长期的结果与热量和生长因子限制加上最近的结果与第一个干预药物表明,延缓衰老的步伐,以提高老年人的生活质量是在手边。这些方法靶向的生物系统是雷帕霉素(TOR)的靶标,其是细胞对各种刺激(包括应激物、生长因子以及营养物和能量状态)的反应的中心。从酵母到哺乳动物,降低其活性的延长寿命反应是高度保守的,这与衰老作为保护年轻细胞和动物生殖潜力的策略的进化是一致的。
Longstanding results with calorie and growth factor restriction plus recent results with the first interventional drug suggest that retarding the pace of aging to improve the quality of life of older people is at hand. The biological system targeted by these approaches is the target of rapamycin (TOR), which is central for cellular responses to a variety of stimuli including stressors, growth factors, and nutrients and energy states. That the life-extending response to reducing its activity is highly conserved from yeast to mammals is consistent with the evolution of aging as a strategy to preserve reproductive potential of young cells and animals.
