Altered levels of β-endorphin fragments after chronic morphine treatment of guinea-pig ileum in vivo and in vivo [PDF]

, 1980
The isolated myenteric plexus-longitudinal muscle of the guinea-pig ilem (GPI) was used as testsystem to study the influence of chronic morphine treatment on the levels of enkephalins, β-endorphin and some of its fragments.

Low-frequency electroacupuncture exerts antinociceptive effects through activation of POMC neural circuit induced endorphinergic input to the periaqueductal gray from the arcuate nucleus

Molecular Pain
It has been widely recognized that electroacupuncture (EA) inducing the release of β-endorphin represents a crucial mechanism of EA analgesia. The arcuate nucleus (ARC) in the hypothalamus is a vital component of the endogenous opioid peptide system ...

β-Endorphin-induced prolactin secretion is mediated by suppression of release of newly synthesized hypothalamic dopamine

, 1980
Intracisternal administration of synthetic human β-endorphin in rats increased plasma prolactin. This effect of β-endorphin is blocked completely by parenteral administration of the dopamine receptor agonist, apomorphine.

Electrical Stimulation-Induced Release of β-Endorphin from Genetically Modified Neuro-2a Cells

Cell Transplantation, 2008
The quantity of therapeutic gene products released from genetically engineered cells can be controlled externally at different levels. The widely used approach of controlling expression, however, generally has the disadvantage that chemical substances ...

Brain beta-endorphin concentrations in experimental chronic liver disease

, 1982
β-Endorphin, Met-enkephalin, substance P and somatostatin concentrations have been evaluated in brain areas of rats with severe liver disease obtained by chronic pretreatment with CCl4 for 3 or 9 weeks.

Effects of α-endorphin, β-endorphin and (des-tyr1)-γ-endorphin on α-MPT-induced catecholamine disappearance in discrete regions of the rat brain

, 1979
Summary Following the intracerebroventricular administration of α-endorphin, β-endorphin and (des-tyrosine1)-γ-endorphin in a dose of 100 ng, the α-MPT-induced catecholamine disappearance was found to be altered in discrete regions of the rat brain.

β-Endorphin Response to Endurance Exercise: Relationship to Exercise Dependence

, 1993
Considerable research has shown significant increases in β-endorphin levels after aerobic activity. These increases and their accompanying euphoric effect have been suggested as a possible psychophysiological mechanism underlying the exercise-dependence

State-dependent modulation of feeding behavior by proopiomelanocortin-derived β-endorphin

, 2003
Feeding behavior can be divided into appetitive and consummatory phases, differing in neural substrates and effects of deprivation. Opioids play an important role in the appetitive aspects of feeding, but they also have acute stimulatory effects on food ...

A novel delta opioid receptor specific peptide reduces craving in an animal model of cocaine seeking

Addiction Neuroscience
Substance use disorder, and particularly cocaine use disorder, is a complex disease that affects societal, economic, and psychological factors. Endogenous β-endorphin released after prolonged cocaine withdrawal has been reported to activate the accumbal ...
