| Outline of Final Research Achievements |
We have been constructed a albumin fusion technology that is albe to create albumin dervaties with multiple functions. In the present study, we attmpted to develop a novel anti-oxidant that combined both blood retention property and cell penetrating activity based on albumin fusion technology. This hybrid type of aniti-oxidant exhibited superior radical scavenging activity both in vitro and in vivo. In addition, this anti-oxidant showed similar blood retention property comparable to wild type albumin. Poly-sulfared glutathiones that released from hybrid albumin efficiently transfered into the cells. Moreover, hybrid albumin inhibited radiation injury effectively and hence, significantly recovered the survibal rate against model mice of acute radiation syndrome via anti-oxidative and anti-inflammatory action. Thus, a hybrid type of anti-oxidant albumin that developed in this study has a potential as a novel therapeutics aganst acute radiation syndrome.
