Molecular Basis of the ‘Anti-Aging' Effect of Spermidine and Other Natural Polyamines - A Mini-Review

Minois, Nadège·2014·Gerontology

Abstract

Background: Spermidine, a naturally occurring polyamine, has recently emerged as exhibiting anti-aging properties. Its supplementation increases lifespan and resistance to stress, and decreases the occurrence of age-related pathology and loss of locomotor ability. Its mechanisms of action are just beginning to be understood. Objectives: An up-to-date overview of the so far identified mechanisms of action of spermidine and other polyamines on aging is presented. Methods: Studies of aging and of the molecular effects of polyamines in general and spermidine in particular are used to synthesize our knowledge on what molecular mechanisms spermidine and other polyamines trigger to positively affect aging. Results: Autophagy is the main mechanism of action of spermidine at the molecular level. However, recent research shows that spermidine can act via other mechanisms, namely inflammation reduction, lipid metabolism and regulation of cell growth, proliferation and death. It is suggested that the main pathway used by spermidine to trigger its effects is the MAPK pathway. Conclusions: Given that polyamines can interact with many molecules, it is not surprising that they affect aging via several mechanisms. Many of these mechanisms discovered so far have already been linked with aging and by acting on all of these mechanisms, polyamines may be strong regulators of aging.

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

  • Both HDAC10 and spermidine promote cellular survival through autophagy.

    “Both HDAC10 and spermidine are known to promote cellular survival through autophagy.”
  • Spermidine is a key factor in autophagy; increased levels of endogenous or exogenous spermidine induce autophagy and extend lifespan in a variety of cell types, including human immune cells.

    “The polyamine spermidine is also a key factor in autophagy and increased levels of endogenous or exogenous spermidine induce autophagy and extend lifespan in a variety of cell types, including human immune cells3637.”

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.
