非整倍体对细胞增殖具有矛盾的影响。在迄今为止分析的所有正常细胞中,已发现非整倍体降低细胞增殖速率。然而,非整倍体也是癌症的标志,癌症是一种增殖能力增强的疾病,并且在微生物的实验进化之后,非整倍体细胞经常被回收。因此,在某些情况下,非整倍性也可能具有生长有利的特性。非整倍体和染色体不稳定性的新模型揭示了核型不平衡对细胞表型的不同影响,并提出了理解非整倍体在发育和疾病中的作用的新方法。
Aneuploidy has a paradoxical effect on cell proliferation. In all normal cells analyzed to date, aneuploidy has been found to decrease the rate of cell proliferation. Yet, aneuploidy is also a hallmark of cancer, a disease of enhanced proliferative capacity, and aneuploid cells are frequently recovered following the experimental evolution of microorganisms. Thus, in certain contexts, aneuploidy may also have growth-advantageous properties. New models of aneuploidy and chromosomal instability have shed light on the diverse effects that karyotypic imbalances have on cellular phenotypes, and suggest novel ways of understanding aneuploidy’s role in development and disease.
