Widespread expression of functional D1-dopamine receptors in fetal rat brain

Shearman, Lauren P, Zeitzer, Jamie, Weaver, David R·1997·Developmental Brain Research

Abstract

Maternal treatment with cocaine or the D1-dopamine receptor agonist, SKF 38393, induces expression of the immediate-early gene, c-fos, in fetal rodent brain. Our previous studies have focused on the suprachiasmatic nucleus late in gestation. In the present report, we examined the anatomical distribution of functional D1-dopamine receptors throughout fetal rat brain. Functional D1 receptors were defined using three complementary methods: in situ hybridization to detect D1 receptor mRNA, autoradiographic detection of 125I-SCH 23982 binding, and in situ hybridization to detect c-fos gene expression induced by maternal treatment with SKF 38393. D1-dopamine receptor binding, receptor mRNA, and SKF 38393-induced c-fos gene expression are widespread in fetal brain by late gestation. These data indicate that the fetal brain is sensitive to dopamine receptor activation, and suggest that gestational exposure to drugs of abuse acting via dopaminergic mechanisms may influence fetal brain function.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SKF 38,393 is a D1-receptor agonist that induces c-Fos protein in several brain areas, including the amygdala and BST, within an hour following a systemic infusion.

  • In humans, melatonin and dopamine receptors appear as early as gestational week 18 in the fetal SCN, suggesting melatonin and dopamine may serve as the primary communicators of circadian information for the fetus.

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.
