Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...
Increase in delta, but not mu, receptors in MSG-treated rats
(Elsevier, 1982-09)
Neonatal treatment of rats with Monosodium Glutamate (MSG) has been demonstrated to destroy cell bodies of neurons in the arcuate nucleus including the brain beta-endorphin (B-END) system. The effects on opiate receptors ...
Peptide F (pro-enkephalin fragment) : Radioimmunoassay, and stress-induced changes in adrenal
(Elsevier, 2006-04-07)
Utilizing a nine amino-acid (Asp-Glu-Leu-Tyr-Pro-Leu-Glu-Val-Glu) non-enkephalin containing fragment of Peptide F from the pro-enkephalin molecule, a radioimmunoassay was developed. Extraction of bovine, rat, and guinea ...
Plasma beta-endorphin-like immunoreactivity, self reported pain perception and anxiety levels in women during pregnancy and labor
(Elsevier, 2006-04-07)
Plasma Beta-endorphin (B-END) immunoreactivity was measured in 19 men, 16 women at midcycle, and ten pregnant women at various points in their pregnancies. There is a significant difference between the levels measured in ...
Pulse-chase studies of the POMC/Beta-endorphin system in the pituitary of acutely and chronically stressed rats
(Elsevier, 2006-04-07)
Experiments were carried out to determine whether stress induces biochemical changes in the pro-opiomelanocortin (POMC) system in anterior (AL) and intermediate-posterior lobe (IPL) of rat. In a series of pulse-chase ...
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] ...
Dynorphin is located throughout the CNS and is often co-localized with alpha-neo-endorphin
(Elsevier, 2006-04-07)
The opioid peptide dynorphin has been described as widely distributed in CNS when measured by RIA. Our previous immunohistochemical studies have only demonstrated dynorphin cells as those containing AVP. We now report the ...
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) ...
[3H] dynorphin binding to guinea pig and rat brain
(Elsevier, 1983)
[3H] Dynorphin can be shown to bind to the brains of both rat and guinea pigs with approximately 50% specific binding. Characterization of the binding in terms of multiple opiate receptor types supports the kappa selectivity ...
Processing of prodynorphin by the prohormone convertase PC1 results in high molecular weight intermediate forms : Cleavage at a single arginine residue
(Elsevier, 1994-01-03)
Processing of rat prodynorphin (proDyn) by the mouse prohormone convertase PCI was investigated. Recombinant vaccinia virus vectors were used to coexpress proDyn and PC1 in rat PC12 pheochromocytoma and mouse AtT-20 ...
