Research Abstract

We designed and constructed O2- hyperproduction XOR mutant knoched-in mouse which and dehydrogenase-type locked mutant knoched-in mouse. We propagated the starins. We purified mutant XOR from the knocked-in mutant mouse liver and confirmed the hyper production of superoxide anion. We are observing the phenotypes of the mutans and surveying pathological findings of organs.
