Abstract

We used in situ hybridization histochemistry with synthetic oligodeoxyribonucleotide probes to identify cells that synthesize mRNAs encoding tyrosine hydroxylase in the mesencephalon and substance P, enkephalin, and dynorphin in the rat forebrain. Dopaminergic cells in the mesencephalon project to the forebrain and influence neuropeptide levels. We examined the effect of unilateral 6-hydroxydopamine lesions (which eliminated tyrosine hydroxylase mRNA-containing cells in the mesencephalon) on substance P, enkephalin, and dynorphin mRNA levels. Substance P mRNA levels were depressed, whereas enkephalin mRNA levels were elevated in consecutive sections from striatal areas in all animals. The effects of the lesions on dynorphin mRNA levels were less robust, and considerable variation between animals was observed. Changes were evident in the levels of message in individual cells but not in the numbers of labeled cells. These effects were not uniform throughout the dopamine-innervated areas, suggesting degrees of control not apparent with RNA blot-hybridization or dot-blot analyses.

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.
