One of the three major groups of endogenous opioid peptides. They are large peptides derived from the PRO-OPIOMELANOCORTIN precursor. The known members of this group are alpha-, beta-, and gamma-endorphin. The term endorphin is also sometimes used to refer to all opioid peptides, but the narrower sense is used here; OPIOID PEPTIDES is used for the broader group.
A 90-amino acid peptide derived from post-translational processing of pro-opiomelanocortin (POMC) in the PITUITARY GLAND and the HYPOTHALAMUS. It is the C-terminal fragment of POMC with lipid-mobilizing activities, such as LIPOLYSIS and steroidogenesis. Depending on the species and the tissue sites, beta-LPH may be further processed to yield active peptides including GAMMA-LIPOTROPIN; BETA-MSH; and ENDORPHINS.
An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
Peptides with the ability to stimulate pigmented cells MELANOCYTES in mammals and MELANOPHORES in lower vertebrates. By stimulating the synthesis and distribution of MELANIN in these pigmented cells, they increase coloration of skin and other tissue. MSHs, derived from pro-opiomelanocortin (POMC), are produced by MELANOTROPHS in the INTERMEDIATE LOBE OF PITUITARY; CORTICOTROPHS in the ANTERIOR LOBE OF PITUITARY, and the hypothalamic neurons in the ARCUATE NUCLEUS OF HYPOTHALAMUS.
Pituitary Hormones, Anterior
A 30-kDa protein synthesized primarily in the ANTERIOR PITUITARY GLAND and the HYPOTHALAMUS. It is also found in the skin and other peripheral tissues. Depending on species and tissues, POMC is cleaved by PROHORMONE CONVERTASES yielding various active peptides including ACTH; BETA-LIPOTROPIN; ENDORPHINS; MELANOCYTE-STIMULATING HORMONES; and others (GAMMA-LPH; CORTICOTROPIN-LIKE INTERMEDIATE LOBE PEPTIDE; N-terminal peptide of POMC or NPP).
Low hot pain threshold predicts shorter time to exercise-induced angina: results from the psychophysiological investigations of myocardial ischemia (PIMI) study. (1/492)OBJECTIVES: The purpose of this study was to test whether cutaneous thermal pain thresholds are related to anginal pain perception. BACKGROUND: Few ischemic episodes are associated with angina; symptoms have been related to pain perception thresholds. METHODS: A total of 196 patients with documented coronary artery disease underwent bicycle exercise testing and thermal pain testing. The Marstock test of cutaneous sensory perception was administered at baseline after 30 min of rest on two days and after exercise and mental stress. Resting hot pain thresholds (HPTs) were averaged for the two baseline visits and divided into two groups: 1) average HPT <41 degrees C, and 2) average HPT > or =41 degrees C, to be clearly indicative of abnormal hypersensitivity to noxious heat. RESULTS: Patients with HPT <41 degrees C had significantly shorter time to angina onset on exercise testing than patients with HPT > or =41 degrees C (p < 0.04, log-rank test). Heart rates, systolic blood pressure and rate-pressure product at peak exercise were not different for the two groups. Resting plasma beta-endorphin levels were significantly higher in the HPT <41 degrees C group (5.9+/-3.7 pmol/liter vs. 4.7+/-2.8 pmol/liter, p = 0.02). Using a Cox proportional hazards model, patients with HPT <41 degrees C had an increased risk of angina (p = 0.03, rate ratio = 2.0). These differences persisted after adjustment for age, gender, depression, anxiety and history of diabetes or hypertension (p < 0.01). CONCLUSIONS: Occurrence of angina and timing of angina onset on an exercise test are related to overall hot pain sensory perception. The mechanism of this relationship requires further study. (+info)
Enhancing effects of beta-endorphin on glutamate neurotoxicity. (2/492)AIM: To study the effect of beta-endorphin (beta-End) on monosodium glutamate (MSG)-induced neurotoxicity (GNT). METHODS: Image analysis of neuronal areas and determination of mitochondrial membrane protein-bound Ca2+ and intracellular free Ca2+ ([Ca2+]i) were used. RESULTS: beta-End aggravated MSG-induced neuronal injury in arcuate nucleus of hypothalamus in a dose-dependent manner in the range from 0.5 to 5.0 mg.kg-1. MSG-induced increase in mitochondrial membrane protein-bound Ca2+ was enhanced when treated with beta-End 2 g.L-1. MSG-induced elevation in [Ca2+]i in single neuron was also augmented from 320 +/- 84 to 589 +/- 78 nmol.L-1 by the treatment with beta-End 2 g.L-1. CONCLUSION: beta-End enhanced GNT via aggravating the disruption of intracellular Ca2+ homeostasis induced by MSG. (+info)
