Abstract

Mutations in presenilin 1 and 2 ( PS1 and PS2 ) cause autosomal dominant familial Alzheimer’s disease (FAD). Ferroptosis has been implicated as a mechanism of neurodegeneration in AD since neocortical iron burden predicts Alzheimer’s disease (AD) progression. We found that loss of the presenilins dramatically sensitizes multiple cell types to ferroptosis, but not apoptosis. FAD causal mutations of presenilins similarly sensitizes cells to ferroptosis. The presenilins promote the expression of GPX4, the selenoprotein checkpoint enzyme that blocks ferroptosis by quenching the membrane propagation of lethal hydroperoxyl radicals. Presenilin γ-secretase activity cleaves Notch-1 to signal LRP8 expression, which then controls GPX4 expression by regulating the supply of selenium into the cell since LRP8 is the uptake receptor for selenoprotein P. Selenium uptake is thus disrupted by presenilin FAD mutations, suppressing GPX4 expression. Therefore, presenilin mutations may promote neurodegeneration by derepressing ferroptosis, which has implications for disease-modifying therapeutics.

  • LRP8 has been recently shown to affect ferroptosis by regulating the level of selenoprotein GPX4 in cancer cells.

    “LRP8 has been recently shown to affect ferroptosis by regulating the level of selenoprotein GPX4 in cancer cells (54–56).”

    From Secreted Apoe rewires melanoma cell state vulnerability to ferroptosis (2024) · cites this paper as [55]

    The Results section (‘LRP8 suppression markedly sensitizes cells to ferroptosis’; page not provided) reports that LRP8 overexpression increased GPX4 protein and improved resistance to ferroptosis. But the experiments described here used hippocampal neuron cells and mouse embryonic fibroblasts, not cancer cells, so the cancer-cell qualifier is unsupported by this source. (LLM, conf=0.88)

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.
