Abstract

The members of the CRF peptide family, corticotropin-releasing factor (CRF), urocortin I (Ucn I), urocortin II (Ucn II) and urocortin III (Ucn III) coordinate endocrine and behavioral responses to stress. CRF has also been demonstrated to stimulate dopamine (DA) synthesis. In our study, a superfusion system was used to investigate the effects of this peptide family on striatal DA release following electrical stimulation. The involvement of the CRF receptors was studied by pretreatment of rat striatal slices with selective CRF antagonists. CRF and Ucn I increased the release of [(3)H]DA while Ucn II and Ucn III were ineffective. The CRFR1 antagonist antalarmin inhibited the [(3)H]DA release induced by electrical stimulation and enhanced by CRF and Ucn I. The CRFR2 antagonist astressin-2B was ineffective. These results suggest that CRF and Ucn I mediate DA release through the activation of CRFR1. Ucn II and Ucn III are not involved in this process.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
