate tolerance by non-competitive receptor antagonists
(Elsevier, 1994-01-07)
Our laboratory and others have previously reported that the non-competitive (NMDA) receptor antagonist, MK-801, interferes with the development of tolerance to the analgesic effects of morphine. The present studies were ...
