Cancer Evolution: No Room for Negative Selection.
Cell ( IF 64.5 ) Pub Date : 2017-Nov-16 , DOI: 10.1016/j.cell.2017.10.039

In this issue of Cell, Martincorena et al. and Campbell et al. interrogated the selection dynamics during tumor evolution using large-scale genomics datasets. They found that somatic mutations in cancer are largely neutral, highlighting a near-complete absence of negative selection. Neutral evolution enables tolerance of hypermutation, which defines a surprisingly large fraction of adult cancer.

癌症演变:没有负面选择的余地。

在《细胞》杂志上,Martincorena等人。和坎贝尔等。使用大规模基因组数据集询问了肿瘤演化过程中的选择动力学。他们发现癌症中的体细胞突变基本上是中性的,这表明几乎完全没有阴性选择。中性进化使人对超突变具有耐受性,超突变定义了成年癌症的很大一部分。
