Abstract

The cellular mechanisms which lead to the generation and pathological deposition of beta amyloid in Alzheimer's disease are unknown. In this report we describe the proteolytic processing of the amyloid precursor protein (APP) to an 11.5-kDa COOH-terminal derivative which contains the full-length beta amyloid sequence. This processing step normally occurs at low levels in parallel with APP maturation in the secretory pathway. Inhibition of oxidative energy metabolism by sodium azide or the mitochondrial uncoupler carbonyl cyanide m-chlorophenylhydrazone increased the proteolysis of APP to the 11.5-kDa derivative by about 80-fold with accumulation of this APP derivative in the Golgi complex. Agents which inhibit protein transport in the secretory pathway, including monensin and brefeldin A, also increased the production of the 11.5-kDa derivative. Inhibition of APP maturation demonstrated that the 11.5-kDa derivative could be produced by proteolysis of immature APP. These results demonstrate that APP processing to potentially amyloidogenic COOH-terminal derivatives occurs in either the endoplasmic reticulum or Golgi complex and can be modulated by the state of cellular energy metabolism. Deficits in oxidative energy metabolism have recently been found in the cerebral cortex of patients with Alzheimer's disease. These findings raise the possibility that energy-related metabolic stress may lead to altered metabolism of APP and contribute to amyloidosis in Alzheimer's disease.

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?

  • Mitochondria directly influence other AD-associated pathologies, particularly APP and Aβ homeostasis.

    “Data also argue mitochondria directly influence other AD-associated pathologies, and particularly APP and Aβ homeostasis.”
  • Whether Aβ changes precede either age-related or AD-related brain bioenergetic changes is less clear-cut.

    “Whether Aβ changes precede either age-related or AD-related brain bioenergetic changes is less clear-cut, especially since abundant data from human and cell-based studies either suggest or demonstrate bioenergetic factors regulate both APP processing and Aβ production [95–100].”

  • COX inhibition and ATP depletion both reduced non-amyloidogenic, α secretase-mediated APP processing in cell culture experiments.

    “This was directly demonstrated in cell culture experiments in which COX inhibition and ATP depletion both reduced non-amyloidogenic, α secretase-mediated APP processing [95, 96, 98].”

  • Bioenergetic metabolism affects APP processing and Aβ production.

    “Bioenergetic metabolism certainly affects APP processing and Aβ production.”

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.
