Abstract

Glycogen synthase kinase-3 (GSK-3) regulates multiple cellular processes, and its dysregulation is implicated in the pathogenesis of diverse diseases. In this paper we will focus on the dysfunction of GSK-3 in Alzheimer's disease and Parkinson's disease. Specifically, GSK-3 is known to interact with tau, β-amyloid (Aβ), and α-synuclein, and as such may be crucially involved in both diseases. Aβ production, for example, is regulated by GSK-3, and its toxicity is mediated by GSK-induced tau phosphorylation and degeneration. α-synuclein is a substrate for GSK-3 and GSK-3 inhibition protects against Parkinsonian toxins. Lithium, a GSK-3 inhibitor, has also been shown to affect tau, Aβ, and α-synuclein in cell culture, and transgenic animal models. Thus, understanding the role of GSK-3 in neurodegenerative diseases will enhance our understanding of the basic mechanisms underlying the pathogenesis of these disorders and also facilitate the identification of new therapeutic avenues.

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

  • Suppression of Aβ42 toxicity supports previous reports in cell, mouse and fly models in which Aβ42 induces GSK-3β activity and inhibition or reduction of GSK-3β ameliorates Aβ42-induced degeneration.

    “Suppression of Aβ42 toxicity supports previous reports in cell, mouse and fly models in which Aβ42 induces GSK-3β activity and inhibition or reduction of GSK-3β ameliorates Aβ42-induced degeneration, either independent of or in concert with tau toxicity (99–101).”

    From Functional genomic screen and network analysis reveal novel modifiers of tauopathy dissociated from tau phosphorylation (2011) · cites this paper as [101]

    Section 2.2 (β-Amyloid; page unavailable) reports that Aβ activates GSK-3β in hippocampal cultures and that inhibiting GSK-3β prevents Aβ-induced neuronal toxicity; it also describes protective effects of GSK-3 deactivation in mouse models. The copy does not establish these findings specifically for Aβ42 across cell, mouse, and fly models, and it does not report a fly model. (LLM, conf=0.86)

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.
