Antidepressant drug action in a transgenic mouse model of the endocrine changes seen in depression

Pepin, M C, Pothier, F, Barden, N·1992·Molecular Pharmacology

Abstract

We have created transgenic mouse lines with impaired glucocorticoid receptor function by expression of a type II glucocorticoid receptor antisense RNA in brain tissues. These animals have endocrinological characteristics similar to those seen in depression, including a hyperactive hypothalamic-pituitary-adrenal axis as indicated by elevated plasma corticosterone and adrenocorticotropin hormone levels. Treatment of transgenic animals with the tricyclic antidepressant desipramine increased hypothalamic glucocorticoid receptor mRNA concentration and dexamethasone-binding activity while decreasing plasma adrenocorticotropin hormone concentration and corticosterone levels. These results support the hypothesis that antidepressants exert action on the hypothalamic-pituitary-adrenal axis through modulation of glucocorticoid receptor gene expression.

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.
