Abstract

There is increasing evidence that GABAergic system plays an important role in the neural control of learning and memory processes. GAT1 over-expressing mice (NA) were generated, in which GAT1 is under the control of a neuron-specific enolase (NSE) promoter, to investigate effects of GABA transporter on cognitive function. Our results revealed that NA mice displayed cognitive deterioration in associative learning ability and new object recognition retention, compared with the wild-type littermates (WT2). However, the impaired cognitive function of transgenic mice could be rescued after chronic administration of GAT1 selective inhibitor for 6 days. In addition, there was no change of the expression of NMDA receptors in NA mice. Taken together, we show a potentially important role for GAT1 in the neural control of cognitive processes, and indicate great potential for GAT1 as a clinical target of cognitive disorders.

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

  • Reducing hippocampal GABA levels impairs learning and memory.

    “Furthermore, reducing hippocampal GABA levels impairs learning and memory [120, 121], and silencing inhibitory interneurons in the dentate gyrus prevents both encoding of new memories and recall of old memories [122].”

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.
