“…Akitane and Jiankang Liu hypothesized that one possible mechanism for accelerated aging may be an increase in oxidative stress in this animal model. They observed age-associated biochemical changes in the brain and liver, and suggested that the mechanism of senescence acceleration in SAM is related to ROS-induced damage [48,49]. Then, Akitane carried out an experiment to administer the spin-trapping agent N-tert-alpha-phenylbutylnitrone (PBN) to SAM, and found that PBN treated animals as compared with control sham injected animals revealed a remarkable extension of the mean life span in both male and female groups.…”
