Application

Astressin has been used as a CRF-receptor antagonist to study its effects on the decrease in the Schaffer collateral-CA1 field potential induced by hypoxia/hypoglycemia (ischemia) in rat hippocampal slices.

Biochem/physiol Actions

Astressin is a non-selective corticotropin releasing factor (CRF)-receptor antagonist. It potentially blocks CRF-induced adrenocorticotropic hormone (ACTH) release. Astressin effectively deceases delayed effects of chronic social isolation such as anxiety and fobial states in rats.

Peripheral activation of corticotropin-releasing factor receptor type 2 (CRF(2)) by urocortin 1, 2, or 3 (Ucns) exerts powerful effects on gastric function; however, little is known about their expression and regulation in the stomach. We investigated the expression of Ucns

Previous work in our laboratory has shown that Urocortin (Ucn), a peptide related to corticotropin releasing factor (CRF), injected into the basolateral nucleus of the amygdala (BLA) in male Wistar rats would result in an anxiogenic response as measured in

Corticosterone-releasing hormone (CRH) and arginine vasopressin (AVP) are crucial components of the hypothalamic-pituitary-adrenal axis that stimulates the release of adrenocorticotropic hormone from the pituitary and mediate the stress response. CRH binds to two subtypes of CRH receptors (CRH-R1 and CRH-R2)

Rapid eye movement sleep (REM) is increased after controllable stress (modeled by escapable footshock, ES) and decreased after uncontrollable stress (modeled by inescapable footshock, IS). Decreases in REM after IS are exacerbated by corticotropin releasing factor (CRF) and attenuated by

Corticotrophin-releasing factor (CRF) plays a major role in coordinating stress responses. We aimed to test whether blocking endogenous CRF activity can prevent the stress-induced dilation of intercellular spaces in esophageal mucosa. Eighteen adult male rats were divided into 3 groups:
