S-glutathionylation of buccal cell proteins as biomarkers of exposure to hydrogen peroxide

Conclusions Buccal cells can predict exposure to ROS through increased levels of S-glutathionylation of proteins. These post-translationally modified proteins serve as biomarkers for the effects of H2O2 in the oral cavity and in the future, may be adaptable as extrapolated pharmacodynamic biomarkers for assessing the impact of other systemic drugs that cause ROS and/or impact redox homeostasis. General significance S-glutathionylation of buccal cell proteins can be used as a quantitative measure of exposure to ROS.
