Given that RNA is involved in virtually all biological processes, it is perhaps not surprising that several RNA-binding proteins are associated with aging and with different age-related disorders. Other articles in this volume will discuss some specific examples of diseases where RNA plays a role that are also associated with aging, such as cancer and inflammation, so here I will discuss some general aspects of how RNA changes with the aging process. I will also discuss some specific examples of RNA-binding proteins that are associated with age-dependent neurological diseases as these provide an interesting framework to examine how lifetime mutations might lead to a late onset disease, although the answers to these questions are still not well understood.
鉴于 RNA 几乎参与所有的生物过程,几种 RNA 结合蛋白与衰老和不同的与年龄相关的疾病有关,这也许并不奇怪。本卷中的其他文章将讨论 RNA 在某些与衰老相关的疾病中发挥作用的具体例子,如癌症和炎症,因此,我将在这里讨论 RNA 随衰老过程变化的一些一般方面。我还将讨论一些与年龄相关的神经退行性疾病相关的 RNA 结合蛋白的具体例子,因为这些例子为研究终生突变如何导致迟发性疾病提供了一个有趣的框架,尽管这些问题的答案仍未得到很好的理解。
