Abstract

We investigated whether endogenously or exogenously produced nitric oxide (NO) can inhibit cellular glutathione reductase (GR) via the formation of S‐nitrosothiols to decrease cellular glutathione (GSH) and increase oxidative stress in RAW 264.7 cells. The specificity of this inhibition was demonstrated by addition of a NO‐synthase inhibitor, and met‐ or oxyhemoglobin. Using isolated GR we found that only certain NO donors inhibit this enzyme via S‐nitrosothiol. Furthermore, we found that cellular GSH decrease is paralleled by an increase of superoxide anion production. Our results show that the GR enzyme is a potential target of S‐nitrosothiols to decrease cellular GSH levels and to induce oxidative stress in macrophages.

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.
