Abstract

Aims: There is mounting evidence that the transition metal copper may play an important role in the pathophysiology of Alzheimer's disease (AD). Triethylene tetramine dihydrochloride (trientine), a CuII-selective chelator, is a commonly used treatment for Wilson's disease to decrease accumulated copper, and thereby decreases oxidative stress. In the present study, we evaluated the effects of a 3-month treatment course of trientine (Trien) on amyloidosis in 7-month-old β-amyloid (Aβ) precursor protein and presenilin-1 (APP/PS1) double transgenic (Tg) AD model mice. Results: We observed that Trien reduced the level of advanced glycation end products (AGEs), and decreased Aβ deposition and synapse loss in brain of APP/PS1 mice. Importantly, we found that Trien blocked the receptor for AGEs (RAGE), downregulated β-site APP cleaving enzyme 1 (BACE1), inhibited amyloidogenic APP cleavage, and subsequently reduced Aβ levels. In vitro , in SH-SY5Y cells overexpressing Swedish mutant APP, Trien-mediated downregulation of BACE1 occurred via inhibition of the NF-κB signaling pathway. Innovation: In this study, we demonstrated for the first time that Trien inhibited amyloidogenic pathway including targeting the downregulation of RAGE and NF-κB. Conclusion: Trien might mitigate amyloidosis in AD by inhibiting the RAGE/NF-κB/BACE1 pathway. Our study demonstrates that Trien may be a viable therapeutic strategy for the intervention and treatment of AD and other AD-like pathologies. Antioxid. Redox Signal . 19, 2024–2039.

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

  • RAGEs are significantly or markedly expressed in many areas of the brain, such as the cortex, hippocampus, cerebellum, and substantia nigra, during the development of neurodegenerative diseases.

    “Similar to AGEs, RAGEs are significantly or markedly expressed in many areas of the brain, such as the cortex, hippocampus, cerebellum, and substantia nigra105–107 during the development of neurodegenerative diseases.”
  • Accumulation of AGEs and the AGE-RAGE interaction greatly induce reactive gliosis and the NF-κB proinflammatory pathway, leading to cellular stress, activated gliosis, and eventually neuronal degeneration.

    “Additionally, the accumulation of AGEs and the AGE-RAGE interaction greatly induce reactive gliosis and the NF-κB proinflammatory pathway, leading to cellular stress, activated gliosis, and eventually neuronal degeneration105.”

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.
