Social behavior deficits in the Fmr1 mutant mouse

Abstract

Mice exhibiting deficits in social behavior may provide valuable models for autistic-like behavioral problems. We tested social interactions in male mice from three inbred strains: C57BL/6J (B6), BALB/cJ (C) and DBA/2J (D2). All three strains showed gradual habituation of the number of social interactions with an ovariectomized female over four subsequent 2min sessions, returning to initial levels when presented with another stimulus mouse. Next, we studied males with a knockout mutation in the Fmr1 gene on a B6 background. KO animals showed strongly reduced levels of social interaction, which were about similar as those of habituated controls. This social behavior deficit suggests that Fmr1 KO mice could possibly be used as models for autistic behaviors.

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?

  • Fmr1 KO mice, compared to wild-type, have lower than normal levels of initial social interactions, fail to show a preference for social novelty, and display inappropriate social responses.

    “Fmr1 KO, in comparison to the wild-type (WT) strain, are described as having lower than normal levels of initial social interactions (Mineur et al., 2006), fail to show a preference for social novelty, and display inappropriate social responses (Pietropaolo et al., 2011).”
  • Fmr1 KO mice exhibit abnormal social interactions, including a general reduction in social contact and a failure to show social recognition.

    “Fmr1 KO also exhibit abnormal social interactions, including a general reduction in social contact and a failure to show social recognition (Bernardet and Crusio, 2006; Mineur et al., 2006; Spencer et al., 2005; Yan et al., 2004).”

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.
