Mechanisms by which whole chromosome instability lead to tumorigenesis have eluded the cancer research field. In this issue of Cancer Cell, Baker et al. show that CIN induced by a defective mitotic checkpoint, under certain genetic and tissue contexts, leads to accelerated loss of heterozygosity of a tumor suppressor gene.
全染色体不稳定导致肿瘤发生的机制一直困扰着癌症研究领域。在本期《癌细胞》杂志中,贝克等人表明,在特定的遗传和组织背景下,有缺陷的有丝分裂检查点诱导的染色体不稳定性(CIN)会导致肿瘤抑制基因杂合性加速丧失。
