A 41-residue peptide purified as a corticotropin-releasing factor/beta-endorphin-releasing factor (CRF) in vitro was tested for its ability to stimulate the secretion of ACTH, beta-endorphin, and corticosterone in three animal groups: 1) unanesthesized rats bearing indwelling venous cannulae, 2) rats pretreated with chloropromazine plus morphine sulfate plus pentobarbital (CPZ-MS-Nb, and 3) rats with hypothalamic deafferentiations in the frontal and lateral retrochiasmatic areas. In all three bioassays iv administration of 0.1-10 micrograms CRF elicited a dose-related increase in plasma ACTH and beta-endorphin values over a 5- to 15-min period. Corticosterone secretion was also elevated but responded maximally with all doses of CRF tested. Pretreatment of CPZ-MS-Nb animals with 20 micrograms dexamethasone 4 h before assay abolished the CRF-induced hormone secretion. These data suggest that CRF may play a physiological role in the regulation of the hypothalamic-pituitary-adrenal axis.
