BACKGROUND Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin closely reflects vasopressin release. Copeptin has been shown to subtly mirror stress potentially mediated via corticotrophin-releasing hormone. To further test a potential direct interaction of corticotrophin-releasing hormone with copeptin release, which could augment vasopressin effects on pituitary function, we ...

Corticotrophin-releasing hormone is a key regulator of the mammalian stress response. Although its actions on behavior are well documented, the actions of corticotrophin-releasing hormone in cortical neuronal systems are poorly understood. In the present experiments, adult male Sprague-Dawley rats were anesthetized and field excitatory post-synaptic potential recordings were made from sensorimo...

BACKGROUND Preterm birth accounting approximate 10% of pregnancies in women is a tremendous social, clinical and economic burden. However, its underlying causes remain largely unknown. Emerging evidence suggests that endocannabinoid signaling via cannabinoid receptor CB1 play critical roles in multiple early pregnancy events in both animals and humans. Since our previous studies demonstrated th...

There is a growing body of experimental and clinical evidence to indicate that stress influences gastrointestinal motility. The most common pattern of gastrointestinal motor alterations induced by a variety of different stress factors is that of delayed gastric emptying and accelerated colonic transit. Central administration of corticotrophin releasing factor mimics both of these effects. This ...

Leptin and corticotrophin-releasing factor increase sympathetic nervous activity to interscapular brown adipose tissue, kidneys, and adrenal glands. Leptin is known to increase hypothalamic corticotrophin-releasing factor. In this study, we tested the hypothesis that leptin-dependent increases in sympathetic nervous activity are mediated through increases in central nervous system corticotrophi...

Nine normal volunteers and 15 patients with pituitary disorders were given a combined test of anterior pituitary function using four hypothalamic releasing factors and arginine vasopressin. Rapid sequential intravenous infusions of human corticotrophin releasing factor 100 micrograms, growth hormone releasing factor 100 micrograms, luteinising hormone releasing hormone 100 micrograms, and thyro...
