Abstract

Nrf2 (NF-E2-related factor 2) plays a key role in the protection of vertebrates against environmental stress by contributing to the inducible expression of detoxification and antioxidant enzymes. Keap1 (Kelch-like ECH-associated protein 1) is a sensor for oxidative and electrophilic stresses. Keap1 also acts as an E3 ubiquitin ligase substrate-recognition subunit that specifically targets Nrf2. Keap1 causes Nrf2 to be degraded through the ubiquitin-proteasome pathway and thus ensures that Nrf2 is constitutively suppressed under unstressed conditions. Upon exposure to oxidative or electrophilic stress, Keap1 loses its ability to ubiquitinate Nrf2. Many lines of evidence have recently clarified that the Keap1-Nrf2 system also plays critical roles in the maintenance of cellular homeostasis. One of the most salient examples is the contribution of Keap1-Nrf2 to metabolic and energy-balance regulation. In particular, how the Keap1-Nrf2 system protects the body against diabetes mellitus and how perturbations in this system provoke the disease condition are now under intense investigation. This review will summarize the recent progress made in this area.

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.
