  • Title: Beta-endorphin processing in pituitary and brain is sensitive to haloperidol stimulation.
    Author: Ham J, Smyth DG.
    Journal: Neuropeptides; 1985 Feb; 5(4-6):497-500. PubMed ID: 3158837.
    Abstract:
    Chronic administration of haloperidol (1 mg/Kg) into rats led to a marked increase in the level of beta-endorphin related peptides in the pars intermedia and brain stem. Using a combination of ion-exchange chromatography and radioimmunoassay, the increase in beta-endorphin under haloperidol treatment was confined to the acetylated derivatives: alpha,N-acetyl beta-endorphin 1-26, alpha,N-acetyl beta-endorphin 1-27 and alpha,N-acetyl beta-endorphin 1-31; there was no change in the level of the NH2-peptides. Haloperidol had no effect on the beta-endorphin related peptides in the anterior pituitary or hypothalamus. These findings suggest that haloperidol can influence not only the level of beta-endorphin related peptides in pituitary and brain, but also their posttranslational processing, possibly serving to regulate the level of biologically active beta-endorphin 1-31.
