Abstract

Apolipoprotein E4 (apoE4), one of the three common isoforms of apoE, has been implicated in Alzheimer's disease. The effects of apoE on neuronal growth were determined in cultures of dorsal root ganglion neurons. In the presence of beta-migrating very low density lipoproteins (beta-VLDL), apoE3 increased neurite outgrowth, whereas apoE4 decreased outgrowth. The effects of apoE3 or apoE4 in the presence of beta-VLDL were prevented by incubation with a monoclonal antibody to apoE or by reductive methylation of apoE, both of which block the ability of apoE to interact with lipoprotein receptors. The data suggest that receptor-mediated binding or internalization (or both) of apoE-enriched beta-VLDL leads to isoform-specific differences in interactions with cellular proteins that affect neurite outgrowth.

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?

  • APOE4 has been observed to exhibit enhanced receptor binding and/or signaling.

    “In contrast, APOE4 has been observed to exhibit enhanced receptor binding and/or signaling9,34.”
  • Most studies have shown that apoE3 augments neurite outgrowth to a greater extent than apoE4.

    “Most studies have shown that apoE3 augments neurite outgrowth to a greater extent than apoE4 (Bellosta et al., 1995; Nathan et al., 1994; Nathan et al., 2002; Sun et al., 1998; Teter et al., 1999).”

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.
