Abstract

Exposure to environmental toxins is associated with a variety of age-related diseases including cancer and neurodegeneration. For example, in Parkinson's disease (PD), chronic environmental exposure to certain toxins has been linked to the age-related development of neuropathology. Neuronal damage is believed to involve the induction of neuroinflammatory events as a consequence of glial cell activation. Cellular senescence is a potent anti-cancer mechanism that occurs in a number of proliferative cell types and causes the arrest of proliferation of cells at risk of malignant transformation following exposure to potentially oncogenic stimuli. With age, senescent cells accumulate and express a senescence-associated secretory phenotype (SASP; that is the robust secretion of many inflammatory cytokines, growth factors and proteases). Whereas cell senescence in peripheral tissues has been causally linked to a number of age-related pathologies, little is known about the induction of cellular senescence and the SASP in the brain. On the basis of recently reported findings, we propose that environmental stressors associated with PD may act in part by eliciting senescence and the SASP within non neuronal glial cells in the ageing brain, thus contributing to the characteristic decline in neuronal integrity that occurs in this disorder.

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

  • Diseases associated with the accumulation of senescent cells, such as neurodegenerative disorders, osteoarthritis and idiopathic pulmonary fibrosis, exhibit iron dyshomeostasis, where iron burden often correlates with disease severity.

    “Diseases associated with the accumulation of senescent cells, such as neurodegenerative disorders (e.g. Alzheimer's and Parkinson's) [20], [21], [22], osteoarthritis [23], [24] and idiopathic pulmonary fibrosis [25], also exhibit iron dyshomeostasis where often iron burden correlates with disease severity [14], [15], [26], [27], [28], [29], [30], [31], [32], [33], [34].”

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.
