Activation of topoisomerase II-mediated excision of chromosomal DNA loops during oxidative stress

Hydrogen peroxide (H(2)O(2)), a reactive oxygen species (ROS), is known to induce oxidative stress and apoptosis. U937 cells treated with H(2)O(2) were shown to produce high molecular weight (HMW) DNA fragments ∼50 to 100 kb in size in <1 min. The formation of these HMW DNA fragments is reversibl...
