Abstract

Conditional loss of BACE1 in adult mouse brain results in abnormalities in the hippocampal mossy fiber pathway, which is important for learning and memory.

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

  • BACE1fl/fl mice were previously generated and provided by R.V.

    “BACE1fl/fl mice (C57BL/6-Bace1tm1.1mrl) were previously generated and provided by R.V. [36].”

    From Selective suppression of oligodendrocyte-derived amyloid beta rescues neuronal dysfunction in Alzheimer’s disease (2024) · cites this paper as [36]

    The Results section ('Generation and characterization of conditional BACE1 knockout mice'; page unavailable) states that BACE1fl/fl mice were generated, and Materials and Methods ('Animals'; page unavailable) describes how. R.V. is an author of the cited paper, but our copy does not say that he provided the mice to the citing researchers. (LLM, conf=0.83)

  • Tamoxifen administration between the ages of 4 and 8 weeks, after the majority of developmental myelination has taken place, avoids developmental and early postnatal effects of BACE1 knockout on myelin.

    “To avoid developmental and early postnatal effects of BACE1 knockout on myelin [34], we used tamoxifen inducible Cre lines, with tamoxifen administered between the ages of 4 and 8 weeks (after the majority of developmental myelination has taken place [35]), according to standard protocols [36].”
  • Conditional BACE1 deletion in neurons feature axon guidance defects.

    “In addition, conditional BACE1 deletion in neurons feature axon guidance defects [644]”
  • Axon guidance abnormalities in the hippocampus persist in adult conditional BACE1 knockout, confirming an important role for BACE1 in adult circuitry architecture as well as developmental functions.

    “Intriguingly, axon guidance abnormalities in the hippocampus persist in the adult conditional KO of BACE1, confirming an important role of the secretase in adult circuitry architecture as well as its established developmental functions (69,72–74).”

    From The β-Secretase BACE1 in Alzheimer’s Disease (2021) · cites this paper as [72]

  • BACE1 cleavage of CHL1 produces an intracellular membrane-bound C-terminal fragment that influences cytoskeleton dynamics and leads to growth cone collapse upon Sema3A.

    “BACE1 cleavage yields an intracellular membrane-bound C-terminal fragment of CHL1 that is able to influence cytoskeleton dynamics, leading to growth cone collapse on presentation of the Sema3A cue.”

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.
