The Keap1-Nrf2 System: A Mediator between Oxidative Stress and Aging

Open access

Abstract

Oxidative stress, a term that describes the imbalance between oxidants and antioxidants, leads to the disruption of redox signals and causes molecular damage. Increased oxidative stress from diverse sources has been implicated in most senescence‐related diseases and in aging itself. The Kelch‐like ECH‐associated protein 1‐ (Keap1‐) nuclear factor‐erythroid 2‐related factor 2 (Nrf2) system can be used to monitor oxidative stress; Keap1‐Nrf2 is closely associated with aging and controls the transcription of multiple antioxidant enzymes. Simultaneously, Keap1‐Nrf2 signaling is also modulated by a more complex regulatory network, including phosphoinositide 3‐kinase (PI3K)/protein kinase B (Akt), protein kinase C, and mitogen‐activated protein kinase. This review presents more information on aging‐related molecular mechanisms involving Keap1‐Nrf2. Furthermore, we highlight several major signals involved in Nrf2 unbinding from Keap1, including cysteine modification of Keap1 and phosphorylation of Nrf2, PI3K/Akt/glycogen synthase kinase 3 β , sequestosome 1, Bach1 , and c ‐ Myc . Additionally, we discuss the direct interaction between Keap1‐Nrf2 and the mammalian target of rapamycin pathway. In summary, we focus on recent progress in research on the Keap1‐Nrf2 system involving oxidative stress and aging, providing an empirical basis for the development of antiaging drugs.

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.
