Abstract

Apolipoprotein E (ApoE) is the major genetic risk factor for Alzheimer's disease (AD). The ApoE4 allele is associated with earlier disease onset and greater cerebral deposition of the amyloid beta peptide (Abeta), the major constituent of senile (amyloid) plaques. The molecular mechanism underlying these effects of ApoE4 remains unclear; ApoE alleles could have different influences on Abeta production, extracellular aggregation, or clearance. Because the missense mutations on chromosomes 14 and 21 that cause familial forms of AD appear to lead to increased secretion of Abeta, it is important to determine whether ApoE4 has a similar effect. Here, we have examined the effects of all three ApoE alleles on the processing of betaAPP and the secretion of Abeta in intact cells. We established neural (HS683 human glioma) and non-neural (Chinese hamster ovary) cell culture systems that constitutively secrete both ApoE and Abeta at concentrations like those in human cerebrospinal fluid. betaAPP metabolites, generated in the presence of each ApoE allele, were analysed and quantified by two methods: immunoprecipitation and phosphorimaging, and ELISA. We detected no consistent allele-specific effects of ApoE on betaAPP processing in either cell type. Our data suggest that the higher amyloid burden found in AD subjects expressing ApoE4 is not due to increased amyloidogenic processing of betaAPP, in contrast to findings in AD linked to chromosome 14 or 21. These co-expressing cell lines wil…

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?

  • A previous in vitro study showed no effect of apoE isoforms on APP processing.

    “Overall, our results in PDAPP/TRE mice are consistent with a previous in vitro study showing no effect of apoE isoforms on APP processing (42).”
  • Others found no clear evidence for isoform-specific effects on APP processing.

    “However, others found no clear evidence for isoform-specific effects on APP processing (Biere et al., 1995; Cedazo-Minguez et al., 2001; Irizarry 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.
