Graduate Theses - Chemistry and Biochemistry
Oxidative damage of DNA strands has been strongly linked with the development of diseases such as certain cancers, cystic fibrosis and Parkinson’s, as well as aging. In intercellular reactions involving hydrogen peroxide endogenous metals have been shown to increase the generation of site-specific base modifications through their formation of reactive oxygen species (ROS). The damage markers measured via HPLC are the 8-hydroxy-2’-deoxyguanosine (8-OHdG) and the dA-N1 oxide markers. The current study deals with the reduced form of the sulfur antioxidant glutathione (GSH) and elucidating its ameliorating effects against ROS formation. Comparative studies with the known radical-scavenging sulfur antioxidant dimethyl sulfoxide …
