Abstract

Multiple lines of evidence implicate the serotonin (5-HT) system in social function, including biomarker findings in autism spectrum disorder. In mice, knock-in of a rare Gly56Ala substitution in the serotonin transporter (SERT) causes elevated whole blood 5-HT levels, increased 5-HT clearance in the brain, and altered social and repetitive behavior. To further examine the molecular impact of this variant on social response, SERT Ala56 mutant mice and wildtype littermate controls were exposed to a social or non-social stimulus. We examined the differential activation of the prefrontal cortex, lateral amygdala, and medial amygdala, to social stimuli through RNA sequencing. Differentially expressed genes were enriched in axonal guidance signaling pathways, networks related to nervous system development and function, neurological and psychiatric disorders, and behavior. These identified pathways and networks may shed light on the molecular cascades underlying the impact of altered SERT function on social behavior.

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.
