Research Abstract

The sulfhydryl-reactive oxidative stress agents 15d-PGJ_2, ONE and 8-nitro-cGMP induce phosphorylation and accumulation of p53 and apoptosis but DNA damage response. The ATM activation by 15d-PGJ_2 does not require a disulfide-cross-linked dimer formation of ATM, unlike the case by hydrogen peroxide. 15d-PGJ_2 affects the ATM-dependent metabolic regulation. These results obtained in this study characterize the mechanism of the ATM-dependent oxidative stress response that is different from DNA damage response and indicate involvement of the oxidative stress response in regulation of the metabolic system.
