Science：组织易患癌症是因为运气不好之故吗？

http://www.bio360.net/news/show/12738.html

Cristian Tomasetti 和 Bert Vogelstein分析了在31种不同人类组织中发表的有关干细胞分裂的数据，并将这些数据与这些组织在一生中发生癌症的比率进行了比较。

他们发现了在某个体一生中某组织内正常干细胞的分裂数与该特定组织中的癌症发生率之间有一个强的正相关。他们的发现提示，组织中的癌症发生率只有三分之一的差异可归因于遗传易感性和环境因素。

他们说，组织中的主要差异性只是因为“不佳的运气”，即其健康干细胞在分裂中复制其DNA时发生的随机突变。
