Oxygen free radicals generated during radiation injury damage human erythrocyte membrane proteins including spectrin and band 3 protein. Results show an appreciable degree of spectrin and band 3 protein loss of about 55-65% due to crosslinking, and proteolysis when sodium dodecyl sulphate polyacrylamide gel electrophoresis carried out on erythrocyte ghosts. Oxidative damage to membrane proteins lead to degradation of its cytoskeletal components.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
