Silver foxes from a commercial population (farm bred or unselected for behavior control) and from populations selected for tame behavior and enhanced aggressiveness towards man have been investigated. Plasma cortisol and adrenocorticotropic hormone (ACTH) levels, pituitary ACTH levels, POW gene expression in the anterior pituitary, and corticotropin-releasing factor (CRF) gene expression in the hypothalamus were assessed. The results indicate that the males from the tame-behavior group have lower plasma cortisol and ACTH levels and POW gene expression in the anterior pituitary in response to capture and handling in comparison with unselected ones. Foxes from the aggressive behavior group also have lower POW expression, although plasma cortisol and ACTH levels remain the same as in unselected ones. The three groups of animals show no significant changes in the ACTH level in the pituitary and CRY expression in the hypothalamus. (C) 2004 Elsevier Inc. All rights reserved.
