Chromothripsis is a one-step catastrophic event which plays an important role during cancer development. During chromothripsis, tens to hundreds of genomic rearrangements can occur within localized regions of the genome, and lead to the simultaneous creation of multiple cancer-driving aberrations. Given that chromothripsis has a cancer-wide incidence of 2-3%, its recent discovery has significant implications for our understanding of tumour biology and evolution.
染色体重排是一种单步灾难性事件,在癌症发展过程中起着重要作用。在染色体重排过程中,基因组的局部区域可能会发生数十到数百次的基因组重排,从而导致多个致癌异常的同时产生。鉴于染色体重排在癌症中的发生率为 2-3%,它的最近发现对我们理解肿瘤生物学和进化具有重要意义。
