Stress‐induced hyperphosphorylation of tau in the mouse brain

Okawa, Yasuhiro, Ishiguro, Koichi, Fujita, Shinobu C·2003·FEBS Letters

Abstract

We previously showed that starvation causes reversible hyperphosphorylation of tau in the mouse brain. To explore possible involvement of stress in tau hyperphosphorylation quantitative analysis of phosphorylated tau in four brain regions of mice subjected to cold water stress (CWS) was made by immunoblot analyses using phosphorylation‐dependent antibodies directed to eight sites on tau known to be hyperphosphorylated in the brain of Alzheimer's disease (AD) patients. Ser199, Ser202/Thr205, Thr231/Ser235 were hyperphosphorylated 20 and 40 min after CWS. The response was pronounced in the hippocampus and cerebral hemisphere, but weak in the cerebellum in parallel with the regional vulnerability in AD. Among the regulatory phosphorylation of protein kinases studied, a transient phosphorylation of tau protein kinase I/glycogen synthase kinase 3β at Ser9 was most conspicuous.

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?

  • Stress exposure increases the phosphorylation of tau in animal studies.

    “Intriguingly, animal studies have shown that stress exposure increases the phosphorylation of tau142.”
  • Rodent studies have shown that glucocorticoids and stress increase tau phosphorylation and cognitive deficits, and PHF-tau immunoreactivity in opiate user brains is significantly higher than in age-matched controls.

    “Rodent studies have shown that glucocorticoids and stress increase tau phosphorylation and cognitive deficits [75, 144, 173], and PHF-tau immunoreactivity in opiate user brains is significantly higher than in age-matched controls [4].”

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.
