Metallothionein and the biology of aging

Open access
Swindell, William R.·2011·Ageing Research Reviews

Abstract

Metallothionein (MT) is a low molecular weight protein with anti-apoptotic properties that has been demonstrated to scavenge free radicals in vitro. MT has not been extensively investigated within the context of aging biology. The purpose of this review, therefore, is to discuss findings on MT that are relevant to basic aging mechanisms and to draw attention to the possible role of MT in pro-longevity interventions. MT is one of just a handful of proteins that, when overexpressed, has been demonstrated to increase mouse lifespan. MT also protects against development of obesity in mice provided a high fat diet as well as diet-induced oxidative stress damage. Abundance of MT is responsive to caloric restriction (CR) and inhibition of the insulin/insulin-like signaling (IIS) pathway, and elevated MT gene expression has been observed in tissues from fasted and CR-fed mice, long-lived dwarf mice, worms maintained under CR conditions, and long-lived daf-2 mutant worms. The dysregulation of MT in these systems is likely to have tissue-specific effects on aging outcomes. Further investigation will therefore be needed to understand how MT contributes to the response of invertebrates and mice to CR and the endocrine mutations studied by aging researchers.

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

  • Resiliency and biosynthetic genes were also differentially expressed between LRCs and nonLRCs, with known longevity factor Mt2 and protein translation components Pfdn5 and Eef1g enriched in LRCs.

    “Resiliency and biosynthetic genes were also differentially expressed, with known longevity factor (Swindell, 2011) Mt2 and protein translation components Pfdn5 and Eef1g enriched in LRCs.”
  • Two of the top differentially expressed genes between aged and young MuSCs are associated with increases in longevity.

    “Two of the top differentially expressed genes are associated with increases in longevity (Ladiges et al., 2009; Swindell, 2011).”

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.
