Abstract

We argue that the human evolutionary heritage with frequent adaptations through geological time to environmental change has affected a trade-off between offspring variability and cancer resistance, and thus favored cancer-prone individuals. We turn the attention to a factor setting the highly cancer-resistant naked mole rat apart from most other mammals: it has remained phenotypically largely unchanged since 30-50 million years ago. Research focusing on DNA stability mechanisms in 'living fossil' animals may help us find tools for cancer prevention and treatment.

摘要

我们认为,人类进化过程中经常适应地质时期的环境变化,这影响了后代变异性和癌症抵抗力之间的权衡,从而有利于易患癌症的个体。我们将注意力转向一个因素,这个因素使高度抗癌的裸鼹鼠与大多数其他哺乳动物区别开来:自 3000 万到 5000 万年前以来,它的表型基本没有变化。专注于“活化石”动物的 DNA 稳定性机制的研究可能有助于我们找到预防和治疗癌症的工具。
