Aging is debatably one of the biggest mysteries for humanity, a process consisting of myriads of genetic, molecular, environmental, and stochastic deleterious events, leading to a progressive loss of organism functionality. Aging research currently lacks a common conceptual framework, and one challenge in establishing it is the fact that aging is a highly complex process. To help develop a framework of standard aging rules, we suggest the use of deductive reasoning based on particle physics' principles. Specifically, the principles that we suggest applying to study aging are discreteness of processes, transformation as a result of interaction, and understanding of threshold. Using this framework, biological aging may be described as a sequence of highly discrete molecular transformations caused by a combination of various specific internal and external factors. Internal organismal function and interaction of an organism with the environment result in chronic accumulation of molecular damage and other deleterious consequences of metabolism and the consequent loss of system's functionality. The loss of functionality occurs as a series of thresholds the organism reaches before it turns into an utterly non-functional state. We discuss how having a common ground may benefit aging research, introduce the logic of new principles and analyze specific examples of how this framework could be used to study aging and design longevity interventions.
衰老是人类最大的谜团之一,可以被看作是一个由无数的遗传、分子、环境和随机有害事件组成的过程,导致生物体功能的逐渐丧失。衰老研究目前缺乏一个通用的概念框架,其中一个挑战是衰老过程非常复杂。为了帮助建立一个标准衰老规则的框架,我们建议使用基于粒子物理学原理的演绎推理。具体来说,我们建议应用于研究衰老的原则是过程的离散性、相互作用导致的转化以及对阈值的理解。使用这个框架,生物衰老可以被描述为一系列高度离散的分子转化,这些转化是由各种特定的内部和外部因素共同作用引起的。内部生物体功能和生物体与环境的相互作用导致分子损伤的慢性积累和代谢的其他有害后果,从而导致系统功能的丧失。功能丧失是生物体在变成完全无功能状态之前达到的一系列阈值。我们讨论了拥有共同基础如何使衰老研究受益,介绍了新原则的逻辑,并分析了如何使用这个框架来研究衰老和设计长寿干预措施的具体例子。
