Abstract

A mouse model for Down syndrome, Ts1Cje, has been developed. This model has made possible a step in the genetic dissection of the learning, behavioral, and neurological abnormalities associated with segmental trisomy for the region of mouse chromosome 16 homologous with the so-called “Down syndrome region” of human chromosome segment 21q22. Tests of learning in the Morris water maze and assessment of spontaneous locomotor activity reveal distinct learning and behavioral abnormalities, some of which are indicative of hippocampal dysfunction. The triplicated region in Ts1Cje, from Sod1 to Mx1 , is smaller than that in Ts65Dn, another segmental trisomy 16 mouse, and the learning deficits in Ts1Cje are less severe than those in Ts65Dn. In addition, degeneration of basal forebrain cholinergic neurons, which was observed in Ts65Dn, was absent in Ts1Cje.

  • These same populations of basal forebrain neurons typically develop less severe atrophy in Ts1Cje and Ts65Dn-App+/+/− mice or older ages compared with age-matched Ts65Dn mice.

    “These same populations of basal forebrain neurons typically develop less severe atrophy in the Ts1Cje (Sago et al., 1998) and Ts65Dn-App ϩ/ϩ/Ϫ mice (our unpublished observation) or older ages compared with that occurring in age-matched Ts65Dn mice.”

    The Discussion reports that at six months, basal forebrain cholinergic neurons were normal in number and size in Ts1Cje mice, unlike the loss and size decrease seen in Ts65Dn mice. This supports the comparison for Ts1Cje at that age, but the paper does not establish that Ts1Cje neurons develop atrophy or address the comparison at older ages. The sentence attributes the Ts65Dn-App observation to unpublished work, not to Sago et al. (LLM, conf=0.82)

  • Ts65Dn and Ts1Cje mice survive to adulthood and exhibit morphological, biochemical, and transcriptional changes seen in human DS.

    “Two segmental trisomy mouse models of DS, Ts65Dn (Davisson et al., 1990), and Ts1Cje (Sago et al., 1998) mice, survive to adulthood and exhibit a number of the morphological, biochemical, and transcriptional changes seen in the human disease (Davisson et al., 1990;Reeves et al., 1995;Holtzman et al., 1996).”
  • Ts1Cje mice do not develop BFCN atrophy and degeneration, and they have less severe learning and behavioral deficits than Ts65Dn mice.

    “These mice do not develop BFCN atrophy and degeneration, and they have less severe learning and behavioral deficits than Ts65Dn mice (Sago et al., 1998).”

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.
