Genetic Analysis of Cytoprotective Functions Supported by Graded Expression of Keap1
Open accessAbstract
Keap1 regulates Nrf2 activity in response to xenobiotic and oxidative stresses. Nrf2 is an essential regulator of cytoprotective genes. Keap1-null mice are lethal by weaning age due to malnutrition caused by severe hyperkeratosis of the upper digestive tract. Analysis of Keap1::Nrf2 double mutant mice revealed that currently recognizable phenotypes of Keap1-null mice are all attributable to constitutive activation of Nrf2. We previously reported that hepatocyte-specific Keap1 knockout (Keap1(flox/-)::Albumin-Cre) mice are viable and more resistant to acute toxicity of acetaminophen (APAP). In the current study, we found that the floxed Keap1 allele is hypomorphic and that Keap1 expression was decreased in all examined tissues of Keap1(flox/-) mice. Taking advantage of the hypomorphic phenotype of Keap1(flox/-) mice, we examined the effects of graded reduction of Keap1 expression in adult mice. When challenged with APAP, Keap1(flox/-) mice were more protected from mortality than wild-type and even Keap1(flox/-)::Albumin-Cre mice. In contrast, a decrease in Keap1 levels to less than 50% resulted in increased mortality in a study of 2-year-old mice. These results support our contention that the benefits of Nrf2 activation in acute toxicity are hormetic and that constitutive Nrf2 activation beyond a certain threshold is rather disadvantageous to long-term survival.

“Although Nrf2 itself has been shown to be a critical component of cancer chemoprevention (2, 33), recent studies have also revealed a strong association of constitutive activation of Nrf2 due to somatic mutations of KEAP1 and the NRF2 gene and carcinogenesis (30, 32, 34, 36).”

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.
