Abstract
Oxygen metabolism is thought to impact on aging through the formation of reactive oxygen species (ROS) that are supposed to damage biological molecules. The study of p66(Shc), a crucial regulator of ROS level involved in aging dysfunction, suggests that the incidence of degenerative disease and longevity are determined by a specific signaling function of ROS other than their unspecific damaging property.
摘要
氧代谢被认为通过活性氧（ROS）的形成影响衰老，活性氧被认为会损害生物分子。对p66（Shc）的研究表明，退行性疾病的发生率和寿命是由活性氧的特定信号功能决定的，而不是由其非特异性损伤特性决定的。p66（Shc）是参与衰老功能障碍的活性氧水平的关键调节因子。
