Abstract

The transcription factor NF-κB, a central regulator of immunity, is subject to regulation by redox changes. We now report that cysteine-179 of the inhibitory κB kinase (IKK) β-subunit of the IKK signalosome is a central target for oxidative inactivation by means of S-glutathionylation. S-glutathionylation of IKK-β Cys-179 is reversed by glutaredoxin (GRX), which restores kinase activity. Conversely, GRX1 knockdown sensitizes cells to oxidative inactivation of IKK-β and dampens TNF-α-induced IKK and NF-κB activation. Primary tracheal epithelial cells from Glrx1 -deficient mice display reduced NF-κB DNA binding, RelA nuclear translocation, and MIP-2 (macrophage inflammatory protein 2) and keratinocyte-derived chemokine production in response to LPS. Collectively, these findings demonstrate the physiological relevance of the S-glutathionylation–GRX redox module in controlling the magnitude of activation of the NF-κB pathway.

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

  • The IKK complex is a core component of NF-κB and a target of ROS, affecting NF-κB and S-glutathionylation and inhibited IKKβ activity.

    “In addition, I-κB-Kinase (IKK) complex is the core component of NF-κB and is a target of ROS, affecting thus NF-κB and S-glutathionylation and inhibited IKKβ activity (Reynaert et al. 2006).”

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.