Physiological changes in Pachinko players; beta-endorphin, catecholamines, immune system substances and heart rate. (3/492)Pachinko is a popular form of recreation in Japan. However, in recent years, along with Pachinko's popularity, "Pachinko dependence" has become topical news. The purpose of this study was to investigate beta-endorphin, catecholamines, immune system responses and heart rate during the playing of Pachinko. The following significant results were observed. (1) Plasma concentration of beta-endorphin increased before playing Pachinko and while in the Pachinko-center (p < 0.05). (2) Beta-endorphin and norepinephrine increased when the player began to win (i.e. at "Fever-start") compared to baseline (p < 0.05). (3) Beta-endorphin, norepinephrine and dopamine increased when the winning streak finished (i.e. at "Fever-end") compared to baseline (p < 0.05-0.01). (4) Norepinephrine increased past 30 minutes after "Fever-end" compared to baseline (p < 0.05). (5) Heart rate increased before "Fever-start" compared to baseline, peaked at "Fever-start" and rapidly decreased to match rates measured at rest. But the increase was observed from 200 seconds after "Fever-start" (p < 0.05-0.001). (6) There was a positive correlation between the number of hours subjects played Pachinko in a week and the differences between beta-endorphin levels at "Fever-start" and those at rest (p < 0.05). (7) The number of T-cells decreased while the number of NK cells increased at "Fever-start" compared to baseline (p < .05). These results suggest that intracerebral substances such as beta-endorphin and dopamine are involved in the habit-forming behavior associated with Pachinko. (+info)
Effect of raised plasma beta endorphin concentrations on peripheral pain and angina thresholds in patients with stable angina. (4/492)OBJECTIVE: To determine whether changes in plasma concentrations of beta endorphins alter angina threshold and peripheral pain threshold in patients with stable angina. DESIGN: Latin square design comparison of angina thresholds by exercise treadmill test and peripheral pain thresholds using a radiant heat source in eight patients with stable angina under control conditions, after stimulation of pituitary beta endorphin release by ketoconazole, after suppression of pituitary beta endorphin release by dexamethasone, and after blockade of opioid receptors by intravenous naloxone. RESULTS: An approximately fivefold increase in circulating concentrations of beta endorphins was found after administration of ketoconazole (mean (SEM): 13.9 (1.2) v 73.8 (6.2) pg/ml; p < 0.05), which was associated with an increase in peripheral pain threshold to a radiant heat source (time to onset of pain perception 72 (19) v 123 (40) seconds; p < 0.05), but no significant difference in angina threshold. A reduction in circulating concentrations of beta endorphins after pretreatment with dexamethasone was statistically non-significant (13.9 (1.2) v 9.0 (1.5) pg/ml; NS) and was not associated with any change in either peripheral pain or angina thresholds. No effects were seen after blockade of opioid receptors by previous administration of intravenous naloxone. CONCLUSIONS: Increased plasma concentrations of beta endorphins alter peripheral pain threshold but not angina threshold in patients with stable angina pectoris. (+info)
The interaction of bioactive peptides with an immobilized phosphatidylcholine monolayer. (5/492)The interaction of three bioactive peptides, bombesin, beta-endorphin, and glucagon with a phosphatidylcholine monolayer that was immobilized to porous silica particles and packed into a stainless steel column cartridge, has been studied using dynamic elution techniques. This immobilized lipid monolayer provides a biophysical model system with which to study the binding of peptides to a lipid membrane. In particular, the influence of temperature and methanol concentration on the affinity of each peptide for the immobilized lipid surface was assessed. For all test peptides, nonlinear retention plots were observed at all temperatures that contrasted sharply with the simple linear plots observed for the small unstructured control molecules N-acetyltryptophanamide and diphenylalanine. An analysis of the thermodynamics of the interaction of peptides with the immobilized monolayer was also carried out. The results revealed that while the peptides interacted with the monolayer predominantly through hydrophobic interactions, the relative contribution of DeltaH(assoc)(O) and DeltaS(assoc)(O) to the overall free energy of association was dependent on the temperature and methanol concentration. In particular, it was evident that under most conditions, the binding of the peptides to the immobilized lipid monolayer was enthalpy-driven, i.e., mediated by nonclassical hydrophobic interactions. Significant band-broadening and asymmetric and split peaks were also observed for bombesin, beta-endorphin, and glucagon at different temperatures and methanol concentrations. These changes in affinity and peak shape are consistent with the formation of multiple conformational species during the interaction of these peptides with the lipid monolayer. In addition, the binding behavior of the three test peptides on an n-octylsilica surface that lacked the phospho headgroups of the phospholipid was significantly different from that observed with the immobilized phosphatidylcholine surface, indicating a specificity of interaction between the peptides and the lipid surface. Overall, these experimental results demonstrate that the biomimetic phosphatidylcholine monolayer provides a stable and sensitive system with which to explore the molecular mechanism of peptide conformational changes during membrane interactions.

