Abstract/OtherAbstract:
The anoretic effect of corticotropin-releasing factor (CRF) was not dependent on adrenal activation in goldfish (Carassius auratus). Moreover, an interaction between CRF and the hypothalamic catecholaminergic system in the central regulation of food intake was observed. The intracerebroventricular (icv) administration of CRF increased cortisol levels and reduced food intake and hypothalamic norepinephrine and dopamine content at 2 hr postinjection, with these effects reversed by alpha-helical CRF[9-41] pretreatment. The anoretic effect of CRF was independent of the circulating cortisol increase, because it was only evoked after icv injections but not after intraperitoneal (ip) administration. Furthermore, the increase in plasma cortisol levels induced by ip administration of this steroid did not modify feeding.
