Hormesis is an adaptive stress response implicated in longevity regulation. Schroeder et al. (2013) have now connected stress, epigenetic changes, and aging in yeast by showing that mitochondria-derived reactive oxygen species modulate the chromatin binding capacity of the histone demethylase Rph1p at subtelomeres, resulting in lifespan extension.
胁迫反应是一种与长寿调控有关的适应性应激反应。Schroeder 等人（2013 年）通过证明线粒体来源的活性氧调节着端粒处组蛋白去甲基酶 Rph1p 的染色质结合能力，从而延长酵母的寿命，将应激、表观遗传变化和衰老联系起来。