The stress response of the gilthead sea bream (Sparus aurata L.) to air exposure and confinement. (6/492)We investigated short-term effects (up to 24 h) of air exposure and confinement, and long-term effects (up to 11 days) of confinement, to elucidate signalling pathways in the stress response of gilthead sea bream Sparus aurata L. Plasma glucose and lactate were taken as indicators of sympathetic activation, and alpha-melanocyte stimulating hormone (alpha-MSH), adrenocorticotrophic hormone (ACTH) and cortisol as indicators of activation of the brain-pituitary-interrenal (BPI) axis. Air exposure for 3 min resulted, within 30 min, in an increase in plasma concentrations of cortisol, alpha-MSH, glucose, lactate, osmolality and plasma Na, Cl and Mg. Plasma ACTH and beta-endorphin and plasma K, Ca and P did not change. We conclude that air exposure mainly activates the brain-sympathetic-chromaffin cell (BSC) axis. In fish confined at a density of 70 kg/m(3) (compared with 4 kg/m(3) in controls), cortisol, ACTH and alpha-MSH increased within 1 h, indicating activation of the BPI axis. Plasma glucose, Na, Cl and Mg increased with an 8 h delay compared with the response to air exposure. No changes in plasma lactate, osmolality, K, Ca and P were observed. Long-term confinement induced a biphasic cortisol response with peaks at 1 h and at 2 and 3 days. A gradual increase in plasma beta-endorphin concentrations peaked at 7 days; the concentration of alpha-MSH increased rapidly within 1 h and then declined to control values 4 days after the onset of confinement. No changes in ACTH were detected. Our data provide evidence that a stressor-specific activation of the BSC and BPI axes may occur in Sparus aurata. (+info)
Strenuous resistive breathing induces proinflammatory cytokines and stimulates the HPA axis in humans. (7/492)Interleukin-1beta (IL-1beta) and interleukin-6 (IL-6), powerful stimulants of the hypothalamic-pituitary-adrenal (HPA) axis, increase in response to whole body exercise. Strenuous inspiratory resistive breathing (IRB), a form of clinically relevant "exercise" for the respiratory muscles, produces beta-endorphin through a largely unknown mechanism. We investigated (in 11 healthy humans) whether strenuous IRB produces proinflammatory cytokines and beta-endorphin in parallel with stimulation of the HPA axis, assessed by concurrent measurement of ACTH. Subjects underwent either severe [at 75% of maximal inspiratory pressure (P(m) (max))] or moderate (at 35% of P(m) (max)) IRB. Plasma cytokines, beta-endorphin, and ACTH were measured at rest (point R), at the point at which the resistive load could not be sustained (point F), and at exhaustion [15 min later (point E)]. During severe IRB, IL-1beta increased from 0.83 +/- 0.12 pg/ml at point R to 1.88 +/- 0. 53 and 4.06 +/- 1.27 pg/ml at points F and E, respectively (P < 0. 01). IL-6 increased from 5.30 +/- 1.02 to 10.33 +/- 2.14 and 11.66 +/- 2.29 pg/ml at points F and E, respectively (P = 0.02). ACTH and beta-endorphin fluctuated from 20.87 +/- 5.49 and 25.03 +/- 3.97 pg/ml at point R to 22.97 +/- 4.41 and 26.32 +/- 3.93 pg/ml, respectively, at point F and increased to 46.96 +/- 8.55 and 40.32 +/- 5.94 pg/ml, respectively, at point E (P < 0.01, point E vs. point F). There was a positive correlation between the IL-6 at point F and the ACTH and beta-endorphin at point E (r = 0.88 and 0.94, respectively; P < 0.01) as well as between the increase in IL-6 (between points R and F) and the increases in ACTH and beta-endorphin (between points F and E, r = 0.91 and 0.92, respectively; P < 0.01). Moderate IRB did not produce any change. We conclude that severe IRB produces proinflammatory cytokines and stimulates the HPA axis in humans secondary to the production of cytokines (especially IL-6). (+info)
Localization of pro-opiomelanocortin mRNA transcripts and peptide immunoreactivity in rat heart. (8/492)OBJECTIVE: alpha-Melanocyte-stimulating hormone (alpha-MSH), beta-endorphin and other pro-opiomelanocortin-(POMC) derived peptides have been detected in the heart, but it is uncertain whether they are synthesized by cardiomyocytes or by cardiac nerves innervating the heart. The objective of this study was to determine whether POMC peptides are synthesized by cardiomyocytes. METHODS: Pro-opiomelanocortin peptides were localized in rat heart by immunohistochemistry using antisera against alpha-MSH, beta-endorphin and alpha N-acetyl-beta-endorphin, the predominant POMC peptides found in heart. Pro-opiomelanocortin mRNA was investigated by reverse transcription polymerase chain reaction (RT-PCR) using primers that discriminate between full-length POMC mRNA and a 5' truncated POMC transcript that is presumed to be non-functional. RESULTS: alpha-Melanocyte-stimulating hormone, beta-endorphin and alpha N-acetyl-beta-endorphin immunoreactivities were localized in atrial myocytes, particularly in the atrial appendages, but not to a significant extent in ventricular myocytes. Cardiac nerves were not immunostained. Atrial natriuretic peptide (ANP) immunoreactivity was similarly distributed in the adult heart. In neonatal heart, POMC-peptide and ANP immunoreactivities were present in both atrial and ventricular myocytes. RT-PCR amplification showed that full-length POMC mRNA transcripts were present in both atrial and ventricular tissue and provide evidence that 5' truncated POMC mRNA is expressed in heart. CONCLUSIONS: These results support the hypothesis that cardiomyocytes synthesize POMC peptides. (+info)
