    Long-term effects of chronic antioxidant stress are not well-researched. Safe levels of antioxidant consumption have yet to be established in human diets. The lack of overall awareness of the subject has invoked comparatively few clinical or field studies, sparse data and statistics, and may suggest a valuable field of nutritional research has ...

    In E.coli, negative autoregulation of SoxS protein serves as a dampening mechanism for the soxRS redox stress response. [3] SoxRS regulon genes can be regulated by additional factors. [2] At least three known genes including xthA and katE are regulated by a sigma factor, KatF, whose synthesis is turned on during the stationary phase. XthA ...

  7. Hormesis - Wikipedia

    en.wikipedia.org/wiki/Hormesis

    Hormesis is a biological phenomenon where a low dose of a potentially harmful stressor, such as a toxin or environmental factor, stimulates a beneficial adaptive response in an organism. In other words, small doses of stressors that would be damaging in larger amounts can actually enhance resilience, stimulate growth, or improve health at lower ...
