Abstract

Protein thiols are an important component of mammalian intramitochondrial antioxidant defenses owing to their selective interaction with reactive oxygen and nitrogen species (ROS and RNS). Reversible modifications of protein thiols resulting from these interactions are also an important aspect of redox signal transduction. Therefore, to assess how mitochondria respond to oxidative stress and act as nodes in redox signaling pathways, it is important to measure general changes to protein thiol redox states and also to identify the specific mitochondrial thiol proteins involved. Here we outline some of the approaches that can be used to accomplish these goals and thereby infer the multiple roles of mammalian mitochondrial protein thiols in antioxidant defense and redox signaling.

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.
