    Chromosome mis-segregation and cytokinesis failure in trisomic human cells

    Joshua M Nicholson et al.
    Aneuploidy can cause chromosome mis-segregation and specific cellular phenotypes driven by expression of genes on the extra chromosome.

    Centrosome age regulates kinetochore–microtubule stability and biases chromosome mis-segregation

    Ivana Gasic et al.
    The presence of cenexin at the old centrosome imposes a functional asymmetry on the mitotic spindle that impacts chromosome alignment and segregation.

    Meiosis I chromosome segregation is established through regulation of microtubule–kinetochore interactions

    Matthew P Miller et al.
    Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.
    1. Cell Biology

    Kinetochores attached to microtubule-ends are stabilised by Astrin bound PP1 to ensure proper chromosome segregation

    Duccio Conti et al.
    Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.

    Condensin controls cellular RNA levels through the accurate segregation of chromosomes instead of directly regulating transcription

    Clémence Hocquet et al.
    Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.

    Probing the catalytic functions of Bub1 kinase using the small molecule inhibitors BAY-320 and BAY-524

    Anna P Baron et al.
    Chemical inhibition of Bub1 shows that the catalytic activity is not required for normal mitotic progression, but it makes chromosome segregation and cell proliferation more sensitive to the effects of the anti-cancer drug Paclitaxel.

    The copy-number and varied strengths of MELT motifs in Spc105 balance the strength and responsiveness of the spindle assembly checkpoint

    Babhrubahan Roy et al.
    Cell biological and genetic analyses reveal how budding yeast cells optimize Spindle Assembly checkpoint signaling to maximize chromosome segregation accuracy and minimize unnecessary delays in anaphase onset.

    The evolutionary plasticity of chromosome metabolism allows adaptation to constitutive DNA replication stress

    Marco Fumasoni, Andrew W Murray
    Evolutionary adaptation to a constitutive perturbation of DNA replication reveals that adaptive mutations in three conserved pathways interact to restore faithful chromosome replication and segregation.

    The structural basis for dynamic DNA binding and bridging interactions which condense the bacterial centromere

    Gemma LM Fisher et al.
    A combination of structural, biochemical, single-molecule and in vivo methods are used to show how ParB locally condenses the bacterial chromosome near the origin and earmarks this region for segregation.

    BUB-1 promotes amphitelic chromosome biorientation via multiple activities at the kinetochore

    Frances Edwards et al.
    During chromosome segregation, BUB-1 performs multiple roles.
