Acute administration of
corticotropin-releasing factor
(
CRF
) results in anorexic and
sympathomimetic
effects that suggest efficacy in chronic models of energy balance. The present studies employed a broad spectrum energy balance indices in lean and genetically obese Zucker rats in order to fully characterize the pharmacological efficacy of
CRF
and a
CRF
binding protein (CRF-BP) ligand inhibitor,
CRF
(6-33), which is thought to liberate
CRF
from CRF-BP. Acute administration of
CRF
(6-33) significantly increased
CRF
(2) receptor density by 10% within the ventromedial hypothalamic (VMH) nucleus of Zucker lean rats and decreased density by 10% in Zucker obese rats. A single infusion of
CRF
(6-33) increased nonshivering thermogenesis by 25-30% as measured by proton conductance in brown adipose tissue of both lean and obese rats. Chronic
CRF
(6-33) infusion suppressed body weight gain and elevated core temperature irrespective of genotype while increasing motor activity in obese rats without altering heart rate or blood pressure. Taken together, these results document strain-dependent, long-term effects of a CRF-BP ligand inhibitor on a select subset of physiological and behavioral measures of increased energy expenditure.
