中文摘要
我们拥有人类着丝粒成分的内在属性,发现它们具有惊人的弹性。这些弹性成分在结合到主动着丝点时会变得僵化,并抑制着丝粒的可及性,从而抑制转录。这些数据对癌细胞的易位产生了巨大的影响,我们已经在常染色质中绘制了着丝粒样域,这是脆弱的部位。目前的焦点是确定脆弱部位的着丝粒样结构域是否会改变这些部位的结构稳定性。
英文摘要
We have intrinsic properties of components of human centromeres, finding them to be surprisingly elastic. These elastic components become rigidified when incorporated into active kinetochores, and suppress centromeric accessibility, thereby suppressing transcription. These data have massive consequences for translocations in cancer cells where we have mapped centromere-like domains in euchromatin, which are sites of fragility. The current focus is to establish whether centromere-like domains in fragile sites can alter the structural stability of those sites.
