Abstract

Which scientist has never heard of glutathione (GSH)? This well-known low-molecular-weight tripeptide is perhaps the most famous natural antioxidant. However, the interest in GSH should not be restricted to its redox properties. This multidisciplinary review aims to bring out some lesser-known aspects of GSH, for example, as an emerging tool in nanotechnologies to achieve targeted drug delivery. After recalling the biochemistry of GSH, including its metabolism pathways and redox properties, its involvement in cellular redox homeostasis and signaling is described. Analytical methods for the dosage and localization of GSH or glutathiolated proteins are also covered. Finally, the various therapeutic strategies to replenish GSH stocks are discussed, in parallel with its use as an addressing molecule in drug delivery.

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

  • Glutathione is a natural tripeptide (γ-l-glutamyl-l-cysteinylglycine) with a fundamental role in the regulation of redox homeostasis.

    “Glutathione is a natural tripeptide, that is γ-l-glutamyl-l-cysteinylglycine, harbouring a fundamental role in the regulation of redox homeostasis [176].”
  • Both GSH levels and the GSH/GSSG ratio are tightly controlled through regulation of synthesis, metabolism, transport, and degradation.

    “Being the main intracellular antioxidant buffer, both the levels of GSH and GSH/GSSH ratio are tightly controlled through a fine regulation of their synthesis, metabolism, transport, and degradation [176,177].”
  • GSH levels can be used as a biomarker for the oxidative status of the cell.

    “As GSH levels can be used as a biomarker for the oxidative status of the cell [176,181,182,183]”

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.
