回答“为什么我们会衰老”的问题,就等于回答“生命本身是什么”的问题。关于我们衰老的原因和方式有无数的理论,但直到最近,衰老的定义——衰老——仍然不确定。在这里,我们总结了不同衰老模型的主要观点,特别强调伴随衰老的生化过程。尽管本质上很复杂,但衰老的特点是生物层次不同层次上发生的众多变化。因此,我们探讨了衰老过程中发生的一些最相关的变化,最后,我们概述了新兴衰老疗法的现状以及该研究领域的未来。从这种多维方法中可以清楚地看出,有必要采用一种将衰老研究与系统生物学结合起来的综合方法,这种方法能够为我们如何以及为何衰老提供新颖的见解。
Answering the question as to why we age is tantamount to answering the question of what is life itself. There are countless theories as to why and how we age, but, until recently, the very definition of aging – senescence – was still uncertain. Here, we summarize the main views of the different models of senescence, with a special emphasis on the biochemical processes that accompany aging. Though inherently complex, aging is characterized by numerous changes that take place at different levels of the biological hierarchy. We therefore explore some of the most relevant changes that take place during aging and, finally, we overview the current status of emergent aging therapies and what the future holds for this field of research. From this multi-dimensional approach, it becomes clear that an integrative approach that couples aging research with systems biology, capable of providing novel insights into how and why we age, is necessary.
