H2O2-induced higher order chromatin degradation: A novel mechanism of oxidative genotoxicity

GW Konat - Journal of biosciences, 2003 - Springer
The genotoxicity of reactive oxygen species (ROS) is well established. The underlying
mechanism involves oxidation of DNA by ROS. However, we have recently shown that hydrogen …
