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.
长期以来热量和生长因子限制的研究成果,加上首款干预性药物的最新研究成果表明,延缓衰老速度以改善老年人生活质量已近在咫尺。这些方法所针对的生物系统是雷帕霉素靶蛋白(TOR),它对于细胞对包括应激源、生长因子、营养物质和能量状态在内的多种刺激的反应至关重要。从酵母到哺乳动物,降低其活性所产生的延长寿命反应高度保守,这与衰老作为一种保护年轻细胞和动物生殖潜力的策略的进化是一致的。
