| abstractText | The effect of a lack of the gene encoding monoamine oxidase A (MAO A) in transgenic Tg 8 mice on the corticosterone response to restraint, cold, water deprivation-induced, or social acute stress as well as chronic variable stress was studied. It was found that Tg 8 mice with genetic MAO A knockout and wild-type C3H/HeJ (C3H) strain showed similar plasma corticosterone resting level. MAO A knockout mice differed from C3H mice by attenuated response to restraint (60 min), cold (4 degrees C, 60 min), and water deprivation (48 h) as well as to a chronic (15 days) variable stress. No difference between Tg 8 and C3H strains in the response to psychosocial stress (encounters for 30 min of six previously isolated mice) has been found. ACTH administration to dexamethasone-pretreated mice produced a similar corticosterone effect in Tg 8 and C3H mice, indicating that the decreased stress response in MAO A-deficient mice was due rather to the central mechanisms regulating stress-induced ACTH release than to adrenocortical responsiveness to ACTH. |
