In situ hybridization analysis of vasopressin gene transcription in the paraventricular and supraoptic nuclei of the rat: Regulation by stress and glucocorticoids

Herman, James P.·1995·Journal of Comparative Neurology

Abstract

Hypothalamic arginine vasopressin-containing neurons are prime elements in central circuits regulating the hypothalamo-pituitary-adrenocortical stress response. It is known that release and synthesis of vasopressin are cued by stressful stimuli. The present study was designed to assess effects of stress on vasopressin transcription and mRNA expression in defined populations of vasopressin neurons in the hypothalamic paraventricular (PVN) and supraoptic (SON) nuclei. Intron- and exon-directed in situ hybridization analyses were used to examine stress regulation of vasopressin heteronuclear (hn) gene transcription and mRNA levels. Actions of glucocorticoids on vasopressin induction were tested using adrenalectomized rats implanted with subcutaneous pellets delivering a constant, physiological dose of corticosterone. Pellet implantation into adrenalectomized rats allows for normal pituitary-adrenal tone in the absence of the ability to mount glucocorticoid stress responses. Elevation of vasopressin heteronuclear (hn) RNA in the medial parvicellular PVN was observed in both normal and adrenalectomized-corticosterone replaced rats as early as 30 minutes after stress initiation. In control rats, vasopressin hnRNA levels returned to baseline by 120 minutes. In contrast, vasopressin hnRNA remained elevated 120 minutes post-restraint in adrenalectomized-corticosterone replaced rats, indicating that the glucocorticoid stress response acts to rapidly inhibit vasopressin transcription.

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.
