Abstract

We studied a mouse model of the haploinsufficiency form of Rubinstein-Taybi syndrome (RTS), an inheritable disorder caused by mutations in the gene encoding the CREB binding protein (CBP) and characterized by mental retardation and skeletal abnormalities. In these mice, chromatin acetylation, some forms of long-term memory, and the late phase of hippocampal long-term potentiation (L-LTP) were impaired. We ameliorated the L-LTP deficit in two ways: (1) by enhancing the expression of CREB-dependent genes, and (2) by inhibiting histone deacetyltransferase activity (HDAC), the molecular counterpart of the histone acetylation function of CBP. Inhibition of HDAC also reversed the memory defect observed in fear conditioning. These findings suggest that some of the cognitive and physiological deficits observed on RTS are not simply due to the reduction of CBP during development but may also result from the continued requirement throughout life for both the CREB co-activation and the histone acetylation function of CBP.

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

  • Other monogenic syndromes like Kleefstra, KBG, WitKoS, Angelman, Coffin-Sirris, Rubinstein-Taybi, Phelan-McDermid, Smith-Magenis Syndrome and Kabuki syndrome also have a clear prefrontal component in their behavioral and cognitive phenotype.

    “Other monogenic syndromes like Kleefstra, KBG, WitKoS, Angelman, Coffin-Sirris, Rubinstein-Taybi, Phelan-McDermid, Smith–Magenis Syndrome and Kabuki syndrome also have a clear prefrontal component in their behavioral and cognitive phenotype [272–280].”

    From Development of prefrontal cortex (2022) · cites this paper as [272]

    The section on CBP+/− mice as a model for Rubinstein–Taybi syndrome (p. 8) describes short attention spans and difficulty planning and executing motor acts, supporting the behavioral aspect of the claim for that syndrome. It does not establish a prefrontal component; the same passage says future studies are needed to identify the brain regions involved. This citation is assessed for Rubinstein–Taybi syndrome, not the other syndromes covered by the citation range. (LLM, conf=0.84)

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.
