Abstract

Nrf2 is a transcription factor that promotes antioxidant and drug-metabolizing gene expression. It also regulates the transcription of genes involved in carbohydrate and lipid metabolism, NADPH regeneration, and heme and iron metabolism, as well as proteasome metabolism. Emerging research has identified Nrf2 as a critical factor for promoting survival of mammalian cells subjected to ionizing radiation. At a mechanistic level, Nrf2 promotes the repair of DNA damage and drives detoxification of superoxide that is generated hours to days after irradiation. This review summarizes research in these areas and discusses targeting of Nrf2 in radiation-resistant cancer and Nrf2׳s role in mitigating acute radiation syndrome.

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.
