Abstract

Many cases of early-onset inherited Alzheimer's disease (AD) are caused by mutations in the presenilin-1 (PS1) gene. PS1 mutations may perturb cellular Ca(2+) homeostasis and thereby render neurons vulnerable to excitotoxicity and apoptosis. We now report that PC12 cells expressing PS1 mutations and primary hippocampal neurons from PS1 mutant knockin mice exhibit greatly increased levels of ryanodine receptors (RyR) and enhanced Ca(2+) release following stimulation with caffeine. Double-labeling immunostaining and co-immunoprecipitation analyses indicate that PS1 and RyR are colocalized and interact physically. Caffeine treatment sensitizes neurons expressing mutant PS1 to apoptosis induced by amyloid beta-peptide, a neurotic peptide linked to the pathogenesis of AD. When taken together with recent evidence for alterations in RyR in brains of AD patients, our data suggest that PS1 mutations may promote neuronal degeneration in AD by increasing transcription and translation of RyR and altering functional properties of ryanodine-sensitive Ca(2+) pools.

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.
