Abstract

Two paradigms central to geroscience research are that aging is associated with increased oxidative stress and increased cancer risk. Therefore, it could be deduced that cancers arising with ageing will show evidence of increased oxidative stress. Recent studies of gene expression in age-controlled breast cancer cases indicate that this deduction is false, posing parallax views of these two paradigms, and highlighting the unanswered question: does ageing cause or simply permit cancer development?

摘要

老年科学研究的两个核心范式是,衰老与氧化应激增加以及癌症风险增加相关。因此,可以推断,随着年龄增长而出现的癌症将显示出氧化应激增加的证据。最近对年龄匹配的乳腺癌病例进行的基因表达研究表明,这一推断是错误的,这对这两个范式提出了不同的观点,并突出了一个尚未解决的问题:衰老是导致癌症发生还是仅仅允许癌症发展?
