衰老包括细胞功能的退化和变化,这些变化可能使细胞易发生致癌转化。在成年人中,辐射暴露后的致癌风险随着年龄的增长而增加。炎症反应的增加、氧化/抗氧化平衡的丧失、端粒的持续磨损、DNA损伤反应效率的下降以及有害的核组织都是与年龄相关的细胞变化,这些变化会引发对基因组完整性的严重威胁。在这篇综述中,我们讨论了所有这些因素之间的相互作用机制,提供了它们如何促进观察到的与年龄相关的辐射敏感性增加的综合观点。随着预期寿命的增加和医疗干预的增加,强调老年人辐射防护的好处是很重要的。因此,深入了解限制与衰老有关的辐射敏感性威胁的机制过程是目前最重要的。
Aging involves a deterioration of cell functions and changes that may predispose the cell to undergo an oncogenic transformation. The carcinogenic risks following radiation exposure rise with age among adults. Increasing inflammatory response, loss of oxidant/antioxidant equilibrium, ongoing telomere attrition, decline in the DNA damage response efficiency, and deleterious nuclear organization are age-related cellular changes that trigger a serious threat to genomic integrity. In this review, we discuss the mechanistic interplay between all these factors, providing an integrated view of how they contribute to the observed age-related increase in radiation sensitivity. As life expectancy increases and so it does the medical intervention, it is important to highlight the benefits of radiation protection in the elderly. Thus, a deep understanding of the mechanistic processes confining the threat of aging-related radiosensitivity is currently of foremost relevance.
