Centromeres are the chromosomal domains required to ensure faithful transmission of the genome during cell division. They have a central role in preventing aneuploidy, by orchestrating the assembly of several components required for chromosome separation. However, centromeres also adopt a complex structure that makes them susceptible to being sites of chromosome rearrangements. Therefore, preservation of centromere integrity is a difficult, but important task for the cell. In this review, we discuss how centromeres could potentially be a source of genome instability and how centromere aberrations and rearrangements are linked with human diseases such as cancer.

着丝粒的黑暗面:涉及着丝粒 DNA 的结构异常的类型、原因和后果。
着丝粒是确保细胞分裂过程中基因组忠实传递所需的染色体结构域。它们通过协调染色体分离所需的几个组件的组装,在预防非整倍性方面发挥着核心作用。然而,着丝粒也采用复杂的结构,这使得它们容易成为染色体重排的位点。因此,保持着丝粒完整性对于细胞来说是一项困难但重要的任务。在这篇综述中,我们讨论了着丝粒如何可能成为基因组不稳定的根源,以及着丝粒畸变和重排如何与癌症等人类疾病相关。
