Abstract

Alzheimer's disease (AD) is characterized by progressive memory loss accompanied by synaptic and neuronal degeneration. Although research has shown that substantial neurodegeneration occurs even during the early stages of AD, the detailed mechanisms of AD pathogenesis are largely unknown because of difficulties in diagnosis and limitations of the analytical methods. The 5XFAD mouse model harbors five early-onset familial AD (FAD) mutations and displays substantial amyloid plaques and neurodegeneration. Here, we use quantitative mass spectrometry to identify proteome-wide changes in the 5XFAD mouse hippocampus during the early stages of AD pathology. A subset of the results was validated with immunoblotting. We found that the 5XFAD mice display higher expression of ApoE, ApoJ (clusterin), and nicastrin, three important proteins in AD that are known to participate in amyloid-β processing and clearance, as well as the neurological damage/glial marker protein GFAP and other proteins. A large subset of the proteins that were up- or downregulated in 5XFAD brains have been implicated in neurological disorders and cardiovascular disease, suggesting an association between cardiovascular disease and AD. Common upstream regulator analysis of upregulated proteins suggested that the XBP1, NRF2, and p53 transcriptional pathways were activated, as was IGF-1R signaling. Protein interactome analysis revealed an interconnected network of regulated proteins, with two major sub-networks centered on AβPP processing membrane complexes and mitochondrial proteins. Together with a recent study on the transcriptome of 5XFAD mice, our study allows a comprehensive understanding of the molecular events occurring in 5XFAD mice during the early stages of AD pathology.

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

  • LCM has been used to micro-dissect neurons from both fresh frozen human brain and formalin-fixed paraffin embedded tissue sections for proteomic analyses.

    “LCM has been used to micro-dissect neurons from both fresh frozen human brain and formalin-fixed paraffin embedded tissue sections for proteomic analyses [144, 145].”
  • Hong et al. (2013) demonstrated activation of the NRF2 transcriptional pathway in 5XFAD mice at four months of age.

    “For instance, Hong et al. (2013) used proteomic analysis to demonstrate activation of the NRF2 transcriptional pathway in 5XFAD mice at four months of age [100], which is consistent with ARE activation in Alzheimer’s patients [101].”

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.
